0001), while either incubation of isolated atria with licofelone (a dual COX/5-LOX inhibitor) or injection of licofelone to animals could reverse it, completely (P less then 0.01). Hydrocortisone (phospholipase A2 and COX-2 inhibitor) in vitro and in vivo (P less then 0.001, P less then 0.05, respectively) as well as indomethacin (COX inhibitor) in vitro and in vivo (P less then 0.05, P less then 0.01, respectively) exerted some lesser effects. Our data revealed that in endotoxemic rats, chronotropic hyporesponsiveness to cholinergic stimulation was modulated by the dual COX/5-LOX inhibitor licofelone, and this effect is comparable with hydrocortisone and indomethacin.Mucopolysaccharidosis III (Sanfilippo syndrome, MPS III) is caused by lysosomal enzyme deficiency, which is a rare autosomal recessive hereditary disease. For now, there is no approved treatment for MPS III despite lots of efforts providing new vision of its molecular basis, as well as governments providing regulatory and economic incentives to stimulate the development of specific therapies. Those efforts and incentives attract academic institutions and industry to provide potential therapies for MPS III, including enzyme replacement therapies, substrate reduction therapies, gene and cell therapies, and so on, which were discussed in this paper.Given the role of Cav3.2 isoform among T-type Ca2+ channels (T-channels) in somatic and visceral nociceptive processing, we analyzed the contribution of Cav3.2 to butyrate-induced colonic pain and nociceptor hypersensitivity in mice, to evaluate whether Cav3.2 could serve as a target for treatment of visceral pain in irritable bowel syndrome (IBS) patients. Mice of ddY strain, and wild-type and Cav3.2-knockout mice of a C57BL/6J background received intracolonic administration of butyrate twice a day for 3 days. Referred hyperalgesia in the lower abdomen was assessed by von Frey test, and colonic hypersensitivity to distension by a volume load or chemicals was evaluated by counting nociceptive behaviors. Spinal phosphorylated ERK was detected by immunohistochemistry. Cav3.2 knockdown was accomplished by intrathecal injection of antisense oligodeoxynucleotides. Butyrate treatment caused referred hyperalgesia and colonic hypersensitivity to distension in ddY mice, which was abolished by T-channel blockers and/or Cav3.2 knockdown. Butyrate also increased the number of spinal phosphorylated ERK-positive neurons following colonic distension in the anesthetized ddY mice. The butyrate-treated ddY mice also exhibited T-channel-dependent colonic hypersensitivity to intracolonic Na2S, known to enhance Cav3.2 activity, and TRPV1, TRPA1 or proteinase-activated receptor 2 (PAR2) agonists. Wild-type, but not Cav3.2-knockout, mice of a C57BL/6J background, after treated with butyrate, mimicked the T-channel-dependent referred hyperalgesia and colonic hypersensitivity in butyrate-treated ddY mice. Our study provides definitive evidence for an essential role of Cav3.2 in the butyrate-induced colonic pain and nociceptor hypersensitivity, which might serve as a target for treatment of visceral pain in IBS patients.Glucagon-like peptide-1 (GLP-1) is an endogenous gut hormone and a key regulator in maintaining glucose homeostasis by stimulating insulin secretion. Its natural cleavage product GLP-1 (9-36), which was formerly considered a "bio-inactive" metabolite mainly due to its low affinity for GLP-1 receptor, possesses unique properties such as cardiovascular protection. Little is known about the effects and mechanisms of GLP-1 (9-36) in cerebral ischemia and reperfusion injury. Here, we report that systemic application of GLP-1 (9-36) in adult mice facilitated functional recovery and reduced infarct volume, astrogliosis, and neuronal apoptosis following middle cerebral artery occlusion and reperfusion. Interestingly, these effects were still observed in GLP-1 receptor knockout (Glp-1rKO) mice but were partially reversed in insulin-like growth factor 1 (IGF-1) receptor knockdown (Igf-1rKD) mice. Primary astrocytes were cultured and subjected to oxygen-glucose deprivation/reoxygenation (OGD/R), and enzyme-linked immunosorbent assay indicated that GLP-1 (9-36) pretreatment reduces tumor necrosis factor-α, interleukin (IL)-1β, and IL-6 levels. This effect was not diminished in Glp-1rKO astrocytes but was reversed in Igf-1rKO astrocytes, emphasizing that the anti-inflammatory effect of GLP-1 (9-36) in astrocytes is independent of GLP-1 receptor signaling and is instead mediated by IGF-1 receptor. Immunoprecipitation experiments showed that GLP-1 (9-36) directly interacts with IGF-1 receptor in astrocytes. Western blot data indicated that GLP-1 (9-36) activates IGF-1 receptor and downstream PI3K-AKT pathway in astrocytes upon OGD/R injury, which was abrogated by preincubation with IGF-1 receptor autophosphorylation inhibitor picropodophyllin. Thus, our findings suggest that GLP-1 (9-36) improved stroke outcome by reducing inflammation in astrocytes via interaction with IGF-1 receptor.Are diseases caused by aging? What are the mechanisms of aging? Do all species age? These hotly debated questions revolve around a unitary definition of aging. https://www.selleckchem.com/products/bmn-673.html Because we use the word "aging" so frequently, both colloquially and scientifically, we rarely pause to consider whether this word maps to an underlying biological phenomenon, or whether it is simply a grab-bag of diverse phenomena linked more by our mental associations than by any underlying biology. Here, we consider how the presence of the colloquial word "aging" generates a cognitive bias towards supposing there is a unitary biological phenomenon. We ask what kind of evidence would support or refute that idea, and subsequently show clear evidence at multiple levels that aging is not a unitary phenomenon. In particular, the known aging pathways lead to heterogeneous outputs, not a single coordinated phenomenon. From levels ranging from cellular/molecular to clinical to demographic to evolutionary, we show how the supposition that aging is a unitary phenomenon can mislead and distract us from asking the best questions. For major sub-disciplines of aging biology, we show how going beyond the notion of unitary aging can hone the paradigm and help advance the pace of discovery.

a) the stimulatory effects of GIP and GLP-1 differ markedly ISR potentiation increases linearly with GLP-1 over the whole dose range, while with GIP infusion it reaches a plateau at ~100 pmol/L GIP, with ISR potentiation of ~2 fold; b) ISR potentiation in T2D is reduced by ~50% for GIP and by ~40% for GLP-1; c) the literature search of GIP in NGT subjects confirmed the saturative effect on insulin secretion. We show that incretin potentiation of ISR is reduced in T2D, but not abolished, and that the lack of effects of pharmacological GIP doses is due to saturation of the GIP effect more than insensitivity to GIP in T2D. We show that incretin potentiation of ISR is reduced in T2D, but not abolished, and that the lack of effects of pharmacological GIP doses is due to saturation of the GIP effect more than insensitivity to GIP in T2D. In this study, we aimed to identify the determinants of mitochondrial dysfunction in skeletal muscle (SKLM) of subjects with type 2 diabetes (T2DM), and to evaluate the effect of pioglitazone (PIO) on SKLM mitochondrial proteome. Two different groups of adults were studied. Group I consisted of 8 individuals with normal glucose tolerance (NGT) and 8 with T2DM, subjected to SKLM mitochondrial proteome analysis by 2D-gel electrophoresis followed by mass spectrometry-based protein identification. Group II included 24 individuals with NGT and 24 with T2DM, whose SKLM biopsies were subjected to immunoblot analysis. Of the 24 subjects with T2DM, 20 were randomized to receive placebo or PIO (15 mg daily) for 6 months. After 6 months of treatment, SKLM biopsy was repeated. Mitochondrial proteomic analysis on Group I revealed that several mitochondrial proteins involved in oxidative metabolism were differentially expressed between T2DM and NGT groups, with a downregulation of ATP synthase alpha chain (ATP5A), el treated with PIO for 6 months we found a restored SKLM protein abundance of ATP5A, ETFA, CX6B1, and mitofilin. Moreover, protein levels of HCDH and ECH1 were reduced by -10% and - 15% respectively (P ≤ 0.05 for both) after PIO treatment. Type 2 diabetes is associated with reduced levels of mitochondrial proteins involved in oxidative phosphorylation and an increased abundance of enzymes implicated in fatty acid catabolism in SKLM. PIO treatment is able to improve SKLM mitochondrial proteomic profile in subjects with T2DM. Type 2 diabetes is associated with reduced levels of mitochondrial proteins involved in oxidative phosphorylation and an increased abundance of enzymes implicated in fatty acid catabolism in SKLM. PIO treatment is able to improve SKLM mitochondrial proteomic profile in subjects with T2DM.Transcription factors (TFs) are major contributors to cancer risk and somatic development. In preclinical and clinical studies, direct or indirect inhibition of TF-mediated oncogenic gene expression profiles have proven to be effective in many tumor types, highlighting this group of proteins as valuable therapeutic targets. In spite of this, our understanding of TFs in epithelial ovarian cancer (EOC) is relatively limited. EOC is a heterogeneous disease composed of five major histologic subtypes; high-grade serous, low-grade serous, endometrioid, clear cell and mucinous. Each histology is associated with unique clinical etiologies, sensitivity to therapies, and molecular signatures - including diverse transcriptional regulatory programs. While some TFs are shared across EOC subtypes, a set of TFs are expressed in a histotype-specific manner and likely explain part of the histologic diversity of EOC subtypes. Targeting TFs present with unique opportunities for development of novel precision medicine strategies for ovarian cancer. This article reviews the critical TFs in EOC subtypes and highlights the potential of exploiting TFs as biomarkers and therapeutic targets.Myeloperoxidase (MPO) is a prominent mammalian heme peroxidase and a fundamental component of the innate immune response against microbial pathogens. In recent times, MPO has received considerable attention as a key oxidative enzyme capable of impairing the bioactivity of nitric oxide (NO) and promoting endothelial dysfunction; a clinically relevant event that manifests throughout the development of inflammatory cardiovascular disease. Increasing evidence indicates that during cardiovascular disease, MPO is released intravascularly by activated leukocytes resulting in its transport and sequestration within the vascular endothelium. At this site, MPO catalyzes various oxidative reactions that are capable of promoting vascular inflammation and impairing NO bioactivity and endothelial function. In particular, MPO catalyzes the production of the potent oxidant hypochlorous acid (HOCl) and the catalytic consumption of NO via the enzyme's NO oxidase activity. An emerging paradigm is the ability of MPO to also influunction. Finally, we deliver a detailed appraisal of the different pharmacological strategies available for targeting the catalytic and non-catalytic modes-of-action of MPO in order to protect against endothelial dysfunction in cardiovascular disease.A novel series of deoxyvasicinone-tetrahydro-beta-carboline hybrids were synthesized and evaluated as acetylcholinesterase (AChE) and β-amyloid peptide (Aβ) aggregation inhibitors for the treatment of Alzheimer's disease. The results revealed that the derivatives had multifunctional profiles, including AChE inhibition, Aβ1-42 aggregation inhibition, and neuroprotective properties. Inspiringly, hybrids 8b and 8d displayed excellent inhibitory activities against hAChE (IC50 = 0.93 and 1.08 nM, respectively) and Aβ1-42 self-aggregation (IC50 = 19.71 and 2.05 μM, respectively). In addition, 8b and 8d showed low cytotoxicity and good neuroprotective activity against Aβ1-42-induced damage in SH-SY5Y cells. To investigate the possible influence of polycyclic aromatic hydrocarbons (PAHs) exposure on neurodevelopment of toddlers at the age of 12 months. Totally 306 subjects were recruited from the Qingdao Birth Cohort established in 2014. https://www.selleckchem.com/products/d-lin-mc3-dma.html PAH-DNA adducts in toddlers' umbilical cord blood samples, hydroxyl-PAH metabolites in their urine samples and the developmental quotients (DQs) were measured. Sex, gestational age, birth weight, and maternal educational background were adjusted to analyze the influence of the PAH exposure on the neurodevelopment of the toddlers using multivariate linear regression model. Pearson correlation test showed that the logarithmic values of hydroxyl-PAH were negatively correlated with the DQs. Multivariate linear regression analysis indicated that logarithmic concentration of 1(9)- hydroxyphenanthrene was still associated with the DQs of the fine motor behaviors with β and 95% confidential interval (CI) of -1.137 (-2.053, -0.222), together with PAH-DNA adducts [β (95% CI) -0.577 (-0.

In the case of reduced cellular immunity the previously dormant varicella zoster virus (VZV) causes the characteristic belt-shaped vesicular exanthema of herpes zoster. The initial clinical symptoms of herpes zoster are often non-specific and may lead to initial misdiagnosis. A common complication of herpes zoster is postherpetic neuralgia (PHN) but secondary hematogenic dissemination is only rarely observed. In addition to general factors, such as advanced age and female gender, inflammatory rheumatic diseases and their immunosuppressive treatment are important risk factors for the occurrence of herpes zoster. Antiviral therapy initiated in the first 72 h after the onset of exanthema reduces acute symptoms and the risk of complications. The subunit inactivated vaccine, which has been available since 2018, is highly effective and relatively well-tolerated but randomized controlled trials in patients with drug-induced immunosuppression for inflammatory rheumatic diseases are still pending. This study aimed to compare the outcomes at the clinical and functional levels of suprapatellar (SP) and infrapatellar (IP) approaches for intramedullary nailing in treating tibial shaft fracture. Patients who underwent tibial shaft fracture intramedullary nailing by the SP approach or IP approach in a trauma center were retrospectively reviewed. The demographics, intraoperative fluoroscopy time, operation time, blood loss, irrigation volume, postoperative X-ray alignment, and complications of patients were compared between the two groups under different approaches. https://www.selleckchem.com/products/mrtx849.html Lysholm knee score, visual analog score (VAS), and incidence of anterior knee pain (AKP) were assessed 1year after surgery. The study finally included well-documented 81 patients (38 SP versus 43 IP). The SP group exhibited significantly shorter intraoperative fluoroscopy time than that of the IP group (81.7 ± 14.5s vs. 122.0 ± 24.3s, P < 0.001). Both aspects recorded a precise reduction of the fracture angulation (2.1 ± 1.2° vs 3.1 ± 1.5ullary nailing through the SP approach in treating tibial shaft fractures can effectively shorten the intraoperative fluoroscopy time, correct coronal plane angulation and translation deformity, reduce the incidence of AKP and improve postoperative function. Cytochrome P450s (CYPs) are a class of hemoproteins involved in drug metabolism. It has been reported that body composition, proportion of dietary macronutrients, fasting and nutritional status can interfere with the activity of drug-metabolizing CYPs. The present systematic review was conducted to summarize the effect of obesity, weight reduction, macronutrients, fasting and malnutrition on the CYP-mediated drug metabolism. PubMed (Medline), Scopus, Embase and Cochrane Library databases and Google Scholar were searched up to June 2020 to obtain relevant studies. The PRISMA guidelines were employed during all steps. Two reviewers independently extracted the information from the included studies. Studies investigating CYPs activity directly or indirectly through pharmacokinetics of probe drugs, were included. Increase in clearance (CL) or decrease in elimination half-life (t½) and area under the curve (AUC) of probe drugs were considered as increase in CYPs activity. A total of 6545 articles were obtaiss of medical care.Developing biocompatible, synthetic oxygen carriers is a consistently challenging task that researchers have been pursuing for decades. Perfluorocarbons (PFC) are fascinating compounds with a huge capacity to dissolve gases, where the respiratory gases are of special interest for current investigations. Although largely chemically and biologically inert, pure PFCs are not suitable for injection into the vascular system. Extensive research created stable PFC nano-emulsions that avoid (i) fast clearance from the blood and (ii) long organ retention time, which leads to undesired transient side effects. PFC-based oxygen carriers (PFOCs) show a variety of application fields, which are worthwhile to investigate. To understand the difficulties that challenge researchers in creating formulations for clinical applications, this review provides the physical background of PFCs' properties and then illuminates the reasons for instabilities of PFC emulsions. By linking the unique properties of PFCs and PFOCs to physiology, it elaborates on the response, processing and dysregulation, which the body experiences through intravascular PFOCs. Thereby the reader will receive a scientific and easily comprehensible overview why PFOCs are precious tools for so many diverse application areas from cancer therapeutics to blood substitutes up to organ preservation and diving disease.Patients with diabetes who undergo a surgical intervention have an increased risk of metabolic derailment, anesthesiological complications, postoperative infections and cardiovascular events. The treatment of diabetes mellitus is subject to a continuous further development due to pharmaceutical and technical innovations. This article presents the implications of the current concepts of diabetes treatment for perioperative medicine, particularly the changes due to new oral antidiabetic agents and insulin pump treatment. Some of the currently available guidelines are discussed with respect to the care of diabetes patients in childhood and adulthood in connection with an operation. Finally, possible perspectives in the field of monitoring and treatment of diabetes patients are discussed.The use of dynamic finite element analysis to investigate the biomechanical behavior of the knee joint is mainly based on movement of the joint. Challenges are associated with simulation of knee joint flexion-extension activity. This study investigated changes in the length and stress state of ligaments during lunge with a displacement controlled finite element analysis of the knee joint based on in vivo fluoroscopic kinematic data. The geometric center axis (GCA) was used to represent knee kinematics to quantify femoral motion relative to the tibia. Because the GCA was considered as a functional flexion axis, 2 degrees of freedom could be reduced. Published data on the in vivo fluoroscopic kinematic features of the GCA were used to establish the equations for degrees of freedom. Data for 4 degrees of freedom were obtained simultaneously at every 5° of knee flexion. Displacement and rotation were applied to the femur and tibia to produce relative displacement, and the elongation and stress state of the knee ligaments were computed.

reast cancer patients. The aim of the present research is to investigate the efficacy of L-carnitine (LC) as a complementary therapy to diclofenac sodium (Dic) treatment in a mono-iodoacetate (MIA) induced knee osteoarthritis (OA) rat model, with respect to pain relief and the underlying pathology. Fifty adult male albino rats were randomly divided into five groups (n=10) Control, OA, OA/Dic, OA/LC, and OA/Dic+LC. Knee diameter and pain assessment tests were done weekly. After four weeks, serum malondialdehyde, reduced glutathione, interleukin 1-β, tumor necrosis factor-alpha, prostaglandin E2, and bone-specific alkaline phosphatase were measured. The injected knees were removed and processed for the histological and immunohistological study of matrix metalloproteinase-13 (MMP-13) and cyclooxygenase 2 (COX-2). Also, histological examination of dorsal root ganglia and calcitonin gene-related peptide (CGRP) expression in the spinal cord were assessed. Treatment with Dic and/or LC significantly reduced knee swelling, improved pain-related behaviors, inflammatory and oxidative stress markers, attenuated the MIA-mediated histopathological alteration in the knee joint, and down-regulated expression of MMP-13 and COX-2 in the knee joint. It, also, significantly reduced CGRP expression, compared with the OA group. Dic+LC showed a better effect in improving some parameters than each treatment alone. LC plus Dic is a more effective therapy than Dic alone for OA treatment. LC plus Dic is a more effective therapy than Dic alone for OA treatment. Adipose tissue is one of the most important endocrine organs that liberates many metabolic mediators such as hormones, cytokines, and chemokines. Different types of fatty acids have key roles in adipogenesis. The aim of this study was to evaluate the effects of two essential fatty acids, including Arachidonic acid (AA) and Eicosapentaenoic acid (EPA), on the process of adipogenicity in human Adipose-Derived Stem Cells (hADSCs). After immunophenotyping of hADSCs by flowcytometry, they were differentiated into adipocytes and simultaneously exposed to 30 μM and 60 μM of AA and 25 μM and 50 μM of EPA. Further, along with the MTS assay, the activity of glycalaldehyde-3-phosphate dehydrogenase (GAPDH) was also measured. In addition, expression of lipid markers including peroxisome proliferator-activated receptor γ2 (PPARγ2) and glucose transporter 4 (GLUT4) was evaluated, and the neutral lipid contents were determined using Oil red O staining. MTS evaluation showed a significant decrease in proliferation in all treatment groups compared to the control group. Based on oil red O staining, fat droplets in the AA treatment groups were higher than in controls. The expression of PPARγ2 and GLUT4 genes and proteins increased in almost all AA and EPA groups compared to control. In addition, GAPDH activity was higher in AA groups than in the control group. In general, while different concentrations of EPA did not increase the adipogenic process compared to the control group, stimulation of differentiation to adipocytes was largely determined by the AA. The result indicates a positive effect of omega-6 versus omega-3 in stimulating the pathways of adipogenesis. The result indicates a positive effect of omega-6 versus omega-3 in stimulating the pathways of adipogenesis. Granular and lattice corneal dystrophies (GCDs & LCDs) are autosomal dominant inherited disorders of the cornea. Due to genetic heterogeneity and large genes, unraveling the mutation is challenging. Patients underwent comprehensive clinical examination, and targeted next-generation sequencing (NGS) was used for mutation detection. Co-segregation and analysis was accomplished. Patients suffered from GCD. NGS disclosed a known pathogenic variant, c.371G>A (p.R124H), in exon 4 of . The variant co-segregated with the phenotype in the family. Homozygous patients manifested with more severe phenotypes. Variable expressivity was observed among heterozygous patients. The results, in accordance with previous studies, indicate that the c.371G>A in TGFBI is associated with GCD. Some phenotypic variations are related to factors such as modifier genes, reduced penetrance and environmental effects. A in TGFBI is associated with GCD. Some phenotypic variations are related to factors such as modifier genes, reduced penetrance and environmental effects. To investigate and test the hypotheses that TGF-β1 enhanced myocardial differentiation through Wnt/β-catenin pathway with rat bone marrow mesenchymal stem cells (BMSCs). Lentiviral vectors carrying the TGF-β1 gene were transduced into rat BMSCs firstly. Then several kinds of experimental methods were used to elucidate the related mechanisms by which TGF-β1 adjusts myocardial differentiation in rat BMSCs. Immunocytochemistry revealed that cTnI and Cx43 expressed positively in the cells that were transduced with TGF-β1. The results of Western blot (WB) test showed that the levels of intranuclear β-catenin and total β-catenin were all significantly decreased. However, the cytoplasmic β-catenin level was largely unchanged. Moreover, the levels of GSK-3β were largely unchanged in BMSCs, whereas phosphorylated GSK-3β was significantly decreased in BMSCs. When given the activator of Wnt/β-catenin pathway (lithium chloride, LiCl) to BMSCs transducted with TGF-β1, β-catenin was increased, while phosphorylated β-catenin was decreased. In addition, cyclinD1, MMP-7, and c-Myc protein in BMSCs transducted with Lenti-TGF-β1-GFP were significantly lower. These results indicate that TGF-β1 promotes BMSCs cardiomyogenic differentiation by promoting the phosphorylation of β-catenin and inhibiting cyclinD1, MMP-7, and c-Myc expression in Wnt/β-catenin signaling pathway. These results indicate that TGF-β1 promotes BMSCs cardiomyogenic differentiation by promoting the phosphorylation of β-catenin and inhibiting cyclinD1, MMP-7, and c-Myc expression in Wnt/β-catenin signaling pathway. Human T cell leukaemia virus type 1 (HTLV-1) is associated with adult T cell leukaemia (ATL), a malignant lymphoproliferative disease that infects CD4 T cells. It is not clear why the majority of HTLV-1-infected individuals remain asymptomatic carries (ACs) and a minority develop ATL. Cellular immune response has a critical role in ATL and destroys malignant and HTLV-1-infected cells. Perforin and granzyme have important functional roles in apoptosis and destruction of infected cells. In the present study we examined the role of perforin and granzyme in ATL patients and ACs. Peripheral blood mononuclear cells (PBMCs) were isolated from ATL patients and ACs by using Ficoll-hypaque density centrifugation. RNA was extracted and cDNA was synthesized. A real-time PCR TaqMan method was designed and optimized for evaluation of perforin, granzyme, tax, and HBZ gene expression. https://www.selleckchem.com/products/endoxifen-hcl.html HTLV-1 proviral load (PVL) was quantified in patients with ATL and ACs. The mRNA expression of tax and HBZ was significantly higher in ATL patients than ACs ( =0.

About 12% (~21 million US adults) had poor CVH. Compared with individuals with optimal CVH, those with poor CVH had higher odds of reporting poor patient-provider communication (odds ratio, 1.14; 95% CI, 1.05-1.24), poor healthcare satisfaction (odds ratio, 1.15; 95% CI, 1.08-1.22), poor perception of health (odds ratio, 5.89; 95% CI, 5.35-6.49), at least 2 disability days off work (odds ratio, 1.39; 95% CI, 1.30-1.48), and lower health-related quality of life scores. Conclusions Among US adults without cardiovascular disease, meeting a lower number of ideal CVH metrics is associated with poor patient-reported healthcare experience, poor perception of health, and lower health-related quality of life. Preventive measures aimed at optimizing ideal CVH metrics may improve patient-reported outcomes among this population.Background It has been widely recognized that obstructive sleep apnea (OSA) is linked to cardiovascular disease. Yet, randomized controlled studies failed to demonstrate a clear cardiovascular benefit from OSA treatment, mainly because of poor adherence to continuous positive airway pressure (CPAP). To date, no prior study has assessed the effect of CPAP treatment on daytime resting heart rate, a strong predictor of adverse cardiovascular outcomes and mortality. Methods and Results We conducted a randomized controlled study in 39 participants with OSA and prediabetes, who received either in-laboratory all-night (ie, optimal) CPAP or an oral placebo for 2 weeks. During daytime, participants continued daily activities outside the laboratory. Resting heart rate was continuously assessed over 19 consecutive days and nights using an ambulatory device consisting of a single-lead ECG and triaxis accelerometer. Compared with placebo, CPAP reduced daytime resting heart rate (treatment difference, -4.1 beats/min; 95% CI, -6.5 to -1.7 beats/min; P=0.002). The magnitude of reduction in daytime resting heart rate after treatment significantly correlated with the magnitude of decrease in plasma norepinephrine, a marker of sympathetic activity (r=0.44; P=0.02), and the magnitude of decrease in OSA severity (ie, apnea-hypopnea index [r=0.48; P=0.005], oxygen desaturation index [r=0.50; P=0.003], and microarousal index [r=0.57; P less then 0.001]). Conclusions This proof-of-concept randomized controlled study demonstrates, for the first time, that CPAP treatment, when optimally used at night, reduces resting heart rate during the day, and therefore has positive cardiovascular carry over effects. These findings suggest that better identification and treatment of OSA may have important clinical implications for cardiovascular disease prevention. Registration URL https/// www.clinicaltrials.gov; Unique identifier NCT01156116.MiR-145-5p is high-expressed in human vascular endothelial cells (HUVECs) and alternatively activated macrophages (M2). However, whether miR-145-5p can reduce HUVEC damage by regulating macrophage immunophenotype is less reported. THP-1 was stimulated by Phorbolate-12-myristate-13-acetate, LPS and IFN-γ, and IL-4 to differentiate into macrophages (M0, M1 and M2). The expressions of macrophage markers were detected by Western blotting, and the expressions of miR-145-5p and kruppel-like factor-14 (KLF14) were detected by qRT-PCR. Dual-luciferase reporter assay was used to analyze the targeted relationship of miR-145-5p and KLF14. HUVEC injury was induced by LPS and then co-cultured with M1 transfected by miR-145-5p mimic. The effect of miR-145-3p on proliferation and metastasis of LPS-induced HUVECs was detected by MTT, clone formation, scratch assay and Transwell. We found that the expression of miR-145-5p was higher in M2 than that in M1. MiR-145-5p expression was down-regulated during M2-to-M1, but up-regulated during M1-to-M2. The expressions of IL-1β and iNOS were down-regulated, while the protein expressions of CCL17 and Arg-1 were up-regulated by miR-145-5p mimic in M0. The viability, proliferation, migration and invasion of HUVECs were promoted, however, LDH activity of the HUVECs was inhibited by mimics. In addition, KLF14 was predicted as the target gene for miR-145-5p in HUVECs. Collectively, our results demonstrate that miR-145-5p inhibited cell proliferation of LPS-treated HUVECs possibly through regulating macrophage polarization to M2.The American Venous Forum (AVF) and the Society for Vascular Surgery set forth these guidelines for the management of endothermal heat-induced thrombosis (EHIT). The guidelines serve to compile the body of literature on EHIT and to put forth evidence-based recommendations. The guidelines are divided into the following categories classification of EHIT, risk factors and prevention, and treatment of EHIT.One major feature is to standardize the reporting under one classification system. The Kabnick and Lawrence classification systems are now combined into the AVF EHIT classification system. The novel classification system affords standardization in reporting but also allows continued combined evaluation with the current body of literature. Recommendations codify the use of duplex ultrasound for the diagnosis of EHIT. Risk factor assessments and methods of prevention including mechanical prophylaxis, chemical prophylaxis, and ablation distance are discussed.Treatment guidelines are tailored to the AVF EHIT class (ie, I, II, III, IV). Reference is made to the use of surveillance, antiplatelet therapy, and anticoagulants as deemed indicated, and the recommendations incorporate the use of the novel direct oral anticoagulants. Last, EHIT management as it relates to the great and small saphenous veins is discussed. Mortality in SLE has a bimodal peak with early deaths mainly related to disease activity and infection. https://www.selleckchem.com/products/Decitabine.html Although mortality has reduced over years, it is still two to three folds compared to the general population. In India due to increased burden of infection and limited access to health care, the causes may be different. Retrospective, review of records of all adult SLE patients fulfilling ACR 1997 criteria, who died in hospital between 2000-2019 at a teaching hospital in India was done. In addition, baseline clinical features were extracted for all adult SLE patients seen during this period.Infections were either bacteriologically proven or based on clinicradiological or serologic evidence. Active disease was defined as SLEDAI 2k ≥ 5. Logistic regression was performed to ascertain risk factors for mortality. A total of 1337 (92% females) patient records were reviewed .The mean age at presentation was 29.9 ± 9 years.60-75% of patients had fever, mucocutaneous disease and arthritis, while nephritis, hematologic, serositis and neurologic involvement was seen in 48.

Our approach provides an efficient way to enrich OGSCs without using OGSC-specific surface markers or transgenic strains expressing OGSC-specific reporter proteins.Eriocaulaceae (Poales) differ from potentially related Xyridaceae in pattern of floral organ arrangement relative to subtending bract (with median sepal adaxial). Some Eriocaulaceae possess reduced and non-trimerous perianth, but developmental data are insufficient. We conducted a SEM investigation of flower development in three species of Eriocaulon to understand whether organ number and arrangement are stable in E. redactum, a species with a highly reduced calyx and reportedly missing corolla. Early flower development is similar in all three species. Male and female flowers are indistinguishable at early stages. Despite earlier reports, both floral types uniformly possess three congenitally united sepals and three petals in E. redactum. Petals and inner stamens develop from common primordia. We assume that scanning electron microscopy should be used in taxonomic accounts of Eriocaulon to assess organ number and arrangement. Two types of corolla reduction are found in Eriocaulaceae suppression and complete loss of petals. Common petal-stamen primordia in Eriocaulon do not co-occur with delayed receptacle expansion as in other monocots but are associated with retarded petal growth. The 'reverse' flower orientation of Eriocaulon is probably due to strictly transversal lateral sepals. Gynoecium development indicates similarities of Eriocaulaceae with restiids and graminids rather than with Xyridaceae.Drought induces several challenges for plant development, growth, and production. These challenges become more severe, in particular, in arid and semiarid countries like Egypt. In terms of production, barley ranks fourth after wheat, maize, and rice. Seed germination and seedling stages are critical stages for plant establishment and growth. In the current study, 60 diverse barley genotypes were tested for drought tolerance using two different treatments control (0-PEG) and drought (20%-PEG). https://www.selleckchem.com/products/kd025-(slx-2119).html Twenty-two traits were estimated for seed germination and seedling parameters. All traits were reduced under drought stress, and a significant variation was found among genotypes under control and stress conditions. The broad-sense heritability estimates were very high under both control and drought for all traits. It ranged from 0.63 to 0.97 under the control condition and from 0.89 to 0.97 under drought, respectively. These high heritabilities suggested that genetic improvement of drought tolerance in barley at both stages is feasible. The principal component analysis revealed that root-related parameters account for the largest portion of phenotypic variation in this collection. The single-marker analysis (SMA) resulted in 71 quantitative trait loci (QTLs) distributed across the seven chromosomes of barley. Thirty-three QTLs were detected for root-length-related traits. Many hotspots of QTLs were detected for various traits. Interestingly, some markers controlled many traits in a pleiotropic manner; thus, they can be used to control multiple traits at a time. Some QTLs were constitutive, i.e., they are mapped under control and drought, and targeting these QTLs makes the selection for drought tolerance a single-step process. The results of gene annotation analysis revealed very potential candidate genes that can be targeted to select for drought tolerance.In electronic nicotine delivery systems (ENDS), coil resistance is an important factor in the generation of heat energy used to change e-liquid into vapor. An accurate and unbiased method for testing coil resistance is vital for understanding its effect on emissions and reporting results that are comparable across different types and brands of ENDS and measured in different laboratories. This study proposes a robust, accurate and unbiased method for measuring coil resistance. An apparatus is used which mimics the geometric configuration and assembly of ENDS reservoirs, coils and power control units. The method is demonstrated on two commonly used ENDS devices-the ALTO by Vuse and JUUL. Analysis shows that the proposed method is stable and reliable. The two-wire configuration introduced a positive measurement bias of 0.086 (Ω), which is a significant error for sub-ohm coil designs. The four-wire configuration is far less prone to bias error and is recommended for universal adoption. We observed a significant difference in the coil resistance of 0.593 (Ω) (p less then 0.001) between the two products tested. The mean resistance and standard deviation of the reservoir/coil assemblies was shown to be 1.031 (0.067) (Ω) for ALTO and 1.624 (0.033) (Ω) for JUUL. The variation in coil resistance between products and within products can have significant impacts on aerosol emissions.Iron is an essential mineral participating in different functions of the organism under physiological conditions. Numerous biological processes, such as oxygen and lipid metabolism, protein production, cellular respiration, and DNA synthesis, require the presence of iron, and mitochondria play an important role in the processes of iron metabolism. In addition to its physiological role, iron may be also involved in the adaptive processes of myocardial "conditioning". On the other hand, disorders of iron metabolism are involved in the pathological mechanisms of the most common human diseases and include a wide range of them, such as type 2 diabetes, obesity, and non-alcoholic fatty liver disease, and accelerate the development of atherosclerosis. Furthermore, iron also exerts potentially deleterious effects that may be manifested under conditions of ischemia/reperfusion (I/R) injury, myocardial infarction, heart failure, coronary artery angioplasty, or heart transplantation, due to its involvement in reactive oxygen species (ROS) production. Moreover, iron has been recently described to participate in the mechanisms of iron-dependent cell death defined as "ferroptosis". Ferroptosis is a form of regulated cell death that is distinct from apoptosis, necroptosis, and other types of cell death. Ferroptosis has been shown to be associated with I/R injury and several other cardiac diseases as a significant form of cell death in cardiomyocytes. In this review, we will discuss the role of iron in cardiovascular diseases, especially in myocardial I/R injury, and protective mechanisms stimulated by different forms of "conditioning" with a special emphasis on the novel targets for cardioprotection.

Secondary forms of immune thrombocytopenia (ITP) represent approximately 20% of all ITP cases in adulthood and this rate increases with age. Since some causes may influence both the prognosis and outcome but also the management of ITP, a minimal workup must be performed at ITP diagnosis to look for an associated or underlying cause. Among adults, B-cell lymphomas and mainly chronic lymphocytic leukemia, systemic auto-immune diseases such as systemic lupus or primary immunodeficiencies mainly represented by common variable immunodeficiency are the most frequent causes of secondary ITP. Whereas first-line therapy used for secondary ITP is usually similar to the one commonly used in primary ITP and relies mostly on corticosteroids±intravenous immunoglobulin according to the severity of bleeding, second and third-line treatments must take into account the type and degree of activity of the underlying disease.Myelodysplastic syndromes (MDS) are clonal hematopoietic malignancies which are also characterised by immune dysregulation. The impaired immune response is mainly due to T lymphocytes (CD8 and T regulatory cells) with increased cell apoptosis. MDS could be associated in some cases with various clinical dysimmune features; however, only MDS with trisomy 8 is correlated with particular clinical phenotype. The latter is mainly Behçet's-like disease which includes orogenital aphtosis, skin features and severe ulcerative digestive disease of ileocaecal distribution. Other clinical manifestations, such as arthritis or neutrophilic dermatosis, have been also described in MDS patients with trisomy 8. The dysimmune manifestations, and among them the Behçet's-like disease, do not impact the overall survival or the risk of progression to acute myeloid leukemia. Immunosuppressive and immunomodulatory therapies, and among them TNF-α inhibitors, are usually ineffective to control the dysimmune manifestations. Targeting the underlying clonal disease with specific therapies, such as azacitidine, seems to be the best strategy to control these disorders, even in MDS patients with low-risk disease. To translate and culturally adapt the Patient and Observer Scar Assessment Scale, POSAS, to Norwegian and explore its test-retest, intra- and inter-tester reliability. POSAS was translated into Norwegian following international guidelines in collaboration with an international translation bureau. Twenty-six adults and 24 children were recruited from a burns outpatient clinic. Three observer-categories doctor, nurse and physiotherapist, assessed the patients' scars and scored the Observer scale for estimating inter-tester reliability. Photos of the scars were taken and used to score the Observer scale a second time for examining intra-tester reliability. The patients or parents/next of kin rated their scar on the Patient scale at the clinic and after two days at home for examining test-retest reliability. Intraclass correlation (ICC) and Kappa were used for statistical analysis. A Norwegian version of POSAS (POSAS-NV) was developed. Inter-tester ICC of the Observer parameters varied between 0.203 and 0.728, and for the total sum score, ICC=0.528 (0.280-0.708). Intra-tester ICC of the Observer scale ranged between 0.575 and 0.858. The Patient scale demonstrated high test-retest reliability. Intra-tester reliability of the Observer scale and test-retest reliability of the Patient scale of POSAS-NV were found satisfactory, but not inter-tester reliability of the Observer scale. Intra-tester reliability of the Observer scale and test-retest reliability of the Patient scale of POSAS-NV were found satisfactory, but not inter-tester reliability of the Observer scale.Proteins mediate many essential processes of life to a degree of functional precision unmatched by any synthetic device. While engineered proteins are currently used in biotech, food, biomedicine, and material technology-based industries, the true potential of proteins is practically untapped. https://www.selleckchem.com/products/piceatannol.html The emerging field of in silico protein design is predicted to provide the next quantum leap in the biotech industry. Having predictive control over protein function and the ability to redefine these functions have driven the field of protein engineering into an era of unprecedented development. This article provides a holistic analysis of protein design R&D (current state-of-the-art tools and knowhow) and commercial landscape, as well as a one-stop-shop profile of in silico protein design technology for biotechnology stakeholders.Most biopharmaceutical formulations use polysorbates surfactants that are highly efficient but difficult to manage in terms of compositional variability, quality, and stability. Alternatives, such as poloxamers, albumin, and cyclodextrin, are becoming popular and are being explored for their potential to protect biopharmaceuticals against physical and mechanical stresses.This study assessed if any herpes simplex virus (HSV) infection was a genetically valid target for late-onset Alzheimer's disease (AD) using 2-sample Mendelian randomization. We applied strong (p-value less then 5×10-6) and independent (r2 less then 0.05) genetic variants for any HSV infection (n = 450,581) to genome wide association studies of cognitive function (n = 300,486), and late-onset AD (n = 455,258) to obtain estimates. Genetically predicted log odds of any HSV infection was not associated with cognitive function (mean difference 0.0004 per any HSV infection, 95% confidence interval (CI) -0.001 to 0.001), or late-onset AD (odds ratio (OR) 0.999, 95% CI 0.998-1.001). Different genetic variant selections produced similar results. Any HSV infection does not appear to be a genetically valid target of intervention in late-onset AD, suggesting a rethink of the relevance of any HSV infection to late-onset AD.The emergence of near-infrared-II (NIR-II) activated photomedicines has extended the penetration depth for noninvasive theranostics, especially for photothermal nanomedicines. The current early development stage for NIR-II activated photomedicines has focused on creating a greater variety of photothermal agents (PTAs) with superior photothermal conversion ability. However, there is no thorough review for NIR-II inorganic PTAs and most comparisons of the photothermal performances of NIR-II inorganic PTAs are made with NIR-I PTAs. This review will first discuss about the key mechanisms of NIR-II absorption and photothermal conversion. Subsequently, this review will summarize recently developed advanced NIR-II inorganic PTAs based on the dominant inorganic elements and provide a comparison of their NIR-II photothermal performances. The nanostructure design, enhancement strategies and potential biomedical applications will be listed and discussed. We hope this review will further inspire active development and study of NIR-II activated inorganic PTAs with good photothermal conversion ability, multifunctionality, biocompatibility or biodegradability, and disease targeting ability.

titis with geographic ulceration and neurotrophic keratopathy and (2) offer objective measurements to guide management with topical corticosteroids until resolution of stromal edema. Thus, treatment can be initiated in a timely manner, and the blinding complications of HSV stromal keratitis can be avoided. The impact of residency training on academic productivity and a career in academic plastic surgery remains uncertain. Previous literature has explored the influence of training institutions on academic careers in surgery. The aims of the study were to assess research productivity during plastic surgery residency training and to illustrate how differences in training programs impact resident research productivity. Academic plastic surgery faculty that graduated in the past 10 years were identified through an Internet search of all Accreditation Council for Graduate Medical Education-accredited residency and fellowship training programs. Research productivity was compared based on h-index, number, and quality of peer-reviewed articles published during residency. Three hundred seventy-five academic plastic surgeons were identified and produced 2487 publications during residency. The 10 most productive training institutions were Johns Hopkins, Georgetown, University of Michigan, Stanford, University of Caliidents, recent graduates, and programs that are larger in size, with a higher Doximity ranking and NIH funding. This study can guide medical students and future applicants who are interested in a career in academic plastic surgery in the selection of programs that match their career aspirations. Our study has found that there is an elite cohort of programs that are the most productive research institutions. Resident research productivity is higher among integrated residents, recent graduates, and programs that are larger in size, with a higher Doximity ranking and NIH funding. This study can guide medical students and future applicants who are interested in a career in academic plastic surgery in the selection of programs that match their career aspirations. The limited supply of academic plastic surgery positions has led to increased demand and strong competition for these desired positions. Residents and students now seek out academic opportunities earlier in their training to account for this employment shortage. Training pathways and locations play an extremely important role in obtaining an academic position at most institutions. This study aimed to evaluate the training patterns of academic plastic surgeons in an attempt to elucidate its value and role for trainees interested in pursuing future academic careers. All full-time faculty members at currently accredited integrated and independent plastic surgery programs were included in the study; clinical affiliates were excluded. These institutions' websites were then queried to obtain the training history of the surgeons meeting inclusion criteria. Data were entered into a centralized database from which descriptive statistics were obtained. In the 741 surgeons included in the study, 514 (69.4%) complensidering an academic career should consider these patterns when planning their future careers.Ring avulsions continue to be a challenge in reconstructive surgery. We conducted a retrospective study and reviewed all Urbaniak-Kay type IV degloving injuries replanted at our institution between 2011 and 2018. A systematic review of the literature was also conducted to assess the survival rates, functional, and sensibility outcomes. The results of our systematic review outline a survival rate of 79.50% (101/127). With 1 artery being repaired, 79% of the fingers survived, a value that increased to 87.50% when 2 arteries were anastomosed (P = 0.484). Statistically significant differences (P less then 0.001) were found when comparing the survival rates of the fingers with 2 or more veins repaired (87%) with those with only 1 vein anastomosed (51.90%). In terms of nerve reconstruction, there was a significant difference (P less then 0.001) with the 2-point discrimination test in favor of the reconstructed group when nerve reparation was done (10.80 mm ± 2.95 mm) versus when digital nerves were not repaired (15.25 mm ± 0.50 mm). Fingers after secondary procedures did not obtain better mobility. The mean total active motion in nonreoperated fingers was 221 degrees (195-270 degrees), whereas the total active motion in the cases who received secondary surgeries was 152 degrees (110-195 degrees), with statistically significant differences (P = 0.02). Therefore, we recommend attempting replantation of degloved fingers. All efforts must be done to carry out 2 vein anastomoses, and our results strongly recommend attempting at least some kind of nerve reconstruction. https://www.selleckchem.com/products/ly2157299.html Secondary surgeries should be reserved for selected cases only, because of the extensive scarring in this kind of injuries. Early mobilization protocols must be encouraged to achieve a good functional result. Large skull reconstruction, with the use of customized cranial implants, restores cerebral protection, physiologic homeostasis, and one's preoperative appearance. Cranial implants may be composed of either bone or a myriad of alloplastic biomaterials. Recently, patient-specific cranial implants have been fabricated using clear polymethylmethacrylate (PMMA), a visually transparent and sonolucent variant of standard opaque PMMA. Given the new enhanced diagnostic and therapeutic applications of clear PMMA, we present here a study evaluating all outcomes and complications in a consecutive patient series. A single-surgeon, retrospective, 3-year study was conducted on all consecutive patients undergoing large cranioplasty with clear PMMA implants (2016-2019). Patients who received clear PMMA implants with embedded neurotechnologies were excluded due to confounding variables. All outcomes were analyzed in detail and compared with previous studies utilizing similar alloplastic implant materials. Fifty-five pativaluate long-term outcomes. Board-certified hand surgeons undergo an additional 1 year of fellowship training after completing 1 of 3 residencies, either orthopedic surgery (OS), plastic surgery (PS), or general surgery (GS). The purpose of our study was to examine primary care physician's referral patterns for hand surgery in the Southeastern United States. Primary care physicians across 38 academic medical institutions in the Southeastern United States were queried. A survey questionnaire was sent to their corresponding email address. The Questionnaire allowed the surveyor to enter demographic information and their choice in referral, either to OS, PS, or GS, for each particular hand pathology. Two-hundred twenty-eight of 1526 surveys were completed (15% response rate). One-hundred twenty-four were male respondents, and 105 were female. For treatment of arthritis, 94.7% selected OS; 5.3%, PS; and 0%, GS. For treatment of nerve decompression, 84.0% selected OS; 14.4%, PS; and 1.6%, GS. For treatment of nerve injuries, 64.2% selected OS; 34.

Further, we provide evidence that tumor progression depends on T-B cross talk facilitated by SAP and high-affinity LFA-1. In our study, AITL-like tumors relied heavily on molecular pathways that support Tfh cell identity and T-B collaboration, revealing potential therapeutic targets for AITL. © 2020 by The American Society of Hematology.Despite achieving a hematologic complete response after treatment, many patients with AL amyloidosis do not attain recovery of organ function and/or experience hematologic relapse. A persistent plasma cell clone producing amyloidogenic light chains at levels below the detection threshold of traditional serologic methods is hypothesized to impede organ response in some patients. Assessment of minimal residual disease (MRD) may therefore have clinical importance as a more stringent treatment response tool for patients in a hematologic complete response. We used 2-tube, 10-color combination multiparametric flow cytometry to assess for MRD at a minimum sensitivity of 1 in 105 nucleated cells. Of 65 patients in hematologic complete response, 36 (55%) were found to have a residual clonal plasma cell population in the bone marrow. Comparing the MRD-negative and MRD-positive groups, renal response was observed in 88% vs 64% (P = .06), cardiac response in 75% vs 59% (P = .45), and any organ response in 90% vs 75% (P = .20) of patients. Depth of organ response as measured by the percent decrease in 24-hour proteinuria and brain natriuretic peptide was 96% vs 91% (P = .16) and 55% vs 46% (P = .66), respectively. These data suggest a possible correlation between MRD negativity and higher probability of organ response after treatment in AL amyloidosis. Future prospective studies with a larger cohort are needed to determine the clinical relevance of these improvements. This trial was registered at www.clinicaltrials.gov as #NCT00898235. © 2020 by The American Society of Hematology.BACKGROUND High-mobility group box 1 (HMGB1) is one of the delayed pro-inflammatory cytokines produced in the later stages of pathogenesis and plays an important role in the progression of various inflammatory and autoimmune diseases. High-mobility group box 1 is able to stimulate interaction between integrins and cell adhesion molecules to facilitate cell-cell aggregation in "tissue-specific" endothelium; however, whether and how HMGB1 affects the adhesive capability of early acting immune cells in bloodstream remains largely unknown. METHODS Human peripheral blood samples were collected from healthy adult donors. The CD4 T cells were isolated from blood using CD4 T cell isolation kit and identified using flow cytometry and immunofluorescence staining. The effect of HMGB1 on adhesive ability of CD4 T cells was accessed by cell self-aggregation assay and endothelial adhesion assay. The migratory ability of CD4 T cells was evaluated by cell migration assay. Secretion of pro-inflammatory cytokines or chemokine proof of concept that HMGB1 promotes CD4 T cell self-aggregation before homing to inflammatory sites and highlight the potential of blocking immune cell self-aggregation in blood as a novel therapeutic approach against the development and progression of HMGB1-related inflammatory diseases.HMGB1 induces CD4 T cell self-aggregation in blood resulting in upregulation of integrins expression and release of pro-inflammatory cytokines/chemokines via activation of STAT3 signaling. https://www.selleckchem.com/products/indy.html This study highlights the potential of preventive and therapeutic intervention on immune cell self-aggregation in the bloodstream. © 2020 Crohn’s & Colitis Foundation.

METHODS We performed factorial analyses and generalized linear models with CAPE scores as the dependent variable in a sample composed of 217 first-episode psychosis patients, 104 unaffected biological siblings, and 319 non-psychotic population-based participants. RESULTS After removing seven items from its positive dimension and two items from its negative dimension, a 33-item Brazilian version of the CAPE showed acceptable adjustment indices (confirmatory fit index = 0.895; goodness of fit index = 0.822; parsimony goodness of fit index = 0.761; root mean square error of approximation [RMSEA] = 0.055, p [RMSEA ≤ 0.05] = 0.04) and internal consistency in all its dimensions (> 0.70). Childhood adversity was associated with higher scores in all three dimensions, as well as with total score. Lifetime cannabis use was associated with higher scores only in the positive dimension. CONCLUSION The proposed Brazilian version of the CAPE corroborates the tridimensional approach for assessing psychosis-proneness, and the frequency and severity of psychotic manifestations are distributed as a spectrum in the general population.OBJECTIVE The aim of this study was to understand the knowledge, beliefs, barriers, and behaviors of mental health professionals about physical activity and exercise for people with mental illness. METHODS The Portuguese version of The Exercise in Mental Illness Questionnaire was used to assess knowledge, beliefs, barriers, and behaviors about exercise prescription for people with mental illness in a sample of 73 mental health professionals (68.5% women, mean age = 37.0 years) from 10 Psychosocial Care Units (Centros de Atenção Psicossocial) in Porto Alegre and Canoas, state of Rio Grande do Sul, Brazil. RESULTS Most of respondents had received no formal training in exercise prescription. Exercise ranked fifth as the most important treatment, and most of the sample never or occasionally prescribed exercise. The most frequently reported barriers were lack of training in physical activity and exercise prescription and social stigma related to mental illness. Professionals who themselves met recommended physical activity levels found fewer barriers to prescribing physical activity and did so with greater frequency.
