The potato cyst nematodes (PCN), Globodera rostochiensis (Woll.) and G. pallida (Stone), are important pests of potato globally. Due to their extensive damage potential and the challenge of managing them, these nematodes are under strict regulations in many countries; however, despite these regulations, PCN continue to spread into new areas and countries. In Kenya, G. rostochiensis was first reported in 2015 and G. pallida was reported three years later, both in Nyandarua County. Research was conducted to characterize the biology, pathotype, and virulence of G. rostochiensis populations from Kenya in glasshouse and laboratory studies. The development of G. rostochiensis was assessed in roots of susceptible potato 'Désirée' and resistant 'Laura' carrying the H1 resistance gene. The 'HAR1' population from Kenya and 'Ecosse' from Germany were not able to produce females in the roots of the resistant potato 'Laura'. The rate of root penetration by G. rostochiensis juveniles did not differ (p > 0.05) between popul H1 resistance gene.This contribution provides the morphological and molecular identification of a new species of the genus Longidorella (Saevadorella). L. (S.) caspica n. sp., was recovered from the rhizospheric soil of grasses in Mazandaran province in the seashore of the Caspian Sea. It is characterized by females with a length of 788 to 874 μm and a cephalic region with prominent papillae; and separated from the rest of the body by a remarkable constriction, an odontostyle of 32 to 33 μm, vulva at 52.5 to 59.0%, and a tail of 33 to 38 μm with a rounded tip. Males have 32 to 35 μm long spicules of dorylaimoid form and five to seven ventral supplements ending at 48 to 55 μm distance from cloacal pair. The new species was morphologically compared with seven nominal species viz. L. (S.) arenicola, L. (S.) cuspidata, L. (S.) magna, L. (S.) perplexa, L. (S.) saadi, L. (S.) saevae, and L. (S.) tharensis. It was further compared with similar species under the subgenus Longidorella (Enchodorella) viz. L. (E.) deliblatica and L. (E.) murithi. Besides morphological studies, molecular phylogenetic studies using partial sequences of D2 to D3 expansion fragments of 28S rDNA were performed for the new species and its phylogenetic relationships with other species and genera were discussed.The microbial loop has been suggested as an alternative route for better utilization of phytate, a poorly available P source to plants. We hypothesized that bacterial grazer activity might dramatically enhance bacterial migration and proliferation, increasing the probability of phytate hydrolysis by bacterial phytases and, thus, phytate mineralization and release of free phosphate. We tested this hypothesis in a two-compartment system with a solid medium containing phytate or free phosphate as the source of P. Two bacterial species, B. subtilis 168 or Bradyrhizobium sp., with or without bacterial grazing nematodes belonging to Acrobeloides sp. previously fed on each of the bacterial species, were inoculated at a single point in the medium. Whatever the P source, nematode migration within both zones allowed the proliferation of bacteria. However, B. subtilis 168 was more efficient in using phytate than Bradyrhizobium sp. since the highest bacterial cell density and free phosphate concentrations were reached by Acrobeloides sp. fed on B. https://www.selleckchem.com/autophagy.html subtilis 168. The grazer activity seemed to be crucial to enhance phytate mineralization, despite Acrobeloides sp. showing a higher preference to feed on Bradyrhizobium sp. This study provides new insights into the effects of bacterial grazer activity on phytate mineralization.During a survey on the biodiversity of plant-parasitic nematodes of natural areas in Botswana, Mesocriconema sphaerocephalum was discovered around the rhizosphere of the wild grass. The nematodes were extracted using the tray method and then fixed according to the available protocols. The morphological characters fit well with the M. sphaerocephalum. Besides, molecular aspects using 18S and 28S rDNA were studied. The phylogenetic analysis of 18S and 28S rDNA placed the examined population with other populations of M. sphaerocephalum in a group. According to the knowledge, this is the first report of M. spaherocephalum from Botswana.Ginger (Zingiber officinale Roscoe) and long coriander (Eryngium foetidum L.) are commonly grown and used as important spices and medicinal plants in Vietnam. Our study recovered for the first time one of the most damaging tropical root-knot nematodes, Meloidogyne javanica, associated with these plants in the Western Highlands of Vietnam. In this study, M. javanica was characterized based on morphology and molecular characterization of D2-D3 fragment of 28S rRNA, ITS, and Nad5 mtDNA regions. The identification of this species was done based on a combination of morphology, multiplex-PCR with specific primer, network haplotype analysis, and PPNID program.Two populations of a Butlerius species were recovered from compost in two gardens in Potchefstroom, North-West Province, South Africa. Although the genus has previously been reported from South Africa, no species of the genus has ever been identified in the country. Based on morphological, morphometric, and molecular studies, the specimens were identified as Butlerius butleri and are herein reported for the first time from South Africa. The South African specimens are 1,082 to 1,423 µm long, a = 40.8 to 47.6; b = 4.7 to 5.8; c = 4.0 to 6.0; c' = 117 to 16.3; V = 44 to 47%. Cuticle with evenly spaced punctations. Reproductive system didelphic, amphidelphic, both branches equal in length. Four large glands opening into proximal part of uterus. Males with prominent sphincter present in mid-region of vas deferens. Spicules 36 to 43 μm long, gubernaculum 23 to 31 µm long, nine pairs of genital papillae, three pre-cloacal and six post-cloacal, formula v1, v2, v3d/v4, ad, ph, v5, 6, 7, pd. The v5, 6, 7 clusters greatly separated, left subventral group at level of phasmid, right subventral group at level of posterior dorsal papilla. Although there were some differences, the South African populations of the species compare well to all know descriptions of the species. Phylogenetic analysis based on partial small subunit (SSU) rDNA sequences showed that both South African populations of B. butleri are in a maximally supported sister relation with an Iranian population of this species. Based on large subunit (LSU) rDNA sequences, the two populations of B. butleri clustered together in a well-supported clade.

VA creation and interventions maintain the lifeline of complex HD patients, and the indication for surgery and other interventions warrants patient-specific clinical judgement and pathways. Keeping the use of central venous catheters at a minimum, with the goal of creating the right access, in the right patient, at the right time, and for the right reasons, is mandatory. These strategies may require local modifications. Risk assessments may need specific "renal pathways" to be developed rather than applying standard surgical risk stratification. In conclusion, in order to recover from the second wave of COVID-19 and prepare for further phases, the provision of the best dialysis access, including peritoneal dialysis, will require working closely with the multidisciplinary team involved in the assessment, creation, cannulation, surveillance, maintenance, and salvage of definitive access. Erectile dysfunction, which has been associated with mortality in the general population, is common in individuals on hemodialysis. Our aim was to determine the relationship between erectile dysfunction, coronary artery calcification and mortality in incident hemodialysis patients. A prospective cohort of incident adult dialysis patients with no history of coronary artery disease underwent coronary artery calcification measurement by ECG-triggered multi-slice computed tomography (MSCT) scan at baseline and at least 12months later. Erectile dysfunction was determined using the 15-item validated International Index of Erectile Function (IIEF-15) questionnaire. Erectile dysfunction was prevalent in 83% of patients, with 43% classified as severe erectile dysfunction, 22.4% as moderate erectile dysfunction, and 17.2% as mild erectile dysfunction. The median (IQR) coronary artery calcification score was 43.4 (0.25-353.8) for those with erectile dysfunction and 0 (0-0) for those without erectile dysfunction (pory of coronary artery disease. Hepatitis B virus (HBV) infections are associated with an increased risk of kidney diseases. However, the effects of HBV infection on the prognosis of immunoglobulin A nephropathy (IgAN) are unclear. A total of 838 patients with biopsy-confirmed IgAN were enrolled in this retrospective cohort study. https://www.selleckchem.com/products/p22077.html The patients were categorized into either affected byIgAN and HBV infection (HBsAg-IgAN) or byprimary IgANwith no sign of HBV infection (P-IgAN). A 11 propensity-score matching was performed between the twogroups, followed by a Kaplan-Meier survival analysis, to compare the prognoses, and a Cox regression analysis, to identify factors influencing the HBsAg-IgAN outcomes. A total of 176 pairs of patients were successfully matched. A significant difference in the systolic blood pressure and urea, serum creatinine, uric acid, and 24-h urine protein levels was observed between the groups. A renal pathological analysis also revealed a significant difference in the mesangial hypercellularity between the groups. During a median follow-up period of 2.4years, Kaplan-Meier analysis also revealed a significant difference in the renal survival between the groups. Furthermore, multivariate Cox analysis confirmed that HBV infection is an independent risk factor for IgAN progression (hazard ratio [HR] 2.096; 95% confidence interval [CI] 1.091-4.026). Finally, the HBsAg-IgAN patients who received treatment with renin-angiotensin-aldosterone system inhibitors had a better overall prognosis than those who received immunosuppressive therapy and antiviral treatment. Our results indicate that the clinicopathological features and outcomes of patients with IgAN differ significantly between those with and without HBV infection, and that HBV is an independent risk factor for IgAN progression. Our results indicate that the clinicopathological features and outcomes of patients with IgAN differ significantly between those with and without HBV infection, and that HBV is an independent risk factor for IgAN progression. Robust experimental data for performing validation of fluid-structure interaction (FSI) simulations of the transport of deformable solid bodies in internal flow are currently lacking. This in vitro experimental study characterizes the clot trapping efficiency of a new generic conical-type inferior vena cava (IVC) filter in a rigid anatomical model of the IVC with carefully characterized test conditions, fluid rheological properties, and clot mechanical properties. Various sizes of spherical and cylindrical clots made of synthetic materials (nylon and polyacrylamide gel) and bovine blood are serially injected into the anatomical IVC model under worst-case exercise flow conditions. Clot trapping efficiencies and their uncertainties are then quantified for each combination of clot shape, size, and material. Experiments reveal the clot trapping efficiency increases with increasing clot diameter and length, with trapping efficiencies ranging from as low as approximately 42% for small 3.2mm diameter spherical clots up to 100% for larger clot sizes. Because of the asymmetry of the anatomical IVC model, the data also reveal the iliac vein of clot origin influences the clot trapping efficiency, with the trapping efficiency for clots injected into the left iliac vein up to a factor of 7.5 times greater than that for clots injected into the right iliac (trapping efficiencies of approximately 10% versus 75%, respectively). Overall, this data set provides a benchmark for validating simulations predicting IVC filter clot trapping efficiency and, more generally, low-Reynolds number FSI modeling. Overall, this data set provides a benchmark for validating simulations predicting IVC filter clot trapping efficiency and, more generally, low-Reynolds number FSI modeling.Although the adverse effects of non-essential heavy metals on semen quality have been demonstrated in experimental animal models and occupational human exposure studies, little is known about the reproductive efficiency of exposed sperm during the process of intracytoplasmic sperm injection (ICSI). Our study aims to evaluate the effect of paternal exposure to non-essential heavy metals on embryo efficiency outcomes (embryo cleavage, fragmentation, implantation, and live birth) in ICSI cycle. Ninety-five heterosexual couples who underwent 95 ICSI cycles and 78 fresh embryo transfers between January 2003 and December 2009 were evaluated. Men whose female partner was undergoing ICSI were asked to provide semen and blood samples. Heavy metal levels (Pb, Cd, As, Hg, Ba, and U) were analyzed using an ion-coupled plasma-mass spectrometry (ICP-MS; Agilent 7500 ce, Agilent Technologies, Germany) equipped with a cell dynamic range (CDR). Paternal exposure to trace heavy metals was found to influence intermediate reproductive endpoints in ICSI cycles.

Randomized controlled trials have shown that screening with computed tomography reduces lung cancer mortality but is most effective when applied to high-risk individuals. Accurate lung cancer risk prediction models effectively select individuals for screening. Few pilots or programs have implemented risk models for enrolling individuals for screening in real-world, population-based settings. This report describes implementation of the PLCOm2012 risk prediction model in the Ontario Health (Cancer Care Ontario) lung cancer screening Pilot. In the Pilot's Health Technology Assessment, 576 categorical age/pack-years/quit-years scenarios were evaluated using MISCAN microsimulation modeling and cost-effectiveness analyses. A preferred model was selected which provided the most life-years gained per cost. The PLCOm2012 was compared to the preferred MISCAN scenario at a threshold that yielded the same number eligible (risk ≥2.0 %/6-years). The PLCOm2012 had significantly higher sensitivity and predictive value he PLCOm2012 can lead to effective and efficient screening.Cannabidiol (CBD) is a marijuana compound implicated in epilepsy treatment in animal models and pharmacoresistant patients. However, little is known about chronic CBD administration's effects in chronic models of seizures, especially regarding its potential antiepileptogenic effects. In the present study, we combined a genetic model of epilepsy (the Wistar Audiogenic Rat strain - WARs), a chronic protocol of seizures (the audiogenic kindling - AuK), quantitative and sequential behavioral analysis (neuroethology), and microscopy imaging to analyze the effects of chronic CBD administration in a genetic model of epilepsy. The acute audiogenic seizure is characterized by tonic-clonic seizures and intense brainstem activity. However, during the AuK WARs can develop limbic seizures associated with the recruitment of forebrain and limbic structures. Here, chronic CBD administration, twice a day, attenuated brainstem, tonic-clonic seizures, prevented limbic recruitment, and suppressed limbic (kindled) seizures, suggesting CBD antiepileptogenic effects. Additionally, CBD prevented chronic neuronal hyperactivity, suppressing FosB immunostaining in the brainstem (inferior colliculus and periaqueductal gray matter) and forebrain (basolateral amygdala nucleus and piriform cortex), structures associated with tonic-clonic and limbic seizures, respectively. Chronic seizures increased cannabinoid receptors type 1 (CB1R) immunostaining in the hippocampus and the BLA, while CBD administration prevented changes in CB1R expression induced by the AuK. The neuroethological analysis provided details about CBD's protective effects against brainstem and limbic seizures associated with FosB expression. Our results strongly suggest chronic CBD anticonvulsant and antiepileptogenic effects associated with reduced chronic neuronal activity and modulation of CB1R expression. We also support the chronic use of CBD for epilepsies treatments. Many children live with parents who drink and experience little impact, but risky or heavy drinking by caregivers can result in a range of harms to children. Alcohol-related financial harms which directly impact children's needs in general populations have been seldom studied. The study aims to identify the prevalence and correlates of financial harms from others' drinking affecting children's needs in nine lower- and middle-income (LMICs) and high-income countries (HICs). Participants (n=7,669) from Brazil, Chile, Ireland, Lao PDR, Nigeria, Sri Lanka, Thailand, USA and Viet Nam were aged 18-64 years and living with children. Logistic regression and meta-analyses explored differences in financial harm affecting children among LMICs and HICs, adjusting for gender, education, rurality and drinking pattern. In around one-tenth to a third of households in the nine countries, children lived with people who drank riskily. Less than 1% to 8% of respondents reported that their children's needs had not been me across the nine countries, representing a problem for large numbers of children, particularly in the low and middle-income countries studied. When a person's drinking was reported to be heavy or harmful within the family, the risk that children's needs were affected by the financial impacts of others' drinking was significantly greater. Minimally invasive pancreaticoduodenectomy (MIPD), including laparoscopic pancreaticoduodenectomy (LPD) and robotic pancreaticoduodenectomy (RPD), is technically demanding because of pancreaticojejunostomy (PJ). Postoperative pancreatic fistula (POPF) is the most serious complication of MIPD and open pancreaticoduodenectomy (OPD). Contrary to expectations, conventional PJ in MIPD did not improve POPF rate and length of hospital stay. High POPF rates are attributed to technical issues encountered during MIPD, which include motion restriction and insufficient water tightness. Therefore, we developed wrapping double-mattress anastomosis, the Kiguchi method, which is a novel PJ technique that can improve MIPD. Herein, we describe the Kiguchi method for PJ in MIPD and compare the outcomes between this technique and conventional PJ in OPD. The current retrospective study included 83 patients in whom the complete obstruction of the main pancreatic duct by pancreatic tumors was absent on preoperative imaging. https://www.selleckchem.com/products/deferoxamine-mesylate.html Thiced the POPF rate in patients without complete obstruction of the main pancreatic duct. Mounting evidence points to a substantial link between detailed media portrayals of suicide and imitative suicidal behaviour. We assessed the quality of media reporting of suicide in Kerala, a high suicide burden state in India against the World Health Organization (WHO) reporting guidelines. We conducted a year-round content analysis of all suicide-related news articles in four (two local language and two English) of the most widely read daily newspapers in Kerala. We used a data extraction form, prepared a priori in accordance with the WHO reporting checklist, and coded each item based on the guidelines. A total of 377 suicide news articles were retrieved. Harmful reporting practices such as reporting the name (93.9 %) and age (93.6 %) of the deceased, method of suicide (93.1 %), location of suicide (88.9 %), monocausal explanations (48.8 %), and including photograph of the deceased (37.7 %) were commonly noted. On the other hand, less than a fifth of articles complied with helpful practices such as including details of suicide support helpline (19.

To describe the anatomic and technical highlights of a novel nerve-sparing surgery in deep endometriosis (DE) using near-infrared (NIR) fluorescence technology and indocyanine green (ICG). Stepwise demonstration of this method with narrated video footage. An urban general hospital. A 48-year-old woman was referred for severe chronic pelvic pain, dysmenorrhea, and pain on defecation, all of which were resistant to medication therapy. Magnetic resonance imaging revealed uterine adenomyosis and left ovarian endometrioma with DE involving the uterosacral ligament, posterior cervix, and surface of the rectum, with complete cul-de-sac obliteration. An intravenous injection of 0.25 mg/kg body weight of ICG for intraoperative NIR fluorescence imaging. https://www.selleckchem.com/products/at13387.html Ethics approval was obtained from the institutional review board at our hospital (IRB No. 985). Evaluation of blood perfusion of DE nodule and achieving better visualization of anatomic relationship to the pelvic autonomic nerves. The procedure was performe. Furthermore, the hypogastric nerve and inferior hypogastric plexus were strongly highlighted by ICG and objectively preserved with the assessment of perfusion. The patient developed no perioperative complications, including postoperative bladder or rectal dysfunction after surgery. To our knowledge, this is the first reported use of ICG during nerve-sparing surgery for gynecologic disease. Application of ICG with NIR fluorescence appears potentially useful, not only to remove DE, but also to improve nerve-sparing.

The relationship between child-to-adult blood pressure (BP) trajectories and metabolic syndrome (MetS) is unknown. We aimed to determine the predictive role of BP trajectories for incident MetS and its components. The prospective Hanzhong Adolescent Hypertension study began in 1987 and included 2692 participants free of MetS at baseline with at least 3 BP measurements available from 1987 to 2017. The systolic BP (SBP) trajectory patterns were grouped as normal (class 1, 18.7%), high normal (class 2, 60.3%), prehypertensive (class 3, 13.1%), stage 1 hypertensive (class 4, 5.7%), and stage 2 hypertensive (class 5, 2.2%). Compared with those in the normal group, individuals in classes 2 to 5 had significantly higher risks of MetS (all Ps < .05), and those with hypertension had more than an 8-fold higher risk of MetS (both P < .05). The fully adjusted risk ratios (RRs) of central obesity increased significantly in a stepwise manner as the SBP trajectory group increased from class 1 to class 5 (P < .05). Compared with those with a normal SBP trajectory, participants in the prehypertensive group and stage 1 and stage 2 hypertensive groups had significantly higher RRs for high-risk triglycerides after full adjustment (RR= 1.89 [1.22-2.94]; RR= 3.61 [2.16-6.02]; and RR= 3.22 [1.52-6.84], respectively). Our study suggests that BP trajectories are predictive of incident MetS outcomes. Early detection of hypertension or modest elevations in BP is crucial. The stage of hypertension based on SBP level showed a greater association with central obesity. Our study suggests that BP trajectories are predictive of incident MetS outcomes.

Large well-differentiated hepatocellular carcinoma (HCC)≥3cm (defined as atypical HCC) is uncommon. We evaluated the characteristics and outcomes of atypical HCC patients underwent liver resection (LR). This retrospective study enrolled patients who underwent LR for HCC from 2007 to 2017. Patient characteristics and overall survival (OS) were compared between patients with atypical HCC and patients with typical HCC (moderate-to-undifferentiated HCC≥3cm). Among 598 patients, 51 (8.5%) had atypical HCC. Patients with atypical HCC had higher rates of non-hepatitis B or C infections (p=0.02) and American Joint Committee on Cancer T1 pathology (p<0.001), a lower rate of alpha-fetoprotein >20ng/ml (p<0.001) and a longer OS (p<0.001) than those with typical HCC. Multivariate analysis showed that atypical HCC was associated with OS (HR=0.50, 95% CI=0.27-0.91, p=0.02). Patients with atypical HCC have a higher rate of non-hepatitis B or C infections and a lower rate of aggressive tumor biologic behavior. Atypical HCC is an independent predictor of OS.

Wire localized breast biopsy (WLB) is the most commonly performed procedure for the removal of non-palpable breast cancer. It is associated with patient discomfort and high re-excision rates. Intraoperative ultrasound (IOUS) is an alternative technique that may improve patient experience and have lower re-excision rates. A retrospective, single surgeon experience with IOUS is compared with WLB. Case matching for variables known to impact re-excision rates is performed. Fisher's exact test was performed for categorical variables, and a T-test for continuous variables. 28 patients underwent IOUS and WLB. Re-excision rates were the same in patients undergoing IOUS and WLB (10.7% vs 0%; p=0.24). The calculated resection ratio was lower with IOUS than WLB (2.99 vs 3.46; p=0.37), but did not reach statistical significance. In selected patients, intra-operative ultrasound can be performed with a favourable re-excision rate, and comparable amounts of tissue compared to wire localized breast biopsy.

Our aim was to examine differences in clinical outcomes between Hispanic subgroups who underwent emergency general surgery (EGS). Retrospective cohort study of the HCUP State Inpatient Database from New Jersey (2009-2014), including Hispanic and non-Hispanic White (NHW) adult patients who underwent EGS. Multivariable analyses were performed on outcomes including 7-day readmission and length of stay (LOS). 125,874 patients underwent EGS operations. 22,971 were Hispanic (15,488 with subgroup defined 7,331 - Central/South American; 4,254 - Puerto Rican; 3,170 - Mexican; 733 - Cuban). On multivariable analysis, patients in the Central/South American subgroup were more likely to be readmitted compared to the Mexican subgroup (OR 2.02; p<0.001, respectively). Puerto Rican and Central/South American subgroups had significantly shorter LOS than Mexican patients (Puerto Rico-0.58 days; p<0.001; Central/South American-0.30 days; p=0.016). There are significant differences in EGS outcomes between Hispanic subgroups.

Neonatal intrahepatic cholestasis with citrin deficiency (NICCD) results in coagulopathy due to decreased levels of vitamin (V)K-dependent clotting factors, similar to biliary atresia (BA). However, the involvement of VK-independent coagulant and anticoagulant factor(s) remains unknown. To examine relationships between coagulant and anticoagulant potential, with addition to the influence of nutritional treatment, in NICCD. Three cases (aged 12, 21, and 45 days) with NICCD-associated coagulopathy were evaluated with standard coagulation/anticoagulation tests and comprehensive coagulation assays, rotational thromboelastometry (ROTEM), and protein C/protein S (PC/PS) pathway function assay (ThromboPath ), before and after nutritional treatment. In all cases, activated partial thromboplastin time and prothrombin time were significantly prolonged associated with very low levels of VK-independent fibrinogen and antithrombin. The initiation of nutritional treatment of medium-chain triglycerides oil had impulant and anticoagulant potential involving low levels of fibrinogen and antithrombin, suggesting the pathophysiological coagulopathy distinct from BA.Biosynthesis of (1R,4aS,7S,7aR)-nepetalactol (1) and (4aS,7S,7aR)-nepetalactone (2) in plants involves iridoid synthase (ISY), an atypical reductive cyclase that catalyses the reduction of 8-oxogeranial into the reactive enol of (S)-8-oxocitronellal, and cyclization of this enol intermediate, either non-enzymatically or by a nepetalactol-related short chain dehydrogenase enzyme (NEPS) that yields the nepetalactols. In this study, we investigated the biosynthesis in vivo of 1 and 2 in the pea aphid, Acyrthosiphon pisum, using a library of isotopically-labelled monoterpenoids as molecular probes. Topical application of deuterium-labelled probes synthesized from geraniol and nerol resulted in production of 2 H4 -lactol 1 and 2 H4 -lactone 2. However, deuterium incorporation was not evident using labelled probes synthesized from (S)-citronellol. These results suggest that iridoid biosynthesis in animals, specifically aphids, may follow a broadly similar route to that characterised for plants. Lateral skull base tumors often necessitate temporal bone resection (TBR), although clinical outcomes can be unfavorable. Factors influencing survival and recurrence after TBR for cutaneous and salivary malignancies were evaluated. Twenty-six TBR subjects were included. Survival and recurrence outcomes were estimated at 1, 2, and 5 years postresection. Prognostic factors were analyzed using univariate and multivariate Cox regression. Two years postresection, the overall survival (OS), disease-specific survival (DSS) and recurrence-free survival (RFS) rates were 61%, 74%, and 49%, respectively, and 51%, 63%, and 45% at 5 years. On univariate analysis, preoperative facial nerve dysfunction and intraoperative nerve sacrifice worsened OS, DSS, and RFS. Prior surgery and adjuvant radiation independently predicted reduced OS, DSS, and RFS on multivariate analysis. Mortality is highest in the first 2 years following resection. Preoperative facial nerve dysfunction, facial nerve sacrifice, and prior radiation are negative predictors of survival and recurrence. Mortality is highest in the first 2 years following resection. Preoperative facial nerve dysfunction, facial nerve sacrifice, and prior radiation are negative predictors of survival and recurrence.A novel method is demonstrated to encapsulate titanium dioxide pigment using directed polymerization-induced self-assembly (PISA) with reversible addition-fragmentation chain-transfer (RAFT) controlled emulsion polymerization. The polymerization is carried out in a batch process in which both styrene (Sty) and the pigment are emulsified using triblock amphiphilic macro-RAFT copolymers as stabilizers. RAFT-controlled chain growth leads to directed lamellar self-assembly, forming polystyrene (PS) shells' encapsulating pigment particles with 100% efficiency. The pigment resides either at centers of single-void vesicles or within the interior of multivoid vesiculated particles. The presence of complex morphologies such as spherical particles, nanofibers, nanoplatelets, and polymer vesicles confirms the PISA pathway. The process is optimized to preferably produce polymer-vesiculated pigment for use as an enhanced opacifier in water-based paint.Alzheimer's disease can be diagnosed by analyzing brain images (eg, magnetic resonance imaging, MRI) and neuropsychological tests (eg, mini-mental state examination, MMSE). https://www.selleckchem.com/products/icec0942-hydrochloride.html A partially linear mean shift model (PLMSM) is here proposed to investigate the relationship between MMSE score and high-dimensional regions of interest in MRI, and detect the outliers. In the presence of high-dimensional data, existing Bayesian approaches (eg, Markov chain Monte Carlo) to analyze a PLMSM take intensive computational cost and require huge memory, and have low convergence rate. To address these issues, a variational Bayesian inference is developed to simultaneously estimate parameters and nonparametric functions and identify outliers in a PLMSM. A Bayesian P-splines method is presented to approximate nonparametric functions, a Bayesian adaptive Lasso approach is employed to select predictors, and outliers are detected by the classification variable. Two simulation studies are conducted to assess the finite sample performance of the proposed method. An MRI dataset with elderly cognitive ability is provided to corroborate the proposed method.Cognitive impairments are a part of the neurocognitive disorders which deteriorate the normal cognitive function. An overview of systematic reviews (SRs) was conducted to summarize the findings of SRs and meta-analyses on the effectiveness of Huperzine A (Hup A) in dementia and mild cognitive impairment (MCI). A literature search was conducted since inception to December 2020. We used the AMSTAR tool to assess the methodological quality of SRs. The quality of evidence of primary studies was evaluated according to the SRs authors' assessment. Six SRs met our inclusion criteria. The results showed that Hup A has beneficial effects on cognitive function and Activities of Daily Living (ADLs) in Alzheimer's disease, but in vascular dementia and MCI, there was little or no evidence to conclusion. There is insufficient evidence of the effectiveness of Hup A on the quality of life and global clinical assessment. None of the SRs reported any serious side effects. Despite the promising effects of Hup A on cognition and ADLs, there is insufficient evidence to support the effectiveness of Hup A in cognitive impairments due to the high heterogeneity of SRs and the low quality of primary studies.

Based on our previous study on the development of the furoquinolinedione and isoxazoloquinolinedione TDP2 inhibitors, the further structure-activity relationship (SAR) was studied in this work. A series of furoquinolinedione and isoxazoloquinolinedione derivatives were synthesized and tested for enzyme inhibitions. Enzyme-based assays indicated that isoxazoloquinolinedione derivatives selectively showed high TDP2 inhibitory activity at sub-micromolar range, as well as furoquinolinedione derivatives at low micromolar range. The most potent 3-(3,4-dimethoxyphenyl)isoxazolo[4,5-g]quinoline-4,9-dione (70) showed TDP2 inhibitory activity with IC50 of 0.46 ± 0.15 μM. This work will facilitate future efforts for the discovery of isoxazoloquinolinedione TDP2 selective inhibitors.In this work, a novel series of hydrazineylideneindolinone linked to phenoxymethyl-1,2,3-triazole derivatives were designed, synthesized, and evaluated for their anti-α-glucosidase activity due to an urgent need to develop effective anti-diabetic agents. Among tested 15 compounds, 8 derivatives (9a, 9b, 9c, 9d, 9e, 9f, 9h, and 9o) demonstrated superior potency compared to that of positive control, acarbose. Particularly, compound 9d possessed the best anti-α-glucosidase activity with around a 46-fold improvement in the inhibitory activity. Additionally, 9d showed a competitive type of inhibition in the kinetic study and the molecular docking study demonstrated that it well occupied the binding pocket of the catalytic center through desired interactions with residues, correlating to the experimental results.Building on our previous work that discovered chalcone as a promising pharmacophore for anticancer activity, we have various other chalcone derivatives and have synthesized a series of novel bischalcone to explore their anticancer activity. Among all tested compounds, compounds 6a, 6b, and 6c showed the highest antiproliferative activity against A-549 cancer cell lines with the average IC50 values of 4.18, 4.52, and 5.05 µM, respectively. Moreover, compound 6c showed high antiproliferative activity against the Caco-2 cell line; thus, it was 2- and 4-fold more active than the reference compounds, i.e., methotrexate and capecitabine. Compound 6a also induced cell-cycle arrest in the S phase, whereas compounds 6b and 6c were observed to stop at the G0/G1 phase. Thereafter, we evaluated that compound 6c also had the highest apoptosis/necrosis ratio than other compounds and the standard compound. The anticancer property of the 6c was also supported by molecular docking studies carried out on the EGFR and HER2 receptors. Overall, we expect that these compounds can be further developed for the potential treatment of lung cancer.Nine previously undescribed butyrolactone and sesquiterpene derivatives, named cyclopentanone A (1), subamolides F and G (2 and 3), secosubamolide F (4), rupestonic acids J - L (5-7), linderaguaianols A and B (8 and 9), together with six known ones 10-15 were isolated from the roots of Lindera glauca. Their structures, including their absolute configurations were elucidated by extensive spectroscopic analysis, quantum chemical calculations, and Mo2(AcO)4-induced circular dichroism. Compound 1 that possessed a unique five-membered cyclopentane skeleton with a side chain was rarely found from natural sources. The biogenetic pathway for 1-4 was postulated. Secosubamolide F (4) inhibited nitric oxide (NO) production in lipopolysaccharide (LPS)-activated RAW264.7 cells with IC50 value of 1.73 ± 0.18 μM and also significantly suppressed the production of iNOS. The binding interactions between 4 and iNOS were investigated using docking analyses.Immunotherapy via immune checkpoints blockade has aroused the attention of researchers worldwide. Inhibition of the programmed cell death-1 (PD-1)/programmed cell death-ligand 1 (PD-L1) interaction has been one of the most promising immunotherapy strategies. https://www.selleckchem.com/products/nutlin-3a.html Several neutralizing antibodies targeting this interaction have been developed, which have already achieved considerable clinical success. Additionally, numerous pharmaceutical companies have been committed to develop small molecules which could block the interaction between PD-1 and PD-L1. In this study, a novel PROTAC molecule 21a was developed, and effectively induced the degradation of PD-L1 protein in various malignant cells in a proteasome-dependent manner. Moreover, compound 21a could significantly reduce PD-L1 protein levels of MC-38 cancer cells in vivo, by which promoted the invasion of CD8+ T cells and inhibited the growth of MC-38 in vivo. This PROTAC molecule could be used as a novel and alternative strategy for cancer immunotherapy.Liver cancer is the most common type of cancer in many countries. New studies and statistics show rising liver cancer worldwide, so it is essential to seek new agents for this type of cancer. PIM1 has an attractive target in the discovery of cancer medications as it is very much expressed in a variety of malignancies and influences such as tumorigenesis, cell cycle progression, cellular proliferation, apoptosis, and cell migration. Accordingly, a series of pyridones and pyridine-amides were synthesized and tested for anti-liver cancer activity. In the synthetic strategy 4,6-diaryl-3-cyano-2-pyridones 3a-n were synthesized using one-pot four component synthetic method. Structural modifications were done on 4,6-diphenyl-3-cayno-2-pyridone 3a to enhance the activity. Alkylation in the presence of K2CO3 afforded the O-alkylated products 4-6. The acetoxy hydrazide 7 was synthesized and cyclized into 1,3,4-oxadiazolethione 8 which alkylated on sulfur to give 10. Azide-coupling method was used to couple the 2-(pyridin-2-yloxy)acetohydrazide 7 to different amines and amino acid esters to furnish the products 12a-e and 13a-b. The synthesized derivatives were subjected to cytotoxic screening against HepG2 and THLE-2 cells, Compounds 10, 12e and 13a have a remarkable cytotoxic activity with IC50 values (10.7-13.9 µM). Compound 7 was found to be more cytotoxic by showing the lowest IC50 value of 7.26 compared to 5-FU (IC50 = 6.98 µM). It inhibited cell growth by 76.76%. Additionally, it significantly stimulated apoptotic liver cancer cell death with 49.78-fold (22.90% compared to 0.46% for the control) arresting cell cycle Pre-G1 with 35.16% of a cell population, compared to 1.57% for the control. Moreover, it validated the intrinsic apoptosis through upregulation of P53, and other related genes, with inhibition of anti-apoptotic genes through PIM-1 inhibition.

Lichen sclerosus (LS) is a chronic disease of the skin, for which the pathogenesis is not known. It can lead to various changes of the skin and the genital area, potentially leading to both functional as well as cosmetic problems for the patient, thus disrupting the quality of life. In this study; the purpose was to review the clinical characteristics and the treatments of the 15 pediatric patients under the age of 18 followed up in our out-patient clinic with a diagnosis of LS and to compare the findings with literature data. Between 2011 and 2017, the files of 15 patients diagnosed clinically and/or histologically with LS in our clinic were retrospectively examined. The demographic characteristics, clinic and laboratory findings, treatment options of the patients are reported. Of the patients included in the study 14 were girls and one was a boy. The average age was 11.6 years (5-17 years), the average age for the initial disease was 7.8 years (2-13 years). The average duration of the disease at the dxtragenital involvement was the most common on the trunk. Diagnosis, treatment and follow-up during childhood is highly important to prevent any possible future anatomical or psychological damage and genital malignancies. We aimed to investigate the relationship between human leukocyte antigens (HLA)-groups and clinical features, and degree of intestinal injury in children with celiac disease (CD). Study group included 73 (50 females, 68.5%) children with CD. https://www.selleckchem.com/products/FK-506-(Tacrolimus).html Demographic and clinical features, accompanying autoimmune diseases, family history for CD and degree of damage in small intestinal mucosa (according to Marsh classification) at the time of diagnosis were determined. Twenty-two siblings of celiac patients without CD (15 females, 65.2%) consisted control group 1, and 66 (40 females, 60.6%) people from the normal population consisted control group 2. The allele frequencies of HLA B8, B50, C6, C7, DR3, DR7, DQ2, and DR3 homozygosity were higher in the patient group. HLA DQ2 positivity was 89% in the patient group, 73.9 and 45.5% in control groups 1 and 2, respectively (p < 0.0001). HLA A30, C14, DR11, DQ3 frequency were lower in patients compared to both control groups. HLA-DR15 alleles in patient and control group to have a protective role in the same population. Previous studies demonstrated critical deficits in diagnosis and management of childhood food allergy (FA), and recent developments in FA research support adopting a proactive approach in FA management. Our objective was to describe FA knowledge and management patterns of pediatricians. We applied a 24-item survey to 170 general pediatricians, pediatric allergists and pediatric gastroenterologists practicing in Turkey. Some IgE-mediated symptoms of FA such as cough, urticaria, wheezing and anaphylaxis were falsely recognized as symptoms of non-IgE-mediated FA by 30%, 29%, 25% and 19% of the participants, respectively. By contrast, 50% of the participants falsely recognized bloody stool, a finding of IgE-mediated FA. Most frequently and least frequently used diagnostic tools were specific IgE (30.5%) and oral food challenge test (1.7%), respectively. Maternal diet restrictions and infant diet restrictions were advised by 82% and 82%, respectively. Percentages of physicians eliminating only 1 food were 21hasizing the deleterious effects of injudicious and extensive eliminations. Although the exact pathophysiology of functional gastrointestinal diseases remains unclear, numerous etiologies have been blamed, including visceral hypersensitivity, gastrointestinal motility disorders, psychological factors, intestinal mucosal inflammation, intestinal microbiota, and post-infectious syndromes. In the present study, we aimed to evaluate pancreatic insufficient patients diagnosed with functional abdominal pain-not otherwise specified (FAP-NOS) according to Rome IV criteria. The study included a total of 110 patients aged 4-17 years who were diagnosed with FAP-NOS according to Rome IV criteria. The control group consisted of 80 patients with no gastrointestinal disorders and chronic diseases. Glucose, amylase, lipase, pancreatic amylase, immunoreactive trypsinogen (IRT) and fecal elastase (FE-1) levels were examined for each patient. No significant difference was found between the two groups with regard to lipase, pancreatic amylase, IRT, and serum glucose levels. However, the amylase levels were significantly higher and the FE-1 levels were significantly lower in the study group compared to the control group (p=0.007 and p < 0.001). The cut-off value detected in in ROC analysis for the diagnostic value of FE-1 in predicting FAP-NOS was found to be 140.107 μg/g. Based on this value, the sensitivity, specificity, PPV, and NPV of FE-1 were 82.1%, 66.2%, 77%, 73%, respectively. Accordingly, the likelihood of FE-1 in providing a positive value in patients with FAP-NOS was almost 9 times higher than in individuals without FAP-NOS. FE-1 levels were significantly lower in children diagnosed with FAP-NOS and we consider that this difference could be attributed to malabsorption secondary to dysbiosis as there is not enough data. FE-1 levels were significantly lower in children diagnosed with FAP-NOS and we consider that this difference could be attributed to malabsorption secondary to dysbiosis as there is not enough data. Given the high prevalence of potentially traumatic events (PTEs), pediatric providers are in a novel position in early identification and referral of the children with PTEs. Yet paucity of culturally adapted instruments to screen PTEs and related symptoms in preschool-aged children limits pediatric providers. This multicenter study aimed to screen the traumatic life events of preschool-aged children admitted to pediatric outpatient clinics at four different cities of Turkey and to determine the socio-demographic risk factors associated with PTEs. Moreover, it was also intended to develop the cultural adaptation of the Child and Adolescent Trauma Screen (CATS) Caregiver-report 3-6 Years version to Turkish and to analyze its reliability. Participants of this multicenter study were collected from four different hospitals in three different regions (Central Anatolia, Black Sea, and Southeastern Anatolia regions) of Turkey. All parents of children at the age of 3-6 years who were admitted to the hospital for a clinical visit (sick-child or well-child visits) were invited to the study.

Calli derived from young leaves of Aesculus turbinata contained tracheary elements with large pores that resembled perforations of vessel elements. The differentiation of tracheary elements in vitro provides a useful system for detailed analysis of xylem cell differentiation. To examine the mechanism of formation of cell wall structures, new differentiation systems are required that allows us to induce highly organized structures, such as perforations. In this study, we developed such a system in which we were able to induce formation of tracheary elements with perforations, using calli of a hardwood, Aesculus turbinata. Young leaves of A. turbinata were placed on modified MS medium that contained 5μM 2,4-dichlorophenoxyacetic acid (2,4-D) and 5μM benzyladenine (BA). Tracheary elements were induced in calli derived from young leaves of A. turbinata. Some tracheary elements formed broad areas of secondary wall with typical features of secondary xylem. Other tracheary elements formed spiral thickenings, whichturbinata. Newly induced tracheary elements also formed typical features of secondary xylem such as perforations of the vessel elements. Our model system might be useful in efforts to understand the mechanisms of formation of highly organized structures in tracheary elements in secondary xylem.Infection with distinct Zika virus (ZIKV) strains in in vitro and in vivo models has demonstrated that the host's response to infection is strain-dependent. There has been no analysis of the impact of infection with different ZIKV strains on miRNA expression in human cells. We investigated miRNA expression in PNT1A cells upon infection with an African ZIKV strain (MR766) and a Brazilian ZIKV strain (ZIKVBR) using PCR array. Sixteen miRNAs were modulated in PNT1A cells six miRNAs were modulated by both strains, while a set of ten miRNAs were modulated exclusively by ZIKVBR infection. In silico analysis showed that nine significant KEGG pathways and eight significant GO terms were predicted to be enriched upon ZIKVBR infection, and these pathways were related to cancer, environmental information processing, metabolism, and extracellular matrix. Differential modulation of miRNA expression suggests that distinct strains of ZIKV can differentially modulate the host response through the action of miRNAs. The interpretability of convolutional neural networks (CNNs) for classifying subsolid nodules (SSNs) is insufficient for clinicians. Our purpose was to develop CNN models to classify SSNs on CT images and to investigate image features associated with the CNN classification. CT images containing SSNs with a diameter of ≤ 3 cm were retrospectively collected. We trained and validated CNNs by a 5-fold cross-validation method for classifying SSNs into three categories (benign and preinvasive lesions [PL], minimally invasive adenocarcinoma [MIA], and invasive adenocarcinoma [IA]) that were histologically confirmed or followed up for 6.4 years. The mechanism of CNNs on human-recognizable CT image features was investigated and visualized by gradient-weighted class activation map (Grad-CAM), separated activation channels and areas, and DeepDream algorithm. The accuracy was 93% for classifying 586 SSNs from 569 patients into three categories (346 benign and PL, 144 MIA, and 96 IA in 5-fold cross-validation). The nal classification, and the visualization of the separated activated areas was consistent with radiologists' expertise for diagnosing subsolid nodules. • DeepDream showed the image features that CNN learned from a training dataset in a human-recognizable pattern. • CNN achieved high accuracy (93%) in classifying subsolid nodules on CT images into three categories benign and preinvasive lesions, MIA, and IA. • The gradient-weighted class activation map (Grad-CAM) located the entire region of image features that determined the final classification, and the visualization of the separated activated areas was consistent with radiologists' expertise for diagnosing subsolid nodules. • DeepDream showed the image features that CNN learned from a training dataset in a human-recognizable pattern. To investigate the correlation between enhancement degrees of brain metastases on contrast-enhanced T2-fluid-attenuated inversion recovery (CE-T2 FLAIR) and vascular permeability parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Thirty-nine patients with brain metastases were prospectively collected. They underwent non-enhanced T2 FLAIR, DCE-MRI, CE-T2 FLAIR, and contrast-enhanced three-dimensional brain volume imaging (CE-BRAVO). Quantitative parameters of DCE-MRI were evaluated for all lesions, which included volume transfer constant (K ), rate constant (K ), and fractional volume of the extracellular extravascular space (V ). https://www.selleckchem.com/products/acetylcysteine.html Contrast ratio (CR) and percentage increase (PI) values of all lesions on CE-T2 FLAIR were also measured. The tumor enhancement degree on CE-T2 FLAIR in relation to CE-BRAVO was visually classified as higher (group A), equal (group B), and lower (group C). A total of 82 brain metastases were evaluated, including 31 in group A, 19 in group B, and 32R was negatively correlated with Ktrans and Kep values. • The vascular permeability of brain metastasis accounted for the difference in enhancement degree between CE-T2 FLAIR and CE-BRAVO. • CE-T2 FLAIR is useful for detecting brain metastases with mild disruption of the blood-brain barrier. A variety of imaging techniques can be used to evaluate diffusion characteristics to differentiate malignant and benign pancreatic lesions. The diagnostic performance of diffusion parameters has not been systematic assessed. We aimed to investigate the diagnostic efficacy of quantitative diffusion-weighted imaging (DWI) for pancreatic lesions. A literature search was conducted using the PubMed, Embase, and Cochrane Library databases for studies from inception to March 30, 2020, which involves the quantitative diagnostic performance of diffusion-weighted imaging (DWI) and intravoxel incoherent motion (IVIM) in the pancreas. Studies were reviewed according to inclusion and exclusion criteria. The quality of articles was evaluated by the Quality Assessment of Diagnostic Accuracy Studies-2 (QUATAS-2). A bivariate random-effects model was used to evaluate pooled sensitivities and specificities. Univariable meta-regression analysis was used to test the effects of factors that contributed to the heterogeneity.

The present study focused on burning as one of the main causes of mortality with detrimental economic and social effects in the world. The purpose of this study was to investigate the impact of collagen-chitosan gel extracted from and shrimp skin in the treatment of second degree burn healing among rats. To fulfill the purpose of the study, chitosan and collagen were extracted respectively from shrimp and skin waste by the acid-based method and were evaluated by using Pico Tag, SDS-PAGE. The burn wound healing efficiency of marine collagen-chitosan gel was examined invivo using rats. Three different ratios of collagen and chitosan blend (Col-CH, 13, 11 and 31) were prepared to obtain the most effective Col-CH gel for burn wound healing and were compared to the animals treated with silver sulfadiazine ointment. Healing burn wound was studied by measuring wound surface area with Image J and histopathologic examination was carried out based on the mean of epithelialization, fibroblastic cells, acute an was composed of two α (α1 and α2) chains. Amino acid analysis showed a much higher glaycin content in extracted collagen which amounted to one-third of the total amino. The wound surface measurement showed a significant reduction in wound size in the group treated with Col-CH (31) compared to silver-sulfadiazine treated group on 15th and 25th days. Histopathological findings represented a high score in epithelialization, collagen, collagen structure, fibroblast cell and a decrease in inflammatory cells infiltration in Col-CH (31) treated group on 25th day. The most obvious finding of the present study is that chitosan-collagen gel (31) represented a better efficacy compared to sulfadiazine in burn wound healing on day 25 post-burn. The formation of a secondary liver is expected in ectopic transplants in liver therapy. It is reported that the transplantation of hepatocyte sheets constitutes one of the techniques used to form a secondary liver. Accordingly, we established a subcutaneous transplant for hepatocyte/fibroblast sheets in previous studies. In this development study with hepatocyte/fibroblast sheets, we evaluated the differences in transplantation sites to promote the maturation of transplanted tissue in a liver injury model. A cocultured hepatocyte sheet of fibroblasts (TIG-118 cells) and human hepatocytes (PXB cells) was prepared on a temperature-responsive culture dish. The prepared cocultured hepatocyte sheet was either transplanted subcutaneously or on the liver surface of a persistent liver injury model (cDNA-uPA/SCID mouse uPA mouse), and was evaluated by the human albumin concentration in mouse blood. https://www.selleckchem.com/products/at13387.html As a control group, hepatocyte cell sheets were used that were transplanted to both areas and compared. Although the cocultured hepatocyte sheet led to functional improvements in the early stages of culture in subcutaneous transplantation, these did not last in the long-term after transplantation. Although coculture effects were not observed in the liver surface transplantation case, long-term functional expressions in mono- and cocultured sheets in the case of liver surface transplantation were exhibited compared with subcutaneous administration. These results suggest that sustained stimulation of liver regenerationvaries depending on the transplant site and is largely involved in the maturation of hepatocyte tissue. These results suggest that sustained stimulation of liver regenerationvaries depending on the transplant site and is largely involved in the maturation of hepatocyte tissue.The cancer stem cell (CSC) hypothesis was proposed over 4 decades ago and states that tumor growth is maintained by a small subset of cancer cells analogous to normal tissue stem cells in terms of self-renewal and differentiation capacity. Advances in CSC isolation were initially achieved in hematological malignancies and later in solid tumors, including hepatocellular carcinoma (HCC), the major histological type of liver cancer. Increasing evidence suggests the importance of liver CSCs for tumor growth, metastasis, and chemo/radiation resistance in HCC, but the application of the liver CSC concept for the clinical diagnosis and treatment of HCC has not yet been achieved to the extent initially expected. Furthermore, the heterogeneity and plasticity of liver CSCs has recently been noted and might be related to drug resistance and the rapid growth and/or metastasis of the tumor after treatment. Here, we introduce our recent advancement in liver CSC research and discuss the clinical implications, which may lead to the development of improved diagnostics and treatment in HCC.Resilience and well-being are strongly related. People with higher levels of well-being are more resilient after stressful life events or trauma and vice versa. Less is known about the underlying sources of overlap and causality between the constructs. In a sample of 11.304 twins and 2.572 siblings from the Netherlands Twin Register, we investigated the overlap and possible direction of causation between resilience (i.e. the absence of psychiatric symptoms despite negative life events) and well-being (i.e. satisfaction with life) using polygenic score (PGS) prediction, twin-sibling modelling, and the Mendelian Randomization Direction of Causality (MR-DoC) model. Longitudinal twin-sibling models showed significant phenotypic correlations between resilience and well-being (.41/.51 at time 1 and 2). Well-being PGS were predictive for both well-being and resilience, indicating that genetic factors influencing well-being also predict resilience. Twin-sibling modeling confirmed this genetic correlation (0.71) and sulnerability, as resilience and well-being are both negatively related to psychopathology. Bariatric surgery is an effective treatment for severe obesity but causes substantial bone loss and increased risk of fractures. To date, there have been no studies examining whether pharmacologic treatments can prevent bone loss after bariatric surgery. We performed an exploratory study to examine the preliminary safety and efficacy of zoledronic acid (ZOL), a potent anti-resorptive bisphosphonate, to suppress bone turnover markers (BTM) and prevent declines in bone mineral density (BMD) after Roux-en-Y gastric bypass (RYGB) surgery. We performed an open-label pilot study of pre-operative ZOL in postmenopausal women with obesity who were planning RYGB ( =4). A single dose of zoledronic acid 5mg was given intravenously prior to RYGB. Serum bone biochemistries including C-telopeptide (CTX) and procollagen type 1 N-terminal propeptide (P1NP) were measured at multiple timepoints throughout the 24-week study. BMD was also obtained at the spine and hip by dual-energy x-ray absorptiometry (DXA) and at the trabecular spine by quantitative computed tomography (QCT) at pre-operative baseline and 24weeks.
