Greater PTSS symptoms were related to internalizing, externalizing, rumination, and avoidant coping strategies. Coping measurement was constrained due to measurement variance, lack of developmentally and contextually vali-dated instruments, theoretical misalignment, and absence of comprehensive tools to assess coping. Robust and consistent measures of coping should be established to inform research and interventions to reduce the impact of disasters on children's and adolescents' well-being.The antidiabetic drug gliclazide is partly metabolized by CYP2C19, the main enzyme involved in omeprazole metabolism. The aim of the study was to explore the interaction between omeprazole and gliclazide in relation to CYP2C19 phenotype using physiologically based pharmacokinetic (PBPK) modeling approach. Developed PBPK models were verified using in vivo pharmacokinetic profiles obtained from a clinical trial on omeprazole-gliclazide interaction in healthy volunteers, CYP2C19 normal/rapid/ultrarapid metabolizers (NM/RM/UM). In addition, the association of omeprazole cotreatment with gliclazide-induced hypoglycemia was explored in 267 patients with type 2 diabetes (T2D) from the GoDARTS cohort, Scotland. The PBPK simulations predicted 1.4-1.6-fold higher gliclazide area under the curve (AUC) after 5-day treatment with 20 mg omeprazole in all CYP2C19 phenotype groups except in poor metabolizers. The predicted gliclazide AUC increased 2.1 and 2.5-fold in intermediate metabolizers, and 2.6- and 3.8-fold in NM/RM/UM group, after simulated 20-day dosing with 40 mg omeprazole once and twice daily, respectively. The predicted results were corroborated by findings in patients with T2D which demonstrated 3.3-fold higher odds of severe gliclazide-induced hypoglycemia in NM/RM/UM patients concomitantly treated with omeprazole. Our results indicate that omeprazole may increase exposure to gliclazide and thus increase the risk of gliclazide-associated hypoglycemia in the majority of patients.A biomimetic study on the auditory localization mechanism of Ormia ochracea was performed to improve the localization ability of small acoustic systems. We also present a microscale implementation of an acoustic localization device inspired by the auditory organ of the parasitic O. ochracea. The device consists of a pair of circular membranes coupled together with an elastic beam. The coupling serves to amplify the difference in magnitude and phase between the two membranes' responses as the incident angle of the sound changes, allowing directional information to be deduced from the coupled device response. The research results show that the intermembrane bridge structure improves the sound source localization and directional weak acoustic signal acquisition of sound detectors. The recognition rate of the phase difference and amplitude ratio was greatly improved. The theoretical resolution of the incident angle of the sound source can reach 2° at a phase difference recognition rate of 5°. The sound source's optimal identification frequency range for the coupling device based on the intermembrane bridge bionic structure is 300 Hz to 1500 Hz.Hepatitis A (HA) is an acute human infectious disease caused by a positive single-stranded RNA virus (HAV). It is mainly acquired through the fecal-oral route and is primarily spread by contact between people and exposure to contaminated water and food. Recently, large outbreaks of HA have been reported by low and moderate endemicity countries, emphasizing its importance in public health and the need for rapid and large-scale diagnostic tests to support public health decisions on HA. This work proposes a new tool for HAV diagnosis based on the association of surface plasmonic resonance with major capsid protein VP1 (SPR-HAVP1 assay), detecting IgM antibodies for HAV in human serum samples. Structural analyses of VP1 B-lymphocyte epitopes showed continuous and discontinuous epitopes. The discontinuous epitopes were identified in the N-terminal region of the VP1 protein. Both epitope types in the VP1 protein were shown by the reactivity of VP1 in native and denaturing conditions to IgM anti-HAV, which was favorable to tests of VP1 in the SPR assays. SPR-HAVP1 assays showed good performance in the detection of IgM polyclonal antibody anti-HAV. These assays were performed using a COOH5 sensor chip functionalized with VP1 protein. The sensorgram record showed a significant difference between positive and negative serum samples, which was confirmed by analysis of variation of initial and final dissociation values through time (ΔRUd/t). The data gathered here are unequivocal evidence that the SPR-HAVP1 strategy can be applied to detect IgM antibodies in human serum positive to the HAV. This is a new tool to be explored to diagnose human HAV infections.In this paper, we report a scheme providing precise spectral analysis and surface imaging, simultaneously, based on a high-coherence dual-comb interferometer. With two tightly phase-locking frequency combs, we demonstrate a high-coherence dual-comb interferometer (DCI) covering 188 to 195 THz (1538.5 to 1595.7 nm) with comb-tooth resolution and a max spectral signal-to-noise ratio (SNR) of 159.7. The combination of the high-coherence dual-comb spectrometer and a reference arm simultaneously enables gas absorption spectroscopy and for the absolute distance information to be obtained in one measurement. As a demonstration, we measure the spectrum of CO2 and CO. From the same interferograms, we demonstrate that distance measurement, by time-of-flight (TOF), can be resolved with an rms precision of 0.53 μm after averaging 140 images and a measurement time of 1 s. Finally, we demonstrate that non-contact surface imaging, using 2D mechanical scanning, reaches lateral resolution of 40 μm. The longitudinal precision is 0.68 μm with a measurement time of 0.5 s. It verifies that DCS has the potential to be applied in standoff detection, environmental pollution monitors, and remote sensing.Among vaccines administered to children are those targeting rotavirus, a segmented double-stranded RNA virus that represents a major cause of severe gastroenteritis. To explore the feasibility of establishing a combined rotavirus-SARS-CoV-2 vaccine, we generated recombinant (r)SA11 rotaviruses with modified segment 7 RNAs that contained coding cassettes for NSP3, a translational 2A stop-restart signal, and a FLAG-tagged portion of the SARS-CoV-2 spike (S) protein S1 fragment, N-terminal domain (NTD), receptor-binding domain (RBD), extended RBD (ExRBD), or S2 core (CR) domain. Generation of rSA11 containing the S1 coding sequence required a sequence insertion of 2.2 kbp, the largest such insertion yet introduced into the rotavirus genome. Immunoblotting showed that rSA11 viruses containing the smaller NTD, RBD, ExRBD, and CR coding sequences expressed S-protein products of expected size, with ExRBD expressed at highest levels. https://www.selleckchem.com/GSK-3.html These rSA11 viruses were genetically stable during serial passage. In contrast, the rSA11 virus containing the full-length S coding sequence (rSA11/NSP3-fS1) failed to express its expected 80 kDa fS1 product, for unexplained reasons.

Objectives Sapovirus is increasingly recognized as an important cause of acute gastroenteritis (AGE) worldwide, however studies of prevalence, genetic diversity and strain-specific clinical implications have been scarce. Methods To fill this knowledge gap, we used reverse transcription real-time PCR and sequencing of the partial major capsid protein VP1 gene to analyze stool specimens and rectal swabs obtained from 3347 children with AGE and 1355 asymptomatic controls (all less then 18 years old) collected between December 2014 and August 2018 in Alberta, Canada. Results Sapovirus was identified in 9.5% (317/3347) of the children with AGE and 2.9% of controls. GI.1 (36%) was the predominant genotype identified, followed by GI.2 (18%), GII.5 (8%) and GII.3 (6%). Rare genotypes GII.1, GII.2, GV.1, GII.4, GIV.1, GI.3 and GI.7 were also seen. Sapovirus was detected year-round, peaking during the winter months of November to January. The exception was the 2016-2017 season when GI.2 overtook GI.1 as the predominant strain with a high detection rate persisting into April. We did not observe significant difference in the severity of gastroenteritis by genogroup or genotype. Repeated infection by sapovirus of different genogroups occurred in three controls who developed AGE later. Conclusions Our data suggests that sapovirus is a common cause of AGE in children with high genetic diversity.Determinants of protective immunity against SARS-CoV-2 infection require the development of well-standardized, reproducible antibody assays. This need has led to the emergence of a variety of neutralization assays. Head-to-head evaluation of different SARS-CoV-2 neutralization platforms could facilitate comparisons across studies and laboratories. Five neutralization assays were compared using forty plasma samples from convalescent individuals with mild-to-moderate COVID-19 four cell-based systems using either live recombinant SARS-CoV-2 or pseudotyped viral particles created with lentivirus (LV) or vesicular stomatitis virus (VSV) packaging and one surrogate ELISA-based test that measures inhibition of the spike protein receptor binding domain (RBD) binding its receptor, human angiotensin converting enzyme 2 (hACE2). Vero, Vero E6, HEK293T expressing hACE2, and TZM-bl cells expressing hACE2 and transmembrane serine protease 2 were tested. All cell-based assays showed 50% neutralizing dilution (ND50) geometric mean titers (GMTs) that were highly correlated (Pearson r = 0.81-0.89) and ranged within 3.4-fold. The live-virus assay and LV-pseudovirus assays with HEK293T/hACE2 cells showed very similar mean titers 141 and 178, respectively. ND50 titers positively correlated with plasma IgG targeting SARS-CoV-2 spike and RBD (r = 0.63-0.89), but moderately correlated with nucleoprotein IgG (r = 0.46-0.73). https://www.selleckchem.com/mTOR.html ND80 GMTs mirrored ND50 data and showed similar correlation between assays and with IgG concentrations. The VSV-pseudovirus assay and LV-pseudovirus assay with HEK293T/hACE2 cells in low and high-throughput versions were calibrated against the WHO SARS-CoV-2 IgG standard. High concordance between the outcomes of cell-based assays with live and pseudotyped virions enables valid cross-study comparison using these platforms. 249.The use of human tissue stem cell-derived organoids has advanced our knowledge of human physiologic and pathophysiological processes that are unable to be studied using other model systems. Increases in the understanding of human epithelial tissues including intestine, stomach, liver, pancreas, lung, and brain have been achieved using organoids. However, it is not yet clear whether these cultures recapitulate in vivo organ-to-organ signaling or communication. In this work, we demonstrate that mature stem cell-derived intestinal and liver organoid cultures each express functional molecules that modulate bile acid uptake and recycling. These organoid cultures can be physically coupled in a Transwell® system and display increased secretion of FGF19 (intestine) and downregulation of CYP7A (liver) in response to apical exposure of the intestine to bile acids. This work establishes that organoid cultures can be used to study and therapeutically modulate interorgan interactions and advance the development of personalized approaches to medical care.Extracellular vesicles (EVs) contain biological molecules and are secreted by cells into the extracellular milieu. The endothelial sodium channel (EnNaC) plays an important role in modulating endothelial cell stiffness. We hypothesized EVs secreted from human aortic endothelial cells (hAoEC) positively regulate EnNaC in an autocrine dependent manner. A comprehensive lipidomic analysis using targeted mass spectrometry was performed on multiple preparations of EVs isolated from the conditioned media of hAoEC or complete growth media of these cells. Cultured hAoEC challenged with EVs isolated from the conditioned media of these cells resulted in an increase in EnNaC activity when compared to the same concentration of media derived EVs or vehicle alone. EVs isolated from the conditioned media of hAoEC but not human fibroblast cells were enriched in MARCKS Like Protein 1 (MLP1). The pharmacological inhibition of the negative regulator of MLP1, protein kinase C, in cultured hAoEC resulted in an increase in EV size and release compared to vehicle or pharmacological inhibition of protein kinase D. The MLP1 enriched EVs increased the density of actin filaments in cultured hAoEC compared to EVs isolated from human fibroblast cells lacking MLP1. We quantified 141 lipids from glycerolipids, glycerophospholipids, and sphingolipids in conditioned media EVs that represented twice the number found in control media EVs. The concentrations of sphingomyelin, lysophosphatidylcholine and phosphatidylethanolamine were higher in conditioned media EVs. These results provide the first evidence for EnNaC regulation in hAoEC by EVs and provide insight into a possible mechanism involving MLP1, unsaturated lipids, and bioactive lipids.The peroxisome proliferator activated receptors (PPARs) are a group of transcription factors belonging to the nuclear receptor superfamily. Since most target genes of either PPARs are implicated in lipid and glucose metabolism, regulation by PPARs could be used as a screening tool to identify novel genes involved in lipid or glucose metabolism. Here, we identify Adtrp, a serine hydrolase enzyme that was reported to catalyze the hydrolysis of fatty acid esters of hydroxy fatty acids (FAHFAs), as a novel PPAR-regulated gene. Adtrp was significantly upregulated by PPARα activation in mouse primary hepatocytes, liver slices, and whole liver. In addition, Adtrp was upregulated by PPARγ activation in 3L3-L1 adipocytes and in white adipose tissue. ChIP-SEQ identified a strong PPAR binding site in the immediate upstream promoter of the Adtrp gene. Adenoviral-mediated hepatic overexpression of Adtrp in diet-induced obese mice caused a modest increase in plasma non-esterified fatty acids but did not influence diet-induced obesity, liver triglyceride levels, liver lipidomic profiles, liver transcriptomic profiles, and plasma cholesterol, triglycerides, glycerol, and glucose levels.

Lateral extra-articular tenodesis (LET) is one of the most widely used procedures to restore anterolateral stability. Clinical outcomes after the addition of LET to anterior cruciate ligament (ACL) reconstruction (ACLR) have been widely investigated; however, the potential influence of LET on the ACL ligamentization process has not been examined. The purpose was to use 10-month postoperative magnetic resonance imaging (MRI) scans to determine whether the maturity of grafts after hamstring autograft ACLR was affected by concomitant LET. The hypothesis was that when modified Lemaire lateral extra-articular tenodesis (MLLET) was performed, the MRI parameters of ACL graft maturity would be modified. Cohort study; Level of evidence, 3. The study included patients treated between December 2017 and December 2018 who had undergone anatomic 3-strand hamstring tendon autograft ACLR, with or without concomitant MLLET, and had undergone MRI 10 months postoperatively. Thus, the study included 30 patients who had its for anatomic ACLR with MLLET did not show the same MRI signal intensity compared with isolated hamstring anatomic ACLR.When performing a physically demanding behavior, sometimes the optimal choice is to quit the behavior rather than persist to minimize energy expenditure for the benefits gained. The dorsomedial prefrontal cortex (dmPFC), consisting of the anterior cingulate cortex and secondary motor area, likely contributes toward such utility assessments. Here, we examined how male rat dmPFC single unit and ensemble-level activity corresponded to changes in task utility and quitting in an effortful weight lifting task. Rats carried out two task paradigms one that became progressively more physically demanding over time and a second fixed effort version. Rats could quit the task at any time. Dorsomedial PFC neurons were highly responsive to each behavioral stage of the task, consisting of rope pulling, reward retrieval, and reward area leaving. Activity was highest early in sessions, commensurate with the highest relative task utility, then decreased until the point of quitting. https://www.selleckchem.com/products/pf-05251749.html Neural ensembles consistently represented the sequential behavioral phases of the task. However, these representations were modified over time and became more distinct over the course of the session. These results suggest that dmPFC neurons represent behavioral states that are dynamically modified as behaviors lose their utility, culminating in task quitting.NEW & NOTEWORTHY When carrying out a physically demanding task, animals must continually assess whether to persist or quit. In this study, we recorded neurons in the dorsomedial prefrontal cortex (dmPFC) of rats as they carried out a challenging weightlifting task, up to the point of quitting. We demonstrate that dmPFC neurons form a representation of the task that is modified, via a decrease in firing rate, by the decreasing the utility of the task that may signal quitting.Faces are stimuli of critical importance for primates. The common marmoset (Callithrix jacchus) is a promising model for investigations of face processing, as this species possesses oculomotor and face-processing networks resembling those of macaques and humans. Face processing is often disrupted in neuropsychiatric conditions such as schizophrenia (SZ), and thus, it is important to recapitulate underlying circuitry dysfunction preclinically. The N-methyl-d-aspartate (NMDA) noncompetitive antagonist ketamine has been used extensively to model the cognitive symptoms of SZ. Here, we investigated the effects of a subanesthetic dose of ketamine on oculomotor behavior in marmosets during face viewing. Four marmosets received systemic ketamine or saline injections while viewing phase-scrambled or intact videos of conspecifics' faces. To evaluate effects of ketamine on scan paths during face viewing, we identified regions of interest in each face video and classified locations of saccade onsets and landing positions marmosets to model the cognitive symptoms of schizophrenia. We observed a disruption of scan paths during viewing of conspecifics' faces. These findings support the use of ketamine in marmosets as a model for investigating social cognition in neuropsychiatric disorders.Implementation research ethics can be particularly challenging when pregnant women have been excluded from earlier clinical stages of research given greater uncertainty about safety and efficacy in pregnancy. The evaluation of human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) during pregnancy offered an opportunity to understand important ethical considerations and social influences shaping women's decisions to participate in the evaluation of PrEP and investigational drugs during pregnancy. We conducted interviews with women (n = 51), focus groups with male partners (five focus group discussions [FGDs]), interviews with health providers (n = 45), four FGDs with pregnant/postpartum adolescents and four FGDs with young women. Data were analyzed using thematic content analysis, including ethical aspects of the data. Our study reveals that women navigate a complex network of social influences, expectations, support, and gender roles, not only with male partners, but also with clinicians, family, and friends when making decisions about PrEP or other drugs that lack complete safety data during pregnancy.The use of transcranial magnetic stimulation to assess the excitability of the central nervous system to further understand the neural control of human movement is expansive. The majority of the work performed to-date has assessed corticospinal excitability either at rest or during relatively simple isometric contractions. The results from this work are not easily extrapolated to rhythmic, dynamic motor outputs, given that corticospinal excitability is task-, phase-, intensity-, direction-, and muscle-dependent (Power KE, Lockyer EJ, Forman DA, Button DC. Appl Physiol Nutr Metab 43 1176-1185, 2018). Assessing corticospinal excitability during rhythmic motor output, however, involves technical challenges that are to be overcome, or at the minimum considered, when attempting to design experiments and interpret the physiological relevance of the results. The purpose of this narrative review is to highlight the research examining corticospinal excitability during a rhythmic motor output and, importantly, to provide recommendations regarding the many factors that must be considered when designing and interpreting findings from studies that involve limb movement.

While surgery remains the mainstay of therapy, novel medical and radiopharmaceutical approaches are available for patients with progressive and/or unresectable tumors.Septo-optic dysplasia (SOD) or de Morsier's syndrome is a rare congenital disorder characterized by a classic triad of (a) optic nerve hypoplasia, (b) agenesis of septum pellucidum and corpus callosum, and (c) hypoplasia of the hypothalamic-pituitary axis. This chapter will outline the key information regarding the etiology and epidemiology of this syndrome with a focus on its comprehensive management. Particular attention will be paid to the diagnostic stage and the most relevant differential diagnosis, before moving to the complexities of its treatment. In fact, although SOD is not curable, many aspects of this syndrome can be improved through a tailored multidisciplinary approach consisting in hormonal replacement, corrective ophthalmological surgery, management of epileptic seizures, and active neuropsychological support.Puberty, which in humans is considered to include both gonadarche and adrenarche, is the period of becoming capable of reproducing sexually and is recognized by maturation of the gonads and development of secondary sex characteristics. Gonadarche referring to growth and maturation of the gonads is fundamental to puberty since it encompasses increased gonadal steroid secretion and initiation of gametogenesis resulting from enhanced pituitary gonadotropin secretion, triggered in turn by robust pulsatile GnRH release from the hypothalamus. This chapter reviews the development of GnRH pulsatility from before birth until the onset of puberty. In humans, GnRH pulse generation is restrained during childhood and juvenile development. This prepubertal hiatus in hypothalamic activity is considered to result from a neurobiological brake imposed upon the GnRH pulse generator resident in the infundibular nucleus. Reactivation of the GnRH pulse generator initiates pubertal development. Current understanding of the genetics and physiology of the brake will be discussed, as will hypotheses proposed to account for timing the resurgence in pulsatile GnRH and initiation of puberty. The chapter ends with a discussion of disorders associated with precocious or delayed puberty with a focus on those with etiologies attributed to aberrant GnRH neuron anatomy or function. A pediatric approach to patients with pubertal disorders is provided and contemporary treatments for both precocious and delayed puberty outlined.Klinefelter syndrome (47,XXY) is a frequent chromosomal disorder among males, often presenting with hypergonadotropic hypogonadism, small firm testicles, metabolic disorders, neurocognitive challenges, and increased height. Neurologic disorders such as epilepsy, seizures, and tremor as well as psychiatric disorders are also seen more frequently. The neurocognitive deficits seen are present in many areas of cognition, typically affecting general cognitive abilities, language, and executive functioning. Also, social dysfunction is frequent. Dyslexia is present in more than half of all males. Brain imaging studies generally show a typical pattern, with many nuclei and brain areas being smaller than among controls. However, it has not been possible to link the brain alterations found in imaging studies with the neurocognitive profile. The genetics underlying the phenotypic traits found among males with Klinefelter syndrome still remains to be elucidated; however, recent studies have described pervasive changes in the methylome and transcriptome and new and interesting candidate genes have been pinpointed, but their involvement in the phenotype of Klinefelter syndrome has not been proven.Gender identity (an individual's perception of being male or female) and sexual orientation (heterosexuality, homosexuality, or bisexuality) are programmed into our brain during early development. https://www.selleckchem.com/products/crenolanib-cp-868596.html During the intrauterine period in the second half of pregnancy, a testosterone surge masculinizes the fetal male brain. If such a testosterone surge does not occur, this will result in a feminine brain. As sexual differentiation of the brain takes place at a much later stage in development than sexual differentiation of the genitals, these two processes can be influenced independently of each other and can result in gender dysphoria. Nature produces a great variability for all aspects of sexual differentiation of the brain. Mechanisms involved in sexual differentiation of the brain include hormones, genetics, epigenetics, endocrine disruptors, immune response, and self-organization. Furthermore, structural and functional differences in the hypothalamus relating to gender dysphoria and sexual orientation are described in this review. All the genetic, postmortem, and in vivo scanning observations support the neurobiological theory about the origin of gender dysphoria, i.e., it is the sizes of brain structures, the neuron numbers, the molecular composition, functions, and connectivity of brain structures that determine our gender identity or sexual orientation. There is no evidence that one's postnatal social environment plays a crucial role in the development of gender identity or sexual orientation.Aneurysmal subarachnoid hemorrhage (aSAH) results from the rupture of an intracranial aneurysm and represents a highly debilitating and devastating disorder. The prevalence rate of neuroendocrine impairment in the acute phase is extremely variable, ranging from 3.8% to 92.3%, depending on the time point considered, the method/test utilized, the clinical severity at admission, and probably also ethnicity. Further studies are needed to clarify such a wide range in neuroendocrine dysfunction in patients with aSAH. The overall neuroendocrine impairment rate in chronic aSAH is in the range 47%-83.3% with specific neuroendocrine impairment varying from 2.5% to 83.3%. The overall pituitary deficiency rate tends to decrease over time after SAH, with recovery of most endocrine and some de novo dysfunctions being reported. Only one study has reported an increase of overall endocrine impairment in the chronic follow-up. Neuroendocrine dysfunction seems to have a high prevalence in aSAH patients, even though its exact impact is not precisely known and is based on contrasting findings.

Women who faced longer periods of incarceration following birth and separation from their newborns reported higher levels of postpartum depressive symptoms. Findings have implications for practice and policy aimed at supporting the mental health needs of women who are pregnant in prison, particularly those women who give birth in custody and are separated from their newborns. Findings have implications for practice and policy aimed at supporting the mental health needs of women who are pregnant in prison, particularly those women who give birth in custody and are separated from their newborns. Pregnancy creates a unique window of opportunity for smoking cessation. However, pregnant women from underserved groups can face personal, social, and environmental challenges that impede quitting. This study draws upon the socioecological framework to explore perspectives on smoking cessation among pregnant and postpartum women from low-income groups in the mid-South of the United States. Semistructured interviews were conducted with 60 women who were pregnant or postpartum. Data were analyzed in Dedoose qualitative software using the directed content analysis approach. Findings reveal that at the individual level, motivations for smoking cessation included the fact of being pregnant, risks associated with the infant's health, and desire to breastfeed. However, some pregnant women perceived that slowing down on smoking during pregnancy was adequate to prevent harm to their fetuses. Individual-level factors that made smoking cessation difficult included nicotine addiction and habit, boredom, stressful lcessation outcomes. This study offers theoretical insights into factors that function as barriers or facilitators of smoking cessation among pregnant and postpartum women from low-income groups in the United States. Designing multilevel smoking cessation interventions while considering the interplay of individual, interpersonal, organizational, and policy level factors may lead to better cessation outcomes.Plants have adapted to different environmental niches by fine-tuning the developmental factors working together to regulate traits. Variations in the developmental factors result in a wide range of quantitative variations in these traits that helped plants survive better. The major developmental pathways affecting plant architecture are also under the control of such pathways. Most notable are the CLAVATA-WUSCHEL pathway regulating shoot apical meristem fate, GID1-DELLA module influencing plant height and tillering, LAZY1-TAC1 module controlling branch/tiller angle, and the TFL1-FT determining the floral fate in plants. Allelic variants of these key regulators selected during domestication shaped the crops the way we know them today. https://www.selleckchem.com/products/U0126.html There is immense yield potential in the "ideal plant architecture" of a crop. With the available genome editing techniques, possibilities are not restricted to naturally occurring variations. Using a transient reprogramming system, one can screen the effect of several developmental gene expressions in novel ecosystems to identify the best targets. We can use the plant's fine-tuning mechanism for customizing crops to specific environments. The process of crop domestication can be accelerated with a proper understanding of these developmental pathways. It is time to step forward towards the next-generation molecular breeding for restructuring plant types in crops ensuring yield stability. Charge density mapping of atrial fibrillation (AF) reveals dynamic localized rotational activation (LRA), irregular activation (LIA) and focal firing (FF). Their spatial stability, conduction characteristics and the optimal duration of mapping required to reveal these phenomena and has not been explored. Bi-atrial mapping of AF propagation was undertaken using AcQMap (Acutus Medical) and variability of activation patterns quantified up to a duration of 30 s. The frequency of each pattern was quantified at each unique point of the chamber over two separate 30-s recordings before ablation and R calculated to quantify spatial stability. Regions with the highest frequency were identified at increasing time durations and compared to the result over 30 s using Cohen's kappa. Properties of regions with the most stable patterns were assessed during sinus rhythm and extrastimulus pacing. In 21 patients, 62 paired LA and RA maps were obtained. LIA was highly spatially stable with R between maps of 0.83 (0.71-ulus pacing and may represent fixed anatomical substrate. The possible association between psoriatic/psoriatic arthritis (PsA) and bone loss has been observed; however, studies have yielded inconclusive results. This meta-analysis aimed to assess whether there is an increase in the risk of osteoporosis, osteopenia and fractures in patients with psoriasis/PsA, compared with healthy individuals. PubMed and Scopus were systematically searched from their inception to September 2020 to identify relevant studies. Relative risk, hazard ratio or odds ratio (OR), with their corresponding 95% confidence intervals (95% CI) were calculated and pooled using arandom-effectsmodel. A total of 12 different studies, with a total of 199389296 participants, were included. Overall, no significant relationship was observed between psoriasis/PsA and the risk of osteoporosis (psoriasis OR = 1.28, 95%CI = 0.86-1.90; PsA OR = 1.32, 95%CI = 0.79-2.19) and osteopenia (psoriasis OR = 1.50, 95%CI = 0.75-3.02; PsA OR = 1.61, 95%CI = 0.67-3.85). However, in the subgroup analysis, psoriasis was significantly associated with an increased risk of osteoporosis in men (OR = 1.27, 95%CI = 1.02-1.59) and studies with cohort design (OR = 1.04, 95%CI = 1.003-1.09). Psoriasis was also related to the risk of osteopenia in studies on a combination of both genders (OR = 2.86, 95%CI = 2.70-3.02). The pooled analysis demonstrated a significantly higher risk of fractures among patients with psoriasis (OR = 1.29, 95%CI = 1.02-1.63) and PsA (OR = 2.88, 95%CI = 1.51-5.48), compared with participants without psoriasis/PsA. Patients with psoriasis/PsA have an increased risk of fractures. There is little evidence supporting the relation of psoriasis to osteoporosis/osteopenia. Patients with psoriasis/PsA have an increased risk of fractures. There is little evidence supporting the relation of psoriasis to osteoporosis/osteopenia.

caused genotoxic stress in tumor-free tissues. HIPEC with cisplatin at ZT0 had a better efficacy/toxicity profile than HIPEC with cisplatin at ZT12 and IV administration at both time points.Primary central nervous system lymphoma (PCNSL) is a rare subtype of extranodal non-Hodgkin lymphoma, and the most frequent histological type is diffuse large B-cell lymphoma (DLBCL). Bruton's tyrosine kinase inhibitor (BTKi) has shown clinical activity in DLBCL. We herein report a 53-year-old man who presented with binocular diplopia, gait instability, dizziness and bucking. He was diagnosed with PCNSL by cranial magnetic resonance imaging (MRI) scan and brain biopsy. Next-generation sequencing (NGS) examination identified multiple genetic abnormalities. The patient was started on a high-dose methotrexate (HD-MTX)-based protocol for two courses. However, the patient developed disease progression. The patient's phenotypic and genetic characteristics strongly suggested BN2-DLBCL, and zanubrutinib was added to the subsequent chemotherapy regimen. The treatment was well tolerated, and complete remission (CR) was achieved after three courses of chemotherapy with the new regimen. The patient then received autologous hematopoietic stem cell transplantation after four courses of chemotherapy with the new regimen. MRI revealed stable CR. Here, we report a successful case of refractory PCNSL treated with zanubrutinib. Small molecules, such as zanubrutinib, may be selectively integrated into first-line regimens of PCNSL to enhance curative effect and reduce recurrence. ALDOA plays an essential role in cancer progression in different human cancers; however, its function has not been understood in prostate cancer (PCa). Associations of ALDOA expression with clinicopathological features and patient prognosis in PCa were evaluated based on data obtained from the Taylor database and our clinical tissue microarray. The potential roles of ALDOA in malignant progression were verified using a series of in vivo and in vitro experiments after stable ALDOA overexpression and knockdown in DU145 and PC3 cell lines. An aldolase A inhibitor was used to determine the effects of inhibition of ALDOA on PCa cell proliferation. Higher expression of ALDOA was positively correlated with the incidence of postoperative metastasis and biochemical recurrence (BCR) and may predict poor prognosis in PCa patients. https://www.selleckchem.com/products/pf-05251749.html In vivo experiments demonstrated that overexpression of ALDOA could significantly promote cell proliferation, prolong the cell cycle, and significantly reduce the apoptosis rate of PCa c-ALDOA signaling axis may be a new target for the clinical treatment of PCa patients given its negative regulatory relationship. Our study suggests that Aldolase A inhibitors may represent a novel approach to inhibit the growth of PCa. The severity of mental health issues among university students in rural areas can affect the outcomes of their studies. The purpose of this study was to identify factors associated with self-esteem, resilience, mental health, and psychological self-care among university students. We conducted a cross-sectional survey of 729 undergraduate students by a self-administered questionnaire. Using convenience sampling, the participants were chosen from four majoring in Public Health at University of Phayao in Northern Thailand. Approximately 82% of university students had mental health problem. Backward logistic regression analysis showed that 1) a good relationship with family had a significantly positive effect on self-esteem (p-value <0.05); 2) a good relationship with friends was significantly associated with high resilience (p-value <0.05); 3) having a disease/s and a relationship with family had a significant effect on mental health problem (p-value <0.05); 4) being female, perceived normal weighe an intervention program and provide services that could mitigate mental health problems and improve the well-being of students at their university. The number of patients attending emergency departments (EDs) fell dramatically in 2020, during the COVID-19 pandemic, compared with similar periods in 2019 or 2018, and healthcare providers have had to adjust to this change. The aim of this study was to compare the number and type of patients attending a hospital emergency unit before and during the COVID-19 pandemic in order to avoid the impact of any difference on the community's healthcare and on healthcare providers. This study assessed differences in the numbers of patients attending the emergency department in 2018, 2019 and 2020, and then determined whether a particular patient type accounted for any such difference. An open-source data repository was accessed to collect the data targeting a private hospital in Riyadh city, the capital of Saudi Arabia. Descriptive statistics and a paired -test were used to verify the level of variations in the number of patients attending the emergency rooms. Results showed no statistically significant difference in the number of patients attending the emergency department between 2018 and 2019, while a noticeable drop was found in the number of patients attending the department between 2019 and 2020. The reduction in the number of patients attending the emergency department was found in some but not all patient types. These conclusion highlight variations in ED attendance of which hospital management should be aware so that action can be taken to avoid negative consequences.

Residential aged care facilities face the immense challenge of adapting to the increasingly high needs of their residents, while delivering personalised, holistic care. There is considerable evidence that music can provide an affordable, accessible way to reduce changes in behaviour associated with dementia, in order to meet these standards of care. However, a number of barriers exist to the effective implementation of music programs in long-term aged care facilities. This study involved focus groups with 17 participants including staff in residential aged care facilities and family caregivers to investigate the benefits of music programs, as well as the challenges and possible solutions to them. A general inductive approach was taken to data analysis. A number of benefits of music programs were identified, including improvements to the wellbeing of both residents of aged care facilities and their caregivers. However, an ingrained culture within residential aged care of focusing on physical care rather than thinking holistically about wellbeing was identified as a significant barrier.

5. Environmental impact assessment indicates that the proposed recycling route allows remarkable reduction of global warming and toxicity impacts compared with metal production from virgin mining and reference processes. We further unveiled the applicability of the electrodeposition technique in the context of anthropogenic mineral recycling, emphasizing resource sustainability and cleaner production.Quaternary nonlinear optical single crystals AgxGaxGe1-xSe2 (x = 0.250, 0.167) were grown by the Bridgman method in a four-zone furnace. The thermal expansion behavior of AgxGaxGe1-xSe2 (x = 0.25, 0.167) was studied by the method of single-crystal X-ray diffraction from 150 to 295 K and powder X-ray diffraction in the range of 298-773 K. Both results show the crystals have positive linear thermal expansion coefficients in different directions and a positive volume thermal expansion coefficient, and it is observed that they satisfy the relationship of αa > αc > αb and αV ≈ αa + αb + αc for the orthorhombic structure. It is found that the AgxGaxGe1-xSe2 (x = 0.25, 0.167) unit cells varying with temperature were mainly dominated by variations in framework geometry (AgSe4 tetrahedron), and the thermal motion of Ag atoms in the AgSe4 tetrahedron. As it was revealed, according to the powder X-ray diffraction, it is found that the isotropic thermal atomic displacement parameter of the Ag atoms is much larger than those of the Se and Ga(Ge) atoms in the AgSe4 tetrahedron. https://www.selleckchem.com/products/delamanid.html Furthermore, anisotropic atomic displacement parameters (ADPs) of Ag atoms are extracted from the single-crystal diffraction; the ADPs along the a axis, b axis, and c axis have a significant difference, which means the thermal vibration of Ag atoms is anisotropic. It is of great significance for improving crystal growth technology and understanding the thermal properties of this kind of crystals.Copper-based sulfides are promising materials for thermoelectric applications, which can convert waste heat into electricity. This study reports the enhanced thermoelectric performance of Cu26V2Ge6S32 colusite via substitution of antimony (Sb) for germanium (Ge) and introduction of copper (Cu) as an interstitial atom. The crystal structure of the solid solutions and Cu-rich compounds were analyzed by powder X-ray diffraction and scanning transmission electron microscopy. Both chemical approaches decrease the hole carrier concentration, which leads to a reduction in the electronic thermal conductivity while keeping the thermoelectric power factor at a high value. Furthermore, the interstitial Cu atoms act as phonon scatterers, thereby decreasing the lattice thermal conductivity. The combined effects increase the dimensionless thermoelectric figure of merit ZT from 0.3 (Cu26V2Ge6S32) to 0.8 (Cu29V2Ge5SbS32) at 673 K.New neutral iridium(III) complexes featuring a cubic polyhedral oligomeric silsesquioxane (POSS) unit, [Ir(N∧C)2(L1-POSS)] [HN∧C = 2-phenylpyridine (Hppy; 1), 2-phenylbenzothioazole (Hbt; 2), and 2-(1-naphthyl)benzothiazole (Hbsn; 3); L1-POSS = (E)-4-[(2-hydroxybenzylidene)amino]benzyl 3-heptakis(isobutyl)POSS-propyl carbamate], were designed and synthesized. Their POSS-free counterparts, [Ir(N∧C)2(L1)] [L1 = (E)-N-(4-hydroxymethylphenyl)-1-(2-hydroxyphenyl)methanimine; HN∧C = Hppy (1a), Hbt (2a), and Hbsn (3a)], and the poly(ethylene glycol) (PEG) derivatives [Ir(N∧C)2(L1-PEG)] [L1-PEG = (E)-4-[(2-hydroxybenzylidene)amino]benzyl 3-[2-[ω-methoxypoly(1-oxapropyl)]ethyl]carbamate; HN∧C = Hppy (1b), Hbt (2b), and Hbsn (3b)] were also prepared. The photophysical, photochemical, and biological properties of the POSS complexes were compared with those of their POSS-free and PEG-modified counterparts. Upon irradiation, all of these complexes displayed orange-to-red emission and long emission lifetimes under ambient hways of these complexes were also investigated. This work not only offers promising luminescent probes for lipid droplets through the structural modification of iridium(III) complexes but also paves the way to the construction of new reagents for theranostics.Minimum and zero liquid discharge (MLD/ZLD) are emerging brine management strategies that attract heightened attention. Although conventional reverse osmosis (RO) can improve the energy efficiency of MLD/ZLD processes, its application is limited by the maximum hydraulic pressure (ΔPmax) that can be applied in current membrane modules. To overcome such limitation, novel RO-based technologies, including osmotically assisted RO (OARO) and low-salt-rejection RO (LSRRO), have been proposed. Herein, we utilize process modeling to systematically compare the energy consumption of OARO and LSRRO for MLD/ZLD applications. Our modeling results show that the specific energy consumption (SEC) of LSRRO is lower (by up to ∼30%) than that of OARO for concentrating moderately saline feed waters (∼70,000 mg/L TDS). However, by implementing more stages and/or an elevated ΔPmax, LSRRO has the potential to outperform OARO energetically for treating high-salinity feed waters. Notably, the SEC of both OARO and LSRRO could be 50% lower than that of mechanical vapor compressor, the commonly used brine concentrator in MLD/ZLD applications. We conclude with a discussion on the practicability of OARO and LSRRO based on membrane module availability and capital cost, suggesting that LSRRO could potentially be more feasible than OARO.It is of great significance to disclose the diverse aging pathways for polymers under multiple factors, so as to predict and control the potential aging evolution. However, the current methods fail to distinguish multiple pathways (multi-paths) of polymer aging due to the lack of spatiotemporal resolution. In this work, using polyimide as a model polymer, the hydroxyl, carboxyl, and amino groups from the polyimide aging process were labeled using specific fluorescent probes through boron-oxygen, imine, and thiourea linkages, respectively. When the excitation and emission wavelengths of each fluorescent probe were controlled, the multi-paths in polyimide aging can be visualized individually and simultaneously in three-dimensional fluorescent images. The overall aging process under hydrothermal treatment was destructured into the pyrolysis and hydrolysis pathways. Three-dimensional dynamic studies discovered that the increased humidity, along with the decreased oxygen content, could hamper the pyrolysis reaction and accelerate the hydrolysis reaction, leading to severe degradation of the overall polyimide aging.

We show that other forms of SA are not detectable with current OPM and propose necessary technical solutions to overcome this circumstance. Our results motivate to pursue OPM-MMG as a new clinical neurophysiological diagnostic.

In addition to enabling remote access to specialized care, telemedicine has also been shown to reduce caregiver burden and to improve patient satisfaction. With the COVID-19 pandemic, implementation of telehealth for patients with movement disorders, particularly those with more severe mobility issues, has increased rapidly. Although telemedicine care has been shown to be effective for patients with various movement disorders, its utilization for patients with device aided therapies such as deep brain stimulation (DBS) is limited due to challenges related to adjusting these devices remotely and to the lack of consensus recommendations for using telemedicine in this patient population. Thus, guidelines for telemedicine and DBS will assist clinicians on the appropriate implementation of telemedicine to provide care to DBS patients. Optimizing the use of telemedicine for DBS will expand this type of therapy to remote locations with limited access to programming expertise, and also reduce the need for patient travel. https://www.selleckchem.com/Androgen-Receptor.html Telemedicine is particularly important during the ongoing pandemic due to infection risk and limited access to clinic visits. In this article we review the currently available and emerging strategies for telemedicine and remote care for DBS. We then outline common principles and recommendations for telemedicine care in patients with DBS, review patient selection and best practices. Finally, we briefly discuss the current state of reimbursement for DBS telemedicine visits. Home-based rapid diagnostic testing can play an integral role in controlling the spread of coronavirus disease 2019 (COVID-19). This review aimed to identify and compare at-home diagnostic tests that have been granted Emergency Use Authorizations (EUAs) and convey details about COVID-19 diagnostic tests, including regulatory information, pertinent to pharmacy practice. The Food and Drug Administration (FDA) online resources pertaining to COVID-19 tests, EUAs, and medical devices were consulted, as were linked resources from FDA's webpages. Homepages of the 9 COVID-19 home tests with EUAs were comprehensively reviewed. PubMed literature searches were performed, most recently in May 2021, to locate literature about the identified home tests, as were searches of Google Scholar, medRxiv, and bioRxiv. Studies were included if they were performed at home or if subjects self-tested at study sites. Samples were collected by a parent or guardian for patients under 18 years of age. Positive percent agreement (PPA SARS-CoV-2 home tests demonstrated satisfactory performance in comparison with laboratory real time reverse-transcription polymerase chain reaction tests. The convenience and ease of use of these tests make them well-suited for home-based rapid SARS-CoV-2 testing.The development of complex forms of multicellular organisms depends on the spatial arrangement of cellular architecture and functions. The interior design of the cell is patterned by spatially biased distributions of molecules and biochemical reactions in the cytoplasm and/or on the plasma membrane. In recent years, a dynamic change in the cytoplasmic fluid flow has emerged as a key physical process of driving long-range transport of molecules to particular destinations within the cell. Here, recent experimental advances in the understanding of the generation of the various types of cytoplasmic flows and contributions to intracellular patterning are reviewed with a particular focus on feedback mechanisms between the mechanical properties of fluid flow and biochemical signaling during animal cell polarization. Young adults have the highest cumulative incidence of COVID-19 infection in the country. Using March 2021 Household Pulse Survey data, an ongoing, cross-sectional nationally representative survey, we examined U.S. young adult intention to accept COVID-19 vaccines. Young adult (ages 18-25 years) Household Pulse Survey participants were queried on intention to receive a COVID-19 vaccine and related perspectives (N= 5,082). Most unvaccinated respondents (76%) indicated an intention to become vaccinated. The most frequently cited reasons for potentially rejecting vaccination included desire to wait and see if the vaccine is safe (56%); concerns over side effects (53%); and believing others are in greater need of the vaccine (44%). With 24% of young adults hesitant to accept a COVID-19 vaccine, public health interventions should target reasons for hesitancy, address concerns about safety and side effects, and underscore the importance of vaccinations for this population. With 24% of young adults hesitant to accept a COVID-19 vaccine, public health interventions should target reasons for hesitancy, address concerns about safety and side effects, and underscore the importance of vaccinations for this population. Early adolescence is an important developmental period where youth take primary responsibility for asthma self-management. Helpful caregiver support during this time is pivotal in determining whether early adolescents successfully develop asthma self-management behaviors. AIM2ACT is a dyadic mobile health intervention designed to increase helpful caregiver support as early adolescents engage in asthma self-management behaviors. We conducted a pilot randomized controlled trial to determine the feasibility and acceptability of AIM2ACT and conduct preliminary tests of efficacy. We randomized adolescents (12-15 years old) and a caregiver to receive AIM2ACT (n= 17) or a self-guided attention control condition (n= 16) for 20weeks. We conducted assessment visits at baseline, postintervention, and 4-month follow-up. Outcomes included family asthma management (primary outcome), adolescent asthma control, lung function (forced expiratory volume in 1second), asthma-related quality of life, asthma management self-efficacy, and family communication.

Dehydroepiandrosterone sulfate (DHEAS) has been reported to be associated with sexual function and general psychological health respectively, however, no one has ever examined their mutual relationships in a single study. The aim of the present study was to find out whether DHEAS, general psychological health, and erectile function were all associated with each other. A cross-sectional study was conducted on 34 patients with erectile dysfunction (ED) and 32 healthy controls (HC). The levels of serum DHEAS were assessed by chemiluminescence method. https://www.selleckchem.com/Bcl-2.html Erectile function and general psychological health were measured by International Index for Erectile Function-5 (IIEF-5) and General Health Questionnaire 20(GHQ-20) respectively. The primary outcome measure of this study wasthe mutual correlations of serum DHEAS levels, general psychological health and erectile function. Compared to HC, patients with ED had a significant lower serum levels of DHEAS (6.43 ± 2.70 μmol/L vs 9.48 ± 2.82 μmol/L, P < .001) antile function seems to be independent of DHEAS.

Sex Med 2021;9100386.The Agrobacterium tumefaciens atu4217 gene, which encodes a TetR family transcription regulator, is a repressor of the atu4218-atu4219-atu4220 operon. The Atu4218 and Atu4219 proteins belong to the HlyD family (membrane fusion protein) and the AcrB/AcrD/AcrF family (inner membrane transporter), respectively, and may form an efflux pump. The atu4220 gene encodes a short-chain dehydrogenase. Quantitative real-time PCR analysis showed induction of atu4217 and atu4218 by NaOCl but not by N-ethylmaleimide or reactive oxygen species (ROS) including H2O2, menadione and cumene hydroperoxide; therefore, the atu4218 and atu4219 were named NaOCl-inducible efflux genes nieA and nieB, respectively. The atu4217 gene, which was named nieR, serves as a repressor of nieA and nieB. DNase I footprinting assays identified 20-bp imperfect inverted repeat (IR, underlined) motifs 5'-TAGATTTAGGATGCAATCTA-3' (box A) and 5'-TAGATTTCACTTGACATCTA-3' (box R) in the intergenic region of the divergent nieA and nieR genes; these motifs were recognized by the NieR protein. Electrophoretic mobility shift assays demonstrated that NieR specifically binds to the 20-bp IR motifs and that NaOCl prevents this NieR-DNA interaction. Promoter-lacZ fusions and mutagenesis of the NieR boxes (A and R) showed a more dominant role for box A than for box R in the repression of the nieA and nieR promoters. However, full repression of either promoter required both operators. The nieR mutant strain exhibited a small colony phenotype and was more sensitive than the wild-type to NaOCl and antibiotics, including ciprofloxacin, nalidixic acid, novobiocin, and tetracycline. By contrast, the nieAB mutant strain showed no phenotype changes under the tested conditions.The natural moisturizing factor (NMF) is a mixture of small water-soluble compounds present in the upper layer of the skin, stratum corneum (SC). Soaking of SC in water leads to extraction of the NMF molecules, which may influence the SC molecular properties and lead to brittle and dry skin. In this study, we investigate how the molecular dynamics in SC lipid and protein components are affected by the removal of the NMF compounds. We then explore whether the changes in SC components caused by NMF removal can be reversed by a subsequent addition of one single NMF component urea, pyrrolidone carboxylic acid (PCA) or potassium lactate. Samples of intact SC were investigated using NMR, X-ray diffraction, infrared spectroscopy and sorption microbalance. It is shown that the removal of NMF leads to reduced molecular mobility in keratin filaments and SC lipids compared to untreated SC. When the complex NMF mixture is replaced by one single NMF component, the molecular mobility in both keratin filaments and lipids is regained. From this we propose a general relation between the molecular mobility in SC and the amount of polar solutes which does not appear specific to the precise chemical identify of the NMF compounds.Membrane fouling is an ongoing challenge in the membrane filtration process. Herein, a photocatalytic membrane comprising a reactive layer was fabricated by engineering partially reduced graphene oxide/Ag nanoparticles/MIL-88A (prGO/Ag/M88A, pGAM) photocatalysts on the PVDF substrate membranes. Benefiting from the high conductivity of prGO and the surface plasmon resonance (SPR) effect of Ag nanoparticles (Ag NPs), the photo-sensitivity of the prGO/Ag/M88A is significantly enhanced. Compared to the membrane in the dark condition, the pGAM membrane displayed an enhanced dye removal efficiency (∼99.7%) and significantly improved permeability (∼189 L·m-2·h-1 bar-1) towards dye contaminants based on the synergistic filtration/photo-Fenton processes. Significantly, the membrane retained high perm-selectivity after 10 cyclic runs (183 L·m-2·h-1 bar-1 of permeability and 98.1% of dye removal), and its nano-channel structure did not collapse under high pressure (0.1-0.4 MPa). The membrane also exhibits antifouling properties with a high water flux recovery of more than 90%. In addition, the pGAM membrane exhibited a high MB degradation efficiency (∼90%) when it is directly used as a photocatalyst in the photo-Fenton system. The mechanism of the self-cleaning is also proposed through quenching experiments. The results of this study demonstrate that this self-cleaning membrane has huge promise for membrane anti-fouling and wastewater remediation.Developing electrocatalysts with excellent catalytic performance and superior durability for hydrogen evolution reaction (HER) remains a challenge. Herein, metal-nitrogen sites (M-Nx, M = Ni and Cu) are successfully implanted into zeolitic imidazolate zinc framework (ZIF-8)-derived nitrogen-doped porous carbon (ZIF/NC) to prepare Ni-ZIF/NC and Cu-ZIF/NC electrocatalysts for the HER. These M-Nx active sites significantly enhanced the electrocatalytic activities of Ni-ZIF/NC and Cu-ZIF/NC. Metal Ni acted as a catalyst for catalysis of Ni-ZIF/NC to form carbon nanotubes-like structures, which provided convenient ion transmission pathways. Owing to its special morphology and an increased number of defects, Ni-ZIF/NC displayed superior electrocatalytic activity in the HER compared to those of Cu-ZIF/NC and ZIF/NC. In an alkaline environment, Ni-ZIF/NC exhibited an overpotential at the current density of 10 mA cm-2 (η10) of 163.0 mV and Tafel slope of 85.0 mV dec-1, demonstrating an electrocatalytic property equivalent to that of Pt/C.
