Sexual violence victimization is a prevalent public health concern. However, little research has investigated the factors linking sexual violence victimization to suicidal thoughts and behaviors (STBs). The current study tested the applicability of the psychological mediation framework, a coping-mental health model, for the prevention of STBs among victims of sexual youviolence. mTOR inhibitor cancer Furthermore, the current study explored whether sexual orientation moderated the progression from sexual violence victimization to STBs. Data were drawn from an online survey of victimization experiences and health (N = 2175). link= mTOR inhibitor cancer Bootstrap mediation tested whether the association of sexual violence victimization and STBs was mediated by emotion regulation strategies (cognitive reappraisal and expressive suppression) and psychopathology (anxiety, depression, and posttraumatic stress disorder). Multiple-groups analysis tested whether links within the mediation effects varied by sexual orientation. Bivariate findings showed that (1) sexual minority persons were more likely to report sexual violence victimization and (2) cognitive reappraisal was more meaningfully associated with mental health among sexual minority persons. Sexual violence victimization was associated with STBs via a serial mediation through emotion regulation and psychopathology. The association between psychopathology and STBs was stronger among sexual minority compared with heterosexual respondents. Physical violence victimization was associated with STBs for heterosexual but not sexual minority persons in a follow-up model. Findings support an emotion regulation-mental health framework for the prevention of suicide among victims of sexual violence. link2 Research and training implications are discussed.Violent video game playing is a consistent risk factor for aggression, but research on its psychopathology and trait underpinnings are primarily based on community or university student samples, thus the ecological validity to adjudicated and juvenile justice system-involved youth lacks clarity. This is an important void in the literature because relative to youth in the general population, adjudicated and detained youth evince greater psychopathology, more severe delinquency and violence histories, and clinical psychopathic features. Negative binomial regression models using data from 252 youth in residential placements found that several psychopathic features are significantly associated with violent video gaming. The role of psychopathy operated differently across gender and arrest chronicity, and across models remorselessness emerged as an important correlate. Given the desensitization that can occur with violent video game play, it is of particular concern among delinquent youth with psychopathic personality features.Heavy metal toxicity is one of the major concerns for agriculture and health. Accumulation of toxic heavy metals at high concentrations in edible parts of crop plants is the primary cause of disease in humans and cattle. A dramatic increase in industrialization, urbanization, and other high anthropogenic activities has led to the accumulation of heavy metals in agricultural soil, which has consequently disrupted soil conditions and affected crop yield. By now, plants have developed several mechanisms to cope with heavy metal stress. However, not all plants are equally effective in dealing with the toxicity of high heavy metal concentrations. Plants have modified their anatomy, morphophysiology, and molecular networks to survive under changing environmental conditions. Heavy metal sequestration is one of the essential processes evolved by some plants to deal with heavy metals' toxic concentration. Some plants even have the ability to accumulate metals in high quantities in the shoots/organelles without toxic effects. For intercellular and interorganeller metal transport, plants harbor spatially distributed various transporters which mainly help in uptake, translocation, and redistribution of metals. This review discusses different heavy metal transporters in different organelles and their roles in metal sequestration and redistribution to help plants cope with heavy metal stress. link3 link2 A good understanding of the processes at stake helps in developing more tolerant crops without affecting their productivity.Protein accumulation is the hallmark of various neuronal, muscular, and other human disorders. It is also often seen in the liver as a major protein-secretory organ. For example, aggregation of mutated alpha1-antitrypsin (AAT), referred to as PiZ, is a characteristic feature of AAT deficiency, whereas retention of hepatitis B surface protein (HBs) is found in chronic hepatitis B (CHB) infection. We investigated the interaction of both proteotoxic stresses in humans and mice. Animals overexpressing both PiZ and HBs (HBs-PiZ mice) had greater liver injury, steatosis, and fibrosis. Later they exhibited higher hepatocellular carcinoma load and a more aggressive tumor subtype. mTOR inhibitor cancer Although PiZ and HBs displayed differing solubility properties and distinct distribution patterns, HBs-PiZ animals manifested retention of AAT/HBs in the degradatory pathway and a marked accumulation of the autophagy adaptor p62. Isolation of p62-containing particles revealed retained HBs/AAT and the lipophagy adapter perilipin-2. p62 build-up led to activation of the p62-Nrf2 axis and emergence of reactive oxygen species. Our results demonstrate that the simultaneous presence of two prevalent proteotoxic stresses promotes the development of liver injury due to protein retention and activation of the p62-Nrf2 axis. In humans, the PiZ variant was over-represented in CHB patients with advanced liver fibrosis (unadjusted odds ratio = 9.92 [1.15-85.39]). Current siRNA approaches targeting HBs/AAT should be considered for these individuals. link3 © 2021 The Authors.

Ecologists have measured thousands of predator functional responses using the same basic experimental method. However, this design is ill-suited to address many current questions regarding functional responses. We derive a new experimental design and statistical analysis that quantifies functional responses using the times between a predators' feeding events requiring only one or a few trials. We examine the feasibility of the experimental method and analysis using simulations to assess the ability of the statistical model to estimate functional response parameters and perform a proof-of-concept experiment estimating the functional responses of two individual jumping spiders. Our simulations show that the statistical method reliably estimates functional response parameters. Our proof-of-concept experiment illustrates that the method provides reasonable estimates of functional response parameters. By virtue of the fewer number of trials required to measure a functional response, the method derived here promises to expand the questions that can be addressed using functional response experiments and the systems in which they can be measured. Thus, we hope that our method will refine our understanding of functional responses and predator-prey interactions more generally.

Nonalcoholic fatty liver disease (NAFLD) affects 25% of the global population. The standard of diagnosis, biopsy, is invasive and affected by sampling error and inter-reader variability. We hypothesized that widely available rapid MRI techniques could be used to predict nonalcoholic steatohepatitis (NASH) noninvasively by measuring liver stiffness, with magnetic resonance elastography (MRE), and liver fat, with chemical shift-encoded (CSE) MRI. Besides, we validate an automated image analysis technique to maximize the utility of these methods.

2 TECHNICAL EFFICACY STAGE 2.The presence of critical coronary artery disease and concomitant critical limb ischemia represents a clinical challenge. Single-stage operations for cardiac and peripheral revascularization can be an option in such cases. The "Süzer technique" provides a more physiological extra-anatomical vascular reconstruction by using the descending thoracic aorta as the inflow source. This is an alternative to the more widely used technique of ascending aorta to bifemoral bypass and concomitant coronary revascularization. We report a case of critical limb ischemia with juxtrarenal aortic occlusion and left main coronary artery stenosis treated with concomitant coronary artery bypass grafting and descending thoracic aorto-bi-iliac bypass using a modification of the Süzer technique.Plants control water-use efficiency (WUE) by regulating water loss and CO2 diffusion through stomata. Variation in stomatal control has been reported among lineages of vascular plants, thus giving rise to the possibility that different lineages may show distinct WUE dynamics in response to water stress. Here, we compared the response of gas exchange to decreasing leaf water potential among four ferns and nine seed plant species exposed to a gradually intensifying water deficit. The data collected were combined with those from 339 phylogenetically diverse species obtained from previous studies. In well-watered angiosperms, the maximum stomatal conductance was high and greater than that required for maximum WUE, but drought stress caused a rapid reduction in stomatal conductance and an increase in WUE in response to elevated concentrations of abscisic acid. However, in ferns, stomata did not open beyond the optimum point corresponding to maximum WUE and actually exhibited a steady WUE in response to dehydration. Thus, seed plants showed improved photosynthetic WUE under water stress. The ability of seed plants to increase WUE could provide them with an advantage over ferns under drought conditions, thereby presumably increasing their fitness under selection pressure by drought.Abnormalities of the tumor vasculature result in insufficient blood supply and development of a tumor microenvironment that is characterized by low glucose concentrations, low extracellular pH, and low oxygen tensions. We previously reported that glucose-deprived conditions induce metabolic stress and promote tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-induced cytotoxicity. In this study, we examined whether the metabolic stress-associated endoplasmic reticulum (ER) stress response pathway plays a pivotal role in the enhancement of TRAIL cytotoxicity. We observed no significant cytotoxicity when human colorectal cancer SW48 cells were treated with various doses of TRAIL (2-100 ng/ml) for 4 h or glucose (0-25 mM) for 24 h. However, a combination of TRAIL and low glucose-induced dose-dependent apoptosis through activation of caspases (-8, -9, and -3). Studies with activating transcription factor 4 (ATF4), C/EBP-homologous protein (CHOP), p53 upregulated modulator of apoptosis (PUMA), or death receptor 5 (DR5)-deficient mouse embryonic fibroblasts or HCT116 cells suggest that the ATF4-CHOP-PUMA axis and the ATF4-CHOP-DR5 axis are involved in the combined treatment-induced apoptosis.
