atment for overhead athletes. Recent studies evaluating the biomechanical properties as well as clinical outcomes have demonstrated favorable data when UCL repair is performed. When considering the drawbacks of a prolonged recovery associated with reconstruction, UCL repair is a viable option in select patients.Micrurus surinamensis is a coral snake from the Elapidae family of wide distribution in Amazonia Forest. Its venom contains neurotoxins that induce muscular and respiratory paralysis; however, its cardiovascular action is not yet characterized. The aim of this study was to investigate the cardiotoxic effects caused by M. surinamensis poisoning in rodents. Twelve guinea pigs (Cavia porcellus) were distributed in two groups (n = 6) named as control and envenomed. The control group received 0.2 ml of PBS/BSA via intramuscular injection (IM), while envenomed animals received 0.75 µg of venom per g of body weight, also via IM. Electrocardiographic examination (ECG) and biochemical serum tests were conducted before and 2 h after inoculation. ECG of the envenomed animals revealed severe progressive arrhythmias including atrioventricular block, supraventricular, and ventricular extrasystoles. Serum biochemistry showed significant increase in CK, CK-MB, and LDH enzymes corroborating the skeletal and cardiac muscle damage. Myonecrosis and degeneration were observed in both skeletal and heart muscle; nevertheless, transmission electron microscopy revealed cardiac muscle fibers fragmentation. In conclusion, M. surinamensis venom has a potent cardiotoxic activity eliciting arrhythmogenic effects and heart damage after only 2 h of envenomation.The structural protein VP3 of infectious bursal disease virus (IBDV) plays a critical role in viral assembly, replication, immune escape, and anti-apoptosis. Interaction between VP3 and host protein factors can affect stages in the viral replication cycle. In this study, 137 host proteins interacting with VP3 protein were screened through liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based proteomics approach. The functions and relevance of the proteins were obtained through bioinformatics analysis. Most VP3-interacting proteins were linked to binding, catalytic activity, and structural molecular activity, and performed functions in cell parts and cells. Biological functions of VP3-interacting proteins were mainly relevant to "Cytoskeleton", "Translation", and "Signal transduction mechanisms", involving ribosomes, "Tight junction", regulation of actin cytoskeleton, and other pathways. Six potential VP3-interacting proteins in host cells were knocked down, and vimentin, myosin-9, and annexin A2 were found to be related to IBDV replication. This study would help explore regulatory pathways and cellular mechanisms in IBDV-infected cells, and also provided clues for the in-depth study of VP3 biological functions and IBDV replication or pathogenesis.A walrus (Odobenus rosmarus) born in an aquarium and hand-reared in Japan died at the age of 11 months. The affected animal showed fever and anorexia and had high levels of AST and ALT. Necropsy showed multiple necroses in the liver and adrenal glands and histological examination revealed necrotic lesions of the liver and adrenal cortex, both of which contained intranuclear inclusions. Electron microscopic analysis of the liver sample showed herpesvirus-like particles. High-throughput sequencing analysis of the liver sample and phylogenetic analysis of herpesvirus polymerase genes identified a new virus, Walrus alphaherpesvirus 1 (WaHV-1), which belonged to the subfamily Alphaherpesvirinae and had high homology with Phocid alphaherpesvirus 1. Phylogenetic analysis of the UL30 gene encoding glycoprotein B revealed that WaHV-1 was closely related to a cluster of phocid herpesviruses, including one that caused high mortality rates in harbor seals during past outbreaks. The mother walrus of the dead animal showed evidence of herpesvirus infection in the past and potentially harbored WaHV-1. As a result of hand-rearing, the dead animal might have acquired WaHV-1 from its infected mother and succumbed to WaHV-1 due to lack of maternal IgG, including those that could neutralize WaHV-1.Members of the Cell Stress Society International (CSSI), Patricija van Oosten-Hawle (University of Leeds, UK), Mehdi Mollapour (SUNY Upstate Medical University, USA), Andrew Truman (University of North Carolina at Charlotte, USA) organized a new virtual meeting format which took place on November 5-6, 2020. The goal of this congress was to provide an international platform for scientists to exchange data and ideas among the Cell Stress and Chaperones community during the Covid-19 pandemic. Here we will highlight the summary of the meeting and acknowledge those who were honored by the CSSI.
While stroke is already considered a nutrition-related disease, the prevalence of the broad array of disordered eating behaviors is under-reported in this disease. We describe the case of a stroke in a young woman following a recent food addiction to fatty-sweet food.

She was diagnosed with a Night-Eating-Syndrome, with a loss-of-control exclusively towards sugary carbohydrates used to manage her insomnia and distress, and her consummatory behaviors were investigated.

This case report illustrates a self-medication of a significant psychological distress by shifting from a healthy diet to an overconsumption of hyper-palatable foods, triggering an addiction disorder. The related hypertriglyceridemia, on top of chronic smoking, contributed to the development of an atherosclerotic plaque and thrombus formation.

Food addiction might be considered as an emerging stroke risk factor. We suggest it fosters the need to take into consideration addictive-like eating behaviors and associated mental disorders in the primary and secondary prevention of stroke. This may be particularly relevant for the prevention of stroke in women as they are more prone to comfort their emotions with food.

People with eating disorders (EDs) have difficulties understanding their own emotions and recognizing the emotions of others, especially in ambiguous settings. We examined the neuronal mechanisms underlying the emotion processing of ambiguous interpersonal stimuli in EDs and healthy controls (HCs).

The fMRI data were acquired by a blocked experimental design with 28 women (14 EDs) during the visual presentation of a modified Thematic Apperception Test.

EDs showed very strong associations between experienced and inferred emotions evoked by the stimuli; no such relationship was found in HCs. HCs displayed elevated left anterior insula activity during the mentalizing condition; EDs showed increased activity in the right supramarginal gyrus and medial prefrontal cortex.

The two groups seem to apply different strategies for judging emotionally ambiguous stimuli, albeit resulting in equivalent judgments. We assume that activity in the supramarginal gyrus and insula in EDs is linked with suppressing their own perspective while considering emotional states, probably due to alexithymia and the lack of awareness of their own mental states. We hypothesize that the strong correlation between experienced and inferred emotions in EDs could reflect their tendency to use others as a reference point for perceiving themselves and gaining information about their affective state.

To evaluate spectral domain optical coherence tomography (SD-OCT) findings of 42 eyes with pars planitis and to identify risk factors affecting visual acuity.

Medical records and SD-OCT findings were retrospectively reviewed.

Mean best-corrected visual acuity (BCVA) was 0.248 ± 0.3 on the logMAR scale at baseline. SD-OCT findings included epiretinal membrane (ERM) in 16 (38.1%) eyes, loss of normal foveal contour appearance in 8 (19.0%), ellipsoid zone (EZ) damage in 5 (11.9%), external limiting membrane (ELM) damage in 3 (7.1%), disruption of retinal pigment epithelium (RPE) in 2 (4.8%), and macular atrophy in 1 (2.4%). There was macular edema in 10 (23.8%) eyes [cystoid macular edema (CME) in 8 (19.0%), diffuse macular edema (DME) in 6 (14.3%), and serous retinal detachment in 2 (4.8%)]. The mean central macular thickness (CMT) was 272.1 ± 319.5μm. Patients were followed up for a mean of 50.6 ± 36.7months. Mean BCVA was 0.210 ± 0.3 at the final evaluation. SD-OCT findings included ERM in 28 (66.7%) eyes, EZ damage in 6 (14.3%), ELM damage in 3 (7.1%), disruption of RPE in 4 (9.5%), loss of normal foveal contour appearance in 12 (28.6%), and macular atrophy in 2 (4.8%). There was CME and/or DME in 6 (14.3%) eyes. The mean CMT was 238 ± 220.9μm and was significantly lower than the baseline (p < 0.001). According to multivariate linear regression analysis, the presence of DME, and loss of normal foveal contour appearance at baseline were the independent factors associated with BCVA at the final examination (B = 0.726, p < 0.001; B = 0.766, p < 0.001, respectively).

DME and loss of normal foveal contour appearance were more likely to have adverse effects on visual acuity.

Our study assessed attenuated recombinant RSVs as vaccine candidates to prevent RSV infection in mice. The constructed recombinant plasmids harbored (5' to 3') a T7 promoter, hammerhead ribozyme, RSV Long strain antigenomic cDNA with cold-passaged (cp) mutations or cp combined with temperature-sensitive attenuated mutations from the A2 strain (A2cpts) or further combined with SH gene deletion (A2cptsΔSH), HDV ribozyme (δ), and a T7 terminator. These vectors were subsequently co-transfected with four helper plasmids encoding N, P, L, and M2-1 viral proteins into BHK/T7-9 cells, and the recovered viruses were then passaged in Vero cells. The rescued recombinant RSVs (rRSVs) were named rRSV-Long/A2cp, rRSV-Long/A2cpts, and rRSV-Long/A2cptsΔSH, respectively, and stably passaged in vitro, without reversion to wild type (wt) at sites containing introduced mutations or deletion. Although rRSV-Long/A2cpts and rRSV-Long/A2cptsΔSH displayed temperature-sensitive (ts) phenotype in vitro and in vivo, all rRSVs were significantly attenuated in vivo. Furthermore, BALB/c mice immunized with rRSVs produced Th1-biased immune response, resisted wtRSV infection, and were free from enhanced respiratory disease. We showed that the combination of ΔSH with attenuation (att) mutations of cpts contributed to improving att phenotype, efficacy, and gene stability of rRSV. By successfully introducing att mutations and SH gene deletion into the RSV Long parent and producing three rRSV strains, we have laid an important foundation for the development of RSV live attenuated vaccines.This study aimed to explore the effects and function of microRNA-101a-3p (miR-101a-3p) in epilepsy. Rat model of pilocarpine-induced epilepsy was established and the seizure frequency was recorded. Expression of miR-101a-3p and c-Fos in hippocampus tissues of Rat models were detected by qRT-PCR and western blot. Besides, we established a hippocampal neuronal culture model of acquired epilepsy using Mg2+ free medium to evaluate the effects of miR-101a-3p and c-Fos in vitro. click here Cells were transfected with miR-101a-3p mimic, si-c-FOS, miR-101a-3p + c-FOS and its corresponding controls. MTT assay was used to detect cell viability upon transfection. Flow cytometry was performed to determine the apoptosis rate. Western blot was performed to measure the protein expression of apoptosis-related proteins (Bcl-2, Bax, and cleaved caspase 3), autophagy-related proteins (LC3 and Beclin1) and c-FOS. The targeting relationship between miR-101a-3p and c-FOS was predicted and verified by TargetScan software and dual-luciferase reporter assay.
