Thiyl radicals are important reactive sulfur species and can cause cis to trans isomerization on unsaturated fatty acids. However, biocompatible strategies for the controlled generation of thiyl radicals are still lacking. In this work, we report the study of a series of naphthacyl-derived thioethers as photo-triggered thiyl radical precursors.

Unlabelled: A novel Hendra virus (HeV) genotype (HeV genotype 2 [HeV-g2]) was recently isolated from a deceased horse, revealing high-sequence conservation and antigenic similarities with the prototypic strain, HeV-g1. As the receptor-binding (G) and fusion (F) glycoproteins of HeV are essential for mediating viral entry, functional characterization of emerging HeV genotypic variants is key to understanding viral entry mechanisms and broader virus-host co-evolution. We first confirmed that HeV-g2 and HeV-g1 glycoproteins share a close phylogenetic relationship, underscoring HeV-g2's relevance to global health.

Understanding the fundamental biochemical and metabolic requirements for the replication of coronaviruses within infected cells is of notable interest for the development of broad-based therapeutic strategies, given the likelihood of the emergence of new pandemic-potential virus species, as well as future variants of SARS-CoV-2. Here we demonstrate members of the glutaminase family of enzymes (GLS and GLS2), which catalyze the hydrolysis of glutamine to glutamate (i.e.

Background: Hyperbaric oxygen therapy (HBOT) increases oxygen concentration in affected tissues that enhance the cellular hypoxia recovery process, neovascularization, fibroblast proliferation, increased reactive oxygen species, suppression of proinflammatory states, and vascular compression. The aim of this article is to demonstrate the experience in the use of the hyperbaric chamber as an adjunctive management for the prompt recovery of patients who underwent aesthetic plastic surgery.

Methods: A retrospective descriptive study was conducted between 2021 and 2023, involving 296 patients who received HBOT after aesthetic surgical procedures, to demonstrate the recuperation time rate and the complication incidence in postoperative patients using HBOT.

Article Synopsis
  • Bats are carriers of deadly zoonotic viruses for humans but seem to tolerate these viruses without becoming ill.
  • Jamaican fruit bats (JFBs) produce weaker antibody responses to viruses compared to laboratory mice, yet show greater B cell receptor (BCR) diversity.
  • Altering the diet of JFBs by restricting protein can enhance their antibody response to certain viruses, but this improvement comes at the cost of reduced BCR diversity.

UV-stabilizers are a class of additives that provide extended polymer resistance to UV-degradation, but have also been suggested to have antimicrobial activity, potentially preventing the spread of pathogens, and inhibiting microbial-induced biodegradation. In this work, we incorporated different UV-stabilizers, a hindered amine light stabilizer (HALS), Tinuvin 770 DF and Tinuvin PA 123, or a hybrid HALS/UV-absorber, Tinuvin 5151, in polyurethane formulations to produce lacquer-films, and tested their antimicrobial activity against (methicillin-resistant and -sensitive strains), and . Lacquer-films incorporated with Tinuvin 770 DF showed strong antimicrobial performance against bacteria and fungi, while maintaining cytocompatibility.

The ancestral gamete fusion protein, HAP2/GCS1, plays an essential role in fertilization in a broad range of taxa. To identify factors that may regulate HAP2/GCS1 activity, we screened mutants of the ciliate for behaviors that mimic knockout phenotypes in this species. Using this approach, we identified two new genes, and , whose products are necessary for membrane pore formation following mating type recognition and adherence.

COVID-19 can cause neurological symptoms such as fever, dizziness, and nausea. However, such neurological symptoms of SARS-CoV-2 infection have been hardly assessed in mouse models. In this study, we infected two commonly used wild-type mouse lines (C57BL/6J and 129/SvEv) and a 129S calcitonin gene-related peptide (αCGRP) null-line with mouse-adapted SARS-CoV-2 and demonstrated neurological signs including fever, dizziness, and nausea.

Introduction: Lipoabdominoplasty is one of the most common abdominal body contouring procedures performed today; however, it carries the risk of significant complications. Pneumothorax is a rare complication of liposuction, while, venous thromboembolism has a low short-term mortality and long-term morbidity.

  • The study investigates genetic alterations in pediatric B-cell Acute Lymphoblastic Leukemia (B-ALL) in Mexican patients, focusing on their impact on prognosis and treatment.
  • A total of 206 patients were analyzed, revealing a notable 21.8% prevalence of specific genetic profiles linked to poorer outcomes and indicating higher risk stratification among the affected.
  • The findings suggest that these genetic markers significantly influence overall survival, with variations in mutation frequency compared to other populations, highlighting the need for genomic considerations in treatment strategies.

  • A new multitarget stool DNA test was developed to enhance colorectal cancer screening by improving specificity and assessing both DNA markers and hemoglobin levels.
  • In a study involving over 20,000 adults aged 40 and older undergoing screening colonoscopy, the test’s sensitivity for colorectal cancer was found to be 93.9% and its specificity for identifying advanced neoplasia was 90.6%.
  • Compared to a standard fecal immunochemical test (FIT), the multitarget test showed significantly higher sensitivity for detecting colorectal cancer and advanced precancerous lesions, although the FIT had slightly better specificity for advanced neoplasia.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is causing the ongoing global pandemic associated with morbidity and mortality in humans. Although disease severity correlates with immune dysregulation, the cellular mechanisms of inflammation and pathogenesis of COVID-19 remain relatively poorly understood. Here, we used mouse-adapted SARS-CoV-2 strain MA10 to investigate the role of adaptive immune cells in disease.

Paramyxoviruses are a family of single-stranded negative-sense RNA viruses, many of which are responsible for a range of respiratory and neurological diseases in humans and animals. Among the most notable are the henipaviruses, which include the deadly Nipah (NiV) and Hendra (HeV) viruses, the causative agents of outbreaks of severe disease and high case fatality rates in humans and animals. NiV and HeV are maintained in fruit bat reservoirs primarily in the family and spillover into humans directly or by an intermediate amplifying host such as swine or horses.

Target proteins that lack accessible binding pockets and conformational stability have posed increasing challenges for drug development. Induced proximity strategies, such as PROTACs and molecular glues, have thus gained attention as pharmacological alternatives, but still require small molecule docking at binding pockets for targeted protein degradation. The computational design of protein-based binders presents unique opportunities to access "undruggable" targets, but have often relied on stable 3D structures or structure-influenced latent spaces for effective binder generation.

Henipaviruses include the deadly zoonotic Nipah (NiV) and Hendra (HeV) paramyxoviruses, which have caused recurring outbreaks in human populations. A hallmark of henipavirus infection is the induction of cell-cell fusion (syncytia), caused by the expression of the attachment (G) and fusion (F) glycoproteins on the surface of infected cells. The interactions of G and F with each other and with receptors on cellular plasma membranes drive both viral entry and syncytia formation and are thus of great interest.

The ancestral gamete fusion protein, HAP2, catalyzes sperm-egg fusion in a broad range of taxa dating to the last eukaryotic common ancestor. Remarkably, HAP2 orthologs are structurally related to the class II fusogens of modern-day viruses, and recent studies make clear that these proteins utilize similar mechanisms to achieve membrane merger. To identify factors that may regulate HAP2 activity, we screened mutants of the ciliate for behaviors that mimic knockout phenotypes in this species.
