Time-Resolved Metabolomics Reveals Mitochondrial Protection in Septic Liver Injury

Background/Objectives: Sepsis is a life-threatening condition characterized by organ dysfunction due to a dysregulated host response to infection. Mitochondrial dysfunction is considered a key contributor to the pathogenesis of sepsis, but its molecular mechanisms remain unclear. Methods: In this study, we used a cecal ligation and puncture (CLP) model to induce sepsis in wild-type (WT) and cyclop

From prevalent to personal: how social exposure predicts attitudes toward non-suicidal self-injury and what prevalence reveals

Introduction: Non-suicidal self-injury (NSSI) is often met with stigma, which can deter individuals from seeking help. While most research on NSSI stigma has focused on clinical settings, the attitudes of those most likely to receive an NSSI disclosure, such as peers, friends, and family, remain underexplored. Building on qualitative findings that positive disclosure experiences can foster support

Development of the Direct Deuteration Method for Amino Acids and Characterization of Deuterated Tryptophan

Proteins and peptides are vital biomolecules, and deuterated amino acids are increasingly applied in areas such as drug discovery, metabolic tracing, and neutron scattering studies. In this study, we performed deuteration on all 20 proteinogenic amino acids, including their side chains, and established efficient methods for 13 amino acids. Using a Pt/C-catalyzed hydrogen–deuterium exchange reactio

Brief empathy interventions online can decrease but not increase empathic tendencies

People often feel less empathy towards outgroup compared to ingroup targets. Overcoming this intergroup empathy bias is important for fostering positive intergroup relations. In five pre-registered and high-powered online studies (n = 4776 (745/745/1056/1236/994)), we attempted to replicate and generalize motivated empathy interventions that previously have made people more empathetic and prosociaPeople often feel less empathy towards outgroup compared to ingroup targets.

High-dose romosozumab promoted bone regeneration of critical-size ulnar defect filled with demineralized bone matrix in nonhuman primates

Background: Large bone defects are challenging to manage clinically and usually require treatment with bone graft or bone graft substitute. This study evaluated the effect of romosozumab, a sclerostin antibody, in combination with demineralized bone matrix (DBM) on bone regeneration in a critical-size ulnar defect model in nonhuman primates. Methods: In cynomolgus monkeys (N = 22, male, 10–12 year

Drosophila hamlet mediates epithelial tissue assembly of the reproductive system.

Epithelial tissue fusion requires coordinated molecular events at the ends of two epithelial structures. Regulatory mechanisms controlling these events remain largely elusive. In the Drosophila reproductive system (RS), this fusion unites the gonad and the genital disc-derived tissues, into a continuous tube. This study unveils the pivotal role of Hamlet (Ham), a Drosophila PR domain containing

The best fixation target revisited : New insights from retinal eye tracking

In many tasks, participants are instructed to fixate a target. While maintaining fixation, the eyes nonetheless make small fixational eye movements, such as microsaccades and drift. Previous work has examined the effect of fixation point design on fixation stability and the amount and spatial extent of fixational eye movements. However, much of this work used video-based eye trackers, which have i

Early diagnosis of acute myocardial infarction via hub genes identified by integrated weighted gene co-expression network analysis

Background: Acute myocardial infarction (AMI) is a leading cause of morbidity and mortality worldwide. Circulating endothelial cells (CECs) have been reported to be involved with the early stages of AMI. The specific objective of our study was to discover early diagnostic markers of CECs in circulation using bioinformatics analysis. Methods: Raw microarray data of the GSE66360 dataset were acquire

Injury rates following conducted electrical weapons and other less-lethal force modalities in real-life police settings : a comparative literature review

The aim of this study was to rank the rate and risk ratio of subject injury following exposure to less-lethal force modalities in real-life police interventions. The purpose was to observe whether the use of conductive electrical weapons (CEW) qualifies as a low-risk modality of force, with a similar risk of adverse health outcomes as exposure to other less-lethal modalities, such as physical forc

Healthcare Use and Non-Recovery in Patients With Spinal Disorders

Background: The association between different patterns of healthcare use and non-recovery in patients with spinal disorders is unclear. We aimed to assess the association between healthcare use and non-recovery 6 months after a specialist evaluation in Norwegian secondary care and whether non-recovery was linked to adherence to specialist-recommended care. Methods: This observational registry-base

Nutritional outcomes and impact of malnutrition in a randomised comparison between standard and prolonged time to surgery after neoadjuvant chemoradiotherapy for oesophageal cancer

Background: Prolonged time to surgery (TTS) after neoadjuvant chemoradiotherapy (nCRT) may enable malnourished oesophageal cancer patients' nutritional status to recover better, possibly improving outcomes with fewer complications and better overall survival (OS) after oesophagectomy. Methods: This is a substudy within a multicentre randomised controlled trial comparing outcomes in patients with o

Three-dimensional ultrastructural characterization of Drosophila melanogaster hygrosensilla across humidity conditions

Understanding how organisms detect environmental humidity remains a fundamental problem in sensory biology. While specialised sensory neurons in insect antennae can detect changes in humidity, the mechanism underlying this ability is not fully understood. Here, we present an integrated approach combining precise humidity control, rapid cryo-preservation, and serial block-face scanning electron mic

Urban practice in extremis : Resettlement policy, life-threatening housing, and social change in Mumbai

Cities today grapple with crises of inequality, governance, and environmental challenges. Scholarship must also adapt to these evolving issues by developing new practices and generating relevant scholarship. This article examines a case of ‘social extremis’—severe socio-political conditions that threaten or limit life—and explores social practices that challenge such conditions. The study focuses

Dietary Modifications in IBS Leads to Reduced Symptoms, Weight, and Lipid Levels : Two Randomized Clinical Trials

Background/Objectives: Irritable bowel syndrome (IBS) is presented with both gastrointestinal and extraintestinal symptoms. In addition, overweight/obesity and metabolic syndrome is prevalent in IBS. Dietary interventions with a low content of fermentable oligo-, di-, and monosaccharides and polyols (FODMAP) or a starch- and sucrose-reduced diet (SSRD) efficiently reduce symptoms and weight. Our h

A Reinforcement Learning Approach Based on Group Relative Policy Optimization for Economic Dispatch in Smart Grids

The Economic Dispatch Problem (EDP) plays a critical role in power system operations by trying to allocate power generation across multiple units at minimal cost while satisfying complex operational constraints. Traditional optimization techniques struggle with the non-convexities introduced by factors such as valve-point effects, prohibited operating zones, and spinning reserve requirements. Whil

A Comprehensive Review of the Epidemiology, Pathophysiology, Risk Factors, and Treatment Strategies for Retinoblastoma

The retinoblastoma gene (RB1), which is located on chromosome 13q14.2, is mutated in retinoblastoma (RB), the most common malignant intraocular tumor in children. About 8000 new cases of retinoblastoma are diagnosed globally each year, accounting for approximately 1 in 17,000 live births. RB is prototypically considered hereditary by nature as thirty to forty percent of cases have autosomal domina
