Gut Microbiota Dysbiosis in Endometriosis: A Potential Link to Inflammation and Disease Progression

Alexandra Irma Gabriela Bauşic, Francesca Scurtu, Andrei Manu et al. · 2025 · International Journal of Molecular Sciences

Endometriosis is a complex gynaecological disorder characterised by the presence of endometrial-like tissue outside the uterus, leading to chronic inflammation, pain, and infertility. Recent research suggests that gut microbiota may play a crucial role in the pathogenesis and progression of endometriosis by modulating immune responses and oestrogen metabolism. This study investigates the intestinal microbiota composition in women with endometriosis and its potential as a disease diagnosis and severity biomarker. Stool samples from nine patients diagnosed with endometriosis were analysed using

A Smartphone App Self-Management Program for Chronic Obstructive Pulmonary Disease: Randomized Controlled Trial of Clinical Outcomes

Lisa H. Glynn, E Moloney, Stephen Lane et al. · 2025 · JMIR mhealth and uhealth

BACKGROUND: Chronic obstructive pulmonary disease (COPD) negatively impacts clinical health outcomes, resulting in frequent exacerbations, increased hospitalizations, reduced physical activity, deteriorated quality of life, and diminished self-efficacy. Previous studies demonstrated that a self-management program tailored for adults with COPD improves self-management decisions, resulting in a positive effect on clinical health outcomes. Limitations of these studies include issues regarding heterogeneity among interventions used, patient population characteristics, outcome measures, and longitu

Relaxin Does Not Improve Angiotensin II-Induced Target-Organ Damage

Nadine Haase, Julianna Rugor, Łukasz Przybył et al. · 2014 · PLoS ONE

Relaxin is a corpus-luteum produced protein hormone with vasodilatatory, anti-fibrotic, and angiogenic properties that are opposite to angiotensin (Ang) II. We investigated whether or not relaxin ameliorates Ang II-induced target-organ damage. We used double transgenic rats harboring both human renin and angiotensinogen genes (dTGR) that develop severe hypertension, target-organ damage, and die untreated within 7-8 weeks. Recombinant relaxin at a low (26 μg/kg/d) and a high dose (240 μg/kg/d) was given to 4 week-old dTGR and age-matched Sprague-Dawley rats (SD). Systolic blood pressure increas

4-Aminobutyrate Aminotransferase (ABAT): Genetic and Pharmacological Evidence for an Involvement in Gastro Esophageal Reflux Disease

Johan Jirholt, Bengt Åsling, Paul Hammond et al. · 2011 · PLoS ONE

Gastro-esophageal reflux disease (GERD) is partly caused by genetic factors. The underlying susceptibility genes are currently unknown, with the exception of COL3A1. We used three independent GERD patient cohorts to identify GERD susceptibility genes. Thirty-six families, demonstrating dominant transmission of GERD were subjected to whole genome microsatellite genotyping and linkage analysis. Five linked regions were identified. Two families shared a linked region (LOD 3.9 and 2.0) on chromosome 16. We used two additional independent GERD patient cohorts, one consisting of 219 trios (affected

Detection of Two Highly Diverse Peribunyaviruses in Mosquitoes from Palenque, Mexico

Anne Kopp, Alexandra Hübner, Florian Zirkel et al. · 2019 · Viruses

. Orthobunyaviruses and pacuviruses are mainly transmitted by blood-feeding insects and infect a variety of vertebrates whereas herbeviruses and shangaviruses have a host range restricted to insects. Here, we tested mosquitoes from a tropical rainforest in Mexico for infections with peribunyaviruses. We identified and characterized two previously unknown viruses, designated Baakal virus (BKAV) and Lakamha virus (LAKV). Sequencing and de novo assembly of the entire BKAV and LAKV genomes revealed that BKAV is an orthobunyavirus and LAKV is likely to belong to a new genus. LAKV was almost equidis

Evaluation and Application of a PET Tracer in Preclinical and Phase 1 Studies to Determine the Brain Biodistribution of Minzasolmin (UCB0599)

Joël Mercier, Massimo Bani, Anny‐Odile Colson et al. · 2023 · Molecular Imaging and Biology

Abstract Purpose Minzasolmin (UCB0599) is an orally administered, small molecule inhibitor of ASYN misfolding in development as a potential disease-modifying therapy for Parkinson’s disease. Here we describe the preclinical development of a radiolabeled tracer and results from a phase 1 study using the tracer to investigate the brain distribution of minzasolmin. Procedures In the preclinical study, two radiolabeling positions were investigated on the S -enantiomer of minzasolmin (UCB2713): [ 11 C]methylamine UCB2713 ([ 11 C- N -CH 3 ]UCB2713) and [ 11 C]carbonyl UCB2713 ([ 11 C-CO]UCB2713).

Ulinastatin did not reduce mortality in elderly multiple organ failure patients: a retrospective observational study in a single center ICU

Masatoshi Uchida, Toshikazu Abe, Kazuyuki Ono et al. · 2017 · Acute Medicine & Surgery

Aim Our aim was to evaluate the effect of ulinastatin on 28‐day mortality in patients who developed multiple organ failure ( MOF ) related to their acute illness and were admitted to the intensive care unit ( ICU ). Methods We carried out a retrospective observational study of MOF patients in a general ICU of a tertiary care hospital in Japan from January 2009 to December 2012. The primary outcome was 28‐day all‐cause mortality. Secondary outcomes were ventilator‐free days, ICU ‐free days, and vasopressor‐free days at day 28. We investigated the association between ulinastatin treatment and ou

Nonopioid vs opioid analgesics after impacted third-molar extractions

Cecile A. Feldman, Janine Fredericks-Younger, Paul J. Desjardins et al. · 2025 · The Journal of the American Dental Association

BACKGROUND: Opioids are still being prescribed to manage acute postsurgical pain. Unnecessary opioid prescriptions can lead to addiction and death, as unused tablets are easily diverted. METHODS: To determine whether combination nonopioid analgesics are at least as good as opioid analgesics, a multisite, double-blind, randomized, stratified, noninferiority comparative effectiveness trial was conducted, which examined patient-centered outcomes after impacted mandibular third-molar extraction surgery. Participants were randomized to receive 5 mg of hydrocodone with 300 mg of acetaminophen (opioi
