Key bacterial vaginosis-associated bacteria influence each other's growth in biofilms in rich media and media simulating vaginal tract secretions.

Biofilm

June 2025

Centre of Biological Engineering (CEB), Laboratory of Research in Biofilms Rosário Oliveira (LIBRO), University of Minho, Braga, Portugal.

Bacterial vaginosis (BV) is a very common gynaecologic condition affecting women of reproductive age worldwide. BV is characterized by a depletion of lactic acid-producing species and an increase in strict and facultative anaerobic bacteria that develop a polymicrobial biofilm on the vaginal epithelium. Despite multiple decades of research, the etiology of this infection is still not clear.

is a Gram-positive bacterium, also known as Group A (GAS), that has become a significant threat to the healthcare system, infecting more than 18 million people and resulting in more than 500,000 deaths annually worldwide. GAS infection rates decreased gradually during the 20th century in Western countries, largely due to improved living conditions and access to antibiotics. However, post-COVID-19, the situation has led to a steep increase in GAS infection rates in Europe, the United States, Australia, and New Zealand, which triggers a global concern.

Distinct role of primate DLPFC and LIP in hierarchical control of learned saccade sequences.

iScience

January 2025

Key Laboratory of Brain Functional Genomics (Ministry of Education), East China Normal University, Shanghai 200062, China.

Learned action sequences are suggested to be organized hierarchically, but how the various hierarchical levels are processed by different cortical regions remains largely unknown. By training monkeys to perform heterogeneous saccade sequences, we investigated the role of the dorsolateral prefrontal cortex (DLPFC) and the lateral intraparietal cortex (LIP) in sequence planning and execution. The electrophysiological recording revealed that sequence-level initiation information was mostly signaled by DLPFC neurons, whereas subsequence-level transition was largely encoded by LIP neurons.

While many chemicals are regulated and routinely monitored in drinking water, they represent just a portion of all contaminants that may be present. Typical drinking water analyses involve sampling one liter or less of water, which could lead to trace level contaminants going undetected. In this study, a method was developed for using point-of-use activated carbon block drinking water filters as sampling devices.

Altered protein conformation can cause incurable neurodegenerative disorders. Mutations in , the gene encoding neuroserpin, can alter protein conformation resulting in cytotoxic aggregation leading to neuronal death. Familial encephalopathy with neuroserpin inclusion bodies (FENIB) is a rare autosomal dominant progressive myoclonic epilepsy that progresses to dementia and premature death.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heritable myocardial condition that mostly affects the right ventricle (RV). Atrial involvement is poorly understood and the evidence for atrial involvement remains limited. In this case report, we describe an 18-year-old woman who had ARVC with the atrial tachyarrhythmia and initially presented with palpitations.

Exclusionary bargaining behavior in 14 countries: Prevalence and predictors.

PNAS Nexus

January 2025

Department of Political Science, Aarhus University, Bartholins Allé 7, Aarhus 8000, Central Denmark Region, Denmark.

Primates are known to engage in exclusionary behavior, forming alliances to block a minority from accessing scarce resources. Humans are no exception, and examples of exclusionary behavior abound in political, business, and social settings. However, despite its socio-economic relevance, little is known about the prevalence and determinants of such behavior worldwide.

Opioid dependence can occur in 6% to 10% of patients undergoing breast reconstruction. With the expansion of interdisciplinary initiatives to decrease opioid use after surgery, an updated look at the incidence of and risk factors for prolonged opioid dependence after free flap breast reconstruction is essential. We retrospectively identified all cases of free flap breast reconstruction completed at our institution from 2017 to 2020.

A Narrative Persuasion Approach to Promoting COVID-19- Related Policy Support.

J Health Commun

January 2025

School of Criminal Justice, Forensic Science, and Security, University of Southern Mississippi, Hattiesburg, Mississippi, USA.

Communication scholars warn against focusing on individual behaviors when discussing health issues, arguing that doing so can reduce affect and policy support. Although COVID-19 outcomes are linked to structural barriers to treatment, policy interventions appear to improve outcomes for vulnerable groups. Thus, strategic messages must promote public understanding of social determinants and policy support related to COVID-19.

Objective: Sensory phenomena (SP) are aversive sensations driving repetitive behaviors in obsessive-compulsive disorder (OCD) and Tourette's disorder that are not well addressed by standard treatments. SP are related to the functioning of an interoceptive-sensorimotor circuit that may be modulated by the 5-HT receptor antagonist ondansetron. The present study employed an experimental medicine approach to test the effects of 4 weeks of high-dose ondansetron compared to placebo on SP severity and brain connectivity in a cohort of individuals with OCD and/or Tourette's disorder.

A tandem catalytic ensemble of solid-state molecular organometallic (SMOM) crystalline pre-catalysts are deployed under batch or flow conditions for the ethene to propene process (ETP). These catalysts operate at ambient temperature and low pressure, via sequential ethene dimerization, butenes isomerization and cross-metathesis. Under flow conditions the on-stream ethene conversion (55%), initial propene selectivity (92%), stability (71% selectivity after 7 hrs) and low temperature/pressures are competitive with the best-in-class heterogenous systems, marking a new, in crystallo, approach to ETP.

Use of Resonant Acoustic Fields as Atmospheric-Pressure Ion Gates.

Anal Chem

January 2025

Department of Chemistry and Chemical Biology, Rensselaer Polytechnic Institute, Troy, New York 12180, United States.

Ion optics are crucial for spectrometric methods such as mass spectrometry (MS) and ion mobility spectrometry (IMS). Among the wide selection of ion optics, temporal ion gates are of particular importance for time-of-flight MS (TOF-MS) and drift-tube IMS. Commonly implemented as electrostatic ion gates, these optics offer a rapid, efficient means to block ion beams and form discrete ion packets for subsequent analysis.

Context-specific eQTLs provide deeper insight into causal genes underlying shared genetic architecture of critically ill COVID-19 and idiopathic pulmonary fibrosis.

Department of Molecular Genetics and Microbiology, Duke University School of Medicine, Durham, NC, USA; University Program in Genetics and Genomics, Duke University, Durham, NC, USA; Division of Infectious Diseases, Department of Medicine, Duke University School of Medicine, Durham, NC, USA. Electronic address:

Most genetic variants identified through genome-wide association studies (GWAS) are suspected to be regulatory in nature, but only a small fraction colocalize with expression quantitative trait loci (eQTLs, variants associated with expression of a gene). Therefore, it is hypothesized but largely untested that integration of disease GWAS with context-specific eQTLs will reveal the underlying genes driving disease associations. We used colocalization and transcriptomic analyses to identify shared genetic variants and likely causal genes associated with critically ill COVID-19 and idiopathic pulmonary fibrosis.
