Epithelial-to-mesenchymal transition and live cell extrusion contribute to measles virus release from human airway epithelia.

Measles virus (MeV) is a highly contagious respiratory virus transmitted via aerosols. To understand how MeV exits the airways of an infected host, we use unpassaged primary cultures of human airway epithelial cells (HAE). MeV typically remains cell-associated in HAE and forms foci of infection, termed infectious centers, by directly spreading cell-to-cell.

Lossless and reference-free compression of FASTQ/A files using GeneSqueeze.

As sequencing becomes more accessible, there is an acute need for novel compression methods to efficiently store sequencing files. Omics analytics can leverage sequencing technologies to enhance biomedical research and individualize patient care, but sequencing files demand immense storage capabilities, particularly when sequencing is utilized for longitudinal studies. Addressing the storage challenges posed by these technologies is crucial for omics analytics to achieve their full potential.

Background: Highly pathogenic avian influenza A(H5N1) viruses have caused widespread infections in dairy cows and poultry in the United States, with sporadic human cases. We describe characteristics of human A(H5N1) cases identified from March through October 2024 in the United States.

Methods: We analyzed data from persons with laboratory-confirmed A(H5N1) virus infection using a standardized case-report form linked to laboratory results from the Centers for Disease Control and Prevention influenza A/H5 subtyping kit.

Determinants of physical activity adoption and maintenance in older adults: A dual process approach.

Background: Dual process models represent a useful framework for explaining physical activity (PA) in that behavior is explained by reflective (i.e., conscious, effortful) and automatic (i.

Patient-specific adaptive planning margin for whole bladder radiation therapy.

Background: Whole bladder irradiation is an organ preservation treatment approach for muscle-invasive bladder cancer (MIBC). Conventional planning margins, typically 15-20 mm, increase normal tissue toxicity and limit possible dose escalation.

Purpose: The study aimed to develop a patient-specific adaptive margin recipe for whole bladder irradiation to minimize the planning target volume (PTV) while preserving adequate dose coverage.

Posted in Error: Did the CDC's Retraction of Aerosol Guidance Undercut Its Public Reputation?

While there is ample research on the influence of retracted scientific publications on author reputation, less is known about how a health organization's retraction of scientific guidance can impact public perceptions of the organization. This study centers on the aerosol guidance retraction of the Centers for Disease Control and Prevention (CDC) in 2020. X/Twitter social media data were collected via ForSight from September 15 to October 8, 2020, with a machine learning algorithm specifically developed and used to detect sentiment toward the CDC.

Quality Controls: The Role of Self-Corrective Science in Explorations of Primate Memory Systems.

In 1978, Mort Mishkin published a landmark paper describing a monkey model of H.M.'s dense, global amnesia.

The Rho effector ARHGAP18 coordinates a Hippo pathway feedback loop through YAP and Merlin to regulate the cytoskeleton and epithelial cell polarity.

The organization of the cell's cytoskeletal filaments is coordinated through a complex symphony of signaling cascades originating from internal and external cues. Two major actin regulatory pathways are signal transduction through Rho family GTPases and growth and proliferation signaling through the Hippo pathway. These two pathways act to define the actin cytoskeleton, controlling foundational cellular attributes such as morphology and polarity.

Omega-3 and Risk of atrial fibrillation: Vagally-mediated double-edged sword.

Objective: Studies regarding effects of omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), on risk of atrial fibrillation (AF) have reported discordant results. The aim of this review is to clarify effects of marine omega-3 intake on risk of AF.

Patients And Methods: A PubMed search was performed using terms: atrial fibrillation, omega-3, EPA, DHA, vagal tone.

Different facets of age perception in people with developmental prosopagnosia and "super-recognisers".

The interplay between facial age and facial identity is evident from several scenarios experienced in daily life, such as when recognising a face several decades after the last exposure. However, the link between age and identity processing, and how age perception abilities might diverge in individuals with different face processing abilities, has scarcely been considered. Furthermore, the approach used to test age perception ability may also influence outcome, but the effect of different paradigms on performance is not yet known.

Does the health of local populations modify occupational differences in employment rates of older workers? Findings from the ONS Longitudinal Study 2001-2011.

Poor health is a key reason for early exit from the labour market. Few studies have explored how the health of local populations is related to occupational differences in employment outcomes among older people. Our study used data for England and Wales from the ONS Longitudinal Study linked with 2001 Census measures of the health of the older working age population at local authority level.

Altered Gut Microbiota Patterns in Young Children with Recent Maltreatment Exposure.

Background: The brain and the intestinal microbiota are highly interconnected and especially vulnerable to disruptions in early life. Emerging evidence indicates that psychosocial adversity detrimentally impacts the intestinal microbiota, affecting both physical and mental health. This study aims to investigate the gut microbiome in young children in the immediate aftermath of maltreatment exposure.

Evaluation of a non-nucleoside inhibitor of the RSV RNA-dependent RNA polymerase in translatable animals models.

Respiratory Syncytial Virus (RSV) causes severe respiratory infections and concomitant disease resulting in significant morbidity and mortality in infants, elderly, and immunocompromised adults. Vaccines, monoclonal antibodies, and small-molecule antivirals are now either available or in development to prevent and treat RSV infections. Although rodent and non-rodent preclinical animal models have been used to evaluate these emerging agents, there is still a need to improve our understanding of the pharmacokinetic (PK)-pharmacodynamic (PD) relationships within and between animal models to enable better design of human challenge studies and clinical trials.

Divergent gene expression patterns in alcohol and opioid use disorders lead to consistent alterations in functional networks within the dorsolateral prefrontal cortex.

Substance Use Disorders (SUDs) manifest as persistent drug-seeking behavior despite adverse consequences, with Alcohol Use Disorder (AUD) and Opioid Use Disorder (OUD) representing prevalent forms associated with significant mortality rates and economic burdens. The co-occurrence of AUD and OUD is common, necessitating a deeper comprehension of their intricate interactions. While the causal link between these disorders remains elusive, shared genetic factors are hypothesized.

Pulse wave velocity as a tool for cardiometabolic risk stratification in individuals with hypertensive disorders of pregnancy and increased BMI.

Objective: Obesity is one of the most prevalent risk factors for hypertensive disorders in pregnancy (HDP); however, the role of pre-pregnancy cardiometabolic health in the development of these conditions is not well understood. Carotid-femoral pulse wave velocity (PWV) is an established measure of arterial stiffness and cardiovascular health and is validated in pregnancy. Our objective was to examine the obesity-related changes in PWV in pregnant individuals with and without HDP.
