New insights into the impact of bed rest on lumbopelvic muscles: a computer-vision model approach to measure fat fraction changes.

Space agencies plan crewed missions to the Moon and Mars. However, microgravity-induced lumbopelvic deconditioning, characterized by an increased fat fraction (FF) due to reduced physical activity, poses a significant challenge to spine health. This study investigates the spatial distribution of FF in the lumbopelvic muscles to identify the most affected regions by deconditioning, utilizing a computer-vision model and a tile-based approach to assess FF changes.

Longitudinal changes in lifestyle behaviours and cardiovascular health during the transition to fatherhood: the Dad Bod observational cohort study protocol.

Introduction: Despite the importance of the transition to fatherhood as a critical life stage among young adult men, much remains unknown about the factors predictive of ideal cardiovascular health (CVH) and how CVH is impacted as young men face new roles and responsibilities associated with fatherhood.

Methods And Analysis: To address this gap, the Dad Bod Study is a prospective, longitudinal and observational study designed to examine how fatherhood affects young men's CVH. A total of 125, first-time prospective fathers (men, 19-39 years) will be enrolled and followed over 1.

Development of a Culinary Medicine Curriculum to Support Nutrition Knowledge for Gastroenterology Fellows and Faculty.

Gastroenterologists encounter many nutrition-related disorders in their practice, yet the nutritional needs of patients with chronic gastrointestinal (GI) and liver disease are largely unaddressed by treating physicians, due to suboptimal nutrition education. To address this gap, we developed and piloted a culinary medicine course for a GI fellowship training program. The objective of this study is to describe the development, implementation, and acceptability of the course.

The autoimmune rheumatological presentation of Common Variable Immunodeficiency Disorders with an overview of genetic testing.

Primary immunodeficiency Disorders (PIDS) are rare, mostly monogenetic conditions which can present to a number of specialties. Although infections predominate in most PIDs, some individuals can manifest autoimmune or inflammatory sequelae as their initial clinical presentation. Identifying patients with PIDs can be challenging, as some can present later in life.

Simulated inventory and distribution of Cs released from multiple sources in the global ocean.

Radioactive cesium (Cs) is distributed in the world's oceans as a result of global fallout from atmospheric nuclear weapons tests, releases from fuel reprocessing plants, and inputs from nuclear power plant accident. In order to detect future radionuclide contamination, it is necessary to establish a baseline global distribution of radionuclides such as Cs and to understand the ocean transport processes that lead to that distribution. In order to aid in the interpretation of the observed database, we have conducted a suite of simulations of the distribution of Cs using a global ocean general circulation model (OGCM).

The Spatial Patterns and Determinants of Cerebrospinal Fluid Circulation in the Human Brain.

The circulation of cerebrospinal fluid (CSF) is essential for maintaining brain homeostasis and clearance, and impairments in its flow can lead to various brain disorders. Recent studies have shown that CSF circulation can be interrogated using low b-value diffusion magnetic resonance imaging ( dMRI). Nevertheless, the spatial organization of intracranial CSF flow dynamics remains largely elusive.

Kinesin and myosin motors compete to drive rich multiphase dynamics in programmable cytoskeletal composites.

The cellular cytoskeleton relies on diverse populations of motors, filaments, and binding proteins acting in concert to enable nonequilibrium processes ranging from mitosis to chemotaxis. The cytoskeleton's versatile reconfigurability, programmed by interactions between its constituents, makes it a foundational active matter platform. However, current active matter endeavors are limited largely to single force-generating components acting on a single substrate-far from the composite cytoskeleton in cells.

Unveiling invasive insect threats to plant biodiversity: Leveraging eDNA metabarcoding and saturated salt trap solutions for biosurveillance.

The negative global impacts of invasive alien species (IAS) on biodiversity are second only to habitat loss. eDNA metabarcoding allows for a faster and more comprehensive evaluation of community species composition, with a higher taxonomic resolution and less taxonomic expertise required than traditional morphological-based biosurveillance. These advantages have positioned eDNA metabarcoding as the standard method for molecular-based detection of invasive alien species, where fast and accurate detectability allows prompt responses to mitigate their adverse effects.

SNIP1 and PRC2 coordinate cell fates of neural progenitors during brain development.

Stem cell survival versus death is a developmentally programmed process essential for morphogenesis, sizing, and quality control of genome integrity and cell fates. Cell death is pervasive during development, but its programming is little known. Here, we report that Smad nuclear interacting protein 1 (SNIP1) promotes neural progenitor cell survival and neurogenesis and is, therefore, integral to brain development.

Prevention of early-onset cardiomyopathy in exon 52-54 deletion mice by CRISPR-Cas9-mediated exon skipping.

Duchenne muscular dystrophy (DMD) is a disease with a life-threatening trajectory resulting from mutations in the dystrophin gene, leading to degeneration of skeletal muscle and fibrosis of cardiac muscle. The overwhelming majority of mutations are multiexonic deletions. We previously established a dystrophic mouse model with deletion of exons 52-54 in that develops an early-onset cardiac phenotype similar to DMD patients.

Oxford brain health clinic: protocol and research database.

Introduction: Despite major advances in the field of neuroscience over the last three decades, the quality of assessments available to patients with memory problems in later life has barely changed. At the same time, a large proportion of dementia biomarker research is conducted in selected research samples that often poorly reflect the demographics of the population of patients who present to memory clinics. The Oxford Brain Health Clinic (BHC) is a newly developed clinical assessment service with embedded research in which all patients are offered high-quality clinical and research assessments, including MRI, as standard.
