RCAS is a replication-competent retroviral vector system that allows sustained misexpression of a gene of interest in avian cells. This tool has been used to gain fundamental insights into skeletal development in the chick embryo, and consequently into broader principles of morphogenesis. In this review, we discuss a range of RCAS-based strategies that have been employed to examine gene function during early patterning of the limb bud, later skeletal differentiation, and craniofacial morphogenesis. The potential for the RCAS system as a tool for loss-of-function studies is also discussed.

Quantification of training-induced alterations in body composition via automated machine learning analysis of MRI images in the thigh region: A pilot study in young females.

The maintenance of an appropriate ratio of body fat to muscle mass is essential for the preservation of health and performance, as excessive body fat is associated with an increased risk of various diseases. Accurate body composition assessment requires precise segmentation of structures. In this study we developed a novel automatic machine learning approach for volumetric segmentation and quantitative assessment of MRI volumes and investigated the efficacy of using a machine learning algorithm to assess muscle, subcutaneous adipose tissue (SAT), and bone volume of the thigh before and after a strength training.

It is important to understand the evolving structure-property correlations in these materials during pyrolysis, but the extreme laboratory conditions required to produce C/C composites make it difficult to quantify the properties . This work presents an atomistic modeling methodology to pyrolyze a crosslinked phenolic resin network and track the evolving thermomechanical properties of the skeletal matrix during simulated pyrolysis.

Background: The aging of bone marrow mesenchymal stem cells (BMSCs) impairs bone tissue regeneration, contributing to skeletal disorders. LncRNA NEAT1 is considered as a proliferative inhibitory role during cellular senescence, but the relevant mechanisms remain insufficient. This study aims to elucidate how NEAT1 regulates mitotic proteins during BMSCs aging.

Background: The metabolic score for visceral fat (METS-VF) is a recently identified index for evaluating visceral fat, also referred to as abdominal obesity. The skeletal muscle mass index (SMI) serves as a critical measure for assessing muscle mass and sarcopenia. Both obesity and the reduction of muscle mass can significantly affect human health.

Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death globally, particularly in developing countries in Southeast Asia and sub-Saharan Africa (SSA), where chronic hepatitis B virus (HBV) dominates as a major aetiological factor.
Methods: We conducted a retrospective cohort study to quantify the metastatic profile of HCC in a South African patient population managed at a tertiary centre. Demographic, clinical and treatment data were extracted from an institutional registry.
