Traumatic Tension Pneumothorax: A Tale of Two Pathologies.

Pneumothorax resulting from injury is a common phenomenon in both civilian and military trauma. A pneumothorax or simple pneumothorax is defined as air in the pleural space. A tension pneumothorax can evolve from a simple pneumothorax if there is a continued air leak from the lung without mechanism for egress.

25-Hydroxycholecalciferol Improves Cardiac Metabolic Adaption, Mitochondrial Biogenetics, and Redox Status to Ameliorate Pathological Remodeling and Functional Failure in Obese Chickens.

Broiler breeder hens allowed ad libitum (Ad) feed intake developed obesity and cardiac pathogenesis and thereby were susceptible to sudden death. A supplement of 69 µg 25-hydroxycholecalciferol (25-OH-D3)/kg feed rescued the livability of feed-restricted (R) and Ad-hens (mortality; 6.7% vs.

Cellular and molecular alterations to muscles and neuromuscular synapses in a mouse model of MEGF10-related myopathy.

Loss-of-function mutations in MEGF10 lead to a rare and understudied neuromuscular disorder known as MEGF10-related myopathy. There are no treatments for the progressive respiratory distress, motor impairment, and structural abnormalities in muscles caused by the loss of MEGF10 function. In this study, we deployed cellular and molecular assays to obtain additional insights about MEGF10-related myopathy in juvenile, young adult, and middle-aged Megf10 knockout (KO) mice.

Origin, identity, and function of terminal Schwann cells.

The highly specialized nonmyelinating glial cells present at somatic peripheral nerve endings, known collectively as terminal Schwann cells (TSCs), play critical roles in the development, function and repair of their motor and sensory axon terminals and innervating tissue. Over the past decades, research efforts across various vertebrate species have revealed that while TSCs are a diverse group of cells, they share a number of features among them. In this review, we summarize the state-of-knowledge about each TSC type and explore the opportunities that TSCs provide to treat conditions that afflict peripheral axon terminals.

A Scoping Review of the Biological, Socioeconomic and Environmental Determinants of Overweight and Obesity Among Middle Eastern and Northern African Nationalities.

Objectives: Globally, and particularly in the Middle East and North Africa (MENA) region, overweight and obesity have become serious public health concerns. This scoping review aimed to identify and summarise the available data on the determinants of overweight and obesity among MENA nationalities.

Methods: An extensive search of electronic databases, including Google Scholar, PubMed and ProQuest, for articles published from 2007 until 2022 was conducted.
