Functional Connectivity Favors Aberrant Visual Network c-Fos Expression Accompanied by Cortical Synapse Loss in a Mouse Model of Alzheimer's Disease.

Background: While Alzheimer's disease (AD) has been extensively studied with a focus on cognitive networks, visual network dysfunction has received less attention despite compelling evidence of its significance in AD patients and mouse models. We recently reported c-Fos and synaptic dysregulation in the primary visual cortex of a pre-amyloid plaque AD-model.

Objective: We test whether c-Fos expression and presynaptic density/dynamics differ in cortical and subcortical visual areas in an AD-model.

Physiological Fitness of U.S. Army Aviators Compared to the U.S. General Population.

U.S. Army aviators are required to maintain a level of physiological fitness as part of their qualifying process, which suggests that they are generally physically healthy.

COVID-19 Vaccine Hesitancy Among Pregnant Women.

Background COVID-19 has struck the world severely and caused much damage, losses, and a massive impact on different aspects of life. It is an airborne disease that spreads rapidly among populations and can cause severe illness or death. The rapid nature of its spread led to significant challenges to control it.

Assessing the variation in amount of pressure exerted by haemostatic pressure bandages: a volunteer study.

We assess the range of pressures exerted by haemostatic compression bandages on upper limb arterial injuries. Maintaining a pink hand can act as a safety marker to prevent excessive bandage pressure and avert compression injuries.
