Combined Effects of Spirulina Liquid Extract and Endurance Training on Aerobic Performance and Muscle Metabolism Adaptation in Wistar Rats.

Background: Physical activity, such as running, protects against cardiovascular disease and obesity but can induce oxidative stress. Athletes often consume antioxidants to counteract the overproduction of reactive oxygen and nitrogen species during exercise. , particularly its phycocyanin content, activates the Nrf2 pathway, stimulating antioxidant responses.

Implementation of a "hypoglycemia kit" in a pediatric emergency room: A retrospective study during 2011-2019.

Introduction: Hypoglycemia is a common symptom in pediatrics that can lead to neurological sequelae. The etiologies are mostly benign, but hypoglycemia can be a symptom of severe underlying disease. To streamline the etiological investigations, a "hypoglycemia kit," containing supplies needed to perform specific analyses quickly, was made available in the pediatric emergency department of the Rouen University Hospital in 2011.

Comparison of two ecotypes under nitrogen starvation and resupply reveals distinct lipid accumulation strategies but a common degradation process.

Introduction: is a model species frequently used to study lipid metabolism in diatoms. When exposed to a nutrient limitation or starvation, diatoms are known to accumulate neutral lipids in cytoplasmic lipid droplets (LDs). Those lipids are produced partly de novo and partly from the recycle of plastid membrane lipids.

Microalgae Produce Antioxidant Molecules with Potential Preventive Effects on Mitochondrial Functions and Skeletal Muscular Oxidative Stress.

In recent years, microalgae have become a source of molecules for a healthy life. Their composition of carbohydrates, peptides, lipids, vitamins and carotenoids makes them a promising new source of antioxidant molecules. Skeletal muscle is a tissue that requires constant remodeling via protein turnover, and its regular functioning consumes energy in the form of adenosine triphosphate (ATP), which is produced by mitochondria.

Dopaminergic and prefrontal dynamics co-determine mouse decisions in a spatial gambling task.

The neural mechanisms by which animals initiate goal-directed actions, choose between options, or explore opportunities remain unknown. Here, we develop a spatial gambling task in which mice, to obtain intracranial self-stimulation rewards, self-determine the initiation, direction, vigor, and pace of their actions based on their knowledge of the outcomes. Using electrophysiological recordings, pharmacology, and optogenetics, we identify a sequence of oscillations and firings in the ventral tegmental area (VTA), orbitofrontal cortex (OFC), and prefrontal cortex (PFC) that co-encodes and co-determines self-initiation and choices.
