Background: We characterized and identified the genetic and antigenic variations of circulating rotavirus strains in comparison to used rotavirus vaccines. Methods: Rotavirus-positive samples (n = 231) were collected and ...
The Metabolic Switch of Physical Activity in Non-Obese Insulin Resistant Individuals.
(
MDPI
, 2023 , Article)
Healthy non-obese insulin resistant (IR) individuals are at higher risk of metabolic syndrome. The metabolic signature of the increased risk was previously determined. Physical activity can lower the risk of insulin ...
