Jugular Venous Reflux

open access: yesJournal of Medical Ultrasound, 2008
Cerebral venous outflow impairment is known to produce cerebral dysfunction in many clinical and animal studies. However, knowledge and understanding of the cerebral venous system is far less than that of the arterial system. The internal jugular vein, which is easily observed by color-coded Doppler sonography, is one of the main tracts for cerebral ...

Sex‐ and Time‐Resolved Physiological and Gut Ecosystem Responses to a Food‐Grade Microbiome‐Targeted Intervention in Collegiate Endurance Athletes

open access: yesAdvanced Science, EarlyView.
In collegiate endurance athletes, a 6‐week randomized CPYE intervention yielded time‐ and sex‐dependent shifts in field‐based cardiorespiratory, metabolic, and redox indices, accompanied by changes in gut multi‐omics profiles. An exploratory extension during intensified training generates hypotheses warranting future validation.

Hederagenin Attenuates Morphine Addiction via GABAA1‐Mediated Modulation of Ca2+–CaMK–CREB Signaling in Ventral Tegmental Dopaminergic Neurons

open access: yesAdvanced Science, EarlyView.
Hederagenin is identified as a GABAA1‐targeting natural compound that suppresses morphine‐associated reward by restraining Ca2+–CaMK–cAMP–CREB signaling in ventral tegmental dopaminergic neurons. RVG29‐modified liposomal delivery further enhances brain accumulation and behavioral efficacy, providing a mechanistically defined strategy for natural ...
