Mild sleep restriction increases endothelial oxidative stress in female persons.

Sleep restriction is associated with increased cardiovascular risk, which is more pronounced in female than male persons. We reported recently first causal evidence that mild, prolonged sleep restriction mimicking "real-life" conditions impairs endothelial function, a key step in the development and progression of cardiovascular disease, in healthy female persons. However, the underlying mechanisms are unclear.

Melittin - A bee venom component - Enhances muscle regeneration factors expression in a mouse model of skeletal muscle contusion.

Melittin is a major peptide component of sweet bee venom that possesses anti-allergic, anti-inflammatory, anti-arthritis, anti-cancer, and neuroprotective properties. However, the therapeutic effects of melittin on muscle injury have not been elucidated. We investigated the therapeutic effects of melittin on muscle injury in a mouse model of muscle contusion.

Pachymic Acid Enhances Pentobarbital-Induced Sleeping Behaviors via GABAA-ergic Systems in Mice.

This study was investigated to know whether pachymic acid (PA), one of the predominant triterpenoids in Poria cocos (Hoelen) has the sedative-hypnotic effects, and underlying mechanisms are mediated via γ-aminobutyric acid (GABA)-ergic systems. Oral administration of PA markedly suppressed locomotion activity in mice. This compound also prolonged sleeping time, and reduced sleep latency showing synergic effects with muscimol (0.

Cordycepin Increases Nonrapid Eye Movement Sleep via Adenosine Receptors in Rats.

Cordycepin (3'-deoxyadenosine) is a naturally occurring adenosine analogue and one of the bioactive constituents isolated from Cordyceps militaris/Cordyceps sinensis, species of the fungal genus Cordyceps. It has traditionally been a prized Chinese folk medicine for the human well-being. Because of similarity of chemical structure of adenosine, cordycepin has been focused on the diverse effects of the central nervous systems (CNSs), like sleep regulation.
