Hyperglycemia-Driven Neuroinflammation Compromises BBB Leading to Memory Loss in Both Diabetes Mellitus (DM) Type 1 and Type 2 Mouse Models.

End organ injury in diabetes mellitus (DM) is driven by microvascular compromise (including diabetic retinopathy and nephropathy). Cognitive impairment is a well-known complication of DM types 1 and 2; however, its mechanism(s) is(are) not known. We hypothesized that blood-brain barrier (BBB) compromise plays a key role in cognitive decline in DM.

Protease-activated receptor 4 deficiency offers cardioprotection after acute ischemia reperfusion injury.

Protease-activated receptor (PAR)4 is a low affinity thrombin receptor with less understood function relative to PAR1. PAR4 is involved in platelet activation and hemostasis, but its specific actions on myocyte growth and cardiac function remain unknown. This study examined the role of PAR4 deficiency on cardioprotection after myocardial ischemia-reperfusion (IR) injury in mice.

Hepatoprotective properties of aqueous extract from Pentaphylloides fruticosa during chronic toxic hepatitis.

Hepatoprotective properties of Pentaphylloides fruticosa L. aqueous extract were studied using rat model of chronic toxic hepatitis. The preparation normalized alanine aminotransferase activity and bilirubin concentration in the plasma.
