[Effects of hydroxyl acetylated curcumin induced sonodynamic therapy on viability, apoptosis and necrosis of THP-1 macrophages].

Objective: We aim to investigate the sonodynamic effect induced by hydroxyl acetylated curcumin (HAC) on THP-1 macrophages.

Methods: THP-1 derived macrophages (1 x 10(5) per milliliter) were cultured with HAC at a concentration of 5 µg/mL for 4 h and then exposed to pulse ultrasound treatment (0.5 W/cm2) for 5 min.

Anti-apoptotic action of hydrogen sulfide is associated with early JNK inhibition.

The mechanism of action of Hydrogen sulfide (H(2)S) as a novel endogenous gaseous messenger and potential cardioprotectant is not fully understood. We therefore investigated the prevention of cardiomyocyte apoptosis by exogenous H(2)S and the signaling pathways leading to cardioprotection. Using a simulated ischemia-reperfusion (I/Re) model with primary cultured rat neonatal cardiomyocytes, I/Re induced a rapid, time-dependent phosphorylation of c-Jun N-terminal kinase (JNK), with significant elevation at 0.

Effects of pravastatin on the function of dendritic cells in patients with coronary heart disease.

The aim of the study was to investigate the functional profile of dendritic cells in patients with coronary heart disease and the effects of pravastatin on this. Forty-eight patients with coronary heart disease were divided into three groups: 16 treated with pravastatin 10 mg/day, 16 treated with pravastatin 20 mg/day and 16 not treated with pravastatin. Dendritic cells from 48 patients with coronary heart disease (before and 4 weeks after the treatment) and 16 healthy individuals were derived from peripheral blood.
