Pharmacogenetic and clinical predictors of response to clopidogrel plus aspirin after acute coronary syndrome in Egyptians.

Objectives: Dual antiplatelet therapy (DAPT) with aspirin and clopidogrel reduces the risk for recurrent cardiovascular events after acute coronary syndrome (ACS). However, there is significant variation in response to DAPT that may be influenced by both genetic and nongenetic factors. This study aimed to assess the effect of genetic polymorphisms in PON-1, PEAR-1, P2Y12, CES1, and CYP2C19, along with clinical, demographic, and social factors, on variation in response to DAPT in Egyptians.

Once versus individualized multiple daily dosing of aminoglycosides in critically ill patients.

Background And Objective: The purpose of this study was to evaluate the once daily dosing (ODD) program in critically ill Egyptian patients compared to individualized multiple daily dosing (MDD) in terms of clinical and bacteriological efficacy. In addition, the incidence of nephrotoxicity associated with both regimens in this specific group of patients was assessed.

Methods: Fifty-two patients with suspected or confirmed bacterial infections admitted to the Critical Care Medicine Department, Kasr El-Aini-Cairo University Hospitals comprised the study population.

Proapoptotic and prepulse inhibition (PPI) disrupting effects of Hypericum perforatum in rats.

Ethnopharmacological Relevance: St. John's wort extract is commonly used as a wound healing, anti-inflammatory, anxiolytic, diuretic, antibiotic, antiviral and cancer chemoprotective agent. It also has nootropic and/or antiamnestic effects.

Involvement of serotoninergic 5-HT1A/2A, alpha-adrenergic and dopaminergic D1 receptors in St. John's wort-induced prepulse inhibition deficit: a possible role of hyperforin.

Prepulse inhibition (PPI) of acoustic startle response is a valuable paradigm for sensorimotor gating processes. Previous research showed that acute administration of St. John's wort extract (500 mg/kg, p.
