Abstract: Phospholipase A2 (PLA2) is a crucial element for normal neuro-physiological function.study aims to investigate the genetic association between the polymorphism of cytosolic phospholipase A2(cPLA2) family genes and schizophrenia among Han Chinese in the northern part of China.The genotypic frequency of cPLA2 gene did not deviate from Hardy-Weinberg equilibrium either in caseOur data suggest that many loci in the cPLA2 family genes may be associated with schizophrenia.

Abstract:

Obesity increases the risk for type 2 diabetes through induction of insulin resistance.Treatment of type 2 diabetes has been limited by little translational knowledge of insulin resistanceHowever, none of those concepts or views has led to an effective therapy for type 2 diabetes.The energy surplus signal is mediated by ATP and sensed by adenosine monophosphate-activated protein
