Association of Leptin and Leptin receptor Gene polymorphisms with Insulin resistance in pregnant women: A cross-sectional study.

Leptin is an adipokine hormone that regulates insulin sensitivity and lipid profile, which may contribute to complications like gestational diabetes.The goal of the study was to examine if there was a link between the leptin (LEP)/leptin receptor (LEPR) gene polymorphism and insulin resistance in pregnant women, and to determine the extent to which the leptin gene polymorphism could cause insulin resistance..

Association of paraoxonase 1 activity and insulin resistance models in type 2 diabetes mellitus: Cross-sectional study.

Background: Diabetes mellitus is a metabolic disorder characterized by hyperglycemia due to defects in insulin secretion, insulin action, or both. Chronic hyperglycemia induces reactive oxygen species and increases oxidative stress. Human serum paraoxonase-1 (PON-1) is an enzyme synthesized in the liver, and it is an antioxidant enzyme with a beneficial role in fighting oxidative stress.

Association of UGT1A6 gene polymorphism with clinical outcome in pediatric epileptic patients on sodium valproate monotherapy.

Pediatric epilepsy comprises chronic neurological disorders characterized by recurrent seizures. Sodium valproate is one of the common antiseizure medications used for treatment. Glucuronide conjugation is the major metabolic pathway of sodium valproate, carried out by the enzyme uridine 5'-diphosphate (UDP) glucuronosyl transferase (UGT) whose gene polymorphisms may alter the clinical outcome.

Association of insulin resistance and leptin receptor gene polymorphism in type 2 diabetes mellitus.

Background: Type 2 diabetes mellitus (T2DM) is a chronic disease that is characterized by impaired glucose metabolism and insulin resistance. The objectives of the study were to evaluate the pattern of leptin receptor gene polymorphism Gln223Arg in T2DM and to identify its association with the serum leptin and insulin levels as well as with insulin resistance in diabetes.

Methods: In this cross-sectional study, genotyping of leptin receptor was done for Gln223Arg alleles by PCR-restriction fragment length polymorphism in 39 patients with type 2 diabetes.
