Objective: To assess the effects of exenatide on body weight and glucose tolerance in nondiabetic obese subjects with normal or impaired glucose tolerance (IGT) or impaired fasting glucose (IFG).
Research Design And Methods: Obese subjects (n = 152; age 46 +/- 12 years, female 82%, weight 108.6 +/- 23.0 kg, BMI 39.6 +/- 7.0 kg/m(2), IGT or IFG 25%) were randomized to receive exenatide (n = 73) or placebo (n = 79), along with lifestyle intervention, for 24 weeks. RESULTS Exenatide-treated subjects lost 5.1 +/- 0.5 kg from baseline versus 1.6 +/- 0.5 kg with placebo (exenatide--placebo, P < 0.001). Placebo-subtracted difference in percent weight reduction was -3.3 +/- 0.5% (P < 0.001). Both groups reduced their daily calorie intake (exenatide, -449 cal; placebo, -387 cal). IGT or IFG normalized at end point in 77 and 56% of exenatide and placebo subjects, respectively.
Conclusions: Exenatide plus lifestyle modification decreased caloric intake and resulted in weight loss in nondiabetic obesity with improved glucose tolerance in subjects with IGT and IFG.

Objective: This study aims to investigate the possible effects of gestational diabetes mellitus (GDM) on fetal heart structure and the relationship of this effect with maternal blood sugar control.
Materials And Methods: In this cross-sectional study, 19 women with GDM at 24-36 weeks of gestation (case group) and 21 healthy pregnant women at the same weeks of gestation (control group) were examined. Fetal heart structure was evaluated by ultrasonography; interventricular septum (IVS) thickness, right and left ventricular sphericity indices, global sphericity index (GSI) and cardio-thoracic ratio were also measured.

Introduction: Consuming hypercaloric diets during pregnancy induces metabolic, immune, and maternal intestinal dysbiosis disorders. These conditions are transferred to the offspring through the placenta and breastfeeding, increasing susceptibility to metabolic diseases. We investigated the effect of GG supplementation on offspring maternally programmed with a hypercaloric diet.

We investigated the effects of exogenous abscisic acid (ABA) on grain filling, starch accumulation, and endogenous hormones in maize (both the heat-tolerant maize variety Zhengdan 958 (ZD958) and the heat-sensitive variety Xianyu 335 (XY335)) under early post-anthesis high temperature stress by simulating high temperature stress for a period of 6 to 12 days post-anthesis in 2022 and 2023. There were three treatments: spraying water at ambient temperature as the control, spraying water at high temperature, and spraying ABA at high temperature. The results showed that early post-anthesis high temperature stress resulted in a significant reduction in grain weight and yield in maize, with XY335 showing a greater reduction than ZD958.

Department of Pediatrics, Division of Pediatric Endocrinology, University of Michigan, Ann Arbor, USA.
Context: Insulin sensitivity and secretion indices can be useful tools in understanding insulin homeostasis in children at risk for diabetes. There have been few studies examining the reproducibility of these measures in pediatrics.
Objective: To determine whether fasting or oral glucose tolerance test (OGTT)-derived insulin measures would be more reproducible and whether there would be differences based on weight, sex, race, and pubertal status.
