Day and night: diurnal phase influences the response to chronic mild stress.

Chronic mild stress (CMS) protocols are widely used to create animal models of depression. Despite this, the inconsistencies in the reported effects may be indicative of crucial differences in methodology. Here, we considered the time of the diurnal cycle in which stressors are applied as a possible relevant temporal variable underlying the association between stress and behavior.

Energy expenditure regulation via macrophage migration inhibitory factor in obesity and in vitro anti-macrophage migration inhibitory factor effect of Alpinia officinarum Hance extraction.

Objective: To compare the resting energy expenditure in different macrophage migration inhibitory factor (MIF) genotypes and to identify the in vitro effects of Alpinia officinarum Hance extract (AOHE) on MIF expression in obese and nonobese persons.

Methods: In the fasting state, obese and nonobese persons were assessed for the measurement of resting energy expenditure rate (REE) by indirect calorimetry. We compared it with the expected amount ([REE measured by indirect calorimetry / predicted REE according to Harris Benedict equations] x 100).

VDR FokI polymorphism and its potential role in the pathogenesis of gestational diabetes mellitus and its complications.

The aim of the study is evaluating the associations of FokI vitamin D receptor (VDR) gene polymorphisms with gestational diabetes mellitus (GDM), and its relations with postpartum metabolic syndrome. In a cohort study, 303 women referred to outpatient clinic of Shariati Hospital. The VDR FokI genotypes were determined.
