Screen Time and Hours of Sleep Influence the Estimate Risk of Diabetes Mellitus and Metabolic Syndrome in Healthy Young Males.

Screen time (ST) has shown negative effects on physical and mental health, with an increase in the prevalence of overweight, metabolic syndrome (MetS), and obesity. The time spent in front of the screens was also associated with higher odds of selecting indicators of cardiometabolic disease in adulthood. In view of this, the aim of this study was to identify the risk of MetS and type 2 diabetes mellitus (T2DM) in healthy young males and relate it to ST and sleep time.

Advances in separation methods for the use of platelet-rich fibrin in tissue repair: an integrative review.

Plasma preparations originating from the centrifugation of blood samples, such as platelet-rich plasma (PRP) and platelet-rich fibrin (PRF), have proven useful for the treatment of gingival recession due to their rich concentration of cells and cytokines fundamental in the mechanisms of both soft tissue and hard tissue repair. Depending on the preparation method used to generate PRP and PRF, different concentrations of plasma elements and physicochemical characteristics can be obtained. This study sought to perform an integrative literature review to compile the available data on different protocols for generating plasma preparations and their indications, benefits, and results.

Variants in HSD11B1 gene modulate susceptibility to diabetes kidney disease and to insulin resistance in type 1 diabetes.

Background And Aim: 11β-Hydroxysteroid dehydrogenase 1 has been implicated in insulin resistance (IR) in the setting of metabolic disorders, and single nucleotide polymorphisms (SNPs) in its encoding gene (HSD11B1) have been associated with type 2 diabetes and metabolic syndrome. In type 1 diabetes (T1D), IR has been related to the development of chronic complications. We investigated the association of HSD11B1 SNPs with microvascular complications and with IR in a Brazilian cohort of T1D individuals.

Allelic variations in genes belonging to glutathione system increase proliferative retinopathy risk in type 1 diabetes individuals.

Aims: Given the participation of oxidative stress in the pathogenesis of diabetic complications, we evaluated, in type 1 diabetes (T1D) individuals, the association between diabetic retinopathy (DR) and functional single nucleotide polymorphisms (SNPs) in regulatory regions of two genes belonging to the antioxidant glutathione (GSH) system: rs17883901 in GCLC and rs713041 in GPX4.

Methods: A cross-sectional case-control study included 288 individuals (61% women, 34[±11] years old, diabetes duration of 22[±9] years, mean [±SD]) sorted according to DR stages: absence of DR (ADR), non-proliferative DR (NPDR) and proliferative DR (PDR). SNPs were genotyped by real-time PCR using fluorescent labelled probes.

Glutathione peroxidase 4 functional variant rs713041 modulates the risk for cardiovascular autonomic neuropathy in individuals with type 1 diabetes.

Cardiac autonomic neuropathy is a neglected diabetic chronic complication for which genetic predictors are rarely reported. Oxidative stress is implicated in the pathogenesis of microvascular complications, and glutathione peroxidase 4 is involved in the detoxification of peroxides and of reactive oxygen species. Thus, the association of a functional variant in the gene encoding glutathione peroxidase 4 (rs713041) with this diabetic complication was investigated in 341 individuals with type 1 diabetes evaluated for cardiac autonomic neuropathy status (61.

Beta-2-microglobulin (B2M) expression in the urinary sediment correlates with clinical markers of kidney disease in patients with type 1 diabetes.

Purpose: After observing variation in the expression of the housekeeping gene B2M in cells of the urinary sediment during a study of candidate genes potentially involved in diabetic kidney disease (DKD), we hypothesized that B2M mRNA expression in the urinary sediment could reflect the presence of DKD.

Effect of thyroid hormone on uncoupling protein-3 mRNA expression in rat heart and skeletal muscle.

Thyroid hormones (triiodothyronine [T3] and thyroxine [T4]) stimulate UCP-3 expression in skeletal muscle. We examined whether thyroid hormone-induced changes in uncoupling protein (UCP)-3 mRNA expression are related to directs effects of T3 or reflect secondary effects of the hormone through stimulation of renin-angiotensin or beta-adrenergic systems. Hyperthyroidism was produced by three injections of 100 microg T3/100 g body weight on alternate days with or without concomitant treatment with either captopril (an angiotensin-converting enzyme [ACE] inhibitor), propranolol (a beta-blocker) or clenbuterol (a beta2-agonist).

Thyroid hormone regulation of cardiac bioenergetics: role of intracellular creatine.

The effect of thyroid hormone (T(3)) on the content of myocardial creatine (Cr), Cr phosphate (CrP), and high-energy adenine nucleotides and on cardiac function was examined. In the hearts of control and T(3)-treated rats perfused in vitro, while "low" and "high" contractile work was performed, T(3) treatment resulted in a approximately 50% reduction in CrP, Cr, total Cr content (Cr + CrP), and in the CrP-to-Cr ratio. In addition, there was a slight fall in myocardial content of ATP and a large rise in calculated free ADP (fADP), resulting in a significant decrease in the ATP-to-fADP ratio in the hearts of hyperthyroid compared with euthyroid rats.
