Phenotype similarities in automatically grouped T2D patients by variation-based clustering of IL-1β gene expression.

Background: Analyzing longitudinal gene expression data is extremely challenging due to limited prior information, high dimensionality, and heterogeneity. Similar difficulties arise in research of multifactorial diseases such as Type 2 Diabetes. Clustering methods can be applied to automatically group similar observations.

Telomere Length Differently Associated to Obesity and Hyperandrogenism in Women With Polycystic Ovary Syndrome.

Background: Polycystic Ovary Syndrome (PCOS) often present metabolic disorders and hyperandrogenism (HA), facts that may influence the telomere length (TL).

Aims: To compare the absolute TL (aTL) between women with PCOS and control women, and their association with the presence of obesity and HA parameters.

Materials And Methods: The PCOS group included 170 unrelated women outpatients and the control group, 64 unrelated donor women.

Relationship between the IL-1β serum concentration, mRNA levels and rs16944 genotype in the hyperglycemic normalization of T2D patients.

To evaluate Interleukin 1-beta (IL-1β) serum and mononuclear leucocyte mRNA levels, also rs16944 (-511C/T) genotype, in relation to hyperglycemic normalization in Type 2 diabetes (T2D) patients, we recruited 30 individuals recently T2D diagnosed with hyperglycemia studied at basal time and after 6 and 12 months of the normalization treatment. At basal time, the T polymorphic allele of the rs16944 was associated with lower IL-1β mRNA expression (p = 0.006); and higher glucose level was positive correlated to IL-1β protein levels (p = 0.

Inhibition of Osteoblast Function by is Reversed by Dehydroepiandrosterone and Involves ERK1/2 and Estrogen Receptor.

induces an inflammatory response that stimulates the endocrine system resulting in the secretion of cortisol and dehydroepiandrosterone (DHEA). Osteoarticular brucellosis is the most common presentation of the active disease in humans, and we have previously demonstrated that infection inhibits osteoblast function. We aimed to evaluate the role of cortisol and DHEA on osteoblast during infection.

Metabolically healthy obese individuals present similar chronic inflammation level but less insulin-resistance than obese individuals with metabolic syndrome.

The Metabolic Syndrome (MetS) is a cluster of cardiometabolic risk factors, usually accompanied by the presence of insulin resistance (IR) and a systemic subclinical inflammation state. Metabolically healthy obese (MHO) individuals seem to be protected against cardiometabolic complications. The aim of this work was to characterize phenotypically the low-grade inflammation and the IR in MHO individuals in comparison to obese individuals with MetS and control non obese.

Metabolically healthy obese women have longer telomere length than obese women with metabolic syndrome.

Introduction: Obesity is the principal component in the Metabolic Syndrome (MetS) that determines the progression of metabolic complications. Metabolically healthy obese (MHO) individuals seem to be protected against those complications. Telomere length (TL) as a novel marker of cellular aging had a complex relationship to the MetS.

Association between β2-adrenoceptor (ADRB2) haplotypes and insulin resistance in PCOS.

Objective: The aim of this study was to explore β2-adrenoceptor (ADRB2) haplotype associations with phenotypes and quantitative traits related to insulin resistance (IR) and the metabolic syndrome (MS) in a polycystic ovary syndrome (PCOS) population. A secondary purpose was to assess the association between ADRB2 haplotype and PCOS.

Design: Genetic polymorphism analysis.
