Objective: To investigate the association of the gonadal axis with pro- and anti- oxidation, in relation to obesity and pubertal status in boys, before and after a stimulatory exercise bout.Design: Cross-sectional human experimental study.Methods: Ninty-two healthy normal-weight and obese pre- and early- pubertal boys, participated in this study. All subjects underwent a baseline blood sampling followed by an aerobic exercise bout ...

Background: CD59 is a complement regulatory protein which inhibits membrane attack complex protecting self-cells from complement-mediated damage. Recent evidence suggests CD59 may suppress T cell activation via a complement-independent mechanism. Other than an immune regulator, CD59 is shown to regulate glucose stimulated insulin secretion. Herein we report a patient with inherited CD59 deficiency who developed type 1 diabetes.Case: 11 year-old girl was ...

Background: Thrombocyte volume parameters such as mean thrombocyte volume (MPV) and PDW (thrombocyte distribution volume) are parameters used in evaluation of thrombocyte size which have hemostatic importance. The increased thrombocyte volume is a marker of thrombocyte activation. The thrombocyte activity is important in pathophysiology of diseases with a tendency of thrombosis and inflammation. In adult studies it has been reported that MPV increases in thrombotic diseases su...

Background: The age limit for precocious puberty (PP) in girls is a topic that continues to be debated, and there is a new trend that supports the idea that the beginning of breast development in girls between ages 6 and 8 should not be accepted as true PP and it is necessary to label this clinical condition as accelerated puberty or early normal puberty.Objective and hypotheses: The aim of the current study is to determine the diagnostic criteria for gi...

Background: Obesity is considered to be a chronic inflammatory state in which the dysfunction of adipose tissue plays a central role. Adipose tissue is known to express and secrete a variety of products known as ‘adipokines’ including leptin, adiponectin, resistin, and visfatin, as well as cytokines and chemokines such as tumor necrosis factor-α (TNF-α), interleukin-6, and monocyte chemoattractant protein-1.Objective and hypotheses: T...

Background: Endocrine disruptors cause harmful effects to human body through various exposure routes. These chemicals mainly appear to interfere with the endocrine or hormone systems. Bisphenol A (BPA) is known as an endocrine disruptor with an estrogenic effect and it is supposed that it may have a role on development of precocious puberty (PP). Kisspeptin, a hypothalamic peptide, is a neuromodulator of GnRH and it has a big role on regulation of the onset of puberty.<p c...

Introduction: Human breast milk (HBM) contains various components with critical roles in supporting early human growth and development. HBM is highly enriched in miRNAs, short, non-coding RNAs of 18 to 25 nucleotides in length, involved in the development, differentiation, proliferation, metabolism, and death of cells and tissues. miRNAs have been linked to growth control, apoptosis, epigenetic modifications, developmental programming, stem cell differentiatio...

Background: Type 1 diabetes is an autoimmune disease initiated by the invasion of pancreatic islets by immune cells that selectively kill the β cells. The loss of beta cells in Type I diabetes ultimately leads to insulin dependence and major complications that are difficult to manage by insulin injections. Regulation of immune response is a key strategy to control the autoimmunity in diabetic patients. Mesenchymal stem cells have been shown to have an app...

Introduction: Obesity and related metabolic diseases occur as a chronic imbalance between energy intake and energy expenditure. Due to its high metabolic activity, brown adipose tissue (BAT) has become a promising target for the development of new treatment concepts for metabolic disease. Having a high concentration of mitochondria, BAT is necessary to control the entire energy metabolism of the body. BAT consumes significant amounts of glucose and fatty acids...

Introduction: Glucocorticoid-induced osteoporosis is the most frequent cause of secondary osteoporosis. Glucocorticoids are known to diminish β-catenin activity via Wnt pathway signaling, leading to osteoporosis and osteonecrosis. Bone homeostasis depends on the regulation of β-catenin in osteoblasts. Disruption of bone homeostasis, oxidative stress and mitochondrial dysfunction are major causes of glucocorticoid-induced osteoporosis; therefore, alle...
