the purpose of the present study was to investigate the effect of endurance (et), resistance (rt) and concurrent training (ct) on plasma levels of visfatin, insulin, glucose and insulin resistance of non-athlete men with obesity. it was a semi-experimental study. thirty six men [age: 21.48 (0.25), and bf%: 27.39 (0.52)], voluntarily participated in this study after public announcement in univer...

OBJECTIVE Smoking is associated with reduced bone density and calcium absorption, and reduced serum levels of vitamin D. A compensatory increase in serum parathyroid hormone (PTH) would therefore be expected as a result of an altered calcium balance. However, reports on PTH levels in smokers are conflicting. As serum PTH levels give important information on the calcium balance, the PTH levels i...

Intermittent application of parathyroid hormone (PTH) has well established anabolic effects on bone mass in rodents and humans. Although transcriptional mechanisms responsible for these effects are not fully understood, it is recognized that transcriptional factor cAMP response element binding protein (CREB) mediates PTH signaling in osteoblasts, and that there is a communication between the PT...

Objective: To investigate the effects of serum calcium and phosphorus levels on static dynamic pupillometry measurements in patients with postoperative hypoparathyroidism. Material Methods: Pupillometry were undertaken by using an automatic to detect high photopic, low mesopic, scotopic pupil diameters amplitude, latency, duration velocity contraction dilatation. Duration hypoparathyroidism par...

BACKGROUND Acute administration of parathyroid hormone (PTH) causes vasodilation and blood pressure decrease in experimental animals. This effect contrasts with the putative role of secondary hyperparathyroidism in the pathogenesis of hypertension of patients with renal failure. Uraemia is characterized by insulin resistance and hyperinsulinaemia. We therefore investigated whether subacute admi...

OBJECTIVE Primary hyperparathyroidism is usually characterized by a monoclonal parathyroid tumor secreting excess parathyroid hormone (PTH). The main regulator of PTH secretion is calcium and the calcium-PTH set point is shifted in parathyroid tumor cells. We sought to investigate the relationship between tumor PTH and PTH mRNA expression and clinical presentation as well as the regulatory fact...

Experimental and clinical data implicate calcium and parathyroid hormone (PTH) in the development of prostate cancer. However, epidemiologic data on the role of these variables in prostate health are sparse. We examined the relationship between serum levels of calcium, PTH, and prostate-specific antigen (PSA), an established marker of prostate growth, in a large, population-based study using mu...
