The current issue of CEJU brings a somewhat ambiguous paper entitled “Vitamin D and urological cancers” describing (possible) role of the vit. D in the etiology of urological cancers [1]. Indeed, last years brought numerous publications presenting that 1,25-dihydroxyvitamin D3 may alter human susceptibility to different diseases (even improve fitness) and its capability to cure or, at least, to...

Background 25-hydroxy vitamin D [25(OH) VitD] deficiency is a highly prevalent condition, present in approximately 30% to 50% of the general population. A growing body of data suggests that low 25(OH) VitD levels may adversely affect cardiovascular health. The present study aimed to measure the serum levels of 25(OH) Vit D in Congenital heart disease (CHD) children compared to healthy children....

Enhanced formation of superoxide radicals has been proposed to play a major role in the development of nitrate tolerance in humans. We tested the effects of vitamin C (Vit-C) supplementation on glyceroltrinitrate (GTN)-induced hemodynamic effects during 3-d nonintermittent transdermal administration of GTN (0.4 mg/h) in nine healthy subjects. Tolerance development was monitored by changes in ar...

Sunlight is regarded among greatest gifts that are presented in abundance to the human beings from the God. Sunlight is also a rich source of Vitamin D (Vit D) that prevents us from numerous ailments such as autoimmune disorders, various types of cancer, and the above all cardiovascular diseases (CVD). Evident from recent research that Vit D deficiency may be the cause for hypertension, cardiac...

BACKGROUND Children with renal diseases who are treated with glucocorticoids are at increased risk of developing osteoporosis and fractures. However, there is no common strategy for prevention of corticosteroid-induced osteoporosis. The present systematic review was performed to determine whether prevention of bone loss by calcium (Ca), vitamin D (vit D) and/or bisphosphonates is justified, saf...

All trans-retinoic acid (RA) enhances alveolarization in neonates and reinitiates alveolarization in emphysematous adult rat lungs, suggesting that RA may stimulate cell proliferation by upregulating growth factor ligand and/or receptor expression either indirectly or directly by acting on RA-responsive genes encoding growth factors. We report that RA and 1,25-dihydroxyvitamin D(3) (Vit D), alo...

Protein restriction and hypercalcemia result in a urinary concentrating defect in rats and humans. Previous tubular perfusion studies show that there is an increased active urea transport activity in the initial inner medullary (IM) collecting duct in low-protein diet (LPD) and vitamin D (Vit D) animal models. To investigate the possible mechanisms that cause the urinary concentrating defect an...

With aging, intact parathyroid hormone (iPTH) increases. It plays a crucial role in left ventricular hypertrophy (LVH). Also, 25-hydroxy vitamin D (Vit-D) and iPTH have been observed to be determinants of muscle wasting known as sarcopenia. Fetuin A (FetA), a systemic calcification inhibitor, involves in the development of diastolic heart failure. Hence, we hypothesized that the interplay among...

Background: Beneficial effects of omega-3 polyunsaturated fatty acids (PUFAs) on the male fertility are widely described in the literature. However, there is little information about the effect of dietary n-3/n-6 ratios and Vit E on the male reproduction. The aim of this study was to evaluate the influence of dietary PUFAs on the rat sperm characteristics after eight weeks oil consumption. Mate...
