Vitamin E (vit. E) is an antioxidant compound with different kinds including tocopherols and tocotrienols. The major sources of vit. E are vegetable and seed oils. The recommended dietary allowances vary with age, gender, and state of the person. There have been numerous experiments showing beneficial effects of vit. E on immune system, cancer, and coronary artery diseases in the elderly. Moreo...

Vitamin D (vit D) is not only contributed to maintaining normal calcium metabolism, but also is crucial for an extensive range of non-classic actions. The antioxidant effect of vit D is between the newest suggested non-calcemic roles of this compound. According to the vit D deficiency could be related to several chronic diseases such as diabetes, cardiovascular disease and chronic kidney diseas...

The tonoplast monosaccharide transporter (TMT) family comprises three isoforms in Arabidopsis thaliana, and TMT-green fluorescent protein fusion proteins are targeted to the vacuolar membrane. TMT promoter-beta-glucuronidase plants revealed that the TONOPLAST MONOSACCHARIDE TRANSPORTER1 (TMT1) and TMT2 genes exhibit a tissue- and cell type-specific expression pattern, whereas TMT3 is only weakl...

We do not read an article that can make us change practice very often. “Vitamin D deficiency in children and adolescents submitted to hematopoietic stem cell transplantation” by Campos DJ from the Curitiba Pediatric Transplantation group is one of these articles.1 Although vitamin D deficiency has been the theme of many publications in the last few years,2 Brazilians would tend to disregard it ...

BACKGROUND Hoof lesions are very common among sows and have been associated with lameness, early removal and compromised welfare and productivity. Although housing conditions and management can have an external effect on hoof health status, the role of trace mineral intake is vital in developing hoof structure and integrity. Therefore, the objective of this study was to investigate the effect o...

the aim of this study was to evaluate the effects of the addition of antioxidants (vitamin e, β- mercaptoethanol and their combination) to semen extender.  progressive motility, viability and ph of fresh ram semen were examined. ejaculate samples were collected with artificial vagina from three ghezel-merinose rams (3 years old) during non- breeding reproduction season. semen was diluted with a...

Background: Arsenic as a heavy metal exerts malformation and changes in the reproductive system of men via induction of oxidative stress. We sought to investigate the impact of Vitamin C (Vit C), as a potent antioxidant, on sperm quality and testicular tissue in mice that received sodium arsenite. Methods and materials: NMRI mice were classified into four groups: control, sodium arsenite (7 mg...

Vitamin C (Vit C) is considered to be a vital antioxidant molecule in the brain. Intracellular Vit C helps maintain integrity and function of several processes in the central nervous system (CNS), including neuronal maturation and differentiation, myelin formation, synthesis of catecholamine, modulation of neurotransmission and antioxidant protection. The importance of Vit C for CNS function ha...

background: scleroderma is a chronic connective tissue disease of unknown etiology. vitamin d and parathyroid hormone (pth) that play particular functions in calcium and phosphate homeostasis may be involved in the etiology of this disorder. klotho, the co-receptor of the fibroblast growth factor 23 (fgf-23), can interfere with calcium and phosphate metabolism. the purpose of this study was to ...
