diseases of heart and stroke cause most deaths in both sexes of all ethnic groups. for more than 40 years epidemiological studies, experimental studies, and clinical trials have shown that numerous dietary risk factors affect serum lipids, atherogenesis and coronary heart disease (chd). substantial interest has recently focused on the hypothesis that the naturally occurring antioxidant vitamins...
objective(s):multiple sclerosis (ms) is a demyelinating disease. the prevalence of ms is highest where environmental supplies of vitamin d are low. cognitive deficits have been observed in patients with ms. oxidative damage may contribute to the formation of ms lesions. considering the involvement of hippocampus in ms, an attempt is made in this study to investigate the effects of vitamin d3 on...
Homogenized milks at 0.5 and 2.5% fat content were each fortified with three levels of Vitamin A palmitate at 3000, 4000 and 5000 IU/L. Vitamin was added just before homogenization and then pasteurized milks were packed in polymeric pouches and glass bottles. All samples were refrigerated at 4-5 °C for 48 hours. Any reduction in vitamin A level was monitored using HPLC, while sensory evaluation...
Introduction: Epilepsy is regarded as one of the prevalent neurological disorders in children. The role of anti-oxidants in protection of epilepsy has been discussed in several studies. Vitamin E can be mentioned as a natural antioxidant to neutralize free radicals. Therefore, the present study aimed to evaluate the effects of vitamin E on oxidative stress markers such as malone dialdehyde(MDA)...
Background and purpose: Vitamin K2 is one of the derivatives of vitamin K belonging to fat-soluble vitamins’ family. Other derivatives of vitamin K in the brain must be converted to K2 and this can reflect its importance in the nervous system. There are some evidences on analgesic effects of vitamin K. This study investigated the effects of intrathecal administration of vitamin K2 on pain in th...
Background: Oxidative modification of low-density lipoprotein (LDL) appears to be an early step in the pathogenesis of atherosclerosis. Meanwhile, myeloperoxidase (MPO)-catalyzed reaction is one of the potent pathway for LDL oxidation in vivo. The aim of this study was to evaluate in vitro antioxidant effects of vitamins C and E on LDL oxidation mediated by MPO. Methods: MPO was isolated from f...
Background Vitamin D deficiency is associated with physiologic changes that are similar to pathogenesis of preeclampsia. Although association of vitamin D and preeclampsia has been studied previously, their results are not consistent. The aim of this study was to investigate the relationship of serum vitamin D and calcium with preeclampsia severity. Materials and Methods: This case- control st...
Abstract Background and Objective: C- reactive protein (CRP), as an acute phase reactant and a reliable marker of inflammation, increases due to inflammatory diseases such as Rheumatoid Arteritis and infectious conditions. New evidence shows that Vitamin D may have important effects on adjusting and reducing the Immune Responses. The aim of this study was to evaluate the association between...
Background and purpose: Vitamin D deficiency has been shown to be linked to evolution of ischemic stroke, but the data regarding the association between stroke severity and vitamin D level is scarce. Materials and methods: Patients with first-ever acute ischemic stroke in the middle cerebral artery (MCA) territory within 7 days after the stroke were recruited. The control group included age an...
Background and Objectives: Due to the good solubility of vitamin D in oils, oil products can be addressed as one of the most suitable fortification vehicle. However, sustainability and loss of vitamin D during food storage is one the major concerns for the food policymakers and producers. Therefore, the objectives of this study was to fortify and compare the stability of vitamin D3 in sunflower...
