OBJECTIVES To investigate the associations of serum lipid profile with disease progression in high-risk clinically isolated syndromes (CIS) after the first demyelinating event. METHODS High density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) were obtained in pretreatment serum from 135 high risk patients with CIS (≥ 2 brain MRI lesio...
Emerging evidence from preclinical, clinical and epidemiological studies suggests that vitamin D3 plays vital roles in several diseases in addition to bone disorders. According to new medical evidence, it is being recommended that vitamin D3 intake to be increased for maximal benefits in human health. However, it is necessary to consider potential side effects of increased intake of vitamin D3....
Background and Objective: Coronavirus Disease 2019 (COVID-19) has caused the death of many people, mainly by causing respiratory failure. The method of quarantine for the control of this disease leads to deprivation of vitamin D3 production. In this regard, this study aimed to investigate the relationship between serum vitamin D3 level and risk of COVID-19. Materials and Methods: This case-con...
Specific high-affinity 1,25-dihydroxyvitamin D3 [1,25-{OH)2D3] receptors, which can undergo hormone-dependent activation and nuclear localization, have been demonstrated in a wide variety of established human cancer cell lines and surgically obtained human cancer tissues. 1,25-(OH)2D3 has been reported by some workers to stimulate cancer cell replication at low "physiological" concentrations an...
In this study, we characterized the effects of 25-hydroxyvitamin D3 (25-OH D3) and manipulated dietary cation-anion difference (DCAD) on the performance, urine pH, serum constituents, carcass traits, tissue residual vitamin D and its metabolites, beef tenderness, and mRNA and protein concentrations of Ca-dependent proteinases in LM using 24 cull native Korean cows. The cows were divided into 3 ...
background and aims: 25-hydroxy vitamin d3 is recognized to be an essential element for healthy body; however, its deficiency has been identified as a risk factor for thyroid disease, diabetes mellitus and other autoimmune diseases and infectious diseases. thyroid disease is common in the general population that its prevalence increases proportional to age. subjects with poorly controlled diabe...
The physiological roles played by hepatocytes and nonparenchymal cells of rat liver in the metabolism of vitamin D3 have been investigated. Tritium-labeled vitamin D3 dissolved in ethanol was administered intravenously to two rats. Isolation of the liver cells 30 and 70 min after the injection showed that vitamin D3 had been taken up both by the hepatocytes and by the nonparenchymal liver cells...
The formation of fatty acid esters of vitamin D3 was demonstrated in rat skin exposed to artificial ultraviolet rays by using multi-dimensional high-performance liquid chromatography, ultraviolet spectrophotometry, and gas-liquid chromatography-mass spectrometry. This result indicated that the fatty acid esters of 7-dehydrocholesterol in rat skin (at least 80% of 7-dehydrocholesterol in rat ski...
Background: Inflammatory responses in individuals exposed to sulfur mustard occur in some organs such as lung, skin and eyes. These organs manifest overreaction in cellular and humoral immune responses. Over a long period, the immune responses often continues toward chronic inflammatory processes with some interventions. Obviously some elements have been deregulated. Therefore, this study evalu...
Introduction: Consumption of vitamin D3 is effective to reduce intensity of autoimmune diseases such as multiple sclerosis. Neurons of the central nervous system are constantly exposed to reactive oxygen species and these factors play a key role in the destruction of myelin and damage of axons. The hippocampus is a vital center for learning and memory in central nervous system. This area is ...
