Resumen

[Truncated abstract] An elevated total plasma homocysteine concentration (tHcy) is associated with an increased risk of myocardial infarction and ischemic stroke. Folic acid, vitamin B6 and B12 supplements significantly reduce tHcy even in people who are not overtly vitamin deficient. If homocysteine is a causal risk factor for atherothrombotic events, treatment with B-vitamins might prove a simple and cost-effective means to reduce cardiovascular risk. However, it remains unclear whether elevated tHcy causes atherosclerosis or is simply a risk marker. To prove that homocysteine is a modifiabl

Resumen

Considerable interest exists with regard to the putative therapeutic role of ascorbic acid in various conditions. A condition which has received much attention is cancer, as it is reported that ascorbic acid may be a prophylactic against cancer development. However, the actual involvement of ascorbic acid, an oxidizing/reducing agent, in the development and progression of tumours is presently a subject of much speculation. This study initially addressed the effect of ascorbic acid supplementation over a nutritional concentration range (0 - 100 μg/ml) on the in vitro growth of non-malignant LLC

Resumen

Since vitamin D deficiency is common at birth, the objective of this study was to test if postnatal vitamin D supplementation would normalize bone mineralization. Forty guinea pigs were randomized to receive a diet with or without vitamin D3 during pregnancy. Newborn pups were randomized to receive 10 IU of vitamin D3 or a placebo daily until d28. Measurements at birth and d28 included whole body and regional bone mass, osteocalcin and deoxypyridinoline, plus biomechanical testing of excised tibias and femurs. Offspring from deficient sows had lower body weight, whole body and tibia bone miner

Resumen

Objective: Acute lower respiratory infection (ALRI) is the leading cause of mortality in pediatric group all around the world. Vitamin D has been demonstrated to play a possible role in the prevention of ALRI in children because of its physiological importance in the immune system. This systematic review aims to explore the protective role of vitamin D on ALRIs among children and its preventive effectiveness by synthesizing RCTs. And the other objective is to determine dosage of vitamin D with the best effect by investigating the association of different level of vitamin D supplementation wi

Resumen

Early cortical injury has been attributed to the consequential effects of various factors, such as alcohol, drug addiction, smoking, and inadequate nutrient intakes during periods of pregnancy and lactation, or delivery of infants by forceps, and premature deliveries. These are only a few examples of circumstances, or "injury", that may result in disorders ranging from mild learning difficulties to aggressive behaviour. Injury to the cortex during the early years of development has been know to result in poor behavioural outcome into adulthood. Presently, the most common form of treatment incl

Texto completo

Resumen

The active form of Vitamin D (VD3) has been shown to induce pro-apoptotic and anti-proliferative effects in several mammalian cancer cell types. The molecular mechanisms of tumor suppression, however, are not clearly understood. Previous research has shown that head and neck squamous cell carcinoma (HNSCC) responds to VD3. This thesis used both in vivo and in vitro models to examine the effect of VD3 in HNSCC. Former work in the Albala laboratory showed that hamsters that received systemic VD3 and topical treatment of 7,12-dimethylbenz(a)anthracene (DMBA) to the buccal pouch showed no or delay

Resumen

[Truncated abstract] Vitamin E is comprised of a family of tocopherols (TOH) and tocotrienols. The most studied of these is [alpha]-tocopherol ([alpha]-TOH), as this form is retained within the body and any deficiency of vitamin E is corrected with this supplement. [alpha]-TOH is a lipid-soluble antioxidant required for the preservation of cell membranes and potentially acts as a defense against oxidative stress. Individuals who have a primary vitamin E deficiency such as low birth weight infants, secondary vitamin E deficiency due to fat malabsorption such as in abetalipoproteinaemia, or a ge

Resumen

Falls in the older population have devastating consequences on the psychological and physiological health of the individual. Due to the complexity of interacting factors associated with ageing, pathology and falling episodes, determination of a primary cause or set of causes has been difficult to establish. Deficits in components of neuromuscular control have been widely studied with the coordinated interaction of sensory and motor system components being presented as a fundamental factor in the reduction of falling episodes.

Resumen

Despite numerous studies have demonstrated an association of type 2 diabetes mellitus (T2DM) and osteoporosis, the underlying mechanism connecting these two conditions remains elusive. Clinically, combined calcium and vitamin D supplement is the commonest osteoporosis therapy; however, recent studies have suggested an increase in cardiovascular risks associated with calcium plus vitamin D supplementation. Therefore, an alternative strategy in treating osteoporosis patients with T2DM is urgently needed. In this study, we hypothesized that combined administration of menaquinone-4 (vitamin K₂, bi

Blood samples were obtained before and after dialysis during two separate dialysis sessions to establish baseline measurements. For the next two months, subjects consumed 400 IU RRR-α-tocopherol daily. At one month and two months of supplementation, blood samples were also obtained before and after dialysis.

HD patients were categorized into two groups according to their plasma ascorbic acid levels. We found that only the vitamin C sufficient group (>40 μM, Group I) had reliable measurements of eryth

Adult spring chinook salmon were also artificially infected with the EIBS virus. Adult male chinook had higher prevalences of EIBS inclusion bodies than females.

M.Tech. (Homoeopathy)<br>Psychological stress refers to an individual’s interaction with what he perceives as adverse or threatening phenomena of the external environment (stimulus) and the ensuing physiological response that occurs within the body. Although the stimulus itself may not be harmful, the physiological reaction of the individual to the perceived threat may lead to health consequences. University students may experience greater levels of stress than the average population. They may also experience symptoms of anxiety, irritability, sleep disturbances and impaired memory due to psyc
