BACKGROUND: An increased serum total homocysteine (tHcy) concentration is typically associated with genetic defects involved in Hcy metabolism or related nutritional deficiencies. In this study, the combined effects of methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and folate and vitamin B12 deficiency on serum total Hcy (tHcy) levels were evaluated in a healthy Chinese population in Yunnan Province, China. METHODS: The MTHFR C677T polymorphism was genotyped in 330 volunteers (164 men and 166 women) using polymerase chain reaction-restriction fragment length polymorphism analysis...

BACKGROUND: The traditional duodenal switch is performed using a Roux-en-Y configuration. This procedure has proven to be the most effective procedure for long-term weight loss and co-morbidity reduction. Recently, stomach intestinal pylorus sparing surgery (SIPS) has been introduced as a simpler and potentially safer variation of the duodenal switch (DS). It is a single anastomosis end-to-side proximal duodeno-ileal bypass with a sleeve gastrectomy. In this study, we compare our outcomes between biliopancreatic diversion with duodenal switch (BPD-DS) and SIPS at 2 years...

Although the etiology and pathology of autism spectrum disorder (ASD) is still poorly understood, a number of environmental, anthropological, neurobiological and genetic factors have been related to the pathophysiology of ASD, even the impact of oxidative stress response related to the environment and nutrition intake. Usual recommended dietary habits are based on the combination of behavioral and dietary or nutraceutical interventions together with pharmacotherapy. Investigations about a reliable relationship between diet and ASD are still lacking...

Nutritional status of lactating women is considered to be a quantitative indicator reflecting the status of reproductive health. To improve nutrition status of lactating women and promote breastfeeding through targeted intervention measures, their dietary and nutritional situations, and related problems, should be fully understood. Generally, energy and macronutrient intake of lactating women can reach or exceed recommended levels, especially during the first month postpartum. However, the intake of some micronutrients is difficult to meet the requirement...

Nitrous oxide is commonly used as an analgesic and anaesthetic agent. Nitrous oxide is also in use in industry as an aerosol propellant and is now recognised as a recreational drug whose use is growing, especially among the young. Nitrous oxide from whipped cream canisters is inhaled to produce a dissociative, intoxicated state. Nitrous oxide is known to inactivate vitamin B12 via oxidation, which can precipitate a demyelinating myelopathy akin to the classical B12 deficiency syndrome, subacute combined degeneration of the spinal cord...

BACKGROUND/OBJECTIVES: Observationally, homocysteine is positively associated with ischemic heart disease (IHD) and unhealthy lipids; folate and vitamin B12, which reduce homocysteine, are associated with lower IHD risk and healthy lipids. Randomized controlled trials have shown no benefits of folate and vitamin B12 for IHD. To clarify the role of these potential targets of intervention in IHD we assessed how genetically determined homocysteine, folate and vitamin-B12-affected IHD and lipids...

REVIEW
Luciana Hannibal, Henk J Blom
Nutritional and genetic deficiencies of folate and vitamin B12 lead to elevation of cellular homocysteine (Hcy), which translates in increased plasma Hcy. The sources and role of elevated plasma Hcy in pathology continues to be a subject of intense scientific debate. Whether a cause, mediator or marker, little is known about the molecular mechanisms and interactions of Hcy with cellular processes that lead to disease. The use of folic acid reduces the incidence of neural tube defects, but the effect of Hcy-lowering interventions with folic acid in cardiovascular disease and cognitive impairment remains controversial...

REVIEW

The function of one-carbon metabolism is that of regulating the provision of methyl groups for biological methylation reactions including that of DNA and histone proteins. Methylation at specific sites into the DNA sequence and at histone tails are among the major epigenetic feature of mammalian genome for the regulation of gene expression. The enzymes within one-carbon metabolism are dependent from a number of vitamins or nutrients that serve either as co-factors or methyl acceptors or donors among which folate, vitamin B12, vitamin B6, betaine, choline and methionine have a major role...

Plant-based diet is an old-new trend in nutrition. In this review based on a historical context, we wish to introduce this popular nutritional trend. Our aim is to present plant-based diet as a primary measure for prevention. We intend to critically analyse some past stereotypes related to plant-based diet - whose main components include fruits, vegetables, whole grains, legumes, nuts and seeds - according to the literature (e.g. protein, vitamin B12, folic acid, and iron intake) by doing so we wish to create an adequate conceptual basis for its interpretation...
