Homocysteine : Related Vitamins and Neuropsychiatric Disorders
There is an increasing interest in the connection between the homocysteine metabolism and neuropsychiatric disease with a steeply increasing number of publications. In particular, the association between homocysteine metabolism and cognitive decline/dementia attracts much interest. If simple, non-toxic homocysteine-lowering treatment with vitamins can reduce the incidence of, or delay the onset of dementia, it would have an enormous impact in societies with a rapidly increasing number of elderly at risk for dementia. This book summarises the research within the neuropsychiatric field, but also gives an overview of the underlying biochemistry and of diagnostic aspects.
Homocysteine
Homocysteine is a non-proteinogenic α-amino acid. It is a homologue of the amino acid cysteine, differing by an additional methylene bridge (-CH2-). It is biosynthesized from methionine by the removal of its terminal methyl group. In the body, Homocysteine (HCY) can be recycled into methionine or converted into cysteine with the aid of certain B-vitamins. A high level of Homocysteine in the blood (hyperhomocysteinemia) makes a person more prone to endothelial cell injury, which leads to inflammation in the blood vessels, which in turn may lead to atherogenesis, which can result in ischemic injury. Therefore, hyperhomocysteinemia is a possible risk factor for coronary artery disease (CAD). Coronary artery disease occurs when an atherosclerotic plaque blocks blood flow to the coronary arteries, which supply the heart with oxygenated blood.
Handbook of nutrition and ophthalmology
The Handbook of Nutrition in Ophthalmology is the first general text on nutrition and eye health created for physicians, nutritionists, and researchers. Dr. Richard D. Semba provides important links between the epidemic of obesity and implications it has for eye disease and blindness. The volume addresses three broad themes throughout. The first is that a healthy diet as a major lifelong habit will likely have an impact on reducing a substantial portion of visual impairment and blindness. The second is that a historical perspective is essential to understanding current challenges in ophthalmology, medicine, and public health. The third theme is that many nutrients play a role in oxidative stress and inflammation, and this theory has emerged as a major underlying hypothesis in the pathogenesis of eye diseases.
Chewing gum containing artemisa absinthium (Wormwood) and Vitamin B12 for Anorexia treatment
Anorexia is a medical name for loss of appetite which mean decrease appetite and it is the reason for mental and physical illness. Anorexia can accompany many diseases like infections, covid- 19, cancer, and it is also caused by many drugs. Our objective was to evaluate the level of knowledge about the anorexia among Syrian population, and, to develop chewing gum as health supplement. We used Artemisia absinthium L. (wormwood), vitamin B12 as pharmaceutical supplement ingredients, and, pine resin, or zein protein extracted from com as chewing gum bases...
Bioorganometallic Chemistry
Bioorganometallic Chemistry has become a mature area of science and is comprehensively covered by leading experts in this book. Naturally occuring bioorganometallic complexes, such as vitamin B12 and recently discovered iron and nickel hydrogenases, including a possible role of the latter in the geochemical theory of the origin of life, are considered.
