Published: May 2004

A great number of epidemiologic and experimental results of scientific research led to the conclusion, that hyperhomocysteinemia could be possible risk factor for the cardiovascular diseases development in patients suffering from the homocysteinuria and in all the population, because of homocysteine's ability to the activation of the thrombogenesis processes and to the creation of the atherosclerotic changes. Furthermore, the elevated homocysteine concentration exacerbates the effects of the other atherosclerogenous factors, such as tobacco smoking or arterial hypertension. The increased mortality caused by the cardiovascular diseases was observed in patients with the homocysteine concentration elevated above 15 micromol/l on an empty stomach and 38 micromol/l after the methionine intake (the mortality was twice higher). The concentration aimed 10 to 15 micromol/l is assumed to be the normal high concentration. There were no screening researches led on the population for the showing the number of people with the increased homocysteine concentration, however such kind of investigation could be recommended in patients with diabetes, kidney diseases, family history with reported cardiovascular diseases, heart and other organs transplantation, and in patients with the constant intake medicaments increasing the homocysteine concentration. We have no results of prospective research conducted on the numerous patient group, which could document the profits resulted by the treatment of the hyperhomocysteinemia in the primary and secondary prophylactic of the cardiovascular disease.

Objectives: Many cancer cells depend on exogenous methionine for proliferation, whereas non-tumorigenic cells can divide in media supplemented with the metabolic precursor homocysteine. This phenomenon is known as methionine dependence of cancer or methionine addiction. The underlying mechanisms driving this cancer-specific metabolic addiction are poorly understood.

This case describes a patient with pancreatic exocrine insufficiency and persistently elevated serum vitamin B12 concentrations that were not due to supplementation or associated with hepatic or hematological pathology. Laboratory investigations suggested the presence of macro-B12 as the cause of this patient's raised serum vitamin B12. Macro-B12 is often formed when vitamin B12-vitamin binding proteins (transcobalamin and haptocorrin) complex with immunoglobulins.

Vitamin Metabolism and Its Dependency on Genetic Variations Among Healthy Adults: A Systematic Review for Precision Nutrition Strategies.

University Centre for Prevention and Sports Medicine, Department of Orthopaedics, Balgrist University Hospital, University of Zurich, 8008 Zurich, Switzerland.

Background/objectives: In recent years, there has been a growing interest in precision nutrition and its potential for disease prevention. Differences in individual responses to diet, especially among populations of different ancestry, have underlined the importance of understanding the effects of genetic variations on nutrient intake (nutrigenomics). Since humans generally cannot synthesize essential vitamins, the maintenance of healthy bodily functions depends on dietary vitamin intake.

Untreated hyperprolactinemia and autoimmune thyroiditis (Hashimoto's disease) seem to increase cardiometabolic risk. The cardiometabolic effects of cabergoline were less significant in young women with concurrent euthyroid Hashimoto's illness. This study sought to investigate if the detrimental effects of this condition on cabergoline efficacy are also evident in postmenopausal women.

A Redox-Active Copper Complex for Orthogonal Detection of Homocysteine Involving Fluorescence and Electrochemical Techniques.

Small

January 2025

Analytical & Environmental Science Division and Centralized Instrument Facility, CSIR-CSMCRI, G. B. Marg, Bhavnagar, 364002, India.

The present work reports the synthesis, characterization, and excited state photo-physical studies of two copper(II) compounds, 1 & 2, which show interference-free emission with homocysteine (Hcy). Cu(II) complexes offer an orthogonal detection strategy involving fluorescence and electrochemical methods, paving the way for improved point-of-care diagnostics and early cardiovascular diseases intervention. The reduction-induced emission enhancement (RIEE) of Cu complexes facilitates the fluorescence measurement of Hcy at physiological pH.
