Vitamin C, also known as ascorbic acid, abounds in nature and is highly labile. It is a water-soluble vitamin that is lost in large amounts during food processing. It is a vitamin whose prescribed requirement across cultures is not uniform. For example , the prescribed requirement of vitamin C in Great Britain is 30mg/day, while in the U.S.A., it is 60mg/day and 100mg/day in Japan. These variations are unusual and point to the need for further research to establish the acceptable RDAs for diverse populations. The RDA for vitamin C should be more than the amount needed to prevent the occurrence of disease. Vitamin C plays significant functions in the body that enhance its role in the health status of the human body. The biochemical functions of vitamin C include: stimulation of certain enzymes, collagen biosynthesis, hormonal activation, antioxidant, detoxification of histamine, phagocytic functions of leukocytes, formation of nitrosamine, and proline hydroxylation amongst others. These functions are related to the health effects of vitamin C status in an individual. In human health, vitamin C has been associated with reduction of incidence of cancer, blood pressure, immunity, and drug metabolism and urinary hydroxyproline excretion, tissue regeneration. This vitamin is needed for the proper metabolism of drugs in the body through adequate hepatic mixed function oxidase system. Epidemiological data have revealed the preventive and curative role of vitamin C on certain disease conditions in the body though controversies still persist. Vitamin C is effective in protecting against oxidative damage in tissues and also suppresses formation of carcinogens like nitrosamines. There is an inverse relationship with blood pressure and both plasma vitamin C and Vitamin C. Vitamin C has a lowering effect on blood pressure, especially on systolic pressure more than a diastolic pressure. Low levels of plasma vitamin C are associated with stroke and with an increased risk of all cause mortality. Increased consumption of ascorbic acid raises serum ascorbic levels and could decrease the risk of death.

Chlorella is one of the most promising species of algae, which is widely cultivated for the industrial production of nutraceuticals in the form of tablets or powder. The value of Chlorella is primarily due to the high content of proteins and lipids (51–58 % and 20–23 % of dry weight respectively), carotenoids and an almost complete set of vitamins. At the same time, in the process of cultivation, a method was developed to enrich algobiomass and its individual components (primarily the lipid fraction) with selenium, zinc, chromium, as important regulatory trace elements. From chlorella, we obtained seleniumlipid, selenium-zinclipid and selenium-chromiumlipid complexes, and their constancy and structure were grounded by chromatographic and mass spectrometric analysis. After feeding healthy rats with a starch solution of selenium-zinclipid complex (1 ml of which contained 0.4 μg of selenium, 2.5 μg of zinc and 0.5 mg of lipids) and selenium-chromiumlipid complex (1 ml contained 1.85 μg of selenium, 1.1 μg of chromium, 0,45 mg of lipids), no signs of intoxication were found (total medium molecular peptides content was reduced to 1.5 times, the content of TBA-active products and diene conjugates were also decreased), antioxidant processes (increase of glutathione content and activity of glutathione peroxidase while reducing the functional role of catalase) were activated (by increasing of succinate dehydrogenase and cytochrome oxidase activity, glutamate dehydrogenase - the way of glutamate formation), which contributed to the successful functioning of the antioxidant system and maintenance of energy and metabolic homeostasis in the body. The obtained results enable the use of biologically active additives from chlorella, enriched with trace elements Se (IV), Zn (II) and Cr (III), as promising therapeutic and prophylactic substances, which will contribute to the successful functioning of the antioxidant system, maintain energy metabolism and metabolism correction of pathological processes, which is the basis for further studies of the biological activity of the complexes under study.

According to modern notions, atherosclerosis is a complex multifactorial process in which the mechanisms of development involved endothelial dysfunction, inflammation, dyslipidemia, disorders of the blood coagulation system, and the like. Polyunsaturated fatty acids are a source of biologically active substances that regulate metabolic processes in the body. It is known that during the development of inflammation, biologically active agents are synthesized and accumulated, which both provide a protective function, and play the role of triggers or lead to the development of additional alteration and the formation of pathological systems. Purpose of the study. The purpose of the work is to study the functional state of the lipid transport system and to ascertain the role of polyunsaturated fatty acids in the mechanisms of atherosclerosis. The analysis of the functional state of the lipid-transport system of 221 patients with diffuse cardiosclerosis with different nosological forms revealed a disturbance of direct and reverse transport of cholesterol, but with varying degrees of orientation. Significant increase in the content of saturated fatty acids by 7.51% and reduction of unsaturated. Reducing the level of polyunsaturated fatty acids is a consequence of increased formation of prostaglandins and leukotrienes in inflammatory processes of the vascular wall, and indicates a disbalance in the regulation of lipid homeostasis. The deficiency in polyunsaturated fatty acid cells for many years models the high potential of endothelial dysfunction, which can be a pathogenetic mechanism not only for atherosclerotic lesions, but also for inflammation of the vessels. Conclusion. The recognition of atherogenesis as an active process rather than a cholesterol storage disease has highlighted some key inflammatory mechanisms. In our opinion, the local violation of the transport of lipids in the tissue is at the heart of the atherosclerotic lesion of the vascular wall, which develops irrespective of inflammation in the vessel wall, but substantially potentiates them due to the action of inflammatory mediators.

Chocolate is the most staple and consumed confectionery product in Russia and the world. The determination of the beneficial properties of such a product as chocolate is an important and regular process of food institutions in every country, since new lines of already well-known manufacturers and new manufacturers with an innovative assortment are added to the retail assortment. Today, it is very relevant and important to understand the impact of new products on human health. In this regard, in order to provide complete information on a specific product, it is necessary to know its composition, ingredients and their effect on the body separately and within the framework of a specific product. Along with its beneficial properties, chocolate can also affect health negatively. It is necessary to understand the mechanism of the effect of chocolate on human health when consumed and to assess the risks that may arise subsequently after its active consumption.

The aim of this paper is to characterize the biologically active peptide – apelin, and its previously identified APJ receptor. Gene and protein expression of apelin/APJ system has been detected in many tissues and organs of the body such as: adipose tissue, stomach, liver, pancreas, heart, lungs, uterus, ovaries, brain or spinal cord. The results of recently published papers show the role of the apelin/APJ system in numerous physiological and pathological processes in the body, including nociceptive processes. This paper discusses the physiological and molecular mechanisms of the apelin/APJ system, with particular emphasis on its role in inflammatory and neuropathic pain, as well as in the effectiveness of opioids. In addition, the clinical aspect of this system in pain processes is presented.

Steroid sulfatase (STS) is responsible for the hydrolysis of aryl and alkyl steroid sulfates and therefore has a pivotal role in regulating the formation of biologically active steroids. The enzyme is widely distributed throughout the body, and its action is implicated in physiological processes and pathological conditions. The crystal structure of the enzyme has been resolved, but relatively little is known about what regulates its expression or activity. Research into the control and inhibition of this enzyme has been stimulated by its important role in supporting the growth of hormone-dependent tumors of the breast and prostate. STS is responsible for the hydrolysis of estrone sulfate and dehydroepiandrosterone sulfate to estrone and dehydroepiandrosterone, respectively, both of which can be converted to steroids with estrogenic properties (i.e., estradiol and androstenediol) that can stimulate tumor growth. STS expression is increased in breast tumors and has prognostic significance. The role of STS in supporting tumor growth prompted the development of potent STS inhibitors. Several steroidal and nonsteroidal STS inhibitors are now available, with the irreversible type of inhibitor having a phenol sulfamate ester as its active pharmacophore. One such inhibitor, 667 COUMATE, has now entered a phase I trial in postmenopausal women with breast cancer. The skin is also an important site of STS activity, and deficiency of this enzyme is associated with X-linked ichthyosis. STS may also be involved in regulating part of the immune response and some aspects of cognitive function. The development of potent STS inhibitors will allow investigation of the role of this enzyme in physiological and pathological processes.

: Xanthine oxidase (XO) is an essential enzyme in catalyzing hydroxylation of hypoxanthine to xanthine and uric acid in the kidney. Excessive formation of uric acid can lead to hyperuricemia (HUA), a condition caused by excess uric acid contamination in the blood.HUA is responsible for various diseases in the body, such as gout, cardiovascular, and renal failure. It is also associated with numerous inflammatory diseases and their metabolic pathways, including tumors, chronic hypoxia, renal injury, and hypertension. XO is a superoxide producing enzyme usually confined to lungs, liver, and blood serum. Blood assay and diagnostics for XO help in a better understanding of its associated diseases in the human body. The mechanism of how XO is released in the bloodstream is a matter of debate in medical science. In the current review article, we comprehensively discussed the role of XO in human health, inhibitors, and their regulation, isolation, and extractions of inhibitors from plants, types, and their activities towards the human health perspective are concerned.

Anti-idiotypic antibodies (anti-IDs) were discovered at the very beginning of the 20th century and have attracted attention of researchers for many years. Nowadays, there are five known types of anti-IDs: α, β, γ, ε, and δ. Due to the ability of internal-image anti-IDs to compete with an antigen for binding to antibody and to alter the biologic activity of an antigen, anti-IDs have become a target in the search for new treatments of autoimmune illnesses, cancer, and some other diseases. In this review, we summarize the data about anti-IDs that mimic the structural and functional properties of some bioregulators (autacoids, neurotransmitters, hormones, xenobiotics, and drugs) and evaluate their possible medical applications. The immune system is potentially able to reproduce or at least alter the effects of any biologically active endogenous or exogenous immunogenic agent via the anti-idiotypic principle, and probably regulates a broad spectrum of cell functions in the body, being a kind of universal remedy or immunacea, by analogy to the legendary ancient goddess of universal healing Panacea (Πανάκεια, Panakeia in Greek) in the treatment and prevention of diseases, possibly including non-infectious somatic and even hereditary ones.
