The first part of the review presents data on the content of magnesium in organs and tissues of the human body, the role of magnesium in the implementation of multiple functions, and the peculiarities of its intake and excretion from the body. A significant part of the review is devoted to methods for determining the concentration of magnesium in biological fluids of the human body. The advantages, disadvantages and limitations of various methods are presented. The most common methods for studying the concentration of magnesium in biological fluids of the body, which are used in clinical medicine all over the world, are photometric methods with dyes. The role of the fraction of ionized magnesium in the body, the content of which is determined electrochemically, is still uncertain. Cellular magnesium studies are extremely complex and time-consuming. Cells of different organs and tissues normally contain very different amounts of magnesium. It is not possible to judge about the presence of magnesium deficiency in the body by its concentration in plasma or serum. To detect a decrease in the tissue content of magnesium, tests with magnesium load and the subsequent observation of the rate of its excretion from the body are used. The causes for the development of hypomagnesemia are extremely numerous. The main of them are: any severe stress, restriction of magnesium intake into the body, an increase in its losses through the gastrointestinal tract and the kidneys in various pathological conditions. The formation of hypomagnesemia is facilitated by therapy with numerous medications, which are very widely used in clinical practice, and especially in the intensive care. Studies on the distribution of magnesium in the body after its intravenous administration have shown that, despite the large size of hydrated magnesium ions, they can not only paradoxically quickly spread in the extracellular water space, but most likely are also able to quickly penetrate through cell membranes, spreading in the intracellular water compartment.

Aims: The aim of the experiments was to find out the factors on which age-related sensitivity to the occurrence of BPH depends. Methods: 45 male Wistar rats aged 3 and 24 months were used. In each age group there were intact rats and animals with induced BPH (by surgical castration + testosterone injections, 25 mg/kg x 7). On the 36th day of the experiment, blood was taken from rats to determine serum testosterone, cholesterol, triglycerides and glucose; then the animals were autopsied, their prostates were weighed, and their morphology was studied. Results: Young mature intact rats had much higher testosterone levels (6.2±0.93 nmol/l) than old intact (3.8±0.55 nmol/l), while the ratio of prostate weight was inverse. The weight of the prostate and prostatic index in old rats with induced BPH was significantly higher not only in comparison with the old intact rats but also with young animals after BPH induction. Morphologically, the inflammatory foci were determined not only in the prostates of old rats, which induced BPH, but also in intact animals. Besides in old intact rats, the foci of prostate hyperplasia were often noted. Conclusions: Our experimental model indicates the important role of non-bacterial prostatitis in the pathogenesis of BPH. No metabolic disorders in BPH induction were revealed. The sensitivity of the prostate of old rats to BPH development is increasing despite the low concentrations of testosterone in the body. Age sensitivity to BPH is probably determined by a higher expression of androgen receptors in old animals.

Mammalian, or mechanic, target of rapamycin (mTOR) signaling is a crucial factor in the regulation of the energy balance that functions as an energy sensor in the body. The present review explores how the mTOR/S6k intracellular pathway is involved in modulating the production of different signals such as ghrelin and nesfatin-1 in the gastrointestinal tract to regulate food intake and body weight. The role of gastric mTOR signaling in different physiological processes was studied in depth through different genetic models that allow the modulation of mTOR signaling in the stomach and specifically in gastric X/A type cells. It has been described that mTOR signaling in X/A-like gastric cells has a relevant role in the regulation of glucose and lipid homeostasis due to its interaction with different organs such as liver and adipose tissue. These findings highlight possible therapeutic strategies, with the gut–brain axis being one of the most promising targets in the treatment of obesity.

ANGPTL8 is an important cytokine, which is significantly increased in type 2 diabetes mellitus (T2DM), obesity and metabolic syndrome. Many studies have shown that ANGPTL8 can be used as a bio-marker of these metabolic disorders related diseases, and the baseline ANGPTL8 level has also been found to be positively correlated with retinopathy and all-cause mortality in patients with T2DM. This may be related to the inhibition of lipoprotein lipase activity and the reduction of circulating triglyceride (TG) clearance by ANGPTL8. Consistently, inhibition of ANGPTL8 seems to prevent or improve atherosclerosis. However, it is puzzling that ANGPTL8 seems to have a directing function for TG uptake in peripheral tissues; that is, ANGPTL8 specifically enhances the reserve and buffering function of white adipose tissue, which may alleviate the ectopic lipid accumulation to a certain extent. Furthermore, ANGPTL8 can improve insulin sensitivity and inhibit hepatic glucose production. These contradictory results lead to different opinions on the role of ANGPTL8 in metabolic disorders. In this paper, the correlation between ANGPTL8 and metabolic diseases, the regulation of ANGPTL8 and the physiological role of ANGPTL8 in the process of glucose and lipid metabolism were summarized, and the physiological/pathological significance of ANGPTL8 in the process of metabolic disorder was discussed.

Amino Acid Tryptophan

Serotonin is a biogenic amine synthesized from the essential amino acid tryptophan. Because serotonin cannot cross the blood-brain barrier, it functions differently in neuronal and non-neuronal tissues. In the CNS, serotonin regulates mood, behavior, appetite, and energy expenditure. Although most serotonin in the body is synthesized at the periphery, its biological roles have not been well elucidated. Older studies using chemical agonists and antagonists yielded conflicting results, because the complexity of serotonin receptors and the low selectivity of agonists and antagonists were not known. Several recent studies using specific knock-out of serotonin receptors have been performed to assess the role of peripheral serotonin in regulating energy metabolism. This review discusses (1) the tissue-specific roles of peripheral serotonin in regulating energy metabolism, (2) the mechanism by which dysfunctional peripheral serotonin signaling can progress to metabolic diseases, and (3) how peripheral serotonin signaling could be a therapeutic target for metabolic diseases.

The role of central tolerance induction has recently been revised after the discovery of promiscuous expression of tissue-restricted self-antigens in the thymus. The extent of tissue representation afforded by this mechanism and its cellular and molecular regulation are barely defined. Here we show that medullary thymic epithelial cells (mTECs) are specialized to express a highly diverse set of genes representing essentially all tissues of the body. Most, but not all, of these genes are induced in functionally mature CD80hi mTECs. Although the autoimmune regulator (Aire) is responsible for inducing a large portion of this gene pool, numerous tissue-restricted genes are also up-regulated in mature mTECs in the absence of Aire. Promiscuously expressed genes tend to colocalize in clusters in the genome. Analysis of a particular gene locus revealed expression of clustered genes to be contiguous within such a cluster and to encompass both Aire-dependent and –independent genes. A role for epigenetic regulation is furthermore implied by the selective loss of imprinting of the insulin-like growth factor 2 gene in mTECs. Our data document a remarkable cellular and molecular specialization of the thymic stroma in order to mimic the transcriptome of multiple peripheral tissues and, thus, maximize the scope of central self-tolerance.

Bronchial asthma (BA) and obesity are one of the major modern problem, requiring the development of an effective therapeutic strategy. The frequent combination of these diseases in one patient indicates the general pathophysiological mechanisms and future study for targeted drug exposure are needed. The endocannabinoid system is involved in a variety of physiological and pathological processes and can be considered as a general mechanism and a potential therapeutic target in asthma and obesity, the receptors of the system are expressed in many central and peripheral tissues. This signal system modulates the functions of the autonomic nervous system, immune system and microcirculation, plays an important role in the regulation of energy balance, metabolism of carbohydrates and lipids. The main research aimed at studying the functioning of this system was focused on neurology and psychiatry, while numerous scientific data demonstrate the importance of the participation of this system in the pathogenesis of other diseases. In particular, this system is involved in the mechanisms of obesity. The role of the endocannabinoid system in the pathogenesis of asthma is actively studied. The wide prevalence of the endocannabinoid signaling system and its regulatory role in the body opens up prospects for therapeutic effects in the treatment of asthma and obesity, as well as the possible phenotype of asthma, combined with obesity. The review is devoted to modern ideas about endocannabinoids, their receptors, mechanisms of action and their role in the pathophysiology of asthma and obesity. The therapeutic prospects and difficulties associated with the use of endocannabinoids and phytocannabinoids in medicine are discussed.
