5-Aminolevulinic acid (5-ALA) is an essential compound in the biosynthesis of heme, playing a critical role in various physiological processes within the human body. This review provides the thorough analysis of the latest research on the molecular mechanisms and potential therapeutic benefits of 5-ALA in managing metabolic disorders. The ability of 5-ALA to influence immune response and inflammation, oxidative/nitrosative stress, antioxidant system, mitochondrial functions, as well as carbohydrate and lipid metabolism, is mediated by molecular mechanisms associated with the suppression of the transcription factor NF-κB signaling pathway, activation of the transcription factor Nrf2/heme oxygenase-1 (HO-1) system leading to the formation of heme-derived reaction products (carbon monoxide, ferrous iron, biliverdin, and bilirubin), which may contribute to HO-1-dependent cytoprotection through antioxidant and immunomodulatory effects.

This review summarizes the pathogenetic mechanisms that underlie the positive influence of chondroitin sulphates (CSs) on PTOA as means of preventive and therapeutic treatment. Mechanisms of PTOA development involve chondrocytes undergoing various forms of cell death (apoptosis, pyroptosis, necroptosis, ferroptosis and/or necrosis).

Nowadays, the idea of the patient as the main subject of medical care is being established in the public consciousness. It is around the patient that all types of professional medical activities and all forms of relationships with other subjects of modern health care are organized.In the professional sphere, this idea is seen as a principle of patient focus.

The traumatism, including children traumatism, is one of priority problem of health care in the Russian Federation. The indices of children traumatism and disability because of injuries are the most important indices of children health. They characterize quality of child care in family, depend on common norms of public behavior, reflect cases of aggression and violence in relationship of adults and children and in children communities.

The Aim Of The Study: Is to study and compare models of out-of-hospital psychiatric care in different countries-Italy and England.
Unlabelled: In the Italian model of community-based psychiatric care, institutions have been created - homes for permanent residence with a security regime (REMS), the most common of which are intensive (or assertive) treatment in the community and mandatory outpatient treatment. The form of intensive treatment is an active and long-term maintenance and treatment of patients.

In Russia, in conditions of reproductive crisis of modern family, miscarriage IS one of the important problems, in particular habitual miscarriage as significant risk factor of development of maternal and perinatal pathology. The timely identification and medical care support of pregnant women suffering from habitual miscarriage is essential in ensuring and maintaining their reproductive health. To obtain reliable and objective information by control boards on effectiveness of organization and provision of obstetric care to women with diagnosis of habitual miscarriage is an actual task.

Actually, in Russian health care, the organization of community-based medical care of patients with mental disorders is considered as one of requested problems to be resolved. The in-patient substituting forms of specialized primary medical and social care for mental patients create optimal conditions for treatment and rehabilitation of this group of patients without separation from familiar social environment, that in many ways reduces "personality stigmatization" and promotes returning of individual to full-fledged social life, decreasing the load on the most expensive hospital care. One of such organizational forms implemented in Moscow under the new model of provision of mental care is out-patient mental module that provides specialized primary medical and social care and is tested in conditions of basic medical organization.

Objective: To determine the content and role of saturated fatty acids (SFA) in lipid metabolism disorder in patients with alcohol dependence syndrome (ADS).
Material And Methods: A total of 123 men were examined: 44 patients with ADS and 79 healthy people. The patients were examined on the 5-6 day after admission to the hospital.
Following the analysis of the results of quantum chemical simulation of interaction between a GSH molecule and oxygen radicals ∙OH and ∙OO-, it was found that it takes place through the acid-base mechanism, where GSH acts as a base towards ∙OH, and as an acid towards ∙OO-. The results of quantum chemical calculations (electron density redistribution, energy characteristics) were correlated at the time of interaction of a GSH molecule with ∙OH and ∙OO- with a change of macroscopic parameters ofthe process of free oxygen, radical electroreduction in the presence of GSH (potential and maximum current of reduction waves), which is a direct experimental macroscale, evidence of results ofthe conducted nanoscale theoretical simulation.

Previous work has described abnormalities in Ca2+ homoeostasis in sensory and dorsal horn neurons acutely isolated from diabetic rodents. We extended this work by testing the hypothesis that sensory neurons exposed to long-term Type 1 diabetes in vivo would exhibit abnormal axonal Ca2+ homoeostasis and focused on the role of SERCA (sarcoplasmic/endoplasmic reticulum Ca2+-ATPase).

Hyperbilirubinemia in patients with primary biliary cirrhosis is accompanied by a decrease in the concentration of lipid peroxidation products and increase in antioxidant activity of blood serum. Antioxidants play a major role in the prevention of atherosclerosis.

It is well documented that the hormone leptin plays a pivotal role in regulating food intake and body weight via its hypothalamic actions. However, leptin receptors are expressed throughout the brain with high levels found in the hippocampus. Evidence is accumulating that leptin has widespread actions on CNS function and in particular learning and memory.

This multifunctional protein regulates activities of MMPs and possesses growth promoting effect in cell culture, anti-tumoral, anti-apoptotic and anti-angiogenic effects in animal model systems in vivo. It has been shown that this gene is downregulated in cervical carcinomas.

In cultured rat dorsal root ganglion neurones we measured dynamic changes in free Ca(2+) concentration within the ER lumen ([Ca(2+)](L)) in response to activation of inositol-1,4,5-trisphosphate receptors (InsP(3)Rs) and ryanodine receptors (RyRs). We found that both receptors co-exist in these neurones and their activation results in Ca(2+) release from the ER as judged by a decrease in [Ca(2+)](L).

IL-1 exists as two agonist forms (IL-1 alpha and IL-1 beta) present in the cytosol of activated monocytes/macrophages. IL-1 beta is synthesized as an inactive precursor that lacks a signal sequence, and its trafficking does not use the classical endoplasmic reticulum-Golgi route of secretion.

The concentration of free calcium within the lumen of the endoplasmic reticulum ([Ca2+]L) fluctuates between 100 and 1000 microM. High [Ca2+]L provides an electro-driving force for Ca2+ release and supports high Ca2+ diffusion rate within the endoplasmic reticulum lumen. Fluctuations in [Ca2+]L also regulate numerous chaperones, responsible for postranslational protein processing.

Resting [Ca(2+)](L) concentration varied between 60 and 270 microM. Activation of ryanodine receptors by caffeine triggered a rapid fall in [Ca(2+)](L) levels, which amounted to only 40--50% of the resting [Ca(2+)](L) value.

The functional characteristics of liver mitochondria and physical-chemical properties of mitochondrial membranes were studied in S rats with congenitally enhanced capacity to free radical generation in comparison to those in Wistar rats. It was shown previously that intense lipid peroxidation, numerous DNA rearrangements, protein oxidation, morbid states resembling human degenerative diseases and short life-span are characteristic of S rats. In present study we have demonstrated that in S rats at the age of 2-3 months the respiratory rate of the mitochondria in active metabolic state is lower than in Wistar rats, and so are the values for the respiratory control ratio, oxidative phosphorylation and membrane potential.
