Demographic Aging

From the biomedicine point of, view ageing is a natural process, characterized by a gradual decrease in the physiological integrity and adaptive abilities of the body, leading to a violation of its functions and an increase in the risk of death with age. Demographic aging of the population is a serious socio-economic problem, both in Russia and around the world. The main cellular and molecular signs of aging include genome instability, telomere shortening, epigenetic alterations, impaired proteostasis, impaired nutrient recognition, mitochondrial dysfunction, cellular aging, the stem cell pool depletion and changes in intercellular interaction, extracellular matrix rigidity, as well as activation of retrotransposons and chronic inflammation. For these reasons, in modern healthcare, preventing premature aging and treating age-related diseases is becoming a priority task. This review presents modern approaches to the quantitative assessment of the aging process using aging biomarkers as functional parameters reflecting the biological organism age at the molecular, cellular, and organismal levels. This work also considers the actual non-drug and drug interventions allowing to slow down the development of age-associated pathological processes, allowing you to increase the quality and duration of life.

Patients With Diabetes

In recent decades, there has been a significant increase in the incidence and prevalence of diabetes mellitus. Diabetes mellitus is characterized by the development of vascular complications leading to early disability and a decrease in the life expectancy of patients. Aging of the body inevitably leads to the occurrence of age-related diseases, including the cardiovascular system, and increases the risk of death. Metabolic and structural and functional disorders of the cardiovascular system arising in diabetes mellitus have common pathophysiological mechanisms with aging of the body. Chronic hyperglycemia can accelerate the aging process and play a decisive role in the occurrence and prognosis of cardiovascular events in patients with diabetes mellitus. Achieving target glycemic values is an important step towards preventing vascular complications in patients with diabetes mellitus. Improved models of glucometers, equipped with a number of additional functions, allow for structured self-control of glycemia, analyze the data obtained and carry out timely correction of therapy, actively involve patients in the process of diabetes management, which will significantly increase the efficiency of disease management, reduce the risk of complications in patients and improve the quality of life.

Aging is characterized with a gradual aggravation of organ function throughout life and can occur both physiologically and prematurely. With premature aging there is an early decrease in the adaptive mechanisms of all physiological systems of the body, there is a significant reduction in physical and mental activities, that contributes to the early development of age−related pathology. Genetic and epigenetic factors, as well as environmental ones can be the causes of different rates of aging. It is not possible to accurately determine the onset of old age by biological characteristics, because people with the same calendar age are not always the same as for biological one. To establish the association of age−related disease factors with the markers of premature aging and biological age in the patients of various age groups, a study was performed in the patients aged 25−44 and 45−59 years with moderate cardiovascular risk in accordance with the SCORE scale. The primary task for predicting and preventing the age−associated diseases is to identify genetic, molecular and cellular factors that determine the rate of aging and increase the risk of age−associated diseases. The role of cardiovascular risk factors in premature aging has been determined. It is established that the most important factors that lead to an increase in biological age and formation of age−associated diseases are the disorders of lipid and carbohydrate metabolism and level of oxidative stress, importance of which progresses with age. The relationship between cardiovascular risk factors and biological age, estimated with different methods, their influence on telomere length, that allows the designing of an algorithm to determine the markers of premature aging in different age groups for early and effective prevention of metabolic−associated diseases, has been established. Key words: biological age, cardiovascular risk, premature aging, telomere length.

Daunting Task

In connection with the increase in the average age of the world's population, the problem of preventing premature aging and the treatment of age-related diseases is coming to the fore. The main direction in the implementation of this goal is to influence the key molecular mechanisms of aging in order to suppress pathological processes and activate the defense systems of the cell and the body as a whole. In order to solve this daunting task, it is necessary to have in the arsenal not only various means of intervention in the aging process, but also diagnostic methods that would allow to fully verify these processes and evaluate the effectiveness of medical interventions.

The Impact

The review summarizes the modern knowledge of the impact of day-night, light-darkness rhythm disorders on the aging process and on the risk of development of the age-related conditions. Significant evidence has been obtained of that the constant artificial illumination and the daylight of the North has a stimulating effect on the occurrence and de-velopment of tumours in laboratory animals. It has been shown that long-term shift work, trans-meridian flights (jet-lag) and insomnia increase the risk of cardiovascular diseases, diabetes mellitus, and ma-lignancies in humans. Particular attention is given to the studies where the relationship between light intensity, light wavelength and its ability to suppress the synthesis of melatonin produced at night in the pineal gland, are investigated. It has been established that melatonin synthesis is most effectively suppressed with blue light sources of a wave-length from 446 to 477 nm. The use of exogenous melatonin prevents premature aging of the reproductive system and the body as a whole prevents the development of immunesuppression, metabolic syndrome and tumours caused by light pollution. An urgent task is to develop recommendations for optimizing the illumination of workplaces and res-idential premises, of cities and towns as a preven-tion measure for premature aging and age-related pathology, which, ultimately, will contribute to the long-term maintaining of performance and improv-ing the quality of life.

Aging is a multi-factor biological process that inevitably affects everyone. Degenerative processes, starting at the cellular and molecular levels, gradually influence the change in the functional capabilities of all organs and systems. Progeroid syndromes (from Greek. progērōs prematurely old), or premature aging syndromes, represent clinically and genetically heterogeneous group of rare hereditary diseases characterized by accelerated aging of the body. Progeria and segmental progeroid syndromes include more than a dozen diseases, but the most clear signs of premature aging are evident in Hutchinson-Guilford Progeria Syndrome and Werner Syndrome. This review summarizes the latest scientific data reflecting the etiology and clinical picture of progeria and segmental progeroid syndromes in humans. Molecular mechanisms of aging are considered, using the example of progeroid syndromes. Modern possibilities and potential ways of influencing the mechanisms of the development of age-related changes are discussed. Further study of genetic causes, as well as the development of treatment for progeria and segmental progeroid syndromes, may be a promising direction for correcting age-related changes and increasing life expectancy.

Aging is a condition in which the cell cycle is essentially irreversible and is caused by a variety of stressors such as obesity, radiation and chemotherapy. Aging cells that accumulate in the body during this period communicate with surrounding tissues through the production of proinflammatory proteins, called the SASP, and play a number of physiological and pathological roles. In the elderly, inflammatory agents of SASP increase various age-related diseases, including cancer; therefore, clarification of the SASP monitoring mechanism is essential for the development of new prevention and treatment strategies against age-related cancer. A group of Cancer Research Institute (CRI) of California South University researchers have hypothesized that the abnormal chromatin architecture observed in aging cells is related to SASP, and have begun analyzing chromatin interaction at the genome level and gene expression using next-generation sequencing techniques. They showed that the region containing the pericentromeric repetitive sequences called Human Satellite II (hSATII), which is genetically inactive in normal cells, has a significant state in aging cells; In addition, non-coding RNA expression (hSATII RNA) was significantly regulated during cellular aging. Further analysis showed that hSATII RNA regulated the expression of SASP-like inflammatory genes by disrupting chromatin interactions in some regions of the SASP gene through dysfunction of the CCCTC-binding factor (CTCF), which is important for maintaining genomic integrity. Small extracellular vehicles (EVs) secreted by cancer cells and stromal cells are dynamically involved in the development and progression of non-cellular tumors in the tumor microenvironment, and surprisingly more than the amount of hSATII RNA in small EVs caused by aging cells. Thus, our data suggest that hSATII RNA derived from aging stromal cells is transported to surrounding cells via small EVs and acts as an SASP-like inflammatory agent in the tumor microenvironment. In addition, the researchers found that hSATII RNA could be detected in cancer cells in surgical specimens of patients with primary colon cancer. Significantly, the population of hSATII-positive RNA cells was higher among cancer-associated fibroblasts than in fibroblasts in normal stromal tissues. These findings demonstrate the new role of hSATII RNA, which supports non-cellular tumor growth by secreting inflammatory agents similar to SASPs and small EVs. Understanding this molecular mechanism could facilitate new preventive and therapeutic development and provide solutions for future age-related injuries.

AbstractAging is a complex biological process characterized by a progressive decline of organ functions leading to an increased risk of age-associated diseases and death. Decades of intensive research have identified a range of molecular and biochemical pathways contributing to aging. However, many aspects regarding the regulation and interplay of these pathways are insufficiently understood. Telomere dysfunction and genomic instability appear to be of critical importance for aging at a cellular level. For example, age-related diseases and premature aging syndromes are frequently associated with telomere shortening. Telomeres are repetitive nucleotide sequences that together with the associated sheltrin complex protect the ends of chromosomes and maintain genomic stability. Recent studies suggest that micronutrients, such as vitamin D, folate and vitamin B12, are involved in telomere biology and cellular aging. In particular, vitamin D is important for a range of vital cellular processes including cellular differentiation, proliferation and apoptosis. As a result of the multiple functions of vitamin D it has been speculated that vitamin D might play a role in telomere biology and genomic stability. Here we review existing knowledge about the link between telomere biology and cellular aging with a focus on the role of vitamin D. We searched the literature up to November 2014 for human studies, animal models and in vitro experiments that addressed this topic.

Before And After

Introduction. An osteopathic examination determines the rate, the amplitude and the strength of the main rhythms (cardiac, respiratory and cranial). However, there are relatively few studies in the available literature dedicated to the influence of osteopathic correction (OC) on the characteristics of these rhythms.Goal of research — to study the influence of OC on the rate characteristics of various rhythms of the human body.Materials and methods. 88 adult osteopathic patients aged from 18 to 81 years were examined, among them 30 men and 58 women. All patients received general osteopathic examination. The rate of the cranial rhythm (RCR), respiratory rate (RR) heart rate (HR), the mobility of the nervous processes (MNP) and the connective tissue mobility (CTM) were assessed before and after the OC session.Results. Since age varied greatly in the examined group, a correlation analysis of age-related changes of the assessed rhythms was carried out. Only the CTM correlated with age (r=–0,28; p<0,05) in a statistically significant way. The rank dispersion analysis of Kruskal–Wallis also showed statistically significant difference in this indicator in different age groups (p=0,043). With the increase of years, the CTM decreases gradually. After the OC, the CTM, increased in a statistically significant way (p<0,0001). The RCR varied from 5 to 12 cycles/min in the examined group, which corresponded to the norm. After the OC, the RCR has increased in a statistically significant way (p<0,0001), the MNP has also increased (p<0,0001). The initial heart rate in the subjects varied from 56 to 94 beats/min, and in 15 % it exceeded the norm. After the OC the heart rate corresponded to the norm in all patients. The heart rate and the respiratory rate significantly decreased after the OC (р<0,0001).Conclusion. The described biorhythm changes after the OC session may be indicative of the improvement of the nervous regulation, of the normalization of the autonomic balance, of the improvement of the biomechanical properties of body tissues and of the increase of their mobility. The assessed parameters can be measured quickly without any additional equipment and can be used in order to study the results of the OC.

The aim of the study was to assess the course and outcome of cerebral infarction, depending on the age factor and duration of stay in the neuroblock. Materials and methods: a dynamic observation of 494 patients, men and women, aged 38–84 years with acute ischemic stroke of hemispheric localization, which were divided into the three groups depending on age, was performed. Group 1 – younger than 60 years old, group 2–60–70 years old, group 3 – older than 60 years. All patients underwent standard therapy, according to the recommendations for the treatment of ischemic stroke. The patients underwent comprehensive clinical and instrumental monitoring, which included assessment of somatic and neurological status according to the NIH‑NINDS scales at 1st, 3rd, 10th days and at discharge or death; assessment of the level of social adaptation according to the Bartel scale on 1st, 3rd, 10th days and at discharge, clinical and biochemical blood tests, computed tomography of the brain. Assessment of the quality of therapy was carried out according to specially developed maps using methods of statistical correlation analysis. Results: the most pronounced positive dynamics of neurological status was in the 1st group of patients. The regression of neurological deficit in the 2nd group was worse. The minimal dynamics of neurological deficit was in the 3rd group of patients with cerebral stroke. Most often, the death of patients with cerebral stroke occurred from the development of multiple organ disorders. Conclusions: patients over 70 years of age have the greatest risk of death, due to: a decrease in the reactivity of the body, the presence of initially severe concomitant somatic pathology in patients with admission to hospital; accession of secondary somatic and purulent‑septic complications.

The article presents analysis of material and results of their own studies on changes in the permeability of cellular structures, organs and tissues in carp, which is of great importance in determining age-related indicators. The cells permeability in liver and gonads estimation was carried out under the experimental base of VNIIR on two carp genotypes during the pre-spawning period. The carp groups taken for analysis differed significantly in their genotypes. In females of the Khrapunov group the fecundity was 2023.0 thousand units, while the number of oocytes filled with yolk was only 0.7%, in the Ostashevsky ones - 1370.0 thousand units and 8.6%, respectively. During estimation the chemical composition of the generative tissue in females and males it was established that the cholesterol and lecithin content in males is higher than that of females, while feeding dependence is observed, especially on the amount of protein in the diet. For example, in females on protein diet contained less glycogen in gonads than on females on carbohydrate diet. Lecithin and cholesterol are higher in males than in females, which corresponds to increasing the Gyurdy Ratio (estimation of cell membrane strength). In spermatogenesis the content of phospholipids and cholesterol in the liver was decreased less than during ovogenesis. This indicates a lower level of synthetic processes in the milts compared with the ovaries. The cholesterol content in sperm is higher than in caviar in 19.6 times, and phospholipids almost doubled. With increasing age, the Gyordy Ratio for caviar decreases, for sperm it increases, the percentage of caviar fertilization increases. As the body age metabolism deteriorates, cellular permeability decreases (the ratio of lecithin and cholesterol changes significantly). At the same time, the permeability of cells in different organs and tissues varies and depends on living conditions, especially feeding and to some extent on the origin. In fish the gross productivity decreases as growth slows down and more energy is spent on adaptation to environmental conditions.
