Reduced levels of physical activity in people’s daily lives cause the development of metabolic syndromes or age-related disorders. Chronic inflammation is now understood to be an underlying pathological condition in which inflammatory cells such as neutrophils and monocyte/macrophages infiltrate into fat and other tissues and accumulate when people become obese due to overeating and/or physical inactivity. Pro-inflammatory mediators such as cytokines that are secreted in excess from inflammatory cells will not only lead to the development of arteriosclerosis when they chronically affect blood vessels but also bring tissue degeneration and/or dysfunction to various organs. Chronic inflammation is also involved in sarcopenia that brings hypofunction in the elderly, dementia, osteoporosis, or cancer and negatively affects many chronic diseases and people’s healthy life expectancy. In this paper, outlines of such studies are introduced in terms of homeostatic inflammation, which occurs chronically due to the innate immune system and its abnormalities, while focusing on the efficacy of exercise from aspects of immunology and oxidative stress. The preventative effects of functional food ingredients in combination with exercise are also introduced and described. The challenges and future directions in understanding the role of exercise in the control of chronic inflammation are discussed.

Modern concepts about the importance of subclinical inflammation in various age-associated pathology are described in the review. The term “inflammaging” (inflammation due to aging) refers to the special role of inflammation in the aging processes. This type of inflammation is low-grade, controlled, asymptomatic, chronic and systemic. Inflammaging determines the rate of aging and life expectancy. The balance of pro-inflammatory and anti-inflammatory cytokines plays a significant role in aging processes. The increased levels of pro-inflammatory cytokines such as interleukin-6 and tumor necrosis factor-α in the elderly are associated with different diseases, disability and mortality. Interleukin-6 is a multifunctional cytokine involved in the regulation of acute phase response and other immunological reactions, in the hematopoiesis and in chronic inflammation. This cytokine is important in the pathogenesis of chronic inflammation diseases, as well as different oncological disorders. Interleukin-6 is often called the “cytokine of gerontologists”, since it is one of the main signaling pathways associated with aging and age-related diseases. This cytokine also plays an important role in the pathogenesis of atherosclerosis, coronary artery disease, chronic heart failure and increases the risk of death from cardiovascular diseases and overall mortality. Interleukin-6 is a key proinflammatory cytokine responsible for the “metabolic inflammation”, obesity, insulin resistance and diabetes mellitus. This cytokine has a significant impact on the development of sarcopenia and frailty. The serum levels of interleukin-6 negatively correlate with muscle mass and skeletal muscle function in the elderly, so it is considered as a biomarker of sarcopenia and functional decline. Interleukin-6 may contribute to the development of osteoporosis by stimulating osteoclastogenesis and bone resorption. The modern data indicate the diverse effects of interleukin-6 and confirm the significant role of this cytokine in aging and in different age-associated pathology.

Discrepancies in lifespan and healthy-life span are predisposing populations to an increasing burden of age-related disease. Accumulating evidence implicates aging of the immune system, termed immunosenescence, in the pathogenesis of multiple age-related diseases. Moreover, immune dysregulation in the elderly increases vulnerability to infection and dampens pathogen-specific immune responses following vaccination. The health challenges manifesting from these age related deficits have been dramatically exemplified by the current SARS-CoV-2 pandemic. Approaches to either attenuate or reverse functional markers of immunosenescence are therefore urgently needed. Recent evidence suggests systemic immunomodulation via non-specific vaccination with live-attenuated vaccines may be a promising avenue to at least reduce aged population vulnerability to viral infection. This short review describes current understanding of immunosenescence, the historical and mechanistic basis of vaccine-mediated immunomodulation, and the outstanding questions and challenges required for broad adoption.

Osteoporosis (OP) and vascular calcification (VC) represent relevant health problems that frequently coexist in the elderly population. Traditionally, they have been considered independent processes, and mainly age-related. However, an increasing number of studies have reported their possible direct correlation, commonly defined as “bone-vascular crosstalk”. Vitamin K2 (VitK2), a family of several natural isoforms also known as menaquinones (MK), has recently received particular attention for its role in maintaining calcium homeostasis. In particular, VitK2 deficiency seems to be responsible of the so-called “calcium paradox” phenomenon, characterized by low calcium deposition in the bone and its accumulation in the vessel wall. Since these events may have important clinical consequences, and the role of VitK2 in bone-vascular crosstalk has only partially been explained, this review focuses on its effects on the bone and vascular system by providing a more recent literature update. Overall, the findings reported here propose the VitK2 family as natural bioactive molecules that could be able to play an important role in the prevention of bone loss and vascular calcification, thus encouraging further in-depth studies to achieve its use as a dietary food supplement.

Introduction: GDF 11 is a member of the transforming growth factor β superfamily. Loss of GDF11 occurs with aging and declining levels correlate with several detrimental age-associated phenotypes in both peripheral tissues and brain. Restoration of GDF11 enhances neurogenesis and cognitive function in aged mice. Brain expression of GDF11 has not been investigated after stroke. Stroke differentially affects the elderly. In this work we examined the role of GDF11 in aging, stroke and its potential utility as a neuroprotective agent. Methods: Male C57/BL6NCrl young (2-3 months) and aged (19-21) mice were used. Brain GDF11 expression was evaluated in young and aged mice by western blot. Focal ischemia was induced with a transient middle cerebral artery occlusion (MCAO). Mice were randomly assigned into two groups and were subjected to 90 min MCAO. Group 1 received vehicle (phosphate buffered saline) and group 2 was administered rGDF11 (100 ug/kg., ip) at the onset of ischemia. In additional experiments, the efficacy of delayed treatment (3 h after ischemia) with rGDF11 was tested. These mice were subjected to a 60 min MCAO. Mice were euthanized after 24 hours and 7 days respectively and brains were harvested to estimate infarct area. Results: A significant decrease in brain GDF11 levels was observed in aged mice as compared to young (p<0.05). Additionally, a significant decline in brain GDF11 expression was observed after stroke at 24 hours vs. sham groups (p<0.05). A significant decrease in cortical and hemispheric infarct area was observed in the rGDF11 group (cortical 48.73±1.05; hemisphere 49.68±3.58) as compared to vehicle group (60.54±4.88; 61.35±6.03), when GDF was administered at the time of ischemia. Delayed treatment with rGDF11 also reduced infarct at 7 days. Conclusions: Brain GDF11 levels decline with age and after stroke. Supplementation with rGDF11 ameliorates stroke induced injury in young mice at 24h and 7 days. These finding suggest potential role of GDF11 in age and stroke. Restoration of age-related loss of GDF may be a viable therapy for stroke.

Decreased immune functions have been suggested as a cause for the increased incidence of autoimmunity, malignancy, and infection in the elderly population. To assess the possible role of changes in macrophage function in the aging process we studied the Fc receptor- mediated clearance of IgG-coated erythrocytes in 56 healthy normal volunteers by following the removal of radiolabeled autologous erythrocytes. An age-related decrease in Fc-mediated clearance rates in both female and male subjects was found, which suggests a physiological decline of this macrophage function in older individuals.

Высокий риск когнитивных расстройств у лиц пожилого и старческого возраста заставляет, с одной стороны, искать их причины, с другой - возможности профилактики. В связи с этим в последние годы получило распространение понятие когнитивного резерва, подразумевающего совокупность количественных параметров головного мозга и его способности сохранять высокую функциональную активность в процессе старения и на фоне связанной с возрастом патологии головного мозга. Представленный в статье материал на основе обзора научной литературы освещает два основных момента, касающихся возможности сохранения когнитивного резерва, - гендерный и образовательный факторы. Указывается на разные возможности женщин и мужчин, связанные со структурными и функциональными особенностями ЦНС у представителей разного пола, и на особую роль поддерживаемого в течение всей жизни образовательного процесса. Обозначена авторская позиция о необходимости разделения понятий образования и образованности, то есть уровня общей культуры и создания удобного инструмента для определения последнего. Это, в свою очередь, помогло бы в разработке модели когнитивного резерва, нацеленной на предотвращение трансформации физиологического когнитивного старения в патологическое. The high risk of cognitive disorders in the elderly and senile age makes, on the one hand, to look for their causes, on the other - the possibility of prevention. In this regard, in recent years, the concept of cognitive reserve has become widespread, implying a set of quantitative parameters of the brain and its ability to maintain high functional activity in the process of aging and against the background of age-related brain pathology. The material presented in the article on the basis of the review of scientific literature highlights two main points concerning the possibility of preserving the cognitive reserve-gender and educational factors. It is pointed to the different opportunities of women and men associated with the structural and functional characteristics of the Central nervous system in representatives of different sexes and the special role of the educational process supported throughout life. The author’s position on the need to separate the concepts of education and the level of General culture, and the creation of a convenient tool for determining the latter is indicated. This, in turn, would help in the development of a cognitive reserve model aimed at preventing the transformation of physiological cognitive aging into pathological aging.

Choroidal neovascularization (CNV) is a common and severe complication in heterogeneous diseases affecting the posterior segment of the eye, the most frequent being represented by age-related macular degeneration. Although the term may suggest just a vascular pathological condition, CNV is more properly definable as an aberrant tissue invasion of endothelial and inflammatory cells, in which both angiogenesis and inflammation are involved. Experimental and clinical evidences show that vascular endothelial growth factor is a key signal in promoting angiogenesis. However, many other molecules, distinctive of the inflammatory response, act as neovascular activators in CNV. These include fibroblast growth factor, transforming growth factor, tumor necrosis factor, interleukins, and complement. This paper reviews the role of inflammatory mediators and angiogenic factors in the development of CNV, proposing pathogenetic assumptions of mutual interaction. As an extension of this concept, new therapeutic approaches geared to have an effect on both the vascular and the extravascular components of CNV are discussed.

Despite an increase in life expectancy that indicates positive human development, a new challenge is arising. Aging is positively associated with biological and cognitive degeneration, for instance cognitive decline, psychological impairment, and physical frailty. The elderly population is prone to oxidative stress due to the inefficiency of their endogenous antioxidant systems. As many studies showed an inverse relationship between carotenoids and age-related diseases (ARD) by reducing oxidative stress through interrupting the propagation of free radicals, carotenoid has been foreseen as a potential intervention for age-associated pathologies. Therefore, the role of carotenoids that counteract oxidative stress and promote healthy aging is worthy of further discussion. In this review, we discussed the underlying mechanisms of carotenoids involved in the prevention of ARD. Collectively, understanding the role of carotenoids in ARD would provide insights into a potential intervention that may affect the aging process, and subsequently promote healthy longevity.

Children are more susceptible to various infections because of underdeveloped immune system as compared to adults. Strengthening the immune system is a natural way to help the body fight against the disease-causing pathogens and immunomodulators can play a major role in this context. Various Ayurveda classics and studies published in journals related to Ayurveda drugs for improving immunity are reviewed and analysed. In Ayurveda, the objective of immune enhancement is achieved through the use of the Amalakyadi Rasayana (an Immunomodulators), as it increases longevity of life, memory, intellect, luxture, complexion, voice, strength of the body functions, strength of all senses and provides the resistance to disease, improves glow and power. Analysis of classical references and various experimental studies show that Amalakyadi Rasayana posse immuno-modulatory, Antioxidant, Anti-inflammatory, Antimicrobial, Anthelmintic activity. Present paper is a review to update knowledge on pharmacological properties, therapeutic actions and possible mode of action of the selected formulation, Amalakyadi rasayana from Yogaratnakara (Rasayanadhikara/17) to enhance the immunity in children. Rasayana is an important part of Ayurvedic therapeutics used to improve the quality of life by strengthening the tissue quality and by reducing the age-related tissue degeneration. This study reveals that Amalakyadi Rasayana have potential to improve or strengthen the immune system in children and thereby can lower down the morbidity rate in children.
