Frailty represents diminished reserve across multiple physiologic systems, accompanied by increased vulnerability to stressors and increased morbidity and mortality. With population aging, strategies to prevent and manage frailty are priorities in clinical medicine and public health. Current evidence-based approaches to frailty management are multimodal in nature. Yoga, an increasingly popular and highly adaptable mind-body practice, is multi-component, incorporating physical postures, breathing practices, meditation, and other elements, and may be a strategy for frailty management. Here, we summarize the evidence linking yoga practice to mitigation of age-related degradation across multiple physiologic systems, including cardiovascular, pulmonary, musculoskeletal, and nervous systems. We discuss putative mechanisms of action including modulation of the hypothalamic–pituitary–adrenal axis. Finally, we consider implications for clinical practice and future research.

Neurofeedback training involves presenting an individual with a representation of their brain activity and instructing them to alter the activity using the feedback. One potential application of neurofeedback is for patients to alter neural activity to improve function. For example, there is evidence that greater laterality of movement-related activity is associated with better motor outcomes after stroke; so using neurofeedback to increase laterality may provide a novel route for improving outcomes. However, we must demonstrate that individuals can control relevant neurofeedback signals. Here, we performed two proof-of-concept studies, one in younger (median age: 26 years) and one in older healthy volunteers (median age: 67.5 years). The purpose was to determine if participants could manipulate laterality of activity between the motor cortices using real-time fMRI neurofeedback while performing simple hand movements. The younger cohort trained using their left and right hand, the older group trained using their left hand only. In both studies participants in a neurofeedback group were able to achieve more lateralized activity than those in a sham group (younger adults: F(1,23) = 4.37, p < 0.05; older adults: F(1,15) = 9.08, p < 0.01). Moreover, the younger cohort was able to maintain the lateralized activity for right hand movements once neurofeedback was removed. The older cohort did not maintain lateralized activity upon feedback removal, with the limitation being that they did not train with their right hand. The results provide evidence that neurofeedback can be used with executed movements to promote lateralized brain activity and thus is amenable for testing as a therapeutic intervention for patients following stroke.

Objectives This study aims to identify and explain the continuum in which older people in Singapore participate in community and social life, highlighting the influence of culture and policy context on social participation. Methods Using an ethnographic approach in a neighbourhood (n = 109), we conducted focus groups with older adults of different ethnicities, exploring experiences of social participation. Next, participants took 50 photographs relating to ‘lives of elders’, showcasing the socio-ecological context that influenced social participation. Lastly, go-along interviews were conducted in various precincts with community leaders. Results A continuum of social participation emerged among older adults, ranging from (1) marginalization and exclusion, to (2) ‘comfort-zoning’ alone (3) seeking consistent social interactions, (4) expansion of social network, and (5) giving back to society. Seeking consistent social interactions was shaped by a preference for cultural grouping and ethnic values, but also a desire for emotional safety. Attitudes about expanding one's social network depended on the psychosocial adjustment of the older person to the prospect of gossip and ‘trouble’ of managing social relations. Despite the societal desirability of an active ageing lifestyle, cultural scripts emphasizing family meant older adults organized participation in social and community life, around family responsibilities. Institutionalizing family reliance in Singapore's welfare approach penalized lower-income older adults with little family support from accessing subsidies, and left some living on the margins. Discussion To promote inclusiveness, ageing programs should address preferences for social participation, overcoming barriers at the individual, ethnic culture and policy level.

The world's weather is constantly shifting and increasingly unpredictable. Climate change was also shown to influence human health and both soil and gut microbiome. These changes may also affect the human aging process, which is connected to multidimensional aspects ranging from health, economy, and psychology. As a result, the purpose of this review is to examine the relationship between aging, gut microbiota, and climate change. This discussion aims to increase awareness of the inevitable change in aging physiology and gut microbiota composition that is caused by climate change by tying together the environmental and clinical health elements. This review will also support the evidence for the link between environmental problems and public health problems. The main findings of this review found that human aging and gut microbiota had a bidirectional relationship. The change in one matter influences the other, which may be instigated by climate change. Moreover, climate change also influences the soil microbiome, which is indirectly related to the quality of the crops that will further act as nutritional factors that shift the composition of human gut microbiota. Various modulation mechanisms of gut microbiota in aging domains were also explored. The review was concluded by proposing a model and underlining some implications that need to be further addressed.

- Abstract
Introduction: The maximum oxygen uptake (V˙O2max), the maximum rate of oxygen that can be sustained before the onset of blood lactate accumulation, and the metabolic cost of locomotion are the main physiological factors associated with long-distance running performance. The latter is known as the running economy. Generally, runners reach peak performance in long races between 25 and 30 years of age, with a progressive decline occurring thereafter. However, it is not known whether the running economy is affected or how it is affected by aging. Aim: To investigate the effect of age and years of running experience on the running economy of amateur long-distance runners aged 20-80 years. Methods: Sixty-nine recreational long-distance runners, divided into five age groups according to decade of life, participated in this study: Group 1 (n= 9) 27.2 ± 1.3 years, Group 2 (n= 18) 35.9 ± 2.2 years, Group 3 (n= 17) 43.4 ± 2.8 years, Group 4 (n= 17) 53.0 ± 2.3 years, and Group 5 (n= 8) 65.5 ± 2.9 years. For running economy assessment, oxygen cost (OC) and energy cost (EC) were measured. Furthermore, the participants were interviewed on their running experience. Results: For EC, the two independent variables composing the regression model were age (ß = 0.703, t= 5.443, p < 0.001) and running experience (ß = -0.230, t = -1.785, p= 0.07), and 34% of the energy cost variation can be explained by these two factors. EC and OC were compared among the groups. There were no significant differences between Groups 1 and 2 (p= 0.999), Groups 1 and 3 (p= 1.000), and Groups 1 and 4 (p= 0.528). However, Group 5 had a significantly higher energy cost than Group 1 (p < 0.001), Group 2 (p < 0.001), Group 3 (p < 0.001) and Group 4 (p < 0.001). Conclusion: The number of years of running experience has a positive effect on running economy, but it is insufficient to overcome the negative effect of the aging process. Furthermore, running economy was significantly worse in participants aged ≥60 years

- Abstract
Currently, there is little information to indicate whether plant cell division and development is the collective effect of individual cell programming (cell-based) or is determined by organ-wide growth (organismal). Modulation of cell division does not confirm cell autonomous programming of cell expansion; instead, final cell size seems to be determined by the balance between cells formed and subsequent tissue growth. Control of growth in regions of the plant therefore has great importance in determining cell, organ and plant development. Here, we question the view that formation of new cells and their programmed expansion is the driving force of growth. We believe there is evidence that division does not drive, but requires, cell growth and a similar requirement for growth is detected in the modified cycle termed endoreduplication.

The exponential aging of population all across the world has its own significance and implications as it pertains to older adults. The incidence of comorbidities and disability is high in this age group, resulting in functional decline as a result of physiologic, pathophysiologic, environmental, and socioeconomic conditions. Functional decline leads to decreased cognition, mobility, and activities of daily living. This chapter discusses aging demographics, normal aging physiology, mechanisms of aging, implications of multimorbidity, geriatric syndromes including frailty, disability, emerging complex care team models, the role of physical activity in the prevention and treatment of common age-related conditions, and the role of the physiatrist in geriatric care models.

The exploration of noncoding RNAs, especially microRNAs (miRNAs), in the past few decades redrafted the central dogma of molecular biology and our understanding of gene regulation. These miRNAs are small (∼21–25 nt), endogenous, evolutionarily conserved, noncoding, single-stranded RNA molecules that regulate gene expression by posttranscriptional silencing. They play a vital role in all segments of life, from embryo development to aging, physiology to pathology, and in all forms of life, from algae to angiosperms and protozoa to mammals. In this chapter, we discuss the techniques employed to study the biology of miRNAs, screening techniques, and their potential applications in various fields; in short, miRNAs are tiny but mighty.

- Abstract
The author is ready to assert that practically none of the readers of this book will ever happen to deal with large doses of radiation. But the author, without a shadow of a doubt, claims that any readers of this book, regardless of gender, age, financial situation, type of professional activity, and habits, are actually exposed to low doses of radiation throughout their life. This book is devoted to the effect of small doses on the body. To understand the basic effects of radiation on humans, the book contains the necessary information from an atomic, molecular and nuclear physics, as well as from biochemistry and biology. Special attention is paid to the issues that are either not considered or discussed very briefly in existing literature. Examples include the ionization of inner atomic shells that play an essential role in radiological processes, and the questions of transformation of the energy of ionizing radiation in matter. The benefits of ionizing radiation to mankind is reflected in a wide range of radiation technologies used in science, industry, agriculture, culture, art, forensics, and, what is the most important application, medicine. Radiation: Fundamentals, Applications, Risks and Safety provides information on the use of radiation in modern life, its usefulness and indispensability. Experiments on the effects of small doses on bacteria, fungi, algae, insects, plants and animals are described. Human medical experiments are inhuman and ethically flawed. However, during the familiarity of mankind with ionizing radiation, a large number of population groups were subject to accumulation, exposed to radiation at doses of small but exceeding the natural background radiation. This book analyzes existing, real-life radiation results from survivors of Hiroshima and Nagasaki, Chernobyl and Fukushima, and examines studies of radiation effect on patients, radiologists, crews of long-distant flights and astronauts, on miners of uranium copies, on workers of nuclear industry and on militaries, exposed to ionizing radiation on a professional basis, and on the population of the various countries receiving environmental exposure. The author hopes that this book can mitigate the impact of radiation phobia, which prevails in the public consciousness over the last half century. - Explores the science of radiation and the effects of radiation technologies and biological processes - Analyzes the elementary processes of ionization and excitation - Summarizes information about inner shells ionization and its impact on matter and biological structures - Discusses quantum concepts in biology and clarifies the importance of epigenetics in radiological processes - Includes case studies focusing on humans irradiated by low doses of radiation and its effects

- Abstract
The volume of elderly patients requiring anesthesia and surgery is growing rapidly. Thirty-five percent of surgeries are performed on patients older than 65 years, and in general, these patients have higher morbidity and mortality rates after anesthesia compared with their younger counterparts. One of the major challenges of treating elderly patients is the heterogeneity of the geriatric population—and the need to individualize care for each patient to provide the best outcome.

- Abstract
This issue will focus on the most common reproductive endocrine conditions encountered by healthcare providers. This series is timely and will be of interest to readers as there are many recent updates to the recommendations for appropriate evaluation and treatment of several reproductive conditions. Each chapter will address specific anatomic and hormonal conditions and will examine reproductive function from puberty to menopause. A thorough summary of abnormal uterine bleeding including recent 2012 updates for evaluation and management will be emphasized. Individual chapters on anatomic causes of bleeding, such as uterine fibroids and endometriosis, will be included with a focus on new treatment options. Polycystic ovarian syndrome (PCOS), a common hormonal cause of irregular bleeding and infertility, will also be reviewed. Recent studies provide insight into new fertility treatments for patients with PCOS including the use of aromatase inhibitors for ovulation induction. Other fertility related chapters include the evaluation of the infertile woman, ovulation induction, recurrent pregnancy loss, and age-related infertility. Finally, a transition to premature ovarian insufficiency and menopause will be provided. The Women's Health Initiative publication in 2002 reported an association between hormone replacement therapy and breast cancer. There are several updates since this controversial publication and recent literature will be summarized. Attention will focus on appropriate evaluation and management of these common reproductive endocrine topics reviewing recent recommendations on best practices for clinicians.

- Abstract
Fundamentals of Radiation and Chemical Safety covers the effects and mechanisms involved in radiation and chemical exposure on humans. The mechanisms and effects of these damaging factors have many aspects in common, as do their research methodology and the methods used for data processing. In many cases of these types of exposures the same final effect can also be noted: Cancer. Low doses of radiation and small doses of chemical exposure are continuously active and they could influence the entire population. The analysis of these two main source hazards on the lives of the human population is covered here for the first time in a single volume determining and demonstrating their common basis. Fundamentals of Radiation and Chemical Safety includes the necessary knowledge from nuclear physics, chemistry and biology, as well the methods of processing the experimental results. This title focuses on the effects of low radiation dosage and chemical hormesis as well as the hazards associated with, and safety precautions in radiation and chemicals, rather than the more commonly noted safety issues high level emergencies and disasters of this type. - Brings together, for the first time, the problems of radiation and chemical safety on a common biophysical basis. - Relates hazards caused by ionizing radiation and chemicals and discusses the common effective mechanisms - Outlines common methodology and data processing between radiation and regular chemical hazards - Concerns primarily with low levels of radiation and chemical exposure

- Abstract
Respiration is one of the most basic motor activities crucial for survival of the individual. It is under total control of the central nervous system, which adjusts respiratory depth and frequency depending on the circumstances the individual finds itself. For this reason this volume not only reviews the basic control systems of respiration, located in the caudal brainstem, but also the higher brain regions, that change depth and frequency of respiration. Scientific knowledge of these systems is crucial for understanding the problems in the many patients suffering from respiratory failure. - This well-established international series examines major areas of basic and clinical research within neuroscience, as well as emerging subfields.

- Abstract
Numerous aspects of mammalian physiology exhibit cyclic daily patterns known as circadian rhythms. However, studies in aged humans and animals indicate that these physiological rhythms are not consistent throughout the life span. The simultaneous development of disrupted circadian rhythms and age-related impairments suggests a shared mechanism, which may be amenable to therapeutic intervention. Recently, the endocannabinoid system has emerged as a complex signaling network, which regulates numerous aspects of circadian physiology relevant to the neurobiology of aging. Agonists of cannabinoid receptor-1 (CB1) have consistently been shown to decrease neuronal activity, core body temperature, locomotion, and cognitive function. Paradoxically, several lines of evidence now suggest that very low doses of cannabinoids are beneficial in advanced age. One potential explanation for this phenomenon is that these drugs exhibit hormesis-a biphasic dose-response wherein low doses produce the opposite effects of higher doses. Therefore, it is important to determine the dose-, age-, and time-dependent effects of these substances on the regulation of circadian rhythms and other processes dysregulated in aging. This review highlights 3 fields-biological aging, circadian rhythms, and endocannabinoid signaling-to critically assess the therapeutic potential of endocannabinoid modulation in aged individuals. If the hormetic properties of exogenous cannabinoids are confirmed, we conclude that precise administration of these compounds may bidirectionally entrain central and peripheral circadian clocks and benefit multiple aspects of aging physiology., (Copyright © 2019 Elsevier Inc.

- Abstract
Because superoxide is involved in various physiological processes, many efforts have been made to improve its accurate quantification. We optimized and validated a superoxide-specific and -sensitive detection method. The protocol is based on fluorescence detection of the superoxide-specific hydroethidine (HE) oxidation product, 2-hydroxyethidium. We established a method for the quantification of superoxide production in isolated mitochondria without the need for acetone extraction and purification chromatography as described in previous studies., (Copyright © 2012 Elsevier Inc.
