  8. On Population Kinetics of an Aging Society: Aging and Scurvy

    CERN Document Server

    Ely, J T A

    2006-01-01

    Evidence from skeletal remains and pictorial records for the past several millennia established that humans have had a very inadequate ascorbic acid intake and commonly exhibited signs of frank scurvy, as well as the invisible signs of subclinical scurvy (absence of AA in scorbutic urine is universal). They suffered scurvy's mortality, being a major cause of death especially in times of stress due to dietary fluctuations, climate, migrations, voyages, battles, etc. Rapid aging and death by acute scurvy, and infectious and degenerative diseases related to chronic scurvy added to the toll. In this era, the loss of function and changes in appearance that we see in humans in the second 50 years of life are theoretically simple to avoid. However, this is very rare because there is almost no one who does not eat the refined diet of the affluent societies. We present here an overview of a vast array of evidence on the connections between aging and scurvy.

  9. Older adult education in Lithuanian ageing society

    2016-01-01

    Full Text Available The article analyzes the phenomenon of the demographic ageing of the population and educational opportunities for older adults in Lithuania. Ageing population is a natural outcome of demographic evolution of society. However, a growing number of older people in Lithuania as well as in other European countries requires continuous revision of societal resources in social security, economics, education, health care areas and their adjustment to the new demands. Though current discussion in Lithuania highlights the inclusion of older adults into active social life through educational activities, the studies in diverse areas show that a small number of older people take part in lifelong learning. For this reason and in the attempt to make older people feel satisfaction with life it is necessary to encourage their activity, to promote their social roles, to give them opportunities to take up voluntary tasks, educational and cultural functions and study new subjects.

    Full Text Available Drawing on the interplay between gender, aging, and sexuality, the aim of this article is twofold: (1 to show how Brazilian gerontologists treat gender differences and sexual activity in old age; (2 to analyze the  ways  discourses regarding the aging body and sexuality are perceived and evaluated by older women and men . I argue that  attempts of gerontologists’ to eroticize old age have to contend with the widespread notion that the desire for sex is inevitably lost with age. Thus, in the retiree associations that were studied, men had a tendency to assume they are not ‘old’ because their erectile function was still in good condition, and divorced or widowed women, in senior citizen associations, tend to regard themselves as happy due to having freed themselves from the sexual obligations imposed by marriage. In both cases, the dominant belief that there is a loss of sexual desire in old age was reproduced.

    Besides dementia, depressive disorders belong to the most common mental disorders in the elderly. Along with the demographic change and the associated increasing proportion of older people aged 65 and more they become a central and urgent challenge. Depressive disorders in old age are treatable, although they involve special features when compared to younger adults. Guidelines are considered to be of great importance in the optimization of treatments. But how will the treatment of depressive disorders in the elderly displayed in the current guidelines? A systematic search for treatment recommendations in current evidence- and consensus-based guidelines regarding psychotherapeutic and psychosocial treatment approaches indicates that this highly relevant patient group has been strongly neglected so far.

    Recent data show that as populations age, the number of people affected by neurodegenerative dementia is growing at an epidemic pace in various regions of the world. This cross-cultural study examined the relationships among age, gender, ethnicity, religion, and education as well as the attitudes and perceptions related to ageing and dementia. A random sample of 980 participants was selected to represent the multicultural population of Singapore. Data were collected using standardised questionnaires through online portals and by conducting interviews. These data were ultimately analysed by comparing percentage responses and correlation coefficients and by conducting a multiple regression analysis. The results indicate that the perceptions and attitudes of individuals toward ageing and dementia differ among different age groups. Moreover, the level of education attained was significantly correlated with understanding dementia; regardless of education level, Christians had the most positive mindset toward dementia, although most religious individuals did not believe in divine healing. In this study, it was determined that attitudes and perceptions about ageing and dementia are influenced by multiple factors, such as education, age, and religion, and that it is imperative that younger generations develop coping strategies, including healthy lifestyles and social and/or religious communities to provide quality care to the elderly, in general, and to dementia patients, in particular.

  15. Economic and social implications of aging societies.

    2014-10-31

    The challenge of global population aging has been brought into sharper focus by the financial crisis of 2008. In particular, growing national debt has drawn government attention to two apparently conflicting priorities: the need to sustain public spending on pensions and health care versus the need to reduce budget deficits. A number of countries are consequently reconsidering their pension and health care provisions, which account for up to 40% of all government spending in advanced economies. Yet population aging is a global phenomenon that will continue to affect all regions of the world. By 2050 there will be the same number of old as young in the world, with 2 billion people aged 60 or over and another 2 billion under age 15, each group accounting for 21% of the world's population.

    The number of alpine accidents has markedly increased among elderly trekkers in an aging society, Japan. We evaluated the physical condition of 176 trekkers by interview and physical examination on a popular middle altitude mountain. Heart rate, noninvasive blood pressure and arterial oxygen saturation (SpO2) were measured using a portable life monitor. It was revealed that more than 70% of the trekkers were over 50. Seventy-five percent of trekkers over 70 had some pre-existing medical problems. Systolic and diastolic blood pressure before the start of trekking, increased with age. However, such age-dependent differences were not apparent at the summit hut. SpO2 values decreased slightly but significantly with age. In conclusion, many elderly people enjoy nonchallenging middle altitude trekking in an aging society. Alpine accidents caused by health problems tend to arise more frequently in this population. Alpine rescue teams should be well-prepared for the alpine accidents of elderly trekkers.

  19. The Issue of Nutrition in an Aging Society.

    2015-01-01

    Viewed from a global perspective, Japan is often considered a country where the progression towards a low birthrate and longevity has been prominent. In 2007, the ratio of the aged population reached 21.5%, propelling Japan into the classification of a super aging society. The long-term care insurance system in Japan was initiated in the year 2000, as a general long-term care service system for the whole society, covering the nutrition, medical care, and welfare fields. The goal of nutrition in an aged society is the extension of healthy life expectancy. The ratio of elderly citizens with malnutrition is high. Due to the loss of teeth, and a decrease in digestive and physical functions, there is often a decrease in appetite, and the inability to obtain enough nutrition for physical homeostasis is related to such conditions as frailty and the partial loss of physical functions due to sarcopenia, as well as a decrease in the quality of life (QOL). The elderly can easily fall into a state of protein and energy malnutrition (PEM), due to a variety of causes. Accordingly, it is important to adopt an appropriate approach that ensures a correct understanding of the causes of malnutrition and the special characteristics of malnutrition in the elderly.

    Atlases are collections of illustrated data, often maps, which give an overview - as well as some details - of one or several topic areas. We noted that this description serves well especially for traditional paper and digital atlases. However, in our today's world of entertainment it might give a somewhat dated impression. For the topic area 'Ageing Society' we aim to visualise age related data in an interactive digital way that supports not only the content but also engages the users, offers opportunities for different stakeholders and levels of interest, and is able to accommodate a range of data as well as future updates. A set of guiding principles for the development process addresses these challenges. First implementations show that following the principles is feasible but expensive in terms of time and attention to detail needed. For each selected topic, a story guides the users through the data and highlights interesting aspects. The user can interrupt the story at any time and explore the data further through interacting with the detailed data representations, and switch back to the story when needed. This allows different levels of access which in combination with the specifically designed navigation concept as well as through the adherence to user aware design principles are very promising for the future developments of the Atlas of the Ageing Society and potentially other atlas products.

    Understanding the impact of cohort values is important in trying to project future aging service needs. The cultural characteristics of cohorts yet to reach the age of 65 are compared with those already "old," with specific focus on the Baby Boomers. Aging policies (and available services) reflect the cultural notions of age and aging held as normative during the historical era in which they are enacted. Previous research into lifestyle preferences, consumer practices, and key characteristics is drawn upon to investigate the values of Baby Boomers in light of their projected needs for eldercare services. Cohort research and generational marketing practices offer a promising foundation for exploring how best to develop, target, and deliver aging services that most effectively utilize our social resources.

    Full Text Available The demographic changes are of great importance for all European societies. Their impact and effects have multiple, deep facets. Each European healthcare and welfare system will be facing considerable changes in the new demographic context. The hospital sector plays an important role in each health system. This paper focuses on the impact of the demographic changes on hospitals, presents and analyzes statistical data for the German hospitals sector in order to underline the importance of the older age groups for the number of the hospital inpatient cases, the provided range of medical services and disciplines and for the hospital disease costs. The paper also reveals main findings from 30 interviews conducted in 2010 with German health experts (from hospitals, health insurance companies, universities, institutes and regional healthcare policy makers that accepted to answer questions referring to the demographic impact on the German healthcare system and hospital sector. The results of the interviews show that hospitals will have to act and react to the demographic changes. German hospitals might play different roles in the healthcare service provision for older people when engaging in new models of integrated care that will have to be developed. Processes, structures, human resources expertise, hospital service provision and medical departments will undergo major changes in response to the demographic challenges. Networks, centres of excellence for older persons and integrated care will probably be indispensable structures of the German healthcare system in the future. Strategic partnerships with pre- and post-hospital healthcare service providers are considered to be top priorities for German hospitals when facing the demographic challenge. Central case management and process optimization can be essential factors of success in the hospital care of the older, multimorbid patients. Acute geriatric medicine will be a main quality feature for the

    Main challenges that may appear in our country along next decade related with the aging process are discussed. First of these challenges must take into account demography changes. Absolute number and. rates of elderly people increases permanently and it will be so in the next future. To assume the UN slogan "active aging" could be a positive attitude, and in this way both, each individual and social collectives, must be involved. In relation with health challenges, chronic disease and disability are the two most important problems. Prevention and permanent searching attitude of efficient political health answers are two essential pillars. Challenges on the social field must be focussed on ageism. The main objective must be to fight against any form of age discrimination (ageism). Beside that educational policies oriented over professionals and citizens. Last group of challenges concerns to managers and politicians and must be focussed on the look for resources and educational promotion.

    2015-01-01

    While it is anticipated that healthcare systems around the world will continue to rely heavily on family members and friends to provide unpaid care especially to meet the needs of our aging population, current assumptions and issues around caregivers need to be challenged and addressed if we are to expect their future support. This paper builds on Williams et al's assertion that many current assumptions and issues around caregivers need to be challenged and addressed if we are to expect their future support. Indeed, with the pool of available caregivers expected to actually shrink in the future, this paper therefore examines four key policy issues in greater depth that we can address to enable individuals to age in place and others to maintain and take on caregiving roles. Through the establishment of policies that support robust and longterm capacity planning; make clear what care recipients and caregivers can expect to receive in the form of government supports; appreciate the increasing diversity that is occurring among those taking on caregiving roles and those requiring care; and recognize the need to invest in strategies that combat social isolation, we may not only improve our future health and well-being but ensure we are also enabled to care for ourselves as we age.

Improved public health measures extend life expectancy at the relative expense of increased prevalence of currently incurable conditions such as dementia and Parkinson's disease. In this article we discuss how these demographic changes will impact and suggest possible means of coping with the altered epidemiology of disease and disability. Malaysia will need to swiftly develop sufficient expertise in acute Geriatric Medicine, rehabilitation of older people; the management of long-term conditions in older people with multiple complex problems within Primary Care; as well as an infrastructure for home and institutional care.

  13. Understanding generations: political economy and culture in an ageing society.

    Science.gov (United States)

    Vincent, John A

    2005-12-01

    Sociological understanding of generations can be enhanced by avoiding defining them rigidly as chronological cohorts but rather linking people's accounts of their generational experience with an historically informed political economy. It then becomes possible, for example, to understand the complexity of generational politics. This paper uses data on the 'War Generation' taken from the Exeter Politics of Old Age project to link an empirically based political economy of generational inequality with a cultural sociology of generations. The 'War Generation' recognizes itself and is referred to by others in terms of a common identity. It is also an historical generation; its values, attitudes and, above all, sense of national solidarity and mutual obligation were forged in the direct experience of war. But it is also divided by divergent economic interests in property and pension rights based on the historical experience of the life course by successive groups and this segmentation can be observed in political action. The political culture of the War Generation manifests both continuity and change. Understanding these dynamics requires listening to people constructing their worlds, understanding their full range of historical experiences, and analysing the conditions for their conflicts and their cohesion.

    Barrett, Anne E; Pai, Manacy; Redmond, Rebecca

    2012-12-01

    Although studies document the health-enhancing effects of social engagement, they reveal little about the underlying mechanisms operating within specific organizational contexts. Limited attention is given to the role of inequality--particularly age and gender--in shaping either the organizations to which we belong or their consequences for our well-being. We address this issue by examining the Red Hat Society, a social organization for middle-aged and older women. Interviews with members (n=52) illustrate how age and gender inequality interact to shape the organization, which can be viewed as a gendered subculture of aging. Drawing on this framework, we discuss four processes through which participation generates benefits for older women involved in age- and gender-segregated organizations: enhancing social networks, countering invisibility, creating positive frames for aging experiences, and promoting youthful identities.

    Full Text Available Abstract Context The age of puberty has fallen over the past 130 years in industrialized, western countries, and this fall is widely referred to as the secular trend for earlier puberty. The current study was undertaken to test two evolutionary theories: (a the reproductive system maximizes the number of offspring in response to positive environmental cues in terms of energy balance, and (b early puberty is a trade-off response for high mortality rate and reduced resource availability. Methods Using a sample of 22 natural-fertility societies of mostly tropical foragers, horticulturalists, and pastoralists from Africa, South America, Australia, and Southeastern Asia, this study compares indices of adolescence growth and menarche with those of fertility fitness in these non-industrial, traditional societies. Results The average age at menarche correlated with the first reproduction, but did not correlate with the total fertility rate TFR or reproductive fitness. The age at menarche correlated negatively with their average adult body mass, and the average adult body weight positively correlated with reproductive fitness. Survivorship did not correlate with the age at menarche or age indices of the adolescent growth spurt. The population density correlated positively with the age at first reproduction, but not with menarche age, TFR, or reproductive fitness. Conclusions Based on our analyses, we reject the working hypotheses that reproductive fitness is enhanced in societies with early puberty or that early menarche is an adaptive response to greater mortality risk. Whereas body mass is a measure of resources is tightly associated with fitness, the age of menarche is not.

    Full Text Available The article offers a short view on a new perspective concerning the future model of ageing lifestyle. What is called the University of the Third Age (UTA or U3A represents above all a real cultural revolution born in developed societies.The structure of the article has two parts. The first presents the general context of the emergence of the phenomenon. The second one focuses on a particular exemple represented by the U3A from Liege. The conclusions of the article emphsize the variety of the movement, including in the Romanian experience, as argument for a new social cooperation that should counterbalance traditional approaches.

    Although the demographic revolution has produced hundreds of millions people aged 65 and older, a substantial segment of that population is not enjoying the benefits of extended healthspan. Many live with multiple chronic conditions and disabilities that erode the quality of life. The consequences are also costly for society. In the United States, the most costly 5% of Medicare beneficiaries account for approximately 50% of Medicare's expenditures. This perspective summarizes a recent workshop on biomedical approaches to best extend healthspan as way to reduce age-related dysfunction and disability. We further specify the action items necessary to unite health professionals, scientists, and the society to partner around the exciting and palpable opportunities to extend healthspan.

    2016-08-01

    Full Text Available Nowadays, scholars have become interested in the ways new media influence young people, but its influence on middle-aged people have not been thoroughly examined. This age category is often ignored as most of the online activities are performed by young persons. New media gathers a wide range of phenomena which may become concepts of the network society through their diversity, knowledge and novelty. Interactivity is the most important characteristic, turning the user into a content creator, not just into a receiver. Moreover, what was once considered to be a personal state of mind tends to become a part of the public domain. Starting from these premises, the article advances the idea that the Internet can be beneficial not just for teenagers, but also for the middle-aged group oriented towards keeping in touch with relatives and friends and towards finding online useful information. At this level, the present paper aims to discover directions given by network society in the lives of middle-aged people. To this end, the research relies on an interview-based survey which addresses the way people may adapt to communication technology and to its particularities, exploring advantages or discovering potential drawbacks.

  4. Population aging.

    1999-04-01

    This paper focuses on the impact of population aging in China, the most densely populated country in the world. Statistics indicate that by the end of 1998, 83.75 million out of the 1.248 billion Chinese people will be over 65 years old. According to the UN standards, China will soon become an aging society. The aging population poses several challenges to the country with the greatest challenge being the increasing social responsibility to care for the aged. With the undeveloped legislative framework to protect the interests of the aged and the serious drawbacks in the pension system to cater only to the income part and not the service part of the aged, China is not yet ready for the advent of aging. Violation of the rights of senior citizens is still very rampant despite enactment of the law on Protection of the Rights of the Elderly in 1996. Moreover, China is not economically ready to become an aging society. China faces this challenge by adopting a three-pronged approach to solve the problem namely: family support, establishment of nursing homes, and creating a social security framework that addresses the needs of the society suited to the Chinese condition. It is believed that with the growing economy of the country and the rising income of its people, a comprehensive social security net will be created to take care of the aged.

  5. Climate hazards, adaptation and "resilience" of societies (early Little Ice Age, west of France).

    Over the past ten to fifteen years, climate hazards and adaptation have received more attention due to the current climate change. Climate historians have gathered strong evidence that the world's climate has evolved over the past millennium and one of the most significant changes took place during the Little Ice Age. Recently, a set of questions has emerged: what were the effects of the Little Ice Age on human's societies? How did humans adapt to these climate changes? How did they react to extreme weather-related events? Using examples of climate hazards from the West of France during the beginning of the Little Ice Age (xivth-xviith centuries) such as storms, flooding, drought, harsh winters, the poster aims at showing how the past societies can constitute a source of inspiration for present ones. Through schemas, this research exposes the system's rebound capacity, points out the importance of the historical depth in research on human's adaptation and resilience and shows the value of integrating a historical approach. It reveals that History contributes to the knowledge of the relationship between societies and climate hazards. Data on climate hazards and adaptation of societies stem from historical sources such as chronicles, diaries, books of accounts, records of cities repairs. To protect themselves and their goods, medieval and modern societies had developed specific skills, practices and strategies. From the xivth to the xviiith century, there is an increase of defense by dikes in the low Loire, as for example the construction of those amongst Longué and Ponts-de-Cé between the early xivth century and 1407. The French kingdom's authorities also tried increasingly to provide technical, material, logistical and fiscal support: for instance, during the winter 1564-1565, several bridges have been destroyed by a river flooding in Nantes. The King Charles IX then offered to people of Nantes part of the funds from taxes on the main activities such as the

    Full Text Available Demographic developments, including an aging population, change pathological models and pressures on health systems sustainability of the European Union. ICT can play a significant role in approaching these challenges because they allow the management and providing of health and social services more efficiently. Health informatics systems have the potential to play an important role in achieving well- being, independent living and delaying of the aging process and restoring the vitality of the mature body. The „Multidisciplinary Complex System for the Efficient Management of the Anti-Aging information (AgingNice” creates favourable conditions for the participation of all at the Information Society. AgingNice allows the sharing of the knowledge concerning the specific research and the promotion of the theoretical and practical information, both among the stakeholders from the medical area and at the citizen’s level. „Informational Centre of Dermatology (CID” is a complex system that has as target to achieve a modern informatics tool able to centralize in a single point a variety of web services and information classified by user’s type. Both health informatics systems demonstrate how ICT can improve the dissemination of health information, knowledge, comprising the users’ motivation concerning educational content and its new promoting methods.

  7. Forecasting Japan's physician shortage in 2035 as the first full-fledged aged society.

    Directory of Open Access Journals (Sweden)

    Koichiro Yuji

    Full Text Available INTRODUCTION: Japan is rapidly becoming a full-fledged aged society, and physician shortage is a significant concern. The Japanese government has increased the number of medical school enrollments since 2008, but some researchers warn that this increase could lead to physician surplus in the future. It is unknown how many physicians will be required to accommodate future healthcare needs. MATERIALS AND METHODS: We simulated changes in age/sex composition of the population, fatalities (the number of fatalities for the consecutive five years, and number of physicians from 2010 to 2035. Two indicators were defined: fatalities per physician and fatalities by physician working hour, based on the data of the working hours of physicians for each tuple of sex and age groups. We estimated the necessary number of physicians in 2035 and the number of new physicians to maintain the indicator levels in 2010. RESULTS: The number of physicians per 1,000 population is predicted to rise from 2·00 in 2010 to 3·14 in 2035. The number of physicians aged 60 years or older is expected to increase from 55,375 (20% of physicians to 141,711 (36%. In 2010 and 2035, fatalities per physician were 23·1 and 24·0 for the total population, and 13·9 and 19·2 for 75 years or older, respectively. Fatalities per physician working hour are predicted to rise from 0·128 to 0·138. If working hours are limited to 48 hours per week in 2035, the number of fatalities per physician working hour is expected to be 0·196, and the number of new physicians must be increased by 53% over the current pace. DISCUSSION: The number of physicians per population continues to rise, but the estimated supply will not fulfill the demand for healthcare in the aging society. Strategies to increase the number of physicians and improve working conditions are urgently needed.

  8. Home educating in an extended family culture and aging society may fare best during a pandemic.

    Full Text Available Large cities can contain populations that move rapidly from one section to another in an efficient transportation network. An emerging air-borne or contact based pathogen could use these transportation routes to rapidly spread an infection throughout an entire population in a short time. Further, in many developed countries, the aging population is increasing. The family structure in these societies may also affect the course of a disease. To help understand the impact of an epidemic on family structure in a networked population, an individual based computer model that randomly generates networked cities with a specified range of population and disease characteristics and individual schedules, infectivity, transmission and hygiene factors was developed. Several salient issues emerged. First, a city of highly active individuals may in fact diminish the number of fatalities because the average duration of the interactions between agents is reduced. Second, home schooling can significantly improve survival because the institutional clustering of weak individuals is minimized. Third, the worst scenario for an aging population is the nuclear family where the aged population is confined to large housing facilities. Naturally, hygiene is the first barrier to infection. The results suggest that societies where extended families and small groups manage most of their own affairs may also be the most suitable for defense against a pandemic. This may prove applicable in city planning and policy making.

    Full Text Available This article will talk about the child in society of Hetman – the autonomous entity within the Russian Empire, which was rapidly losing the remnants of autonomy in the second half of the XVIII century, subjecting to the desire of the center to modernize and unify its border territory. Such interaction of traditions and innovations influenced the public's worldview and determined the attitude to the family, marriage, child. These topics are still relatively poorly studied in the Ukrainian material, particularly the problems of childhood. The studies of actually "little man" in Ukraine of XVIII century are made virtually from a clean slate and at the beginning it is necessary to determine whom society is considered as a child, and also when the childhood is ended. This issue is harder than it seems at first glance, because the society of Hetmanate in relation to children was guided by the stratagem of folk traditions, religious norms, the "old" law (the Lithuanian Statute, the Magdeburg right and sachsenspiegel inherited from the Commonwealth and the "new" laws of the Russian Empire. They determined the age of adulthood in different ways, when the individual became a child and was no longer to be, as well as the criteria of those age limits. It is important that the legal mechanisms of age-identification included in the action in the case of judicial proceedings, property disputes, marital conflicts. On a daily level, the perception of childhood and maturity depended on the combination of external features of an individual (body type, facial features, etc., conduct, and perform social roles. A huge role is played the institution of marriage, act of which was probably the most important and revealing marker of the fact that the kid finally became an adult.

    Prevention, particularly with regard to older people, has assumed increasing importance in policy in recent years. Prevention not only focuses on diseases but also on the geriatric syndrome and frailty must be crucial for the well-being of older people in the super-aged society. The preventive services aim to sustain independent living among those who are vulnerable and the preventive strategies should be supported by an evidence base that links risk factors with particular conditions and interventions to reduce risk and ameliorate the impact of illness and impairments. However, due to the heterogeneity of this population and a paucity of research on this field, it is difficult to make universal recommendations for the preventive services for the older people.

    There is an age related decline in various physiological processes. Vascular ageing is associated with changes in the mechanical and the structural properties of the vascular wall, which leads to the loss of arterial elasticity and reduced arterial compliance. Arterial compliance can be measured by different parameters like pulse wave velocity, augmentation index, and systemic arterial compliance. There is evidence that arterial compliance is reduced in disease states such as hypertension, diabetes, and end stage renal failure. Changes in arterial compliance can be present before the clinical manifestation of cardiovascular disease. Pharmacological and non‐pharmacological measures have been shown to improve arterial compliance. Arterial compliance may constitute an early cardiovascular risk marker and may be useful in assessing the effects of drugs on the cardiovascular system. Pharmacogenetics and genetics of arterial compliance in the future will improve our knowledge and understanding about vascular ageing. PMID:16754702

    This study examined cross-sectional age relations of blood pressure, anthropometric indexes, serum lipids, and hemostatic variables in 203 subsistence horticulturists aged 20-86 y in Kitava, Trobriand Islands, Papua New Guinea. The population is characterized by extreme leanness (despite food abundance), low blood pressure, low plasma plasminogen activator inhibitor 1 activity, and rarity of cardiovascular disease. Tubers, fruit, fish, and coconut are dietary staples whereas dairy products, refined fat and sugar, cereals, and alcohol are absent and salt intake is low. Although diastolic blood pressure was not associated with age in Kitavans, systolic blood pressure increased linearly after 50 y of age in both sexes. Body mass index decreased with age in both sexes. Serum total cholesterol, triacylglycerol, low-density-lipoprotein cholesterol, and apolipoprotein B increased in males between 20 and 50 y of age, whereas high-density-lipoprotein cholesterol and apolipoprotein A-I decreased. There were no significant differences in these indexes with age in the few females studied. A slight linear age-related increase of lipoprotein(a) was present in males. Plasma fibrinogen, factor VII clotting activity, factor VIII clotting activity, and von Willebrand factor antigen increased with age in both sexes but plasminogen activator inhibitor 1 activity did not. The modest or absent relations between the indexes measured and age are apparently important explanations of the virtual nonexistence of stroke and ischemic heart disease in Kitava.

    Liu, T; Flöthmann, E-J

    2013-07-01

    In China, fundamental changes in population development have occurred during the past 50 years. The demographic transition in China required only a few years, while in most European countries this process took several decades. The fertility and mortality rates have declined very quickly, like in Japan and South Korea. China is one of the countries that has passed through the transition process the quickest. In the following article, this development is considered in more detail. Even if the fertility and mortality rates should stabilize at a new low level, which today certainly cannot be conclusively stated, the age effects will persist for the next few decades. The demographic aging during recent years will increase enormously in the coming decades. This development leads to far-reaching social and political challenges. The demographic aging in China is associated with a loss of function of the family. Both developments have a strong impact on the old-age insurance and on old-age care. Only a few years ago did politics and society start to respond with comprehensive reforms. For example, a modern pension system was introduced, but only in urban areas of China. Rural populations are still waiting for such reforms even today. Currently, there is a pilot project to gain experience with a pension system for the entire population. In contrast to the old-age insurance, in China there is very little public interest in old-age care because the elderly have until now been only a matter for the family. In the near future, the changing role of family and demographic aging will require a greater discussion about the care of older people in China.

  2. From Zoomers to Geezerade: Representations of the Aging Body in Ageist and Consumerist Society

    Directory of Open Access Journals (Sweden)

    Suzanne Dupuis-Blanchard

    2013-01-01

    Full Text Available This paper is based on an analysis of representations of seniors in the media. In particular, we examine images of the bodies of seniors in the advertising campaigns promoting a product called Geezerade sold in Circle K convenience stores in the Atlantic provinces of Canada in the summer of 2011. We contrast these with images of seniors in the Canadian magazine Zoomer, formally CARP magazine, a magazine published by the Canadian Association of Retired People, a seniors advocacy organization. Following Goffman’s arguments in his seminal presidential address to the American Sociological Association, “the Interaction Order”, we take the position in this analysis that the body does not determine social practices but none-the-less the body is the sign vesicle that enables interaction. Concomitant however, while the images of bodies we see in the media do not determine the signs given and given off via bodily presentation, they none-the-less provide us with the categories by which we interpret those signs. We conclude that the images in the Geezerade campaign and Zoomer magazine represent a binary model of images of seniors that reflects ageist and classist assumptions about the bodies of seniors. Such a model limits the categories through which we understand the aging body and fails to account for the diversity of seniors’ bodies in society.

  3. Dementia before death in ageing societies--the promise of prevention and the reality.

    2006-10-01

    Full Text Available BACKGROUND: Dementia and severe cognitive impairment are very closely linked to ageing. The longer we live the more likely we are to suffer from these conditions. Given population increases in longevity it is important to understand not only risk and protective factors for dementia and severe cognitive impairment at given ages but also whether protection affects cumulative risk. This can be explored by examining the effect on cumulative risk by time of death of factors found consistently to reduce risk at particular ages, such as education and social status. METHODS AND FINDINGS: In this analysis we report the prevalence of dementia and severe cognitive impairment in the year before death in a large population sample. In the Medical Research Council Cognitive Function and Ageing Study (a 10-y population-based cohort study of individuals 65 and over in England and Wales, these prevalences have been estimated by age, sex, social class, and education. Differences have been explored using logistic regression. The overall prevalence of dementia at death was 30%. There was a strong increasing trend for dementia with age from 6% for those aged 65-69 y at time of death to 58% for those aged 95 y and above at time of death. Higher prevalences were seen for severe cognitive impairment, with similar patterns. People with higher education and social class had significantly reduced dementia and severe cognitive impairment before death, but the absolute difference was small (under 10%. CONCLUSIONS: Reducing risk for dementia at a given age will lead to further extension of life, thus cumulative risk (even in populations at lower risk for given ages remains high. Ageing of populations is likely to result in an increase in the number of people dying with dementia and severe cognitive impairment even in the presence of preventative programmes. Policy development and research for dementia must address the needs of individuals who will continue to experience these

    The oldest of the baby boomers (boomers) were age 63 in 2009 and on the verge of retirement. This cohort has had a history of making societal changes throughout its life cycle, and it is unlikely that retirement, as we know it, will remain unscathed. This article highlights two events-the Stonewall Inn riots and two prominent professional associations removing homosexuality from their list of personality disorders-and how they occurred early enough in the gay boomers life cycle to change their attitudes, behaviors, and lifestyles. This article introduces the reader to a broad array of facts, research findings, and issues that inform the topic of gay aging. A summary of the discrimination and legal concerns affecting the gay community are also highlighted. Two influential community programs are identified: Services and Advocacy for Gay Elders (SAGE) and the American Society on Aging's LGBT Aging Issues Network (LAIN). Gerontological educators need to be sensitive to the needs, desires, and resources of the coming cohort of gay boomers, who are more likely to advocate for responsive services, organizations, and policies than the current cohort of gay older adults.

  7. Process of physical disability among older adults--contribution of frailty in the super-aged society.

    2012-02-01

    One of the critical issues that Japan, well known for the world's highest proportion of older adults, a super-aged society, is currently confronting is how to prevent physical disability in old age. This issue is particularly important not only from a medical perspective such as functional prognoses but also from a socio-economic angle in view of reducing the rapid rise in the cost of medical and long-term care insurance services. Functional decline in old age results not only from acute diseases but also from frailty. Such a common and important syndrome that is increasingly prevalent with advancing age can be the cause. The present article intends to review what is known about frailty, including its definition, epidemiology, and pathophysiology, and to examine potential areas of future research.

    Wide across the Western world, people are living longer lives and having fewer children. This has led to larger shares of elderly voters, who, many fear, are becoming an immensely powerful political pressure group. But what are the effects of population aging on public policy?

    Major economic, political, demographic, social, and operational system factors are prompting evolutionary changes in health care delivery. Of particular significance, the "graying of America" promises new challenges and opportunities for health care social work. At the same time, the Patient Protection and Affordable Care Act of 2010, evolution of Accountable Care Organizations, and an emphasis on integrated, transdisciplinary, person-centered care represent fundamental shifts in service delivery with implications for social work practice and education. This article identifies the aging shift in American demography, its impact on health policy legislation, factors influencing fundamentally new service delivery paradigms, and opportunities of the profession to address the health disparities and care needs of an aging population. It underscores the importance of social work inclusion in integrated health care delivery and offers recommendations for practice education.

    2016-10-01

    Full Text Available The Senior Living Lab (SLL is a transdisciplinary research platform created by four Universities that aims at promoting ageing well at home through the co-creation of innovative products, services and practices with older adults. While most living labs for ageing well are focused on Information and Communication Technologies (ICTs, this social laboratory adopts a transdisciplinary approach, bringing together designers, economists, engineers and healthcare professionals to develop multiple forms of social innovation using participatory methods. The SLL is based on an ecological approach, connecting professionals and users in a cooperative network and involving all of the stakeholders concerned with ageing well, such as existing associations, business entities and policy-makers. Three main themes for the co-design of products and services were identified at the beginning of the SLL conception, each sustained by a major business partner: healthy nutrition to cope with frailty, improved autonomous mobility to foster independence and social communication to prevent isolation. This article shows the innovative transdisciplinary approach of the SLL and discusses the particular challenges that emerged during the first year of its creation, investigating the role of ICTs when designing products and services for older adults.

    Bolognia, J L

    1995-01-16

    Aging of the skin is a composite of actinic damage, chronologic aging, and hormonal influences. The majority of changes associated with aging, such as wrinkles and solar lentigines ("liver spots"), are due to photoaging and reflect cumulative sun exposure as well as skin pigmentation. Classically, chronologic aging includes those cutaneous changes that occur in non-sun-exposed areas, such as the buttocks, and are observed in both men and women. A clinical example would be soft tissue sagging due to elastic fiber degeneration. In women, investigations into the effect of hormones on aging of the skin have concentrated on estrogens; in men, there have been a limited number of studies on the influence of testosterone. The latter have shown an age-dependent decrease in tissue androgens in pubic skin, but not scrotal or thigh skin. To date, age has not been shown to have an effect on androgen receptor binding, although a decrease in foreskin 5 alpha-reductase activity with increasing age has been described. In fibroblast cultures from foreskins, there have been conflicting results as to whether 5 alpha-reductase activity decreases in an age-dependent manner. Some of the skin changes that have been categorized as secondary to chronologic aging, such as decreased sebaceous gland activity and decreased hair growth, may actually represent a decline in the concentration of tissue androgens with increasing age. The influence of androgens on age-related changes in keratinocyte and fibroblast function remains speculative.

    2012-01-01

    Full Text Available INTRODUCTION: While the prolongation of life expectancy is due to medical, economic, social and public health advancements, longevity may not necessarily be an indicator of real development. Epidemiologic data indicate, in fact, that advanced age carries the risk of multiple diseases, disability and loss of autonomy. MATERIALS AND METHODS: How the years gained are lived need to be assessed evaluating quality of life, health status, and disability. RESULTS AND CONCLUSIONS: Good health care planning should aim to ensure that the years of life gained are lived in good health conditions in the light of the World Health Organization's declaration that "increased longevity without quality of life is an empty prize. Health expectancy is more important than life expectancy".

  2. Gender roles and social policy in an ageing society: the case of Japan

    Directory of Open Access Journals (Sweden)

    Meiko Makita

    2010-10-01

    Full Text Available This article reviews the major underpinnings of the Japanese welfare state in the context of social care from a feminist perspective. In Japan, familycare responsibilities have traditionally been assigned to women; hence, care has long been a women’s issue. However, as the social contract of a male breadwinner and a “professional housewife” gradually fades out, Japanese women find more opportunities to renegotiate their caring roles. Of course, this social transformation did not occur in isolation, it was influenced by patterns in economic development, state policies and mainly demographic changes. All this has stimulated new state responses in the form of social welfare expansion that arguably aim to relieve women of the burdens of family-care. The issue remains, however, as to whether Japan would be able to recognise that the main structural issues of population ageing do not originate from demographic changes, but from a strict gendered division of labour and gender inequality.

  3. Prediction of Female Breast Cancer Incidence among the Aging Society in Kanagawa, Japan

    2016-01-01

    Owing to the increasing number of elderly “baby boomers” in Japan, the number of cancer patients is also expected to increase. Approximately 2 million baby boomers from nearby local areas are residing in metropolitan areas; hence, the geographical distribution of cancer patients will probably markedly change. We assessed the expected number of breast cancer (BC) patients in different regions (urban, outer city, town, rural) using estimates of the nation’s population and Kanagawa Cancer Registry data. To estimate future BC incidence for each region, we multiplied the 2010 rate by the predicted female population for each region according to age group. The incidence cases of BC in those aged ≥65 years is expected to increase in all areas; in particular, compared to rates in 2010, the BC incidence in urban areas was predicted to increase by 82.6% in 2035 and 102.2% in 2040. Although the incidence in all BC cases in urban areas showed an increasing trend, until peaking in 2040 (increasing 31.2% from 2010), the number of BC patients would continue to decrease in other areas. The number of BC patients per capita BC specialist was 64.3 patients in 2010; this value would increase from 59.3 in 2010 to 77.7 in 2040 in urban areas, but would decrease in other areas. Our findings suggest that the number of elderly BC patients is expected to increase rapidly in urban areas and that the demand for BC treatment would increase in the elderly population in urban areas.

    Smith, Julia; Buse, Kent; Gordon, Case

    2016-07-16

    Sustainable Development Goal Three is rightly ambitious, but achieving it will require doing global health differently. Among other things, progressive civil society organisations will need to be recognised and supported as vital partners in achieving the necessary transformations. We argue, using illustrative examples, that a robust civil society can fulfill eight essential global health functions. These include producing compelling moral arguments for action, building coalitions beyond the health sector, introducing novel policy alternatives, enhancing the legitimacy of global health initiatives and institutions, strengthening systems for health, enhancing accountability systems, mitigating the commercial determinants of health and ensuring rights-based approaches. Given that civil society activism has catalyzed tremendous progress in global health, there is a need to invest in and support it as a global public good to ensure that the 2030 Agenda for Sustainable Development can be realised.

    2008-04-01

    Due to fundamental demographic as well as social changes, the emergency medical services (EMS) have to respond to an increasing number of geriatric emergencies. By means of some typical case histories the practical problems arising in preclinical emergency medical intervention and the central role of context factors like social isolation, reduced mental capabilities and the resulting need for help are demonstrated. It is discussed how emergency medical services (EMS) can contribute to the problems of an ageing society beyond the scope of a system which is dedicated only to the individual. One possibility is the epidemiological analysis of geriatric emergencies, the accompanying context factors and the development of an adequate infrastructure which is adapted to the needs of the elderly. The EU project EMERGE is an example of how emergency medical expertise is utilized in an interdisciplinary cooperation. An automatically working system based on ambient sensor technology is developed for early detection and prevention of emergency situations in the home environment. Supportive technology ("assisted living") should enable the elderly to live a safe and self-determined life as long as possible. Integration of this additional information into the processes of Emergency Medical Services (EMS) is the logistic prerequisite to establish a social medical assistance tailored to the needs of an ageing society.

    Sleeboom-Faulkner, Margaret

    2010-01-01

    This article explores the reasons for the lack of a broad discussion on bioethical regulation of human embryonic stem cell research (hESR) in Japan and asks why scientists experience difficulties accessing resources for hESR despite the acclaimed indifference of dominant Japanese culture to embryo research. The article shows how various social actors express their views on the embryo and oocyte donation in terms of dominant Japanese culture, foiled against what is regarded as Western culture. Second, it shows how the lack of concern with hESR should be understood in the context of public health policies and communications and bioethics decision making in Japan. Finally, it interprets the meaning of the embryo in the context of Japan as an aging modern welfare society, explaining how policymakers have come to emphasize the urgency of infertility problems over issues around abortion and embryonic life.

    While Japan is becoming a advanced aged and few children society, besides the welfare vehicles for public use and for various institutions, needs for home care, namely the personal use, increases rapidly. Therefore, it is expected that in the near future various welfare vehicles having different structures will be developed to meet to different uses and different needs. The welfare vehicles are roughly divided into two kinds as physically handicapped person self-operating vehicle, and nursing person operating and physically handicapped person boarding on vehicle. In this paper, the later, namely the nursing care vehicles, is introduced. As the nursing care vehicles used at present, transportation vehicles as wheelchair and stretcher, rotary sheet or a vehicle with a sheet lift, movable bath vehicle and other kind of care vehicles are explained respectively. At last, the functions which are required strictly for these nursing care vehicles are mentioned. 5 refs., 9 figs., 2 tabs.

    2000-01-01

    Enormous advances in our understanding of human aging have occurred during the last 50 yr. From the late 19th to the mid-20th centuries only four comprehensive and important sources of information were available: 1. August Weismann's book entitled Essays on Heredity and Kindred Biological Problems (the first of these essays dealt with The Duration of Life; 1). Weissmann states (p. 10) "In the first place in regulating the length of life, the advantage to the species, and not to the individual, is alone of any importance. This must be obvious to any one who has once thoroughly thought out the process of natural selection_". 2. A highly systematized second early source of information on aging was the collection of essays edited by Cowdry and published in 1938. This 900+ page volume contains 34 chapters and was appropriately called Problems of Aging. 3. At about the same time Raymond Pearl published his book on aging (2). Pearl believed that aging was the indirect result of cell specialization and that only the germ line was resistant to aging. Unfortunately Pearl died in the late 1930s and is largely remembered now for having been the founding editor of Quarterly Review of Biology while he was at the Johns Hopkins University, this author's alma mater. 4. Alexis Carrel wrote a monumental scientific and philosophical book, Man, the Unknown (3). Carrel believed that he had demonstrated that vertebrate cells could be kept in culture and live indefinitely, a conclusion challenged by others (more on this later).

    Full Text Available Consumer culture has placed the ageing body in a dilemma of representation. Physical appearance has become increasingly important as a symbol of identity, and at the same time society idealizes youth. This study explores visual ageing empirically. By using photographs of older persons (70+ as starting point, it is explored how visual age is assessed and interpreted. It is shown that informants read age in a spread of stages and categories. Main age indicators are biological markers: skin, eyes, and hair colour, but supplemented by vigour, style, and grooming. Furthermore, in-depth interviews indicate that visual age is mainly interpreted into categories and moral regulations rooted in early modernity. Subsequently the question of a postmodern perspective of visual ageing is discussed in this article. The empirical findings in the study question a postmodern fluidity of visual signs – at least when the concern is signs of ageing.

    2015-10-01

    The ages of rocks from the lunar highlands vary widely, even for a single rock sample. This makes it difficult to quantitatively test ideas for early lunar differentiation and formation of the crust. Lars Borg and Amy Gaffney (Lawrence Livermore National Laboratory), and Charles Shearer (University of New Mexico) have devised a set of guidelines to apply to geochronological data that leads to a relative ranking of the reliability of the age determined for a sample. Applying their guidelines to existing data for lunar highland rocks shows an upper limit on rock ages between 4340 and 4370 million years. This is essentially the same as the so-called model ages of the formation of KREEP (a chemical component enriched in potassium, rare earth elements, and phosphorous) and of the formation of the deep source regions that melted to produce mare basalts. The numerous ages close to 4370 million years suggests a complicated and protracted cooling of the primordial lunar magma ocean or a widespread vigorous period of magmatic activity in the Moon.

    Full Text Available Concept of age estimation plays an important role on both civil law and regulation of criminal behaviors. In forensic medicine, age estimation is practiced for individual requests as well for request of the court. In this study it is aimed to compile the methods of age estimation and to make recommendations for the solution of the problems encountered. In radiological method the epiphyseal lines of the bones and views of the teeth are used. In order to estimate the age by comparing bone radiographs; Greulich-Pyle Atlas (GPA, Tanner-Whitehouse Atlas (TWA and “Adli Tıpta Yaş Tayini (ATYT” books are used. Bone age is found to be 2 years older averagely than chronologic age, especially in puberty, according to the forensic age estimations described in the ATYT book. For the age estimation with teeth, Demirjian method is used. In time different methods are developed by modifying Demirjian method. However no accurate method was found. Histopathological studies are done on bone marrow cellularity and dermis cells. No correlation was found between histopathoogical findings and choronologic age. Important ethical and legal issues are brought with current age estimation methods especially in teenage period. Therefore it is required to prepare atlases of bone age compatible with our society by collecting the findings of the studies in Turkey. Another recommendation could be to pay attention to the courts of age raising trials of teenage women and give special emphasis on birth and population records

    The greatest risk factor for cancer is aging. Human cancer incidence increases exponentially with advancing age. Cancer growth rate and potential for metastatic spread may be influenced by age-specific change in host response. Because cancer and aging are, thus, inextricably linked, the American Cancer Society should encourage submission of research proposals that address the mechanisms of aging and how aging alters cancer development.

    Full Text Available One of the main structural changes human societies are actually facing relies on demographic ageing process, with strong impacts on health system and quality of life. Social and environmental factors can be used as predictors for health conditions, functional and cognitive autonomy, wellbeing and satisfaction on older ages. Reduced incomes, low educational level, situation of loneliness, can also be pointed as predictive factors of a major and premature deterioration of health. The adaptation of social structures must be a priority for all ageing societies. Portugal will also have to find answers to these challenges. The main objective of this study is to understand the process of vulnerability and multiple dependency situations caused by changes in the Portuguese demographic structure, manly regarding old people, as concerns the following aspects: a levels of well-being in ageing regions determined by a statistical indicator; b specific health care and long-term care.

Lett. 76), 348 (1996). the evolving avalanche is governed by an equation of motion with a memory term that ranges over all past events.(S. Boettcher & M. Paczuski, Phys. Rev. E 54), 1082 (1996). The solution for the propagator shows sub-diffusive behavior with a broad exponential tail. Numerical studies of the temporal correlations during avalanches in a variety of SOC systems indicate that history dependence and hierarchical structures are generic features which emerge dynamically from simple local update rules. In particular, we find(S. Boettcher & M. Paczuski, ``Off-Equilibrium Behavior and Aging in Self-Organized Criticality'', (in preparation).) ``aging'' similar to the slow relaxation behavior in disordered systems that move through ``rugged landscapes'' in phase space, such as spin glasses.

      Sometimes, a moment can announce the end of an age. The gold market is like that. Within two transaction days, the gold slumped by 13%and saw a 25%tumble from the high point in August 2011. According to the classic investment theory, a 20%-above decline means the shift from“a bull”to“a bear”market.   The super bear market of gold has lasted a dozen years. But the bull-to-bear shift was completed within only 20 minutes. Wall Street’s analysts and ordinary Chinese people had different understandings to the golden age.   Expecting a bear market, Wall Street continuously dumped gold, resulting in a diving of gold price. Seeing the benefits, leisure Chinese madams made a gold rush, causing a slight bounce of gold price. On April 23, renowned investment bank Goldman Sachs suspended the short sale. So,“Chinese aunts”beating back Wall Street’s analysts became the hottest topic online for the time being.   What are the decisive factors for the crash of gold price? Will the gold market complete a real bull-to-bear shift? Will the golden age of gold be farther or nearer?

  12. New concept of age(ing: Prospective age

    Full Text Available While the last century was the century of world population growth, according to demographers, the XXI century will be century of population aging. Statistics undoubtedly show that number of elderly will continue it’s growth in the future. If old age is seen as period of life with reduced physical and mental capabilities and increased disability, and demographic aging as increase of dependent population, trends are quite disturbing, at least in certain societal segments. In developed countries, this population category is no longer treated as passive or as a "burden of society" and efforts are made for better social inclusion of older people. In contrast to growing interest in this phenomenon, the concepts that define the aging of the population remained stagnant. The aim of this paper is to introduce into domestic literature the term "prospective age" as a dynamic category which is more affected with socio-historical conditions, not only with biological as traditional definition of aging suggested. Papers written by Sanderson and Scherbov offer new methodological options for study of population aging, because it takes into account the biometric rather than chronological approach. Calculation of prospective years is a simple operation that requires pair of the same number of remained life expectancy from life tables for two different periods (the year of concern is index, and the one we are comparing with is standard year, so that phrase "40s is the new 30s" or "70s the new 60s" gets scientific foundation. Average remaining years of life represent a realistic indicator suggesting increased capacity, activity and vitality of individuals, which is due to accepted demographic parameters still considered old. „Prospective threshold“ is defined as the age when life expectancy falls below 15 years (it is subjective choice made by Sanderson and Scherbov, which is also used in this paper and during the elaboration of these ideas three demographic

    At the end of the Bronze Age, important changes took place among the communities of the northeast of the Iberian Peninsula. These changes continue during the seventh and sixth centuries B.C. and are characterized by a gradual formation of a warrior-type aristocracy. But this “elite” did not consolidate its power definitively until the early Iberian Period, establishing the social structure characteristic of the archaic states of the Iberian Period. Nevertheless, there are social differences among inland and coastal territories. In the inland areas (rivers Segre- Cinca, Guadalope and Matarraña-Algás these differences are the result of local development of societies and, in the coastal areas the main changes take place in parallel with a Phoenician trade, integrating them in the Mediterranean world-system. The local response to this phenomenon was not homogeneous. Differences include chronology, settlement processes and distribution of wealth. We analyze here recent studies on this subject, including the issue of the Urnfield Culture and give special emphasis to the main archaeological contributions of the last decade.

    Full Text Available In performing upper blepharoplasty in the elderly, looking younger and keeping the eyelidsharmonious with the rest of the face have to be achieved at the same time. The most importantgoal in upper blepharoplasty for aging is correcting the drooping upper eyelid skin, and inthis process, the surgeon may or may not create a double eyelid fold. The pros and cons haveto be fully discussed with the patient, but the author personally prefers creating a doublefold unless the patient refuses, because it is efficient in correcting and preventing furtherdrooping of the skin. In most patients, the brow is elevated to compensate for the droopingeyelid, and when the drooping is corrected, brow ptosis may ensue. The surgeon has to preparefor these consequences before performing the procedure, and estimate the exact amountof skin to be excised. In the elderly, the skin and the orbicularis oculi muscle is thin, with adecreased amount of subcutaneous fat and retro-orbicularis oculi fat, and in most cases,excision of the skin alone is enough to correct the deformity. Removing large portions ofsoft tissue may also prolong the recovery period. Unlike younger patients, the lower skinflap should not be stretched too much in the elderly, as it may create an aggressive lookingappearance. A few wrinkles in the lower flap should remain untouched to create a naturallook. In this article, the author’s own methods of performing an aging blepharoplasty aredescribed specifically, with a step-by-step guide and surgical tips.

    The paper analyzed various factors regulating the energy demand in aged households and viewed the future residential use energy demand in the aging society. In Part 1, based on the family budget survey annual report, a study was made of the energy consumption situation of aged people and the trend of the future residential energy consumption. In Part 2, a study was conducted based on survey data on the U.K., France, Sweden and Denmark. In Western countries which are the developed countries of aging, the energy conservation policy effectively worked for the space heating demand which is highest of all, and factors of the energy consumption increase by aging were absorbed. However, since in Japan, aging is rapidly advancing and further there are relatively more factors which connect to an increase in energy consumption in aged households as compared with Western countries, it is thought that Japan is in a situation where the energy consumption increases more often, influenced by aged households. 91 refs., 130 figs., 41 tabs.

    Emergency and intensive care unit demographics have changed with the advent of the super-aged society in Japan. Japan has the highest population aging rate in the world. It is now predicted that an increasing number of people will die at higher age. The oldest old individuals show increasing frailty, with an excess vulnerability to stressors. It is believed that frail elderly would receive limited benefit from highly invasive emergency treatment and advanced intensive care which, on the contrary, could bring about harmful effects on frail elderly. So far a number of frail oldest-old nursing home residents with cardiopulmonary arrest have been taken by ambulance to emergency medical centers to receive cardio-pulmonary resuscitation in vain in Japan. Now is the time to stop the harmful ritual. Withholding CPR from frail elderly with severe ADL impairment would not constitute an act of ageism but the act of humanity based on medical evidence.

    Visual disability in individuals aged 50 years and over seeking services of the Royal Blind Society in the years 1984 to 1989, was studied with respect to changes in frequency of major causes together with age and sex of those affected. The results mirror statistics in the UK. Age-related macular degeneration (AMD) accounts for an increasing proportion of visual disability (34% in 1984 to 43% in 1989). Of particular interest was the frequency of disability attributed to cataract. While decreasing (24% in 1984 to 19% in 1989), cataract still represents a significant cause of potentially treatable disability. The authors conclude that there is a changing prevalence of visual disability caused mainly by an increase in AMD and a subgroup of patients attending for services who appear to have a potentially remediable disability. These conclusions affirm the need for close liaison between ophthalmological practitioners and agencies for the blind.

    Stroke risk increases with aging and one third of ischemic strokes occurs in very elderly (> or = 80 years). These are responsible of two thirds of the overall stroke-related morbi-mortality. Stroke in very elderly differs from younger individuals by sex ratio (more women), risk factors (more atrial fibrillation and hypertension) and usually a worse functional outcome. Very elderly are likely to benefit from stroke unit care and early revascularisation treatments although they have historically been excluded from this urgent management. These issues are likely to worsen in the future with the increasing impact of stroke on our aging societies.

    Water is a substance essential for life. It creates the environment of our body, keeps it's homeostasis, enables every biochemical reaction and metabolic processes in human organism. Maternal hydratation is essential for homeostasis of two organisms and drinking water influences the amniotic fluid volume, fetal well-being and removes toxic metabolic products. The chemical contaminants of drinking water and products of it's chlorination and ozonization could be responsible for spontaneous abortion, birth defects and perinatal complications. Therefore it is recommended to drink natural mineral water for women in reproductive age.

  13. Unmaking old age: political and cognitive formats of active ageing.

    Lassen, Aske Juul; Moreira, Tiago

    2014-08-01

    Active ageing is a policy tool that dominates the way the ageing society has been constituted during the last decades. The authors argue that active ageing is an attempt at unmaking the concept of old age, by engaging in the plasticity of ageing in various ways. Through a document study of the different epistemes, models and forms used in the constitution of active ageing policies, the authors show how active ageing is not one coordinated set of policy instruments, but comes in different formats. In the WHO, active ageing configures individual lifestyle in order to expand the plasticity of ageing, based on epidemiological and public health conventions. In the EU, active ageing reforms the retirement behaviour of populations in order to integrate the plasticity of ageing into the institutions, based on social gerontological and demographic conventions. These conventional arrangements are cognitive and political in the way they aim at unmaking both the structures and the expectations that has made old age and format a new ideal of the 'good late life'. The paper examines the role of knowledge in policy and questions whether the formats of active ageing should be made to co-exist, or whether the diversity and comprehensiveness enable a local adaptation and translation of active ageing policies.

    This qualitative research has the aim to know the meaning of the aging process in the work market referring to the aged people. Six aged persons have participated in this research. The data were collected through an interview and were analyzed using the technique of thematically analyze. Three analytical categories emerged: the meaning of aging/to be aged; the meaning of work; the meaning of aging in the work. Concluding, this paper reinforces the theory that the capitalist societies attach excessive value to the work in the human being life. When it isn't into the life--because of the retirement or the unemployment--it compromises the quality of aging/to be aged of the person, mainly if skills and (individual, social and economical) conditions will lack participation and priority to others activities and values in her/his life.

    Age estimation based on the human face remains a significant problem in computer vision and pattern recognition. In order to estimate an accurate age or age group of a facial image, most of the existing algorithms require a huge face data set attached with age labels. This imposes a constraint on the utilization of the immensely unlabeled or weakly labeled training data, e.g. the huge amount of human photos in the social networks. These images may provide no age label, but it is easily to derive the age difference for an image pair of the same person. To improve the age estimation accuracy, we propose a novel learning scheme to take advantage of these weakly labeled data via the deep Convolutional Neural Networks (CNNs). For each image pair, Kullback-Leibler divergence is employed to embed the age difference information. The entropy loss and the cross entropy loss are adaptively applied on each image to make the distribution exhibit a single peak value. The combination of these losses is designed to drive the neural network to understand the age gradually from only the age difference information. We also contribute a dataset including more than one hundred thousand face images attached with their taken dates. Each image is both labeled with the timestamp and people identity. Experimental results on two aging face databases show the advantages of the proposed age difference learning system and the state-of-the-art performance is gained.

    The world elderly population is rapidly increasing. This demographic change represents a new challenge for the society and demands for a multisectorial intervention to promote a long, healthy, and active life span. Between the factors that contribute in fostering a long healthy life, the nutritional regime plays a central role and is recognized as a major factor in the onset of chronic diseases. A better understanding of the interaction between nutrition and ageing is essential to unravel the mechanisms responsible for these positive/negative effects and to identify diet components promoting the quality of life in the old age and to contribute to the prevention of late-life disabilities. At Università Cattolica del Sacro Cuore, the research activity in food science is focusing on four main objectives: food quality, food safety, functional foods and diet balancing. These objectives are the target of multidisciplinary ongoing and future research activities for a better understanding of the link between diet and ageing. Briefly, the different activities are addressed to the study of the following subjects: the most relevant factors affecting food choices and habits of old aged persons; the effects of long term low dose supplementation of conjugated linoleic acid in mouse; the use of low glycemic index and high resistant starch foods to prevent diabetes and obesity; the adjuvant effect of food bacteria for vaccination; the role of food ingredients in disease; the immunosuppression effect of mycotoxins, and its relevance in ageing people; the production of sustainable and natural antioxidant ingredients to encourage a healthy diet. Our research projects emphasize an holistic and integrated approach that, by bringing together complementary research groups, can combine the collective expertise and thus provide a comprehensive assessment of the role of nutrition in healthy ageing people.

    Full Text Available The present article deals with value orientations and their role in men’s lives, particularly, in young people’s lives. This notion was introduced by the American theoretical sociologist T. Parsons, one of the creators of modern theoretical sociology. The scientist made an attempt to construct the structural and analytical theory of social action, combining personal interests (needs and aims and situation, it takes place in. The issue of value orientations remains acute for psychology. Herein we have considered several most important works, relating to the considered issue. Age aspects of young people’s value orientations are of peculiar interest to us. When analyzing this phenomenon, one should take into consideration the psychological formations, inhere for a certain age. In fact every age has its unique structure, which may change when passing from one development stage to another. Basing on this fact, we’ve considered the values, depending on the age features of the youth, relying upon the works of the scientists, working with different categories of the youth, such as: teenagers, students, children of different nationalities. It is not surprising that most scientists have come to the conclusion that the chief role in value orientation belongs to a family, originates in relations with parents and teachers. The positive reinforcement to the future develops throughout life in accordance with a lifestyle of a family, society and political situation in a state.Life orientations as a type of value orientations show different types of young people’s preferences. Value structure of its consciousness has its own specific character, depending on the age peculiarities. The dynamics of the transition from one age to another is accompanied with the reappraisal of values, eventually, influencing the life strategy of the future generation

    Full Text Available Surprisingly, the discourse on ageism hardly profits from stigma research despite their common denominator—discrimination. The goal of this article is to discuss the stigma concept developed on micro-level interactions and apply it to ageism research on the macro level, i.e. using Round 4 data of the representative international European Social Survey (2008. The data analysis is focused on dominant opinions of the Lithuanian population (N=2002 and usual behavior toward older people, while international comparison is used for interpretation of results. The results show that old age in the Lithuanian society is an “open secret” type of stigma: verbal praise of older people, high assessment of their morals and polite declaration of respect conceal intolerance, disregard and discrimination on the behavioral level. The old age stigma is widespread in Lithuania and stronger than in advanced European countries. Its level is close to discrimination particular to other post-communist and Mediterranean countries.

  10. Nutrients, Microglia Aging, and Brain Aging.

    Science.gov (United States)

    Wu, Zhou; Yu, Janchun; Zhu, Aiqin; Nakanishi, Hiroshi

    2016-01-01

    As the life expectancy continues to increase, the cognitive decline associated with Alzheimer's disease (AD) becomes a big major issue in the world. After cellular activation upon systemic inflammation, microglia, the resident immune cells in the brain, start to release proinflammatory mediators to trigger neuroinflammation. We have found that chronic systemic inflammatory challenges induce differential age-dependent microglial responses, which are in line with the impairment of learning and memory, even in middle-aged animals. We thus raise the concept of "microglia aging." This concept is based on the fact that microglia are the key contributor to the acceleration of cognitive decline, which is the major sign of brain aging. On the other hand, inflammation induces oxidative stress and DNA damage, which leads to the overproduction of reactive oxygen species by the numerous types of cells, including macrophages and microglia. Oxidative stress-damaged cells successively produce larger amounts of inflammatory mediators to promote microglia aging. Nutrients are necessary for maintaining general health, including the health of brain. The intake of antioxidant nutrients reduces both systemic inflammation and neuroinflammation and thus reduces cognitive decline during aging. We herein review our microglia aging concept and discuss systemic inflammation and microglia aging. We propose that a nutritional approach to controlling microglia aging will open a new window for healthy brain aging.

  11. Spectral ageing a new age perspective

    2002-01-01

    We present an up-to-date critique of the physical basis for the spectral ageing method. We find that the number of cases where this method may be meaningfully applied to deduce the ages of classical double radio sources is small indeed. This critique is much more than merely a re-expression of anxieties about the calibration of spectral ageing (which have been articulated by others in the past).

  12. THE ROLE OF THE UNIVERSITY IN THE KNOWLEDGE SOCIETY: ETHICAL PERSPECTIVES ON ACADEMIC RESEARCH IN THE AGE OF CORPORATE SCIENCE

    Directory of Open Access Journals (Sweden)

    MARIA CERNAT

    2011-04-01

    Full Text Available Knowledge society lies on the ruins of national culture that thought people to function in a single universal form of science. This type of society is tightly related to a post-national multicultural world that nourishes the erosion of classical (Kantian and Humboldian cultural and scientific foundations of the university. We are now witnessing it’s transformation into a “multiversity” dominated by the competitive international academic market for students and scholars and “commodified” knowledge. The fiscal crisis of publicly financed universities forced them to constantly pursue other forms of income, the industry being the most obvious solution. In the place of universities of reason and culture the drastic decrease of public funding generated the commercialization of the universities. This is because there is an “asymmetric convergence”: while universities are adopting corporate values and principles the industry itself is not influenced by the academic values and norms. The pursuit of knowledge for mere intellectual curiosity and also the conception of the knowledge as a public good have been abandoned in favor of applied research serving corporate interests. The resulting academic capitalism is far from being the best solution to budget cuts and this study is trying to highlight some of advantages but also the most important shortcomings of this present trend in our universities.

  13. [Age(ing), ambivalence and mimicry].

    Science.gov (United States)

    Küpper, Thomas

    2016-01-01

    This essay aims to show that the concept of ambivalence could prove especially productive for gerontology. It is known that age(ing) is a category that is characterized by difference and at the same time delineates a process. Ambivalence is eminently suitable for capturing this duality as it enables us to take into account the dynamics peculiar to age(ing) and move beyond those conventional rigid distinctions which fail to grasp key nuances. These theoretical considerations will be put to the test by looking at the so-called young-old and their ambivalent positioning as well as their own mimicry of the middle-agers.

  14. Reprogramming aging and progeria.

    Science.gov (United States)

    Freije, José M P; López-Otín, Carlos

    2012-12-01

    The aging rate of an organism depends on the ratio of tissue degeneration to tissue repair. As a consequence, molecular alterations that tip this balance toward degeneration cause accelerated aging. Conversely, interventions can be pursued to reduce tissue degeneration or to increase tissue repair with the aim of delaying the onset of age-associated manifestations. Recent studies on the biology of stem cells in aging have revealed the influence of systemic factors on their functionality and demonstrated the feasibility of reprogramming aged and progeroid cells. These results illustrate the reversibility of some aspects of the aging process and encourage the search for new anti-aging and anti-progeria interventions.

  17. Productive aging: a feminist critique.

    Science.gov (United States)

    Holstein, M

    1992-01-01

    This essay offers a feminist perspective on the call for a "productive aging" society, and says that the movement provides an answer before we have systematically asked questions about the meaning of old age. An emphasis on productivity, among other things, can devalue relational activities, often inherent in women's roles, and certain older people-older women in particular. The author proposes a number of measures for the short term, so that society can be responsible to older women who need and want jobs, as well as ideas for more far-reaching change.

  18. Public Open Space Development for Elderly People by Using the DANP-V Model to Establish Continuous Improvement Strategies towards a Sustainable and Healthy Aging Society

    Directory of Open Access Journals (Sweden)

    Bo-Wei Zhu

    2017-03-01

    Full Text Available With the global trend of population aging, how to integrate the health needs of elderly people into public open space (POS development while taking into account public interest is a major challenge in the 21st century. Although the issues of elderly people’s health and their POS needs are receiving increasing attention, research on continuous improvement strategies for POS for healthy aging societies is still limited. Hence, this study explored continuous improvement strategies thoroughly and systematically by using the DANP-V model. The findings revealed cognitive differences between expert and elderly groups. Moreover, water features, waste management, and co-maintenance spaces were the three criteria with the largest gap value. POS improvement has previously been implemented based on a priority order ranked from the criterion with largest gap value to the criterion with the smallest one. However, an alternative approach based on the cause–effect relationship is proposed in this paper. The study findings have both theoretical and practical implications for POS planners and designers.

  20. Age determination of raccoons

    Science.gov (United States)

    Grau, G.A.; Sanderson, G.C.; Rogers, J.P.

    1970-01-01

    Age criteria, based on 61 skulls and eye lenses from 103 known-age captives, are described for separating raccoons (Procyon lotor) into eight age-classes as follows: young-of-the-year, 1, 2, 3, 4, 5, 6-7, > 7 years. Criteria studied were eye lens nitrogen, cranial suture closure, tooth wear and incisor cementum layers. Lens nitrogen increased rapidly up to 12 months of age, but at much reduced rate thereafter. Total lens nitrogen was useful only in separating young-of-the-year from adults. The closure sequence for five cranial sutures accurately divided the total known-age sample of males into seven groups, and the adults into five groups. The tooth wear criteria divided the known-age sample into five relative age groups, but aging of individuals by this method was inaccurate. Histological sectioning of known-age teeth was the best method of observing layering in the cementum tissue. The technique of basing estimation of age on cementum ring counts, although subjective, was accurate for aging individuals through their fourth year but tended to underestimate the age of animals over 4 years old. However, suture closure or tooth wear can be used to identify males over 4 years old. In field studies, technical difficulties limit the utility of age estimation by cementum layers. Maximum root thickness of the lower canine was accurate in determining the sex of individuals from 5 months to ,at least 48 months of age.

  1. Ageing and infertility: an overview.

    Science.gov (United States)

    Balasch, Juan

    2010-12-01

    In many modern societies, the proportion of women who delay childbearing beyond the age of 35 years has increased greatly in recent decades. They are falsely reassured by popular beliefs that advances in new reproductive technologies can compensate for the age-realted decline in fertility, but science cannot beat the biological clock. Age is the single most important determinant of male and female fertility, either natural or treated. The consequences of advancing maternal age are not only for the risk of natural and assisted conception, but also for the outcome of pregnancy. Female fertility has a 'best-before date' of 35, and for men, it is probably before age 45-50.

    2009-04-01

    Vaccines are an underused public health strategy for healthy aging. Considering the risks of vaccine-preventable diseases and the current low vaccine coverage rates in older European citizens, the two European geriatric and gerontological societies (European Union Geriatric Medicine Society [EUGMS] and International Association of Gerontology and Geriatrics-European Region [IAGG-ER]) convened a Joint Vaccine Working Group to develop a consensus document advocating routine vaccination of aging populations. The mandate of this Working Group was to improve the uptake of routine vaccinations in adults aged 60 years and over. The consensus statement underlines the need to establish, strengthen, and harmonize European policies that continue routine vaccinations to adulthood and that will include older populations. Improved vaccination rates will promote healthy aging by reducing the burden of vaccine-preventable infectious diseases in older populations, a population that is rapidly increasing in Europe.

To demonstrate the necessity of the two-child policy, this paper first uses population data to form an aging timetable and establish the forecasting and analytical model to observe the impact of family planning policy on total population and population structure. Then the paper further demonstrates the feasibility of two-child policy by a case study. Based on the above analysis, one can draw a conclusion that the connotation of family planning policy should be changed from“birth control”to“adjusting population structure and controlling the total population”. Finally, the ways of implementation are discussed.

    Even those who do not experience dementia or mild cognitive impairment may experience subtle cognitive changes associated with aging. Normal cognitive changes can affect an older adult's everyday function and quality of life, and a better understanding of this process may help clinicians distinguish normal from disease states. This article describes the neurocognitive changes observed in normal aging, followed by a description of the structural and functional alterations seen in aging brains. Practical implications of normal cognitive aging are then discussed, followed by a discussion of what is known about factors that may mitigate age-associated cognitive decline.

    Ageing, which all creatures must encounter, is a challenge to every living organism. In the human body, it is estimated that cell division and metabolism occurs exuberantly until about 25 years of age. Beyond this age, subsidiary products of metabolism and cell damage accumulate, and the phenotypes of ageing appear, causing disease formation. Among these age-related diseases, neurodegenerative diseases have drawn a lot of attention due to their irreversibility, lack of effective treatment, and accompanied social and economical burdens. In seeking to ameliorate ageing and age-related diseases, the search for anti-ageing drugs has been of much interest. Numerous studies have shown that the plant polyphenol, resveratrol (3,5,4'-trihydroxystilbene), extends the lifespan of several species, prevents age-related diseases, and possesses anti-inflammatory, and anti-cancer properties. The beneficial effects of resveratrol are believed to be associated with the activation of a longevity gene, SirT1. In this review, we discuss the pathogenesis of age-related neurodegenerative diseases including Alzheimer's disease, Parkinson's disease and cerebrovascular disease. The therapeutic potential of resveratrol, diet and the roles of stem cell therapy are discussed to provide a better understanding of the ageing mystery.

    2010-03-01

    Two cable types, which currently are used in nuclear power plants (NPP) and which are composed by jacket/insulation materials, i.e. PVC/PVC and PVC/PE, were exposed to accelerated ageing conditions, in order to simulate their behavior after 10 years in service. The cables were aged under two different test conditions: With relatively high accelerating ageing speed:Radiation ageing was carried out at room temperature at a dose rate of 2900 Gy/h, followed by thermal ageing at 100 °C. This accelerated ageing condition was fairly fast, but still in compliance with the standards. With moderate ageing speed:The radiation and thermal ageing was performed simultaneously (superimposed) at a dose rate of 2.7-3.7Gy/h and a temperature of 68-70 °C. Such a test condition seems to be very close to the radiation and temperature impact onto the cables in the real NPP service. Finally, mechanical properties were measured to characterize the ageing status of the cables. The purpose of this study was to compare degradation effects, derived from both ageing methods, and to demonstrate that results obtained from high values of accelerating parameters and from fast ageing simulation can be very different from reality. The observed results corroborated this assumption.

  7. Ages of young stars

    2013-01-01

    Determining the sequence of events in the formation of stars and planetary systems and their time-scales is essential for understanding those processes, yet establishing ages is fundamentally difficult because we lack direct indicators. In this review we discuss the age challenge for young stars, specifically those less than ~100 Myr old. Most age determination methods that we discuss are primarily applicable to groups of stars but can be used to estimate the age of individual objects. A reliable age scale is established above 20 Myr from measurement of the Lithium Depletion Boundary (LDB) in young clusters, and consistency is shown between these ages and those from the upper main sequence and the main sequence turn-off -- if modest core convection and rotation is included in the models of higher-mass stars. Other available methods for age estimation include the kinematics of young groups, placing stars in Hertzsprung-Russell diagrams, pulsations and seismology, surface gravity measurement, rotation and activ...

  8. Can aging be programmed?

    DEFF Research Database (Denmark)

    Kowald, Axel; Kirkwood, Thomas B. L.

    2016-01-01

    The evolution of the aging process has long been a biological riddle, because it is difficult to explain the evolution of a trait that has apparently no benefit to the individual. Over 60 years ago, Medawar realized that the force of natural selection declines with chronological age because...... of unavoidable environmental risks. This forms the basis of the mainstream view that aging arises as a consequence of a declining selection pressure to maintain the physiological functioning of living beings forever. Over recent years, however, a number of articles have appeared that nevertheless propose...... the existence of specific aging genes; that is, that the aging process is genetically programmed. If this view were correct, it would have serious implications for experiments to understand and postpone aging. Therefore, we studied in detail various specific proposals why aging should be programmed. We find...

  9. Aging and the aged in Aesopic fables.

    Science.gov (United States)

    Wortley, J

    1997-01-01

    Little attempt has been made to re-assess the attitudes to aging and old age of the ancient-medieval Greek-speaking world on the basis of the literary remains (which are common to both) since Richardson (1933). There are however some collections (proverbs, sayings, "purple passages" from literature and so forth) which include material revealing attitudes which are in fact quite different from those of today and which can even be surprising. One such collection, the large number of fables which more or less conform to the genre associated with Aesop, is here analyzed to isolate the texts which have to do with aging and the attitudes they reveal. Of the surprisingly few fables which touch upon the matter, most are distinctly complimentary. In most instances the elderly are seen to increase, rather diminish, in certain powers other than physical strength. Fables are found which characterize them as being astute, intelligent, crafty, loyal and, above all, capable of giving sound advice and good leadership when the situation requires it of them. The celebrated Fable of the Tortoise and the Hare, although it was not specifically interpreted in this way in ancient times, best sums up the general attitude: that dogged persistence (the characteristic of the elderly) will ultimately prove superior to all the erratic bursts of youthful speed anytime. Hence Cicero: "Old age is more spirited than youth, and stronger!"

  10. Mitochondria and the aging heart

    The average human life span has markedly increased in modern society largely attributed to advances in medical and therapeutic sciences that have successfully reduced important health risks.However,advanced age results in numerous alterations to cellular and subcellular components that can impact the overall health and function of an individual.Not surprisingly,advanced age is a major risk factor for the development of heart disease in which elderly populations observe increased morbidity and mortality.Even healthy individuals that appear to have normal heart fimction under resting conditions,actually have an increased susceptibility and vulnerability to stress.This is confounded by the impact that stress and disease can have over time to both the heart and vessels. Although, there is a rapidly growing body of literature investigating the effects of aging on the heart and how age-related alterations affect cardiac fimction, the biology of aging and underlying mechanisms remain unclear .In this review,we summarize effects of aging on the heart and discuss potential theories of cellular aging with special emphasis on mitochondrial dysfunction.

    The growing proportion of elderly people represents an increasing economic burden, not least because of age-associated diseases that pose a significant cost to the health service. Finding possible interventions to age-associated disorders therefore have wide ranging implications. A number of genetically defined accelerated aging diseases have been characterized that can aid in our understanding of aging. Interestingly, all these diseases are associated with defects in the maintenance of our genome. A subset of these disorders, Cockayne syndrome, Xeroderma pigmentosum group A and ataxia-telangiectasia, show neurological involvement reminiscent of what is seen in primary human mitochondrial diseases. Mitochondria are the power plants of the cells converting energy stored in oxygen, sugar, fat, and protein into ATP, the energetic currency of our body. Emerging evidence has linked this organelle to aging and finding mitochondrial dysfunction in accelerated aging disorders thereby strengthens the mitochondrial theory of aging. This theory states that an accumulation of damage to the mitochondria may underlie the process of aging. Indeed, it appears that some accelerated aging disorders that show neurodegeneration also have mitochondrial dysfunction. The mitochondrial alterations may be secondary to defects in nuclear DNA repair. Indeed, nuclear DNA damage may lead to increased energy consumption, alterations in mitochondrial ATP production and defects in mitochondrial recycling, a term called mitophagy. These changes may be caused by activation of poly-ADP-ribose-polymerase 1 (PARP1), an enzyme that responds to DNA damage. Upon activation PARP1 utilizes key metabolites that attenuate pathways that are normally protective for the cell. Notably, pharmacological inhibition of PARP1 or reconstitution of the metabolites rescues the changes caused by PARP1 hyperactivation and in many cases reverse the phenotypes associated with accelerated aging. This implies that modulation

These changes include decreases in the volume of the thoracic cavity, reduced lung volumes, and alterations in the muscles that aid respiration. Muscle function on a cellular level in the aging population is less efficient. The elderly population has less pulmonary reserve, and cough strength is decreased in the elderly population due to anatomic changes and muscle atrophy. Clearance of particles from the lung through the mucociliary elevator is decreased and associated with ciliary dysfunction. Many complex changes in immunity with aging contribute to increased susceptibility to infections including a less robust immune response from both the innate and adaptive immune systems. Considering all of these age-related changes to the lungs, pulmonary disease has significant consequences for the aging population. Chronic lower respiratory tract disease is the third leading cause of death in people aged 65 years and older. With a large and growing aging population, it is critical to understand how the body changes with age and how this impacts the entire respiratory system. Understanding the aging process in the lung is necessary in order to provide optimal care to our aging population. This review focuses on the nonpathologic aging process in the lung, including structural changes, changes in muscle function, and pulmonary immunologic function, with special consideration of obstructive lung disease in the elderly.Keywords: aging, lung, pulmonary immunology, COPD

    2013-08-01

    Sexuality is an important component of emotional and physical intimacy that men and women experience throughout their lives. Research suggesting that a high proportion of men and women remain sexually active well into later life refutes the prevailing myth that aging and sexual dysfunction are inexorably linked. Age-related physiological changes do not render a meaningful sexual relationship impossible or even necessarily difficult. Many of these physiological changes are modifiable. There are various therapeutic options available to patients to achieve maximum sexual capacity in old age. This article reviews the prevalence of sexual activity among older adults, the problems these adults encounter with sexual activity, and the role of the health care professional in addressing these problems. The physiological sex-related changes that occur as part of the normal aging process in men and women are reviewed, as well as the effect of age-related physical and psychological illness on sexual function. The attitudes and perceptions of the media and general public toward sexual activity and aging are summarized. An understanding of the sexual changes that accompany the aging process may help general practitioners and other doctors to give practical and useful advice on sexuality as well as refute the misconception that aging equates to celibacy. A thorough awareness of this aspect of older people's quality of life can raise meaningful expectations for aging patients.

    The anorexia of aging is common, leading to adverse health consequences. As populations age, the impacts from anorexia in the older population are set to increase. Only greater awareness will allow for prevention or early intervention. This article discusses the physiologic anorexia of aging, highlights contributing factors, and proposes management strategies, including screening, especially in primary care. Many neuroendocrine factors have been implicated in the pathophysiology; it is clear that further human research is necessary if there is to be a pharmacologic breakthrough. There are currently no approved pharmacologic treatment strategies to prevent or treat the anorexia of aging.

    Contemporarily, the Chinese demographic structure is entering the era of profound aging society. But our understandings of aging society, including the ones on conceptualization, institution, and discourse are still unclear and remain in a rudimentary state. Only by developing a societal discourse system based on scientiifc understanding of aging society could we explore the reality of aging society. The media has unique advantage to construct discourse system because of its capacity of inlfuence and spread. To play an important role in constructing discourse system for an aging society,one could start from consciousness of responsibility, self-accomplishment and adjustment of values.%目前,中国在人口年龄结构上正在进入深度老龄社会,但我们关于老龄社会的认知依然模糊,对老龄社会的社会理念、制度,包括话语体系等仍停留在年轻社会。只有循着科学的老龄观,构建老龄社会话语体系,才能深入探究老龄社会的客观真实。传媒因其独特的影响力和传播力,在构建老龄社会话语体系中有着独特的优势,其可以从责任自觉、媒体素养、调整价值观等方面着手,构建老龄社会话语体系。

    Full Text Available Objective: This exploratory study sought to measure current self-reported experiences of older Saudi adults. Method: Self-reported aging perceptions and demographic data from semistructured questions were obtained from 52 community-dwelling older Saudi adults aged 50 or older. A thematic content analysis was completed around issues of family life/social support, daily/weekly activities, health and health programs, and older adults’ own thoughts about aging and the experience and future of personal aging. Results: Several key themes emerged from the interviews. The majority of respondents in this preliminary study acknowledge a preference for family care. Formal programs in Saudi Arabia are attended with relative infrequency while older adults recognize family support as the preferred method of support. Older Saudi interviewees hold a positive view of aging, but physical functioning, varying financial resources, and other daily obligations are a concern for those in this study. Discussion: Data suggest as the Saudi population ages, more research is needed on the aging experience with particiular emphasis on issues relevant to older adults . Future research must work to clarify the aging experience as cultural context changes.

An experimental study previously conducted with young participants was replicated with elderly persons in order to assess the effect of age on the ability to control myoelectric amplitude (or myocontrol. Participants performed pointing tasks as the myoelectric amplitude was captured by a surface electrode in two modalities (sustained: stabilize the amplitude after reaching the desired level; impulsion: return immediately to resting amplitude. There was a significant decrease of performance with Age. However, the patterns of performance of young and aged were noticeably similar. The Impulsion modality was difficult (high rates of failure and the speed-accuracy trade-offs predicted by Fitts' law were absent (bow-shaped patterns as function of target amplitude instead of logarithmic increase. Conversely, the reach phase of the Sustained modality followed the predictions of Fitts' law. However, the slope of the regression line with Fitts' index of difficulty was quite steeper in aged than in young participants. These findings suggest that 1 all participants, young and aged, adapt their reaching strategies to the anticipated state (sustained amplitude or not and/or to the difficulty of the task, 2 myocontrol in aged persons is more fragile, i.e., performance is markedly degraded as the difficulty of the task increases. However, when individual performance was examined, some aged individuals were found to perform as well as the young participants, congruently with the literature on good aging.

    2015-01-01

    The best-known phenomenon exemplifying epigenetic drift (the alteration of epigenetic patterns during aging) is the gradual decrease of global DNA methylation. Aging cells, different tissue types, as well as a variety of human diseases possess their own distinct DNA methylation profiles, although the functional impact of these is not always clear. DNA methylation appears to be a dynamic tool of transcriptional regulation, with an extra layer of complexity due to the recent discovery of the conversion of 5-methylcytosine into 5-hydroxymethylcytosine. This age-related DNA demethylation is associated with changes in histone modification patterns and, furthermore, we now know that ncRNAs have evolved in eukaryotes as epigenetic regulators of gene expression. In this review, we will discuss current knowledge on how all these epigenetic phenomena are implicated in human aging, and their links with external, internal and stochastic factors which can affect human age-related diseases onset.

    2013-01-01

    We study chemical aging in "COOEE bitumen" using molecular dynamic simulations. The model bitumen is composed of four realistic molecule types: saturated hydrocarbon, resinous oil, resin, and asphaltene. The aging reaction is modelled by the chemical reaction: "2 resins $\\rightarrow$ 1 asphaltene". Molecular dynamic simulations of four bitumen compositions, obtained by a repeated application of the aging reaction, are performed. The stress autocorrelation function, the fluid structure, the rotational dynamics of the plane aromatic molecules, and the diffusivity of each molecule, are determined for the four different compositions. The aging reaction causes a significant dynamics slowdown, which is correlated to the aggregation of asphaltene molecules in larger and dynamically slower nanoaggregates. Finally, a detailed description of the role of each molecule types in the aggregation and aging processes is given.

    Parylene C is used in a device because of its conformable deposition and other advantages. Techniques to study Parylene C aging were developed, and "lessons learned" that could be utilized for future studies are the result of this initial study. Differential Scanning Calorimetry yielded temperature ranges for Parylene C aging as well as post-deposition treatment. Post-deposition techniques are suggested to improve Parylene C performance. Sample preparation was critical to aging regimen. Short-term (%7E40 days) aging experiments with free standing and ceramic-supported Parylene C films highlighted "lessons learned" which stressed further investigations in order to refine sample preparation (film thickness, single sided uniform coating, machine versus laser cutting, annealing time, temperature) and testing issues ("necking") for robust accelerated aging of Parylene C.

    Pathologic studies of the myocardium and valvular structures have failed to provide convincing evidence of gross or microscopic changes that can be ascribed to aging alone. Lipofuscin accumulation and basophilic degeneration in cardiac muscle cells appear to be the most consistent findings associated with aging, but they are found in other conditions. Without doubt, pathologic changes in the myocardium, valves, and coronary arteries are found more frequently in the hearts of elderly persons, but those changes are caused by disease processes associated with an aging population rather than the aging process itself. Both the sinus and atrioventricular nodes decrease in size with age owing to a loss of cellularity. These structures become infiltrated with collagen, elastic tissue, and reticular fibers. Some have found infiltration also with fat. Amyloid deposition, basophilic degeneration of cells, and lipofuscin accumulation occur but probably do not cause functional abnormalities. Similar but less dramatic changes occur in the bundle of His and individual bundle branches. Most of the data suggests that these aging changes are not due to vascular insufficiency. Age-related changes in intrinsic mechanical function have been identified as a prolongation of contraction duration, decreased inotropic responses to catecholamines and cardiac glycosides, and an increase in mechanical refractoriness. Other possible age-related changes include alterations in relaxation, which may or may not be independent of the prolongation of contraction, and changes in the viscoelastic properties of cardiac muscle. When examined in the context of the components of a model of excitation-contraction coupling, changes in action potential duration and the function of the sarcoplasmic reticulum emerge as the most likely bases for the changes. The electrical characteristics of sinus, atrioventricular, and His-Purkinje cells as well as atrial and ventricular muscle cells change with age. The sinus

With this intent, we first present a brief history of the vision of death over time and after an analysis of the process of aging and dying according to the logic of biopolitical management. With death and old age increasingly distant from the horizons of life, subjectivity has been weakened. Thus, incorporating these aspects as part of existence constitutes one of the challenges to the thought as well as to the building of the self.

    In the last 5 years, the phrase "politics of envy" has appeared more than 621 times in English-language newspapers, generally in opinion essays contending that political liberalism reflects and exploits feelings of envy.

    Epithelial senescence is a complex process depending on intrinsic as well as extrinsic factors (e.g., UV or IR light, tobacco smoke) and must be seen in the context of the aging process especially of the corium and the subcutis. Morphological alterations become apparent in the form of epithelial atrophy, structural changes within the basal membrane, and a decrease in cell count of melanocytes and Langerhans cells. Signs of cellular senescence are reduced proliferation of keratinocytes, cumulation of dysplastic keratinocytes, various mutations (e.g., c-Fos/c-Jun, STAT3, FoxO1), as well as multiple lipid or amino acid metabolic aberrations (e.g., production of advanced glycation endproducts). This causes functional changes within the physical (lipid deficiency, water distribution dysfunction, lack of hygroscopic substances), chemical (pH conditions, oxygen radicals), and immunological barrier. Prophylactically, barrier-protective care products, antioxidant substances (e.g., vitamin C, B3, E, polyphenols, flavonoids), sunscreen products/measurements, and retinoids are used. For correcting alterations in aged epidermis, chemical peelings (fruit acids, β-hydroxy acid, trichloroacetic acid, phenolic compounds), non-ablative (IPL, PDL, Nd:YAG) as well as ablative (CO2, Erbium-YAG) light-assisted methods are used.

  13. Myths of ageing.

    2007-01-01

    Historical and contemporary images of ageing have generally reinforced negative stereotypes of old age. An examination of sculpture, painting, poetry, literature and film, as well as television, advertising, newspaper stories, birthday cards and road signs reveals that old age is often shown as being a time of loneliness, depression and physical decline. These conditions do occur but their prevalence and severity have been exaggerated. There are many myths of ageing that have been influenced by these representations: that old people with physical or cognitive decline are social problems; that families no longer care for their elders; that geriatric medicine is an unglamorous specialty. Low expectations of old people and ageist thinking can adversely affect how we speak of disadvantaged old people. The challenge is to question inaccurate assumptions. Key to the improvement of medical care of older people is to extend the teaching of geriatric medicine and improve and coordinate research.

    Full Text Available Until recently it was thought that aging is a characteristic feature only of cells and organisms of eukaryotic origin. Recent studies on Caulobacter crescentus showed that their dimorphic life cycle associated with asymmetric cell division leads to a gradual increase in the time needed for the development of new bacteria generations, which may reflect aging of this organism. Moreover, as shown in Escherichia coli, accelerated exhaustion of proliferative capacity and bacteria death are caused by inheritance of certain structures from the mother cell during cell division. A similar phenomenon, called ‘conditional senescence’, has been observed during the stationary phase of growth in liquid cultures. The aim of this paper is to present the current state of knowledge on the causes, mechanisms and evolutionary significance of aging in bacteria. Some issues associated with bacterial aging will be discussed in the context of similar phenomena occurring in eukaryotic cells.

    Twenty-one years have now passed since the launch of Europhysics Letters which merged the physics letters journals of two learned societies: Journal de Physique Lettres and Lettere al Nuovo Cimento belonging, respectively, to the French Physical Society (SFP) and to the Italian Physical Society (SIF). This new journal was also supported by the UK Institute of Physics (IOP) and many other National Physical Societies, members of the European Physical Society (EPS). The aim of this merger was expressed by the words of G. H. Stafford, the President of EPS in 1985, for whom Europhysics Letters marked `an important milestone in the progress towards greater unity in Europe' which began with the creation of the European Physical Society nearly twenty years earlier. Europhysics Letters was supposed to be a strong European-based journal for the publication of short important communications covering all domains of physics under the supervision and the scientific control of EPS. In 2007, 21 years later, Europhysics Letters has now come of age and the Board of Directors, under the control of EPS, has decided to mature the journal, now re-branded as EPL and characterized by a new cover design and a new printed format, thus encouraging development into a top-tier journal, a leading global home for ground-breaking physics research letters. The objective is to make EPL a high-impact physics journal leading towards an increase in visibility, impact, prestige, scientific quality, reputation and impact factor although all scientists are currently aware that the presentation of impact factors must be taken with a grain of salt. A new publishing contract amongst the EPL partners will directly involve, besides EDPS (the publishing company of SFP) and SIF, the Institute of Physics through its publishing department (IOP Publishing) in a more active role, its task being hosting the on-line facilities of the journal.

    Kirkland, James L; Stout, Michael B; Sierra, Felipe

    2016-11-01

    Recently discovered interventions that target fundamental aging mechanisms have been shown to increase life span in mice and other species, and in some cases, these same manipulations have been shown to enhance health span and alleviate multiple age-related diseases and conditions. Aging is generally associated with decreases in resilience, the capacity to respond to or recover from clinically relevant stresses such as surgery, infections, or vascular events. We hypothesize that the age-related increase in susceptibility to those diseases and conditions is driven by or associated with the decrease in resilience. Thus, a test for resilience at middle age or even earlier could represent a surrogate approach to test the hypothesis that an intervention delays the process of aging itself. For this, animal models to test resilience accurately and predictably are needed. In addition, interventions that increase resilience might lead to treatments aimed at enhancing recovery following acute illnesses, or preventing poor outcomes from medical interventions in older, prefrail subjects. At a meeting of basic researchers and clinicians engaged in research on mechanisms of aging and care of the elderly, the merits and drawbacks of investigating effects of interventions on resilience in mice were considered. Available and potential stressors for assessing physiological resilience as well as the notion of developing a limited battery of such stressors and how to rank them were discussed. Relevant ranking parameters included value in assessing general health (as opposed to focusing on a single physiological system), ease of use, cost, reproducibility, clinical relevance, and feasibility of being repeated in the same animal longitudinally. During the discussions it became clear that, while this is an important area, very little is known or established. Much more research is needed in the near future to develop appropriate tests of resilience in animal models within an aging context

  19. Epidemiological aspects of ageing.

    Khaw, K T

    1997-12-29

    A major societal challenge is to improve quality of life and prevent or reduce disability and dependency in an ageing population. Increasing age is associated with increasing risk of disability and loss of independence, due to functional impairments such as loss of mobility, hearing and vision; a major issue must be how far disability can be prevented. Ageing is associated with loss of bone tissue, reduction in muscle mass, reduced respiratory function, decline in cognitive function, rise in blood pressure and macular degeneration which predispose to disabling conditions such as osteoporosis, heart disease, dementia and blindness. However, there are considerable variations in different communities in terms of the rate of age-related decline. Large geographic and secular variations in the age-adjusted incidence of major chronic diseases such as stroke, hip fracture, coronary heart disease, cancer, visual loss from cataract, glaucoma and macular degeneration suggest strong environmental determinants in diet, physical activity and smoking habit. The evidence suggests that a substantial proportion of chronic disabling conditions associated with ageing are preventable, or at least postponable and not an inevitable accompaniment of growing old. Postponement or prevention of these conditions may not only increase longevity, but, more importantly, reduce the period of illnesses such that the majority of older persons may live high-quality lives, free of disability, until very shortly before death. We need to understand better the factors influencing the onset of age-related disability in the population, so that we have appropriate strategies to maintain optimal health in an ageing population.

    2015-01-01

    Magnesium (Mg) is relatively stable in the intracellular compartment, although decreases linearly with advancing age. This begs the question as to whether Mg could be used as biomarker of aging. A biomarker of aging is a biological parameter of an organism that, in the absence of disease, better predicts functional capability at a later age than the chronological age. Bone and muscle Mg content might be useful biomarkers, but the need for biopsies and the heterogeneous distribution of Mg in bones and muscles strongly limit the application of these methods in clinical practice. Similar considerations can be made for urinary Mg assessment, particularly after a loading test. Markers of Mg in blood seem fairly unreliable as biomarkers of aging since they are strongly dependent upon renal function, do not reflect the intracellular Mg status, and, in some investigations, are within normal ranges although other Mg parameters are not. Other investigations (e.g. nuclear magnetic resonance with fluorescent probes) seem to be promising, but their availability remains limited.

    In this contribution, the significance of the salutogenic model (Antonovsky) and its core concept-the sense of coherence-for research into "successful aging" is explicated on the background of a gerodynamic perspective (Schroots). Common to both approaches is the idea that the basic principle of life is based on imbalance, disease, and suffering (heterostasis). According to this pessimistic view, aging is considered as the individual time dimension on which these inevitable impairments in biological, behavioral, and social respects take place. The continuous increase in entropy (disorder) will finally result in the death of the organism. In the face of gerontological research showing variability and individual plasticity in aging processes-especially for the third age-, the salutogenic question is why some people generally become (very) old and stay healthy. According to the salutogenic model, the sense of coherence determines the (re-)production of order over the life span and mediates the relationship between resources/stressors and health outcome. Considering activity/disengagement theory and the selective optimization with compensation model as an example, the integrative potential of the salutogenic model is shown. Finally, the value of the salutogenic model for the fourth age is discussed. Healthy aging is one chance of human existence, but in no way a collective duty that should be imposed on the individual.

    2005-06-01

    The appearance of hair plays an important role in people's overall physical appearance and self-perception. With today's increasing life expectation, the desire to look youthful plays a bigger role than ever. The hair care industry has become aware of this and also more capable to deliver active products that are directed toward meeting this consumer demand. The discovery of pharmacological targets and the development of safe and effective drugs also indicate strategies of the drug industry for maintenance of healthy and beautiful hair. Hair aging comprises weathering of the hair shaft and aging of the hair follicle. The latter manifests as decrease of melanocyte function or graying, and decrease in hair production in androgenetic and senescent alopecia. The scalp is also subject to intrinsic or physiologic aging and extrinsic aging caused by external factors. Intrinsic factors are related to individual genetic and epigenetic mechanisms with interindividual variation. Prototypes are familial premature graying and androgenetic alopecia. Extrinsic factors include ultraviolet radiation and smoking. Experimental evidence supports the hypothesis that oxidative stress plays a role in skin and hair aging. Topical anti-aging compounds for hair include humefactants, hair conditioners, photoprotectors, and antioxidants. Current available treatment modalities with proven efficacy for treatment of androgenetic alopecia are topical minoxidil, oral finasteride, and autologous hair transplantation. In the absence of another way to reverse hair graying, hair colorants are the mainstays of recovering lost hair color. Topical liposome targeting for melanins, genes, and proteins selectively to hair follicles are under current investigation.

    2013-07-01

    Full Text Available There are conflicting results regarding the effect of aging on second-order motion processing (i.e., motion defined by attributes other than luminance, such as contrast. Two studies (Habak & Faubert, 2000; Tang & Zhou, 2009 found that second-order motion processing was more vulnerable to aging than first-order motion processing. Conversely, Billino, Braun, Bremmer and Gegenfurtner (2011 recently found that aging affected first- and second-order motion processing by similar proportions. These three studies used contrast-defined motion as a second-order stimulus, but there can be at least two potential issues when using such a stimulus to evaluate age-related sensitivity losses. First, it has been shown that the motion system processing contrast-defined motion varies depending on the stimulus parameters. Thus, although all these three studies assumed that their contrast-defined motion was processed by a low-level second-order motion system, this was not necessarily the case. The second potential issue is that contrast-defined motion consists in a contrast modulation of a texture rich in high spatial frequencies and aging mainly affects contrast sensitivity at high spatial frequencies. Consequently, some age-related sensitivity loss to second-order motion could be due to a lower sensitivity to the texture rather than to motion processing per se. To avoid these two potential issues, we used a second-order motion stimulus void of high spatial frequencies and which has been shown to be processed by a high-level feature tracking motion system, namely fractal rotation (Lagacé-Nadon, Allard, & Faubert, 2009. We found an age-related deficit on second-order motion processing at all temporal frequencies including the ones for which no age-related effect on first-order motion processing was observed. We conclude that aging affects the ability to track features. Previous age-related results on second-order and global motion processing are discussed in light

    Full Text Available Normal aging of the nervous system is associated with some degree of decline in a number of cognitive functions. With the present day attempts to increase the life span, understanding the metabolic interactions and various mechanisms involved in normal neuronal aging continues to be a challenge. Loss of neurons is now recognized to be more modest than the initial estimates suggested and the loss only affected some of the specific neuroanatomical areas like hippocampus and prefrontal cortex. Individual neurons in addition show reduced size of dendritic and axonal arborization. Neurons have significant homeostatic control of the essential physiological functions like synaptic excitability, gene expression and metabolic regulation. Deviation in these normal events can have severe consequences as observed in aging and neurodegeneration. Based on experimental evidence, the evolution of aging is probably the result of altered metabolic triad: the mitochondria, reactive oxygen species and intracellular calcium homeostasis. Perturbations in the metabolic and functional state of this triad lead to a state of decreased homeostatic reserve, where the aged neurons still could maintain adequate function during normal activity. However, these neurons become vulnerable to the stress of excessive metabolic loads associated with spells of ischemia, trauma progressing to neuronal degeneration. Age-related neuronal dysfunction probably involves a host of subtle changes involving the synapses, receptors, neurotransmitters, cytological alterations, electrical transmission, leading to cognitive dysfunction. An exaggeration of it could be the clinical manifestation of dementia, with intraneuronal accumulation of protein aggregates deranging the metabolic state. This review deals with some of the structural, functional and metabolic features of aging nervous system and discusses briefly the functional consequences.

  14. The age of menarche.

    Rees, M

    1995-01-01

    In females, the first menstrual period, menarche, signals the beginning of the capacity to reproduce and is associated with the development of secondary sexual characteristics. Menarche is one of the most significant milestones in a woman's life. The first cycles tend to be anovulatory and vary widely in length. They are usually painless and occur without warning. Menarche occurs between the ages of 10 and 16 years in most girls in developed countries. Although the precise determinants of menarcheal age remain to be understood, genetic influences, socioeconomic conditions, general health and well-being, nutritional status, certain types of exercise, seasonality, and family size possibly play a role. Over the past century the age at menarche has fallen in industrialized countries, but that trend has stopped and may even be reversing. The average age at menarche in 1840 was 16.5 years, now it is 13. The age at menopause, however, has remained relatively constant at approximately 50 years. The length of time during which women are exposed to endogenous estrogen has therefore been increasing. Reasons for the fall in menarcheal age remain unclear, but one interpretation considers it to be a reflection of the improvement in health and environmental conditions. The decline in menarcheal age appears to be leveling off in many countries such as Britain, Iceland, Italy, Poland, and Sweden, but continues in Germany and some other countries. Late menarche is associated with a decreased risk of developing breast cancer in later life, a decreased frequency of coronary heart disease, later first pregnancy, and reduction in teen pregnancy. Late menarche may, however, be positively associated with the risk of developing Alzheimer's disease.

  15. Embodied Cognition of Aging

    Guillaume T Vallet

    2015-04-01

    Full Text Available Embodiment is revolutionizing the way we consider cognition by incorporating the influence of our body and of the current context within cognitive processing. A growing number of studies which support this view of cognition in young adults stands in stark contrast with the lack of evidence in favor of this view in the field of normal aging and neurocognitive disorders. Nonetheless, the validation of embodiment assumptions on the whole spectrum of cognition is a mandatory step in order for embodied cognition theories to become theories of human cognition. More pragmatically, aging populations represent a perfect target to test embodied cognition theories due to concomitant changes in sensory, motor and cognitive functioning that occur in aging (these theories predict direct interactions between them. Finally, the new perspectives on cognition provided by these theories might also open new research avenues and new clinical applications in the field of aging. The present article aims at showing the value and interest to explore embodiment in normal and abnormal aging as well as introducing some potential theoretical and clinical applications.

    Full Text Available BACKGROUND: Age-related impairments in cognitive functions represent a growing clinical and social issue. Genetic and behavioral characterization of animal models can provide critical information on the intrinsic and environmental factors that determine the deterioration or preservation of cognitive abilities throughout life. METHODOLOGY/PRINCIPAL FINDINGS: Behavior of wild-type, mutant and gamma-irradiated zebrafish (Danio rerio was documented using image-analysis technique. Conditioned responses to spatial, visual and temporal cues were investigated in young, middle-aged and old animals. The results demonstrate that zebrafish aging is associated with changes in cognitive responses to emotionally positive and negative experiences, reduced generalization of adaptive associations, increased stereotypic and reduced exploratory behavior and altered temporal entrainment. Genetic upregulation of cholinergic transmission attenuates cognitive decline in middle-aged achesb55/+ mutants, compared to wild-type siblings. In contrast, the genotoxic stress of gamma-irradiation accelerates the onset of cognitive impairment in young zebrafish. CONCLUSIONS/SIGNIFICANCE: These findings would allow the use of powerful molecular biological resources accumulated in the zebrafish field to address the mechanisms of cognitive senescence, and promote the search for therapeutic strategies which may attenuate age-related cognitive decline.

  17. Hormesis in aging.

    Rattan, Suresh I S

    2008-01-01

    Hormesis in aging is represented by mild stress-induced stimulation of protective mechanisms in cells and organisms resulting in biologically beneficial effects. Single or multiple exposure to low doses of otherwise harmful agents, such as irradiation, food limitation, heat stress, hypergravity, reactive oxygen species and other free radicals have a variety of anti-aging and longevity-extending hormetic effects. Detailed molecular mechanisms that bring about the hormetic effects are being increasingly understood, and comprise a cascade of stress response and other pathways of maintenance and repair. Although the extent of immediate hormetic effects after exposure to a particular stress may only be moderate, the chain of events following initial hormesis leads to biologically amplified effects that are much larger, synergistic and pleiotropic. A consequence of hormetic amplification is an increase in the homeodynamic space of a living system in terms of increased defence capacity and reduced load of damaged macromolecules. Hormetic strengthening of the homeodynamic space provides wider margins for metabolic fluctuation, stress tolerance, adaptation and survival. Hormesis thus counter-balances the progressive shrinkage of the homeodynamic space, which is the ultimate cause of aging, diseases and death. Healthy aging may be achieved by hormesis through mild and periodic, but not severe or chronic, physical and mental challenges, and by the use of nutritional hormesis incorporating mild stress-inducing molecules called hormetins. The established scientific foundations of hormesis are ready to pave the way for new and effective approaches in aging research and intervention.

    Full Text Available Biological psychological and social determinants of old age: Bio-psycho-social aspects of human aging. The aging of humans is a physiological and dynamic process ongoing with time. In accordance with most gerontologists’ assertions it starts in the fourth decade of life and leads to death. The process of human aging is complex and individualized, occurs in the biological, psychological and social sphere. Biological aging is characterized by progressive age-changes in metabolism and physicochemical properties of cells, leading to impaired self-regulation, regeneration, and to structural changes and functional tissues and organs. It is a natural and irreversible process which can run as successful aging, typical or pathological. Biological changes that occur with age in the human body affect mood, attitude to the environment, physical condition and social activity, and designate the place of seniors in the family and society. Psychical ageing refers to human awareness and his adaptability to the ageing process. Among adaptation attitudes we can differentiate: constructive, dependence, hostile towards others and towards self attitudes. With progressed age, difficulties with adjustment to the new situation are increasing, adverse changes in the cognitive and intellectual sphere take place, perception process involutes, perceived sensations and information received is lowered, and thinking processes change. Social ageing is limited to the role of an old person is culturally conditioned and may change as customs change. Social ageing refers to how a human being perceives the ageing process and how society sees it.

    In a previous field-based study, how old one looks for one's age (perceived age) was found to be predictive of mortality in elderly individuals. In conjunction, perceived age is of relevance and interest to the layperson. Here, a clinical methodology for generating perceived age as a biomarker...... of facial ageing is detailed. The methodology utilises facial photographs of subjects to present images to large numbers of age assessors who are primarily nationals of the country of study origin. In five observational studies in five different countries involving 874 female subjects it was found...... that subject age and assessor gender, nationality, age and ageing expertise had little effect on the perceived age data generated. However, increasing the numbers of age assessors up to 50 substantially increased the reproducibility of the mean perceived age for an image and a minimum of 10 assessors were...

    A new family classification, based on a catalog of proper elements with $\\sim 384,000$ numbered asteroids and on new methods is available. For the $45$ dynamical families with $>250$ members identified in this classification, we present an attempt to obtain statistically significant ages: we succeeded in computing ages for $37$ collisional families. We used a rigorous method, including a least squares fit of the two sides of a V-shape plot in the proper semimajor axis, inverse diameter plane to determine the corresponding slopes, an advanced error model for the uncertainties of asteroid diameters, an iterative outlier rejection scheme and quality control. The best available Yarkovsky measurement was used to estimate a calibration of the Yarkovsky effect for each family. The results are presented separately for the families originated in fragmentation or cratering events, for the young, compact families and for the truncated, one-sided families. For all the computed ages the corresponding uncertainties are pro...

    The Department of Energy and its three weapons laboratories (LANL, LLNL, and SNL) have developed a Stockpile Stewardship and Management Program (SSMP) in response to their designated mission of maintaining an effective, i.e. reliable and safe, nuclear deterrent without underground nuclear tests (UGTs). The need to ensure the effectiveness of an aging stockpile presents new challenges of major importance. In this study we review what is known about the aging of critical constituents, particularly the high explosives, polymers, and metals in the enduring stockpile. We discuss data that are required to provide a fuller understanding of aging, and how to obtain that data as a basis for anticipating and addressing potential stockpile problems. Our particular concern is problems that may arise in the short term, i.e. within the next 5 to 10 years, and their implied requirements for preventive maintenance and remanufacture.

  4. Redox theory of aging.

    Jones, Dean P

    2015-08-01

    Metazoan genomes encode exposure memory systems to enhance survival and reproductive potential by providing mechanisms for an individual to adjust during lifespan to environmental resources and challenges. These systems are inherently redox networks, arising during evolution of complex systems with O2 as a major determinant of bioenergetics, metabolic and structural organization, defense, and reproduction. The network structure decreases flexibility from conception onward due to differentiation and cumulative responses to environment (exposome). The redox theory of aging is that aging is a decline in plasticity of genome-exposome interaction that occurs as a consequence of execution of differentiation and exposure memory systems. This includes compromised mitochondrial and bioenergetic flexibility, impaired food utilization and metabolic homeostasis, decreased barrier and defense capabilities and loss of reproductive fidelity and fecundity. This theory accounts for hallmarks of aging, including failure to maintain oxidative or xenobiotic defenses, mitochondrial integrity, proteostasis, barrier structures, DNA repair, telomeres, immune function, metabolic regulation and regenerative capacity.

    1991-09-01

    'Ageing is a multistep, multifaceted, time-dependent phenomenon characterized by the decreased ability of a system to respond to exogenous and endogenous stress from either physical, chemical or biologic agents'. Cutaneous ageing provides a visible model of the interaction between endogenous (intrinsic) factors and exogenous (extrinsic) factors. In skin, the principal extrinsic-factor is ultraviolet light (UV) which is responsible for the constellation of changes termed photoageing. In recent years, much interest has been directed towards defining the ageing processes in skin and excellent comprehensive reviews have been compiled. This review aims to highlight several areas of developing knowledge, and focuses on the potential importance of environmental changes as they influence skin ageing and carcinogenesis. Repeated reference to the effects of UV on the skin are inevitable in any review of skin ageing and this is scarcely surprising as the skin contains many cells as well as subcellular and extracellular chromophores which are capable of absorbing energy within the UV spectrum. Cellular chromophores include among others keratinocytes, melanocytes, Langerhans cells, dermal fibroblasts and mast cells. Subcellular chromophores include keratin, melanin, collagen, elastin and a number of proteins, lipids and steroids (such as vitamin D). Urocanic acid, a photoisomerization product of the amino-acid histidine, may provide some limited photoprotection and some believe it to be important in UV induced immunosuppression. Understanding events at the molecular and biochemical level has unfortunately not been paralleled by clinical advances and the common, troublesome skin-problems of old age such as cancer, xerosis and pruritus remain a major cause of morbidity and yet are poorly explained.

    Full Text Available The changing social scenario together with economic growth and an increase in job opportunities has to a great extent reduced gender inequality and has resulted in more and more older women seeking help from infertility clinics. Fertility and aging have always been closely linked and the age of the female partner remains the single most important factor in predicting success with treatment. Although tests for the ovarian reserve are an important informative tool and are helpful in selecting treatment options, they are poor predictors of the outcome.

    The paper shows the importance of serendipity and exaptation in selected key moments of ageing research and argue that rationalistic dominant models in scientific research have masked the importance of reverse models of discovery based on serendipity and exaptation. I ask why this is the case and analyze three contributing factors: unprestatability of the functions of technologies, multidimensionality and astronomical complexity of the space over which biological reactions occurs and role of scientific paradigms in channeling research toward incrementalism. Empirical evidence of the limits of the rationalistic models are presented next. I close the paper by discussing the implications for aging research.

  16. Aging and the intestine

    Institute of Scientific and Technical Information of China (English)

    Laurie Drozdowski; Alan BR Thomson

    2006-01-01

    Over the lifetime of the animal, there are many changes in the function of the body's organ systems. In the gastrointestinal tract there is a general modest decline in the function of the esophagus, stomach, colon,pancreas and liver. In the small intestine, there may be subtle alterations in the intestinal morphology, as well as a decline in the uptake of fatty acids and sugars.The malabsorption may be partially reversed by aging glucagon-like peptide 2 (GLP2) or dexamethasone.Modifications in the type of lipids in the diet will influence the intestinal absorption of nutrients: for example, in mature rats a diet enriched with saturated as compared with polysaturated fatty acids will enhance lipid and sugar uptake, whereas in older animals the opposite effect is observed. Thus, the results of studies of the intestinal adaptation performed in mature rats does not necessarily apply in older animals. The age-associated malabsorption of nutrients that occurs with aging may be one of the several factors which contribute to the malnutrition that occurs with aging.

    2001-01-01

    The prolongation of life expectancy and the drastic reduction of fertility rate are the primary cause of an aging world. It is projected that the elderly (above 65) will increase within the next 25 years by 82 %, whereas the new born only by 3 %. Despite the enormous medical progress during the past few decades, the last years of life are still accompanied by increasing ill health and disability. The ability to maintain active and independent living for as long as possible is a crucial factor for aging in health and dignity. Therefore, the promotion of healthy aging and the prevention of disability in men, must assume a central role in medical research and medical practice as well as in the formulation of national health and social policies. Effective programs promoting health and aging will ensure a more efficient use of health and social services and improve the quality of life in older persons by enabling them to remain independent and productive. The most important and drastic gender differences in aging are related to organs and or systems dependant or influenced by reproductive hormones. In distinction to the course of reproductive aging in women, with the rapid decline in sex hormones and expressed by the cessation of menses, aging men experience a slow and continuous decline of hormones. This decline in endocrine function involves: A decrease of testosterone, dehydroepiandrosterone (DHEA),oestrogens, thyroid stimulating hormone (TSH), growth hormone (GH), insulin-like growth factor-1 (IGF-1), and melatonin. This decrease is concomitant with an increase of LH and FSH. In addition sex hormone binding globulin's (SHBG) increase with age resulting in further lowering the concentrations of free biologically active androgens. Interventions such as hormone replacement therapy may prevent, delay or alleviate the debilitating conditions which may result from secondary partial endocrine deficiency. Primary and secondary preventive strategies such as the promotion of

    In an increasingly aging society, age has become a foundational dimension of social grouping broadly targeted by advertising and governmental policies. However, perception of old age induces mainly strong negative social biases. To characterize their cognitive and perceptual foundations, we modeled the mental representations of faces associated with three age groups (young age, middle age, and old age), in younger and older participants. We then validated the accuracy of each mental representation of age with independent validators. Using statistical image processing, we identified the features of mental representations that predict perceived age. Here, we show that whereas younger people mentally dichotomize aging into two groups, themselves (younger) and others (older), older participants faithfully represent the features of young age, middle age, and old age, with richer representations of all considered ages. Our results demonstrate that, contrary to popular public belief, older minds depict socially relevant information more accurately than their younger counterparts.

    This report presents a description of the trends in growth of the elderly population in the Philippines and their health, disability, education, work status, income, and family support. The proportion of elderly in the Philippines is much smaller than in other Southeast Asian countries, such as Singapore and Malaysia. The elderly population aged over 65 years increased from 2.7% of total population in 1990 to 3.6% in 1990. The elderly are expected to comprise 7.7% of total population in 2025. The proportion of elderly is small due to the high fertility rate. Life expectancy averages 63.5 years. The aged dependency ratio will double from 5.5 elderly per 100 persons aged 15-64 years in 1990 to 10.5/100 in 2025. A 1984 ASEAN survey found that only 11% of elderly rated their health as bad. The 1990 Census reveals that 3.9% were disabled elderly. Most were deaf, blind, or orthopedically impaired. 16% of elderly in the ASEAN survey reported not seeing a doctor even when they needed to. 54% reported that a doctor was not visited due to the great expense. In 1980, 67% of men and 76% of women aged over 60 years had less than a primary education. The proportion with a secondary education in 2020 is expected to be about 33% for men and 33% for women. 66.5% of men and 28.5% of women aged over 60 years were in the formal labor force in 1990. Women were less likely to receive cash income from current jobs or pensions. 65% of earnings from older rural people was income from agricultural production. 60% of income among urban elderly was from children, and 23% was from pensions. Family support is provided to the elderly in the form of coresidence. In 1988, 68% of elderly aged over 60 years lived with at least one child. Retirement or nursing homes are uncommon. The Philippines Constitution states that families have a duty to care for elderly members.

    The aging of humans is a physiological and dynamic process ongoing with time. In accordance with most gerontologists' assertions it starts in the fourth decade of life and leads to death. The process of human aging is complex and individualized, occurs in the biological, psychological and social sphere. Biological aging is characterized by progressive age-changes in metabolism and physicochemical properties of cells, leading to impaired self-regulation, regeneration, and to structural changes and functional tissues and organs. It is a natural and irreversible process which can run as successful aging, typical or pathological. Biological changes that occur with age in the human body affect mood, attitude to the environment, physical condition and social activity, and designate the place of seniors in the family and society. Psychical ageing refers to human awareness and his adaptability to the ageing process. Among adaptation attitudes we can differentiate: constructive, dependence, hostile towards others and towards self attitudes. With progressed age, difficulties with adjustment to the new situation are increasing, adverse changes in the cognitive and intellectual sphere take place, perception process involutes, perceived sensations and information received is lowered, and thinking processes change. Social ageing is limited to the role of an old person is culturally conditioned and may change as customs change. Social ageing refers to how a human being perceives the ageing process and how society sees it.

  17. Constipation in old age.

    LENUS (Irish Health Repository)

    2009-01-01

    The prevalence of constipation increases with age. However, constipation is not a physiological consequence of normal ageing. Indeed, the aetiology of constipation in older people is often multifactorial with co-morbid diseases, impaired mobility, reduced dietary fibre intake and prescription medications contributing significantly to constipation in many instances. A detailed clinical history and physical examination including digital rectal examination is usually sufficient to uncover the causes of constipation in older people; more specialized tests of anorectal physiology and colonic transit are rarely required. The scientific evidence base from which to develop specific treatment recommendations for constipation in older people is, for the most part, slim. Constipation can be complicated by faecal impaction and incontinence, particularly in frail older people with reduced mobility and cognitive impairment; preventative strategies are important in those at risk.

  18. Stellar ages from asteroseismology

    Lebreton, Yveline

    2008-01-01

    Asteroseismology provides powerful means to probe stellar interiors. The oscillations frequencies are closely related to stellar interior properties via the density and sound speed profiles. Since these are tightly linked with the mass and evolutionary state, we can expect to determine the age and mass of a star from the comparison of its oscillation spectrum with predictions of stellar models. Such a comparison suffers both from the problems we face when modeling a particular star (as the uncertainties on global parameters and chemical composition) and from our misunderstanding of processes at work in stellar interiors (as the transport processes that may lead to core mixing and affect the model ages). For stars where observations have provided precise and numerous oscillation frequencies together with accurate global parameters and additional information (as the radius or the mass if the star is in a binary system, the interferometric radius or the mean density if the star is an exoplanet host), we can also...

    Full Text Available Face is the important feature of the human beings. We can derive various properties of a human by analyzing the face. The objective of the study is to design a classifier for age using facial images. Age classification is essential in many applications like crime detection, employment and face detection. The proposed algorithm contains four phases: preprocessing, feature extraction, feature selection and classification. The classification employs two class labels namely child and Old. This study addresses the limitations in the existing classifiers, as it uses the Grey Level Co-occurrence Matrix (GLCM for feature extraction and Support Vector Machine (SVM for classification. This improves the accuracy of the classification as it outperforms the existing methods.

    A technique for distinguishing adult from yearling wild mallards (Anas platyrhynchos), from late winter through the nesting season, was developed by applying discriminant analysis procedures to selected wing feather characters of 126 yearlings and 76 adults (2-year-olds) hand-reared from wild eggs during 1974, 1975, and 1977. Average values for feather characters generally increased as the birds advanced from yearlings to adults. Black-white surface area of greater secondary covert 2 was the single most reliable aging character identified during the study. The error rate was lowest in females (3%) when discriminant functions were used with measurements of primary 1 weight and black-white area of greater secondary covert 2 and in males (9%) when the functions were used with black-white area of greater secondary coverts 1, 2, and 3. Methodology precludes aging of birds in the field during capture operations.

    Full Text Available Russian historiography in recent decades, there has been increased interest in the problems of everyday life in different historical periods and epochs. Regarding the middle ages and new time, an integral part of everyday life was the belief in the struggle between God and Devil, and Man in this confrontation was one of the conflicting parties. Holy Inquisition has been fighting with the followers of dark forces, witches and apostates – heretics since the XIII century. However, special attention should be paid to the fact that in addition to the above-mentioned victims of the ecclesiastical court, become and other devil's servants are werewolves. An important point is that the belief in creatures that can change their appearance, one way or another is present in all peoples of the world, but the massive scale, amounting to hysteria, she gets in Europe. According to the results of the research, the authors note that theories and facts that shaped the consciousness of man at the crossroads of two historical epochs – the middle ages and modern times, under the influence of Church ideologues and demonic studies, as well as reasoning of the average man which has been formed through the prism of perception of that time, belief in werewolves firmly occupies its own niche in daily life for a long time.

    Space age had its world premiere at the large-screen Spaceport Theater at Cape Canaveral/Kennedy Spaceport. The first program was screened for invited guests who, that morning, also witnessed a launch of the Space Shuttle. Since that mission carried the first Japanese astronaut, it was a nice tie-in to the substantial co-production participation of space age by NHK Japan. A special press conference for the series and a twenty-minute preview reel was screened for journalists who were also at the Cape for the shuttle launch. Numerous first-hand newspaper articles were generated. CNN ran part of the preview reel. The first episode in the series, `The Quest for Planet Mars,` then ran twice a day for a week, prior to the Public Broadcasting Service broadcast on an Imax format screen at the Spaceport theater. The program was seen by thousands of visitors. Space age also had a special premier at the National Academy of Sciences in Washington, DC with some 400 special guests, including scientists and government agency representatives.

  5. Old age and poverty

    Full Text Available The process of demographic changes in Serbia is followed by discussions on the need to provide safety at old age and solve the problems of poverty and social exclusion of older citizens. In the current state there are no mechanisms that guarantee an adequate life standard at old age, the consequence of which is a high poverty rate, deteriorating health and limited access to social programs. The results of the Survey on life standard from 2002 and 2007 show that poverty among population in general and pensioners has decreased, while the poverty risk among people older than 65 has increased twice. The restrictive methods of the reforms cause a change in the relation between the pensions and the earnings, so that more and more pensioners receive below average, i.e. minimal pensions. Not all old people are covered by pension insurance so that a significant number (around 400.000 does not have a safe monthly income at all. The state program of financial aid is of modest size and does not provide help to all of the poor. Welfare aid decreases the risk of poverty, but it do not guarantee an adequate level of material security at old age. The low level of minimal and average pensions, the decline of participation in the average earnings and the strict criteria of the social security system have brought to awareness the necessity of 'social pensions' and various help and support programs for the elderly. .

    Age is the most important risk factor for tumorigenesis. More than 60% of new cancers and more than 70% of cancer deaths occur in elderly subjects >65 years. The immune system plays an important role in the battle of the host against cancer development. Deleterious alterations occur to the immune response with aging, termed immunosenescence. It is tempting to speculate that this waning immune response contributes to the higher incidence of cancer, but robust data on this important topic are few and far between. This review is devoted to discussing state of the art knowledge on the relationship between immunosenescence and cancer. Emerging understanding of the aging process at the molecular level is viewed from the perspective of this increased tumorigenesis. We also consider some of the most recent means to intervene in the modulation of immunosenescence to increase the ability of the immune system to fight against tumors. Future research will unravel new aspects of the immune response against tumors which will be modulable to decrease the burden of cancer in elderly individuals.

    Full Text Available With an increasing life expectancy and a decreasing reproduction rate, the population structure changes. A Jenapharm R & D program investigates the endocrinology of aging men. In men, a decrease in production of sex steroids and other hormones with age can be observed. The typical patterns of daily rhythmicity become less distinct. This is part of a very complex picture in which not only isolated hormones are involved, but also the influence of hormones on each other. Many factors from the external and intemal environment mediated by neurotransmitters constantly affect the highly sensitive hormonal balance. Therefore, aging has also been defined as "the gradual dysfunction of homeostatic processes". Declining testosterone (T levels are involved in 'andropausal' symptoms in men: loss of libido, erectile dysfunction, insulin receptor resistance, obesity, osteoporosis, disturbances of lipid metabolism, myocardial and circulatory disturbances, impaired well-being and mood. Data are derived from studies in hypogonadal men treated by T replacement. In such parients under T treatment libido increases, fat mass decreases, muscle strenth, bone mineral density and erythropoesis increase. Whether the symptoms of andropause in aging men could successfully be treated by T substitution remains to be investigated. Negative effects of T, especially on the prostate and the cardiovascular system, are under discussion. There is increasing evidence that low T levels seem to be a risk factor for both the prostate and the cardiovascular system. Jenapharm's new testosterone undecanoate formulation for intramuscular injection can be administered every three months. T levels remain within the physiologic range. No supraphysiologic peaks occur. In women, estrogens have beneficial non-genital effects. Studies concentrate on synthetic estrogens for men without feminizing properties such as gynecomastia and reduced testicular size.

  9. Age aspects of habitability

    2016-04-01

    A `habitable zone' of a star is defined as a range of orbits within which a rocky planet can support liquid water on its surface. The most intriguing question driving the search for habitable planets is whether they host life. But is the age of the planet important for its habitability? If we define habitability as the ability of a planet to beget life, then probably it is not. After all, life on Earth has developed within only ~800 Myr after its formation - the carbon isotope change detected in the oldest rocks indicates the existence of already active life at least 3.8 Gyr ago. If, however, we define habitability as our ability to detect life on the surface of exoplanets, then age becomes a crucial parameter. Only after life had evolved sufficiently complex to change its environment on a planetary scale, can we detect it remotely through its imprint on the atmosphere - the so-called biosignatures, out of which the photosynthetic oxygen is the most prominent indicator of developed (complex) life as we know it. Thus, photosynthesis is a powerful biogenic engine that is known to have changed our planet's global atmospheric properties. The importance of planetary age for the detectability of life as we know it follows from the fact that this primary process, photosynthesis, is endothermic with an activation energy higher than temperatures in habitable zones, and is sensitive to the particular thermal conditions of the planet. Therefore, the onset of photosynthesis on planets in habitable zones may take much longer time than the planetary age. The knowledge of the age of a planet is necessary for developing a strategy to search for exoplanets carrying complex (developed) life - many confirmed potentially habitable planets are too young (orbiting Population I stars) and may not have had enough time to develop and/or sustain detectable life. In the last decade, many planets orbiting old (9-13 Gyr) metal-poor Population II stars have been discovered. Such planets had had

  13. Evolutionary theories of aging can explain why we age.

    Science.gov (United States)

    Le Bourg, Eric

    2014-01-01

    Evolutionary theories of aging explain why we age. These theories take into account the fact that, in the wild, mean lifespan of many species is usually shorter than it could be in protected environments. In such conditions, because most of animals die before reaching old age, there is no selection in favor or against alleles with effects at old age. Alleles with negative effects at this age can thus accumulate in successive generations, particularly if they also have positive effects at young age and are thus retained by selection. This chapter describes the evolutionary theories of aging and their consequences for the understanding of the biology of aging as well as the challenges to these theories. It is argued that these theories offer a reasonable explanation to the existence of the aging process even if they can surely be refined.

    While recognition of most facial variations, such as identity, expression and gender, has been extensively studied, automatic age estimation has rarely been explored. In contrast to other facial variations, aging variation presents several unique characteristics which make age estimation a challenging task. This paper proposes an automatic age estimation method named AGES (AGing pattErn Subspace). The basic idea is to model the aging pattern, which is defined as the sequence of a particular individual' s face images sorted in time order, by constructing a representative subspace. The proper aging pattern for a previously unseen face image is determined by the projection in the subspace that can reconstruct the face image with minimum reconstruction error, while the position of the face image in that aging pattern will then indicate its age. In the experiments, AGES and its variants are compared with the limited existing age estimation methods (WAS and AAS) and some well-established classification methods (kNN, BP, C4.5, and SVM). Moreover, a comparison with human perception ability on age is conducted. It is interesting to note that the performance of AGES is not only significantly better than that of all the other algorithms, but also comparable to that of the human observers.

    The importance of bone loss with aging increases year by year. When Bismarck set the age of retirement at 65, it did not cost Prussia much because few lived to receive pensions. At the turn of the century, only 4.1 per cent of our population was 65 or older. But the present change in demography, called "The Graying of America," means that we now have 13 per cent of the population 65 or older: 35 million people, 20 million women and 15 million men. For the women who are now passing through menopause or who have had oophorectomies, the predictable deformities caused by fractures of the vertebrae, wrists, and hips will make up the single largest cause of hospitalization unless prophylaxis against postmenopausal bone loss is instituted. The best established prophylaxis is now low-dose estrogen-gestagen replacement therapy. Very promising is the combination of very-low-dose estrogen and high-dose oral calcium supplements (Fig. 17). For women who cannot or will not take estrogens, certain progestational agents offer equal protection to bone, though, of course, these agents do not protect against atrophy of the other target organs, most notably the vaginal mucosa.

    Aging is characterized by an increase in relative population of 65 years and older, and can say that, in our country, it is a phenomenon demographic, political, social and health. Several studies have shown that the nutritional status of the general population and the elderly, in particular, is a valid indicator to predict longevity and quality of life of this group of people. The World Health Organization (who) pointed out that the elderly population is a group nutritionally very vulnerable as a result of anatomical and physiological changes associated with aging. Between 35-40 of the elderly has some kind of altered nutrition or malnutrition: protein or protein-energy malnutrition, selective deficiency of vitamins and minerals, inadequate water intake, obesity, etc. The best way to promote the quality of life and prevent disease is a proper diet, also called healthy eating, adapted to the special circumstances which older persons may present without forgetting gastronomy is not incompatible with health. In this article, some tips are also available for preparing and cooking food, as well as culinary strategies to introduce them in the daily menu.

    Age-related macular degeneration (ARMD) is a multifactorial disease caused by a combination of genetic and environmental factors. It is the first cause of blindness in patients over 50 in the western world. The disease has been traditionally classified into early and late stages with dry (atrophic) and wet (neovascular) forms: neovascular form is characterized by new blood vessels development under the macula (choroidal neovascularisation) which lead to a rapid decline of vision associated with metamorphopsia and requiring an urgent ophtalmological examination. Optical coherence tomography is now one of the most important part of the examination for diagnosis and treatment. Patient with age related maculopathy should consider taking a dietary supplement such that used in AREDS. The treatment of the wet ARMD has largely beneficied since year 2006 of anti-VEGF (vascular endothelial growth factor) molecules such as ranibizumab or bevacizumab given as repeated intravitreal injections. A systematic follow up each 4 to 8 week in required for several years. There is no effective treatment at the moment for dry AMD. For patients with binocular visual acuity under 60/200 rehabilitation includes low vision specialist, vision aids and psychological support.

    The present study was aimed at comparing the judgment capacities manifested by young adults, middle-aged adults, and elderly people in an everyday life setting implying the consideration of direct as well as inverse relationships between the cues and the criterion. The chosen situation was borrowed from elementary physics and concerned the relationships between mass, volume and density. In forming their estimations of mass, all elderly people were able to use volume and density information. In addition, most of them were able to combine these pieces of information in a correct, multiplicative way. In forming their estimations of volume, all elderly people were able to use mass and density information but a majority of them used the density information in a direct way. By contrast, most young and middle-aged adults correctly used the density information in an inverse way. The findings strengthen and extend the case made by Chasseigne et al. [Acta Psychologica 97 (1997) 235] as regards the trouble elderly people face in using inverse relationships in a judgment situation. The difficulty elderly people face is not confined to learning settings. It may also be observed in ecological, non-learning environments, where the relationships considered do not entirely depend on the experimenter's choice.

    The cultural and social contexts of aging have changed a great deal during the last two decades and aging experiences have become more differentiated. However, pervasive age stereotypes still exist that limit the agency and self-perception of older people, and part of the experience of new aging is to actively combat such negative stereotypes. The purpose of this study is to explore how lifelong learning and a degree attainment in midlife become embedded into new aging practices. The study will focus on a specific group of aging workers who attained a Master's degree from Finnish universities in their fifties. In order to better understand the aging experiences of these older graduates, this study seeks to address how they construct the meaning of aging in relation to their own educational and professional status. The data consist of 14 life-history interviews, which were analyzed as narrative identity performances. Differentiating oneself from the stereotype of physical and mental decline and positioning oneself in a favorable way in inter-generational relations were common ways of approaching aging. Age-negotiation and ambivalence about aging were expressed by structuring narratives around clear oppositions and contradictions. University studies at age 50+ became a talking point in countering cultural age-stereotypes, because it showed that aging workers could still accomplish significant goals and "renew" oneself intellectually. University studies also enabled collaboration with the younger generation and the breaking of narrow age boundaries.

    OBJECTIVE: To determine whether perceived age correlates with survival and important age related phenotypes. DESIGN: Follow-up study, with survival of twins determined up to January 2008, by which time 675 (37%) had died. SETTING: Population based twin cohort in Denmark. PARTICIPANTS: 20 nurses, 10...... was significantly associated with survival, even after adjustment for chronological age, sex, and rearing environment. Perceived age was still significantly associated with survival after further adjustment for physical and cognitive functioning. The likelihood that the older looking twin of the pair died first...... age, controlled for chronological age and sex, also correlated significantly with physical and cognitive functioning as well as with leucocyte telomere length. CONCLUSION: Perceived age-which is widely used by clinicians as a general indication of a patient's health-is a robust biomarker of ageing...

    Age-related changes in mitochondria are associated with decline in mitochondrial function. With advanced age, mitochondrial DNA volume, integrity and functionality decrease due to accumulation of mutations and oxidative damage induced by reactive oxygen species (ROS). In aged subjects, mitochondria are characterized by impaired function such as lowered oxidative capacity, reduced oxidative phosphorylation, decreased ATP production, significant increase in ROS generation, and diminished antioxidant defense. Mitochondrial biogenesis declines with age due to alterations in mitochondrial dynamics and inhibition of mitophagy, an autophagy process that removes dysfunctional mitochondria. Age-dependent abnormalities in mitochondrial quality control further weaken and impair mitochondrial function. In aged tissues, enhanced mitochondria-mediated apoptosis contributes to an increase in the percentage of apoptotic cells. However, implementation of strategies such as caloric restriction and regular physical training may delay mitochondrial aging and attenuate the age-related phenotype in humans.

  10. Gender, aging, and the economics of "active aging": Setting a new research agenda.

    The world is aging, and the percentages of older people are on a dramatic ascent. This dramatic demographic aging of human society is not gender neutral; it is mostly about older women. One of the key policy approaches to address the aging revolution is known as "active aging," crystalized by the WHO in 2002 by three pillars: participation, health, and security. The active aging policy has financial and economic aspects and affects both men and women. However, as argued in this article, a gender-based approach has not been adopted within the existing active aging framework. Therefore, a new gender-specific research agenda is needed, one that focuses on an interrelation between gender and different economic aspects of "active aging" from international, comparative, cultural, and longitudinal perspectives.

    Full Text Available Background: Growth can be one of the most uncertain variations, but understanding the same is very important for diagnosis and treatment planning. Skeletal age and dental age have been used to determine a child′s developmental age. Several researchers have evaluated the association between dental and skeletal maturity with chronologic age on different population. The purpose of the present study was to find out whether dental age estimation can be replaced for skeletal age estimation in the Dakshina Kannada population. Methods: A total of 104 samples equally distributed among both genders in the age group of 9-14 years were selected. Skeletal age was estimated using hand-wrist radiographs and Fishman′s skeletal maturation index and dental age was measured using Demirjian′s method. Results: Spearman′s rank-order correlation coefficients were used to measure the association between the skeletal maturity and dental maturity. The mean ages of male and female samples were determined as 11.89 ± 1.867 years and 12.21 ± 1.473 years, respectively. Chronological age was found to be positively correlated to dental age and skeletal age and found to be statistically significant (P < 0.01. The correlation between dental age and skeletal age was also found to be statistically significant with P < 0.001 and correlation coefficient of 0.683 and 0.704 for males and females. Conclusion: The present study showed a strong relation between the developmental ages in mixed dentition population; hence, dental age can be considered as a replacement in the study population.

  12. Modeled ground water age distributions

    2009-01-01

    The age of ground water in any given sample is a distributed quantity representing distributed provenance (in space and time) of the water. Conventional analysis of tracers such as unstable isotopes or anthropogenic chemical species gives discrete or binary measures of the presence of water of a given age. Modeled ground water age distributions provide a continuous measure of contributions from different recharge sources to aquifers. A numerical solution of the ground water age equation of Ginn (1999) was tested both on a hypothetical simplified one-dimensional flow system and under real world conditions. Results from these simulations yield the first continuous distributions of ground water age using this model. Complete age distributions as a function of one and two space dimensions were obtained from both numerical experiments. Simulations in the test problem produced mean ages that were consistent with the expected value at the end of the model domain for all dispersivity values tested, although the mean ages for the two highest dispersivity values deviated slightly from the expected value. Mean ages in the dispersionless case also were consistent with the expected mean ages throughout the physical model domain. Simulations under real world conditions for three dispersivity values resulted in decreasing mean age with increasing dispersivity. This likely is a consequence of an edge effect. However, simulations for all three dispersivity values tested were mass balanced and stable demonstrating that the solution of the ground water age equation can provide estimates of water mass density distributions over age under real world conditions.

  15. How old do you feel? The role of age discrimination and biological aging in subjective age.

    Directory of Open Access Journals (Sweden)

    Yannick Stephan

    Full Text Available Subjective age, or how young or old individuals experience themselves to be relative to their chronological age, is a crucial construct in gerontology. Subjective age is a significant predictor of important health outcomes, but little is known about the criteria by which individuals' subjectively evaluate their age. To identify psychosocial and biomedical factors linked to the subjective evaluation of age, this study examined whether perceived age discrimination and markers of biological aging are associated with subjective age. Participants were 4776 adults (Mage = 68 from the 2008 and 2010 waves of the Health and Retirement Study (HRS who completed measures of subjective age, age discrimination, demographic variables, self-rated health and depression, and had physical health measures, including peak expiratory flow, grip strength, waist circumference, systolic and diastolic blood pressure. Telomere length was available for a subset of participants in the 2008 wave (n = 2214. Regression analysis indicated that perceived age discrimination, lower peak expiratory flow, lower grip strength, and higher waist circumference were associated with an older subjective age, controlling for sociodemographic factors, self-rated health, and depression. In contrast, blood pressure and telomere length were not related to subjective age. These findings are consistent with the hypothesis that how old a person feels depends in part on psychosocial and biomedical factors, including the experiences of ageism and perceptible indices of fitness and biological age.

  16. Xerostomia in the aged.

    Navazesh, M

    1989-01-01

    Xerostomia is a symptom associated with a variety of causes. Disorders in the production and transport as well as excessive depletion of saliva may lead to xerostomia. It is difficult to make any general statement about the functional significance of salivary gland changes associated with aging, as the clinical evidence is controversial and data from different studies do not encourage any uniform conclusion. Rational treatments of xerostomias may be performed casually (for example, withdrawal or exchange of drugs inhibiting salivary secretion), but will often only be practical as a symptomatic therapy. Special attention should be directed toward maintenance of adequate oral hygiene in order to prevent clinical complications such as increased dental caries, monilial infection, dysgeusia and tooth sensitivity, which are associated with xerostomia and are often observed in elderly xerostomic patients.

    1993-06-01

    With the average life duration becoming longer there is an increasing number of old people in the population. In the literature the problem of old people is still neglected. The most visible changes in old people occur in physical characteristics and functions; at first a change in psychological functions was also reported to take place. However, it was shown that results depended to a great extent on the method used: the longitudinal method (following up one and the same generation) frequently gave rather different and much better results than the cross-sectional method. The question of old age and working abilities is an important one. Certain positive personality traits seem to compensate for a drop in certain abilities. In the modern automated industry time pressure and adaptation to new working conditions are a handicap for the elderly, but the application of different ergonomic principles can greatly improve the situation.

  18. Reconditioning aging muscles.

    Science.gov (United States)

    Kraus, H

    1978-06-01

    Weakness or stiffness of key posture muscles can cause much of the disability seen in elderly patients. Too much tension and too little exercise greatly increase the natural loss of muscular fitness with age. A systematic program of exercise, stressing relaxation and stretching of tight muscles and strenghthening of weak muscles, can improve physical fitness. The program must be tailored to the patient, starting with relaxation and gentle limbering exercises and proceeding ultimately to vigorous muscle-stretching exercises. Muscle aches and pain from tension and muscle imbalance are to be expected. Relaxation relieves tension pain, and strengthening weak muscles and stretching tight muscles will correct muscle imbalance. To prevent acute muscle spasm, the patient should avoid excessive exertion and increase exercise intensity gradually.

    The ISS External Survey integrates the requirements for photographic and video imagery of the International Space Station (ISS) for the engineering, operations, and science communities. An extensive photographic survey was performed on all Space Shuttle flights to the ISS and continues to be performed daily, though on a level much reduced by the limited available imagery. The acquired video and photo imagery is used for both qualitative and quantitative assessments of external deposition and contamination, surface degradation, dynamic events, and MMOD strikes. Many of these assessments provide important information about ISS surfaces and structural integrity as the ISS ages. The imagery is also used to assess and verify the physical configuration of ISS structure, appendages, and components.

    Full Text Available China has the largest population of elderly adults. Meanwhile, it is one of the countries showing fastest aging speed in the world. Aging processing is always companied with a series of brain structural and functional changes, which result in the decline of processing speed, working memory, long-term memory and executive function, etc. The studies based on functional magnetic resonance imaging (fMRI found certain aging effects on brain function activation, spontaneous activity and functional connectivity in old people. However, few studies have explored the brain functional curve during the aging process while most previous studies explored the differences in the brain function between young people and old people. Delineation of the human brain functional aging curve will promote the understanding of brain aging mechanisms and support the normal aging monitoring and early detection of abnormal aging changes. doi: 10.3969/j.issn.1672-6731.2014.03.005

    2016-01-01

    Research on successful aging at work has neglected contextual resources such as organizational climate, which refers to employees' shared perceptions of their work environment. We introduce the construct of organizational climate for successful aging (OCSA) and examine it as a buffer of the negative relationship between employee age and focus on opportunities (i.e., beliefs about future goals and possibilities at work). Moreover, we expected that focus on opportunities, in turn, positively predicts job satisfaction, organizational commitment, and motivation to continue working after official retirement age. Data came from 649 employees working in 120 companies (M age = 44 years, SD = 13). We controlled for organizational tenure, psychological climate for successful aging (i.e., individuals' perceptions), and psychological and organizational age discrimination climate. Results of multilevel analyses supported our hypotheses. Overall, our findings suggest that OCSA is an important contextual resource for successful aging at work.

    2011-01-01

    Purpose Age-related macular degeneration (AMD) has a complex etiology arising from genetic and environmental influences. This past decade have seen several genes associated with the disease. Variants in five genes have been confirmed to play a major role. The objective of this study was to evaluate whether genes influence treatment response to ranibizumab for neovascular AMD. The hypothesis was that an individual’s genetic variation will determine treatment response. Methods The study was a two-site prospective open-label observational study of patients newly diagnosed with exudative (neovascular) AMD receiving intravitreal ranibizumab therapy. Treatment-naïve patients were enrolled at presentation and received monthly “as needed” therapy. Clinical data was collected monthly and DNA extracted. Genotyping was performed using the Illumina (San Diego, California) 660-Quad single-nucleotide polymorphism (SNP) chip. Regression analyses were performed to identify SNPs associated with treatment-response end points. Results Sixty-five patients were enrolled. No serious adverse events were recorded. The primary outcome measure was change in ETDRS visual acuity at 12 months. A SNP in the CFH gene was found to be associated with less improvement in visual acuity while receiving ranibizumab therapy. The C3 gene, among others, was associated with reduced thickening and improved retinal architecture. VEGFA, FLT1, and CFH were associated with requiring fewer ranibizumab injections over the 12-month study. Conclusions This study is one of the first prospective pharmacogenetic study of intravitreal ranibizumab. Although preliminary, the results identify a number of putative genetic variants, which will be further examined by replication and functional studies to elucidate the complete pharmacogenetic architecture of therapy for AMD.

    Age-related oral changes are seen in the oral hard and soft tissues as well as in bone, the temporomandibular joints and the oral mucosa. As older patients retain their natural teeth for longer, the clinical picture consists of normal physiological age changes in combination with pathological and iatrogenic effects. Clinical Relevance: With an ageing population retaining more of its natural teeth for longer, dental professionals should expect to observe oral age changes more frequently.

    2014-09-01

    During the course of normal aging, biological changes occur in the brain that are associated with changes in cognitive ability. This review presents data from neuroimaging studies of primarily "normal" or healthy brain aging. As such, we focus on research in unimpaired or nondemented older adults, but also include findings from lifespan studies that include younger and middle aged individuals as well as from populations with prodromal or clinically symptomatic disease such as cerebrovascular or Alzheimer's disease. This review predominantly addresses structural MRI biomarkers, such as volumetric or thickness measures from anatomical images, and measures of white matter injury and integrity respectively from FLAIR or DTI, and includes complementary data from PET and cognitive or clinical testing as appropriate. The findings reveal highly consistent age-related differences in brain structure, particularly frontal lobe and medial temporal regions that are also accompanied by age-related differences in frontal and medial temporal lobe mediated cognitive abilities. Newer findings also suggest that degeneration of specific white matter tracts such as those passing through the genu and splenium of the corpus callosum may also be related to age-related differences in cognitive performance. Interpretation of these findings, however, must be tempered by the fact that comorbid diseases such as cerebrovascular and Alzheimer's disease also increase in prevalence with advancing age. As such, this review discusses challenges related to interpretation of current theories of cognitive aging in light of the common occurrence of these later-life diseases. Understanding the differences between "Normal" and "Healthy" brain aging and identifying potential modifiable risk factors for brain aging is critical to inform potential treatments to stall or reverse the effects of brain aging and possibly extend cognitive health for our aging society.

    2003-08-01

    The subject of the following article is 'old age' of women and men in prehistoric times, in the ancient Greek and Roman times, in the Middle Ages, in the Age of Enlightenment, in the times of the western industrial civilization and finally in the so-called post-modern civilization (in German terms "Erlebnisgesellschaft") of the present. There is a double focus on the subject. On one hand, the examination deals with the concrete circumstances of living of the elderly people. On the other hand, the examination analyzes the images of old age and the dominant image of the elderly people in the different times. The historical focus shows that old age is no anthropological or biological, unchangeable condition. Old age is a social and cultural construction that is historically formed and can be changed by society. This statement is valid for the number of the elderly in relation to the whole population of a historical society, it is valid for the way of every day life of the elderly and it is also valid to answer the question, who is an 'old' person. 'Old age' and the appearance of 'old age' depends on gender, on sociological items and last but not least on individual conditions during the different historical times. Dominant and strongly changing images of old age can be seen in all periods of human culture, in ancient times, in the Middle Ages and also in modern times. These images (negative or positive) depend strongly on the economic circumstances and conditions of living. Connected with these analyzed images of old age in all former cultures are concrete systems of values that have a leading function for the whole society.

    Full Text Available The paper is focused on changes occurred in military organizations in Information Age. During Industrial Age the military structure of forces evolved according with principles of decomposition, specialization, hierarchy, optimization, deconfliction, centralized planning, and decentralized execution. But now the solutions based upon Industrial Age assumptions and practices will break down and fail in the Information Age. This will happen no matter how well intentioned, hardworking, or dedicated the leadership and the force are. Two key force capabilities needed by Information Age militaries are interoperability and agility. Both interoperability and agility are provided by Network centric warfare theory of war.

    Telomeres are gene sequences present at chromosomal ends and are responsible for maintaining genome integrity. Telomere length is maximum at birth and decreases progressively with advancing age and thus is considered as a biomarker of chronological aging. This age associated decrease in the length of telomere is linked to various ageing associated diseases like diabetes, hypertension, Alzheimer's disease, cancer etc. and their associated complications. Telomere length is a result of combined effect of oxidative stress, inflammation and repeated cell replication on it, and thus forming an association between telomere length and chronological aging and related diseases. Thus, decrease in telomere length was found to be important in determining both, the variations in longevity and age-related diseases in an individual. Ongoing and progressive research in the field of telomere length dynamics has proved that aging and age-related diseases apart from having a synergistic effect on telomere length were also found to effect telomere length independently also. Here a short description about telomere length variations and its association with human aging and age-related diseases is reviewed.

    Full Text Available The body of the discussion is devoted to two books, critical editions of Polish translations of the works of Spanish Baroque period, that are related to theatre. The first title in question is the annotated bi-lingual edition of El principe contante by Calderon de la Barca, the drama piece known in Poland as Książe niezłomny [The Constant Prince] and brilliantly translated by Juliusz Słowacki. The other book is the annotated translation of Arte nuevo de hacer comedias en este tiempo [New art of writing plays] by Lope de Vega. Both publications not only evaluate the complex and fascinating picture of Spanish theatrical culture of the Golden Age to the Polish reader, but also substantially widen our understanding of the dependence between the type of the stage and the vision of the world constructed by a playwright and the theatre. They may also provide substantial support, and important inspiration, to theoreticians of theatre and drama, comparatists, historians of ideas, historians of mentality, etc.

    Steel production accounts for 25% of industrial carbon emissions. Long-term forecasts of steel demand and scrap supply are needed to develop strategies for how the steel industry could respond to industrialization and urbanization in the developing world while simultaneously reducing its environmental impact, and in particular, its carbon footprint. We developed a dynamic stock model to estimate future final demand for steel and the available scrap for 10 world regions. Based on evidence from developed countries, we assumed that per capita in-use stocks will saturate eventually. We determined the response of the entire steel cycle to stock saturation, in particular the future split between primary and secondary steel production. During the 21st century, steel demand may peak in the developed world, China, the Middle East, Latin America, and India. As China completes its industrialization, global primary steel production may peak between 2020 and 2030 and decline thereafter. We developed a capacity model to show how extensive trade of finished steel could prolong the lifetime of the Chinese steelmaking assets. Secondary steel production will more than double by 2050, and it may surpass primary production between 2050 and 2060: the late 21st century can become the steel scrap age.

  11. Longevity pathways and memory ageing

    2014-06-01

    Full Text Available The ageing process has been associated with numerous pathologies at the cellular, tissue, and organ level. Decline or loss of brain functions, including learning and memory, is one of the most devastating and feared aspects of ageing. Learning and memory are fundamental processes by which animals adjust to environmental changes, evaluate various sensory signals based on context and experience, and make decisions to generate adaptive behaviours. Age-related memory impairment is an important phenotype of brain ageing. Understanding the molecular mechanisms underlying age-related memory impairment is crucial for the development of therapeutic strategies that may eventually lead to the development of drugs to combat memory loss. Studies in invertebrate animal models have taught us much about the physiology of ageing and its effects on learning and memory. In this review we survey recent progress relevant to conserved molecular pathways implicated in both ageing and memory formation and consolidation.

    Mammalian aging is complex and incompletely understood. Although significant effort has been spent addressing the genetics or, more recently, the pharmacology of aging, the toxicology of aging has been relatively understudied. Just as an understanding of 'carcinogens' has proven crucial to modern cancer biology, an understanding of environmental toxicants that accelerate aging ('gerontogens') will inform gerontology. In this review, we discuss the evidence for the existence of mammalian gerontogens, as well as describe the biomarkers needed to measure the age-promoting activity of a given toxicant. We focus on the effects of putative gerontogens on the in vivo accumulation of senescent cells, a characteristic feature of aging that has a causal role in some age-associated phenotypes.

    Lassen, Aske Juul

    Since the end of the 1990s, the European Union and the World Health Organization have proposed active ageing as the best possible solution to the problem of ageing populations. This dissertation discusses how active ageing policies are constructed, what effects they have in the world, and how...... they are negotiated with everyday practices of the elderly. I have explored these topics via ethnographic fieldwork at two activity centres in the Copenhagen area, via document studies of policy papers and gerontological literature about the concept of activity, and via participation in a public-private innovation...... partnership (PPIP) that developed technologies catering to the active late life. A thorough analysis of active ageing entails studying what precisely active ageing tries to solve. I approach ageing as a matter of concern, a term proposed by Bruno Latour to describe how myriad practices and disputed facts...

  1. Mars Ice Age, Simulated

    2003-01-01

    December 17, 2003This simulated view shows Mars as it might have appeared during the height of a possible ice age in geologically recent time.Of all Solar System planets, Mars has the climate most like that of Earth. Both are sensitive to small changes in orbit and tilt. During a period about 2.1 million to 400,000 years ago, increased tilt of Mars' rotational axis caused increased solar heating at the poles. A new study using observations from NASA's Mars Global Surveyor and Mars Odyssey orbiters concludes that this polar warming caused mobilization of water vapor and dust into the atmosphere, and buildup of a surface deposit of ice and dust down to about 30 degrees latitude in both hemispheres. That is the equivalent of the southern Unites States or Saudi Arabia on Earth. Mars has been in an interglacial period characterized by less axial tilt for about the last 300,000 years. The ice-rich surface deposit has been degrading in the latitude zone of 30 degrees to 60 degrees as water-ice returns to the poles.In this illustration prepared for the December 18, 2003, cover of the journal Nature, the simulated surface deposit is superposed on a topography map based on altitude measurements by Global Surveyor and images from NASA's Viking orbiters of the 1970s.Mars Global Surveyor and Mars Odyssey are managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, for the NASA Office of Space Science, Washington.

Most authors in the field agree active aging is a multidimensional concept, embracing health, physical and cognitive fitness, positive affect and control, social relationships and engagement. This paper describes Vital Aging, an individual active aging promotion program implemented through three modalities: Life, Multimedia, and e-Learning. The program was developed on the basis of extensive evidence about individual determinants of active aging. The different versions of Vital Aging are described, and four evaluation studies (both formative and summative are reported. Formative evaluation reflected participants’ satisfaction and expected changes; summative evaluations yielded some quite encouraging results using quasi-experimental designs: those who took part in the programs increased their physical exercise, significantly improved their diet, reported better memory, had better emotional balance, and enjoyed more cultural, intellectual, affective, and social activities than they did before the course, thus increasing their social relationships. These results are discussed in the context of the common literature within the field and, also, taking into account the limitations of the evaluations accomplished.

    Due to the insufficient information regarding the aging phenomenon of cables caused by switching impulses,we aged 15 kV XLPE and EPR cable samples by 10000 switching impulses in experiments and tested them.Plus in order to compare the aging phenomenon under multi-stress conditions,additional EPR cable samples were aged by rated AC voltage and current with switching impulses superimposed.We used measurements of partial discharge parameters to monitor the cables' conditions during their aging process,and the AC breakdown voltages measurement to evaluate the cables after aging.Moreover,the Fourier transform infrared (FTIR) spectroscopy measurements revealed the changes of insulation materials after aging.The measurement results confirm that the accelerated aging of cable samples had taken place.The impacts of each individual aging factor are shown through the selected measurements and comparison.The study also helps to assess the reliability of the XLPE and EPR cables under similar condition while serving in power systems.

  5. Evolution of ageing since Darwin

    2008-12-01

    In the late 19th century, the evolutionary approach to the problem of ageing was initiated by August Weismann, who argued that natural selection was more important for ageing than any physiological mechanism. In the mid-twentieth century, J. B. S. Haldane, P. B. Medawar and G. C. Williams informally argued that the force of natural selection falls with adult age. In 1966, W. D. Hamilton published formal equations that showed mathematically that two ‘forces of natural selection’ do indeed decline with age, though his analysis was not genetically explicit. Brian Charlesworth then developed the required mathematical population genetics for the evolution of ageing in the 1970’s. In the 1980’s, experiments using Drosophila showed that the rate of ageing evolves as predicted by Hamilton’s ‘forces of natural selection’. The discovery of the cessation of ageing late in life in the 1990’s was followed by its explanation in terms of evolutionary theory based on Hamilton’s forces. Recently, it has been shown that the cessation of ageing can also be manipulated experimentally using Hamilton’s ‘forces of natural selection’. Despite the success of evolutionary research on ageing, mainstream gerontological research has largely ignored both this work and the opportunity that it provides for effective intervention in ageing.

  6. Aging and functional brain networks

    2011-07-11

    Aging is associated with changes in human brain anatomy and function and cognitive decline. Recent studies suggest the aging decline of major functional connectivity hubs in the 'default-mode' network (DMN). Aging effects on other networks, however, are largely unknown. We hypothesized that aging would be associated with a decline of short- and long-range functional connectivity density (FCD) hubs in the DMN. To test this hypothesis, we evaluated resting-state data sets corresponding to 913 healthy subjects from a public magnetic resonance imaging database using functional connectivity density mapping (FCDM), a voxelwise and data-driven approach, together with parallel computing. Aging was associated with pronounced long-range FCD decreases in DMN and dorsal attention network (DAN) and with increases in somatosensory and subcortical networks. Aging effects in these networks were stronger for long-range than for short-range FCD and were also detected at the level of the main functional hubs. Females had higher short- and long-range FCD in DMN and lower FCD in the somatosensory network than males, but the gender by age interaction effects were not significant for any of the networks or hubs. These findings suggest that long-range connections may be more vulnerable to aging effects than short-range connections and that, in addition to the DMN, the DAN is also sensitive to aging effects, which could underlie the deterioration of attention processes that occurs with aging.

    Age-related cognitive decline is a major concern in society. Here, I discuss recent evidence that shows an age-related modulation of gene transcription by epigenetic modifications. Epigenetic modifications, such as histone acetylation, is unbalanced in aging, with an increase in histone deacetylation, that limits the expression of plasticity-related genes. By modifying the balance towards histone acetylation, histone deacetylase inhibitors present a new pharmacological approach to ameliorate age-related cognitive deficits.

    1991-10-01

    This study investigated the influence of aging on memory for home drams and the extent to which cognitive variables such as visual memory, visuospatial IQ, and verbal IQ could account for possible differences herein. Subjects were 80 men and women of ages 45 to 75 years. Memory for dreams was measured by narrative length and frequency of recall. With respect to both measures no significant age differences were noted. Over-all differences in dream recall seemed best explained by visual memory scores. Partial correlational analyses, however, indicated that the small age differences memory or on any of the other cognitive variables. Dream contents were scored for aggression, friendliness, emotion, activities, and the number of characters and objects. The incidence of emotions among women appeared to be lower beyond the age of 60. Comparisons with previous data for young adults indicated that large reductions in aggression, friendliness, and emotion occur before the age of 45.

    This report retrospectively analyzed the outcome of 91 patients aged 60 years or older with refractory/relapsed (R/R) classical Hodgkin's lymphoma (cHL) who underwent autologous stem cell transplantation (ASCT) between 1992 and 2013 and were reported to the French Society of Bone Marrow Transplantation and Cell Therapies registry. The median age at transplant was 63 years. The majority of patients exhibited disease chemosensitivity to salvage treatment (57 complete responses, 30 partial responses, 1 progressive disease and 3 unknown). The most frequent conditioning regimen consisted of BCNU, cytarabine, etoposide, melphalan (BEAM) chemotherapy (93%). With a median follow-up of 54 months, 5-year estimates of overall survival (OS) and progression free survival (PFS) for the entire group were 67 and 54%, respectively. Despite the missing data, in univariate analysis, the number of salvage chemotherapy lines (1-2 versus ⩾3) significantly influenced the OS, unlike the other prognostic factors (stage III-IV at relapse, disease status before ASCT and negative positron emission tomography (PET) scan) encountered in younger patients. In spite of its limitations, this retrospective study with a long-term follow-up suggests that ASCT is a valid treatment option for chemosensitive R/R cHL in selected elderly patients, with an acceptable rate of toxicity.

  12. Leisure in old age – disciplinary practices surrounding the discourse of active ageing

    Directory of Open Access Journals (Sweden)

    Jaroslava Hasmanová Marhánkova

    2011-10-01

    Full Text Available In the 1990s, the World Health Organization adopted the term ‘‘active ageing’’, which currently represents a key vision of old age in Western societies facing the situation of demographic ageing. The meaning of the idea of active ageing is based on the concept of individuals actively and systematically influencing the conditions of their ageing through selfresponsibility and self-care. The aim of this article is to map how the idea of active ageing is constructed and the implications it presents with regard to the way in which seniors relate to their experience of old age. It concentrates on a pecific segment of senior-oriented social services (centres for seniors that offer leisure time activities and educational courses that represent an institutional context for the manifestation of the discourse of active ageing. A three-year ethnographic study was conducted in two such centres in the Czech Republic. The article focuses on various strategies for the disciplining of the ageing body. It points out that these disciplinary practices are an integral part of the daily running of the centres and that the seniors who intensively engage in them have internalised the idea of an active lifestyle as the most desirable lifestyle in old age. Active ageing was constructed by them as a project that must be worked on. Through the ‘‘technologies of self’’ embedded in the imperative of the necessity to move or do something, they participate in the production of the discourse of active ageing as a form of discipline of the body. At the same time, the article outlines how the idea of active ageing as the ‘‘correct’’ form of ageing influences the self-conception of these seniors and their attitudes towards ageing and their peers.

    2013-09-01

    Drug addiction is often underestimated among the aged. Opiate drugs (mostly pain killers) are the most frequently implicated in drug addiction after benzodiazepines (BZD) in the aged. The subjects aged of 65 years or more are the most represented among the BZD users in France. Frequency of BZD use varies according to various studies from 39 to 55% in this age group. Leading a lonely life is associated with the use of psychotropic drugs among retired people (OR=1.7). Vulnerability at this age must take into account not only polypathology, but also the faster aging of a minority of the population under opiate drugs substitution treatment (OST), more subjects to drugs interaction. Drug addiction among elderly often reflects the drift of "lawful" doctor's instructions that leads to an increase in drugs use. The difficulty has to do with a lack of specificity of diagnosis of addiction at this age, but perhaps also with physicans'instructions in the aged. Some authors suggest that continued and prolonged use should be considered the main criterion for BZD addiction at this age, with or without increase in doses and failed attempt at cessation. Besides, the prescription of BZD increases after retirement and loneliness.

    We present a model for biological aging that considers the number of individuals whose (inherited) genetic charge determines the maximum age for death: each individual may die before that age due to some external factor, but never after that limit. The genetic charge of the offspring is inherited from the parent with some mutations, described by a transition matrix. The model can describe different strategies of reproduction and it is exactly soluble. We applied our method to the bit-string model for aging and the results are in perfect agreement with numerical simulations.

  4. Age and the endocrine system.

    The pattern of age-induced changes in each endocrine system is unique. Both hormone levels and target organ responsivity are altered in the aging endocrine-cardiovascular system. Serum levels of vasopressor hormones both increase (norepinephrine) and decrease (renin, aldosterone). Target organ responses to beta-adrenergic stimulation in the heart and probably also in vascular smooth muscle decrease due to postreceptor changes. These effects contribute to the clinical problems of hypertension and orthostatic hypotension which characterize the elderly. Aging produces mild carbohydrate intolerance and a minimal increase in fasting serum glucose in healthy, nonobese individuals, primarily due to decreasing postreceptor responsiveness to insulin. Aging decreases the metabolism of thyroxine, including its conversion to triiodothyronine, but clinically significant alterations of thyroid hormone levels do not occur. Changes in the end-organ response to thyroid hormones, however, significantly alter the clinical presentation of thyroid diseases. Aging shifts the serum vasopressin-serum osmolality relationship toward higher serum vasopressin levels probably due to altered baroreceptor input, probably contributing to the tendency toward hyponatremia in the elderly. Aging slows the metabolism of cortisol, but glucocorticoid levels in the human are essentially unaltered by age. However, recent data indicate that delta-5 adrenal steroids decrease markedly in both men and women. Nodules in the anterior pituitary, the thyroid, and the adrenal increase in frequency with aging. Finally, the reproductive system is primarily altered by endocrine cell death, by unknown mechanisms, resulting in decreased estrogen and testosterone levels in women and men. This most obvious age-related endocrine change turns out to be incompletely understood and is not representative of most age-related endocrine changes. Despite characterization of these many age-related alterations in endocrine systems

    2012-01-01

    Data linking specific ages or age ranges with disease are abundant in biomedical literature. However, these data are organized such that searching for age-phenotype relationships is difficult. Recently, we described the Age-Phenome Knowledge-base (APK), a computational platform for storage and retrieval of information concerning age-related phenotypic patterns. Here, we report that data derived from over 1.5 million human-related PubMed abstracts have been added to APK. Using a text-mining pipeline, 35,683 entries which describe relationships between age and phenotype (such as disease) have been introduced into the database. Comparing the results to those obtained by a human reader reveals that the overall accuracy of these entries is estimated to exceed 80%. The usefulness of these data for obtaining new insight regarding age-disease relationships is demonstrated using clustering analysis, which is shown to capture obvious, as well as potentially interesting relationships between diseases. In addition, a new tool for browsing and searching the APK database is presented. We thus present a unique resource and a new framework for studying age-disease relationships and other phenotypic processes.

  19. Calcium Homeostasis in ageing neurons

    Directory of Open Access Journals (Sweden)

    Vassiliki eNikoletopoulou

    2012-10-01

    Full Text Available The nervous system becomes increasingly vulnerable to insults and prone to dysfunction during ageing. Age-related decline of neuronal function is manifested by the late onset of many neurodegenerative disorders, as well as by reduced signalling and processing capacity of individual neuron populations. Recent findings indicate that impairment of Ca2+ homeostasis underlies the increased susceptibility of neurons to damage, associated with the ageing process. However, the impact of ageing on Ca2+ homeostasis in neurons remains largely unknown. Here, we survey the molecular mechanisms that mediate neuronal Ca2+ homeostasis and discuss the impact of ageing on their efficacy. To address the question of how ageing impinges on Ca2+ homeostasis, we consider potential nodes through which mechanisms regulating Ca2+ levels interface with molecular pathways known to influence the process of ageing and senescent decline. Delineation of this crosstalk would facilitate the development of interventions aiming to fortify neurons against age-associated functional deterioration and death by augmenting Ca2+ homeostasis.

    As average life expectancy increases there is a greater focus on health-span and, in particular, how to treat or prevent chronic age-associated diseases. Therapies which were able to control 'biological age' with the aim of postponing chronic and costly diseases of old age require an entirely new approach to drug development. Molecular technologies and machine-learning methods have already yielded diagnostics that help guide cancer treatment and cardiovascular procedures. Discovery of valid and clinically informative diagnostics of human biological age (combined with disease-specific biomarkers) has the potential to alter current drug-discovery strategies, aid clinical trial recruitment and maximize healthy ageing. I will review some basic principles that govern the development of 'ageing' diagnostics, how such assays could be used during the drug-discovery or development process. Important logistical and statistical considerations are illustrated by reviewing recent biomarker activity in the field of Alzheimer's disease, as dementia represents the most pressing of priorities for the pharmaceutical industry, as well as the chronic disease in humans most associated with age.

    The development of presbycusis, or age-related hearing loss, is determined by a combination of genetic and environmental factors. The auditory periphery exhibits a progressive bilateral, symmetrical reduction of auditory sensitivity to sound from high to low frequencies. The central auditory nervous system shows symptoms of decline in age-related cognitive abilities, including difficulties in speech discrimination and reduced central auditory processing, ultimately resulting in auditory perceptual abnormalities. The pathophysiological mechanisms of presbycusis include excitotoxicity, oxidative stress, inflammation, aging and oxidative stress-induced DNA damage that results in apoptosis in the auditory pathway. However, the originating signals that trigger these mechanisms remain unclear. For instance, it is still unknown whether insulin is involved in auditory aging. Auditory aging has preclinical lesions, which manifest as asymptomatic loss of periphery auditory nerves and changes in the plasticity of the central auditory nervous system. Currently, the diagnosis of preclinical, reversible lesions depends on the detection of auditory impairment by functional imaging, and the identification of physiological and molecular biological markers. However, despite recent improvements in the application of these markers, they remain under-utilized in clinical practice. The application of antisenescent approaches to the prevention of auditory aging has produced inconsistent results. Future research will focus on the identification of markers for the diagnosis of preclinical auditory aging and the development of effective interventions.

    Although species longevity is subject to a diverse range of evolutionary forces, the mortality curves of a wide variety of organisms are rather similar. Here we argue that qualitative and quantitative features of aging can be reproduced by a simple model based on the interdependence of fault-prone agents on one other. In addition to fitting our theory to the empiric mortality curves of six very different organisms, we establish the dependence of lifetime and aging rate on initial conditions, damage and repair rate, and system size. We compare the size distributions of disease and death and see that they have qualitatively different properties. We show that aging patterns are independent of the details of interdependence network structure, which suggests that aging is a many-body effect, and that the qualitative and quantitative features of aging are not sensitively dependent on the details of dependency structure or its formation.

    2015-12-04

    Research into stem cells and aging aims to understand how stem cells maintain tissue health, what mechanisms ultimately lead to decline in stem cell function with age, and how the regenerative capacity of somatic stem cells can be enhanced to promote healthy aging. Here, we explore the effects of aging on stem cells in different tissues. Recent research has focused on the ways that genetic mutations, epigenetic changes, and the extrinsic environmental milieu influence stem cell functionality over time. We describe each of these three factors, the ways in which they interact, and how these interactions decrease stem cell health over time. We are optimistic that a better understanding of these changes will uncover potential strategies to enhance stem cell function and increase tissue resiliency into old age.

    With advancing age, the ability of humans to detect and discriminate odors declines. In light of the rapid progress in analyzing molecular and structural correlates of developing and adult olfactory systems, the paucity of information available on the aged olfactory system is startling. A rich literature documents the decline of olfactory acuity in aged humans, but the underlying cellular and molecular mechanisms are largely unknown. Using animal models, preliminary work is beginning to uncover differences between young and aged rodents that may help address the deficits seen in humans, but many questions remain unanswered. Recent studies of odorant receptor (OR) expression, synaptic organization, adult neurogenesis, and the contribution of cortical representation during aging suggest possible underlying mechanisms and new research directions.

  7. Nutraceuticals, aging, and cognitive dysfunction.

    Head, Elizabeth; Zicker, Steven C

    2004-01-01

    Decline in cognitive function that accompanies aging in dogs might have a biological basis, and many of the disorders associated with aging in canines might be preventable through dietary modifications that incorporate specific nutraceuticals. Based on previous research and the results of laboratory and clinical studies, antioxidants might be one class of nutraceutical that benefits aged dogs. Brains of aged dogs accumulate oxidative damage to proteins and lipids, which can lead to dysfunction of neuronal cells. The production of free radicals and lack of increase in compensatory antioxidant enzymes might lead to detrimental modifications to important macromolecules within neurons. Reducing oxidative damage through food ingredients rich in a broad spectrum of antioxidants significantly improves, or slows the decline of, learning and memory in aged dogs; however, determining which compounds, combinations, dosage ranges, when to initiate intervention, and long-term effects constitute critical gaps in knowledge about this subject.

  8. Space Age Archaeology

    1988-01-01

    In 1985, the Egyptian Antiques Organization (EAO) asked Dr. Farouk El-Baz whether it would be possible to examine and sample the second chamber of the subterranean chamber carved in the bedrock near the Great Pyramid of Khufu in Giza, Egypt, without admitting people, air or contaminants. He felt it could by applying space technology to the task. The initial contact led to a two year project which he organized and headed a team, co-sponsored by EAO and the National Geographic Society (NGS), to apply space technology in an effort to examine and photograph the Giza Chamber. The NGS photographic division modified and tested a remotely controlled video system and a 35-millimeter camera, and developed a lighting system that would not elevate the chamber temperature. Still needed was a drill to cut through the limestone cap without using lubricants or cooling fluids that might contaminate the chamber, and an airlock that would admit the drill shaft and photo equipment but not the air. Bob Moores from Black & Decker Corporation tailored a new drill to the Giza exploration. The drill bit broke through into the chamber at a depth of 63 inches, a stainless steel tube was lowered through the airlock to take samples of the chamber air at several levels. The video camera sent images from the chamber revealing that there was a disassembled royal boat that had been there.

  9. The quality control theory of aging.

    Science.gov (United States)

    Ladiges, Warren

    2014-01-01

    The quality control (QC) theory of aging is based on the concept that aging is the result of a reduction in QC of cellular systems designed to maintain lifelong homeostasis. Four QC systems associated with aging are 1) inadequate protein processing in a distressed endoplasmic reticulum (ER); 2) histone deacetylase (HDAC) processing of genomic histones and gene silencing; 3) suppressed AMPK nutrient sensing with inefficient energy utilization and excessive fat accumulation; and 4) beta-adrenergic receptor (BAR) signaling and environmental and emotional stress. Reprogramming these systems to maintain efficiency and prevent aging would be a rational strategy for increased lifespan and improved health. The QC theory can be tested with a pharmacological approach using three well-known and safe, FDA-approved drugs: 1) phenyl butyric acid, a chemical chaperone that enhances ER function and is also an HDAC inhibitor, 2) metformin, which activates AMPK and is used to treat type 2 diabetes, and 3) propranolol, a beta blocker which inhibits BAR signaling and is used to treat hypertension and anxiety. A critical aspect of the QC theory, then, is that aging is associated with multiple cellular systems that can be targeted with drug combinations more effectively than with single drugs. But more importantly, these drug combinations will effectively prevent, delay, or reverse chronic diseases of aging that impose such a tremendous health burden on our society.

    2013-11-01

    Aging is a complex phenomenon involving multiple physiological functions. Among these, very important are the modifications induced in the immune system; these modifications may be related to cancer development, a disease of older people. We herein describe the age-dependent alterations observed in the various arms of the immune system. Both innate and adaptive immunity are compromised during aging, a condition where an inflammatory status contributes to promote immune suppression and tumour growth. Collectively, aging of the immune system may produce detrimental consequences on the response against tumours in old patients. In fact, preclinical studies and clinical observations in humans have demonstrated age-associated alterations in antitumor immunity. Immunological recovery of old patients after conventional chemotherapy (CT) has not been fully investigated, while several studies conducted in patients undergoing blood stem cell transplantation have demonstrated that a delayed immune reconstitution associated with older age results in increased susceptibility to opportunistic infections and risk of tumour relapse. Cellular immunotherapy and vaccination are becoming viable options for improving survival and quality of life of cancer patients targeting both the host defences and the tumour. The clinical experience in elderly patients is still in its infancy, but available data indicate that these approaches are feasible and promising. A key problem in the studies on aging, immunity and cancer is that it is difficult to distinguish changes related to age from those related to cancer-dependent immunosuppression, but independent from the age of the subject. Longitudinal studies on aged healthy and cancer persons and the use of new immunological techniques may be required to clarify these issues.

  12. Aging and skilled problem solving.

    Science.gov (United States)

    Charness, N

    1981-03-01

    Information-processing models of problem solving too often are based on restrictive age ranges. On the other hand, gerontologists have investigated few problem-solving tasks and have rarely generated explicit models. As this article demonstrates, both fields can benefit by closer collaboration. One major issue in gerontology is whether aging is associated with irreversible decrement or developmental plasticity. If both processes occur, then an appropriate strategy for investigating aging is to equate age groups for molar problem-solving performance and search for differences in the underlying components. This strategy was adopted to examine the relation of age and skill to problem solving in chess. Chess players were selected to vary widely in age and skill such that these variables were uncorrelated. Problem-solving and memory tasks were administered. Skill level was the only significant predictor for accuracy in both a choose-a-move task and a speeded end-game evaluation task. Age (negatively) and skill (positively) jointly determined performance in an unexpected recall task. Efficient chunking in recall was positively related to skill, though negatively related to age. Recognition confidence, though not accuracy, was negatively related to age. Thus despite age-related declines in encoding and retrieval of information, older players match the problem-solving performance of equivalently skilled younger players. Apparently, they can search the problem space more efficiently, as evidenced by taking less time to select an equally good move. Models of chess skill that stress that role of encoding efficiency, as indexed by chunking in recall, need to be modified to account for performance over the life span.

    Full Text Available This study is aimed to understand transgender aging context in Brazil. Normal and abnormal were especially created by biological sciences. For being considered deviants, transgender people are not seen as human beings. They end up living in violent environments. Their life expectancy is low. Many of them do not believe to reach old age. They face a lot of prejudice and death threat. Those who get to what we call old age are considered survivals. This investigation was able to show satisfactorily their demands and needs. To be considered visible, they have to count on public policies to give them existence since their childhood. That way, we believe they will reach what we call old age with respect and dignity, already assured by the Universal Human Rights.

    Youth, which is forgiven everything, forgives itself nothing: age, which forgives itself everything, is forgiven nothing. George Bernard Shaw The proportion of older people in the general population is steadily increasing worldwide, with the most rapid growth in low-and middle-income countries [1]. This demographic change is to be celebrated, because it is the consequence of socioeconomic development and better life expectancy. However, population aging also has important implications for society - in diverse areas including health systems, labor markets, public policy, social programs, and family dynamics [2]. A successful response to the aging population will require capitalizing on the opportunities that this transition offers, as well as effectively addressing its challenges. Chronic kidney disease (CKD) is an important public health problem that is characterized by poor health outcomes and very high health care costs. CKD is a major risk multiplier in patients with diabetes, hypertension, heart disease and stroke - all of which are key causes of death and disability in older people [3]. Since the prevalence of CKD is higher in older people, the health impact of population aging will depend in part on how the kidney community responds. March 13, 2014 will mark the celebration of the 9th World Kidney Day (WKD), an annual event jointly sponsored by the International Society of Nephrology and the International Federation of Kidney Foundations. Since its inception in 2006, WKD has become the most successful effort to raise awareness among policymakers and the general public about the importance of kidney disease. The topic for WKD 2014 is "CKD in older people". This article reviews the key links between kidney function, age, health and illness - and discusses the implications of the aging population for the care of people with CKD.

    2012-01-01

    Full Text Available Age-related skin changes can be induced by chronological ageing, manifested in subcutaneous fat reduction, and photo-ageing eliciting increased elastotic substance in the upper dermis, destruction of its fibrilar structure, augmented intercellular substance and moderate inflammatory infiltrate. Forty-five biopsy skin samples of the sun-exposed and sun-protected skin were analyzed. The patients were both males and females, aged from 17 to 81 years. The thickness of the epidermal layers and the number of cellular living layers is greater in younger skin. The amount of keratohyaline granules is enlarged in older skin. Dermoepidermal junction is flattened and the presence of elastotic material in the dermis is pronounced with age. The amount of inflammatory infiltrate is increased, the fibrous trabeculae are thickened in older skin and the atrophy of the hypodermis is observed. Chronological ageing alters the fibroblasts metabolism by reducing their life span, capacity to divide and produce collagen. During ageing, the enlargement of collagen fibrils diminishes the skin elasticity.

  19. The cell biology of aging

    DiLoreto, Race; Murphy, Coleen T.

    2015-01-01

    One of the original hypotheses of organismal longevity posits that aging is the natural result of entropy on the cells, tissues, and organs of the animal—a slow, inexorable slide into nonfunctionality caused by stochastic degradation of its parts. We now have evidence that aging is instead at least in part genetically regulated. Many mutations have been discovered to extend lifespan in organisms of all complexities, from yeast to mammals. The study of metazoan model organisms, such as Caenorhabditis elegans, has been instrumental in understanding the role of genetics in the cell biology of aging. Longevity mutants across the spectrum of model organisms demonstrate that rates of aging are regulated through genetic control of cellular processes. The regulation and subsequent breakdown of cellular processes represent a programmatic decision by the cell to either continue or abandon maintenance procedures with age. Our understanding of cell biological processes involved in regulating aging have been particularly informed by longevity mutants and treatments, such as reduced insulin/IGF-1 signaling and dietary restriction, which are critical in determining the distinction between causes of and responses to aging and have revealed a set of downstream targets that participate in a range of cell biological activities. Here we briefly review some of these important cellular processes. PMID:26668170

    One of the challenges in automatic face recognition is to achieve temporal invariance. In other words, the goal is to come up with a representation and matching scheme that is robust to changes due to facial aging. Facial aging is a complex process that affects both the 3D shape of the face and its texture (e.g., wrinkles). These shape and texture changes degrade the performance of automatic face recognition systems. However, facial aging has not received substantial attention compared to other facial variations due to pose, lighting, and expression. We propose a 3D aging modeling technique and show how it can be used to compensate for the age variations to improve the face recognition performance. The aging modeling technique adapts view-invariant 3D face models to the given 2D face aging database. The proposed approach is evaluated on three different databases (i.g., FG-NET, MORPH, and BROWNS) using FaceVACS, a state-of-the-art commercial face recognition engine.

    Full Text Available Aging is associated with physiological declines, notably a decrease in bone mineral density (BMD and lean body mass, with a concurrent increase in body fat and central adiposity. Interest in women and aging is of particular interest partly as a result of gender specific responses to aging, particularly as a result of menopause. It is possible that the onset of menopause may augment the physiological decline associated with aging and inactivity. More so, a higher incidence of metabolic syndrome (an accumulation of cardiovascular disease risk factors including obesity, low-density lipoprotein cholesterol, high blood pressure, and high fasting glucose has been shown in middle-aged women during the postmenopausal period. This is due in part to the drastic changes in body composition, as previously discussed, but also a change in physical activity (PA levels. Sarcopenia is an age related decrease in the cross-sectional area of skeletal muscle fibers that consequently leads to a decline in physical function, gait speed, balance, coordination, decreased BMD, and quality of life. PA plays an essential role in combating physiological decline associated with aging. Maintenance of adequate levels of PA can result in increased longevity and a reduced risk for metabolic disease along with other chronic diseases. The aim of this paper is to review relevant literature, examine current PA guidelines, and provide recommendations specific to women based on current research.

    Full Text Available Abstract Aging is associated with a decline in immune function (immunosenescence, a situation known to correlate with increased incidence of cancer, infectious and degenerative diseases. Innate, cellular and humoral immunity all exhibit increased deterioration with age. A decrease in functional competence of individual natural killer (NK cells is found with advancing age. Macrophages and granulocytes show functional decline in aging as evidenced by their diminished phagocytic activity and impairment of superoxide generation. There is also marked shift in cytokine profile as age advances, e.g., CD3+ and CD4+ cells decline in number whereas CD8+ cells increase in elderly individuals. A decline in organ specific antibodies occurs causing reduced humoral responsiveness. Circulating melatonin decreases with age and in recent years much interest has been focused on its immunomodulatory effect. Melatonin stimulates the production of progenitor cells for granulocytes-macrophages. It also stimulates the production of NK cells and CD4+ cells and inhibits CD8+ cells. The production and release of various cytokines from NK cells and T-helper lymphocytes also are enhanced by melatonin. Melatonin presumably regulates immune function by acting on the immune-opioid network, by affecting G protein-cAMP signal pathway and by regulating intracellular glutathione levels. Melatonin has the potential therapeutic value to enhance immune function in aged individuals and in patients in an immunocompromised state.

    Full Text Available Abstract Normal aging can be characterized by a gradual decline in some cognitive functions, such as memory. Memory complaints are common among older adults, and may indicate depression, anxiety, or cognitive decline. Objectives: To investigate the association between memory complaints and age in cognitively unimpaired older adults, and the relationship between memory complaints and memory performance. Methods: Cognitive screening tests as well as memory complaint questionnaires validated for the Brazilian population were used: the Mini-Mental State Examination (MMSE, Geriatric Depression Scale (GDS, Memory Complaint Questionnaire (MAC-Q, Memory test of 18 pictures, Forward and Backward Digit Span (WAIS-III. Fifty seven regular members of the SESC social club participated (50 women, having a mean age of 71.4 years, and 4 to 8 years of education - 34 from 4 to 7 years and 23 with 8 years of education. Results: Results revealed no significant association between cognitive complaints and age or cognitive performance. Older participants in this sample did not show worse performance or a higher level of complaints. There was no significant association between age and GDS scores. Conclusions: The studied sample constitutes a particular group of older adults whose participation in activities may be protecting them from cognitive decline, thus highlighting the impact of lifestyle on cognitive performance during the aging process.

    As biometrics-based identification and identity authentication become increasingly widespread in their deployment, it becomes correspondingly important to consider more carefully issues relating to reliability, usability and inclusion. One factor which is particularly important in this context is that of the relationship between the nature of the measurements extracted from a particular biometric modality and the age of the sample donor, and the effect which age has on physiological and behavioural characteristics invoked in a biometric transaction.

    2016-01-01

    Aging research is undergoing a paradigm shift, which has led to new and innovative methods of exploring this complex phenomenon. The systems biology approach endeavors to understand biological systems in a holistic manner, by taking account of intrinsic interactions, while also attempting to account for the impact of external inputs, such as diet. A key technique employed in systems biology is computational modeling, which involves mathematically describing and simulating the dynamics of biological systems. Although a large number of computational models have been developed in recent years, these models have focused on various discrete components of the aging process, and to date no model has succeeded in completely representing the full scope of aging. Combining existing models or developing new models may help to address this need and in so doing could help achieve an improved understanding of the intrinsic mechanisms which underpin aging.

    2002-02-28

    Impairment in cholinergic systems is a highly consistent finding in human dementia. Among cholinergic markers, marked decreases in nicotine binding have been most consistently observed in the telencephalic regions of demented patients and are thought to contribute to the cognitive deficits associated with ageing and age-related neurodegenerative diseases. New evidence that the cholinergic system has a specific pathogenic role in the neurodegenerative alterations of aged and, especially, demented patients is fast accumulating. Both in vivo and in culture, nicotine protects striatal, hippocampal and cortical neurons against the neurotoxicity induced by excitotoxic amino acids as well as the toxicity caused by beta-amyloid, the major component of senile plaques. Further support for the implication of nicotinic receptors in brain ageing is come from recent studies on transgenic animals lacking nicotinic receptor subtypes, which shed light on the mechanisms of nicotine neuroprotection and neurotoxicity.

  11. Subjective wellbeing, health, and ageing.

    Subjective wellbeing and health are closely linked to age. Three aspects of subjective wellbeing can be distinguished-evaluative wellbeing (or life satisfaction), hedonic wellbeing (feelings of happiness, sadness, anger, stress, and pain), and eudemonic wellbeing (sense of purpose and meaning in life). We review recent advances in the specialty of psychological wellbeing, and present new analyses about the pattern of wellbeing across ages and the association between wellbeing and survival at older ages. The Gallup World Poll, a continuing survey in more than 160 countries, shows a U-shaped relation between evaluative wellbeing and age in high-income, English speaking countries, with the lowest levels of wellbeing in ages 45-54 years. But this pattern is not universal. For example, respondents from the former Soviet Union and eastern Europe show a large progressive reduction in wellbeing with age, respondents from Latin America also shows decreased wellbeing with age, whereas wellbeing in sub-Saharan Africa shows little change with age. The relation between physical health and subjective wellbeing is bidirectional. Older people with illnesses such as coronary heart disease, arthritis, and chronic lung disease show both increased levels of depressed mood and impaired hedonic and eudemonic wellbeing. Wellbeing might also have a protective role in health maintenance. In an analysis of the English Longitudinal Study of Ageing, we identify that eudemonic wellbeing is associated with increased survival; 29·3% of people in the lowest wellbeing quartile died during the average follow-up period of 8·5 years compared with 9·3% of those in the highest quartile. Associations were independent of age, sex, demographic factors, and baseline mental and physical health. We conclude that the wellbeing of elderly people is an important objective for both economic and health policy. Present psychological and economic theories do not adequately account for the variations in patterns

    Honeybee colonies are highly integrated functional units characterized by a pronounced division of labor. Division of labor among workers is mainly age-based, with younger individuals focusing on in-hive tasks and older workers performing the more hazardous foraging activities. Thus, experimental disruption of the age composition of the worker hive population is expected to have profound consequences for colony function. Adaptive demography theory predicts that the natural hive age composition represents a colony-level adaptation and thus results in optimal hive performance. Alternatively, the hive age composition may be an epiphenomenon, resulting from individual life history optimization. We addressed these predictions by comparing individual worker longevity and brood production in hives that were composed of a single age cohort, two distinct age cohorts, and hives that had a continuous, natural age distribution. Four experimental replicates showed that colonies with a natural age composition did not consistently have a higher life expectancy and/or brood production than the single cohort or double cohort hives. Instead, a complex interplay of age structure, environmental conditions, colony size, brood production, and individual mortality emerged. A general trade-off between worker life expectancy and colony productivity was apparent, and the transition from in-hive tasks to foraging was the most significant predictor of worker lifespan irrespective of the colony age structure. We conclude that the natural age structure of honeybee hives is not a colony-level adaptation. Furthermore, our results show that honeybees exhibit pronounced demographic plasticity in addition to behavioral plasticity to react to demographic disturbances of their societies.

    The ASAS (Assessment in SpondyloArtrhritis international Society) classification criteria for axial and peripheral spondyloarthritis permit to classify patients with age at disease onset less than 45 years. Nevertheless, these two forms of spondyloarthritis may begin after the age of 45. With the longer duration of the life expectancy, patients with this late-onset form of spondyloarthritis may be more frequently recognized in the near future. A small percentage (ranging from 3.5 to 6 %) of patients with axial SpA, as defined by the modified New York criteria, have onset of their disease after 45 years of age. Relatively more frequent is the late onset form of peripheral spondyloarthritis with the characteristics of undifferentiated spondyloarthritis. Its clinical spectrum is as broad as it is in children and very young adults. Psoriatic arthritis frequently begins over the age of 45 and occasionally after the age of 60. Some old studies had suggested than elderly-onset psoriatic arthritis is more severe than younger-onset disease, but a recent study found no such difference, and further studies are needed.

    Full Text Available Prostate cancer (PCa is one of the most commonly diagnosed cancers in men worldwide and its incidence increases with age, mainly affecting elderly men aged 60 and above. Factors known to be associated with the development and progression of PCa are age, family history, and race/ethnicity, with age being the most important factor. The reasons for the increased incidence and mortality due to prostate cancer in elderly men are not entirely clear. Continued exposure to environmental and dietary factors may lead to accumulation of genetic and epigenetic changes over the life-span, leading to altered expression and/or activity of tumor promoter and tumor suppressor genes. Changing levels of endogenous hormones (like androgens and metabolism in elderly men may also play a role in the development of prostate cancers which may be further influenced by testosterone replacement therapy. For many decades now preventative strategies and treatments such as radiation therapy or hormone therapy, and others have been administered to manage PCa; however current studies and evidence suggest that PCa is undertreated in elderly men, despite evidence of efficacy of these treatments, which leads to higher prevalence of mortality in this age group. Studies involving basic research, preventative and management strategies are still underway to understand the mechanisms of PCa development in elderly men and treatment of this disease in ageing male population.

    Chromospheric activity has been calibrated and widely used as age indicator. However, it has been suggested that the viability of such an age indicator is, in the best case, limited to stars younger than about 1.5 Gyr. I aim to define the age range for which chromospheric activity is a robust astrophysical clock. I collected literature measurements of the S-index in field stars, which is a measure of the strength of the H and K lines of the Ca II and a proxy for chromospheric activity, and exploited the homogeneous database of temperature and age determinations for field stars provided by the Geneva-Copenhagen survey of the Solar neighbourhood. Field data, inclusive data previously used to calibrate chromospheric ages, confirm the result found using open cluster data, i.e. there is no decay of chromospheric activity after about 2 Gyr. The only existing indication supporting the viability of chromospheric ages larger than 2 Gyr, is the similarity of chromospheric activity levels in the components of 35 dwarf b...

Oxidation and inflammation are implicated in the etiology of these diseases. There is evidence that dietary antioxidants and anti-inflammatories may provide benefit in decreasing the risk of age-related eye disease. Nutrients of interest are vitamins C and E, β-carotene, zinc, lutein, zeaxanthin, and the omega-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid. While a recent survey finds that among the baby boomers (45–65 years old, vision is the most important of the five senses, well over half of those surveyed were not aware of the important nutrients that play a key role in eye health. This is evident from a national survey that finds that intake of these key nutrients from dietary sources is below the recommendations or guidelines. Therefore, it is important to educate this population and to create an awareness of the nutrients and foods of particular interest in the prevention of age-related eye disease.

    Healthy brain aging is characterized by neuronal loss and decline of cognitive function. Neuronal loss is closely associated with microglial activation and postmortem studies have indeed suggested that activated microglia may be present in the aging brain. Microglial activation can be quantified in vivo using (R)-[(11)C]PK11195 and positron emission tomography. The purpose of this study was to measure specific binding of (R)-[(11)C]PK11195 in healthy subjects over a wide age range. Thirty-five healthy subjects (age range 19-79 years) were included. In all subjects 60-minute dynamic (R)-[(11)C]PK11195 scans were acquired. Specific binding of (R)-[(11)C]PK11195 was calculated using receptor parametric mapping in combination with supervised cluster analysis to extract the reference tissue input function. Increased binding of (R)-[(11)C]PK11195 with aging was found in frontal lobe, anterior and posterior cingulate cortex, medial inferior temporal lobe, insula, hippocampus, entorhinal cortex, thalamus, parietal and occipital lobes, and cerebellum. This indicates that activated microglia appear in several cortical and subcortical areas during healthy aging, suggesting widespread neuronal loss.

    We investigate the relationship between age and the five dimensions of time perspective measured by the Zimbardo Time Perspective Inventory (ZTPI) (past negative, past positive, present hedonistic, present fatalistic, and future). Time perspective is related to well-being, decision-making, level of development, and many other psychological issues. Hence, the existence of a systematic relationship between time perspective and age should be considered in all studies for which time is a relevant variable. However, no specific research about this has been conducted. We collected 407 papers that referenced the ZTPI between 2001 and 2015. From those, 72 studies met our inclusion criteria. They included 29,815 participants from 19 countries whose age spans most phases of adulthood (from 13.5 to 75.5 years, mean 28.7). We analyzed these studies adapting meta-analytical techniques. We found that present hedonistic and past negative dimensions are negatively related to aging with partial eta squared effect sizes of roughly 0.15. Our results have implications for the design of studies related to time as our findings highlight the importance of taking into account the differences associated with age. PMID:28261119

    2017-01-01

    Recently, the role of food and nutrition in preventing or delaying chronic disability in the elderly population has received great attention. Thanks to their ability to influence biochemical and biological processes, bioactive nutrients are considered modifiable factors capable of preserving a healthy brain status. A diet rich in vitamins and polyphenols and poor in saturated fatty acids has been recommended. In the prospective of a healthy diet, cooking methods should be also considered. In fact, cooking procedures can modify the original dietary content, contributing not only to the loss of healthy nutrients, but also to the formation of toxins, including advanced glycation end products (AGEs). These harmful compounds are adsorbed at intestinal levels and can contribute to the ageing process. The accumulation of AGEs in ageing (“AGE-ing”) is further involved in the exacerbation of neurodegenerative and many other chronic diseases. In this review, we discuss food's dual role as both source of bioactive nutrients and reservoir for potential toxic compounds—paying particular attention to the importance of proper nutrition in preventing/delaying Alzheimer's disease. In addition, we focus on the importance of a good education in processing food in order to benefit from the nutritional properties of an optimal diet. PMID:28168012

Differences create challenges, but with understanding and skillful communication, distinctions become opportunities for growth and excellence. The concept we are exploring is that as a generation we are who we are because of what was going on in our world during our formative years. We find that just naming ourselves aspart ofa group is a good starting point. The objective of this article is to identify characteristics of various age groups and to present ways to promote harmony and to maximize performance through practical management techniques. The goal is to better understand ourselves and each other so that our work is more productive and rewarding.

    Shanxi aged vinegar is one of the most famous Chinese traditional cereal vinegars produced by spontaneous solid-state fermentation. However, the aroma composition of Shanxi aged vinegar is still ambiguous. The Shanxi vinegars before and after aging were both analyzed by solvent-assisted flavor evaporation combined with gas chromatography-mass spectrometry (GC-MS) as well as gas chromatography-olfactometry (GC-O) in aroma extract dilution analysis. A total of 87 odor-active regions were found by GC-O, and 80 odor-active compounds were identified. By GC-MS/MS, in selected reaction monitoring mode, 30 important identifications were quantitated using authentic standards. In comparison, the aroma molecules for the vinegars before and after aging were almost the same; only their levels were altered, with mostly the esters and some compounds that produce pungent smells being lost and the levels of those from the Maillard reaction, especially the pyrazines (e.g., tetramethylpyrazine), being greatly increased. As for the aged vinegar, the compounds found to have high flavor dilution factors (>128) were 3-(methylthio)propanal, vanillin, 2,3-butanedione, tetramethylpyrazine, 3-methylbutanoic acid, γ-nonalactone, guaiacol, 3-(methylthio)propyl acetate, dimethyl trisulfide, phenylacetaldehyde, 2-ethyl-6-methylpyrazine, 2-acetylpyrazine, 2,3-dimethylpyrazine, furfural, and 3-hydroxy-2-butanone. However, the aroma compounds found at high concentrations (>25 μg/L) in the aged vinegar were acetic acid, followed by 2,3-butanedione, furfural, 3-hydroxy-2-butanone, tetramethylpyrazine, furfuryl alcohol, and 3-methylbutanoic acid.

    Aging and digitalisation are important trends which have their impact on information accessibility. Accessible information about products and services is of crucial importance to ensure that all citizens can participate fully as active members of society. Senior citizens who have difficulties using new media run the risk of exclusion in today's information society. Not all senior citizens, however, encounter problems with new media. Not by a long shot. There is much to be said for 'aged heterogeneity', the concept that individual differences increase as people age. In two explorative qualitative case studies related to accessible health information--an important issue for senior citizens--that were conducted in the Netherlands, variables such as gender, education level and frequency of internet use were therefore included in the research design. In this paper, the most important results of these case studies will be discussed. Attention will be also paid to complementary theories (socialisation, life stages) which could explain differences in information search behaviour when using old or new media.

    Although functional organ stem cells persist in the old, tissue damage invariably overwhelms tissue repair, ultimately causing the demise of an organism. The poor performance of stem cells in an aged organ, such as skeletal muscle, is caused by the changes in regulatory pathways such as Notch, MAPK and TGF-β, where old differentiated tissue actually inhibits its own regeneration. This perspective analyzes the current literature on regulation of organ stem cells by their young versus old niches and suggests that determinants of healthy and prolonged life might be under a combinatorial control of cell cycle check point proteins and mitogens, which need to be tightly balanced in order to promote tissue regeneration without tumor formation. While responses of adult stem cells are regulated extrinsically and age-specifically, we put forward experimental evidence suggesting that embryonic cells have an intrinsic youthful barrier to aging and produce soluble pro-regenerative proteins that signal the MAPK pathway for rejuvenating myogenesis. Future identification of this activity will improve our understanding of embryonic versus adult regulation of tissue regeneration suggesting novel strategies for organ rejuvenation. Comprehensively, the current intersection of aging and stem cell science indicates that if the age-imposed decline in the regenerative capacity of stem cells was understood, the debilitating lack of organ maintenance in the old could be ameliorated and perhaps, even reversed.

    Aging is an inevitable and progressive biological process involving dysfunction and eventually destruction of every tissue and organ. This process is driven by a tightly regulated and complex interplay between genetic and acquired factors. Klotho is an antiaging gene encoding a single-pass transmembrane protein, klotho, which serves as an aging suppressor through a wide variety of mechanisms, such as antioxidation, antisenescence, antiautophagy, and modulation of many signaling pathways, including insulin-like growth factor and Wnt. Klotho deficiency activates Wnt expression and activity contributing to senescence and depletion of stem cells, which consequently triggers tissue atrophy and fibrosis. In contrast, the klotho protein was shown to suppress Wnt-signaling transduction, and inhibit cell senescence and preserve stem cells. A better understanding of the potential effects of klotho on stem cells could offer novel insights into the cellular and molecular mechanisms of klotho deficiency-related aging and disease. The klotho protein may be a promising therapeutic agent for aging and aging-related disorders.

    The purpose of this design calculation is to revise and update the previous criticality calculation for the Aging Facility (documented in BSC 2004a). This design calculation will also demonstrate and ensure that the storage and aging operations to be performed in the Aging Facility meet the criticality safety design criteria in the ''Project Design Criteria Document'' (Doraswamy 2004, Section 4.9.2.2), and the functional nuclear criticality safety requirement described in the ''SNF Aging System Description Document'' (BSC [Bechtel SAIC Company] 2004f, p. 3-12). The scope of this design calculation covers the systems and processes for aging commercial spent nuclear fuel (SNF) and staging Department of Energy (DOE) SNF/High-Level Waste (HLW) prior to its placement in the final waste package (WP) (BSC 2004f, p. 1-1). Aging commercial SNF is a thermal management strategy, while staging DOE SNF/HLW will make loading of WPs more efficient (note that aging DOE SNF/HLW is not needed since these wastes are not expected to exceed the thermal limits form emplacement) (BSC 2004f, p. 1-2). The description of the changes in this revised document is as follows: (1) Include DOE SNF/HLW in addition to commercial SNF per the current ''SNF Aging System Description Document'' (BSC 2004f). (2) Update the evaluation of Category 1 and 2 event sequences for the Aging Facility as identified in the ''Categorization of Event Sequences for License Application'' (BSC 2004c, Section 7). (3) Further evaluate the design and criticality controls required for a storage/aging cask, referred to as MGR Site-specific Cask (MSC), to accommodate commercial fuel outside the content specification in the Certificate of Compliance for the existing NRC-certified storage casks. In addition, evaluate the design required for the MSC that will accommodate DOE SNF/HLW. This design calculation will achieve the objective of providing the

    Full Text Available Aging is increasingly regarded as an independent risk factor for development of cardiovascular diseases such as atherosclerosis and hypertension and their complications (e.g. MI and Stroke. It is well known that vascular disease evolve over decades with progressive accumulation of cellular and extracellular materials and many inflammatory processes. Metabolic syndrome, obesity and diabetes are conventionally recognized as risk factors for development of coronary vascular disease (CVD. These conditions are known to accelerate ageing process in general and vascular ageing in particular. Adverse events during intrauterine life may programme organ growth and favour disease later in life, popularly known as, ′Barker′s Hypothesis′. The notion of fetal programming implies that during critical periods of prenatal growth, changes in the hormonal and nutritional milieu of the conceptus may alter the full expression of the fetal genome, leading to permanent effects on a range of physiological.

    Old age, with its inevitable succession of bereavement and loss, is a difficult time of life, and is often a cause of suffering on both an individual and a family level. The crises of aging, such as retirement, dependency or old age, bring a person face-to-face with their finiteness, creating anxiety and raising questions related to death. These are times of intense instability, which can lead either to personal growth through a process of adaptation and a rebuilding of one's self-image, or to a dysfunctional approach and an increase in suffering, through resistance to change. Through its work, the therapist aims to assist the elderly person to cope more serenely with the frustrations of the external reality and to come to terms with their future death.

    Full Text Available For healthy and independent older adults, aging in place can be seen as identical to any other adult living at home. Little is known about how frail seniors, particularly those who speak a minority language, manage the challenges of aging in place. The present qualitative descriptive study explores the strategies that Canadian French-speaking seniors have put in place to counter their loss of independence and promote their ability to stay in their home. Semistructured individual interviews were conducted with 39 older adults and transcribed, followed by content analysis to identify common themes related to study objectives. Six themes emerged in response to strategies described for aging in place. Findings reveal the limited extent to which language issues were perceived as a barrier by participants. In conclusion, the results of this study provide us with fruitful insights to guide community nursing practice, future research, and public policy.

    Immune checkpoint inhibitors (ICIs) are based on the understanding that there are multilayered checks and balances which can be manipulated to unleash already existing, but paralyzed, immune responses to cancer. These agents are safer and more efficacious than classic cytotoxic drugs making them a very attractive therapeutic option, especially in older adults. Current available data do not suggest significant age-associated differences in the clinical profile of ICIs. It must be noted, however, that there is still relatively little information on the use of ICIs in adults over 75years of age and aging is associated with a decline in the immune system or "immunosenescence" which theoretically can reduce the efficacy of these immune based therapies. In this paper, we review the mechanism of action of ICIs, current clinical data on their use in older adults, and age-associated immune changes that might have a direct impact on their activity in this population. We chose to focus on mainly adaptive cellular immunity, and especially on components of the immune system that are implicated directly in the immune checkpoint process.

    Autophagy is a cell self-digestion process via lysosomes that clears "cellular waste",including aberrantly modified proteins or protein aggregates and damaged organelles.Therefore,autophagy is considered a protein and organelle quality control mechanism that maintains normal cellular homeostasis.Dysfunctional autophagy has been observed in ageing tissues and several ageing-associated diseases.Lifespan of model organisms such as yeast,worms,flies,and mice can be extended through promoting autophagy,either by genetic manipulations such as over-expression of Sirtuin 1,or by administrations of rapamycin,resveratrol or spermidine.The evidence supports that autophagy may play an important role in delaying ageing or extending lifespan.In this review,we summarize the current knowledge about autophagy and its regulation,outline recent developments ie the genetic and pharmacological manipulations of autophagy that affects the lifespan,and discuss the role of autophagy in the ageing-related diseases.ow in Center for Neurodegenerative and Neuroimmunologic Diseases,Department of Neurology,University of Medicine and Dentistry of New Jersey-Robert Wood Johnson Medical School,Piscataway,NJ 08854,USA

  19. Accelerated aging syndromes, are they relevant to normal human aging?

    Dreesen, Oliver; Stewart, Colin L

    2011-09-01

    Hutchinson-Gilford Progeria (HGPS) and Werner syndromes are diseases that clinically resemble some aspects of accelerated aging. HGPS is caused by mutations in theLMNA gene resulting in post-translational processing defects that trigger Progeria in children. Werner syndrome, arising from mutations in the WRN helicase gene, causes premature aging in young adults. What are the molecular mechanism(s) underlying these disorders and what aspects of the diseases resemble physiological human aging? Much of what we know stems from the study of patient derived fibroblasts with both mutations resulting in increased DNA damage, primarily at telomeres. However, in vivo patients with Werner's develop arteriosclerosis, among other pathologies. In HGPS patients, including iPS derived cells from HGPS patients, as well as some mouse models for Progeria, vascular smooth muscle (VSM) appears to be among the most severely affected tissues. Defective Lamin processing, associated with DNA damage, is present in VSM from old individuals, indicating processing defects may be a factor in normal aging. Whether persistent DNA damage, particularly at telomeres, is the root cause for these pathologies remains to be established, since not all progeroid Lmna mutations result in DNA damage and genome instability.

    In this paper, I described clinical and basic problems on neurology of the aged patients. These studies have been done in various institutions with many co-workers. 1) A PET study revealed some age differences on CBF, CMRO2, or CMRgl. But these results are not so rigid in which much of individual variations should be considered in interpretation. Calendar age is not always compatible to biological age. 2) Saccular aneurysms in the brain artery were found in 7.3% of 1200 routine autopsy series of the aged subjects. Aneurysms with external diameter exceeding 6 mm had been fatally ruptured in 14 (78%) of 18 subjects. 3) Variations of the pyramidal crossing are found responsible for bizarre clinical manifestations. Non-crossing component was more prominent in the right pyramidal tract; consequently, right pyramidal tracts including ventral and lateral one seemed to have more extensive representation in the spinal cord level. 4) I123-IMP SPECT study showed a reduced uptake in the area 4 or area 4-6 of the ALS patients. 5) I introduced a new simplified Wartenberg's maneuver, which is useful for detection of subtle pyramidal dysfunctions. 6) Cases with central pontine myelinolysis and those of paraneoplastic syndrome were presented with an emphasis on their patho-chemical mechanisms. 7) Lewis-Sumner syndrome showing multifocal persistent conduction block is not rare in the aged, in which we have already had some useful therapeutic methods. 8) Dementia complicated with neurodegenerative disease was discussed on its clinical and chemical features of mental disturbances. In ALS-dementia, CSF-homovanilic acid reduced significantly than in the control and L-dopa was effective in some patients. 9) Vascular and Alzheimer-type dementias were presented and discussed on their pathogenetic mechanism according to our recent studies with review of literature.

This allows a quick estimate as to the types of procedures that the patient would need to have the best results. Procedures that are presently used for facial rejuvenation include laser, chemical peels, suture lifts, fillers, modified facelift and full facelift. The physician is already using his best judgment to determine which procedure would be best for any particular patient. This classification may help to refine these decisions.

  8. Atypical aging in Down syndrome.

    2013-01-01

    At present, there may be over 210,000 people with Down syndrome (DS) over the age of 55 in the United States (US) who have significant needs for augmented services due to circumstances related to ordinary and/or pathological aging. From 1979 through 2003, the birth prevalence of DS rose from 9.0 to 11.8 (31.1%) per 10,000 live births in 10 representative US regions. This increase, largely due to women conceiving after age 35, portends an ever-growing population of people with DS who may be subject to pathogenic aging. Whereas Trisomy 21 is one of the most widespread genetic causes of intellectual disability (ID), it still is one of the least understood of all genetic ID syndromes. While longevity in people with DS has improved appreciably in as modest a period as 30 years, age-specific risk for mortality still is considerably increased compared both with other people with ID or with the typically developing population. The penetrance of the phenotype is widely distributed, even though a consistent genotype is assumed in 95% of the cases. Some, but not all body systems, exhibit signs of premature or accelerated aging. This may be due to both genetic and epigenetic inheritance. We now know that the long-term outcome for people with DS is not as ominous as once contemplated; a number of people with DS are living into their late 60s and 70s with few if any major signs of pathogenic aging. Alzheimer's disease (AD), a devastating disease that robs a person of their memory, abilities and personality, is particularly common in elder adults with DS, but is not a certainty as originally thought, some 20% to 30% of elder adults with DS might never show any, or at most mild signs of AD. DS has been called a mature well-understood syndrome, not in need of further research or science funding. We are only beginning to understand how epigenetics affects the phenotype and it may be feasible in the future to alter the phenotype through epigenetic interventions. This chapter is

  11. Universal Design: A Step toward Successful Aging

    Directory of Open Access Journals (Sweden)

    Kelly Carr

    2013-01-01

    Full Text Available The concept of aging successfully has become increasingly important as demographics shift towards an aging population. Successful aging has been defined to include (1 a low probability of disease and disease-related disability; (2 a high level of physical and cognitive functioning; and (3 an active engagement in life. The built environment can create opportunities or constraints for seniors to participate in social and productive activities. Universally designed spaces are more easily accessed and used by a spectrum of people without specialized adaptations. Thus, a universally designed environment creates opportunities for older adults to participate in these activities without the stigmatization associated with adapted or accessible designs. Providing older adults with specific universal design options (e.g., lever handle faucets has the potential to increase the ease of completing activities of daily living, which promotes a continual engagement in life. Literature regarding universal design is promising; however, its theory requires further attention from professionals designing the built environment, evidence of the significance of its application from academics, and the embracement of its core principles from society. Overall, universal design has the potential to provide a stepping stone toward successful aging.

    Aging is a natural consequence of a society developing process. Although many adults retain good hearing as they aging, hearing loss related with age-presbycusis which can vary in severity from mild to substantial is common among elderly persons. There are a number of pathophysiological processes underlying age-related changes in the auditory system as well as in the central nervous systems. Many studies have been dedicated to the illustration of risk factors accumulating presbycusis such as heritability, environment factors, medical conditions, free radical (reactive oxygen species, ROS) and damage of mitochondrial DNA. Left untreated, presbycusis can not only lead sufferers to reduced quality of life, isolation, dependence and frustration, but also affect the healthy people around. These can be partly corrected using hearing aids, but it is not enough, more and more strategies of treatment based on the findings associating with presbycusis should be added rather than using single hearing aids. We review here the pathophysiology; heritability, susceptibility genes and other risk factors including environmental, medical, especially free radical (ROS) and damage of mitochondrial DNA; and some strategies of treatment, as well as promising rehabilitations associating with presbycusis.

    Between the ages of 30 and 80, the physiological abilities decrease: muscular, cardiovascular, respiratory, neurological, etc. The consequences on sports activities are obvious: limitation of the performance per se, quantitatively as well as qualitatively as well as the ability to recover. This is combined with a danger: coronary atherosclerosis responsible for 90 p. cent of the sudden deaths episodes seen in sports, in men over the age of 40/50. Even in France, a country that is not traditionally sports oriented (Pierre de Coubertin and a few occasional champions are really exceptions masking the non-existent sports activities in school)-sports have become a society phenomenon, on a par with the development of leisure, a younger retirement age, increased unemployment and the ageing of the population. Twelve millions of french people hold a sport license and more that twenty millions practice a sport more or less regularly. As epidemiologic studies are in a great majority as well as secondary prevention, it is possible to assert that there is no topic more frequently discussed today than that of physical activities in cardiology consultations. Often, french physicians are not well equipped to answer questions of provide judicious advice: because, very often, these physicians do not practice any sport and/or they are not convinced of the advantages of physical exercise and unfamiliar with the specific restrictions of each sport. In addition, they cannot perform a stress-test in their office--as in this domaine our country is also far behind.

  14. Active ageing as lifestyle on Croatian islands

    2014-01-01

    Full Text Available The main feature of Croatian islands, in addition to their beautiful nature, is the fact that they are demographically and sociologically one of the most threatened areas affected by ageing. The ageing of the island population is the result of a long-term depopulation caused by the continuous emigration of the younger working-active population over the past hundred years, but also by the retirement return migration in the last thirty years. The most critical situation is on small islands where the majority of population is aged over 60 and this has a significant impact on all aspects of island life. The research conducted on small islands in the Šibenik archipelago in 2011 has shown that older people live alone, with no significant health problems limiting their daily activities, in their own households (homes, on modest pensions, and many of them supplement their income through agriculture. They very often financially help their children, who live mostly in nearby mainland cities. The necessity of self-reliance, due to the lack of younger generations, forces the inhabitants of Croatian island to lead an active life until their old age. Although they are no longer actively employed, they still continue to contribute significantly to the family and society through their involvement in various community activities.

    Evolving definitions of frailty, and improved understanding of molecular and physiological declines in multiple systems that may increase vulnerability in frail, older adults has encouraged investigators from many disciplines to contribute to this emerging field of research. This article reports on the results of the 2004 American Geriatrics Society/National Institute on Aging conference on a Research Agenda on Frailty in Older Adults, which brought together a diverse group of clinical and basic scientists to encourage further investigation in this area. This conference was primarily focused on physical and physiological aspects of frailty. Although social and psychological aspects of frailty are critically important and merit future research, these topics were largely beyond the scope of this meeting. Included in this article are sections on the evolving conceptualization and definitions of frailty; physiological underpinnings of frailty, including the potential contributions of inflammatory, endocrine, skeletal muscle, and neurologic system changes; potential molecular and genetic contributors; proposed animal models; and integrative, system biology approaches that may help to facilitate future frailty research. In addition, several specific recommendations as to future directions were developed from suggestions put forth by participants, including recommendations on definition and phenotype development, methodological development to perform clinical studies of individual-system and multiple-system vulnerability to stressors, development of animal and cellular models, application of population-based studies to frailty research, and the development of large collaborative networks in which populations and resources can be shared. This meeting and subsequent article were not meant to be a comprehensive review of frailty research; instead, they were and are meant to provide a more-targeted research agenda-setting process.

    Pneumonia is the third largest cause of death in Japan. Chest physicians have been struggling to improve the outcome of pneumonia treatment in acute care settings. However, a poor long-term prognosis after pneumonia has not been well recognized. Furthermore, the factors related to the poor prognosis, especially the possible involvement of senescence-related disability, have not been identified. In this study, long-term outcomes after discharge from hospital were retrospectively analyzed to identify factors related to the poor long-term prognosis. Outcomes of 958 pneumonia patients who were discharged from South Miyagi Medical Center (Miyagi, Japan) from June 1, 2008 to March 31, 2014 were determined through patient surveys or medical record reviews on September 26, 2014. Survival curves were constructed and compared according to various factors. Multivariate analysis revealed that all levels of decrease in physical activity, an age of 80 years old or more, the most severe status in Japanese Respiratory Society pneumonia severity grading system, the presence of antibiotic-resistant bacteria, and comorbid malignancy significantly reduced long-term survival. The effects of dementia, neuromuscular disease, heart disease, and nursing care residency on long-term survival were detected only with univariate analysis. Physical activity influenced the acute-phase and the long-term prognosis of pneumonia. This report provides information to assist physicians in giving better suggestions to disabled older patients when choosing pneumonia treatment options. In conclusion, we propose that death related to pneumonia can be prevented in the same way as non-communicable diseases by improving physical activity.
