Trehalose is a disaccharide of glucose found in diverse organisms and is suggested to act as a stress protectant against heat, cold, desiccation, anoxia, and oxidation. Here, we demonstrate that treatment of Caenorhabditis elegans with trehalose starting from the young-adult stage extended the mean life span by over 30% without ...

The impact of a total laryngectomy on an individual's life has primarily been measured from a male viewpoint reflecting the demographics of a diagnosis of laryngeal cancer. A small number of studies have looked specifically at females, but very few are comparison studies. Consequently, there is little consistent research regarding ...

The miR-17-92 cluster encoding 6 single mature miRNAs was identified a couple of years ago to contain the first oncogenic miRNAs. Now, one of these 6 miRNAs, miR-19 has been identified as the key responsible for this oncogenic activity. This in turn reduces PTEN levels and in consequence activates the ...

The standard practice in cost-effectiveness analyses of health care is to assign a linear value to increasing lifetime gains. The aim of the current study was to examine the possible existence of non-linear utility for short life extensions. A representative sample of the Norwegian population, aged 40-59 years (n=2402), was ...

Due to its many advantages, the nematode worm Caenorhabditis elegans (C. elegans) is commonly employed as a convenient model for aging studies as well as for testing life span effects of chemical compounds. However, some challenges exist in the context of such life span studies, particularly in relation to generation ...

People want to be wealthy, attractive, young, and healthy, and they integrate these wishes into most of their activities. As a result, aging processes are somewhat postponed in the human organism. Both average life expectancy and expected life in good health increase by 0.15-0.2 years every year in most developed ...

In some population groups, human life expectancy is much higher compared to the average in the population, which can provide new hints to postpone aging and prolong life. Studies show that university professors have a later onset of age-related diseases compared with most population groups. Their productivity mostly increases up ...

Aging is characterized by general physiological decline over time. A hallmark of human senescence is the onset of various age-related afflictions including neurodegeneration, cardiovascular disease and cancer. Although environmental and stochastic factors undoubtedly contribute to the increased incidence of disease with age, recent studies suggest that intrinsic genetic determinants govern ...

Maternal effects occur when the maternal phenotype influences that of the offspring in addition to the effects of maternal genes, and may have a considerable influence on offspring parasite resistance. These effects, and the effects of early levels of reproduction and parasite resistance, may persist into later life and even ...

Comparative genomics of representative basal metazoans leaves little doubt that the most recent common ancestor to all modern metazoans was morphogenetically complex. Here, we support this interpretation by demonstrating that the demosponge Amphimedon queenslandica has a biphasic pelagobenthic life cycle resembling that present in a wide range of bilaterians and ...

This paper introduces a quadratic fractional age assumption which makes the force of mortality and survival function continuous at all ages. The necessary and sufficient condition for the assumption to be valid is derived. Important life table parameters are estimated and applications are shown using several life table data.

Life expectancy, or the estimated average age of death, is among the most basic measures of a population's health. However, monitoring differences in life expectancy among sociodemographically defined populations has been challenging, at least in the United States (US), because death certification does not include collection of markers of socioeconomic ...

Calorie restriction (CR) is a regimen of reduced food intake that, although the underlying mechanism is unknown, in many organisms leads to life span extension. Podospora anserina is one of the few known ageing filamentous fungi and the ageing process and concomitant degeneration of mitochondria have been well-studied. CR in ...

In recent years, there has been increasing demand for health indicators at small area level to support monitoring and planning. This study investigates the use of a small area geography, Middle Layer Super Output Areas (MSOAs) for the estimation and comparison of disability-free life expectancy (DFLE) in England. Using death ...

Senescence has been widely detected among mammals, but its importance to fitness in wild populations remains controversial. According to evolutionary theories, senescence occurs at an age when selection is relatively weak, which in mammals can be predicted by adult survival rates. However, a recent analysis of senescence rates found more ...

Studies on aging reflect the losses inherent in the aging process. How the aging process is viewed, either as a loss or as a natural process of living, may affect the adaptation by late-midlife women to life changes. Self-transcendence is a means of broadening one's perspective of the inner being. ...

During the first year of life, infants pass important milestones in language development. We review some of the experimental evidence concerning these milestones in the domains of speech perception, phonological development, word learning, morphosyntactic acquisition, and bilingualism, emphasizing their interactions. We discuss them in the context of their biological underpinnings, ...

Clinical experience shows that the individual significance of olfactory function varies between subjects. In order to estimate these individual differences we developed a questionnaire to study the subjective importance of the sense of smell. Questions were arranged within three subscales: association with olfactory sensations, application of the sense of smell, ...

In the absence of long-term field studies, demographic and reproductive records from animals housed in zoos and research laboratories are a valuable tool for the study of life history variables relating to reproduction. In this study, we analyzed studbook records of more than 2,000 individuals born over a 40-year period ...

Sister chromatid cohesion is essential for cell division. During meiosis, it is also required for proper synapsis of pairs of sister chromatids and for chiasma formation and maintenance. Since mammalian oocytes remain arrested in late prophase for a very long period-up to five decades in humans-the preservation of cohesion throughout ...
