The San Antonio Nathan Shock Center Conferences have attracted international speakers and participants since 1995. This annual conference, held in Bandera, Texas, USA, addresses a different topic in the biology of aging each year. The venue's intimate setting, relatively remote location, and common areas are ideal for a small conference (80Á100 participants), where copious informal intellectual...
Although the typical antioxidant, N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD), ensures high durability and long lifespan for rubber compounds, it generates a highly toxic quinone in water, causing serious environmental pollution. Herein, as an alternative material of 6PPD, we newly introduce eco-friendly amine-functionalized lignin (AL) to be incorporated rubber, which can provide...
discovery that mutations in single genes can modulate aging was not only fascinating but it provided researchers with animal models with which to study aging in cohorts of different aging rates [1-2]. According to the GenAge database [3], at the time of writing, genetic manipulations in 68 genes have been shown to affect lifespan in mice. Among mouse genes in which mutations extend lifespan, a ...

background physical activity is an important component of health in old age that provides personal independence, physical ability, and quality of life. objectives the current study aimed to evaluate physical activity and associated factors among the elderly population in kashan, iran. patients and methods this is a descriptive cross-sectional study. the sample was 400 elderly people (aged more ...
Embedded languages in Haskell benefit from a range of type extensions, such as type families, that are subsumed by dependent types. However, even with those type extensions, embedded languages for data parallel programming lack desirable static guarantees, such as static bounds checks in indexing and collective permutation operations. This observation raises the question whether an embedded lan...
This paper reviews the recent progress in the investigation into how learning can effect evolutionary dynamics after a century of sharply con¤icting views. The results are signi£cant both for theoretical biologists of various stripes and for computer scientists working on computational intelligence and other subdisciplines which often rely on the transfer of biological principles to digital sys...
conclusions reported herbal drugs might be beneficial for further studies for the management of skin aging and aging process. results skin aging begins with whole body aging process and entire body gets cold and dry in elderly. wrinkle formation is highly associated with loss of “skin natural moisture”. in the management, specific food supplements, simple massage therapy as well as herbal drugs...
The Lagrangian equations of motion for massive spinning test particles (tops) moving on a gravitational background using general relativity are presented. The paths followed by tops are nongeodesic. An exact solution for the motion of tops on a Schwarzschild background which allows for superluminal propagation of tops is studied. It is shown that the solution becomes relevant for particles with...
OBJECTIVE To establish whether HIV disease is associated with abnormal levels of age-related brain atrophy, by estimating apparent brain age using neuroimaging and exploring whether these estimates related to HIV status, age, cognitive performance, and HIV-related clinical parameters. METHODS A large sample of virologically suppressed HIV-positive adults (n = 162, age 45-82 years) and highly ...
