Understanding the complexity of aging is of utmost importance. This can now be addressed by the novel and powerful approach of metabolomics. However, to date, only a few metabolic studies based on large samples are available. Here, we provide novel and specific information on age-related metabolite concentration changes in human homeostasis. We report results from two population-based studies: ...
Random Item Generation tasks (RIG) are commonly used to assess high cognitive abilities such as inhibition or sustained attention. They also draw upon our approximate sense of complexity. A detrimental effect of aging on pseudo-random productions has been demonstrated for some tasks, but little is as yet known about the developmental curve of cognitive complexity over the lifespan. We investiga...
This paper assesses empirically the relationship between GDP per capita growth uctuations and the age structure and intensity of human capital across developed and developing countries We estimate a spatial vector autoregressive model of income dynamics where the economic distance between countries is de ned on their similarity in measures of human capital and its distribu tion across age group...
Historians will refer to our time as the Age of Information. While information is indeed important, we think that the creative exchange of information, the interactive process between humans and computers will be the foremost challenge of the 21st century. Human computer interaction (HCI) lies at the crossroads of many academic areas including artificial intelligence, psychology, computer visio...
انتقال dna به داخل یاخته های پستانداران بوسیله دندروزومها، یکی از جدیدترین روشهای انتقال dna به داخل یاخته محسوب می شود که مزایای زیادی نسبت به روشهای قدیمی تر مانند فسفات کلسیم، دکستران، لیپوزومها، دندریمرها و الکتروپوریشن دارند. دندروزومها، ارزان، خنثی و غیر سمی هستند. یاخته های اندوتلیال رگ بندناف انسان، نقش مهمی در خونسازی، عملکرد رگها و ایمنی زایی دارند با توجه به این اعمال فیزیولو...
purpose a metabolic abnormality such as obesity is a major obstacle in the maintenance of the human health system and causes various chronic diseases including type 2 diabetes, hypertension, cardiovascular diseases, as well as various cancers. this study was designed to summarize the recent scientific knowledge regarding the anti-obesity role of curcumin (diferuloylmethane), which is isolated f...
Adolescent uptake of human papillomavirus (HPV) vaccine remains low. We evaluated HPV vaccine uptake patterns over 2008-2011 by race/ethnicity, poverty status, and the combination of race/ethnicity and poverty status, utilizing National Immunization Survey-Teen data. Minority and below-poverty adolescents consistently had higher series initiation than white and above-poverty adolescents.
During the 1997 Fédération Internationale des Sociétés d’Aviron World Junior Rowing Championships, anthropometric data on 383 male junior rowers were assessed. With 430 participating athletes, the sample represented 89% of the population. In addition to age, 27 dimensions were measured: body mass, six heights or lengths, four breadths, 10 girths, and six skinfolds. The elite male junior rowers ...
Facial aging, a new dimension that has recently been added to the problem of face recognition, poses interesting theoretical and practical challenges to the research community. The problem which originally generated interest in the psychophysics and human perception community, has recently found enhanced interest in the computer vision community. How do humans perceive age ? What constitutes an...
