Autobiographical memory, or memory for personal experiences, allows individuals to define themselves and construct a meaningful life story. Current research aims to review the definition and theories of autobiographies memory and how it usually changes or abnormally in older adults. Base on studies, as we grow older autobiographical memory drops off, also semantic memory changes a little or som...
Objectives: In this paper, aging with its different dimensions is discussed. The characteristics of elderly's life in relation to individual, social, and changes meet aging together with attitudes toward it and major components of elderly are explained. Disease and burden of disease of aging as a central to the areas of Health and Health Economics will be emphasized. The influential factors on ...
background: the antioxidant components have been identified in some pine species. antioxidant properties of proantocyanidins reduce free radicals induced by dna fragmentation and lipid proxidation and also proanthocyanidines could curb lipid peroxidation. objective: in this study, we analyzed different parts of pinus eldarica (bark, seed and needle) and assessed their antioxidant contents. meth...
Transition seeds exhibit a good tradeoff between sensitivity and specificity for homology search in both coding and non-coding regions. But, identifying good transition seeds is extremely hard. We study the hit probability of high-order seed patterns. Based on our theoretical results, we propose an efficient method for ranking transition seeds for seed design.
introduction: raising the knowledge of skeletal and soft tissue changes with aging has been highly essential due to an increasing demand for aesthetic facial surgery following aging. the aim of this study is to evaluate the three dimensional computed tomographic images and process of changes in mandible with aging. materials and methods: in this descriptive study, the facial ct scans were obtai...
in order to investigate the role of bacillus cogulans on yield of two forage corn cultivars, an experiment carried out at agricultural research center of tehran province during 2009-2010. the experiment design consisted of three randomized complete blocks in a factorial arrangement. investigated treatments consisted of the kind of phosphorus and cultivar. the phosphorus factor included of the a...
skin aging is a continuous process that exhibits fine and deep wrinkles, thin and transparent skin, loss of underlying fat, dry skin and itch, following decreased collagen and elastin synthesis. both extrinsic and intrinsic agents are considered in the pathogenesis on skin aging. extrinsic factors such as sun exposure, windy and dry weather, nutrition, and lifestyle may induce premature aging,...
miRNAs have recently been shown to play a significant role in human aging. However, data demonstrating the effects of aging-related miRNAs in human mesenchymal stem cells (hMSCs) are limited. We observed that hMSC differentiation decreased with aging. We also identified that miR-10a expression was significantly decreased with age by comparing the miRNA expression of hMSCs derived from young and...
Changes in the functional connectivity (FC) of large-scale brain networks are a prominent feature of brain aging, but defining their relationship to variability along the continuum of normal and pathological cognitive outcomes has proved challenging. Here we took advantage of a well-characterized rat model that displays substantial individual differences in hippocampal memory during aging, unco...
BACKGROUND Although global brain structure is highly heritable, there is still variability in the magnitude of genetic influences on the size of specific regions. Yet, little is known about the patterning of those genetic influences, i.e., whether the same genes influence structure throughout the brain or whether there are regionally specific sets of genes. METHODS We mapped the heritability ...
