The yeast Saccharomyces cerevisiae has a limited life span that can be measured by the number of times individual cells divide. Several genetic manipulations have been shown to prolong the yeast life span. However, environmental effects that extend longevity have been largely ignored. We have found that mild, nonlethal heat stress extended yeast life span when it was administered transiently ea...

ALT (accelerated life tests) are widely used to provide quickly the information about life distributions of products. Life data at elevated stresses are extrapolated to estimate the life distribution at design stress. The existing estimation methods are efficient and easy to implement—given sufficient life data. However, ALT frequently results in few or no failures at low-level stress, making i...

Although substantial research has examined the effects of stress on cognition, much of this research has focused on acute stress (e.g. manipulated in the laboratory) or chronic stress (e.g. persistent interpersonal or financial difficulties). In contrast, the effects of recent life stress on cognition have been relatively understudied. To address this issue, we examined how recent life stress i...

Recently, the World Health Organization has made the need for countries to improve the school context and enhance the health of students at the school in terms of quality of life. This study aimed to determine the relation between improvement, adventure, social solidarity and opportunity with perceived stress among students. During the correlational qualitative research, among the population of...
