As a tool for measuring the aging process, life span has been invaluable in dissecting the genes that modulate longevity. Studies over the past few decades have identified several hundred genes that can modify life span in model organisms such as yeast, worms, and flies. Yet, despite this vast amount of research, we still do not fully understand how the genes that affect life span influence how...

The life span of Caenorhabditis elegans is controlled by signaling between the germline and the soma. Germ cell removal extends life span by triggering the activation of the DAF-16/FOXO transcription factor in the intestine. Here we analyze microRNA function in C. elegans aging and show that the microRNA mir-71 functions to mediate the effects of germ cell loss on life span. mir-71 is required ...

An individual's happiness is closely related to their family life as the institution in which they spend most of life. Capitalizing on data from 2018 China Family Panel Studies, this study investigates relationship between economic standing (measured by household income and homeownership) processes marital status childlessness), well children's characteristics gender composition children adult ...

Background The initial years of life particularly the first two years are regarded as the most important brain development period. The development of children is an important determinant of health throughout the whole of life. We aimed to evaluate an educational program to improve the fine motor skills of 18-month-old ...

the survival, growth, reproductive and life span characteristics of phallocryptus spinosa were studied at different temperatures in the laboratory. three replicates of 200 newly hatched nauplii were transferred to culture containers at 15, 20, 25 and 30˚c. the larvae were fed with unicellular algae dunaliella tertiolecta and chemically treated yeast known as lansy pz. survival and growth rate o...
