Life span extension in Drosophila melanogaster induced by morphine.

The influence of morphine on the life span of Drosophila melanogaster fruit flies has been investigated. Morphine hydrochloride (MH) at concentrations of 0.01, 0.

Life extension in Drosophila maintained under lengthened light/dark regime.

In the present study, we investigated whether the length of light/dark cycle could influence the pre-adult developmental time and adult life span in Drosophila melanogaster. Flies were reared to adulthood and maintained as adults under both 24-h (light/dark 12:12 h) and 48-h (light/dark 24:24 h) cycles. The flies reared during pre-adult stages at the 48-h light/dark cycle had significantly prolonged developmental time compared to those in flies reared at normal 24-h cycle.

Cross-life stage and cross-generational effects of gamma irradiations at the egg stage on Drosophila melanogaster life histories.

The long-term effects of X-irradiation with 0.25, 0.5, 0.

Effect of X-irradiation at larval stage on adult lifespan in Drosophila melanogaster.

The effects of X-ray irradiation at larval stage with doses of 1.2, 2.1, 4.

Variation of mortality rate during the individual annual cycle.

The month of birth was significantly associated with the month of death in 102,265 individuals who died in Kiev during the period 1990-2000. A consistent trend in deaths was revealed, with an excess around the birthday. This excess on the actual anniversary of birth was 44.

Early programming of adult longevity: demographic and experimental studies.

It is supposed that longevity might be programmed by early life exposures. We had carried out demographic and experimental researches for the examination of the possibility of longevity programming. In demographic study, the recorded deaths in Kiev (Ukraine) between 1990 and 2000 (51,503 men and 50,131 women) were used.

Effects of X-irradiation in early ontogenesis on the longevity and amount of the S1 nuclease-sensitive DNA sites in adult Drosophila melanogaster.

The long-term consequences of the X-irradiation of Drosophila melanogaster fruit fly one-hour eggs with doses of 0.25, 0.50, 0.
