Background: Hirsutism is defined as the presence of terminalhairs with a male-like pattern in women, due to the increasedlevels of androgens or increased responses of the target organs toandrogens. Facial hirsutism has a negative effect on the quality oflife in female patients. Among the many therapeutic modalitie...

In this study we addressed a question of whether experimental manipulations that increase life span also reduce physical activity and molecular oxidative damage. We used three phenotypes of male and female Pyrrhocoris apterus that survive for different lengths of time, diapausing insects, reproductive insects and insects from which the corpus allatum, the source of juvenile hormone, was surgica...

this study was conducted to evaluate a temperature regime ranged from 15 to 30°c on survival, growth, life span and reproductive traits (reproductive period, clutch number, offspring number) of phallocryptus spinosa from iran. newly hatched nauplii (n= 200 and 3 replicates per each treatment) were allocated into containers and maintained at various temperature regimes (at 15, 20, 25 and 30˚c). ...

Oxygen at high pressure (OHP) and X-irradiation can interact in the fruit fly Drosophila melanogaster to potentiate toxic actions characteristic of one agent alone. 1000 kvp X-irradiation in doses of 30, 60, and 75 kr accelerated the acute immobilization of young male Drosophila by oxygen at 7.8 atm, up to rates twice that observed with such oxygen pressure alone. X-irradiation alone in these d...

Biotin deficiency is associated with fetal malformations and activation of cell survival pathways in mammals. In this study we determined whether biotin status affects life span, stress resistance, and fertility in the fruit fly Drosophila melanogaster. Male and female flies of the Canton-S strain had free access to diets containing 6.0 (control), 4.8, 2.5, or 0 pmol biotin/100 mg. Biotin conce...
