Changes in Lipid Peroxidation under Exposure to Electromagnetic Radiation of Nonthermal Intensity in the Prenatal Period

Biophysics - This study focused on the redox homeostasis in the lenses of 20- and 30-day-old chinchilla rabbit kits exposed to a combination of hypoxia and electromagnetic radiation at a nonthermal...     

Correlation between Drosophila population sizes and solar activity parameters

The relationships between the time series of the changes in the sizes of experimental Drosophila melanogaster populations at the preimaginal stage and three heliogeophysical indices (Wolf numbers, 10.7-cm radio flux intensity, and the K _p index of geomagnetic activity) have been analyzed. The results demonstrate a significant relationship between the population dynamics and heliogeophysical factors and dependence of this relationship on the phase of the 11-year solar activity cycle. Factors related to solar activity may stimulate female fertility and egg survival.     

Intensity of Lipid Peroxidation in the Crystalline Lens of the Rabbit <Emphasis Type="Italic">Chinchilla brevicaudata</Emphasis> Exposed to Hypoxia and Radiation in the Prenatal Period

We address the redox homeostasis in the crystalline lens of the rabbit pups (aged 20 and 30 days) exposed to a combined effect of non-ionizing electromagnetic radiation (EMR) and hypoxia during their prenatal development. The intensity of lipid peroxidation (LPO) in the lens was in the focus of this study, being evaluated by a level of malondialdehyde (MDA), a final LPO product. It was established that prenatal exposure to 460-MHz non-ionizing EMR combined with hypoxia intensifies LPO. The obtained results allow some conclusions to be drawn about the mechanisms of antioxidant defense in relevant biological tissues. The necessity of further studies to prove the revealed tendencies is substantiated.
