The ERs are required for the effects of E2 to be observed thus, a destruction of these receptors can come along with the effects of testicular changes through ageing, thus can help further progress toward their involution process. Other studies investigated the opposite end of the spectrum by ...

light-harvesting complexes leads to the formation of1O2and O2●-, which can be further converted to H2O2and OH●. The production of ROS is enhanced by strong light and also by deceleration of the Calvin cycle [28]. In the dark period, most oxygen radicals are produced by mitochondria [29...
Gametes are plentiful in infected cell monolayers but oocysts are rare (<0.1% of all stages), which is consistent with our sequencing data. To determine whether these oocysts were produced de novo, we labelled newly synthesized DNA using the thymidine kinase analogue, EdU. As reported previously...
Matingbehaviour describes the social interactions involved in joininggametes(that is, eggs andsperm) in the process offertilization. In most marine organisms, planktonic gametes are shed (or broadcast) into the sea where they float on the tides and have a small but finite chance of encountering ...
lessonae, the population of which decreases. The decrease in the P. lessonae population has, as a consequence, a decrease in produced L gametes, which, in turn, results in a higher production of P. ridibundus. Thus the population of P. ridibundus females grows and eventually out-competes ...
In this process, abnormal gametes and embryos are produced which, consequently, can die in early embryonic life, as found in cattle carrying robs (1;29) [80,81]. Indeed, a higher frequency of abnormal pairings in the hybrids (both F1 and F2 backcrosses) at meiosis was revealed by ...
