Prior to ICSI the cumulus-oophorous-complex of the oocyte is commonly remove with impure animal-derived hyaluronidase of low strength. The lower strength of the enzyme, the high concentration of impurities and the necessity of extensive time-dependent mechanical denudation damages of the oocytes, increases the risk of lysing the oocytes and the transfer of animal-derived pathogens. All this can...

The variation in climatic variables like temperature, humidity and radiations were recognized as the potential hazards in the growth and production of all domestic livestock species. Thermal environment is a major factor that can negatively affect both production and reproduction in dairy animals, especially in animals of high genetic merit. Among the stressors, heat stress has been of major co...

Coping with water shortages without compromising tuber yield is a majorchallenge for potato (Solanum tuberosum L.) production in northern China. In thisstudy, we used three potato cultivars with different sensitivities to drought toevaluate the effect of long-term drought stress on morphological and physiologicalcharacteristics under field conditions during three growing seasons (2009-2011).Our...

The unique collaboration of the two major physiological societies, The Physiological Society and the American Physiological Society, in their first joint publishing venture, highlights that something of major importance is happening. That event is the launch of this journal, Physiological Reports. This online-only journal will be the flagship open access vehicle for the two societies, adding a ...
