In neurocysticercosis, the nervous tissue surrounding the brain lesion is affected as a consequence of the local immune response induced by a Taenia solium metacestode. In this study, a histological and immunohistochemical analysis of five brain specimens from patients with neurocysticercosis revealed a proinflammatory activity reflected by an apparently(More)
A sperm cryopreservation protocol requiring dimethylacetamide (DMA, 6%) as a cryoprotectant was optimized via assays involving different prefreezing equilibration times (1, 10, 30, 60, and 120 min at 5°C) and different freezing rates achieved by the following: 1) using nitrogen vapor to reduce the temperature from 5°C to -85°C at 10°C/min (slow freezing(More)
Postcopulatory sexual selection through sperm competition may be an important evolutionary force affecting many reproductive traits, including sperm morphometrics. Environmental factors such as pollutants, pesticides, and climate change may affect different sperm traits, and thus reproduction, in sensitive bird species. Many sperm-handling processes used in(More)
This paper reports the first successful artificial insemination (AI) of red-legged partridges (Alectoris rufa), the fertility rate achieved, and the length of time sperm cells can survive inside the oviduct (i.e., the post-AI fertile period). Semen from 20 mature males was collected by massage and pooled for use in single intravaginal inseminations (20 μL(More)
