Abstract:
... Gonadal steroids hormones indirectly regulate gonadotropin-rleasing hormone (GnRH) secretion. Kisspeptin (Kp) co-expresses steroid receptors and modulates GnRH release. The objective of the study was to characterise the number and proportion of GnRH and Kp immunoreactive cells and their association in the preoptic area (POA) and hypothalamus during different phases of the oestrous cycle in cows. D ...

Abstract:
... Although many efforts have been made to improve the sperm normal penetration ability for in vitro embryo production (IVP), sperm capacitation in bovine remains a bottleneck for in vitro fertilization (IVF). The variable responses of sperm to the different supplements in IVF medium makes the process suboptimal for every bull. Theophylline, a methylxanthine, has recently been reported to enhance and ...

Abstract:
... In vitro embryo production (IVP) in the domestic bitch is important for conservation of endangered canids. Compared with various domestic animals, the development of assisted reproductive technologies (ART) in the dog has lagged behind, mainly due to the low percentage of oocytes that can reach metaphase II (MII) stage after in vitro maturation (IVM). Beneficial effects of l-carnitine (LC) on embr ...

Abstract:
... In vitro maturation (IVM) of oocytes is a critical step in assisted reproductive technologies carried out in species such as cattle and swine, for generating oocytes capable of being fertilized in vitro and providing healthy offspring useful for biomedical and agricultural purposes. Cumulus-oocyte complexes (COC) collected from abattoir ovaries for IVM often respond poorly to gonadotropins, result ...

Abstract:
... In vitro-produced (IVP) bovine embryos have poor cryotolerance due to high lipid content and reactive oxygen species levels that hinder post-thaw survival. We hypothesised that in-straw rehydration of slow-frozen embryos with sucrose and the addition of the antioxidant polydatin and l-ascorbic acid would increase post-thaw survival. The IVP embryos (n = 116) were generated in 7 replicates by aspir ...

Abstract:
... During a commercial horse cloning program, a critical point is the availability and maintenance of suitable recipient mares for a large quantity of embryo transfers. Usually, pregnancy rates and viable births off the breeding season decrease significantly, whereas the rate of in vitro embryo production remains constant. For this reason, an efficient vitrification system allows continuous embryo pr ...

Abstract:
... Gingivitis, the mildest form of periodontitis, is generally considered a consequence of prolonged exposure of the gingiva to periodontal pathogens. On the other hand, several epidemiologic reports have suggested that other etiologic factors such as oral acidification may also increase the susceptibility of the periodontium to destruction. However, the pathologic mechanism underlying the effects of ...

Hypokinesia presents as a significant reduction in both escape response and spontaneous walking. We examined aminergic and peptidergic components of milked venom with HPLC and MALDI-TOF mass spectrometry. ...
