The objective of this study was to elucidate ovarian follicular dynamics in swamp buffalo cows (Bubalus bulalis) following a protocol for estrus synchronization during hot as low breeding season (March to June) and cool as high breeding season (November to February). Nine pluriparous buffalo cows received a progesterone ear implant for 10 days together with the administration of a luteolytic do...

BACKGROUND Studies of lizards have shown that offspring size cannot be altered by manipulating clutch size in species with a high clutch frequency. This raises a question of whether clutch frequency has a key role in influencing the offspring size-number trade-off in lizards. METHODOLOGY/PRINCIPAL FINDINGS To test the hypothesis that females reproducing more frequently are less likely to trad...

Neurotrophins are growth factors that are known to have a role in promoting cell survival and differentiation. The focus of the current study is to examine the role of neurotrophins in regulating ovarian primordial follicle development. Ovaries from 4-day old rats were placed into organ culture and cultured for 10 days in the absence or presence of neurotrophin-3 (NT3), brain-derived neurotroph...

The pilosebaceous unit is a complex structure that undergoes a specific growth cycle and comprises a few important drug targeting sites. For example, drugs can be targeted to the bulge region with stem cells or to the sebaceous glands. Interest in pilosebaceous units is directed towards their utilization as reservoirs for localized therapy and also as a transport pathway for systemic drug deliv...

In the current review the main fundamental biological differences in reproductive function between Bos taurus and Bos indicus cattle are discussed. Breed differences regarding puberty, estrous cycle patterns, estrous behavior, acquisition of ovulatory capacity, ovarian structures and reproductive hormones are presented. The main physiological differences that Bos indicus cattle present relative...

The aim of this study was to establish radiographic criteria for early diagnosis of cystic changes in dental follicles associated with impacted third molars and thereby prevent the development of a pathological cyst and its associated complications. This case control study was performed involving 20 cases of impacted third molars with follicle size measuring <2.5mm and 4 controls with follicle ...
