Manipulation of angiogenesis may have a profound effect on female reproductive function, but this has not yet been demonstrated by direct experiment in species with ovulatory cycles similar to those in women. To investigate whether angiogenesis could be inhibited in the primate corpus luteum, and the consequences of such inhibition on luteal function,(More)
In a previous study pituitary-testicular function was shown to be maintained in a New World primate after the administration of an LHRH agonist implant. In the present study the mechanism of action of the same LHRH agonist (buserelin) on pituitary-gonadal function in the marmoset was investigated and a comparison made between the effects of treatment in(More)
Nine ultrasound transducers from six ultrasound scanners were assessed for their utility for preclinical ultrasound imaging. The transducers were: L8-16, L10-22 (Diasus; Dynamic Imaging Ltd., Livingston, UK); L17-5, L15-7io (iU22; Philips, Seattle, WA, USA), HFL38/13-6 (MicroMaxx; Sonosite Inc., Bothell, WA, USA); il3Lv (Vivid 5; GE, Fairfield, CT, USA),(More)
The determination of the efficacy of gonadotrophin-releasing hormone (GnRH) antagonists in blocking the luteinizing hormone (LH) surge and luteal function is important for our understanding of the control of the menstrual cycle and for clinical application. GnRH antagonists have failed to block the LH surge reliably in the non-human primate. The aim of the(More)
Using specific inhibitors established that angiogenesis in the ovarian follicle and corpus luteum is driven by vascular endothelial growth factor. Recently, it has been demonstrated that the Notch ligand, delta-like ligand 4 (Dll4) negatively regulates vascular endothelial growth factor-mediated vessel sprouting and branching. To investigate the role of(More)
(2009). Exploiting flavour preferences of common marmosets to increase palatability of a dry pellet diet. Although commercially available complete diets exist for common marmosets, the animals' consumption of these diets (available in dry pellet form) is typically very low. Increasing consumption of the pellet diet could have positive consequences for the(More)
