Thirty-six 18-week-old nulliparous does were stimulated with a single dose of 25 IU pregnant mare serum gonadotrophin (PMSG). Ovulation was induced 48 h later with 50 IU luteinizing hormone (LH) (18 does) or 50 IU human chorionic gonadotrophin (HCG) (18 does) in order to determine the effects of pure urinary LH and HCG on the quality of oocytes and embryos.(More)
Human zygotes (n = 278) from 96 in-vitro fertilization gonadotrophin-stimulated cycles were photographed in their pronuclear stage (16-18 h post-insemination). Normal morphological fertilization (two pronuclei) was observed in 215 zygotes, 17 showed only one pronucleus, 40 showed three pronuclei and six showed four. Area, perimeter and maximum and minimum(More)
The aims of this study were to test the presence of discrete sperm subpopulations in Florida goat ejaculates using a computer-assisted sperm analysis (CASA) system and to establish the relationship between the distribution of the subpopulations found and individual buck, total motility, and sperm concentration. Clustering methods and discriminant analysis(More)
In Vitro Fertilization (IVF) units need to decrease multiple pregnancies without affecting their overall success rate. In this study we propose a mathematical model to evaluate an embryo’s potential ability to implant in the uterus. Embryos are graded by the embryologist based on the number of blastomeres, evenness of growth and degree of fragmentation.(More)
The risk of multiple pregnancy to maternal-fetal health can be minimized by reducing the number of embryos transferred. New tools for selecting embryos with the highest implantation potential should be developed. The aim of this study was to evaluate the ability of morphological and morphometric variables to predict implantation by analysing images of(More)
Sarcoidosis is a multisystem granulomatous disease that affects multiple organs in adults between 20 and 50 years old. Interferon alpha (IFN-α) is an immunomodulator that has been used in a wide range of diseases, including hepatitis C virus infection, multiple sclerosis, and other types of neoplasias, including leukemia, lymphoma, Kaposi's sarcoma, and(More)
To assess the contribution of hyperammonemia and inflammation to induction of mild cognitive impairment (or MHE). We analyzed the presence of mild cognitive impairment (CI) by using the PHES battery of psychometric tests and measured the levels of ammonia and of the inflammatory cytokines IL-6 and IL-18 in blood of patients with different types of liver or(More)
A total of 40 New Zealand female rabbits which had been given follicular stimulation and artificial insemination received 50 IU of either recombinant human luteinizing hormone (rhLH; n = 20) or human chorionic gonadotrophin (HCG; n = 20) to induce ovulation. In each hormone group, 10 animals were killed 72 h later to study the ovulatory process and the(More)
In 18-week-old nulliparous rabbit does, ovulation was induced with 50 IU of pure urinary luteinizing hormone (LH; LH group), or 50 IU of human chorionic gonadotrophin (HCG; HCG group), in order to determine the effect of these treatments on 17 beta-oestradiol and progesterone concentrations, and on oocyte and embryo quality. Luteinizing follicles, recovered(More)
