The provision of a low dose (100 ova) in some of the experiments produced mice with lower burdens in the brain. Ocular haemorrhage was observed only in the infected mice, more frequently in those receiving a higher dose of ova. The level of infection in the brain was lower in mice receiving a multiple as opposed to an equivalent single dose of ova. Ova with two distinct pronuclei and the second polar body were considered normally fertilised. In women, eggs (sometimes called ova) are made in the ovaries. Any ova with broken or cracked zonae were discarded before and after heat treatment. In our present study we were unable to make the zonae of salt-stored human ova penetrable to spermatozoa. In all cases, the cure rate (proportion of subjects treated in whom disappearance of ova and\\or parasites was observed after treatment) has been tabulated. A recipient received 22 ova and delivered three live piglets. The measurement was performed using three ova for each lectin. The remaining ova (27.8%) were not able to develop beyond the pronuclear stage. Ten to twelve hours after insemination, the number of pronuclei was counted under a dissection microscope to determine the ploidy of fertilised ova. There is also the process of recombination of two fertilized ova into one. They point to the alarming consequences of ova-enthusiastic extrapolation across species. Fertilizable life of golden hamster ova and their morphological changes at the time of losing fertilizability. Effect of age of the donor and recipient on the development of the transferred golden hamster ova. The fertilizable life of ova and their morphology following delayed insemination in mature and immature mice. Inhibition of in vitro fertilisation of rabbit ova by trypsin inhibitors. If such a crossover did take place, half the ova will be homozygous and half will be heterozygous. In particular, as women get older until the age of about 38, the probability of their releasing two ova in a given cycle increases. Had the ova been collected from a random sample, small sample size would still preclude the use of this estimate in our work. The third trial (n = 3 replicate experiments) included 0 and 22 h in vitro matured oocytes as well as fertilised ova and 2-cell embryos. Preliminary estimates of the permeability of mouse ova and early embryos to glycerol. Relationship between heparin binding characteristics and ability of human spermatozoa to penetrate hamster ova. The town is situated in the north of the province on a 1100-1150 m. high plain (ova) which is entirely surrounded by mountains. Recombination rates were estimated by the ratio between the inferred heterozygous and the total number of ova. When zygosities were determined, frequencies of triplets derived from one, two and three ova individually failed to show any secular trend of significance. The level of infection in the brain was lower in the mice receiving a multiple as opposed to an equivalent single dose of ova. Inhibition of in vitro fertilization of rabbit ova by trypsin inhibitors. Ultimately, 65.5% of monospermic ova reached morula to blastocyst stages. Within 30 h of fertilisation, 182 ova (93.8%) cleaved to the 2-cell stage, and subsequently 163 ova (84.0%) developed beyond the 2-cell stage. Fertilised ova at the pronuclear stage were collected from the oviducts of naturally mated females 10-12 h after the estimated time of ovulation. In this study human mitochondria were transferred by microinjection into fertilised murine ova which were further cultured to the blastocyst stage. The proportions of ova that cleaved are indicated above each bar. Fertilized and unfertilized ova are transported at different rates by the hamster oviduct. In vitro fertilization of tubal rabbit ova partially or totally denuded of follicular cells. Shortly after the adult moults she releases ova into her ovaries. Within strains, fewer larvae were recovered after a trickle dose of 1000 ova compared to a single dose of 1000 ova. The authors conclude that the method described is both convenient and adaptable for a scanning electron microscope study of animal parasite ova. If we knew how old the ova were, we could judge the accuracy of the [criteria]. In contrast, the number of particles in ova at the 4cell stage was 1532 + 205, which was a significant increase compared with the unfertilised oocyte. An oviductal fluid glycoprotein associated with ovulated mouse ova and early embryos. The role of the cumulus-corona cells surrounding in vitro human oocytes and polypronuclear ova: an ultrastructural study. Although 129 (66.5%) of monospermic ova developed into morula stage, blastocyst formation was observed in only 17 embryos. The pipette was moved to a drop containing ova. Successful coculture of 1-4 cell stage cattle ova to the morula or blastocyst stage. Therefore, they were regarded as parthenogenetic ova activated by contact with the head of the zona-penetrating spermatozoon. The remaining ova were also inseminated with acrosome-reacted spermatozoa after removal of their cumulus cells by treatment with 0.1% (w/v) hyaluronidase. No more than 15 ova were inseminated in a single drop. The zona reaction of hamster and mouse eggs: term offspring from in v/fro-fertilized ova. The proportions of ova are indicated in the bar graph. The prevalence data we used were based on a standard single stool ova and parasite examination, which has an average test sensitivity value of approximately 25 % [17, 18]. The antifertility activity of the antibodies to the synthetic peptide fragments was further evaluated by determining their effects on the in vitro fertilisation of murine ova. The fertilization of rabbit ova in relation to ovulation. In vitro fertilization, culture and transfer of rabbit ova. Fertilization in vitro and development of mouse ova. Apoptosis in the degeneration process of unfertilized mouse ova. Thus, at any one time the adult has offspring at three stages of development : unreleased ova, developing eggs in the ovaries, and developing juveniles in the brood chamber. Slides, prepared by resuspending a small volume of faeces in normal saline and iodine, were examined and ova and parasites identified on the basis of morphology and size. The microclimatic requirements for embryonation and survival of nematode ova and larvae, principally in terms of temperature and moisture, have been extensively studied under laboratory conditions [20 -24]. Eventually, 132 ova (62.3%) were successfully karyotyped. Fertilization of mouse ova in vitro: an electron microscopic study. Contrast in levels of metabolic enzymes in human and mouse ova. Mitochondrial transfer into mouse ova by microinjection. By better defining culture conditions that result in viable ova, inter- and intracellular mechanisms responsible for initiating and completing successful oocyte maturation can be more readily examined. More efficient production of mature ova would improve the outcome of assisted reproduction in humans and endangered species as well as benefiting transgenic biotechnology and basic research. The use of zona-free animal ova as a test system for the assessment of the fertilizing capacity of human spermatozoa. Developmental changes in the respiratory activity of rabbit ova. Immunization of rats with cumulus-free mouse ova: induction of infertility and antibody titres. Successful culture of in vitro of sheep and cattle ova. The adult female produces thousands of ova per day, which are passed out of the body in faeces and develop into filariform larvae in warm and moist soil conditions. First, the decline in p(m) may be associated with the ovum itself, the initial and final values of p(m) being the same for all ova. The destruction of helminth ova and larvae in a slurry treatment process. The value of formol-ether concentration of faecal cysts and ova. In vitro fertilization of golden hamster ova.
