After getting pregnant by in vitro fertilization (IVF), pregnancy loss is one factor that prevents the baby from being born. An estimated 80% of pregnancy loss occurs in the first trimester, which is higher than in the natural pregnancy. The reason is said to be that the age of women receiving fertility treatment is often higher, leading to ovarian reserve, and decreased oocyte quantity and quality.

In this research, we have compared the developing embryos in vitro capacity of oocytes collected from slaughtered cows and ones collected by Ovum Pick Up (OPU) from living cows. As the result showed that, by OPU technology, we have collected many high quality oocytes, that increased the developing capacity of the oocytes grown in vitro. Therefore, that increased the percentage fertilization and the developing capacity of the embryos grown in vitro.

The results showed that penetration and normal fertilization rates in both TCM-199 groups are both higher than that of NCSU-37 group. Moreover, the cleavage and blastocyst rates, and cell numbers of blastocysts which is a criterion for embryo quality were all higher in TCM-199 groups, especially in the group supplemented with pFF. It might be concluded that TCM-199 media supplemented with either pFF or FBS are suitable for effective in vitro maturation of Landrace porcine oocytes collected in Vietnam.

Maternal transcripts are accumulated in the oocyte during oogenesis to provide for protein synthesis from oocyte maturation through early embryonic development, when nuclear transcription is silenced.

Transcription is arrested in the late stage oocyte and therefore the maternal transcriptome stored in the oocyte provides nearly all the mRNA required for oocyte maturation, fertilization, and early cleavage of the embryo.

In this research, we have compared the growing capacity after thawing out frozen embryos which had different qualities and were formed from different source of oocytes. The results show that, the embryos which have standard forms, embryonic cells connected closely, without or few seperated cells or crushed pieces outside would have high growing capacity of frozen embryos after thawing out.

Sperm-mediated gene transfer (SMGT) is a transgenic technique involves transfer of the genes based on the spermability to bind spontaneously and internalize the exogenous DNA, and transport it into an oocyte during fertilization to produce genetically modified animals. Spermatozoa play a major role in transgenesis in virtually all species. Their ability to take up exogenous DNA molecules to transmit novel genetic information to the offspring after fertilization can be exploited.

The efficiency of Oocyte collection by aspiration method was assessed. A sum of 980 caprine ovaries were collected from local abattoir and used for the present study. Out of these ovaries a total of 3243 oocytes were collected. Out of which 2254 culturable oocytes were selected under stereomicroscope. The total number of oocytes and culturable oocytes recovered per ovary were 3.2 and 2.4 respectively 30%of the total population comprised fully and partially denuded oocytes which were not used.

A study was taken up to know the effect of corpus luteum (CL) on the oocytes retrieval, quality in buffalo ovaries. Ovaries were collected from apparent healthy slaughtered buffalo during breeding season and categorized based on the presence (or) absence of CL. The cumulus oocyte complexes (COCs) were aspirated aseptically from the follicles of >6 mm diameter present on the surface of the ovary by using 18 G needle attached to 5 ml disposable syringe containing 2 ml of collection media.

Serum gonadotropin @50 and 100IU/ml, estrodiol-17β @0.5 and 1μg/ml, EBS @5 and 10% and BFF @5 and 10% supplementation Iis done on cleavage rate of buffalo oocytes for the comparison of efficacy of hormones. Ovaries were collected from buffaloes slaughtered at local abattoir. Oocytes were aspirated and good and excellent quality oocytes were matured in basic maturation media TCM199 supplementing above mentioned supplements separately.

To determine if the presence of reproductive messages is a long term, enduring feature of song lyrics, the fourth study was based on a content analysis of the lyrics contained in a sample of representative art songs and opera aria dating back as far as 1597. Arias are usually a melodic segment set within the context of a larger composition called an opera. Though arias are often performed independent of the full opera, they derive much of their meaning from the framework of the surrounding composition. In contrast, Art songs are smaller scale compositions that...

The prominence of private health insurance has been buttressed by government interventions directed at PHI markets in several OECD health systems, although the effectiveness of policies aimed at increasing market size and fostering outcome quality has differed widely. Australia, Ireland, the Netherlands, Germany, Switzerland and the United States have promoted and maintained a large and viable private health insurance market because policy makers have concluded that mixed public-private coverage systems can better deliver desired health policy and social outcomes.
