During embryogenesis, SS1 mRNA was detected during early-stage embryonic development, decreased during subsequent developmental stages then increased gradually from the stage of midgastrula onward. This study provides some basic evidence that SS1 may play a role in growth, development and metabolism in C. nasus, and provides a basis for further study of SS neuropeptide family in C. nasus.

C. mrigala displayed the maximum release of eggs, fertilization and hatching rates at 29 ºC. The maximum number of eggs were observed in 26oC whereas the lowest were obtained in 34oC. 85020.48). However, the temperature exceeding 30ºC not only increased the cell growth but significantly decreased...

... harvested in 11 day old embryonated chicken eggs to propagate the NDV, which was then titrated using haemagglutination inhibition assay for quantification of NDV. Polyclonal antibodies were produced in experimental rabbits followed by titration. These antibodies were then used to detect the presence of NDV. Sixteen samples were found positive (20%), 62 negative (77.5 %) and two unreactive (2.5 %) for NDV. All of the poultry farms around Faisalabad showed posi...

...ource of parthenogenetic embryonic stem cells (pESC) has low level of blastocyst rate and quality. CHIR99021 is a material that can increase the formation and quality of blastocysts in buffalo through inhibition of glycogen synthase kinase 3. The purpose of this study was to increase the blastocyst rate and quality of parthenogenetic embryos as a source of pESC primary colonies. Fertilized embryo

Therefore, cumulus cells and their secretion, follicular fluid, effect on oocyte maturation and developmental potential of the resulting embryos in vivo and in vitro. Because of the importance of cumulus cells on follicular development, this review was made to collect and consoli...

...n specific pathogen free embryonated chicken eggs (SPF-ECEs). The dead embryos showed hemorrhages, congestion and dwarfism. The collected allantoic fluids were examined later by haemagglutination (HA) and haemagglutination inhibition (HAI) test. The allantoic fluids of 5 pooled samples expressed positive using specific Newcastle disease virus (NDV) antiserum. The NDV field isolates were confirmed by reverse transcription pol...

The study subjects were divided into group A (low-level group, n=90) and group B (high-level group, n=110) according to serum AMH levels; and group C (successful group, n= 88) and group D (failure group, n=112) according to whether they completed clinical pregnancy. These groups were used t...

... cancer and normal human embryonic kidney HEK-293 cell lines were studied in response to treatment with different concentrations of UNC0642. Inhibition of G9a expression was observed in a dose-dependent manner in both cell lines with increasing UNC0642 concentrations. A dose-dependent downregulation of gene expression of proliferation marker genes (FGF-1, CCND1, and ENO2) was observed in both cell lines, whereas upregulation of tumor suppressor genes (AMPK&alp...

... for in vivo or in vitro embryo production. Oocyte maturation appears to be a simple step, but it is a very complex process. Maturation of oocytes include several changes at the cytoplasmic and nuclear levels that makes the oocytes able to undergo fertilization, pre-implantation and post-implantation embryo development. Oocyte meiotic maturation in vivo starts after LH hormone surge whereas it starts in vitro upon release of...

The changes were affected by in vivo and in vitro molecules and factors of the organisms and the surrounding conditions, respectively. Because of the importance of follicular changes during growth and development stages, which reflected in the developmental competence of oocytes, an att...
