Histological Study of Ostrich Skin after Biopsy
Objective- To investigate histological structure of Ostrich skin was done. Ostrich leathers are of exotic leather types, which are in increasing demand due to their outstanding natural gain patterns formed by large feather follicles on the leather surface. Animals-Ten mature ostriches were selected from ostrich breeding center in Jupar, Kerman, Iran, all of which were in good shape and healthy ...
متن کاملPerformance of miniature pgs after partial body irradiation.
Thirty-two miniature pigs were trained by shock avoidance conditioning to traverse a two-chambered shuttlebox. Eight unshielded pigs (whole-body exposed) received midline tissue doses (MTD) of about 13, 000 rads of pulsed, mixed gammaneutron radlations to the head and trunk. Eight head-shielded and eight trunkshielded pigs received doses to the unsh!eldcd part of the body that were equivalent t...
متن کاملEffects of blastomere biopsy on post-natal growth and behavior in mice.
STUDY QUESTION Does blastomere biopsy (BB) of preimplantation embryos induce long-term effects on their growth and post-natal behavior? SUMMARY ANSWER BB induces long-term effects on body weight and behavior in male mice. WHAT IS KNOWN ALREADY BB is an essential technique for performing preimplantation genetic diagnosis (PGD), a screening test that can detect genetic abnormalities of embryo...
متن کاملWhat next for preimplantation genetic screening (PGS)? Experience with blastocyst biopsy and testing for aneuploidy.
Blastocysts more commonly have a normal karyotype than cleavage-stage embryos do. Moreover, blastocysts have also made a metabolic transition from catabolism and recycling of the oocyte's reserves and resources, processes that fuel the first 3 days of cleavage. Although not all blastocysts are karyotypically equal, it is still to be determined to what extent a mosaic karyotype might be a normal...
متن کاملBiopsy of Human Morula-Stage Embryos: Outcome of 215 IVF/ICSI Cycles with PGS
Preimplantation genetic diagnosis (PGD) is commonly performed on biopsies from 6-8-cell-stage embryos or blastocyst trophectoderm obtained on day 3 or 5, respectively. Day 4 human embryos at the morula stage were successfully biopsied. Biopsy was performed on 709 morulae from 215 ICSI cycles with preimplantation genetic screening (PGS), and 3-7 cells were obtained from each embryo. The most com...
