An Anglican theologian contends that the claim to absolute protection for the human embryo from the moment of conception is a recent one in the Roman Catholic moral tradition. Citing pre-classical, classical, biblical, and post-biblical Roman Catholic sources, Dunstan argues that these traditions attempted to grade the protection provided to the nascent human being according to the stages of i...

Background: Our Background was to evaluate the effect of ovarian endometrioma on ovarian stimulation outcomes in Intra Cytoplasmic Sperm Injection (ICSI). Materials and Methods: In this prospective cohort study, we followed 103 patients underwent ICSI procedures at royan Institute during 10 month. The study group consisted of 46 women who had endometriomawith size more than 1 cm. The control gr...

Recurrent implantation failure (RIF) has many definitions, but usually authors consider RIF, the failure to achieve a pregnancy fallowing 2-6 IVF cycles in which more than 10 high grade embryos were transferred to the uterus. There are a lot of causes for RIF but two main causes of that are related to embryo and endometrium. Chromosomal abnormalities, zona hardening and problems in culture medi...

This study aimed to assess the effects of embryonic developmental stage, quality grade, and fresh or frozen/thawed conditions on pregnancy rate sex ratio live offspring in Hanwoo (<italic>Bos taurus coreanae</italic>) cows. The stage <italic>in vivo</italic>-derived (IVD) transferred embryos were evaluated using standard criteria International Embryo Technology Society. ...

OBJECTIVE The aim of this prospective study was to investigate whether ovarian blood flow is related to embryological parameters and whether it could be a predictor of outcomes of IVF/ICSI. METHODS Eighty infertile women underwent ovarian stimulation with gonadotrophins after a long protocol with GnRH agonists. The ovarian volume (OV), number of follicles (NF) and follicular volume (FV) of al...

Human induced pluripotent stem cells (hiPSCs) are a promising cellular source in cell therapies or regenerative medicine and they allow to address fundamental mechanisms embryo-genesis. However, their culture provide large amounts of high quality remains challenging. Here, using an encapsulation microfluidic device, we observe that hiPSCs self-organize into cysts, which spherical closed epithel...

background: successful embryo transfer (et) technique is a fateful step of all efforts to achieve live births from in vitro produced embryos in assisted reproductive techniques or in knockout, transgenic or cloned animal projects. small reproductive tract of mice and limitation of current techniques may not well satisfy the requirements for mass production of genetically modified mice. genetic ...

i.p.s. hypergroups are canonical hypergroups such that$[forall(a,x),a+xni x]longrightarrow[a+x=x].$i.p.s. hypergroups were investigated in [1], [2], [3], [4] and it was proved thatif the order is less than 9, they are strongly canonical (see [13]). in this paperwe obtain the sequences of fuzzy sets and of join spaces determined (see [8])by all i.p.s. hypergroups of order seven. for the meaning ...
