Large offspring syndrome in cattle and sheep

Abstract Bovine and ovine embryos exposed to a variety of unusual environments prior to the blastocyst stage have resulted in the development of unusually large offspring which can also exhibit a number of organ defects. In these animals, the increased incidence of difficult parturition and of fetal and neonatal losses has limited the large-scale use […]

Parthenogenetic activation of marmoset

Abstract Diversity is a term used in a positive sense, in most scenarios. Humans are diverse, populations are diverse and societies are diverse. Choices, recommendations, and decisions vary and that is why product and service providers give significance to product diversification in their strategies. By providing diverse choices, you are meeting the preferences of more […]

AZFb deletions predict the absence of spermatozoa with testicular sperm extraction

Abstract Genetic abnormalities, including partial deletions of the Y-chromosome, are commonly detectable in men with non-obstructive azoospermia (NOA). NOA can be treated using testicular sperm extraction (TESE) with intracytoplasmic sperm injection (ICSI). Tokens are making news now as an innovative method of crowdfunding, especially for the start-ups which start as small, aiming big. Tokens can […]

Evaluation of the ovarian reserve in young low responders

Abstract OBJECTIVE: To assess the ovarian content of selectable (2-5 mm) follicles using three-dimensional ultrasonography in low responders to ovarian stimulation for IVF. DESIGN: Prospective case-control study. SETTING: IVF program at the Instituto Valenciano de Infertilidad. PATIENT(S): Ten low responders < or =35 years of age with normal basal serum FSH and eight control patients […]

Relationship of ovarian stromal volume to serum androgen concentrations

Abstract The aim of this study was to investigate of the relationship of ovarian stromal volume, measured using three-dimensional ultrasound, to serum androgen concentrations in patients with polycystic ovaries. Serum gonadotrophin, oestradiol and androgen concentrations and ovarian volume measurements were obtained in the early follicular phase from 100 women undergoing assisted conception treatment cycles. Group […]

Tissue engineering of a bioartificial renal tubule

Abstract Development of a bioartificial renal tubule with a confluent monolayer of renal epithelial cells supported on a permeable synthetic surface may be the first step to further optimization of renal substitution therapy currently used with hemodialysis or hemofiltration. Madin-Darby canine kidney cells, a permanent renal epithelial cell line, were seeded into the lumen of […]
