Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

Australian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

In vitro embryo production via ovum pick-up (OPU) and intracytoplasmic sperm injection (ICSI) in pure and crossbred Japanese Hokkaido native ponies

The Journal of Reproduction and Development
This study evaluated the viability of in vitro embryo production using ovum pick-up (OPU) and intracytoplasmic sperm injection (ICSI) as breeding techniques for pure and crossbred Hokkaido native ponies (n = 9).

The L108I polymorphism in mouse prion protein drives spontaneous disease and enhances transmission of atypical and classical prion strains

Brain Pathology, EarlyView.
A single amino acid change (L108I) combined with PrP overexpression drives spontaneous atypical prion formation in mice, enabling also efficient propagation of diverse prion strains. This model allows studying how spontaneous prion diseases arise and provides powerful tools for investigating strain emergence, transmission barriers, and mechanisms ...

Pregnancy outcome of “delayed start” GnRH antagonist protocol versus GnRH antagonist protocol in poor responders: A clinical trial study [PDF]

International Journal of Reproductive BioMedicine, 2017
Background: Management of poor-responding patients is still major challenge in assisted reproductive techniques (ART). Delayed-start GnRH antagonist protocol is recommended to these patients, but little is known in this regards.

Analysis of Human Uniparental Embryonic Stem Cells Reveals New Putative Imprinted Loci

Cell Proliferation, EarlyView.
To identify novel imprinted genes, parthenogenetic, androgenetic and biparental human embryonic stem cells and their differentiated neural progenitors were analysed by methylome and transcriptome profiling. This approach uncovered 12 putative novel imprinted genes, including a clustered region on chromosome 19, expanding the current catalogue of ...

Phosphatase PPP1CC Regulates the First Lineage Segregation by GAS5 in Mouse Preimplantation Embryos

Cell Proliferation, EarlyView.
Subcortical GAS5 directs PPP1CC phosphatase spatiotemporal positioning during mouse morula‐blastocyst transition, controlling YAP dephosphorylation to drive first embryonic lineage specification. ABSTRACT The transcriptional effector of the Hippo signalling pathway, YAP, regulates the first lineage specification in mouse preimplantation embryos ...

Ovarian Cryopreservation and Transplantation: a Preserving Fertility Procedure [PDF]

, 2012
Cancer is a major health problem in both developed and developing countries. In women, cancer incidence rates increased every year. Developments in treatment modalities and the ability to detect tumours in the early stages increased their survival rate ...

Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss

Equine Veterinary Journal, EarlyView.
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

Reproductive Curation: Assisted Reproductive Technologies ( ARTs ) and Lesbian Motherhood‐Making

Journal of Marriage and Family, EarlyView.
ABSTRACT Objective This paper introduces reproductive curation, the deliberate coordination of reproductive arrangements, as a theoretical framework for examining how legal, institutional, and interpersonal factors interact with technology in shaping reproductive decision‐making, based on interviews with 32 lesbian mothers and mothers‐to‐be in China ...
