In 2005, the European Society for Human Reproduction and Embryology (ESHRE) Preimplantation Genetic Diagnosis (PGD) Consortium published a set of Guidelines for Best Practice to give information, support and guidance to potential, existing and fledgling PGD programmes (Thornhill AR, De Die-Smulders CE, Geraedts JP, Harper JC, Harton GL, Lavery SA, Moutou C, Robinson MD, Schmutzler AG, Scriven P...

Preimplantation genetic diagnosis is a preventive approach for identifying genetic abnormalities in early stages of reproduction. We used preimplantation genetic aneuploidy screening in 230 cycles of patients with indications of advanced maternal age, recurrent implantation failure, recurrent spontaneous abortions, or severe male factor. Biopsied blastomeres from embryos with six to eight ...

Ectopic pregnancy (EP) is defined as a implanted outside of the endometrial cavity and one leading causes maternal morbidity mortality during first trimester. There are several risk factors ectopic have been described especially following ART. However, prevalence varied slightly higher in pregnancies Several mechanisms EP Serial serum beta hCG pelvic sonographic screening facilitates early diag...

In vitro plant tissue culture and biotechnology used to assist support the development of breeding when classical methods propagation must be accelerated or it was necessary overcome barriers inaccessible by approaches. asparagus, improve multiple tasks, a high number in have been used, such as regeneration through organogenesis, embryogenesis, manipulation ploidy, protoplast isolation, genetic...

Для выявления генетических патологий плода женщин на I триместре беременности проанализированы 456 результатов скрининга биохимических и ультразвуковых маркеров анеуплоидии, проведённого базе клиники ООО «Медикал Геномикс» (г. Тверь). Самым распространённым заболеванием у обследованных являлся синдром Дауна (89% от всех выявленных возможных аномалий развития эмбриона). Биохимические маркеры скр...

Thalidomide, a drug known for its teratogenic side-effects, is used successfully to treat a variety of clinical conditions including leprosy and multiple myeloma. Intense efforts are underway to synthesize and identify safer, clinically relevant analogs. Here, we conduct a preliminary in vivo screen of a library of new thalidomide analogs to determine which agents demonstrate activity, and desc...

As numerical and structural defects in chromosomes are an inevitable consequence of IVF, Pre-implantation genetic diagnosis and screening (PGD/PGS) methods are used for detecting abnormalities in embryos before implantation to the uterus to increase the successful rate of IVF. Pre-implantation genetic diagnosis and screening approaches can be achieved by different techniques such as NGS, CGH an...

BACKGROUND Ischemia is a pathophysiological condition due to blockade in blood supply to a specific tissue thus damaging the physiological activity of the tissue. Different in vivo models are presently available to study ischemia in heart and other tissues. However, no ex vivo ischemia model has been available to date for routine ischemia research and for faster screening of anti-ischemia drugs...

the society for assisted reproductive technology (sart) method of embryo grading is unique, simple, and widely practiced, and its use has been mandatory for sart membership programs since 2010. developed by sart in 2006, the current embryo grading system categories, “good, fair, and poor,” are limited because they do not describe the best 1-2 embryos in the interest of keeping pace with the shi...
