Morphokinetic analysis of embryo development
Failure to select a viable embryo in a given fertility treatment cycle limits the success rates of current procedures. Fertility clinics rely on a morphological assessment of embryo appearance at a few distinct timepoints during development to pick a viable embryo for transfer. However, embryo development is a very dynamic process and critical stages between observations go unnoticed. This docu...
متن کاملThe CryoLoop facilitates re-vitrification of embryos at four successive stages of development without impairing embryo growth.
BACKGROUND Vitrification has been shown to be an effective method of cryopreservation, but little is known about re-vitrification of embryos. This study investigated the effect of re-vitrification on mouse embryo preimplantation development and viability post-transfer. METHODS Mouse embryos at the 1-cell stage were vitrified using the CryoLoop technique. Embryos were warmed and then re-vitrif...
متن کاملEarly postresuscitation hypotension is associated with increased mortality following pediatric cardiac arrest.
OBJECTIVE To describe the association of systolic hypotension during the first 6 hours after successful resuscitation from pediatric cardiopulmonary arrest with in-hospital mortality. DESIGN Retrospective cohort study. SETTING Fifteen children's hospitals associated with the Pediatric Emergency Care Applied Research Network. PATIENTS Patients between 1 day and 18 years old who had a cardi...
متن کاملIs Induction of Anomalies in Lymphocytes of the Residents of High Background Radiation Areas Associated with Increased Cancer Risk?
Man has been exposed to different levels of natural background radiation since the creation of human life. There are inhabited areas around the world with extraordinary levels of natural background radiation. The level of natural radiation in these areas is up to two orders of magnitude higher than other places. Areas such as Yangjiang, China; Guarapari, Brazil; and Kerala, India are among the ...
متن کاملDevelopment of early mouse and rabbit embryos without zona pellucida.
Criteria for assessing embryo vitality of denuded rabbit and mouse embryos in vitro were: volume of the embryo, number of cells and number of metaphase plates after 24 and 48 h in culture. Mouse embryos grew normally, with and without the zona pellucida, but denuded rabbit embryos showed reduced growth (volume and cell number) and failure to implant in synchronized recipients.
