Incidence of monozygotic twins in blastocyst and cleavage stage assisted reproductive technology cycles.
OBJECTIVE To study the incidence of monozygotic twins (MZT) in blastocyst and cleavage stage ET. DESIGN Retrospective review. PATIENT(S) Four hundred ninety-six women undergoing IVF/intracytoplasmic sperm injection cycles at a private assisted reproductive technology (ART) center. INTERVENTION(S) Patients undergoing ART were divided according to the stage of ET into blastocyst transfer (B...
متن کاملMonozygotic Triplets and Dizygotic Twins following Transfer of Three Poor-Quality Cleavage Stage Embryos
Background. Assisted reproductive technology has been linked to the increased incidence of monozygotic twinning. It is of clinical importance due to the increased risk of complications in multiple pregnancies in general and in monozygotic twins in particular. Case. A 29-year-old female, nulligravida underwent her first IVF cycle. Three poor-quality cleavage stage embryos were transferred result...
متن کاملGroup selection management in conifer forests: relationships between opening size and tree growth
Replicated circular openings ranging in size from 0.1 to 1 ha were cleared in 1996 at Blodgett Forest Research Station, California, and planted with seedlings of six native species. After 5 years of postharvest growth, heights were measured and analyzed according to species, opening size, and location within opening. The sequence of mean height from tallest to shortest, according to species, wa...

Glutathione/ glutathione disulfide and ascorbic acid /dehydroascorbateare two major redox pairs that control the redox-state in a developing seed.Recently these redox compounds have been shown to exert strong positive effectson embryo development in several plants including white spruce. A picture isemerging that early-stage embryo development occurs best in the presence of a<lb...
متن کاملPredicting tryptic cleavage from proteomics data using decision tree ensembles.
Trypsin is the workhorse protease in mass spectrometry-based proteomics experiments and is used to digest proteins into more readily analyzable peptides. To identify these peptides after mass spectrometric analysis, the actual digestion has to be mimicked as faithfully as possible in silico. In this paper we introduce CP-DT (Cleavage Prediction with Decision Trees), an algorithm based on a deci...
