An improved protocol for dilution of cryoprotectants from vitrified human blastocysts.
BACKGROUND The purposes of this study were to compare the survival rate of human blastocysts thawed by two different methods after vitrification using electron microscopic (EM) grids, and to report the successful pregnancies and live births resulting from the transfer of blastocysts that had survived the established thawing method. METHODS The blastocysts produced from three pronuclei zygotes...
متن کاملObstetric outcomes after transfer of vitrified blastocysts.
BACKGROUND It has been claimed that the risks to the child resulting from vitrification as compared with the slow-freezing technique, may be higher owing to the high concentrations of potentially toxic cryoprotectants. We therefore retrospectively compared the obstetric and neonatal outcomes in a cohort of children born after transfer of vitrified blastocysts, fresh blastocysts and slow-frozen ...
متن کاملAn Improved Junction-Based Directional Routing Protocol (IJDRP) for VANETs
Vehicular Ad-Hoc Networks (VANETs) is a novel technology that has recently emerged and due to its swift changing topology and high mobility nature, it has become problematic to design an efficient routing protocol in VANETs’ amongst both moving and stationary units. Also, the existing routing algorithms are not very effective to satisfy all requirements of VANETs. This paper explores the need o...
متن کاملFracture formation in vitrified thin films of cryoprotectants.
As a part of an ongoing effort to study the continuum mechanics effects associated with cryopreservation, the current report focuses on fracture formation in vitrified thin films of cryoprotective agents. The current study combines experimental observations with continuum mechanics analysis. Experimental results have been developed using a new imaging device, termed a "cryomacroscope", which ha...
متن کاملImproved Protocol for Isolation of Genomic DNA from Leaf Tissues of Phyllanthus emblica Gaertn
Modified Cetyltrimethylammonium bromide (CTAB) protocol for DNA isolation was developed from leaf tissuesof Phyllanthus emblica for obtaining high quality genomic DNA. Fresh leaves of three different maturitywere analyzed for yield and quality of DNA. Acidity was determined in three different maturity of leaves viz.tender, intermediate and mature and their influence on DNA qua...
