Background: Artificial oocyte activation (AOA) has important implications in assisted reproductive technique (ART) with particular importance in somatic cell nuclear transfer (SCNT). Parthenogenesis activation using zona- free oocytes offers an alternative model that could be applied to develop protocols for the activation of reconstructed embryos for cloning. Materials and Methods: To establis...

Low and/or total failed fertilization following ICSI is a disappointing effect that some couples may face during their treatment which may have severe social and economic consequences for these infertile couples. This phenomenon has been mainly attributed to failed oocyte activation post ICSI. Researchers have regarded this failure due to the absence or deficiency of sperm associated to oocyte ...

OBJECTIVE The goal of this study was to compare the muscle activation patterns in various major leg muscles during treadmill ambulation with those exhibited during robotic-assisted walking. BACKGROUND Robotic devices are now being integrated into neurorehabilitation programs with promising results. The influence of these devices on altering naturally occurring muscle activation patterns utili...

Interfacial shear-driven or shear-assisted chemical reactions play an important role in many engineering processes, including between lubricant additives and the surfaces of mechanical components fabrication surface topographic features. Mechanistic studies often employ a mechanically assisted thermal activation model from which so-called volume can be defined. Activation is because it quantifi...

in this study, the recycling possibility of residual oil fly ash (rofa) towards preparing activated carbon and its application in environmental remediation through adsorbing cu (ii) and pb (ii) ions from aqueous solutions were investigated. activated carbons were prepared using two different physical activation methods such as under steam flow at 950 0c, and combined steam and co2 flow at 850 0...

Preparation of bentonite clay–coconut husk composite (BECH) via microwave-assisted carbonization, the activation BECH with HCl (BECH-H) and KOH (BECH-K) adsorption ciprofloxacin, tetracycline, bisphenol A from aqueous solutions.

Background: Failed fertilization after intracytoplasmic sperm injection (ICSI) can be due to a reduced oocyte-activation capacity caused by reduced concentrations and abnormal localization of the oocyte-activation factor phospholipase C (PLC) zeta. Patients with this condition can be helped to conceive by artificial activation of oocytes after ICSI with calcium ionophore (assisted oocyte activa...
