Background: Parthenogenesis is the production of an embryo from a female gamete in the absence of any contribution from a male gamete, with or without the eventual development into an adult. In vivo, mammalian parthenogenesis is a rare event. Parthenogenesis can be efficiently induced in vitro with a variety of mechanical, chemical, and electrical stimuli in several species. Hydrostatic pressur...

A 32bp deletion in the chemokine receptor 5 (CCR5) gene (CMKBR5) was shown to be linked to HIV resistance. Bone marrow transplantation from the homozygous CCR5-del32 donor to a CDC Stage 2 HIV-positive recipient was demonstrated to confer a HIV resistance, resulting in discontinuation of antiretroviral therapy. In search for an unlimited source of CCR5-del32 cells for transplantation purposes, ...

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...

In this regard, work a number local international scientists devoted to mulberry silkworm on basis leading traits. effectiveness artificial parthenogenesis m...

the effect of mechanical activation on structural changes and kinetics of carbothermic reduction of hematite with graphite was studied in this research. hematite powder mixture with graphite (with stoichiometry ratio c/o=1) was milled for the time periods of zero to 50 hours, and the structural changes were studied using x ray diffraction (xrd). the effect of mechanical activation on the kineti...

objectives: major depression and anxiety disorders are common psychiatric disorders among cancer patients and are associated with psychosocial impairment and decreased quality of life. depressed and anxious cancer patients also experience a more rapid progression of cancer symptoms, increased mortality, more metastasis and pain, and increased medical utilization. although some research has expl...

the canola drying process was investigated using three laboratory scale dryers connected to a computer which continuously recorded the drying processes of each unit. a completely randomized design (crd) with three replications was used for the statistical analysis. the effect of temperature (40°, 50°, 60°c) and air velocity (1, 2 m/s) on the drying kinetics of a monolayer were studied. the effe...

objective: to evaluate the efficacy of in vitro sperm activation (isa) using non-liquefied versus liquefied asthenozoospermic semen samples for improvement of sperm parameters. materials and methods: fifty six oligoasthenozoospermic (oa) patients (age range: 22-44 years; mean: 32.089 years) were enrolled in this study. oa patients were classified according to type of infertility. also, duration...
