the purpose of this study is to investigate the relationships between teachers’ immediacy behaviors and iranian students’ willingness to talk in english classes. analysis of the results from willingness to talk scale represents a relatively high level of willingness to talk in english classrooms among iranian language learners. the total mean score of students’ willingness to talk was 66.3 ou...
In coffee, bioreactors are the most promising way for scaling-up micropropagation processes, particularly somatic embryogenesis. The availability of an efficient somatic embryogenesis process would allow the rapid mass production of heterozygous materials such as selected Coffea canephora clones and F1 Arabica hybrid varieties. For the last fifteen years, bioreactors (mechanically or pneumatica...
introduction: it is now generally accepted that vero cells provide beneficial effects on improving embryo quality in many animal species. the aim of this research was to determine the effect of vero cell co-culture on the development of vitrified 8-cell mouse embryos. material and methods: eight- cell mouse embryos were provided from superovulated female nmri mice and divided into treatment cas...
Depletion of podocytes, common to glomerular diseases in general, plays a role in the pathogenesis of glomerulosclerosis. Whether podocyte injury in adulthood can be repaired has not been established. Here, we demonstrate that in the adult human kidney, CD133+CD24+ cells consist of a hierarchical population of progenitors that are arranged in a precise sequence within Bowman's capsule and exhib...
Abstract Introduction We present a case of 49-year-old patient who initially presented in May 2020 with an open pilon fracture. Managed initial debridement, fixation, and flap - subsequently underwent circular frame application for failure requiring transport to fusion developed beta-haemolytic streptococcus A within the site proximal corticotomy. Method systematic review literature was conduct...
abstract background: determination of transgenic embryos from non transgenic embryos sibling is an important step in producing homozygous transgenic mice. these steps need by pcr or southern blotting followed extraction of dna, but both techniques require skill and consume time. objective: the aim of this study was simulation of high accuracy method using novel enhanced green fluorescent protei...
One of the most exciting developments in the biological sciences in the past decade has been the discovery and characterization of human embryonic stem cells (ESCs). The interest to transplanters is the potential applications of stem cells in regenerative medicine (RM), which may involve tissue engineering, genetic engineering, and other techniques to repair, replace, or regenerate failing tiss...
We have developed a novel method for microinjection into Xenopus eggs and embryos. Microinjection was performed into eggs or embryos that were placed in wells (ca. 2.5 mm x 2.5 mm x 0.8 mm for each well) at the bottom of a commercially available hybridoma dish, which was filled with 1.5% methylcellulose solution. Eggs or embryos, rotated to a desired orientation in the viscous methylcellulose s...
introduction: the incidence of chromosomal abnormalities was investigated in untransfered embryos reuslted from in vitro fertilization (ivf) or intracytoplasmic sperm injection (icsi) procedures. materials and methods: a total of 238 embryos of varying morphology between the pronucleated stage and 8-cells were analysed. the cytogenetic method of dyban was used for chromosome preparation. embryo...
