The xenotropic and polytropic mouse leukemia viruses (X-MLVs and P-MLVs, respectively) have different host ranges but use the same functionally polymorphic receptor, XPR1, for entry. Endogenous retroviruses (ERVs) of these 2 gammaretrovirus subtypes are largely segregated in different house mouse subspecies, but both MLV types are found in the classical strains of laboratory mice, which are gen...

Background & Aims: Teucrium polium (TP) is amongst the commonly used remedies in traditional medicine. Some reports have claimed hepatotoxicity of TP but other reports have not supported it. This study was designed to evaluate the probable hepatotoxicity of TP. Methods: Petroleum ether fraction of TP was dissolved in DMSO and the final concentration was adjusted by diluting in physiologic salin...

The laboratory mouse serves as an important model system for studying gene, brain and behavioural interactions. Powerful methods of gene targeting have helped to decipher gene-function associations in human diseases. Yet, the laboratory mouse, obtained after decades of human-driven artificial selection, inbreeding, and adaptation to captivity, is of limited use for the study of fitness-driven b...

nowadays gamete and embryo freezing is an appropriate approach for preserving of genetic traits in laboratory animals, rare and endangered species. frozen cells are suitable replace for actively breeding animals colony. the aim of this study was to perserve laboratory mouse embryo, using vitrification method and comparing effect of two cryoprotectants, glycerol-sucrose(gs) and ethylene glycol-f...

background: caffeine increases the camp production that stimulates spermatozoa movement. caffeine is also used for induction of in vitro acrosome reaction in mammalian spermatozoa, an important step in achieving fertilization. objective: the aim of this study was to assess the effect of caffeine on sperm's motility, vitality and laboratory fertilization rates in mouse in two t6 and m16 media. m...

This study was conducted to optimize a fusion protein vaccine for translational development as against the human tropical parasitic infection, lymphatic filariasis (LF). The candidate, His-tagged r Bm HAXT developed previously in our laboratory and tested various animal models including mouse, gerbils Rhesus macaque where it exhibited significant levels of vaccine-induced protection. However, c...
