the goal of this study was to investigate the common clinical chemistry and distribution of xanthine oxidase (xo) in selected tissues of a mouse model of menopause. twenty four nmri female mice were divided into three groups: normal control (nc), and ovariectomized (ovx) groups and an estrogen-treated ovariectomized (ovx+e) group which received subcutaneous injection of estradiol benzoate (2 mg...

mice are ideal models for icsi experiments because of the ease of culturing eggs/embryos in vitro and the availability of ample genetic information. unfortunately, it has been extremely difficult. in this study we improved the mouse icsi method by using a new holding pipette that was made of two pipettes such that one pipette was pulled and heat merged into the other one. the outer pipette had ...

neospora caninum (n. caninum) is an apicomplexan parasite and causes abortion and congenital neosporosis in cattle worldwide. in this study, we evaluate the virulence of a n. caninum isolate on mouse strain c57bl/6. six groups of five mice c57bl/6 were intraperitoneally inoculated with 1 × l07, 1.5 × l07, 2 × l07, 3 × l07 and 4 × l07 tachyzoites and a control inoculum of dmem, respectively. cli...

objective: this study presents an efficient, cost-effective method to improve proliferation and colonization of spermatogonial stem cells (sscs) in vitro. methods: isolated sscs from neonate mice were cultured in dmem culture medium with 10% fetal bovine serum (fbs). in the first phase of the study, the temperature was controlled by low intensity pulsed ultrasound stimulation (lipus) of the pla...

Background: Sports, hypothermia and hyperthermia as some stressors inhibit male reproductive functions and are associated with subfertility or infertility. We investigated whether water temperature and chronic swimming are effective on mouse sperm parameters. Materials and Methods: Adult male mouse(N=35) were randomly divided into 7 groups: 1-controls 2-cold water (100C) with swimming 3- cold w...

Surfaces with hydrophilic and antimicrobial properties are very attractive for cardiovascular device-associated applications. The aim of this study was to prepare coat a polymer containing functional group capable forming triazole functionality onto the surface polyurethane (PU). modified surfaces were assessed cell adhesion, bacterial adhesion viability. Mouse fibroblast cells (NIH-3T3) three ...

Since the mouse offers an easily manipulated experimental animal model for the study of the immunopathogenesis of pneumonia caused by the opportunist Pneumocystis carinii, we cloned and characterized cDNAs encoding an abundant, immunogenic surface antigen termed glycoprotein A (gpA) from mouse P. carinii. A cDNA library was constructed in bacteriophage lambda gt11 from P. carinii-infected mouse...

This study utilized an external logger system for onsite measurements of computer activities of two professional groups-twelve university administrators and twelve computer-aided design (CAD) draftsmen. Computer use of each participant was recorded for 10 consecutive days-an average of 7.9+/-1.8 workdays and 7.8+/-1.5 workdays for administrators and draftsmen, respectively. Quantitative paramet...
