Evidence suggests that transcranial direct current stimulation (tDCS) modulates conditioned fear memories and has effects on cognitive flexibility via the dopaminergic system. This study examines whether modulation of scopolamine-induced memory deficit by anodal tDCS could be mediated The male NMRI mice received scopolamine, 30 min before conditioning, showed impaired contextual retention. Mice...
Outbred suckling mice (NMRI strain) were used as hosts. They were initially inoculated with oocysts of human origin, and subsequently with parasites recovered from the mouse ileal mucosa. Cryptosporidia were counted in an aliquot of whole-ileum homogenate. Parasite load was expressed as cryptosporidia per centimeter of ileum. Serial passage of C. parvum in NMRI mouse litters led to a gradual am...
Treatment of NMRI mice with isoniazid (INH; 25 mg/kg) intraperitoneally induced significant protection when it was injected before or after a lethal intravenous challenge with endotoxin. The INH preparation used was not contaminated with endotoxin. Tumor necrosis factor (TNF) was not elevated in sera from NMRI mice 2 h after the injection of INH. INH did not influence TNF synthesis or release d...
Objective(s):Recent evidence have proposed that Tretinoin produced in the gut preferentially promote differentiation of FoxP3+Treg cells but inhibits Th17 lymphocytes, and this may be the main immunomdulatory mechanism of Tretinoin in vivo. This study was done to investigate the effects of Tretinoin in outbred white mice after challenge with sheep red blood cells (SRBC). Materials and Methods:...
Background: The quality and quantity of the diet has undeniable effects on the reproduction of organisms. We examined the effects of two diets (with and without mineral supplementation-Vitamins) on super-ovulation in two strains of mice (B6D2F1 and NMRI) in Royan Institute, Tehran. Materials and Methods: For this purpose, 40 female mice (21 days) from each strain were divided into four experime...
Background: Spermatogenesis associated 19 (Spata19) was introduced as a testis-specific gene that probably involved in spermatogenesis cell apoptosis. Therefore, this study aimed to investigate the effect of Spata19 inactivation on sperm count. Materials and Methods: We generated global knockout mice by CRISPR/Cas9 nickase technology. Disability validated three levels DNA, RNA, protein using PC...
We describe a localized proton magnetic resonance spectroscopy ((1)H-MRS) method for in vivo measurement of lipid composition in very small voxels (1.5 mm x 1.5 mm x 1.5 mm) in adipose tissue in mice. The method uses localized point-resolved spectroscopy to collect (1)H spectra from voxels in intra-abdominal white adipose tissue (WAT) and brown adipose tissue (BAT) deposits. Nonlinear least-squ...
most of the systematic studies used in the development of human embryo culture media have been done first on mouse embryos. the general use of nmri outbred mice is a model for toxicology, teratology and pharmacology. nmri mouse embryo exhibit the two-cell block in vitro. the objective of this study was to evaluate and compare the effects of four kinds of culture media on the development of zygo...
