introduction: the purpose of this study was to cultivate bone marrow cells from two different mouse strains (nmri and balb/c) and to examine them in terms of expression of ten surface antigens from primary culture to passage 3. material and methods: 6-8 weeks old either nmri or balb/c mice were sacrificed and their bone marrows were harvested and cultivated .two weeks after culture initiation, ...

Abstract Tools to monitor SARS-CoV-2 transmission and immune responses are needed. We present a neutralization ELISA determine the levels of Ab-mediated virus preclinical model focused immunization strategy. The is strongly correlated with elaborate plaque reduction test (? = 0.9231, p < 0.0001). potency convalescent sera correlates IgG titers against receptor-binding domain (RBD) spike ...

NMRI mice were experimentally infected with Listeria monocytogenes serotypes 1/2b, 3a, 4b, and 4d and Listeria innocua serotype 6b by different means. The course of infection was monitored, using bacteriological and histological methods. The following typical features of experimental infection with the various L. monocytogenes and L. innocua serotypes were observed. (i) On the basis of the mean...

Background Although, both environmental and genetic factors are known as the predispositions to AD development, each of these suggested acts via increasing Al content brain tissue. nanoparticles newer nanomaterials that have been significantly exposed human body. When reaches nanosize, it may display different characteristics from natural Al, its potential influence on body function is an inter...

Papillomaviruses (PVs) induce papillomas, premalignant lesions, and carcinomas in a wide variety of species. PVs are classified first based on their host and tissue tropism and then their genomic diversities. A laboratory mouse papillomavirus, MmuPV1 (formerly MusPV), was horizontally transmitted within an inbred colony of NMRI-Foxn1(nu)/Foxn1nu (nude; T cell deficient) mice of an unknown perio...

introduction: determination of best culture medium for fertilization and development of nmri mice. material and methods: development of fertilized mature oocytes of nmri mice was studied for five days in several culture media (ksom, t6, m16, czb, g1tm ver3 and g2tm ver3) following hormone therapy with pmsg and hcg. results: the rate of fertilization after 24 hours was 97.4% in ksom, 83.5% in t6...
