Mice, similarly to some other rodent species, communicate with specialized sounds in the ultrasonic range called ultrasonic vocalizations (USV). Evaluation of this behavioral activity enables estimation of the social interactions in animal models of autistic spectrum disorders (ASD). Because transgenic mouse models are generated, in most cases, on the mixed 129SV/C57BL6 genetic background, we w...

Introduction: One of the most obvious morphological changes due to aging is the formation of facial wrinkles, which are remarkably visible at middle ages and can have a significant effect on the quality of life of individuals. It is believed that UVB is one of the main causes of aging by stimulating reactive oxygen species. Nanoemulsion was loaded with fullerene, a strong free ...

The mouse mutant hemoglobin deficit (gene symbol hbd) is characterized by a severe microcytic anemia that is inherited in an autosomal-recessive manner. To assess the mutation's effect on hematopoiesis, unfractionated bone marrow (BM) from either a mutant C57BL6/J-hbd/hbd, Gpi1b/Gpi1b (phenotype symbol HBD), or normal C57BL6/J-+hbd/+hbd, Gpi1b/Gpi1b mouse was injected intravenously into irradia...

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...

Mucous membrane pemphigoid (MMP) is an autoimmune blistering disease that most frequently affects the oral cavity and conjunctivae. Additional skin lesions may appear in about a quarter of patients. The current therapeutic armamentarium mainly based on long-term immunosuppression, which associated with high number adverse events not effective. Here, we investigated effects topical conjunctival ...

From histopathological specimens, endolymphatic hydrops has been demonstrated in association with inner ear disorders. Recent studies have observed findings suggestive of hydrops using MRI in humans. Previous studies suggest that vasopressin may play a critical role in endolymph homeostasis and may be involved in the development of Ménière's disease. In this study we evaluate the effect of vaso...

Early manifestations of kidney disease occur in atherosclerosis and activation of TP (thromboxane A(2)) receptors is implicated in atherosclerotic, diabetes, and renal diseases. The purpose of the present study was to analyze, in isolated, perfused mouse kidneys, the participation of TP receptors in renal vasoconstrictions and vasodilatations. In kidneys, taken from wild-type C57BL6, apolipopro...

AIM We investigated differences of metastatic spread of normal proteinase-activated receptor-2 (Par2+/+) melanoma B16 in Par2-/- (knock-out) animals compared to C57Bl6 mice. MATERIALS AND METHODS Nine knock-out mice B6.Cg-F2rl1tm1Mslb/J (Par2-/-) and nine C57Bl6/J controls were subcutaneously inoculated with B16 melanoma tissue cells. Twelve days after inoculation, all primary tumors were rem...
