Detection of Toxoplasma gondii infection is essential in pregnant women and immunosuppressed patients. Numerous studies have shown that the recombinant production of several Toxoplasma antigens, including dense granule antigens (GRAs) has high potential as diagnostic reagents. In the present study, we produced GRA2 using Pichia pastoris system. RNA of T. gondii RH strain tachyzoite was used as ...

Recently human interleukin-3 (IL-3) produced by molecular cloning was characterized as a growth factor for basophils and eosinophils in human bone marrow cultures. Since we found a similar activity of the human factor on simian bone marrow cells, we investigated the in vivo effects of recombinant human (rh) IL-3 in healthy rhesus monkeys (n = 10). rh IL-3 was administered subcutaneously (SC) to...

introduction: to write a computational program to calculate the average glandular dose in mammography with rh-rh target-filter and also use it as an accurate and fast method of dose calculation founder different situations. materials and methods: in this research, the sobol-wu parameters are used to write a fortran code for glandular dose calculation in rh-rh target-filter mammograms. the code ...

The mechanisms through which LH-RH antagonists suppress gonadotroph functions and LH-RH receptor (LH-RH-R) production are incompletely understood. To elucidate these mechanisms, we investigated the effects of Cetrorelix on the mRNA expression of pituitary LH-RH-R and luteinizing hormone (LH) secretion in three experimental systems with different pituitary LH-RH environments. Ovariectomy induced...

Rose hip powder (RHP) alleviates osteoarthritis (OA) due to its anti-inflammatory and cartilage-protective properties. Substances contained in RHP might contribute to its clinical efficacy. The activity of two RHP (i.e., RH-A, from the whole fruit, RH-B, from fruits without seeds) was investigated in human peripheral blood leukocytes (PBL) and primary chondrocytes (NHAC-kn). RH-A and RH-B dimin...

The metallophilic interactions were investigated within chains of oppositely charged rhodium carbonyl complexes. The cationic [Rh(CO)(2)(L)](+) (L = 2,2'-bipyridine and 1,10-phenanthroline) and anionic [RhCl(2)(CO)(2)](-) units were self-assembled into one dimensional rhodium chains supported by electrostatic interactions. The array of Rh centers in {[Rh(CO)(2)(2,2'-bpy)][RhCl(2)(CO)(2)]}(n) wa...

 This study was aimed to detect anti-Toxoplasma gondii antibodies in cats infected with Rh strain of T. gondii by using an immunoblotting method. For this, cats were experimentally infected using tachyzoites harvested from Vero cell cultures. Tachyzoites were then lysed and transferred to polyacrylamide gels followed by blotting to PVDF membranes. An immunoblotting was performed using these mem...
