BACKGROUND Serological diagnosis of Toxoplasma gondii infection using crude antigens may not be more accurate. To increase the diagnostic potency of antigens, isolation of their immunogenic fractions could be useful. The current research adopted to obtain an affinity isolated fraction from RH strain using CNBr Sepharose 4B column coupled with infected mice sera helping in detection of IgM and I...

BACKGROUND An acellular Pertussis (aP) vaccine containing recombinant genetically detoxified Pertussis Toxin (PTgen), Filamentous Hemagglutinin (FHA) and Pertactin (PRN) has been developed by BioNet-Asia (BioNet). We present here the results of the first clinical study of this recombinant aP vaccine formulated alone or in combination with tetanus and diphtheria toxoids (TdaP). METHODS A phase...

The dog parasite Dirofilaria immitis can infect humans. Patients with pulmonary dirofilariasis were tested for immunoglobulin G (IgG) antibodies against the surface protein of Wolbachia, the bacterial endosymbiont of D. immitis. These patients showed significantly higher IgG titers than healthy individuals from areas in which D. immitis was endemic as well as areas in which it was not endemic. ...

The N7/O6 equatorial binding interactions of the antitumor active complex Rh(2)(OAc)(4)(H(2)O)(2) (OAc(-) = CH(3)CO(2)(-)) with the DNA fragment d(GpG) have been unambiguously determined by NMR spectroscopy. Previous X-ray crystallographic determinations of the head-to-head (HH) and head-to-tail (HT) adducts of dirhodium tetraacetate with 9-ethylguanine (9-EtGH) revealed unprecedented bridging ...

toxoplasma gondii is an apicomplexan parasite that infects human and almost all warm-blooded animals. the life cycle of the parasite includes an asexual reproduction in intermediate hosts (mammals and birds) and a sexual reproduction in definitive hosts (felidae). cats are both the intermediate and the definitive host for t. gondii. the aim of this study was to investigate anti-t. gondii antibo...

Toxoplasma gondii is an intracellular protozoan parasite that causes toxoplasmosis and is of medical importance in pregnant women and immunosuppressed patients. In recent years, many methods have been developed for the detection of infection caused by this parasite; however, most of the developed methods are not adequately sensitive. The dense granular antigen (GRA) ...

INTRODUCTION Previous numerous papers by the senior author dealt with the human serum factor referred to as anti-antibody which is specifically directed against IgG antibodies that underwent molecular transformation in the course of the reactions with their corresponding antigens. The reactions of this serum factor could be conveniently detected by means of agglutination of Rh-positive erythroc...

Uncoupling protein 1 (UCP1) expressed by the brown adipose tissue (BAT) in mitochondrial crista acts as a homeostatic thermogenerator of eutherians. The evaluation UCP1 expression BAT offers significant scientific insight, especially studies targeting limited areas such periarterial and pericardial regions small experimental mammals. However, negligible amount this would render general quantita...
