Despite intensive investigation, the essential mechanisms of allograft rejection or tolerance have remained obscure. Although there is now no doubt that juvenile as well as adult individuals respond to foreign tissue grafts with production of serum antibodies against the alloantigens (isoantigens) of the donor, the possible roles of such antibodies in graft rejection continue to be controversia...

To investigate the protective effect of quercetin on lipopolysaccharide-induced inflammatory response retinal ganglion cell line 5 cells and to explore its possible molecular mechanism. Retinal were cultured in vitro assigned into blank control group, lipopolysaccharide (1.0 μg/ml) induction lipopolysaccharide+low dose (0.25 lipopolysaccharide+medium (0.5 group lipopolysaccharide+high group. Th...

Agar gel immunodiffusion (AGID) test is a simple and rapid method for the diagnosis of Peste des petits ruminants (PPR) which requires the preparation of potent specific hyperimmune serum. This study deals with the raising of hyperimmune serum against PPR virus in rabbit. Four different inocula included PPR vaccine reconstituted in phosphate buffer saline, PPR antigen suspended in phosphate buf...

Anti-cytomegalovirus (anti-CMV) hyperimmune globulin (HIG) has demonstrated efficacy in preventing CMV disease in solid-organ transplant patients as well as congenital disease when administered to pregnant women. To identify the neutralizing component of cytomegalovirus hyperimmune globulin (CMV-HIG), we performed serial depletions of CMV-HIG on cell-surface-expressed CMV antigens as well as pu...

To investigate the effects and mechanisms of Dexmedetomidine on inflammatory factors mitogenactivated protein kinase related signaling pathways in alveolar lavage fluid mice with acute lung injury induced by lipopolysaccharide. 36 clean-grade male Kunming were randomly divided into blank control group (normal group), lipopolysaccharide-induced model group, lipopolysaccharide+dexmedetomidine 12 ...

This paper investigates the relation between immunity and hardness in exponential time. The idea that these concepts are related originated in computability theory where it led to Post’s program, and it has been continued successfully in complexity theory [9, 13, 20]. We study three notions of immunity for exponential time. An infinite set A is called • EXP-immune, if it does not contain an inf...

A latex coagglutination assay was developed to identify rough (R) isolates of Brucella. Latex beads were coated, via protein A, with either an anti-Brucella rough-lipopolysaccharide (R-LPS) monoclonal antibody (MAb) or an anti-Brucella 25-kDa outer membrane protein (Omp25) MAb. Slide agglutination tests were done for 68 strains of Brucella spp., including type strains of all biovars as well as ...

Complexes containing lipopolysaccharide (LPS) and three outer membrane proteins (OMPs) are released by gram-negative bacteria incubated in human serum and into the circulation in an experimental model of sepsis. The same OMPs are bound by immunoglobulin G (IgG) in the cross-protective antiserum raised to Escherichia coli J5 (anti-J5 IgG). This study was performed to identify the three OMPs. The...

background: the contribution of neuroinflammation in alzheimer’s disease (ad) has been widely reported. the effects of female gonadal hormones in both neuroinflammation and brain cognitive functions have also been well considered. objectives: in the present study, the possible protective role for endogenous ovarian hormones against learning and memory impairment as well as brain tissues oxidati...
