The development of nonsurgical contraceptives for cats may facilitate population control of the species. The purpose of this study was to investigate the utility of GnRH for immunocontraception of male cats. Male cats (n=12) were divided into groups of three and were immunized once with 0 (sham), 50, 200, or 400 microg synthetic GnRH coupled to keyhole limpet hemocyanin and combined with a myco...

The administration of soluble mouse thyroglobulin (MTg) in conjunction with bacterial lipopolysaccharide (LPS) led to the termination of natural tolerance to MTg in mice. The extent of autoimmunity correlated with responsiveness to MTg, previously shown by the injection of MTg in complete Freund's adjuvant (CFA) to be dependent upon the H-2 haplotype. In good responder B10.BR (H-2k) mice given ...

CD4(+)CD25(+high) T cells are potent regulators of autoreactive T cells. However, it is unclear how regulatory CD4(+)CD25(+high) cells discriminate between desirable inflammatory immune responses to microbial Ags and potentially pathologic responses by autoreactive T cells. In this study, an in vitro model was created that allowed differential activation of regulatory CD4(+)CD25(+high) and resp...

Background & Objective: Dangerous O is very important to transfusion medicine and there has been reports by Food and Drug Administration (FDA) regarding some death relating incidences. As high iso-antibody production is closely associated with different immune reactions, a survey on the different immune response of dangerous O donors can lead to understanding their immune respo...

Background The aim of the present study is to investigate the effectiveness responder rate of Electroconvulsive therapy, ECT, in clinical routine work and to define clinical characteristics predictive of response to ECT. The main hypothesis is that the effectiveness responder rate of ECT might be lower in clinical routine than in controlled trials. Methods This is a population-based study of al...

The most common ocular side effect of glucocorticoid (GC) therapy is GC-induced ocular hypertension (OHT) and GC-induced glaucoma (GIG). GC-induced OHT occurs in about 40% of the general population, while the other 60% are resistant. This study aims to determine the genes and pathways involved in differential GC responsiveness in the trabecular meshwork (TM). Using paired bovine eyes, one eye w...

BACKGROUND Optimization of the immunoglobulin (Ig) yield in bovine milk used as therapeutic immune milk or whey for the prevention of Clostridium difficile-associated diarrhea in humans is of great importance to improve the economic efficiency of production. Individual dairy cows have diverse immune responses upon vaccination, resulting in a variable Ig yield in blood and milk. Therefore, it is...

Previous studies had shown that sub-inhibitory concentrations of silver sulphadiazine (AgSD) stimulated the production of Toxic Shock Syndrome Toxin-1 in certain strains (responder strains) of Staphylococcus aureus and that protease production was also affected. No changes were detected in other strains (non-responders). Extracellular proteins from eleven responder and non-responder strains gro...

To approach the mechanism that determines Ir gene-controlled high or low responsiveness to whole proteins, such as sperm whale myoglobin (SWMb), we compared the repertoires of high and low responder haplotype-restricted T cells for different myoglobin epitopes by limiting dilution frequency analysis. Poisson analysis was performed using long-term limiting dilution cell lines of (B10.BR [low] X ...
