Ir-IA is a dominant autosomal gene(s) which regulates the specific antibody response to several antigens, including three branched, multichain, polypeptide antigens, poly-L(Tyr, Glu)-poly-D,L-Ala--poly-L-Lys; poly-L-(His, Glu)-poly-D,L-Ala--poly-L-Lys; and polyL-(Phe,Glu)-poly-D,a-Ala--poly-L-Lys, abbreviated respectively (T,G)-A--L, (H,G)-A--L, and (Phe, G)-A--L (1). 1 The Ir-lA gene is locate...

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 ...

Aims This study sought to extend the inclusion criteria for hepatocellular carcinoma (HCC) liver transplantation (LT), particularly addressing the safety and effectiveness of pre-LT transarterial chemoembolization (TACE). Materials and Methods Our study included 115 patients with HCC who underwent LT after TACE. The response measured after each TACE session was based on the mRECIST criteria: ...

In this paper, we study user profile matching with privacy-preservation in mobile social networks (MSNs) and introduce a family of novel profile matching protocols. We first propose an explicit Comparison-based Profile Matching protocol (eCPM) which runs between two parties, an initiator and a responder. The eCPM enables the initiator to obtain the comparison-based matching result about a speci...

The level of antibody produced in response to calf skin collagen in mice is influenced by genes which are closely linked to the I region of the H-2 major histocompatibility complex. This influence is shown to be expressed during lymphoid maturation by testing the antibody responsiveness to collagen in two types of chimeric mice. First, high responder and low responder parental strain mice were ...

By employing primary cultures of purified spleen cells from lipopolysaccharide (LPS) responder (C3H/HeN or C57BL/10Sn) or nonresponder (C3H/HeJ or C57BL/10ScN) mice incubated with particulate antigen and LPS prepared by phenol-water extraction (Ph), we have presented evidence that both T cells and macrophages (MO) are required for LPS-induced adjuvanticity. First, MO derived from C3H/HeN spleen...

We have studied the properties of helper T cells specific for sheep erythrocytes (SRBC), keyhole limpet hemocyanin (KLH), or poly-L-(Tyr,Glu)-poly-DL-Ala-poly-L-Lys [(T,G)-A--L]. These T cells differentiated and were primed in vivo in irradiation chimeras constructed of various combinations of F1 and parental bone marrow donors and irradiated recipients. Primed T cells were then tested for help...
