INTRODUCTION While the use of intraoperative angiography (IA) has been shown to be a useful adjunct in aneurysm surgery, its routine use remains controversial. OBJECTIVE We wished to determine if IA is required in all patients undergoing aneurysm surgery (ie, routine IA) or if intraoperative assessment can reliably predict the need for IA (ie, select IA). METHODS We prospectively evaluated ...

Among bone-marrow-derived (B) lymphocytes exist subpopulations of cells that can be induced to express the markers: surface immunoglobulin (Ig), the antigen associated with the immune response gene (Ia), and the receptor for the third complement component (CR). Inducible cells for the first two markers are found in bone marrow, and inducible cells for all three are in spleen. Experiments were d...

Let F(a,b;c;z) be the classical hypergeometric function and f be a normalized analytic functions defined on the unit disk . Let an operator Ia,b;c(f ) be defined by [Ia,b;c(f )](z)= zF(a,b;c;z)∗f(z). In this paper the authors identify two subfamilies of analytic functions 1 and 2 and obtain conditions on the parameters a,b,c such that f ∈ 1 implies Ia,b;c(f )∈ 2.

Intra-arterial (IA) chemotherapy for head and neck cancer is effective and multiple IA concurrent chemoradiation (CCRT) protocols have been reported. However, the role of IA CCRT in the multimodality treatment of head and neck cancer is still controversial. We have treated 5 cases of unresectable T4 maxillary sinus squamous cell carcinoma with IA cisplatin (CDDP) and docetaxel (DOC) and CCRT wi...

We have previously reported that the Ia specificities, coded for by the I region within the H-2 complex, appear to consist predominantly of carbohydrate. This conclusion was reached by examining low molecular weight Ia-bearing oligosacharides isolated from mouse serum. We now report hapten-inhibition studies which indicate that the binding of both allogeneic and xenogeneic anti-Ia antibodies to...

The Ly and Ia phenotypes of T lymphocytes involved in different functions were characterized by the use of specific antisera. T cells responsible for delayed-type hypersensitivity (DTH) and for helper functions were found to be Ly-1+,2- in contrast to cytotoxic T cells and T cells responsible for suppression of antibody responses which were Ly-1-,2+. Unlike some primed helper cells, T cells inv...

Ia specificities 1-10 were detected on LPS-stimulated splenic lymphocytes and on Con A-stimulated spleen, lymph node, and thymus blasts by direct cytotoxic tests. Since Ia antigens are not readily detectable on resting thymocytes, our results suggest that T cells require some signal before they exhibit full expression of Ia specificities. Absorption-elution studies indicated that most of the Ia...

Antigenic stimulation is associated with enhanced adhesion between T cells and antigen-presenting cells (APC). Binding of ligands to the T cell antigen receptor activates the adhesion function of lymphocyte function-associated molecule 1 (LFA-1; CD11a/CD18). We demonstrate here that ligand binding to major histocompatibility complex class II (Ia) molecules also activates LFA-1 function, providi...
