The main conclusion from this study is that C3 receptors are not required for the generation from B cells of a thymus-dependent 7S antibody response. The requirement for C3 receptors on the precursors of antibody-forming cells was studied in an adoptive transfer system using thoracic duct lymphocytes (TDL) from primed rats as a source of precursors and irradiated recipients as hosts. 7S precurs...

The origin of immunoglobulin on the surface of TDL in the rat has been studied by comparing the binding of purified alloantibodies recognizing the Ig-1a allotype of rat light chain, with that of rabbit antirat Fab antibodies. Both reagents labeled all TDL from rats of the DA strain (Ig-1a) with two categories of cells being detected; one binding 100-2,000 molecules of antibody, the other 10,000...

El Programa de Estimulación Lingüística Expresión Oral (PELEO) está orientado a la intervención del lenguaje para ser utilizado con niños Retraso Lenguaje (RL) y Trastorno Desarrollo (TDL). Su diseño, visual ágil, emplea láminas imágenes que se muestran los (basadas en bits inteligencia Doman). objetivo principal artículo es comprobar su eficacia niñas RL TDL tres seis años. La metodología una ...

The fluorescence activated cell sorter was used to determine the class of immunoglobulin on the thoracic duct lymphocytes (TDL) which carried IgG memory. Although only about 3% of all TDL carried membrane IgG these cells accounted for most, if not all, of the adoptive IgG anti-DNP response. It is concluded that both CR+ and CR- cells mediating IgG memory in rat TDL bear the same class of membra...

AIM In demyelinating disease spectrum, tumor-like (tumefactive) demyelinating lesions (TDL) are rarely seen. Atypical imaging and clinical features of these lesions may cause misdiagnosis of tumor or abscess. MATERIAL AND METHODS 25 patients with TDL in our center were followed and clinical, magnetic resonance imaging (MRI), magnetic resonance spectroscopy, cerebrospinal fluid (CSF) findings ...

This report introduces the notion of transparent distribution of real time software components. Transparent distribution means that (1) the functional and temporal behavior of a system is the same no matter where a component is executed, (2) the developer does not have to care about the differences of local versus distributed execution of components, and (3) the components can be developed inde...

Abstract Charge exchange (CX) between highly charged ions and neutrals within the geocorona heliosphere introduces a problematic background for every X-ray observation. For H-like ? states each n shell are degenerate. The majority of CX spectral models rely on calculated -resolved cross sections, distribution is assumed to follow one several analytical expressions. Laboratory data validate thes...

10 acid hydrolases known to be lysosomal in other tissues were detected in rat thoracic duct lymphocytes (TDL). Except for cathepsin D, all these enzymes occurred in lower levels in TDL than in rat spleen. Fractionation by means of differential centrifugation revealed two types of distribution patterns. Most of the total cathepsin D activity appeared in a high-speed supernatant (S), whereas the...

Temporal reasoning and temporal query languages present diicult research challenges , which are slowly yielding to the combined attack of many investigations motivated by the theoretical interest and practical import of the problem. In this paper, we subscribe to TSQL2 insofar as practical requirements for a query language are concerned, but we propose a solution that overcomes its shortcomings...

We compare Temporal Difference Learning (TDL) with Coevolutionary Learning (CEL) on Othello. Apart from using three popular single-criteria performance measures: i) generalization performance or expected utility, ii) average results against a hand-crafted heuristic and iii) result in a head to head match, we compare the algorithms using performance profiles. This multi-criteria performance meas...
