Rabbit synovial cells (SC), articular chondrocytes (AC), and epiphyseal (EC) chondrocytes were grown in vitro. A portion of the spectrum of human pathogenic viruses infective for the cells was determined. Responses of the cells to different viruses or a chemical inducer of interferon varied, with EC responding vigorously and with high titers, AC responding only to chemical inducer and influenza...

The effects of binding inducer and anti-inducer of the Escherichia coli lac operon to the lac repressor were examined by taking advantage of fluorine-19 NMR. The fluorine nucleus was biosynthetically incorporated into the lac repressor with either 5-fluorotryptophan or 3-fluorotyrosine. It is suggested that these small effector molecules influence the operator-binding properties of the tetramer...

In this paper I present the results from a design research project done at the Eindhoven University of Technology. In this project I explored the possibilities of mixing realities using sound. With this mixed reality I explored ways to make people scared for entertainment purposes, comparable to horrormovies or thrill rides. One of the main elements of the concept was to make the device mobile,...

During fetal development, lymphoid tissue inducer cells (LTis) seed the developing lymph node and Peyer's patch anlagen and initiate the formation of both types of lymphoid organs. In the adult, a similar population of cells, termed lymphoid tissue inducer-like cells (LTi-like cells), supports the formation of organized gut-associated lymphoid tissue (GALT) in the intestine, including both isol...

A variety of methods exist for inductive learning of classification rules using crisp sets. In this paper we illustrate an inductive learner that uses fuzzy sets, where the membership functions of the linguistic terms are given in advance. We also show how the induction of conjunctive rules fit into a fuzzy set covering framework (FuzzyBexa) that we introduced before.

Lymphoid tissue-inducer cells are hematopoietic cells essential for the organogenesis of several lymphoid structures during both fetal and adult life, whereas natural killer cells are key effector lymphocytes of the innate immune system. A series of recent reports has identified RORγt(+)NKp46(+) interleukin-22-producing cells in gut and tonsils that share features with both lymphoid tissue-indu...
