A collection of articles dealing with a question of Jewish involvement in the interfaith and intercultural dialogue in the postwar Europe, Israel and the United States. The leitmotif of the volume is the Jewish attitude towards otherness and its relation to the responsibility for the other. The contributions pertain to the status of the non-Jewish residents of Israel, the social involvement into p

Purpose: We investigated whether a low-field MR unit (0.2 T) could demonstrate and determine the size of the lymph nodes in the hepato-duodenal ligament that were previously found on ultrasound. Material and Methods: Eighteen patients were examined with ultrasound, MR and liver biopsy on consecutive days. Results: Two-thirds of the enlarged nodes detected by ultrasound were also detected with the

Paper copies of digital radiographs printed with the continuous ink-jet technique have proved to be of a high enough quality for demonstration purposes. We present a study on the image quality of ink-jet printed paper copies of digital chest radiographs, based on receiver operating characteristic (ROC) analysis. Eighty-three digital radiographs of a chest phatom with simulated tumors in the medias

Thirty-two consecutive patients with a histological diagnosis of chronic active hepatitis were examined with liver biopsy, laboratory tests and ultrasonography of the hepato-duodenal ligament to investigate the possible correlation between enlarged lymph nodes in the hepato-duodenal ligament and biochemical activity, histological activity and/or humoral immunoreactivity. We found a significant cor

Myocardial 201Tl emission computed tomography was performed on 25 normal subjects and 27 patients with angiographically significant coronary artery disease. A semi-automatic computer program was designed to define the left ventricular myocardial volume in all short axis sections. Within this volume the relative mean myocardial pixel count was calculated. This parameter was found to separate the 2

Pulmonary sarcoidosis was studied with respect to lung mechanical properties and to the influence of these on lung volumes. Sixty six patients, with histological support for the diagnosis of sarcoidosis, and radiological signs of pulmonary involvement, i.e. stage II or III, were studied. The static pressure/volume (P/V) curves showed that the static elastic recoil pressure (PelL) tended to be incr

Ninety-eight digital radiographs of a chest phantom with simulated tumors in the mediastinum and left lung and a pneumothoraxsimulation in the right hemithorax were compared with the corresponding examinations saved on optical disk and viewed on a 1000-line monitor. The examinations were reviewed by 7 radiologists with different experience, and receiver operating characteristic (ROC) curves were c

If we find life on another world, it will be an extremely important discovery and we will have to take great care not to do anything that might endanger that life. If the life we find is sentient we will have moral obligations to that life. Whether it is sentient or not, we have a duty to ourselves to preserve it as a study object, and also because it would be commonly seen as valuable in its own If we find life on another world, it will be an extremely important discovery and we will have to take great care not to do anything that might endanger that life.

Rhizopus arrhizus lipase immobilized on porous polypropylene was used in an acidolysis reaction in toluene at low water activity (0.11) to exchange the fatty acid in the sn-1-position of digalactosyldiacylglycerol (DGDG). Without extra precautions, an yield of only about 20% was obtained, mainly due to side reactions; incorporation of an extra acyl group on the primary hydroxyl of the digalactosyl

Immobilised 1,3-specific lipase from Rhizopus arrhizus was used as catalyst for the esterification of dl-glycero-3-phosphate and fatty acid or fatty acid vinyl ester in a solvent-free system. With lauric acid vinyl ester as acyl donor, a(w)95%). With oleic acid, maximum conversions of 55% were obtained at low water activities. Temperatures below melting point of the product favored precipitation a

Lipase from Penicillium roquefortii immobilized on porous polypropylene particles was used for enzymatic preparation of 1,2-diglycerides by alcoholysis in organic media. A screening of commercially available lipases showed that lipases from Penicillium species produced high amounts of 1,2-diglycerides from triglycelirles. Reaction parameters such as solvent, alcohol, water activity, and fatty acid

In plants, cells differentiate according to their position with relation to their cell neighbours. Monoclonal antibody (MAb) probes to polysaccharide epitopes, present at the surfaces of all plant cells, have defined a family of proteoglycan antigens which signify cellular position. These MAbs have been used to sort the single cells present in carrot somatic cell cultures on the basis of the prese
