Eight of 1 1 children of a known Fletcher taming celite or kaolin were sensitive to factor-deficient individual were found to Fletcher factor deficiency, while one rehave normal activated partial thromboagent containing ellagic acid did not deplastin times, normal levels of factors VIII, tect this abnormality. The finding of an IX, Xl, and XII, and a mean Fletcher factor abnormal partial thromb...

A method for the isolation, from mosaic-diseased Turkish tobacco plants, of a crystalline protein possessing the properties of tobacco mosaic virus has been described (1, 2). The method consists essentially in precipitation of the globulin fraction from a dilute disodium phosphate extract of frozen, macerated, infected plants with ammonium sulfate, and the removal of most of the remaining color...

Phosphonylated azaheterocycles are an important class of compounds with high biological potential as conformationally restricted bioisosteres of amino acids. Therefore, it is of interest to synthesize conformationally constrained amino phosphonates. We wanted to investigate possible routes via ring opening of alpha-amino phosphonates with an oxanorbornene skeleton, as these can be synthesized w...

The apparent digestibility coefficients (ADC) of unprocessed and processed pea, canola and flax products were determined on diets, in which 30% of a reference diet was replaced by each test ingredient. Celite was used as an indigestible marker for measuring apparent digestibility coefficients indirectly. The trial was conducted in a semi-closed recirculating system using 5 tanks per diet with 4...

Vegetative shoots of Arizona cypress (Cupressus arizonica Greene) were found to contain an estimated 40 to 70 mug of gibberellin-like activity per kg. Based on elution patterns of silicic acid and celite partition columns, mobilities on thin layer chromatograms and specificity of the cucumber, d-3 dwarf maize, dwarf pea, and barley half seed bioassays it was possible to determine that the tissu...

Bioemulsans are amphipathic proteins and/or polysaccharides that stabilize oil-in-water emulsions. Bioemulsans are produced by a wide diversity of microorganisms and have potential applications in the food, paper, paint, bioremediation, agriculture, detergent and cosmetics industries. The production of the RAG-1 emulsan has been studied in batch-fed fermentors via self-cycling fermentation and ...

The activated clotting time (ACT) is used frequently for monitoring blood anticoagulant response with heparin before, during, and after cardiopulmonary bypass (CPB). Many cardiac procedures involving CPB require reduction of the patient's blood temperature and use of the serine protease inhibitor, aprotinin. Three different methods of ACT measurement were compared to show the effects of differe...
