conclusion we constructed and validated a ct colonography phantom with correct density allowing performance of reproducible experiments. materials and methods we found 15 different phantom designs by literature search and compared their advantages and disadvantages based on their description and images. we tested various materials for density and mechanical properties and constructed a phantom ...
Polypectomy-snare entrapment is a rare but serious complication of colonoscopy, frequently requiring surgical intervention. We report a case of polypectomysnare entrapment successfully treated using a novel endoscopic “zip-line” approach that, to our knowledge, has not been previously reported.

Maintaining deciduous teeth in function until their natural exfoliation is absolutely necessary. Vital pulp therapy (VPT) is a way of saving deciduous teeth. The most important factors in success of VPT are the early diagnosis of pulp and periradicular status, preservation of the pulp vitality and proper vascularization of the pulp. Development of new biomaterials with suitable biocompatibility...
Xylan extracts from southern US hardwood were used for the adsorption of both hardwood and softwood pulp. Pulp beatability and physical strength properties were determined and compared with those of the conventional Kraft pulp and pre-extracted modified Kraft pulp. The results indicated that hemicelluloses adsorption greatly improved pulp beatability. Compared to conventional Kraft pulp, a sign...
Effects of Feeding Citrus Pulp Supplements on the Performance of Calves in a Preconditioning Program
Dehydrated citrus pulp and citrus pulp-protein supplements were evaluated as potential supplements for a preconditioning program. The supplements compared were no supplement, citrus pulp alone, citrus pulp with urea, and citrus pulp with added UIP. Supplemented cattle produced greater gains than unsupplemented cattle. Citrus pulp with added UIP produced the greatest ADG (0.95 lb/hd/d) whereas c...
