Condensation-ring Expansion Reaction of Formyl[2.2.1]bicyclic Carbinols with Para-substituted Phenyl Amines: Application to the Preparation of [3.2.1]bicyclic N-aryl-1,2,3-oxathiazolidine-2-oxide Agents
[[abstract]]Individual reaction of camphene-derived endo-formyl[2.2.1]bicyclic carbinol and that of camphor-derived exo-formyl[2.2.1]bicyclic carbinol with parent and para-substituted phenyl amines gave regio- and stereospecific corresponding [3.2.1]bicyclic (para-substituted) phenyl amino ketones. Mechanism of each reaction was discussed. Some camphor-derived [3.2.1]bicyclic amino ketones were reduced to [3.2.1]bicyclic (para-substituted) phenyl amino alcohols, which were then treated with mesyl chloride to provide [3.2.1]bicyclic N-phenyl/aryl-1,2,3-oxathiazolidine-2-oxide agents. The mechanism of this final reaction was discussed as well.[[note]]SC

Evaluation of management factors affecting the relative success of a Brook Trout eradication program using YY male fish and electrofishing suppression
Removal of non-native fish populations can be crucial to the conservation of native species, but often presents a complex challenge for managers. The goal of Trojan Y chromosome (TYC) programs is to skew the non-native sex ratio until only males remain, leading to eradication. We present results from a simulation model used to explore effects of alternative management approaches on an in-progress mechanical removal and TYC program to eradicate non-native Brook Trout. Simulation results indicated that stocking fingerling YY males (~137 mm) was more effective than stocking catchable-sized YY males (~230 mm), although questions about inter-cohort competition warrant further investigation. Increasing the proportion of mature fingerling YY males reduced treatment time by increasing the number of YY male spawners and increasing density-dependent mortality on young, mature wild Brook Trout. Maximizing the spatial distribution of YY male releases may be crucial to program success but is also dependent upon immediate dispersal movements. Principles derived from our results can be broadly applied to the management of other aquatic invaded systems using TYC programs to eradicate non-native species.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

Wheat gluten hydrolysate potently stimulates peptide-YY secretion and suppresses food intake in rats
The study was aimed to compare the satiating effect of various protein hydrolysates in rats and examine the underlying mechanism associated with the satiety hormones. Food intake and portal satiety hormone levels were measured in rats. Enteroendocrine cell-lines were employed to study the direct effect of protein hydrolysates on gut hormone secretions. The results showed that oral preload of wheat gluten hydrolysate (WGH) suppressed food intake greater and longer than other hydrolysates. The portal peptide-YY levels in WGH-treated rats at 2 h and 3 h were higher than those in control- and lactalbumin hydrolysate (LAH)-treated rats. In a distal enteroendocrine cell model, WGH more potently stimulated glucagon-like peptide-1 secretion than LAH, and the effect was largely enhanced by pepsin/pancreatin digestion of WGH. These results suggest WGH is potent in activating enteroendocrine cells to release satiety hormones leading to the prolonged suppression of food intake
Block TERM factorization of block matrices
Reversible integer mapping (or integer transform) is a useful way to realize lossless coding, and this technique has been used for multi-component image compression in the new international image compression standard JPEG 2000. For any nonsingular linear transform of finite dimension, its integer transform can be implemented by factorizing the transform matrix into 3 triangular elementary reversible matrices (TERMs) or a series of single-row elementary reversible matrices (SERMs). To speed up and parallelize integer transforms, we study block TERM and SERM factorizations in this paper. First, to guarantee flexible scaling manners, the classical determinant (det) is generalized to a matrix function, DET, which is shown to have many important properties analogous to those of det. Then based on DET, a generic block TERM factorization, BLUS, is presented for any nonsingular block matrix. Our conclusions can cover the early optimal point factorizations and provide an efficient way to implement integer transforms for large matrices.Computer Science, Information SystemsSCI(E)3ARTICLE4421-4364
