As part of a survey of fish diseases, lake whitefish (Coregonus clupeaformis) were collected in fall 1995 from the St. Lawrence River 15 km upstream of Quebec City, Quebec, Canada, to assess the prevalence of liver lesions. A total of 141 fish were captured and necropsied, and three standard sections of liver were taken for histological examination. Prevalences of altered hepatocyte foci, hepat...

Diffusion coefficients of a broad range of molécules with molecular weight ranging from 100 to 800 g/mol hâve been measured in polypropylene, by solid/solid contact methods (without liquid contact), at 40°C. The behaviors of thé différent molécules are compared to those of linear alkanes. The diffusion coefficients are correlated to parameters describing size, shape, and flexibility of thé molé...

One of the conclusions of the 1999 COL report on the status of virtual education development was that it was more rhetorical than real. Now, two years later, it appears to be both more rhetorical and more real. And the gap is closing between the reality and the rhetoric! However that depends on where you live. If you reside in a developing country, for example, the vision you have for virtual e...

The objectives of this study were to determine the prevalence, characterization and antibiotic resistance of Pasteurella multocida isolated from calves with respiratory infection in Iran. P. multocida was detected in 141/169 bovine respiratory infection cases on Iranian dairy and beef farms. P. multocida were grouped into serogroups A (126/141), D (12/141), and B (3/141). Of the P.  multocida i...

A cDNA from the putative ovarian tumor (otu) locus of the Drosophila melanoqaster X-chromosome was isolated from a Canton S ovary library using a genomic probe. The otu gene is essential for female fertility, and produces a variety of ovarian phenotypes when mutant (1). The cDNA corresponds tc an abundant 3.2 kb message present in nurse cells and the developing oocyte (2,3). A 2433 b.p. open re...

We present, for both minkowskian and euclidean signatures, short derivations of the diagonal Einstein metrics for Bianchi type II, III and V. For the first two cases we show the integrability of the geodesic flow while for the third case a somewhat unusual bifurcation phenomenon takes place: for minkowskian signature elliptic functions are essential in the metric while for euclidean signature o...

BACKGROUND The purpose of this study was to delineate the long-term prognosis and factors we have noted in our 25 years of experience treating patients suffering from biliary atresia (BA) who have undergone Kasai's operation. METHODS We studied 141 patients (69 male and 72 female infants) who underwent Kasai's operation at the National Taiwan University Hospital between 1976 and 2000. Factors...

The soluble receptor for advanced glycation end-products (sRAGE) is shown to mitigate pro-inflammatory effects triggered by ligation of RAGE with N(ε)-carboxymethyl-lysine (CML)-AGE or other ligands. We examined the associations among host, lifestyle, and genetic determinants of CML-AGE or sRAGE and risk of pancreatic cancer in the prospective ATBC Study. We obtained baseline exposure informati...

Human glioblastoma is one of the most malignant types of brain tumor in the world. In the present study, the functional mechanisms of microRNA-141 (miR-141) were assessed, and the potential role of miR-141 as a prognostic biomarker in glioblastoma was examined. The gene expression of miR-141 in glioblastoma cell lines and glioblastoma tumors was assessed by reverse transcription-quantitative po...
