Acid soluble collagen (ASC) was extracted from the skins of young and adult Nile perch (Lates niloticus) using 0.5 M acetic acid and precipitation using 0.9 M NaCl. The ASC yields, on a dry weight basis, were 63.1 and 58.7%, respectively for young and adult fish skins. SDS PAGE showed the collagens to contain two alpha components (a1 and (2). ASC from Nile perch was found to contain more imino ...

The goal of the Nile project is to manage distributed computing resources, making an arbitrarily large cluster of commodity computers appear to the user as a seamless uniprocessor environment. This paper describes Nile's software architecture. 1 The Nile Project The Nile project 2,4] is building a distributed computing solution for CLEO III 3]. The goal is to provide a self-managing, fault-tole...

Nile perch (Lates niloticus) suddenly invaded Lake Victoria between 1979 and 1987, 25 years after its introduction in the Ugandan side of the lake. Nile perch then replaced the native fish diversity and irreversibly altered the ecosystem and its role to lakeshore societies: it is now a prised export product that supports millions of livelihoods. The delay in the Nile perch boom led to a hunt fo...

West Nile virus ecology has yet to be rigorously investigated in the Caribbean Basin. We identified a transmission focus in Puerto Barrios, Guatemala, and established systematic monitoring of avian abundance and infection, seroconversions in domestic poultry, and viral infections in mosquitoes. West Nile virus transmission was detected annually between May and October from 2005 to 2008. High te...

West Nile virus (Flaviviridae: Flavivirus) is a serious infectious disease that recently spread across the North America continent. A spatial analysis tool was developed on the ArcMap 9.x platform to estimate potential West Nile virus activity using a spatially explicit degree-day model. The model identifies when the virus Extrinsic Incubation Period (EIP) is completed within the vector longevi...

BACKGROUND The spread of West Nile virus across North America and evidence of transmission by transfusion prompted the U.S. Food and Drug Administration to encourage the development of methods to screen the blood supply. OBJECTIVE To assess the cost-effectiveness of nucleic acid amplification testing for West Nile virus in the U.S. blood supply. DESIGN Markov cohort simulation. DATA SOURC...

IMPORTANCE After progressive declines over recent years, in 2012 West Nile virus epidemics resurged nationwide, with the greatest number of cases centered in Dallas County, Texas. OBJECTIVE To analyze the epidemiologic, meteorologic, and geospatial features of the 2012 Dallas West Nile virus epidemic to guide future prevention efforts. DESIGN, SETTING, AND PATIENTS Public health surveillanc...

We report a molecular modeling study, coupled with spectroscopy experiments, on the behavior of two well known organic dyes, nile blue and nile red, when interacting with B-DNA. In particular, we evidence the presence of two competitive binding modes, for both drugs. However their subsequent photophysical behavior is different and only nile blue is able to induce DNA photosensitization via an e...

Cranial nerve involvement has been reported with West Nile Virus infection. We report a case of diplopia secondary to West Nile Virus meningitis.

To develop attenuated bacteria as potential live vaccines, sparfloxacin was used in this study to modify 40 isolates of Streptococcus agalactiae. Majority of S. agalactiae used in this study were able to develop at least 80-fold resistance to sparfloxacin. When the virulence of the sparfloxacin-resistant S. agalactiae isolates were tested in 10-12g Nile tilapia by intraperitoneal injection at d...
