Street-vended ready-to-eat food sold in Egypt, including sandwiches and dishes of traditional food, was examined for the presence of Listeria species. Out of 576 samples, 24% were found to contain Listeria species. L. monocytogenes and L. innocua were isolated from 57% and 39% of the contaminated samples, ...
Trypsin from the pyloric caeca of Pacific cod (Gadus macrocephalus) was easily prepared by affinity chromatography on Benzamidine Sepharose 6B and gel filtration on Superdex 75. Pacific cod trypsin was composed of three isozymes, and their molecular masses were estimated 23,756.34 Da, 23,939.62 Da, ...
Viscera of mackerel (Scomber sp.) were defatted by supercritical carbon dioxide (SCO2) treatment. Trypsin (SC-T) was then extracted from the defatted powder and purified by a series of chromatographies including Sephacryl S-200 and Sephadex G-50. The purified SC-T was nearly homogeneous on SDS-PAGE, ...
Marine bioresources produce a great variety of specific and potent bioactive molecules including natural organic compounds such as fatty acids, polysaccharides, polyether, peptides, proteins, and enzymes. Lectins are also one of the promising candidates for useful therapeutic agents because they can ...
Previous studies have indicated that tire tread particles are toxic to aquatic species, but few studies have evaluated the toxicity of such particles using sediment, the likely reservoir of tire wear particles in the environment. In this study, the acute toxicity of tire and road wear particles (TRWP) ...
In this paper, we define the method that is used to merge high-resolution multisensor chlorophyll-a (chl-a) data on the Ireland-Biscay-Iberia Regional Ocean Observing System area from 1998 to the present at a resolution of 1.1 km. The method is based on geostatistics and is known as kriging. The merged ...
A GPS-based wireless ad hoc network is proposed for marine monitoring, search, and rescue applications in Vietnam. The network routing protocol and algorithm are evaluated using Network Simulator 2 software. The results indicate a success rate of packages transmission higher than 85% and show the great ...

Background. Leptospirosis is a spirochetal zoonosis with complex clinical features including renal and liver failure. Case report. We report the case of a Swiss fisherman presenting with leptospirosis. After initial improvement, refractory septic shock and severe liver and kidney failure developed. ...

With the objective of promoting sustainable costal fishing, we propose a transition to ICT-based fishing that uses real-time information. In this report, we introduce an information and communications technology (ICT)-based approach to sea cucumber dredge net fishing that uses “Marine Broadband Framework”, ...
There are three basic techniques commonly employed to extract data from an undersea sensor: 1. via a fixed wired link to a surface expression. 2. via a pop-up buoy, usually incorporating an RF link. 3. via wireless undersea communications. We suggest that the first is impractical in deep or rough conditions ...
The underwater acoustic (UWA) communication of underwater unmanned vehicle (UUV) is relating to the communication among UUVs or between UUV and hoster. Then the UWA communication becomes more difficult due to its complex acoustic environment, variety of ranges and the limitation of the space and energy ...
All over the world information and communication technologies have a direct impact on the economic development, and socio-cultural value system of society. The inclusion if satellite aided navigation in transportation is well established worldwide. Air and sea travel has been the main beneficiary of ...
