extensive research in the last decade has defined that most chronic diseases display dysregulation of multiple cell signaling pathways that have been linked to inflammation. neuroinflammation is reaction of living nervous tissue to injury. it may be initiated in response to neurological disease. including infection, traumatic brain injury, toxic metabolites and autoimmunity. the natural compoun...
A total of 154 samples of marine (n=51) and freshwater fish (n=103) were obtained from fish markets in Elazig Province of eastern Turkey. These samples were tested for Campylobacter, Listeria and Salmonella using culturing and biochemical methods. Campylobacter failed to be detected in any freshwater or marine fish samples. Listeria was detected in 22 and 14 of gill and skin samples from freshw...
Coastal ecosystems of Bushehr are shallow environments subject to human impacts, including shrimp aquaculture and urban expansion activities. A spatial-temporal study was conducted in order to assess the actual ecological status of the creeks, estuary and marine sites on the basis of their taxonomic composition and density of mesozooplankton. Zooplankton species distribution and abundance data ...
Marine debris is listed among the major perceived threats to biodiversity, and is cause for particular concern due to its abundance, durability and persistence in the marine environment. An extensive literature search reviewed the current state of knowledge on the effects of marine debris on marine organisms. 340 original publications reported encounters between organisms and marine debris and ...
چکیده: حمل و نقل دریایی ار آنجا صاحب اهمیت شده است که بیشتر کره زمین را آب فراگرفته و تا پیشرفت علم تنها وسیله ارتباطی جوامع دریا و خشکی بوده است حمل و نقل دریایی ار اهمیت بسیاری برخوردار شده است به طوری که از راه دریا بیش از 80% از کل تجارت جهان صورت می پذیرد؛ اما این امر با مشکلات بسیاری به خصوص از لحاظ اجرایی روبرو بوده است ؛ به این دلیل و بسیاری از دلایل دیگر، مراکز مرتبط با حمل و نقل دریا...

the potential of marine actinobacteria particularly streptomyces as a single cell protein (scp) feed for the growth of ornamental fish, xiphophorus helleri has been investigated. the streptomyces strains used as scp were isolated from the marine sponges, namely callyspongia diffusa , mycale mytilorum , tedania anhelans and dysidea fragilis . six scp feeds were prepared and their effects were co...
In 2001, the Canadian Councils of Resource Ministers (CCRM) named biodiversity reporting as a priority. As a result, the Biodiversity Outcomes Framework was developed to identify and link current and future priorities related to sustaining Canadian biodiversity, to engage Canadians on the planning and implementation of these priorities, and to report on progress. In 2006, the CCRM identified th...
Significant warming has been observed in every ocean, yet our ability to predict the consequences of oceanic warming on marine biodiversity remains poor. Experiments have been severely limited because, until now, it has not been possible to manipulate seawater temperature in a consistent manner across a range of marine habitats. We constructed a "hot-plate" system to directly examine ecological...
