The current study was undertaken in order to assess the risk that different ranaviruses might impose on European sheatfish aquaculture. As the European sheatfish virus (ESV) is a known pathogen causing losses in European sheatfish aquaculture, it was assumed that closely related exotic ranaviruses might also be able to infect European sheatfish and probably cause disease and mortality in this s...

The recent article in the Journal by Fernandez et al (1), pointing out that fish consumption reduces the risk of several types of cancer, is an important work that opens the door to increased prevention of such cancers. Chronic inflammation is one of the risk factors for cancer (2). The results of a recent study suggest that nonsteroidal antiinflammatory drugs may prevent colon cancer by suppre...

A 48-year-old male with no significant past medical history came to the emergency department (ED) because of sudden onset of diffuse myalgia especially in the legs, chest and back. It was associated with mild diaphoresis. Symptoms started acutely as he was driving back home from his work as a cab driver. He denied fever, new medications, recreational drug use, recent illness, significant physic...

Does fish consumption protect against coronary heart disease? If so what are the mechanisms for such protection and how much fish (and of what types) would need to be consumed? Atherosclerosis is apparently rare among Eskimos on a tradititional diet of seal, caribou, and fish but not among those on a western diet.' Necropsy data showed that atherosclerosis was less severe in Canadian Eskimos2 t...

Fish oil products are available with or without prescription and are widely used by patients with ischaemic heart disease (IHD). The interest in fish oils, rich in the long chain n-3 polyunsaturated fatty acids (PUFA), eicosapentaenoic acid (n-3 20:5) and docosahexaenoic acid (n-3 22:6), originates primarily from the pioneering work of Dyerberg and Bang.' Prompted by the low incidence of acute ...

T he antithrombotic action of aspirin depends on inhibition of cyclooxygenase activity' in platelets, thereby reducing thromboxane A2 formation and consequently, their aggregability. In 1978, two important concepts on eicosanoid formation were presented. The first2 was that the vascular wall could utilize endoperoxides released by adhering platelets for the formation of prostacyclin. The second...

Infectious pancreatic necrosis virus (IPNV) is the causative agent of IPN, an important disease of salmonids. IPNV infections result in either sub-clinical or overt disease and the basis of this difference is not well-understood. The objective of the present study was to determine the VP2 gene of the virus associated with the different forms of clinical manifestation. Groups of Atlantic salmon ...

Bee-collected pollen (bee pollen) is reported as a health food with a vast range of nutritional and therapeutic effects. Biochemical and hematological parameters in blood of rainbow trout treated to various concentrations of pollen (0.5, 2.5, 5, 10, 20 and 30 ppm) for 96 h were determined. The levels of total protein, creatinine, chloride and sodium in fish which exposed to different concentrat...

Biliary liver flukes are common parasites in some regions of the world where consumption of raw fresh-water fish is a cultural practice. Clonorchis sinensis and Opisthorchis species are the major biliary liver flukes associated with human disease. Some of these parasites are highly associated with cholan...
