The parasitic nematode Hysterothylacium aduncum commonly occurs in many fish species the Northeast (NE) Atlantic. parasite is considered non-pathogenic to humans. During spring and summer of 2018, lots head-on eviscerated fresh NE Arctic cod (Gadus morhua) were shipped from Norway Spain for commercialization. At arrival, presence lively roundworms (i.e. H. aduncum) transporting boxes was notice...

In rural African communities, there are widespread beliefs that epilepsy is due to possession of bewitchment by evil spirits or the devil. There is also a belief that the transmis­ sion of the disease is by physical contact, such as by sa­ liva (Osuntokun 1990:106). In central Africa, as well as in Sub-Saharan Africa, epilepsy is attributed to the presence of a lizard in the brain, and epilepti...

Tyrosine phenol-lyase was purified 32-fold from Aeromonas phenologenes ATCC 29063, the organism that produces phenol in refrigerated haddock. The purification procedure included ammonium sulfate fractionation, protamine sulfate treatment, and column chromatography with Sephadex G-200, diethyl-aminoethyl-cellulose, and hydroxyapatite. The enzyme was found to be thermally inactivated at temperatu...

Predator–prey interactions play an influential role in determining the demographics of a population or species. In the Northwest Atlantic, Atlantic cod, Gadus morhua, once the basis of a lucrative commercial fishery, have not recovered despite regulations imposed on the fishery to reduce harvest rates. One possible reason for the lack of recovery is that high predation pressure on juvenile and ...

Three studies offer novel evidence addressing the consequences of explicit–implicit sexual orientation (SO) ambivalence. In Study 1, self-identified straight females completed explicit and implicit measures of SO. The results revealed that participants with greater SO ambivalence took longer responding to explicit questions about their sexual preferences, an effect moderated by the direction of...

quota in the Kattegat region between Sweden and Denmark, the Irish Sea and the west of Scotland. Environmental groups have long called for the industry to adopt new technologies and practices that can substantially reduce 'bycatch'. Larger mesh size is one straightforward measure that can save more juvenile fish. Charles Clover, author of The End Of The Line, said: " It is ridiculous that we ca...
