Using histological and biochemical methods, ovaries of the Barents Sea cod Gadus morhua were studied in different physiological states (immature fish, normal maturation, omission of spawning). Among the fish missing spawning, two categories are identified: without signs of occyte maturation and with massive resorption of maturing oocytes. The maximal(More)
The Greenland halibut Reinhardtius hippoglos soides is widespread in the North Atlantic and in the adjacent sector of the Arctic Ocean. This valuable commercial species reaches 120 cm in length and more than 20 kg in weight (Kovtsova and Nizovtsev, 1985). The Norwegian Barents Sea population (Northeast Arctic Greenland halibut) inhabits the Barents Sea and(More)
Coenzyme A disulfide (CoA disulfide) was pharmacologically studied. It has been found to normalize lipid and carbohydrate metabolism when given in a dose of 2 mg/kg, i.m., in diverse liver dysfunctions. It possesses an antihypoxic action under hemic and histotoxic hypoxia. When given in small doses (80-160 micrograms/kg, i.v.), CoA disulfide depresses the(More)
A new type of coating for manufacturing DNA chips was constructed on the basis of an organicinorganic nanocomposite based on the polyvinylbutyral-tetraethoxysilane copolymer. The organosilicon composite was functionalized by introduction of ethanolamine vinyl ether copolymers, which contain amino groups and anchor vinyloxide units capable of reacting with(More)
The reproductive status of some categories of females of the beaked redfish Sebastes mentella has been determined as a result of the histological analysis. The histological characteristic of gonads of large nonreproductive females of redfish is presented for the first time. Gonads of mature females that skip spawning are studied. The cytomorphological(More)
The problem of the structure of the population of the Northern Arctic Cod Gadus morhua is the subject of active discussions and has not received an unambiguous assessment up to now (Borisov et al., 1999; Berg and Albert, 2003). For revealing the extent of isolation of the groups of cod and elucidating their status, different methods are used: morphometric,(More)
