background and objectives: pseudomonas aeruginosa is one of the most important opportunistic pathogens in patients who suffer from immunodeficiency and burns. wound infections caused by p. aeruginosa can rapidly change to systemic and life threatening situation. the aim of this study was to apply florescent in situ hybridization (fish) method for rapid detection of p. aeruginosa in burrn patien...

Environmental DNA (eDNA) promises to ease noninvasive quantification of fish biomass or abundance, but its integration within conservation and fisheries management is currently limited by a lack of understanding of the influence of eDNA collection method and environmental conditions on eDNA concentrations in water samples. Water temperature is known to influence the metabolism of fish and conse...

in aquaculture, fishes might experience periods of food deprivation during pre-harvesting, transporting and sorting. in during starvation, some fish utilize muscle protein as a major energy source and some fish utilize primarily lipids. with respect to vital role of starvation periods on body composition, the current study was carried out for one month in autumn 2010 at research farm of isfahan...

total petroleum hydrocarbon ( tph ) are environmental contaminants that are released into the marine environment through oil spills, industrial and domestic activities. tph are readily transformed into more hydrophilic metabolites, which are accumulated in bile. thus fish bile can be used as a biomarker of exposure of fish to tph in the marine environment. in this study several stations were se...

A convenient method for chemically treating zebrafish is to introduce the reagent into the tank water, where it will be taken up by the fish. However, this method makes it difficult to know how much reagent is absorbed or taken up per fish. Some experimental questions, particularly those related to metabolic studies, may be better addressed by delivering a defined quantity to each fish, based o...

Background:Breast cancer remains the most common and second lethal cancer in females. HER-2/neu is one of the most important amplified oncogene in breast cancer. The amplification of HER-2 is correlated with decreased survival, metastasis, and early recurrence.  The amplification of HER-2/neu gene and synthesis of th...

Fish sauce is a fermented product which is used in south Asian countries. In the present study, Caspian Kilka was used to produce the sauce, using either cooked or raw fish subjected to four different treatments: 1) traditional method, where fish and salt were used; 2) an enzymatic method, where fish, salt and proteolytic enzymes, including Protamex and Flavourzyme (Novo Nordisc Co., Bagsvaerd,...

in this investigation, the mercury content of different samples of persian gulf shrimp and fish, caspian sea fish and the samples of fish from bandar pahlavi lagoon, zarjoub river near rasht, zayandehroud river near esfahan, and karadj river near tehran were measured by flameless atomic absorption, cold vapor-technique, using standard addition method. the main purpose of this study was to inves...

A new semi-quantitative analytical method for mercury determination in gold prospecting areas, and 16 new local users, 5 in Itaituba-Brazil and 11 in ManadoIndonesia, were trained for using it as an alternative and low cost method for mercury determination in fish in August and September 2003. This experience demonstrated the spreading potential throughout those areas of such low-cost method an...
