background: the purpose of this study was to perform seroepidemiological investigation for determining the status of human fasciolosis in pirabad village, lorestan province, western iran. methods: blood samples were taken from residents of the village including 801 individuals. sera were separated and stored at -20°c until used. the samples were analyzed using elisa. results: anti- fasciola ant...

The potential ecological impacts of anaerobic degradation of vegetable oil on freshwater sediments were investigated. Sediment toxicity was evaluated using two regulatory biotests: the Microtox Solid Phase Test and an amphipod (Hyalella azteca) bioassay. The results of the Microtox test showed that the toxicity of the vegetable-oil-contaminated sediments (about 17–33 g oil/kg dry sediments) inc...

Freshwater prawn farming has become an important component in the livelihood of marginal farmers freshwater interface Southwestern coastal Bangladesh. This been integrated with rice and/or vegetable either simultaneously or sequentially. In attempt to assess status prawn-agriculture gher area, 20 farms at Fakirhat Thana, Bagerhat were surveyed during August-October, 2005. Farmers interviewed qu...

there are many freshwater snails involved in the life cycle of parasitic flukes. some of these animals, such as bulinus spp and lymnaea spp are very important in public health and veterinary medicine. for example, bulinus trucatus and lymnaeid snails transmit human bilharziosis and zoonotic fascioliosis, respectively. for this reason most freshwater bodies of northern iran, were searched for po...

Trigger-inducible transcription-control devices that reversibly fine-tune transgene expression in response to molecular cues have significantly advanced the rational reprogramming of mammalian cells. When designed for use in future gene- and cell-based therapies the trigger molecules have to be carefully chosen in order to provide maximum specificity, minimal side-effects and optimal pharmacoki...

Vegetable oils (VO) have become the predominant substitute for fish oil (FO) in aquafeeds; however, the resultant lower content of n-3 long-chain ( ≥ C20) PUFA (n-3 LC-PUFA) in fish has put their use under scrutiny. The need to investigate new oil sources exists. The present study tested the hypothesis that in Atlantic salmon (Salmo salar L.), a high intake of stearidonic acid (SDA) from Echium...

this paper presents a total of 11 known crustacean parasite species from 51 host species belonging to 7 families, with 17 genera reported from cultured and wild fishes in three faunal regions of iran. among them, one belonging to branchiura order, namely argulus foliaceus, was found on capoeta capoeta in makoo reservoir as well as on cyprinus carpio, chalcalburnus sp., hypophthalmichthys molitr...

this study was conducted to determine taxonomic feature of fishes from the headwaters of three riverine systems in kohgiluyeh and boyer-ahmad province (k & b) in southwestern iran during 2011 to 2013. fifteen species belonging to 4 families, and 3 orders from the karun river system, 10 species belonging to 4 families and 3 orders from the zohreh river system and 8 species belonging to 2 fam...
