Low insecticide exposure has been shown to cause profound effects on non-target organisms, including crabs. Therefore, the changes in hematological parameters, serum biochemistry and antioxidant enzymes Gercacinid crab, Cardiosoma armatum were assessed during 28-day four concentrations of organophosphate chlorpyrifos (0.003, 0.006, 0.03 0.06 mg/l). The results showed a significant (P= 0.0) decr...
there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
fast development of aquaculture and increasing fish demand lead to intensification of fish culture, magnifying stressors for fish and thus heightening the risk of disease until now, chemotherapy has been widely used to prevent and treat disease outbreaks, although use of chemical drugs has multiple negative impacts on environment and human health e.g. resistant bacterial strains and residual ac...
Background: Deoxynivalenol (DON) and zearalenone (ZEN) are common food contaminants produced by Fusarium sp. Mycotoxins are a potential health hazard because of their toxicological effects on both humans and farmed animals. Methods: We analyzed three groups of pigs: a control group (fed a standard diet), and the DON and ZEN groups, fed a diet containing 8 mg/kg DON and 0.8 mg/kg ZEN respectivel...
background: the present study deals with the effect of helminthic infection as nematode parasite like aspiculuris tetraptera on the haematological parameters of infected and vaccinated mice. methods: totally 15 mice were used. five mice were used for positive control, 5 mice used for negative control and 5 mice used for experiment. the hematological parameters were studied viz. rbc, hb, and se...
