The relative stabilities of specific embryonic mRNAs that persist in Drosophila melanogaster larvae were determined using an approach that combined RNA density labeling with cell-free translation. Unlike the other methods commonly used to measure the decay of individual mRNAs, the density labeling approach does not depend on the use of transcriptional inhibitors or on the measurement of precurs...

Field populations of aquatic organisms, particularly those inhabiting flowing waters, likely are exposed to short pulses of pesticides following periods of spray drift, surface runoff, or drain flow. In the present study, we investigated the effect of pulse exposures of a pyrethroid insecticide, esfenvalerate, on survival, development, and reproduction of the midge, Chironomus riparius. The fir...

Culex pipiens mosquito is a species widely spread across Europe and represents a competent vector for many arboviruses such as West Nile virus (WNV), which has been recently circulating in many European countries, causing hundreds of human cases. In order to identify the main determinants of the high heterogeneity in Cx. pipiens abundance observed in Piedmont region (Northwestern Italy) among d...

The impact of young-of-the-year (YOY) fish predation on zooplankton dynamics and cascading effects down to phytoplankton were studied in lake enclosures using different densities of larval and juvenile European perch (Perca fluviatilis). Two experiments, one in June and one in August, were performed in Lake Dagstorpssjön, a slightly eutrophic lake in Scania, southern Sweden. In our experiments,...

Galectin-1 and superoxide dismutase are two known molecules in the wound healing process that induce such healing by different mechanisms in the wound site. Larval therapy is one of the methods use by Lucilia sericata fly larvae, nowadays returned to the list of therapeutic methods despite chronic diabetic ulcers and antibiotic resistance of bacteria. In this study, we aimed to evaluat...

the main objective of the present study was investigation on influences of different brackish water sources on freshwater prawn larval quality and developmental indices. for this study, along a larval period, four brackish water treatments with 12 ppt salinity including diluted marine water, brackish water from marine crystalline salt, brackish water with compounds of new formula and brackish w...
