background: the present study was carried out to detect the infection of larval stages of trichobilharzia species in the snail lymnaea auricularia in northwestern iran based on dna analysis. methods: a total number of 320 snails of l. auricularia were sampled from four water-bodies located in the suburb of urmia city, north west iran, during may to november 2011. the snails were first microscop...

We studied the efficacy of water-soluble extracts from four Ajuga spp on the post-embryonic development of two exopterygota (sucking insect) species. To allow comparison between different Ajuga species, results are expressed in terms of quantity of plant extracted per litre of test solution. Crude methanolic extracts of all Ajuga plants tested, with the exception of A genevensis, showed conside...

The lasing characteristics of InP-based InAs/In 0.53 Ga 0.47 As quantum well (QW) lasers with different ridge widths are investigated. Two groups grown for comparison, one active triangular QW regions and the other rectangular regions. Their output powers, characteristic temperatures ( T 0 ), external differential efficiencies η d ) junction j analyzed compared. parameter width is found to play...

Prostate cancer (PCa) is a leading cause of mortality and morbidity in men worldwide, and emerging evidence suggests that the CD44high prostate tumor-initiating cells (TICs) are associated with its poor prognosis. Although microRNAs are frequently dysregulated in human cancers, the influence of microRNAs on PCa malignancy and whether targeting TIC-associated microRNAs inhibit PCa progression re...

there are many remediating methods for the polluted soils but only phytoremediation is a cost effective, environmental friendly, aesthetically pleasing approach that is most suitable for many countries. the purpose of this study was to investigate the potential of native plants for phytoremediation of contaminated soils with lead, zinc, cadmium and nickel in the rangelands around national lead ...

environmental pollution with heavy metals is a global disaster that is related tohuman activities. this study was conducted to determine the extent of heavy metalsaccumulation by plant species in lia industrial city (qazvin, iran) and to investigate theremediative capacity of native plant species grown in the contaminated soils. soil andindustrial wastewater sampling was done radially along tra...

miRNAs play an important role in several biological processes. Here, we investigated miR-320 in glucose-induced augmented production of vasoactive factors and extracellular matrix (ECM) proteins. High glucose exposure decreased the expression of microRNA 320 (miR-320) but increased the expression of endothelin 1 (ET-1), vascular endothelial growth factor (VEGF), and fibronectin (FN) in human um...
