Kilka fish are known as the main industrial and pelagic species of Iran that are captured abundantly in the southern Caspian Sea. This study was conducted to survey the effectiveness of refinement steps on Kilka (Clupeonella delicatula) crude oil quality and fatty acid profiles. Neutralization, bleaching, winterization and deodorization were performed on crude oil with deodorization done under ...

background and objectives: this paper describes chemical composition and antimicrobial activity of cymbopogon nardus citronella essential oil against edwardsiella spp. (n = 21), vibrio spp. (n = 6), aeromonas spp. (n = 2), escherichia coli (n = 2), salmonella spp. (n = 2), flavobacterium spp. (n = 1), pseudomonas spp. (n = 1) and streptococcus spp. (n = 1) isolated from internal organs of aquat...

Soil nutrients are vital for plant growth and survival present a crucial role in terrestrial function productivity. However, little is known about the effect mechanism of groundwater table on soil an arid desert ecological system. This study investigated impacts depth concentrations organic carbon (C), available nitrogen (N), phosphorus (P), potassium (K) at shallow depths (0.4, 0.8, 1.2, 1.8, ...

background: imatinib mesylate, a small-molecular analog of adenosine triphosphate (atp) that potently inhibits tyrosine kinase activities of bcr–abl, pdgfr-β, pdgfr-α, c-fms, arg and c-kit, is one of the novel molecularly targeted drugs being introduced into cancer therapy. we tested the effect of imatinib on the ovarian histological structure and the concentration of estrogen and progesterone,...

conclusions in this study, snpcr was specific and more sensitive than the chromogenic medium chromagar™ candida for the detection of candida spp. insofar as it failed to identify only a few isolates. materials and methods we used snpcr with universal and species-specific primers to detect candida species in the culture of clinical isolates. by using universal primers, we carried out the amplifi...

Micelles formed in water from ammonium dodecyl sulfate (AmDS) are characterized using time-resolved fluorescence quenching (TRFQ), electron paramagnetic resonance (EPR), conductivity, Krafft temperature, and density measurements. TRFQ was used to measure the aggregation number, N, and the quenching rate constant of pyrene by dodecylpyridinium chloride, k(Q). N depends only on the concentration ...
