We studied nine solid and two liquid media for their suitability to select Aeromonas and Plesiomonas spp. from human stools, using artificially contaminated samples as well as 254 samples from outpatients with and without diarrhea. Media with optimal sensitivity and specificity for Aeromonas spp. were alkaline peptone-water, Trypticase soy broth with ampicillin, inositol-brilliant green-bile sa...

Dunaliella salina is a unicellular green microalga that is considered as one of the best commercial sources of carotenoids. Growth and pigment production of D. salina (isolated from Sambhar Salt Lake, Rajasthan) was studied by using various inorganic media differing in chemical compositions viz. Artificial Sea Water media, De Walne’s media, Johnson’s media, AS-100 and Modified Bold’s Basal medi...

Green roofs can mitigate urban rooftop stormwater runoff. However, the lack of accurate, physically-based performance assessment and design models has hindered their wide application. Most hydrologic or hydraulic models have no direct connection to the physical properties of green roof components such as media type/depth, drainage depth, etc. In an effort to assist design engineers, a simplifie...

Many best-management practices (BMPs) currently used in urban regions have been developed to minimize flood risk, sustain downstream ecosystems, and secure the quality of groundwater sources either directly or indirectly. One such BMP is the reuse of stormwater by removing nutrients from the nutrient-laden “first flush” water collected in wet or dry ponds; this practice has led to the developme...

a green and convenient méthode for the synthesis of  a variety of xanthene derivatives by condensation reaction between aldehydes and β-naphthol or dimedone in an micellar solution of sodium dodecylphosphonate is described. this method offers several advantages, such as using of a cheap and environmentally benign reaction media, low loadings of sodium dodecylphosphonate as catalyst and easy wor...

silica gel has been used for synthesis of biscoumarin derivatives starting from 4-hydroxycoumarin and aryl aldehydes. the reaction conditions are completely in agreement with green chemistry principles including sing water as media and a recyclable and safe catalyst. this method is also simple and inexpensive and leads to high yield of products in short reaction times.

objective: dental caries is a common infectious disease. streptococcus mutans is the prevalent decay microorganism. the anti streptococcus mutans activity of non fermented and semi-fermented tea has been shown. the aim of this study was to determine the anti streptococcus mutans activity of iranian green and black tea (non fermented and fermented type). materials and methods: the study was expe...

E-mail: [email protected] Radiological procedures using injection of contrast media have been employed increasingly for diagnostic purposes (1). Nevertheless, side effect of contrast media injection known as contrast media nephrotoxicity is still a major c...
