serious concerns have been expressed about potential health risks of nano silver containing consumer products (agnps) therefore regulatory health risk assessment on such nanoparticles has become mandatory for the safe use of agnpsinbiomedicalproducts with special concerns to the mutagenic potentials. in this study, we examined the inhibitory and mutagenicity effects of agnps in three different ...

shampoos are products which remove surface grease and dirt from the hair shaft and scalp. the cleansing or detergent action of a shampoo is a primary function. however, the foaming characteristic of a shampoo has an important role in its acceptability. often alkanolamides are used for the formation of a stable foam; but because of producing nitrosamines, they are potentially carcinogenic compou...

ethylammonium propionate with high polarity and ionic conductivity was synthesized andcharacterized with 1hnmr and ir. this ionic liquid which is prepared from readily available startingmaterial in high yield shows reasonably high at viscosity and heat stability up to 150 °c. this ionicliquid is able to dissolve most of organic solvents due to the hydrogen interaction between ionicliquid and th...

abstract         background and objective: lactic acid bacteria are gram-positive, catalase-negative, nonsporulating, either rod- or coccus-shaped bacteria that have beneficial effects on their hosts by producing antimicrobial substances such as lactic acid, hydrogen peroxide, bacteriocins and biosurfactants. bacteriocins are antimicrobial peptides that are produced by bacteria and can inhibit ...

To clarify the differences between commercially available compounds, clinical candidates, and launched drugs with regard to distribution of physicochemical properties and to characterize the correlation between physicochemical properties, we conducted analyses on physicochemical descriptors of commercially available compounds, clinical candidates, and launched drugs. Initial analysis of the mar...

BACKGROUND Mosquitoes lay eggs in a wide range of habitats with different physicochemical parameters. Ecological data, including physicochemical factors of oviposition sites, play an important role in integrated vector management. Those data help the managers to make the best decision in controlling the aquatic stages of vectors especially using source reduction. METHODS To study some physico...

grain quality currently represents a major problem in high yielding rice production in iran and many other rice producing areas of the world. quality assessment of rice involves the function of sensory tests and physicochemical determinations based on the chemical composition, cooking quality, gelatinization temperature and physical properties of cooked rice. these research genetic materials we...

abstract soil crust decreases soil infiltration and prevents plant stablishment. thus reduction of crust effects is a prominent way to avert desertification. this study was conducted to investigate the effect of polyacrylamide on emergence of canola seedlings in a crusted soil and some physicochemical properties of soil such as ph, ec, sar and bulk density in a field located in date and tropica...

this study was intended to evaluate the quality of 30 honey samples, in terms of physicochemical properties such as moisture content, electrical conductivity, ash content, reducing sugars and sucrose, free acidity, ph, diastase activity, and hydroxymethylfurfural (hmf) content. moreover, three methods recommended by the international honey commission for the determination of hmf, including 1) h...

background: the prangos ferulacea (pf)–yogurt is a traditional food in iran. this study investigated the effects of pf on the microbial, physicochemical and sensory properties of probiotic yoghurt. methods: pasteurized low fat milk was heated up to 85°c, cooled to 40°c, and then mixed with conventional and lactobacillus casei starter cultures incubated at 37°c until ph decreased to 4.6. then, t...
