background: measurement of gross , gross activities, and cosmogenic beryllium-7 (7be) concentrations were made both daily and weekly during the years 2001- 2004 from samples of atmospheric aerosols filtered from the air at tehran nuclear research center (35 41' n) and zahedan (28 29' n). materials and methods: weekly aerosol samples were collected with the high-volume air samplers on ...

the aim of this study was to characterize albumin fractions of four different wheat varieties grown in a local climatic context, as well as to find the relationship between the particular albumin fractions and enzyme activity of the tested wheat flours and dough rheological properties. the determined content of albumin fractions ranged from 2.64 to 17.50% of total proteins. more than 50% of the...

the in vitro antioxidant and antimicrobial activities of the essential oil and methanolic extract of achillea sieheana staf. (asteraceae) were investigated in this study. the chemical composition of the essential oil isolated by hydro-distillation from the aerial parts of a. sieheana was analyzed by gc–ms. camphor (43.36%), artemisia ketone (25.95%), 1.8-cineole (6.29%) and camphene (4.77%) wer...

different solvent extracts of a red algae, hypnea flagelliformis,and two brown algae, cystoseira myrica and sargassum boveanum, collected from the persian gulf coast were subjected to different bioassays including: 1,1-diphenyl-2-picrylhydrazyl (dpph) free radical scavenging assay, antibacterial and antifungal activity by thin layer chromatography (tlc)-bioautography, agar disc diffusion (add) ...

methanol 70% extract of bauhinia racemosa aerial parts was tested for antimicrobial activity against different bacterial and fungal strains and for antioxidant activity and also total content of polyphenols with phytochemical analysis of the extract was determined. the results have showed that the extract has a significant antimicrobial activity, it inhibited the growth of bacillus subtilis and...

background and objectives: application of garlic oil in food industry can be improved by encapsulation. there is no study about the formation of inclusion complex of garlic oil by beta-cyclodextrin. the aim of the present study is comparison of the antioxidant and antibacterial activities of free and encapsulated garlic oil with beta-cyclodextrin. materials and methods: antioxidant activity was...

background and objectives: dermatophytes possess a wide array of virulence factors and various antifungal susceptibility patterns which influence their pathogenesis in humans and animals. the aim of this study was to evaluate antifungal suscep- tibility and keratinase and proteinase activity of 49 dermatophyte strains from the genera microsporum , trichophyton and epidermophyton which were isol...

objective(s) as an important class of natural products, coumarins exhibit many biological activities and the diversity of their bioactivity is so huge that the pharmacological promiscuity has been applied on their case. oxypeucedanine also named as prangolarin is a linear furanocoumarin with an oxygenated prenylated substitution at c-5 of the nucleus. to our knowledge, there are few reports on ...
