Silymarin is a mixture of flavonolignans from the seeds of Silybum marianum (L.) Gaertner,containing silybinin, isosilybinin, silydianin, silychristin and the dihydroflavonol of taxifolin. Flavonolignancomponents are largely ...

Cyanobacteria were collected and identified in five paddy fields with different soil textures of Golestan province in Iran. It was determined that Nostoc ellipsosporum and Nostoc muscorum were dominant in all sites among ...

The thermal denaturation of α-Amylase from Bacillus amyloliquefaciens has been investigated in the presence and absence of sodium dodecyl sulphate (SDS) over the temperature range (293-373) K in 20 mM sodium phosphate ...

Air pollutants are reported to increase the specific IgE response to allergens. To study allergen proteins and determine the effect of air pollutants on the allergenic potential of pollen extracts, the extracts were injected ...

Phosphatidate phosphohydrolase (PAP2b, fraction b) was purified from the plasma membrane ofrat liver cells. The Km for the surface concentration of phosphatidic acid was 0.43 mol%. The subunit of theenzyme had an M.W. of ...

Soil productivity is generally associated with poor nutrient status and the physical condition of the soil, but the effect of soil mineralogy on soil productivity has received little attention. In this qualitative study, ...

Organotypic spinal cord slices from neonatal mammals could be a powerful model for evaluation of cell survival but also cell death mechanisms. The aim of this study was to establish an in vitro model for investigating cell ...

Pollen morphology of some species of the genus Malus (Rosaceae) was investigatedtaxonomically. All species are characteristic by tricolpate pollens. Exine sculpturing is variable but is mostlystriate. However, species may ...
