background: mercury is a heavy metal with high toxic effects. it has many apply to various industries, so can enter to the environment from different resources. therefore, its elimination from wastewater is a major challenge. in this study, removal of mercury from aqueous solution using two types of almond shell was investigated and compared. methods: this experimental-intervention study has be...

The grass sharpshooter, Draeculacephala minerva Ball (Hemiptera: Cicadellidae), is a very common and often abundant grass-feeding leafhopper in California. Its population dynamics and ability to transmit Xylella fastidiosa were monitored over a 2-yr period in California's San Joaquin Valley. Collections of individuals from natural populations in irrigated pastures and alfalfa, Medicago savita L...

Buffer type, pH and ionic strength, as well as the fraction of polyvinylpyrrolidone were optimized for efficient extraction of b-galactosidase from almond seeds. The enzyme was purified up to electrophoretic homogeneity employing (NH4)2SO4 (15–60 %) fractionation, size exclusion and ion-exchange chromatography. Molecular mass of b-galactosidase as estimated by gel filtration and SDS-PAGE was ap...

background: osteoarthritis is one of the most common diseases in middle‑aged populations in the world and could become the fourth principal cause of disability by the year 2020. one of the critical properties for cartilage tissue engineering (te) is the ability of scaffolds to closely mimic the extracellular matrix and bond to the host tissue. therefore, te has been presented as a technique to ...
