High frequency stimulation (HFS) (130 Hz) of the subthalamic nucleus (STN) provides beneficial effects in patients suffering from severe parkinsonism, but the mechanisms underlying these clinical results remain to be clarified. To date, very little is known concerning the effects of STN-HFS on neurochemical transmission in the different basal ganglia nuclei and in particular the striatum. This ...

A compilation of 38 sequences for the D1 and 15 sequences for the D2 reaction center proteins of photosystem II is presented. The sequences have been compared and a similarity index that takes into account the degree of conservation and the quality of the changes in each position has been calculated. The similarity index is used to identify and describe functionally important domains in the D1/...

arthrobotrysamerospora (atcc 34468) produced glucoamylase in a semi-synthetic medium containing starch as a sole carbon source. polyacrylamide gel electrophoresis of crude glucoamylase showed three isoenzymes. they were designated as glu i, glu ii and glu iii according to their electrophoretic mobility. these iso-glucoamylases were purified by column chromatography using deae-sephadex a-50. the...

in this study the effects of water salinity on serum total protein and its components in grass carp were investigated. the aim of this study was to determine the effect of salinity tolerance of fish on total serum protein level and its components as an indicator of liver and kidney activity. one hundred and twenty grass carp were divided into four groups, randomly. the first three groups were r...

Spring durum wheat is an important raw material for producing diverse products such as couscous, bulgur, bread, and pasta. The quality of the dough significantly influenced by high-molecular-weight glutenins, allelic status which depends on region breeding program. In this study, a collection 69 cultivars promising lines were analyzed state Glu-A1 Glu-B1 using SDS-PAGE KASP PCR markers. Protein...
