In this work, different lignins were obtained from two extraction methods (kraft and organosolv) but the same raw material (Eucalyptus globulus sp.). They subsequently fractionated to determine differences of each method their corresponding physicochemical properties found in fractionation sequence fractions. The goal was obtain lignin fractions with narrower molecular weight distribution lower...

BACKGROUND Hypo-fractionated external beam radiotherapy with narrow CTV-PTV margins is increasingly applied for prostate cancer. This demands a precise target definition and knowledge on target location and extension during treatment. It is unclear how increase in fraction size affects changes in prostate volume during treatment. Our aim was to study prostate volume changes during extreme hypo-...

Extraction of cellulose and hemicellulose from natural resources has attracted considerable interest. In comparison to other cereals, there is relatively little knowledge on the cellulose, lignin content sorghum by-products. As such, aims this study were develop a multi-step process for by-products (bran, stalk panicles) fractionation characterise them with regards their physicochemical propert...

the optimal fractionation schedule for radiotherapy of head and neck cancer has been controversial. the objective of this randomized trial was to test the efficacy of hyperfractionation vs. standard fractionation. patients with squamous cell carcinoma of head and neck organs were randomly assigned to receive radiotherapy delivered with a) standard fractionation at 2 gy/fraction/day, 5 days/week...

background: plasminogen is one of the compounds derived from human plasma. activation of plasminogen produces plasmin. plasmin is able to lyse fibrinogen, fibrin, and some other human plasma proteins. the aim of the present work was to study the separation of human plasminogen by affinity chromatography using gel lysine sepharose. materials and methods: normal human plasma was used as the start...
