Abstract

Production of renewable and modified starch-based products was achieved using a sustainable catalyst an environmentally friendly drying process via supercritical CO2. Potato starch green esterification with acetic anhydride reagent implementing novel organocatalytic pathway at different periods time (0.5, 3 7 h) by applying reaction 120°C targeting intermediate degrees substitution (i.e., 0.2 <...

T’ HE ECONOMICAL MANAGEMENT of a hospital laboratory requires the gradual replacement of manual by mechanical manipulations. Fully automatic devices are now available for serial determinations on blood arid other biologic fluids, but their use is sometimes limited by financial and space considerations, even to the big laboratories performing some hundred or more analyses of the same type every ...

The aim of this paper is to present the structure of a class of matrices that enables explicit inverse to be obtained. Starting from an already known class of matrices, we construct a Hadamard product that derives the class under consideration. The latter are defined by 4n − 2 parameters, analytic expressions of which provide the elements of the lower Hessenberg form inverse. Recursion formulae...

Reagents. Thioglycolic acid (TGA), Bovine serum albumin (BSA), imidazole, N-(3dimethylaminopropyl)-N’-ethyl-carbodiimide hydrochloride (EDC), Nhydroxysuccinimide (NHS), (+)-Biotin N-hydroxysuccinimide were purchased from Sigma-Aldrich. EDC and NHS were dissolved in water immediately before use. Human prostate-specific antigen (PSA), two mouse antihuman total PSA monoclonal antibodies (primary c...

In the present work, all steps of the sulfate reduction procedures, such as reduction, distillation and sulfate determination were joined in only one FIA system. The formed sulfide was on-line determined by employ the Fisher reaction. The proposed method presented a LOD of 1.00 μg L(-1) and a LOQ of 3.33 μg L(-1), well lower than the most commonly used turbidimetric determination, with no signi...

The low protein barley (Hordeum vulgare L.) cultivar ;Karl' is deficient in hordeins, the major storage protein fraction, but has normal levels of other endosperm protein fractions. We compared hordein gene expression in Karl with that in ;Traill,' a related cultivar that contains normal amounts of hordein. In plants grown in controlled environmental conditions, hordein accumulation in Karl was...

BACKGROUND The commonly recommended therapeutic range for patients receiving unfractionated heparin of 1.5 to 2.5 times the control activated partial thromboplastin time (aPTT) is not universally applicable. It has been suggested that the therapeutic range for each aPTT reagent should be based on plasma heparin levels. We sought to identify an aPTT ratio that corresponds to therapeutic anti--fa...

Experimental section General All chemicals and solvents for peptide synthesis were of reagent or HPLC grade and were used without further purification. TARON resin was purchased from Clontech. Dihydrofolate (DHP), nicotinamide adenine dinucleotide phosphate (NADPH) and methotrexate (MTX) were purchased from Wako Pure Chemical Industries. Biotin-AC5-OSu and 2-morpholinoethanesulfonic acid monohy...
