A screen was recently developed to study the mobilization of starch in the unicellular green alga Chlamydomonas reinhardtii. This screen relies on starch synthesis accumulation during nitrogen starvation followed by the supply of nitrogen and the switch to darkness. Hence multiple regulatory networks including those of nutrient starvation, cell cycle control and light to dark transitions are li...

OBJECTIVES Hydroxyethyl starch 200 is associated with renal impairment in sepsis, but hydroxyethyl starch 130/0.4 and gelatin are considered to be less harmful. We hypothesized that fluid therapy with only crystalloids would decrease the incidence of acute kidney injury. DESIGN Prospective sequential comparison during intensive care unit stay. SETTING Surgical intensive care unit. PATIENT...

Mango suffers from numerous diseases throughout its life due to fungal growth. Primarily, mango is infected with anthracnose, a disease caused by Collectotrichum gloeosporioides. In the present study, fruits were coated zinc oxide (ZnO) and tapioca starch solution at different concentrations stored room temperature for week. The growth of any black spots on outer surface fruit peel was observed...

In order to determine by viscometric methods (l), the effect of the hydrogen ion concentration of starch substrates upon the activity of the amylase of Aspergillus oryxa! (taka-diastase), it was first necessary to ascertain the effect of acid and alkali alone upon the viscosity of starch solutions. E$ect of Hydrogen Ion Concentration upon the Viscosity of Unbu$ered Starch Solutions.-10.2 gm. of...

Starches extracted from wrinkled (WP) and smooth (SP) peas were treated using β-amylase (B) alone and also with a combination of β-amylase and transglucosidase (BT). After enzymatic treatment, the proportions of slowly digested starch in WP-B, WP-BT, SP-B and SP-BT samples were increased by 6%, 9%, 9% and 12%, respectively. Starches treated by a combination of β-amylase and transglucosidase exh...

Bile acid sequestrants (BAS) represent a therapeutic approach for the management of hypercholesterolemia that relies on the cationic polymeric nature of BAS to selectively bind negatively charged bile acids. We hypothesized that the cross-linking of β-cyclodextrin (β-CD) and saccharides such as starch or dextrin with divinyl sulfone (DVS) yields homo- and hetero-polymeric materials with the abi...

Activated carbons were investigated for their heat catalytic effects to improve saccharification of starch by autohydrolysis in water under microwave electromagnetic field, and the results were compared with graphite and carbon nanotubes. The activated carbons with low adsorptive capacity of maltose showed high saccharification rate, while those with high adsorptive capacity exhibited low sacch...

the aim of this study was to design orally disintegrating tablets of olanzapine and to complex olanzapine with 2-hydroxypropyl-β- cyclodextrin with special emphasis on disintegration and dissolution studies. phase solubility studies demonstrated the formation of 1:1 molar inclusion complex by kneading method. tablets were prepared by using superdisintegrants namely, sodium starch glycolate, cro...

To better understand the mechanisms involved in the heavy metal stress response and tolerance in plants, a proteomic approach was used to investigate the differences in Cu-binding protein expression in Cu-tolerant and Cu-sensitive rice varieties. Cu-binding proteins from Cu-treated rice roots were separated using a new IMAC method in which an IDA-sepharose column was applied prior to the Cu-IMA...

The aim of this study was to investigate the role of the plant food matrix in influencing the extent of starch gelatinisation during hydrothermal processing, and its implications for starch digestibility. Differential scanning calorimetry (DSC) was used to provide a detailed examination of the gelatinisation behaviour of five distinct size fractions (diameters <0.21 to 2.58 mm) of milled chickp...
