Optic chiasm lesions in myelin oligodendrocyte glycoprotein (MOG)-experimental autoimmune encephalomyelitis (EAE) mice were characterized using magnetic resonance imaging (MRI) and validated using electron microscopy (EM). MR images were collected from 3 days after induction to remission, approximately 20 days after induction. Hematoxylin and eosin, solochrome cyanin-stained sections, and EM im...

Phytochemicals represent a rich resource for the discovery of novel pesticides that are effective, cheap and environmentally safe. The main targeted mosquito vectors Aedes aegypti and Anopheles stephensi cause serious human diseases. The chloroform, acetone, ethanol, methanol and aqueous peel extracts of Arachis hypogaea were studied for its larvicidal activity against the mosquito vectors. Phy...

The phenomenon of copigmentation is due to molecular associations between pigments and other (usually noncolored) organic molecules in solution. These associations cause the pigments to exhibit far greater color than would be expected from their concentration. The phenomenon has long been recognized in flowers and fruits. Willstatter and Zollinger [122,123] noted the intensification of color on...

The present investigation depicts the development of a simple and low cost method for the removal of color from textile dyeing and printing wastewater using ZnO as photocatalyst supported with porous activated carbon (AC). Photocatalytic degradation studies were carried out for water soluble toxic alizarin cyanin green (ACG) dye in aqueous suspension along with activated carbon (AC) as co-adsor...

The copper containing oxygen carrier haemo­ cyanin is the predominant protein in the hemolymph of most molluscs, crustaceans and spiders. Despite its abundance and the detailed knowledge on physiological aspects, relatively little informa­ tion exists on haemocyanin synthesis and its regu­ lation [1-4], In analogy to haemoglobin, where the addition of haeme influences the haemoglobin production...

Data are presented which indicate that dimethylsulfoxide (DMSO) acts selectively on the plasma membrane of cultured tobacco cells, rendering it more permeable to small molecules, while having a far smaller effect on the permeability of the vacuolar membrane. The results which support this conclusion are: (a) DMSO (5 to 10%, by volume) causes complete release of [(14)C]tryptophan newly synthesiz...

The protein of milk residue can be quanti tated to evaluate a cleaning process by monitoring the accumulation of protein in a test-wash solution. The test for protein is based on precipitat ion of hard water cations with or thophosphate and flocculation with a coagulant for rapid sedimentat ion of the protein. The sediment is collected on filter paper and stained with xylene brilliant cyanin G....

Anthocyanins, flavonoid compounds present in grapes and wines, were determined by reverse-phase high-performance liquid chromatography (RP-HPLC) with electrochemical detection (RP-HPLC-ED). The method developed consists of RP-HPLC gradient elution with voltammetric detection using a glassy carbon electrode after separation in an Inertsil ODS-3V analytical column. Good peak resolution was obtain...
