Tartaric acid modified wheat bran was utilized as adsorbent to remove methyl blue, a basic dye from aqueous solution. Batch experiments were carried out to study the effect of various experimental parameters such as initial solution pH, contact time, initial dye concentration and adsorbent dosage, on dye adsorption. The results showed that the modification of wheat bran by tartaric acid signifi...

BACKGROUND P-113 (AKRHHGYKRKFH-NH2) is a 12-amino-acid histidine-rich peptide derived from histatin 5 that is highly degradable in high salt concentrations and biological fluids such as serum, plasma and saliva. Nal-P-113, a novel antimicrobial peptide whose histidine residues are replaced by the bulky amino acids β-naphthylalanine, causes the antimicrobial peptide to retain its bactericidal ac...

Parathyroid glands from laying hens were also  xed in percent glutaraldehyde in phosphate buffer (0.1 M, 7.3 pH) for araldite embedding and used for electron microscopy. For routine histological observations, sections of 5 to 6 um thickness were cut and stained by, Mayer’s haemalum and eosin-phloxine, Masson’s trichrome, Crossman’s modi cation of Mallory’s triple stain, van Gieson’s method fo...

Complement peptide receptors (nomenclature as agreed by the NC-IUPHAR subcommittee on [113]) are activated endogenous ~75 amino-acid anaphylatoxin polypeptides C3a and C5a, generated upon stimulation of complement cascade. C5a exert their functions through binding to (C3a receptor, receptor 1 2), causing cell recruitment triggering cellular degranulation that contributes local inflammation.

The effects of blue light and calcium on elongation of hypocotyl segments of Cucumber (Cucumis sativa L. cv Burpee's Pickler) were studied. Cucumber seedlings grown in dim red light showed a rapid decline in the rate of hypocotyl elongation when irradiated with high intensity (100 micromoles per square meter per second) blue light. In intact, 4-day-old seedlings the inhibition began within 2 mi...

Acid azo dyes, most of them naphtholdisulfonic acid derivatives, were given intraperitoneally to rats and their effect on "alkaline" ribonuclease activity was studied in total homogenates of kidney cortex and liver. Acid treatment was used to release bound enzyme activity. Several of the dyes, including trypan blue, increased RNase activity in both organs 3 days after administration of single d...
