PURPOSE The objective of this study was to comparatively assess the bone regenerative capacity of absorbable collagen sponge (ACS), biphasic calcium phosphate block (BCP) and collagenated biphasic calcium phosphate (CBCP) loaded with a low dose of recombinant human bone morphogenetic protein-2 (rhBMP-2). METHODS The CBCP was characterized by X-ray diffraction and scanning electron microscopy....

Soluble proteins make up 6.4–8.3% of plasma by weight [1], a value comparable to their concentration in cell water [2]. Many plasma proteins are synthesized by the liver. Their concentrations may decrease in the setting of liver disease, malnutrition or protein-losing states such as nephrotic syndrome, severe burns, bowel inflammation, intestinal lymphangiectasia or major bleeding episodes. The...

In rhizobia, besides the constitutive acyl carrier protein (AcpP) involved in the biosynthesis and transfer of common fatty acids, there are at least three specialized acyl carrier proteins (ACPs): (1) the flavonoid-inducible nodulation protein NodF; (2) the RkpF protein, which is required for the biosynthesis of rhizobial capsular polysaccharides; and (3) AcpXL, which transfers 27-hydroxyoctac...

background and objectives: beta-thalassemia continues to be a cause of significant burden to the society particularly in the poorer developing countries. although sophisticated methods of screening have become available, a hunt for a cheap, rapid, objective screening method still remains elusive. thus, the objectives are to study the validity of naked-eye-single-tube-osmotic-fragility-test (nes...

specificity is determined by the condensing enzyme, namely 8-ketoacyl-[acyl-carrier-proteinlsynthase 11. For the barley complex they are CoA derivatives which give rise to the C,,, C,, and C,, 3-oxoacyl key intermediates. One can speculate that the condensing enzyme activity specified by the cer-cqu-determined polypeptide is responsible for the noted substrate specificity. Therefore, should one...

S-peptide (residues 1-20) and S-protein (residues 21-124) are the enzymatically inactive products of the limited digestion of ribonuclease A by subtilisin. S-peptide binds S-protein with high affinity to form ribonuclease S, which has full enzymatic activity. Recombinant DNA technology was used to produce a fusion protein having three parts: carrier, spacer, and target. The two carriers used we...

receptors and proteins are overexpressed in many human cancer cell membranes rather than normal tissues and are considered as the main molecular targets. specific tumor- targeting molecules which have high affinity for these receptors can be valuable tools as carrier molecules for targeted cancer therapy and imaging. pharmacokinetics and bioavailability of diagnostic and therapeutic agents are ...
