Of the currently identified protein sequences, 99.6% have never been observed in the laboratory as proteins and their molecular function has not been established experimentally. Predicting the function of such proteins relies mostly on annotated homologs. However, this has resulted in some erroneous annotations, and many proteins have no annotated homologs. Here we propose a de-novo function pr...

Aim: In present Pharmaceutical trend, natural excipients are gaining more importance because of their availability, safety, performance, and cost. The work aimed at extraction the mucilage from stem Musa paradisiaca (banana) evaluation extracted for its binding disintegrating properties with Paracetamol as a model drug.
 Methodology: was by aqueous method followed precipitation evaluated v...

with “BD SST 1 double centrifugation” (P ,0.0001, paired t-test). Deming regression analysis yielded the following: slope 5 1.16 [95% confidence interval (95% CI), 1.03–1.29]; intercept 5 0.04 mg/L (95% CI, 0.02– 0.06 mg/L). Table 1 shows the assay values of the six apparently falsepositive results. These results prompted a second phase, during which the BD Thrombin sample was also centrifuged ...

Horseradish peroxidase (HRP), has gained significant interests in biotechnology, especially in biosensor field and diagnostic test kits. Hence, its solvent-exposed lysine residues 174, 232, and 241 have been frequently modified with the aim of improving its stability and catalytic efficiency. In this computational study, we investigated the effects of Lys-to-Glu substitutions on HRP structure t...

      Calcium acetate is used as an oral phosphate binder to control hyperphosphatemia in patients with chronic renal failure. Compared to calcium carbonate, control of hyperphosphatemia can be achieved at lower calcium administration with calcium acetate which likely reduces the risk of hypercalcemia. In this study, various formulations of calcium acetate tablets were prepared and their disint...

Objective: Shortia and other members of the Diapensiaceae family have ethnomedicinal history in both Eastern and Western hemispheres. Based on ethnopharmacological and chemosystematic evidence, pharmacological and toxicological bioassays were conducted on the rare plant Oconee Bell, Shortia galacifolia. Materials and Methods: Extracts were examined in assays for antimutagenicity, antitumor and ...

Indium is a heavy metal belonging to group IIIa. It is believed that indium may interfere with iron metabolism from the sites of absorption, transportation, utilization and storage in the cells. The present investigation was established to study and compare the binding of iron and indium to human apo-transferrin (apo-tf). Pure human apo-tf was used and the binding activity of iron and indium, a...

Human serum albumin (HSA) is the most abundant protein in the blood plasma. Molecular dynamics simulations of subdomain IIA of HSA and its complex with salicylic acid (SAL) were performed to investigate structural changes induced by the ligand binding. To estimate the binding affinity of SAL molecule to subdomains IB and IIA in HSA protein, binding free energies were calculated using the Molecu...

The interaction of hGH with some metal ions ( ) at 27°C in NaC1 solution, 50 mM was studied using Isothermal titration calorimetry. There is a set of three identical and non-interacting binding sites for binding of all these metal ions, expect . The intrinsic association equilibrium constants () are not very different for  and , and also their molar enthalpies of binding (KJ/mol for  and  KJ/mo...
