The binding of sodium n-dodecyl sulphate (SDS) to Aspergillus niger catalase in various ionic strengths at pH 6.4 and a temperature of 27? and 37?C has been studied over a range of SDS concentrations using equilibrium dialysis and fluorescence spectroscopy techniques. The binding data were used and interpreted in terms of theoretical models (Scatchard Equation and Wyman Binding Potential). ...

dietary flavonoids show beneficial effects in the prevention of chronic diseases. however, flavonoid bioavailability is poor, probably due to their interaction with serum albumins. in the current work, the binding interactions of eight related flavonoids, sharing a similar core structure, with bovine serum albumin (bsa) were investigated by fluorescence spectroscopy. the binding affinities of t...

to obtain drugs which are more selective at benzodiazepine (bzd) receptors, design and synthesis of functionally selective ligands for bzd receptors is the current strategy of our pharmaceutical chemistry department. the affinity of newly synthesized ligands is assessed by radioligand receptor binding assays. based on our previous studies, 2-phenyl-5-oxo-7-methyl-1,3,4-oxadiazolo[a,2,3]-pyrimid...

background:the dynamic binding capacity (dbc) of a chromatography matrix in protein purification is the amount of the total protein absorbed into the matrix, before occurrence of a significant break in the breakthrough curve. optimization of the process criteria for maximum dbc avoids extra process scale-up and reduces the processing time, costs and protein loss. taguchi method is a simple usef...

conclusions consequently, small diameter scnt interaction with nucleic acid bases is noncovalent. also, the results revealed that small diameter scnt interaction especially scnt (4, 4) with nucleic acid bases can be useful in practical application area of biomedical fields such detection and drug delivery. objectives hence, the quantum mechanics (qm) method based on ab initio was used for this ...

the reaction of copper(ii) chloride and zinc(ii) chloride with n-(2-methylphenyl)-3-(1'-salicylaldehydene-2'-imine-ethane)-butanamide(h2l2a) or (mpsb), n-(2-methylphenyl)-3-(1'-(3'-methoxysalicylaldehydene-2'-imine-ethane)-butanamide (h2l2b) or (mpmsb) and n-(2-methylphenyl)-3-(1'-(2'-hydroxyacetylene-2'-imine-ethane)-butanamide (h2l2c) (mphb) leads to th...

background: hypertrophic cardiomyopathy is a genetic disorder with a prevalence rate of 0.2% in the general population. it comes from mutations in sarcomeric proteins. cardiac myosin-binding protein c3 is one of the critical genes in hypertrophic cardiomyopathy (hcm) and sudden cardiac death, accounting for about 20% of hcm-causing mutations. genetic testing is recommended in patients with hcm....

background: serum levels of lipocalin 2 (lcn 2) and retinol-binding protein-4 (rbp 4), increase in type 2 diabetes mellitus (t2dm). we sought to determine whether serum lcn 2 and rbp 4 change after an intervention with omega-3 fatty acids supplementation in diabetic patients. methods: forty-five type 2 diabetic patients from iranian diabetic association in tehran, iran in 2013 were randomly rec...

objective(s): the periodic binding of protein expressed by mycobacterium tuberculosis h37rv with the host cell receptor molecules i.e. fibronectin (fn) is gaining significance because of its adhesive properties.  the genome sequencing of m. tuberculosis h37rv revealed that the proline-glutamic (pe) proteins contain polymorphic gc-rich repetitive sequences (pgrs) which have clinical importance i...
