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...

objective(s):psoriasis is an autoimmune disease that appears on the skin. although psoriasis is clinically and histologically well characterized, its pathogenesis is unknown in detail. the aims of this study were to evaluate the proteome of psoriatic patients' sera and to compare them with those of normal healthy human to find valuable biomarkers. materials and methods: in a case-control s...

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). the ...

background:isolates of staphylococcus aureus express a myriad of adhesive surface proteins that play important role in colonization of the bacteria on nasal and skin surfaces, beginning the process of pathogenesis. the aim of this study was to screen several of the microbial surface components recognizing adhesive matrix molecules (mscramms) genes among the isolate of s. aureus from hospitalize...

three new rimantadine schiff bases (rsbs) were prepared, and then the interaction of rsbs with bovine serum albumin (bsa) was investigated using fluorescence, synchronous fluorescence, uv-vis absorption spectroscopy under physiological conditions. the results showed that the three rsbs effectively quenched the intrinsic fluorescence of bsa via static quenching. binding constant (ka), number of ...
