background: communication is very important in human societies in connection with the exchange of ideas and information between the instructor and student. the current research aimed to study factors that influence the interaction between the instructor and student from the perspective of shushtar medical sciences students. methods: this descriptive - cross sectional study was conducted in ahva...

the binding data for interaction of a homologous series of n-alkyl sulfates with alkyl chainlengths from c8 to c12 with insulin were analyzed on basis of hill equation for two classes ofbinding sites .the intrinsic gibbs free energies were calculated and resolute on basis ofelectrostatic and hydrophobic contributions the estimation of these contributions reveals themajor role of electrostatic i...

The flavin-containing monooxygenases (FMOs) are important for the oxidation of a variety of environmental toxicants, natural products, and therapeutics. Consisting of six family members (FMO1–5), these enzymes exhibit distinct but broad and overlapping substrate specificity and are expressed in a highly tissueand species-selective manner. Corresponding to previously identified regulatory domain...

abstractintroduction: cancer is caused by genetic abnormalities, such as mutation of ontogenesis or tumor suppressor genes which alter downstream signaling pathways and protein-protein interactions. comparison of protein interactions in cancerous and normal cells can be of help in mechanisms of disease diagnoses and treatments. methods: we constructed protein interaction networks of cancerous a...

background: clopidogrel is a prodrug that converts in the liver to an active thiol metabolite, which irreversibly inhibits the platelet p2y12 adenosine diphosphate receptor. it seems that methadone as cyp2c19 inhibitor affects ticlopidine activity in vivo. this study aimed to test the ability of methadone in changing ticlopidine pharmacokinetics. methods: we conducted a case–control study in 10...

background some herbal anticancer agents have direct interactions with dna. objectives the present study aimed to investigate the interaction of ctdna with rosemary flowers. materials and methods we used uv-vis, fluorescence and circular dichroism (cd) spectroscopic techniques. results the absorption of dna at 260 nm increased on addition of rosemary. herb extract quench the fluorescence of etb...

background: today, issues such as water shortage, difficulties and costs related to supplying safe water, and anomalous concentrations of heavy metals in groundwater and surface water resources, doubled the necessity of access to technical methods on removing these pollutants from water resources. methods: in this lab study, cationic resin purolite s-930 (with co-polymer styrene di-vinyl benzen...

CONSPECTUS: Cross-conjugated molecular cruciforms are intriguing platforms for optoelectronic applications. Their two intersecting π-conjugated arms allow independent modulation of the molecules' HOMO and LUMO levels and guarantee a well-defined optical response to analyte binding. In addition, the rigid cross-conjugated geometries of these molecules allow their organization in two- and three-d...

one of the best strategies to control bacterial wilt caused by ralstonia solanacearum (smith) is generally based on breeding resistant cultivars. the information obtained from the expression of plant defense genes will provide new insight for improving plant resistance against pathogens. this study was to identify inducible genes under defense no death (dnd) reaction of tobacco (nicotiana tabac...

geometric and material nonlinear behavior of slender webs in i-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. in addition, the effects of flange and web slenderness rati...
