the application of traditional nmo-correction techniques in the processing of seismic data may result in severe distortion. this distortion is observed as a decrease in frequency content (nmo stretch). this may be seen as the source of problems in the processing with stretch. in this paper, cnmo method is applied which doesn't have the `stretching effects' of conventional nmo correcti...

A stable reduced graphene oxide (rGO) was prepared and characterized by X-ray diffraction (XRD) and laser Raman spectroscopy. Steady state and time-resolved fluorescence quenching studies have been carried out to elucidate the process of electron transfer from excited pyranine (POH) into the rGO dispersion. POH adsorbed strongly on rGO dispersion with an apparent association constant of 33.4 (m...

objective: low density lipo-protein receptor- related protein (lrp) is the most important cholesterol receptor in neurons. it serves as a receptor for apoe protein which is the most important risk factor for alzheimer’s disease. lrp also contributes to the ligation of lipoproteins with apoe in neurons. association between lrp c766t and alzheimer’s disease in iranian patients with late onset alz...

background: obesity is a common health problem around the world. studies have shown inverse relationship between serum vitamin d levels with obesity among patients and healthy population. the aim of this present study is to examine the relationship between serum vitamin d levels with general and abdominal obesity among migraine patients. methods: the present study is a cross‑sectional and 66 mi...

Human immunodeficiency virus type 1 (HIV-1) integrase is essential for viral replication. Integrase inserts the viral DNA into the host DNA. We studied the association of integrase to fluorescently labeled oligonucleotides using fluorescence correlation spectroscopy. The binding of integrase to the fluorescent oligonucleotides resulted in the appearance of bright spikes during fluorescence corr...

When we use Scatchard analysis for insulin receptor on intact cells, internalization of insulin may affect the Scatchard analysis. In this study, results from Scatchard analysis for insulin receptor on hepatocytes of streptozotocin (STZ)-induced diabetic rats were compared with those from association and dissociation studies and those from Scatchard analysis using hepatocyte membrane which does...

Anilinonaphthalenesulfonate (ANS) and tryptophan compete for binding to the trp repressor protein; thus, the fluorescence decrease associated with ANS dissociation can be used as a fluorometric marker for tryptophan binding to the protein. Using this approach, the tryptophan equilibrium dissociation constant was measured at 25 degrees C to be 3.7 (+/- 1.2) X 10(-5) M, a value which compares fav...
