sar-kuh porphyry copper deposit is located 6 km southwest of the sar-cheshmeh copper mine, kerman province, iran. based on field geology, petrography and fluid inclusions studies, four alteration types have been identified in the sar-kuh area. early hydrothermal alteration formed a potassic zone in the central parts of mamzar granite/grano-diorite stock and propylitic alteration in its peripher...

Various staining techniques are commonly used in biomedical research to investigate cellular morphology. By inducing absorption of light, staining dyes change the intracellular refractive index due to the Kramers-Kronig relationship. We present a method for creating 2D maps of real and imaginary refractive indices of stained biological cells using their thickness and absorptance. We validate ou...

BACKGROUND A prolonged QT interval can lead to malignant ventricular arrhythmias and sudden cardiac death, and has frequently been found in end-stage liver disease (ESLD). However, myocardial repolarization lability has not yet been fully investigated. We evaluated the QT variability index (QTVI), a marker of temporal inhomogeneity in ventricular repolarization and an abnormality associated wit...

THE bispectral index (BIS, Aspect Medical Systems Inc., Newton, MA) is a processed electroencephalographic variable which correlates with depth of hypnosis in adult patients during general anesthesia. It has also been used clinically to guide anesthetic drug administration, and to quantify the pharmacodynamic action of anesthetic drugs in the laboratory setting. BIS has previously been shown to...

The study purpose was to develop a patient's prognostic index (PI) reflecting the genetic information in cDNA microarray-based CGH experiment data for estimating a gastric cancer patient's survival time. The developed methodology was fit to and validated using data from the Cancer Metastasis Research Center at Yonsei University; 30 pairs of gastric tumors and normal gastric tissues were used in...

bentonite deposits of economic interest are widespread in tashtab mountains (khur), east of isfahan province, iran. several bentonite deposits have been developed in this area as a result of eocene volcanic alteration. these deposits are classified as khur bentonite horizon. xrd analyses reveal that alteration products consist of na-montmorillonite, kaolinite, quartz, calcite, and crystobalite....
