hydrothermal alteration processes are extensively took place on volcanic and pyroclstics of takestan area. existence of abundant, deep fracturing and subvolcanic intrusions are enhanced extend hydrothermal alteration zones. the following alteration zones are determined: propylitic, argillic, advanced argillic and sillicic. there are outcropped and widespread in different size and limit. formati...

Little is known about genetic regulation of the development of white matter. This knowledge is critical in understanding the pathophysiology of neurodevelopmental syndromes associated with altered cognition as well as in elucidating the genetics of normal human cognition. The hemideletion of approximately 25 genes on chromosome 7q11.23 that causes Williams syndrome (WS) includes genes that regu...

We describe a 74-year-old woman with no family history of breast cancer who presented with a high-grade myoepithelial carcinoma. Diagnosis was supported by immunohistochemical staining for both epithelial (ie, keratin) and myoepithelial (eg., p63, S-100, actin) differentiation. Because the patient reported that her family had an extensive history of neoplasm, a genetic study was ordered. To our...

Microbes have co-evolved with human beings for millions of years. They play a very important role in maintaining the health of the host. With the advancement in next generation sequencing technology, the microbiome profiling in the host can be obtained under different circumstances. This review focuses on the current knowledge of the alteration of complex microbial communities upon the infectio...

Spectral properties of photoinduced fiber Bragg gratings written in germanosilicate fibers and subjected to hydrogen loading at a pressure of 150-170 MPa have been studied. It was observed, for the first time to our knowledge, that hydrogen dissolution in the glass network at such high pressures leads not only to a Bragg wavelength shift but also to a considerable alteration of the grating refl...

Considering the significance of continuous medical education and its role in the quality of the presented health and treatment services, and the holding of more than 3000 of such programs, this study was carried out to determine the effect of continuous medical educational program regarding renal stones during the years 1997-1998. In this study, the educational trial strategy was carried out o...

Wettability alteration is an important method for increasing oil recovery from oil-wet carbonate reservoirs. Chemical agents like surfactants are known as wettability modifiers in carbonate systems. Oil can be recovered from initially oil-wet carbonate reservoirs by wettability alteration from oil-wet to water-wet condition with adding dilute surfactant and electrolyte solutions. This paper inv...

This paper presents a quantitative modeling for delineating alteration zones in the hypogene zone of the Miduk porphyry copper deposit (SE Iran) based on the core drilling data. The main goal of this work was to apply the Ordinary Kriging (OK), Artificial Neural Networks (ANNs), and Concentration-Volume (C-V) fractal modelings on Cu grades to separate different alteration zones. Anisotropy was ...

A superkine variant of interleukin-2 with six site mutations away from the binding interface developed from the yeast display technique has been previously characterized as undergoing a distal structure alteration which is responsible for its super-potency and provides an elegant case study with which to get insight about how to utilize allosteric effect to achieve desirable protein functions. ...
