drug resistance enables cancer cells to break away from cytotoxic effect of anticancer drugs. identification of resistant phenotype is very important because it can lead to effective treatment plan. there is an interest in developing classifying models of resistance phenotype based on the multivariate data. we have investigated a vibrational spectroscopic approach in order to characterize a sen...
چکیده سابقه و هدف: پتانسیل روش مایع به جامد (liquisolid comppcrs) جهت افزایش ویژگی های انحلال داروهای نامحلول در آب، در سال های اخیر مورد بررسی و به اثبات رسیده است. به تازگی استفاده از این روش در کنترل سرعت آزادسازی نیز مورد بررسی قرار گرفته است. در این مطالعه تأثیر پلیمرهای اودراجیت (eudragit) و hpmc (hydroxy prapyl methyl cellulose) بر کنترل رهش تئوفیلین (theophylline) از فرمولاسیون های مختل...
The integration of three-dimensional (3D) data with infrared thermography has received much attention for its potential use as input data for building energy simulations. Therefore, researchers have proposed methods to integrate 3D data with infrared thermography obtained by different sensors. These studies show the potential of the integration of 3D data and infrared thermography using various...
Forty-seven galaxies from the IRAS Bright Galaxy Sample with infrared luminosities Lm > 10 1 Lq have been measured at 1.3, 1.65, and 2.2 ¡im with beam diameters of 17", 33", and 55". These measurements, combined with 5" and 10" observations presented in an earlier paper, provide an opportunity to study the spatial distribution of the near-infrared emission in luminous IRAS galaxies. It is found...
We have developed an infrared imaging setup enabling in situ infrared images to be acquired, and expanded on capabilities of an infrared imaging as a high-throughput screening technique, determination of a critical thickness of a Pd capping layer which significantly blocks infrared emission from below, enhancement of sensitivity to hydrogenation and dehydrogenation by normalizing raw infrared i...
The Composite Infrared Spectrometer observed Jupiter in the thermal infrared during the swing-by of the Cassini spacecraft. Results include the detection of two new stratospheric species, the methyl radical and diacetylene, gaseous species present in the north and south auroral infrared hot spots; determination of the variations with latitude of acetylene and ethane, the latter a tracer of atmo...
We use near-infrared photometry of objects detected by IRAS to confirm four new T Tauri stars in Chamaeleon II. Observations of these sources generally agree with the T Tauri signatures of locus in the near-infrared color-color diagram, midinfrared spectral index, and IRAS far-infrared colors. Infrared properties of these stars are similar to optically selected T Tauri stars in Cha II, but are ...
