The use of Raman spectroscopy to analyze blood biochemistry and hence distinguish between normal abnormal was investigated. samples were obtained from 20 patients who clinically diagnosed with cervical cancer 10 healthy volunteer. imprint put under the Olympus microscope several points chosen for measurement. All spectra collected at a Jobin‐Yvon LabRAM HR800 Spectrometer NIR 830 nm laser. It is shown that serum control group can be discriminated when multivariate statistical methods...
Based in high sensitivity and specificity reported recently detection of the cancer, technique Raman spectroscopy is proposed to discriminate between breast leukemia cervical cancer using blood serum samples from patients officially diagnosed. In order classify spectra, clustering method known as Super Paramagnetic Clustering based on statistical physics concepts with a stochastic approach was implemented. Comparing firstly average spectra three cancers, some peaks that allowed...
The use of Raman spectroscopy to analyze blood biochemistry and hence distinguish between normal abnormal was investigated. Blood samples were obtained from 6 patients who clinically diagnosed with leukemia healthy volunteers. imprint put under the microscope several points chosen for measurement. All spectra collected by a confocal micro‐spectroscopy (Renishaw) NIR 830 nm laser. It is shown that serum control group can be discriminated when multivariate statistical methods principal...
In the last decade, complex networks have widely been applied to study of many natural and man-made systems, extraction meaningful information from interaction structures created by genes proteins. Nevertheless, less attention has devoted metabonomics, due lack a network representation spectral data. Here we define technique for reconstructing data sets, where nodes represent bins, pairs them are connected when their intensities follow pattern associated with disease. The structural analysis...
The use of Raman spectroscopy to analyze biopsy biochemistry and hence distinguish between the breast cancer stages was investigated. samples were obtained from 13 patients who clinically diagnosed with cancer. A preliminary diagnosis some patient realized by pathologist Cancer Institute. biopsies put under microscope several points chosen for measurement. All spectra collected at a Jobin‐Yvon LabRAM HR800 Spectrometer NIR 830 nm laser. It is shown that can be discriminated when Principal...
A bioconjugation reaction is used to obtain fd viruses with one gold nanoparticle at the tip and nanowire-like structures.
The open photoacoustic cell was used to monitor the evolution rate of oxygen from tomato leaves. Estimates relative amount released in vivo and situ conditions as influenced by ambient temperature are being presented. Photorespiration phenomenon is shown dominate above a critical temperature. this point analyzed function environmental
We present the results of an upgrade to D0 muon system. Scintillating counters have been added existing central system provide rejection for cosmic ray muons and out-of-time background, additional fast timing information in upgraded Tevatron. Performance from 1994-1996 Tevatron run are presented.
A photoacoustic method for the determination of heat capacity per unit volume (ρCp), at room temperature, thin metallic foils is presented. The based on use a variant conventional cell.
Currently, there is a belief that drugs used after the expiration date no longer work, or even these can cause some damage. In present several types of on market with different dates are analyzed to find out if these, expired date, spectroscopic differences from those whose still valid. This study Raman spectroscopy technique determine chemical composition drugs. To measure drug spectra, Horiba equipment, LabRam HR800, was an Olympus confocal microscope focusing laser 830 nm and 17 mW...
Abstract A high rate of silver nanoparticle formation, effective against the Escherichia coli ( E. ) bacterium, was obtained for first time by means a simple, eco-friendly, and low-cost green method in solution agave inulin. The study carried out using traditional method, which effects concentration inulin, AgNO 3 , temperature, pH on synthesis were analyzed UV-Vis spectroscopy transmission electron microscopy (TEM). Most nanoparticles produced spherical with size less than 10 nm. In sample...
In this article, we use a discrete system to study the opinion dynamics regarding electoral preferences of nontendentious group agents. To measure level preference, continuous space is used, in which preference (opinion) can evolve from any political option, other; for regime three parties, circle convenient space. model nonbiased society, new agents are considered. Besides their opinion, they have attribute: an individual iterative monoparametric map that imitates process internal...
In this paper, we present a different way to the standard methods classify Raman spectra whose grouping process is based on phenomenon of clustering observed in nature at atomic level and correctly described by statistical physics model known as Potts model, which represents interacting spins crystalline lattice. This method super paramagnetic (SPC), allows identifying hierarchical structures data banks. novel method, assigned spin each point (Raman spectrum) introduced an interaction...
