BACKGROUND High-throughput gene expression data can predict gene function through the "guilt by association" principle: coexpressed genes are likely to be functionally associated. METHODOLOGY/PRINCIPAL FINDINGS We analyzed publicly available expression data on normal human tissues. The analysis is based on the integration of data obtained with two experimental platforms (microarrays and SAGE)...

We present a numerical tool to compare directly the contrast-to-noise-ratio (CNR) of the attenuation- and differential phase-contrast signals available from grating-based X-ray imaging for single radiographs. The attenuation projection is differentiated to bring it into a modality comparable to the differential phase projection using a Gaussian derivative filter. A Relative Contrast Gain (RCG) ...

The current paper has presented the results of environmental testing winter durum wheat varieties in conditions southern part Rostov region. purpose study was to estimate productivity and grain quality various maturity groups. objects were 53 origins breeding, namely FSBSI “ARC “Donskoy”, RCG named after P. Lukiyanenko, FRAC other institutions. variety ‘Kristella’ used as a standard variety. Ac...

We study the problem of transforming a multichromosomal genome into another using Double-Cut-and-Join (DCJ) operations. We introduce the notion of DCJ scenario that does not break families of common intervals (groups of genes co-localized in both genomes). Such scenarios are called perfect, and generalize the notion of perfect reversal scenarios. While perfect sorting by reversals is NP-hard if...

Grey collie dogs have cyclic fluctuations in their blood cell counts caused by a regulatory defect of hematopoietic stem cells. To examine the role of stem cell factor (SCF) or its receptor in this disorder, we investigated the stimulatory effects of recombinant canine SCF (rc-SCF) on in vitro marrow cultures, cloned and sequenced the grey collie SCF gene, and treated three grey collies with rc...

OBJECTIVE The purpose of the study was to present the results of 15-year application in practical cardiology of the method of high-resolution registration and analysis of heart rate variability (HRV) for diagnosis of the cardiovascular pathology. METHODS Database consists of more than 46 thousand cases with different cardiovascular diseases. Here are shown some peculiarities of the HRV analys...

PURPOSE To investigate the effect of old age (3 vs. 18 months) on the retinal function of albino (Sprague-Dawley [SD]) and pigmented (Long-Evans [LE]) rats. METHODS Electroretinograms (ERG) were recorded in both albino (SD; 3 months old n = 16, 18 months old n = 16) and pigmented (LE; 3 months n = 16, 18 months n = 5) rats. Data are analyzed for photoreceptor, ON-bipolar, and retinal ganglion...

This is the first study reporting the evaluation of transgenic lines of tomato harboring rice chitinase (RCG3) gene for resistance to two important fungal pathogens Fusarium oxysporum f. sp. lycopersici (Fol) causing fusarium wilt and Alternaria solani causing early blight (EB). In this study, three transgenic lines TL1, TL2 and TL3 of tomato Solanum lycopersicum Mill. cv. Riogrande genetically...

Aerial image categorization plays an indispensable role in remote sensing and artificial intelligence. In this paper, we propose a new aerial image categorization framework, focusing on organizing the local patches of each aerial image into multiple discriminative subgraphs. The subgraphs reflect both the geometric property and the color distribution of an aerial image. First, each aerial image...

During the past decade, dynamic data have been obtained by recording from various external monitor ing devices following administration of various ra dioactive tagged materials. From the clinical point of view, the most obvious advantage of these tech niques is the external monitoring aspect, which is both atraumatic and convenient. Conversely, this aspect has hindered a sophisticated analysis ...
