Several methods are available to predict cis-regulatory modules in DNA based on position weight matrices. However, the performance of these methods generally depends on a number of additional parameters that cannot be derived from sequences and are difficult to estimate because they have no physical meaning. As the best way to detect cis-regulatory modules is the way in which the proteins recog...
There is a critical need for standard approaches to assess, report and compare the technical performance of genome-scale differential gene expression experiments. Here we assess technical performance with a proposed standard 'dashboard' of metrics derived from analysis of external spike-in RNA control ratio mixtures. These control ratio mixtures with defined abundance ratios enable assessment o...
In thermodynamic analysis of internal combustion engine, the specific heats of working fluid is considered to be constant. Due to specific heats are functions of operation temperature of cycle, this consideration cause to several errors in the thermal analysis. In this paper, standard Otto cycle with three various types of specific heats ratios has been analyzed numerically and effect of these ...
Laboratory studies suggest that insulin-like growth factor I (IGF-I) promotes prostatic growth. The authors evaluated the association between benign prostatic hyperplasia and IGF-I and its binding protein IGFBP-3 in community-dwelling men to determine whether this laboratory finding is manifest at the population level. Participants (n = 471) were Olmsted County, Minnesota, Caucasian males aged ...
We investigated the age-related changes of the binding of [11C]CFT to striatal dopamine transporters (DATs) in vivo in Fischer 344 rats by positron emission tomography (PET). The tissue dissection method represented an age-related decrease in the uptake ratio of the striatum to the cerebellum and in the specific binding-to-nonspecific binding ratio of [11C]CFT. PET demonstrated an age-dependent...
the object of this cross sectional study was to determine the hcv subtype 3a envelope protein binding affinity with human leukocyte antigen. envelope 1 (e1) protein is one of the structural proteins responsible for entering the cells through the receptors. the binding affinity of e1 protein epitopes to the selected human leukocyte antigen (hla) class i alleles was investigated using the compute...
Bacteria can become transiently tolerant to several classes of antibiotics. This phenomenon known as persistence is regulated by small genetic elements called toxin-antitoxin modules with intricate yet often poorly understood self-regulatory features. Here, we describe the structures of molecular complexes and interactions that drive the transcription regulation of the ccdAB toxin-antitoxin mod...
The kinetics of 123I-FP-CIT in the brain for healthy subjects were studied. Twelve dynamic SPECT data sets (0- to 6-hr after an intravenous injection) from a Phase 1 clinical trial of 123I-FP-CIT were analyzed. Tracer concentrations in the striatum, midbrain, cerebellum and cerebral cortex were measured on the SPECT images co-registered with the corresponding MR images. High tracer accumulation...
background dermatophytosis is a cutaneous fungal infection with a worldwide occurrence. in dermatophyte infections, the release of keratinocyte cytokines, in the presence of dermatophyte antigens, causes an acute phase response; subsequently, the acute-phase proteins are produced by hepatocytes. mannose–binding lectin (mbl), an acute-phase protein, also acts as a kind of pattern recognition rec...
