SUMMARY Full length cDNA sequences are an important resource for the research community but are currently intermingled with other sequences. We have identified the human full length insert cDNA sequences in GenBank and placed them in a single location, the Human Transcript Database. AVAILIBILITY: The Human Transcript Database is available at http://www.hgsc.bcm.tms.edu/HTDB/. CONTACT John Bou...

background: occupational contact dermatitis, especially in hand, is one of the most common occupational disorders. the present study aimed at evaluating patients with occupational allergic contact dermatitis (acd) caused by common allergens based on occupation type and disease history.   methods: this cross-sectional study aimed at evaluating the data of the patients with probable diagnosis of ...

BACKGROUND Genotyping Mycobacterium tuberculosis isolates allows study of dynamics of tuberculosis transmission, while geoprocessing allows spatial analysis of clinical and epidemiological data. Here, genotyping data and spatial analysis were combined to characterize tuberculosis transmission in Vitória, Brazil, to identify distinct neighborhoods and risk factors associated with recent tubercul...

Investigation of vertical vibrations of a railway turnout is important in designing track components under moving loads of trains. In this paper, the turnout is simulated by a linear finite element model with modal damping. A section of the turnout has a length of 36 sleeper spans surrounding the crossing. Rails and sleepers are modeled with uniform Rayleigh- Timoshenko beam elements. The rail...

Moving beyond the limits of silicon transistors requires both a high-performance channel and high-quality electrical contacts. Carbon nanotubes provide high-performance channels below 10 nanometers, but as with silicon, the increase in contact resistance with decreasing size becomes a major performance roadblock. We report a single-walled carbon nanotube (SWNT) transistor technology with an end...

The flow of electrical current through a microscopic actual contact spot between two conductors is influenced by the flow through adjacent contact spots. A smoothed version of this interaction effect is developed and used to predict the contact resistance when the statistical size and spatial distribution of contact spots is known. To illustrate the use of the method, an idealized fractal rough...

Receptor-ligand couples in the cell-cell contact interface between a T cell and an antigen-presenting cell form distinct geometric patterns and undergo spatial rearrangement within the contact interface. Spatial segregation of the antigen and adhesion receptors occurs within seconds of contact, central aggregation of the antigen receptor then occurring over 1-5 min. This structure, called the i...
