Drought stress in plants, the change (increase or decrease) in the production of plant proteins. Proteomics in recent years one of the most powerful tools that help us to study the changes in protein In order to investigate the proteome of wheat leaves in response to terminal drought, two genotypes susceptible and resistant wheat genotypes were evaluated under irrigated (non-stress) and rain-fe...

BACKGROUND T-SPOT.TB (T-SPOT), an interferon-gamma release assay, has shown promise as a diagnostic tool for active tuberculosis (TB), and its use is expanding. Addition of the T-Cell Xtend (TCX) reagent may allow delayed processing, and this characteristic is important for using this test in the field. However, limited data is available on the usefulness of T-SPOT with TCX as a field test for ...

BACKGROUND AND PURPOSE The presence of active contrast extravasation (the spot sign) on computed tomography (CT) angiography has been recognized as a predictor of hematoma expansion in patients with intracerebral hemorrhage. We aim to systematically characterize the spot sign to identify features that are most predictive of hematoma expansion and construct a spot sign scoring system. METHODS ...

The reliability of visual filling-in at the blind spot and how it is influenced by the distribution of spatial attention in and around the blind spot were studied. Our data suggest that visual filling-in at the blind spot is 1) less reliable than it has been assumed, and 2) easier under diffused attention around the blind spot than under focal attention restricted in the blind spot. These findi...

The growth and breakdown of localised disturbances into a turbulent spot in a Mach 2 boundary-layer flow have been investigated by direct numerical simulation. In particular, the interaction of a turbulent spot with a shock-induced separation bubble is studied. The primary vortex structures triggered by the injected low momentum fluid and the metamorphosis of the hairpin structures into a turbu...

In late 2009, Amazon introduced spot instances to offer their unused resources at lower cost with reduced reliability. Amazon’s spot instances allow customers to bid on unused Amazon EC2 capacity and run those instances for as long as their bid exceeds the current spot price. The spot price changes periodically based on supply and demand, and customers whose bids exceed it gain access to the av...

BACKGROUND Spot welding is a type of resistance welding in which pieces of metals are pressed together and an electric current is passed through them. Spot welders are at risk of contact with some potentially hazardous agents but there are few studies about the respiratory effects of spot welding. AIMS Our objective was to study lung function and respiratory symptoms among spot welders and of...

OBJECTIVE The spot sign is related with the risk of hematoma expansion in spontaneous intracerebral hemorrhage (ICH). However, not all spot sign positive patients undergo hematoma expansion. Thus, the present study investigates the specific factors enhancing the spot sign positivity in predicting hematoma expansion. METHODS We retrospectively studied 316 consecutive patients who presented bet...

MOTIVATION DNA microarrays are an experimental technology which consists in arrays of thousands of discrete DNA sequences that are printed on glass microscope slides. Image analysis is an important aspect of microarray experiments. The aim of this step is to reduce an image of spots into a table with a measure of the intensity for each spot. Efficient, accurate and automatic analysis of DNA spo...
