BACKGROUND Annexin A2 (ANXA2), a member of the annexin family of cytosolic Ca(2+)-binding proteins, plays a pivotal role in vascular biology. Small amounts of this protein and S100A10 protein are exposed on the surface of endothelial cells (ECs). They control fibrinolysis by recruiting tissue-type and urokinase-type plasminogen activators from the plasma. Nutritional studies indicate that two m...

Ninety-three children in a primary school and 59 children in two first-year classes of a secondary school were asked individually to observe a paragraph of random letters arranged to resemble text, and to compare the perceptual effects on its clarity of coloured plastic sheets overlaid on the text. A total of 29 colours were compared using 10 coloured plastic sheets and 19 pairwise combinations...

Go on Strike It was mid morning on Tuesday, October 29. We had just finished rounds at the Hospital Universitario del Valle (HUV) in Cali, Colombia. To my surprise, the resident, Diego, turned to me and said, “I have to go now— the strike is beginning.” He grabbed a rolled-up hand-painted banner and, along with nearly every resident in the hospital, headed out to the street. At the same moment,...

H uman T cell lymphotropic virus type I (HTLV-I) is a mammalian retrovirus that has a tropism for mature T lymphocytes and an association with rare clinical disorders (1, 2). HTLV-I infection is endemic in a number of geographic regions which include parts of Japan, the Caribbean, South America, and Africa. Despite very high rates of infection in endemic areas where as many as 30% of the popula...

INTRODUCTION Arteriosclerotic changes can lead to circulatory disturbances in various areas of the human vascular system. In addition to pharmacological therapy and the management of risk factors (e. g. hypertension, diabetes, lipid metabolism disorders, and lifestyle), surgical interventions also play an important role in the treatment of arteriosclerosis. Long-segment arterial occlusions, in ...

Computed tomography (CT) uses thousands of x-ray transmission measurements taken at different angles around a patient to produce three-dimensional cross-sectional images the human body. That technology allows physicians visualize their patients’ internal anatomy, as shown in opening image, and reveals presence acute chronic diseases consequences injury remarkable detail. Prior integration CT in...

We present a linguistically-motivated technique for the recognition and grouping of simplex noun phrases (SNPs) called LinkIT. Our system has two key features: (1) we efficiently gather minimal NPs, i.e. SNPs, as precisely and linguistically defined and motivated in our paper ; (2) we apply a refined set of postprocessing rules to these SNPs to link them within a document. The identification of...
