The current paper presents an approach for analyzing the Electronic Health Records (EHRs) with the goal of automatically identifying morphologic negation such that swapping the truth values of concepts introduced by negation does not interfere with understanding the medical discourse. To identify morphologic negation we propose the RoPreNex strategy that represents the adaptation of our PreNex ...

Introduction: The Vallis Schröteri exists on the Aristarchus Plateau (305-313 °E, 22-30 °N) which is a topographic high surrounded by basaltic maria. The rille appears a singular sinuous rille as meandering primary rille including a more meandering inner rille. Typical sinuous rilles are 20 to 40 km in length and less than 1 km in width [1], however, the primary rille of Vallis Schröteri has be...

PURPOSE A solid tumor embedded in host tissue is a three-dimensional arrangement of cells and extracellular matrix that acts as a sink of oxygen and cell nutrients, thus establishing diffusional gradients. This and variations in vascular density and blood flow typically produce intratumoral regions of hypoxia and acidosis, and may result in spatially heterogeneous cell proliferation and migrati...

and the other 4 developed morphologic changes while receiving HAART. The average time to morphologic change was 20 months (22 months for those receiving dual nucleoside therapy and 19 months for those receiving HAART). All of the patients in this report received stavudine for an average of 19 months (table 2). As the number of patients receiving antiretroviral therapy increases in the developin...

Cultured rat prostatic adenocarcinoma (AT3) cells infected with the challenge virus standard (CVS) strain of fixed rabies virus showed characteristic morphologic features of apoptosis, evidence of oligonucleosomal DNA fragmentation, and expression of the Bax protein. CVS-infected Bcl-2-transfected AT3 cells did not demonstrate these features. Adult ICR mice inoculated intracerebrally with CVS s...

Introduction Thrombotic microangiopathy is a term for a morphologic lesion characterized by platelet and fibrin thrombi involving the microvasculature. The morphologic lesions thus overlap between hemolytic syndrome (HUS), thrombotic thrombocytopenic purpura (TTP), and the lesions seen in scleroderma and malignant hypertension. HUS/TTP typically involves glomeruli and smaller vessels, whereas s...
