OBJECTIVE Biomedical events extraction concerns about events describing changes on the state of bio-molecules from literature. Comparing to the protein-protein interactions (PPIs) extraction task which often only involves the extraction of binary relations between two proteins, biomedical events extraction is much harder since it needs to deal with complex events consisting of embedded or hiera...

We have analyzed 247 Brazilian mtDNAs for hypervariable segment (HVS)-I and selected restriction fragment-length-polymorphism sites, to assess their ancestry in different continents. The total sample showed nearly equal amounts of Native American, African, and European matrilineal genetic contribution but with regional differences within Brazil. The mtDNA pool of present-day Brazilians clearly ...

Mitochondrial DNA (mtDNA) variability was studied in a sample of 179 individuals representing the Czech population of Western Bohemia. Sequencing of two hypervariable segments, HVS I and HVS II, in combination with screening of coding-region haplogroup-specific RFLP markers revealed that most Czech mtDNAs belong to the common West Eurasian mitochondrial haplogroups (H, pre-V HV*, J, T, U, N1, W...

Immunosuppression of juvenile squirrel monkeys with combined azathioprine, prednisolone, and antilymphocyte globulin resulted in decreased antibody responses to viral antigens after primary infection with Herpesvirus saimiri (HVS). The virus was repeatedly isolated from the oropharynx of immunosuppressed monkeys but not from untreated infected controls. Thus immune factors are important in inhi...

Mutant forms of herpesvirus saimiri (HVS) subgroup C strain 488 with deletions in either STP-C488 or Tip were constructed. The transforming potentials of the HVS mutants were tested in cell culture and in common marmosets. Parental HVS subgroup C strain 488 immortalized common marmoset T lymphocytes in vitro to interleukin-2-independent growth, but neither of the deletion mutants produced such ...

PURPOSE Waldenström's macroglobulinemia (WM) is characterized by an overproduction of immunoglobulin M (IgM), which can lead to a hyperviscosity syndrome (HVS) and HVS-related retinopathy. Plasmapheresis is known to reduce serum viscosity (SV) and IgM levels. The purpose of this study was to investigate the effects of plasmapheresis on HVS-related retinopathy and retinal hemodynamic parameters ...

An alternative process to obtain a high degree of dewatering tailings that produces high-density product is presented in this article. This technology involves the combination particle grain size classification by hydrocyclones (HC) and horizontal vibratory screens (HVS). It makes it possible dewater grade performance. (HC-HVS) recovery water from coarse fraction (sands) through two hydrocyclon...

This paper summaries the state-of-the-art of image quality assessment (IQA) and human visual system (HVS). IQA provides an objective index or real value to measure the quality of the specified image. Since human beings are the ultimate receivers of visual information in practical applications, the most reliable IQA is to build a computational model to mimic the HVS. According to the properties ...

Hypervelocity stars (HVS) traverse the Galaxy from the central black hole to the outer halo. We show that the Galactic potential within 200 pc acts as a high pass filter preventing low velocity HVS from reaching the halo. To trace the orbits of HVS throughout the Galaxy, we construct two forms of the potential which reasonably represent the observations in the range 5–10 pc, a simple sphericall...

PURPOSE Hyperintense vessels (HVs) on fluid-attenuated inversion recovery (FLAIR) imaging are associated with the leptomeningeal collateral circulation in cases of arterial occlusive lesions. Nevertheless, the relationship between HVs on FLAIR imaging and arterial circulation time (ACT) on cerebral angiography has not been defined. METHODS We analyzed images of 11 patients with acute occlusio...
