The identification of genetic variants associated with common disease is accelerating rapidly. "Multiplex tests" that give individuals feedback on large panels of genetic variants have proliferated. Availability ...

Silk is a vector for collective behaviour in many spinning arthropods, including social spiders, social caterpillars, and some spider mites. In this study, the potential for silk-mediated collective choices is evaluated for the two-spotted spider mite Tetranychus urticae. This subsocial mite lives in large colonies on plants, sheltered under a ...

Grass pollen allergic patients are concomitantly exposed and sensitized to pollens from multiple Pooideae (i.e. common grass) species. As such, they are currently desensitized by allergen-specific immunotherapy using extracts made from mixes of pollens from Anthoxanthum odoratum, Dactylis glomerata, Lolium perenne, Phleum pratense and Poa pratensis. Herein, we demonstrate that ...

ABSTRACT: The Brazilian network for genotyping is composed of 21 laboratories that perform and analyze genotyping tests for all HIV-infected patients within the public system, performing approximately 25,000 tests per year. We assessed the interlaboratory and intralaboratory reproducibility of genotyping systems by creating and implementing a local external quality control ...

Aims: We have previously shown that the (±)-[(13) C]-pantoprazole breath test is a promising noninvasive probe of CYP2C19 activity. As part of that trial, plasma, breath test indices and CYP2C19 (*2, *3, and *17) genotype were collected. Here, we examined whether [(13) C]-pantoprazole exhibits enantioselective pharmacokinetics and whether this enantioselectivity ...

BACKGROUND: The Coombs' test, which detects immunoglobulin or complement on RBC surfaces, has long been the standard for laboratory confirmation of immune-mediated hemolytic anemia (IMHA), a common cause of hemolytic anemia in the dog. This test, however, suffers from relatively low sensitivity. Optimization of test sensitivity would lead to fewer ...

Although positive direct Coombs' tests occur in most patients with active systemic lupus erythematosus (SLE), haemolytic anaemic associated with antibody to erythrocytes (E) occurs in less than 10%. Our studies show an association between positive direct Coombs' tests and both the presence of circulating immune complexes and diminished activity of ...

Severe autoimmune hemolytic anemia is described as the presenting manifestation of malignant thymoma.
