POSTPOLIO SYNDROME (PPS) REFERS to new, late manifestations occurring many years after acute poliomyelitis infection. Over the last 25 years, PPS has become a relatively common problem encountered by primary care physicians. A 1987 National Health Interview Survey estimated that about half of the 640000 survivors of paralytic poliomyelitis in the United States hadnewlatemanifestationsofPPS. Sub...

As the University of Minnesota Biocatalysis/Biodegradation Database (UM-BBD, http://umbbd.ahc.umn.edu/) starts its second decade, it includes information on over 900 compounds, over 600 enzymes, nearly 1000 reactions and about 350 microorganism entries. Its Biochemical Periodic Tables have grown to include biological information for almost all stable, non-noble-gas elements (http://umbbd.ahc.um...

Prepositional phrases (PPs) express crucial information that knowledge base construction methods need to extract. However, PPs are a major source of syntactic ambiguity and still pose problems in parsing. We present a method for resolving ambiguities arising from PPs, making extensive use of semantic knowledge from various resources. As training data, we use both labeled and unlabeled data, uti...

A new, simple, rapid, sensitive and selective spectrophotometric kinetic method for Ag(I) traces determination at room temperature was elaborated in this paper. It is based on catalytic effect of silver ions upon the oxidation of methylene blue B (MBB) by K2S2O8 (PPS) in citric buffer (BUF) solution. The method was confirmed by determination of Ag(I) in PbO. The obtained results were compared t...

Ground coverage (GC) allows monitoring of crop growth and development is normally estimated as the ratio vegetation to total pixels from nadir images captured by visible-spectrum (RGB) cameras. The accuracy GC can be significantly impacted effect ‘mixed pixels’, which related spatial resolution imagery determined flight altitude, camera characteristics (fine vs coarse textures). In this study, ...

A new nitrocellulose-based solid-phase multiantigen immunoassay (MAIA) for the detection of serum antibodies to Streptococcus pneumoniae capsular polysaccharides (PPSs) is presented. Evaluation with human sera showed that the MAIA test is reproducible, sensitive, and specific. It correlated well with a conventional ELISA method. The multiantigen strip system allowed quantification of antibodies...

OBJECTIVE To obtain information on the socioeconomic, medical, and functional status of polio survivors, and to use these results as the preliminary data for establishing the middle-aged cohort of polio survivors. METHODS The subjects were recruited based on the medical records of multiple hospitals and centers. They were assessed through a structured questionnaire over the phone. Post-poliom...
