Simple upper bounds for the spectral radius of an H-matrix and a block H-matrix are presented. They represent an improvement over the bounds in [T.Z. Huang, R.S. Ran, A simple estimation for the spectral radius of (block) H-matrices, Journal of Computational Applied Mathematics, 177 (2005), pp. 455–459].

A survey of 455 caregivers of children with severe emotional disorders identified four empirically distinct dimensions of collaboration between mental health professionals and the children's family members. Characteristics of families, professionals, and the service delivery process associated with the dimensions are examined, as is the relationship between collaboration and family satisfaction.

The Binax NOW Flu A enzyme immunochromatographic assay was compared to viral culture with R-Mix shell vials for 455 nasal-wash or nasal-aspirate specimens. The overall sensitivity, specificity, positive predictive value, and negative predictive value of the assay were 64.9%, 98.4%, 89.3%, and 93.2%, respectively. However, the assay sensitivity decreased significantly with increasing patient age.

Arenaviruses cause severe human disease ranging from aseptic meningitis following lymphocytic choriomeningitis virus (LCMV) infection to hemorrhagic fever syndromes following infection with Guanarito virus (GTOV), Junin virus (JUNV), Lassa virus (LASV), Machupo virus (MACV), Sabia virus (SABV), or Whitewater Arroyo virus (WWAV). Cellular immunity, chiefly the CD8(+) T-cell response, plays a cri...

Metabolic disorders and hypersensitivities affect tolerability and impact adherence to highly active antiretroviral therapy (HAART). The aim of this study was to determine the prevalence of C-482T/T-455C variants in the Apolipoprotein C3 (APOC3) promoter gene and Human leukocyte antigen (HLA)-B*57:01, known to impact lipid metabolic disorders and hypersensitivity respectively; and to correlate ...
