Nitrotoluenes are important intermediates in the chemical industry. 2,6-Dinitrotoluene (26DNT), 2,4-dinitrotoluene (24DNT) and 2-nitrotoluene are carcinogenic in animals and possibly carcinogenic in humans. It is therefore important to develop methods to biomonitor workers exposed to such chemicals. Hemoglobin (Hb) adducts of nitroarenes are established markers of the biological effective dose....

UNLABELLED The long-term protection of hepatitis B (HB) vaccination has been debated for years. The purpose here was to evaluate the kinetic changes of antibody to HB surface antigen (anti-HBs) and define immune memory of the HB vaccine among college students who had previously received full neonatal immunization against HB. In all, 127 college students aged 18-23 years born after July 1984 who...

Is O2 diffusivity within renal capillaries rate limiting for O2 delivery to hypoxic renal tubules? Equations based on diffusion theory and developed here predict that soluble hemoglobin (Hb) increases O2 diffusivity by a factor of 1 + [442 Hb%/(P50 +[Formula: see text])], where P50 is the partial pressure of O2 at which the Hb is half saturated. To examine the effect of P50 and Hb concentration...

Our recent studies on PEG-Hb [poly(ethylene glycol)-Hb] conjugates generated by thiolation-mediated maleimide-chemistry based PEGylation demonstrated that the vasoactivity of the PEG-Hb conjugates is a function of the configuration of the PEG chains on the surface of the protein and is independent of the PEG/protein-mass ratio [Manjula, A. G. Tsai, Intaglietta, H.-C. Tsai, Ho, Smith, Perumalsam...

BACKGROUND Patients with hemoglobin (Hb) variants may produce false HbA1c measurement. This study aimed to detect the common Hb variants in southern Taiwan and to evaluate their effect on the determination of HbA1c. METHODS A total of 1,434 samples collected for HbA1c measurement at Kaohsiung Veterans General Hospital in southern Taiwan in March 2008 were submitted for Hb variant analysis by ...

The HB problem first introduced by Blum and Hopper has been the basis for extremely lightweight authentication protocols for RFID tags [18, 19]. In this paper we introduce a variant of this problem which we call the strong HB problem. We analyze the strong HB problem and give some arguments that support its hardness. We then use the strong HB assumption in two applications of independent intere...

BACKGROUND In patients with COPD, chronic anemia is known as an unfavorable prognostic factor. Whether the association between hemoglobin (Hb) levels and long-term survival is restricted to anemia or extends to higher Hb levels has not yet been systematically assessed. METHODS We determined Hb levels in 309 subjects with COPD and chronic respiratory failure prior to initiation of noninvasive ...

A 19-year old Thai male presented to the hospital with fever, acute hemolysis, pallor and jaundice without hepatosplenomegaly. On admission his hematocrit was 17.4% and a blood smear showed moderate hypochromia with mild anisopoikilocytosis. Hemoglobin (Hb) electrophoresis revealed Hb A2ABart's Hb H with an abnormal band, which on PCR proved to be Hb Pyrgos (beta83, glycine --> aspartic acid). ...

The hB-pi tree is a multi-attribute index method which combines the hB tree, a multi-attribute access structure and the II-tree, an abstract index with efficient concurrency and recovery methods. The hB-pi tree is a balanced tree and adapts well to different data distributions. Furthermore, the hB-pi tree inherits the efficient concurrency and recovery methods from the II tree. This paper provi...

In this study, hyperbranched polymers were explored as matrix modifiers to create E-glass fiber (GF) reinforced polymer composites with enhanced mechanical properties. Hyperbranched have lower viscosities than their linear equivalents, potentially providing wet out leading improved stress transfer. (HB), hydrogenated (H-HB), and functional (LF) divinyl benzene blended polystyrene (LP) form a ra...
