Oxidative injury to hemoglobin (Hb) leads to formation of methemoglobin (MetHb), reversible hemichromes (rHCRs), and irreversible hemichromes (iHCRs). iHCRs precipitate and form Heinz bodies that attach to the red cell membrane causing injury that leads to hemolysis. The molecular mechanisms of this membrane damage have not been fully elucidated. We have studied the effect of Hb oxidation produ...

Benthic microbial communities contribute to nitrogen (N) cycling in coastal ecosystems through taxon-specific processes such as anammox, nitrification and N-fixation community attributed pathways denitrification. By measuring the total (DNA-based) active (RNA-based) surface sediment composition abundance activity profiles of key N-cycling genes a semi-enclosed embayment—Port Phillip Bay (PPB), ...

HB and HB+ are a shared secret-key authentication protocols designed for low-cost devices such as RFID tags. HB+ was proposed by Juels and Weis at Crypto 2005. The security of the protocols relies on the learning parity with noise (LPN) problem, which was proven to be NP-hard. The best known attack on LPN by Levieil and Fouque [13] requires subexponential number of samples and sub-exponential n...

We report a new potentiometric method for determining pyruvate kinase (PK). Enzymatic activity is measured by monitoring the change in pH produced in the reaction buffer under International Committee for Standardization in Haematology (ICSH) standardized assay conditions, and the lactate dehydrogenase reaction is automatically subtracted in each measuring cycle. The analysis, performed at 37 de...

Ferula persica, is the well-known species of the genus Ferula in Iran and has two varieties: persica and latisecta. They have both been extensively used in traditional medicine for a wide range of ailments. A great number of chemical compounds including sesquiterpene coumarins and polysulfides have been isolated from this plant. Fresh plant materials, crude extracts and isolated components of F...

We assessed the effects of in vivo phototherapy of Gunn rats on the activity of hepatic microsomal mixed-function monoxygenases and on the in vivo pharmacokinetics of [14C]HB. In experiment 1 no serial changes were seen in activities of hexobarbital hydroxylase or benzo(a)pyrene hydroxylase in hepatic microsomes isolated after 2, 4 or 7 days from homozygous jaundiced female Gunn rats exposed to...

The present study aimed to identify serum biomarkers for the detection of hepatoblastoma (HB). Serum samples were collected from 71 HB patients (stage I, n = 19; stage II, n = 19, stage III, n = 19; and stage IV, n = 14) and 23 age- and sex-matched healthy children. Differential expression of serum protein markers were screened using surface-enhanced laser desorption/ionization time-of-flight m...

Previous studies suggested that y87 Gln in hemoglobin (Hb) F is an important site for promoting inhibition of Hb S (cy#: polymerization by H b F. We engineered and isolated the double mutant ) using a yeast expression system and characterized polymerization properties of this modified tetramer in an effort to clarify the role of Gln at position 87 in inhibiting H b S polymerization. Electrop...
