Organohalogen contaminants in humans with emphasis on polybrominated diphenyl ethers
(2002-02-08)
for the analysis of PBDEs and hydroxylated metabolites of polychlorinated biphenyls (OH-PCBs) in breast milk, matemal and cord blood plasma, liver and adipose tissue.
PBDEs and PCBs were found in all samples. The PCB levels were approximately 100 times higher...
Management of Helicobacter pylori infection in Vietnam
(2004-05-07)
.1 % were still H. pylori positive and 58.7% were free from peptic ulcer after one year. ELISA based on Vietnamese antigens showed a specificity of 96.4% and sensitivity of 91.0% compared to 96.4% and 69.4%, respectively, when Swedish antigens were used...
Regeneration of the antioxidant ubiquinol by flavoenzymes and the role of antioxidant defence in experimental hepatocarcinogenesis
(2002-05-24)
demonstrated that 90% of the activity was in the protein fraction with a molecular weight of above 100 kDa. The properties of the reaction was similar with those of thioredoxin reductase suggesting that this enzyme is the one mainly responsible...
Pulmonary embolism : validation of diagnostic imaging methods in the clinical setting
(2002-09-20)
Pulmonary embolism (PE) is an elusive diagnosis and none of the existing imaging modalities have a 100% diagnostic specificity or sensitivity. Pulmonary arteriography (PA) is the most specific test although the improvement of computed tomography...
Cryptic chromosome abnormalities in idiopathic mental retardation
(2001-12-21)
factors, members of a gene family involved in embryonic development of different tissues, body axis and midline structures. The size of the terminal 22q deletion was estimated to 100 kb, and three genes were affected by the deletion. ProSAP2, expressed...
The uterine proteoglycan expression in pregnancy and labor
(2004-02-26)
concentration increased by 46% during active labor. Identification of heparan sulphate proteoglycans revealed the presence of syndecan 1-4, glypican 1 and perlecan. Syndecan 3 is the most abundant heparan sulphate proteoglycan in human uterus and show the most...
Toxin production in clostridium difficile
(2004-05-20)
the induction of the toxin yields in C. difficile by 100 to 1000-fold. Glucose also lowered toxin synthesis and furthermore, reduced the uptake and metabolism of certain amino acids. When toxin synthesis was already initiated amino acids stopped toxin synthesis...
Mass spectrometry in the search for new drugs of abuse : method development and clinical application
(2004-02-27)
direct injection of urine and liquid chromatography-tandem mass
spectrometry. The final application included 23 analytes, covering
phenylethylamines, nonbenzodiazepine hypnotics and Nbenzylpiperazine and
had a capacity of analysing -100 samples per 24...
HIV-1 infection in Tanzania : HIV antibody testing strategies and lymphocyte subset determinations
(2003-04-16)
. Serocard followed by Determine gave a specificity of 99.3%. A testing strategy with 100% specificity (95% Cl; 99.6- 100%) could be achieved by the sequential use of all three simple/ rapid assays or by repeat testing by Capillus followed by Serocard...
Genetic differences in neuropathy and opioid responses in rats
(2003-11-28)
The studies examined mechanisms and treatments of experimental neuropathic pain with particular emphasis on the differences between rat strains and sub-strains in basal nociceptive sensitivity, development of neuropathic ...
