a case of palmoplantar hyperkeratosis with periodontosis and a history of recurrent severe pyoderma, pneumonia and multiple liver abscesses is described in a 12 year old girl. the patient demonstrated neutrophil dysfunction characterized by decreased random migration and chemotaxis and defective bactericidal activity. the exact immunopathological mechanism for susceptibility to infections in pa...

Helicobacter pylori (HP)-eradication therapy increases Runt domain transcription factor 3 (RUNX3) expression in the glandular epithelial cells in enlarged-fold gastritis. The aim of this study is to evaluate expression of the RUNX3 protein, the product of a gastric tumor suppression gene, and mutagenic oxidative stress in human gastric mucosal specimens obtained from patients with HP-induced en...

BACKGROUND This study was conducted to elucidate if nitric oxide is released by the porcine jejunal mucosa upon selective stimulation of AT2 receptors and the possible involvement of iNOS, and to investigate the presence of jejunal AT1 and AT2 receptors. Young landrace pigs were anaesthetized with ketamine and alpha-chloralose. Jejunal luminal NO output was assessed by intraluminal tonometry an...

The dynamics of detonation transmission from a straight channel into curved chamber was investigated numerically and experimentally as function initial pressure (10 kPa ? p0 26 kPa) in an argon diluted stoichiometric H2–O2 mixture. Numerical simulations considered the two-dimensional reactive Euler equations with detailed chemistry; hi-speed schlieren OH* chemiluminescense were used for flow vi...

Vertical polyacrylamide gel electrophoresis (PAGE) is routinely used in molecular biology to separate macromolecules. DNA sequencing, singlestranded conformational polymorphism (SSCP) analysis and microsatellite typing all utilize the high resolution capabilities of polyacrylamide gels to separate molecules that differ in size by as little as one base pair. However, preparation of these gels is...

A rapid, senstive method for NO2 analysis utilizing the chemiluminescence reaction of NO and O3 is provided by the use of the Scott Model 125 Chemiluminescense NO/NOI, Analyzer. Measurement of NO2 in the air sample by reducing it to NO by passage tgrough a converter before it enters the reaction chamber. Thermal converter will also convert, partially or completly, NH3 (and other N-componds) dep...
