OBJECTIVE This is the first paper to evaluate the potency of the tuberculin skin test (TST) results in confirmed pulmonary tuberculosis in the developing country. METHOD Data was collected retrospectively from the tuberculosis (TB) treatment unit during the period from 1998 to 2004. All charts diagnosed as active tuberculosis based on positive sputum smear or culture with documented TST were ...

The explicit solvent simulations with MM and QM/MM are summarised in Table 1. The equilibrium (Eq.) simulations were carried out for 40 ns for MM and 20 ns for DFTB3/MM. Three independent FEP simulations were carried out for MM and QM/MM by taking the initial structures at 20 ns (A), 30 ns (B), and 40 ns (C) Eq. simulations for MM and 10 ns (A), 15 ns (B) and 20 ns (C) Eq. simulations for DFTB3...

Verapamil (10(-6) M) significantly reduced a development of the membrane depolarization and the contracture which were induced by Na removal. The fully developed depolarization, after exposure to Na-free solution, was reduced greatly by verapamil, excess Ca (15 mM) or sodium nitroprusside (10(-6) M), but some depolarization still remained. This remaining depolarization was completely blocked by...

Detailed analysis of the voltammetry of decamethylferrocene at micro and macrodisc electrodes has been carried out in scCO2/MeCN (15 wt%), 20 mM [NBu(n)4][BF4] and 309 K and 17.5 MPa. A passivating film needs to be removed from platinum electrodes before stable, reproducible voltammetry can be obtained. At low concentrations (0.22 mM) reversible 1e(-) behaviour is observed. Significant effects ...

Positron emission tomography (PET) scanners designed to image animals the size of rats and mice should possess simultaneously high and uniform spatial resolution and high sensitivity. ATLAS (Advanced Technology Laboratory Animal Scanner), a 6.0 cm diameter effective transverse field-of-view (FOV), 2 cm axial FOV ring-type research scanner seeks these goals by surrounding the animal with eightee...

OBJECTIVE To compare the effect of radio frequency ablation (RFA) on the dimensions of radio frequency coagulation necrosis in a rabbit lung using a wet electrode in monopolar mode with that in dual electrode bipolar mode at different infusion rates (15 mm/hr versus 30 ml/hr) and saline concentrations (0.9% normal versus 5.8% hypertonic saline). MATERIALS AND METHODS Fifty ablation zones (one...
