At the onset of stationary phase, Bacillus subtilis secretes at least seven extracellular proteases of which subtilisin (aprE) and a neutral metalloprotease E (nprE) are the most abundant (6). Of the remaining five minor extracellular proteases, Epr (epr) contributes 2 to 4% to this pool (18). The expression of these enzymes is stringently regulated, as best exemplified by the aprE gene (23). H...
We have previously reported that the combination therapy of percutaneous ethanol injection and radiofrequency ablation (PEI-RFA) was more effective than RFA alone to induce wider coagulated necrosis for the treatment of hepatocellular carcinoma (HCC). In the present study, the effect of time-lag performance of RFA after PEI was evaluated under the same ablation condition as PEI-RFA by analyzing...
In the children’s game of rock, paper, scissors, players compete using 1 3 hand gestures, each with its own strengths and weaknesses: which crushes slash covers rock. Winning is temporary. After round, contest resumes. The provides a useful analogy for ongoing public relations (PR) battle over “surprise” billing medical claims, in publicity efforts by insurance companies, providers, patient adv...
Using the vector-wave multiple-scattering method we have calculated the photonic band structures of AB3 and B3 crystals composed of perfect metal spheres in air. It is shown that AB3 photonic crystal contains a large photonic band gap and B3 photonic crystal has more than one gap when the filling ratio of metal spheres exceeds a threshold. The multiple photonic gaps of the B3 structure are usef...
