Ubiquitin-specific protease 22 (USP22), a novel ubiquitin hydrolase, has been implicated in oncogenesis and cancer progression in various types of human cancer. However, the clinical significance of USP22 expression in non-small cell lung cancer (NSCLC) has not been determined. In the present study, USP22 messenger RNA (mRNA) and protein levels were(More)
In this note, we will discuss two aspects of brane-antibrane forces. In one aspect, we generalize the force calculation of D0-¯ D0 of Banks and Susskind to Dp-¯ Dp for 1 ≤ p ≤ 8. In particular, we find that the force is also divergent for p = 1 while for the other cases (p ≥ 2) the forces are in general finite when Z → 0 + , where Z = Y 2 2π 2 α ′ − 1 with(More)
Nocardia are aerobic Gram-positive saprophytes that are widely distributed in nature, but some species cause nocardiosis, especially opportunistic infections that affect immunocompromised patients mostly. In this study, we developed a multilocus sequence typing (MLST) scheme using seven housekeeping genes (gyrB, hsp65, secA1, rpoB, rpoA, recA, and trpB) for(More)
PURPOSE To explore the association between the 3,144 m/z protein peak and the clinicopathological features and prognosis in breast cancer. METHODS Using SELDI-TOF MS, we analyzed serum protein peak at 3,144 m/z in 283 patients with node-positive breast cancer, its relationship with clinicopathological features and their prognosis evaluating value of(More)
AlGaN/GaN high electron mobility transistors (HEMTs) were exposed to 3 MeV protons at fluences of 6 Â 10 13 , 4 Â 10 14 and 1 Â 10 15 protons/cm 2. The drain saturation currents decreased by 20% and the maximum transconductance decreased by 5% at the highest fluence. As the fluence increased, the threshold voltage shifted more positive values. After proton(More)
