BACKGROUND A major risk factor for the development of surgical site infections is Staphylococcus aureus carriage. Compared with non-carriers, S. aureus carriers have up to a 14-fold greater risk for post-surgical infections. Pre-operative screening for S. aureus carriage is controversial. Yet, targeted screening in high-risk patients or from clinically relevant sites may be beneficial. We aimed...

Gastric cancer cell are not particularly sensitive to Ara-C, a deoxycytidine analog that affects DNA synthesis. In the present study, AGS and MKN-45 gastric cancer cell lines were treated with Ara-C to determine its role in cell prolife-ration and apoptosis. The antiproliferative effect of Ara-C was assessed using the Cell Counting kit-8. Gelatinase zymography was utilized to detect the activit...

We present optical spectroscopy of the host galaxies of 4 QSO’s: PG 1444+407, PKS 2349-147, 3C 323.1, and 4C 31.63 having a redshift range 0.1 ≤ z ≤ 0.3. The spectra were obtained at the Keck Observatory with the LRIS instrument offset 2-4 arcseconds from the nucleus at several position angles in each galaxy. The objects close to 3C 323.1 and PKS 2349-147 have the same redshifts of their nearby...

The proteasome is primarily responsible for the generation of MHC class I-restricted CTL epitopes. However, some epitopes, such as NP(147-155) of the influenza nucleoprotein (NP), are presented efficiently in the presence of proteasome inhibitors. The pathways used to generate such apparently "proteasome-independent" epitopes remain poorly defined. We have examined the generation of NP(147-155)...

We present optical spectroscopy of the host galaxies of four quasi-stellar objects (QSOs)—PG 1444 407, PKS 2349 147, 3C 323.1, and 4C 31.63—having a redshift range . The spectra were obtained at 0.1 ≤ z ≤ 0.3 the Keck Observatory with the Low Resolution Imaging Spectrograph instrument offset 2 –4 from the nucleus at several position angles in each galaxy. The objects close to 3C 323.1 and PKS 2...

NhaB is a bacterial Na(+)/H(+) antiporter with unique topology. The pH dependence of NhaB from Vibrio alginolyticus differs from that of the Escherichia coli NhaB homolog. Replacement of Asp-147 with Glu made high H(+) concentrations a requirement for the NhaB activity. Replacement of Asp-147 with neutral amino acids inactivated NhaB.
