Factors Contributing to Success in Nursing School: Experiences of African American BSN Students.

The nursing workforce is not keeping pace with the racial demographics in the United States. In addition, attrition rates for ethnic minorities in schools of nursing remain high. This qualitative study examined African American students' perceptions of factors that affect successful completion of nursing school.

Fluence-induced reversal of saturable absorption in a ruthenium-based porphyrin.

Experimental nonlinear absorption data obtained using the open-aperture Z-scan technique are presented for 2, 3, 7, 8, 12, 17, 18-octaethyl-21H, 23H-porphine ruthenium (II) carbonyl in tetrahydrofuran. These data show saturation of nonlinear absorption dominating at low fluence but being overcome by induced absorption (reverse saturable absorption) at high fluence. Large-angle scattering measurements demonstrate that the induced absorption is real and not merely the result of scattering of light outside of the collection aperture of the detector by scattering centers induced at high fluence.

Cytologic persistence of malignant cells after transurethral resection of bladder tumors: Implications for concomitant manipulation of the urinary tract at the time of endoscopic resection.

Background: The current study was conducted to determine the feasibility of cytologically clearing the bladder of tumor cells after transurethral resection of bladder tumor (TURBT) and aggressive serial bladder washing.

Methods: A prospective pilot sample of 20 patients with known bladder masses was enrolled before undergoing TURBT. Preoperative cytology and 4 postoperative cytology specimens were assessed for malignant cells between serial bladder washes.

Strong triplet excited-state absorption in a phenanthrolinyl iridium(III) complex with benzothiazolylfluorenyl-substituted ligands.

Femtosecond transient difference absorption (fs TA) measurements, together with a series of open-aperture Z scans at picosecond and nanosecond pulse widths and a variety of pulse energies, were performed on a 1,10-phenanthrolinyl iridium(III) complex bearing ligands containing a benzothiazolylfluorenyl motif. An analysis of decay data from the fs TA experiment yields a value of 1.24±0.

Conditional inactivation of the mouse von Hippel-Lindau tumor suppressor gene results in wide-spread hyperplastic, inflammatory and fibrotic lesions in the kidney.

Mutations of the tumor suppressor gene von Hippel-Lindau (VHL) can lead to benign and malignant tumors, including clear-cell renal cell carcinoma (ccRCC). To understand the progression of ccRCC, we generated a novel mouse Vhlh conditional knockout, using Hoxb7-driven Cre that is specific for the collecting ducts and a subset of distal tubules. These mice exhibited wide-spread epithelial disruption and interstitial inflammation as early as 2 months of age with high penetrance.
