The optical emission features were studied via temperature and excitation laser power dependent photoluminescence. Based on the photoluminescence and transmission electron microscopy observations, photoluminescence spectral features can be attributed to a bi-modal height distribution in certain samples. In order

to extend the optical emission to room temperature, the sample with 5 ML of InAs and an 8 nm spacer layer was subjected to post-growth rapid thermal annealing at different temperatures. The emission wavelength was tunable from 1.63 to 1.72 mu m at room temperature. (C) 2011 American Institute of Physics. [doi:10.1063/1.3598082]“
“A case of pulmonary blastomycosis in a pediatric patient diagnosed by gastric lavage is described. Use of gastric lavage averted the need for more invasive diagnostic techniques selleck chemicals including bronchoscopy. Further study is required to define the sensitivity of gastric lavage for recovery of Blastomyces dermatitidis from pediatric patients

with pulmonary blastomycosis.”
“Renal autotransplantation is a safe and effective procedure see more to reconstruct the urinary tract. The current indications for autotransplantation include renal vascular disease, severe ureteral damage, tumours of the kidney and ureter, complex nephrolithiasis and retroperitoneal fibrosis. We report a rare case where we had to perform renal autotransplantation along with hybrid surgery for aortic aneurysm repair. To our knowledge, this is the first case report of AZD1152 in vivo its kind for this specific condition. Copyright (c) 2012 S. Karger AG, Basel”
“Hydrothermal ZnO wafers implanted at room temperature with 60 keV Sn+ ions are examined by means of photoluminescence (PL), atomic force spectroscopy (AFM), and X-ray diffractometry techniques. The PL intensity significantly decreases in the wafers implanted to doses of 4.1 x 10(13) ions/cm(2) and higher. The AFM measurements indicate that surface roughness variation is not the cause of the significant decrease in PL intensity. Furthermore, the PL deep level (DL) band peak blueshifts after illuminating

the implanted samples with the He-Cd laser 325 nm line; meanwhile, the DL band intensity first increases and then decreases with illumination time. These abnormal behaviors of the DL band are discussed. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3598068]“
“We report herpes simplex encephalitis (HSE) in a toddler after a subtotal hemispherectomy for seizures related to HSE 16 months earlier. Herpes simplex virus reactivation in the cerebrospinal fluid shortly after treatment of HSE has been described, but is extremely rare in other situations. HSE reactivation is a potential complication of epilepsy surgery after HSE in children.”
“In this case report, we describe a severe arterial bleeding during transurethral resection of bladder cancer where routine endoscopic methods failed to stop the hemorrhage.
