Conclusions The lack of an association between sexual orientation and QOL suggests that if there is a link, it does not relate directly to clinical and demographic factors. Future studies need to identify areas of similarity and difference between sexual minority and heterosexual survivors and mechanisms to explain the similarity in QOL.”
“Two thin epitaxial GaAs films
on Ge substrates were characterized by photoluminescence (PL), contactless electroreflectance (CER), and piezoreflectance (PzR) techniques. The GaAs films containing antiphase domains (APDs) and those APD free were grown at 650 degrees C by metal organic vapor phase epitaxy. The PL intensity of the APD-containing film is four orders of magnitude lower than that of the APD-free sample. The reduction in intensity is due to the electrically active Ga-Ga and As-As bonds at the boundaries selleck products between the different APDs. buy CB-839 The electric fields deduced from Franz-Keldysh oscillations of the CER spectra were used to determine the net carrier concentration of the GaAs films. In addition, the conduction to light-hole band transitions and the conduction to heavy-hole band transitions that originated from strain induced valence band splitting in GaAs thin films were observed and identified through a comparison of the relative intensities of light-and heavy-hole related features in the PzR and CER
spectra. The results demonstrate that PL, CER, and PzR are useful nondestructive tools to characterize thin epitaxial GaAs films on Ge substrates. (c) 2009 American Institute of Physics. [DOI: 10.1063/1.3173282]“
“Pancreatic cancer is an extraordinarily deadly disease and is responsible for over 220,000 deaths worldwide each year. One of the greatest risk factors for developing pancreatic cancer is a positive family history. Hereditary
pancreatitis patients have a greatly elevated pancreatic cancer risk and individuals with cystic fibrosis may rarely develop this cancer, but often at very young ages. Various genetically linked cancer syndromes have been associated with pancreatic cancer in mutation-positive family members. Finally, familial pancreatic cancer-defined as families with two or more first-degree relatives who have pancreatic cancer but do not have a known cancer syndrome-is a selleck screening library known entity whose disease-causing mutation remains unidentified. This article describes research to date on hereditary pancreatic cancer, addresses how best clinicians should recognise hereditary forms of pancreatic cancer and explains the emotional burden of discovering a potentially lethal Mutation. Many controversies and unanswered questions in hereditary pancreatic cancer remain. (C) 2009 Elsevier Ltd. All rights reserved.”
