Conclusions: The heavy reliance on informal routes of communication and integration by patients and providers emphasizes the urgent need for change in order to improve coordinating mechanisms for hospital community oncologic care. (C) 2013 Elsevier Ltd. All rights reserved.”
“Ovary is located inside peritoneal cavity. However, a huge malignant ovarian tumor CA3 solubility dmso may get involved with retroperitoneal structures.

We reported a case of a 70-year-old woman presented with a 2-month history

of increased abdominal distention and was subsequently found to have a giant abdominal mass. A huge low signal intensity mass with the involvement of retroperitoneal structures was showed on MRI. At operation, we found that the tumor pushed mesentery and small bowel upwards with the encasement of 10 cm jejunum and was fixed posteriorly to vena cava, aorta, right iliac Bcl-2 inhibitor vessels, and right

ureter. It was dissected from the retroperitoneal structures and resected en bloc with the involved jejunum.

Although ovary is located inside peritoneal cavity, a huge malignant ovarian tumor may get involved with retroperitoneal structures. So, great care should be taken not to injury the retroperitoneal structures as vena cava, mesenteric vessels, iliac vessels, and ureters.”
“High-strength and high-toughness nanofibers were made from polyimide 6F-PI through PRT062607 purchase electrospinning. The 6F-PI had a backbone made up with 3,3′,4, 4′-biphenyl-tetracarboxylic dianhydride and 2,2-bis[4-(4-aminophenoxy)phenyl]-hexafluoro-propane residues. Electrospun 6F-PI precursor nanofibers were collected in the form of aligned fiber sheet on the rim of a rotating disc. Heating process converted the precursor fiber sheets to 6F-PI nanofiber sheets. Gel permeation chromatography and Ostwald Viscometer were used to determine the molecular weight and the molecular weight distribution of the 6F-PI precursor, i.e., the 6F-polyamic acid. Scanning electron microscopy, infrared spectroscopy, X-ray scattering, tensile testing, dynamic mechanical analysis, thermogravimetric

analysis, and differential scanning calorimetry were employed to characterize the surface morphology, thermal stability, and mechanical properties of the 6F-PI nanofiber sheets. Experimental results show that the nanofibers were well aligned in the sheets with fiber diameters ranging from 50 to 300 nm. The nanofiber sheets were stable to over 450 degrees C, with a glass transition at 265.2 degrees C. The uniaxial tension test showed that the 6F-PI nanofiber sheets had superior mechanical properties. The ultimate tensile strength, modulus, toughness, and elongation to break of the 6F-PI nanofiber sheets are respectively, 308 +/- 14 MPa, 2.08 +/- 0.25 GPa, 365 +/- 20 MPa, and 202 +/- 7%.
