In the heating process, the Hy light scattering intensity started to decrease at low temperature far below the melting temperature while the ordering of the crystallites, estimated by the broadening of the light scattering profile, did not change up to the vicinity of the melting temperature. The decrease of the scattering intensity was steeper with increasing CO2 pressure and was thermally reversible. These results suggest that surface melting Lapatinib occurs in the crystallized PVDF under pressurized
CO2. The surface melting under CO2 might be attributed to the dragging of the crystalline chains by the amorphous chains in which the molecular motion is enhanced by the plasticization effect of CO2. Owing to the decrease of the lamellar thickness by the surface melting, the melting temperature depression occurred under pressurized CO2. (C) 2013 Elsevier Ltd. All rights reserved.”
“We present a case where we repaired the aortic arch, by the transposition of the left carotid artery to the ascending aorta. A 52-year-old man presented to our department with a penetrating chest wound by a gunshot in the attempt of suicide. The aortic arch and the insertion of the left
carotid artery were involved in the lesion. Through sternotomic approach, the aortic selleck chemicals arch was repaired in extracorporeal circulation. Left carotid artery was transected to allow easier repair of the arch posterior wall involved in the lesion, and to reduce the danger of residual stenosis. Then, it was translocated to the ascending aorta by interposing a 7-mm Gore-Tex (W.L. Gore & Associates, Flagstaff, AZ, USA) conduit. The patient complicated renal failure and pneumonia in the postoperative
period, but eventually he was discharged in good general conditions.\n\n(J Card Surg 2009;24:57-58).”
“The Buda Thermal Karst System is an active hypogenic karst area that offers possibility for the analysis of biogenic cave formation. The aim of the present study was to gain information about morphological structure and genetic diversity of bacterial communities inhabiting the Diana-Hygieia Thermal Spring (DHTS). Using scanning electron see more microscopy, metal accumulating and unusual reticulated filaments were detected in large numbers in the DHTS biofilm samples. The phyla Actinobacteria, Firmicutes and Proteobacteria were represented by both bacterial strains and molecular clones but phyla Acidobacteria, Chlorobi, Chlorofexi, Gemmatimonadetes, Nitrospirae and Thermotogae only by molecular clones which showed the highest similarity to uncultured clone sequences originating from different environmental sources. The biofilm bacterial community proved to be somewhat more diverse than that of the water sample and the distribution of the dominant bacterial clones was different between biofilm and water samples. The majority of biofilm clones was affiliated with Deltaproteobacteria and Nitrospirae while the largest group of water clones was related to Betaproteobacteria.
