Most of these apomixis-linked GW4869 alleles showed nonsense and frameshift mutations, revealing

their probable pseudogene nature. None of the amplicons that were present only in specific stages of development of the apomictic flowers co-segregated with apomixis, indicating they did not originate from additional apomictic alleles but more probably from differential regulation of the same allele in apomictic and sexual flowers. The molecular functions inferred from sequence analysis of these latter amplicons were related to seed storage protein and regulatory genes of various types. The results are discussed regarding the possible role in apomictic reproduction of the differentially expressed genes in relation to their specificity of expression and inferred molecular functions.”
“A detailed investigation of the crystallographic damage has been carried out in GaN following 300 keV rare earth ion implantation at room temperature by varying the

fluence from 7 x 10(13) to 5 x 10(16) at/cm(2). It is shown that above a threshold fluence around 2 x 10(15) at/cm(2), nanocrystallization takes place from the surface, subsequent to the formation of a planar defects network consisting of basal and prismatic stacking faults. This network starts to form at the lowest analyzed fluence mostly around the mean projected range. When the fluence increases, it propagates toward the surface, reaching it just before the on-set of the nanocrystallization. A model based on the mechanical breakdown of the GaN wurtzite structure mediated by prismatic stacking faults is proposed. (C) 2011 American Institute of Physics. [doi:10.1063/1.3527944]“
“Hepatic 4SC-202 datasheet venous outflow obstruction (HVOO) is a rare complication after orthotopic liver transplantation (OLT) usually related to technical issues or to malposition or kinking of the hepatic graft. When HVOO www.selleckchem.com/products/bx-795.html is diagnosed during the early post-transplant period, surgical options are technically very demanding and outcomes discouraging. Therefore, angioplasty

and stent placement have been indicated to avoid a chronic lesion of the graft. Three cases of HVOO after OLT are reported. HVOO was diagnosed during the early post-transplant period and was due to graft malposition in two patients and kinking of the vena cava anastomosis in one. All patients were successfully treated with a 300-cc gel-filled breast implant surgically placed in the right hepatic fossa with the liver graft resting on it. Massive ascites in all three patients disappeared and renal impairment resolved within two wk post-implant placement. No prosthesis-related complications have been observed after a follow-up ranging from 30 to 58 months. We describe a simple and effective method of maintaining the liver graft in an adequate position to achieve prolonged relief of the outflow obstruction for the whole graft and discuss the advantages of a breast implant over stent placement or the use of different balloon catheters.
