In the 46 recipients of left lobe grafts, three developed outflow block (6.5%).
Conclusions: The middle and left hepatic veins tend to distort and stretch during graft regeneration. These characteristics seem to be associated with outflow disturbances.”
“A selleck chemicals llc silicon dioxide (SiO(2)) electret passivates the surface of crystalline silicon (Si) in two ways: (i) when annealed and hydrogenated, the SiO(2)-Si interface has a
low density of interface states, offering few energy levels through which electrons and holes can recombine; and (ii) the electret’s quasipermanent charge repels carriers of the same polarity, preventing most from reaching the SiO(2)-Si interface and thereby limiting interface recombination. In this work, we engineer a charged thermal SiO(2) electret on Si by depositing corona charge onto the surface of an oxide-coated Si wafer and subjecting the wafer to a rapid thermal anneal (RTA). We show that the surface-located corona charge is redistributed deeper into
the oxide by the RTA. With 80 s of charging, and an RTA at 380 degrees C for 60 s, we measure an electret charge density of 5 x 10(12) cm(-2), above Mizoribine which no further benefit to surface passivation is attained. The procedure leads to a surface recombination velocity of less than 20 cm/s on 1 Omega-cm n-type Si, which is commensurate with the best passivation schemes employed on high-efficiency Si solar cells. In this paper, we introduce the method of SiO(2) electret formation, analyze the relationship between charge density and interface recombination, and assess the redistribution of charge by the RTA.

“Background: selleck The development of vaccines against pandemic influenza viruses for use in children is a public health priority.
Methods: In this phase II, randomized, open study, the immunogenicity and reactogenicity of H5N1 A/Vietnam/1194/2004 (NIBRG-14) (clade 1) prepandemic influenza vaccine were assessed in children aged 3 to 5 and 6 to 9 years. Children were randomized to receive 2 doses, given 21 days apart, of A/Vietnam/1194/2004 vaccine containing 1.9 mu g or 3.75 mu g hemagglutinin antigen (HA), adjuvanted with a tocopherol-based oil-in-water emulsion (AS03) containing 11.86 mg (AS03(A)) or 5.93 mg (AS03(B)) tocopherol. Control groups received 2 doses of trivalent influenza vaccine (TIV). Humoral immune responses, reactogenicity, and safety were the primary outcome measures; cross-reactivity and cell-mediated responses were also assessed (NCT00502593).
Results: Between 49 and 51 children in each age stratum (aged 3-5 and 6-9 years) received H5N1 vaccine, and between 17 and 18 children in each age stratum received TIV. After the second dose, recipients of H5N1 vaccine (1.9 mu g HA/AS03(B), 3.75 mu g HA/AS03(B), and 3.75 mu g HA/AS03(A)) achieved humoral antibody titers against the vaccine-homologous strain, which fulfilled the United States influenza vaccines licensure criteria for immunogenicity.
