Abstract

Magnetoelectroluminescence (MEL) of organic semiconductor has been experimentally tuned by adopting blended emitting layer consisting of both hole and electron transporting materials. A theoretical model considering intermolecular quantum correlation is proposed to demonstrate two fundamental issues: (1) two mechanisms, spin scattering and spin mixing, dominate the two different steps respectively in the process of the magnetic field modulated generation of exciton; (2) the hopping rate of carriers determines the intensity of MEL. Calculation successfully predicts the increase of singlet excitons in low field with little change of triplet exciton population., Comment: 16 pages, 4 figures

Abstract

Synchrotron radiation photoemission study showed that the energy level alignment at the interface between N, N'-bis(naphthalene-1-y1)-N, N'-bis(phenyl) benzidine (NPB), a typical hole transport material, and Al could be adjusted by precovering a thin C60 layer on Al. The interface dipoles so formed could shift both the highest occupied molecular orbital level of NPB and the secondary electron cutoff measured at the early stage of the NPB deposition. The barrier height for hole injection from Al to NPB could thus be lowered by as much as 0.98 eV, and the optimal thickness of the inserted C60 layer was found to be 8-12 Å. [ABSTRACT FROM AUTHOR]

Abstract

OBJECTIVE: To study the inflammatory factors in donor livers and its effect on recipient myocardial injury after liver transplantation recipients. PATIENTS AND METHODS: E ighteen p atients who underwent orthotopic liver transplantations between January 2014 and December 2015 in our hospital were selected. A portion of the hepatic venous blood of donor's livers was preserved in heparinized tubes after partial resection. The concentrations of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), cardiac troponin I (cTnI), creatine kinase isoenzyme (CK-MB), and the activity of lactate dehydrogenase (LDH) in serum were measured. The concentrations of TNF-α, IL-6, cTnI, and CK-MB, and the activity of LDH in serum from the central venous blood of recipients were measured at several time points. RESULTS: Persistent myocardial injuries were found in five patients, six experienced a transient increase of cardiac markers after surgery and returned to normal levels 24 h after surgery, and the others were normal. The comparison of the levels of inflammatory factors in serum between the five donors and recipients at different stages showed that the levels of myocardial markers of the donor livers which were supplied to the five cardiac injured patients were all significantly higher than those of other donor's livers, while the levels of serum inflammatory factors in recipients showed no changes during the T0-T2 stage but increased significantly during T3-T5 (p < 0.05). The cardiac function after surgery was significantly different from that before surgery and that of the recipients without myocardial injury (p < 0.05). CONCLUSIONS: Blood pressure changes before surgery may affect the levels of inflammatory factors in donor's liver and cause postoperative myocardial injury in recipients. Proper hypotensive therapy for donors before partial liver resection can prevent postoperative myocardial injury in recipients. [ABSTRACT FROM AUTHOR]

Abstract

The aim of this study was to investigate the effect of leukocyte filtration on the P-selectin (CD62P) surface expression of apheresis platelets during the retention period. Ten bags of apheresis platelets stored for 1 day (0-24 h) and 10 bags of apheresis platelets stored for 2 days (24-48 h) were used for leukocyte filtration (experimental group). Ten bags of apheresis platelets with the corresponding retention periods but without filtration were used as a negative control (control group). Thereafter, 100 μL of platelet suspensions from apheresis platelets with or without leukocyte filtration were sampled before and after leukocyte filtration for the detection of CD62P surface expression by flow cytometry. No statistical difference in the CD62P surface expression of apheresis platelets was observed before and after leukocyte filtration (P > 0.05), neither did the CD62P surface expression exhibit any change among the different retention periods. Leukocyte filtration does not affect the CD62P surface expression of apheresis platelets stored for up to 2 days, which indicates that leukocyte filtration does not damage the activation of apheresis platelets within the retention period.
