The photoluminescent properties of one-dimensional LaPO4:Eu nanowires were studied in contrast with the corresponding zero-dimensional nanoparticles, micrometer particles, and micrometer rods. The results indicate that in nanowires Eu3+ ions occupied two different symmetry sites, unlike in nanoparticles and micrometer particles. Furthermore, the radiative(More)
Oxidative stress has been considered as the possible mechanism of renal ischemia/reperfusion injury. L-carnitine is an endogenous mitochondrial membrane compound and could effectively protect ischemia-reperfusion injury in the kidney. To elucidate the nephroprotective effects of L-carnitine, here we assessed the effect of L-carnitine on hydrogen peroxide(More)
Chronic granulomatous disease (CGD) is a group of inherited disorders in which phagocytes are unable to generate superoxide (O2) due to genetic defects in any 1 of 4 essential NADPH oxidase components. Mutations in the X-linked gene for gp91phox, the large subunit of the flavocytochrome b558 heterodimer, account for the majority of CGD. An X-CGD patient in(More)
In this paper, the upconversion luminescent properties of Gd2O3:Er3+,Yb3+ nanowires as a function of Yb concentration and excitation power were studied under 978-nm excitation. The results indicated that the relative intensity of the red emission (4F(9/2)-4I(15/2)) increased with increasing the Yb3+ concentration, while that of the green emission(More)
One-dimensional pure cubic Y(2)O(3)/Eu(3+) nanocrystals (NCs) were synthesized by a hydrothermal method at various temperatures. The NCs prepared at 130 degrees C yielded nanotubes (NTs) with wall thickness of 5-10 nm and outer diameter of 20-40 nm. The NCs prepared at 170 and 180 degrees C yielded nanowires (NWs) with diameters of approximately 100 and(More)
BACKGROUND Molecular adsorbents recirculating system (MARS) liver support therapy is the development of albumin dialysis. This study was to assess the successful application of MARS artificial liver support therapy as a bridge to re-transplantation in two cases of long anhepatic duration. METHODS MARS therapy was given after failure plasma-exchange (PE)(More)
OBJECTIVE To explore the etiopathogenesis, therapy and incidence of pulmonary infection in kidney transplantation recipients taking new immunosuppressant. METHODS The clinical data from 752 kidney transplant recipients were retrospectively analyzed, who were divided into 3 groups according to the immunosuppressants administered, namely group A(More)
OBJECTIVE To investigate the effect of trichostatin A (TSA) on proliferation and interleukin-2 (IL-2) expression of mouse T cells in mixed lymphocyte culture (MLC), and explore its effect on T cell-mediated immune response. METHODS BALB/c and C57BL mouse MLC was treated with different concentrations of TSA for different durations, and the lymphocyte(More)
OBJECTIVE To investigate the effect of anti-tumor necrosis factor-alpha monoclonal antibody (anti-TNF-alpha mAb) in alleviating renal ischemia-reperfusion injury. METHODS Fifty normal male Sprague-Dawley rats were randomly divided into 3 groups, namely group A that was subjected to ischemia-reperfusion injury with intravenous administration of(More)
This note examines the day-of-the-week effect in Australian daily stock returns at the market and industry levels and for small capitalization stocks from Monday 9 September 1996 to Friday 10 November 2006. A regression-based approach is employed. The results indicate that while the Australian market overall provides no evidence of daily seasonality, there(More)
