Liver transplantation across ABO blood groups [PDF]

open access: yes, 1986
Six hundred seventy-one first, second, and third orthotopic liver allografts in 520 patients were reviewed to determine the effect of donor-recipient mismatches or incompatibility for the ABO blood group on graft survival. A significant advantage for ABO

Cluster Abell 520: a perspective based on member galaxies. A cluster forming at the crossing of three filaments?

open access: yes, 2008
The connection of cluster mergers with the presence of extended, diffuse radio sources in galaxy clusters is still debated. An interesting case is the rich, merging cluster Abell 520, containing a radio halo.

Endovascular treatment for ureterorectal-arterial fistula and external iliac artery stenosis caused by recurrent endometrial cancer invasion: A case report

open access: yesRadiology Case Reports
Owing to improvements in anticancer treatment, patients’ overall survival has been prolonged, and late complications occur more frequently than previously. We successfully managed a case of ureterorectal-arterial fistula (URAF) and external iliac artery (

Fabrication of 5-20 nm thick β-W films

open access: yesAIP Advances, 2014
A technique to fabricate 5 to 20 nm thick sputter deposited β W films on SiO2 and Si substrates is presented. This is achieved by growing tungsten on a 5 nm SiO2 layer or in an oxygen controlled environment by flowing 2 sccm of O2 during deposition ...

MicroRNA-520/373 family functions as a tumor suppressor in estrogen receptor negative breast cancer by targeting NF-κB and TGF-β signaling pathways

open access: yesOncogene, 2012
MicroRNAs (miRNAs) as modulators of gene expression have been described to display both tumor-promoting and tumor-suppressive functions. Although their role has been studied in different tumor types, little is known about how they regulate nuclear factor

Defect‐Free Block Copolymer‐Based Distributed Bragg Reflector for Optimized Light Harvesting in BiVO4 Photoanodes

open access: yesAdvanced Functional Materials, EarlyView.
A solution‐processed distributed Bragg reflector (DBR) film, integrated via block copolymer (BCP) self‐assembly, enhances photon recycling in BiVO4 photoanodes for improved photoelectrochemical (PEC) performance. By tuning lamellar structures using lactic acid and cross‐linking density, the DBR film optimally shifts working wavelengths, boosting ...

A non-commutative algorithm for multiplying (7 $\times$ 7) matrices using 250 multiplications

open access: yes, 2017
We present a non-commutative algorithm for multiplying (7x7) matrices using 250 multiplications and a non-commutative algorithm for multiplying (9x9) matrices using 520 multiplications.

Controlled Aggregation of Pyrene‐Based Supramolecular Nanostructures for Light‐Driven Switchable H2 or H2O2 Production

open access: yesAdvanced Functional Materials, EarlyView.
This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

Occupational Safety and Health (OSH) management systems: towards development of safety and health culture [PDF]

open access: yes, 2006
The unsatisfactory OSH record of the construction industry has always been highlighted. It is because the OSH management system is a neglected area and a function that has not been pursued systematically in the construction industry.
