CD71-mediated liposomal arsenic-nickel complex combined with all-trans retinoic acid for the efficacy of acute promyelocytic leukemia.

Clinically, arsenic trioxide (ATO) was applied to the treatment of acute promyelocytic leukemia (APL) as a reliable and effective frontline drug. However, the administration regimen of As was limited due to its fast clearance, short therapeutic window and toxicity as well. Based on CD71 overexpressed on APL cells, in present study, a transferrin (Tf)-modified liposome (LP) was established firstly to encapsulate As in arsenic-nickel complex by nickel acetate gradient method.

Recent Advances in Perfluorocarbon-Based Delivery Systems for Cancer Theranostics.

Hypoxia is a key impediment encountered in the treatment of most solid tumors, leading to immune escape and therapeutic resistance. Perfluorocarbons (PFCs) have a unique electrical structure and are characterized by a high solubility for gases. PFC-based oxygen carriers have been evaluated for their ability to deliver oxygen effectively to hypoxic tissues, and significant clinical translation has been demonstrated.

Tumor-permeable smart liposomes by modulating the tumor microenvironment to improve the chemotherapy.

Low levels of accumulation and permeability in tumors are two primary reasons for the limited efficacy of conventional antineoplastic nanodrugs. In the present study, based on an original corosolic acid liposome (CALP) carrier with the functions of cell penetration, tumor permeability and anti-inflammation developed by our previous work, a versatile PTX/CALP was achieved by CALP loading paclitaxel (PTX). Compared to conventional PTX liposomes (PTX/LP) prepared by cholesterol and phospholipid, PTX/CALP exhibited extremely increasing cellular uptake and cytotoxicity in vitro, and in vivo enhancing the accumulation and permeability of tumor, thus significantly improving the antitumor efficacy.

Graphdiyne-supported single-cluster electrocatalysts for highly efficient carbon dioxide reduction reaction.

The electrochemical CO reduction reaction (CORR) has become a promising technology to resolve globally accelerating CO emissions and produce chemical fuels. In this work, the electrocatalytic performance of transition metal (TM = Cu, Cr, Mn, Co, Ni, Mo, Pt, Rh, Ru and V) triatomic clusters embedded in a graphdiyne (GDY) monolayer (TM@GDY) for CORR is investigated by density functional theory (DFT) calculations. The results indicate that Cr@GDY possesses the best catalytic performance with a remarkably low rate-limiting step of 0.

A practical strategy to subcutaneous administered gelling co-delivery system of arsenic and retinoic acid for the treatment of acute promyelocytic leukemia.

Arsenic trioxide (ATO) combined with all trans retinoic acid (ATRA) is the first choice for the treatment of low and medium risk acute promyelocytic leukemia (APL). Clinical studies reported that the combination of ATO and ATRA could achieve a significant curative effect. However, the retinoic acid syndrome, serious drug resistance and the short half-life which lead to frequent and large dose administration limit the application of ATRA.

Giant magnetic moment of the core-shell Co13@Mn20 clusters: first-principles calculations.

The core-shell clusters Co(13)@TM(20) with TM = Mn, Fe, Co, and Ni are investigated within first-principles simulations in the framework of density-functional theory. Huge magnetic moments have been found in the Co(13)@TM(20) clusters especially for the Co(13)@Mn(20) cluster with a giant magnetic moment of 113 μ(B). The large magnetic moments are mainly due to the special core-shell structure and the weak interaction between the TM and other atoms.

Characteristics associated with falls among the elderly within aged care wards in a tertiary hospital: a retrospective.

Background: Falls are the most frequently reported adverse events in inpatient settings. We conducted a retrospective case-control study of inpatient falls within aged care wards in a tertiary hospital to investigate the associated characteristics of elderly patients suffering from falls and fall-related characteristics.

Methods: Consecutive retrospective cross-sectional design spanned July 2006 to December 2008.
