The treatment of wastewater containing hypophosphite [P(I)] and phosphite [P(III)] is challenged by limitations of traditional Fenton oxidation such as low efficiency, secondary pollution and high costs. This study introduced a facile solvent-thermal method to synthesize Cu-CoO nanoparticles uniformly loaded on graphene (Cu-CoO/U-rGO) through the reduction and coordination effects of urushiol (U). As prepared Cu-CoO/U-rGO exhibited excellent activity in activating peroxymonosulfate (PMS) for the oxidation of P(I)/P(III) to phosphate [P(V)] (0.

However, efficient and metal-free methods for boosting the catalytic efficiencies of PILs are still challenging. In this study, a novel family of poly(ionic liquid)-coated carbon nanotube nanoarchitectures (CNTs@PIL) were facilely prepared via a noncovalent and in-situ polymerization method.

Background: Due to the significant differences in the medical and humanistic environment at home and abroad, the safety of patients during the transmission from intensive care unit to the general ward is often ignored when their conditions become stable. There are few qualitative studies on the cognition and practice on transitional care during the transfer from intensive care unit to the ward among health care professionals in China.
Aim: To explore the family caregivers' experiences and needs of transitional care during the transfer from an intensive care unit to a general ward in China.
Background: The transfer of patients from the intensive care unit to the ward is a vulnerable time for patients and caregivers, exposing the risk of readmission and death. However, there are few qualitative studies on the family caregivers' views of transitional care for their loved ones in China.
The integration of synergic hydrogen bond donors and nucleophilic anions that facilitates the ring-opening of epoxide is an effective way to develop an active catalyst for the cycloaddition of CO with epoxides. In this work, a new heterogeneous catalyst for the cycloaddition of epoxides and CO into cyclic carbonates based on dual hydroxyls-functionalized polymeric phosphonium bromide (PQPBr-2OH) was presented. Physicochemical characterizations suggested that PQPBr-2OH possessed large surface area, hierarchical pore structure, functional hydroxyl groups, and high density of active sites.

Growth curve, apoptosis assay, invasion assay and migration assay revealed that OPN status significantly affected proliferation, apoptosis, invasion and migration in gastric cancer cell lines. In mouse xenograft models of human gastric cancer, OPN silencing significantly inhibited tumor growth and the incidence of metastasis compared with non-silenced control.

Objective: To determine the basic characteristics and clinical manifestations of hospitalized patients with psoriasis in Hunan, and to provide reasonable reference for the etiology and treatment of psoriasis.
Methods: Totally 190 patients with psoriasis from January 1, 2012 to December 31, 2012 treated in the Department of Dermatology, the Second Affiliated Hospital of Central South University were retrospectively analyzed. The data were analyzed by SPSS17.
Multifunctional polymersomes loaded with maghemite nanoparticles and grafted with an antibody, directed against human endothelial receptor 2, are developed as novel MRI contrast agents for bone metastasis imaging. Upon administration in mice bearing bone tumor grown from human breast cancer cells, MR images show targeting and enhanced retention of antibody-labeled polymersomes at the tumor site.
