A portable smartphone platform utilizing dual-sensing signals for visual determination of semicarbazide in food samples.

Semicarbazide (SEM) is a metabolite of antibiotic nitrofurazone and a food contaminant in food production, showing potential carcinogenic, mutagenic, teratogenic, and toxic effects on human health. It is urgent to develop a highly efficient and sensitive assay for visual detection of SEM. In this paper, a pyrrolopyrrole cyanine fluorescent probe (PPCy-1) was reported for visualization and quantitative analysis of SEM through a chromophore reaction sensing mechanism for the first time.

Recent Advances of Diketopyrrolopyrrole Derivatives in Cancer Therapy and Imaging Applications.

Cancer is threatening the survival of human beings all over the world. Phototherapy (including photothermal therapy (PTT) and photodynamic therapy (PDT)) and bioimaging are important tools for imaging-mediated cancer theranostics. Diketopyrrolopyrrole (DPP) dyes have received more attention due to their high thermal and photochemical stability, efficient reactive oxygen species (ROS) generation and thermal effects, easy functionalization, and tunable photophysical properties.

Influence of continuity of care on self-management ability and quality of life in outpatient maintenance hemodialysis patients.

Introduction: The objective of this study was to evaluate the effect of continuity of care on self-management ability and quality of life (QOL) in patients undergoing maintenance hemodialysis (MHD).

Methods: One hundred patients were randomly assigned to the observation group and the control group. In the observation group, patients received a 12-month continuity of care.

Low employment and low willingness of being reemployed in Chinese working-age maintained hemodialysis patients.

Aim: Returning to society plays an important role in improving the quality of life in maintenance hemodialysis (MHD) patients, and retention of employment is one of the core enablers. The study is to assess the employment status and to determine the variables for unemployment in Chinese MHD patients.

Methods: Prevalent MHD patients from four dialysis centers in Shanghai China were enrolled.
