Abstract

To explore the synergic effect of the combination of mirror therapy and electrical stimulation on lower limb motor function recovery in stroke survivors.PubMed, Web of Science, Embase, Cochrane Library, CINAHL, CNKI, Wan Fang, CBM were searched from inception to December 2020. Randomized controlled trials that compared the combined therapy with another single therapy were included. A pre-determined data collection form was used to extract data. Two authors independently extracted data and used the Cochrane Handbook criteria to assess the quality of included studies.Six studies, with a total of 437 patients were included. There was an overall positive effect on lower limb motor function recovery, according to Fugl-Meyer Assessment for the Lower Extremity [all: WMD in fixed effects model: 5.63, 95% CI 4.86, 6.39] and Brunnstrom stage [all: WMD in fixed effects model: 0.49, 95% CI 0.32, 0.66].The results indicate that the combination of mirror therapy and electrical stimulation for lower extremity motor function recovery in stroke survivors may have a positive effect.

Abstract

Developing red thermally activated delayed fluorescence (TADF) emitters for high‐performance OLEDs is still facing great challenge. Herein, three red TADF emitters, pDBBPZ‐DPXZ, pDTBPZ‐DPXZ, and oDTBPZ‐DPXZ, are designed and synthesized with same donor–acceptor (D‐A) backbone with different peripheral groups attaching on the A moieties. Their lowest triplet states change from locally excited to charge transfer character leading to significantly enhance reverse intersystem crossing process. In particular, oDTBPZ‐DPXZ exhibits efficient TADF feature and exciton utilization. It not only achieves an external quantum efficiency (EQE) of 20.1 % in red vacuum‐processed OLED, but also realize a high EQE of 18.5 % in a solution‐processed OLED, which is among the best results in solution‐processed red TADF OLEDs. This work provides an effective strategy for designing red TADF molecules by managing energy level alignments to facilitate the up‐conversion process and thus enhance exciton harvesting.

Abstract

Rational manipulation of energy utilization from excited-state radiation of theranostic agents with a donor-acceptor structure is relatively unexplored. Herein, we present an effective strategy to tune the exciton dynamics of radiative excited state decay for augmenting two-photon nanotheranostics. As a proof of concept, two thermally activated delayed fluorescence (TADF) molecules with different electron-donating segments are engineered, which possess donor-acceptor structures and strong emissions in the deep-red region with aggregation-induced emission characteristics. Molecular simulations demonstrate that change of the electron-donating sections could effectively regulate the singlet-triplet energy gap and oscillator strength, which promises efficient energy flow. A two-photon laser with great permeability is used to excite TADF NPs to perform as theranostic agents with singlet oxygen generation and fluorescence imaging. These unique performances enable the proposed TADF emitters to exhibit tailored balances between two-photon singlet oxygen generation and fluorescence emission. This result demonstrates that TADF emitters can be rationally designed as superior candidates for nanotheranostic agents by the custom controlling exciton dynamics., Competing Interests: The authors declare no conflict of interest., (This journal is © The Royal Society of Chemistry.)
