Comparative efficacy and safety of first-line tyrosine kinase inhibitors in chronic myeloid leukemia: a systematic review and network meta-analysis.

Background: Tyrosine kinase inhibitors (TKIs) have become the preferred drugs for the treatment of chronic phase (CP) chronic myeloid leukemia (CML). This study aims to compare the safety and efficacy of different TKIs as first-line treatments for CML using network meta-analysis (NMA), providing a basis for the precise clinical use of TKIs.

Methods: A systematic search was conducted on PubMed, Cochrane Library, Embase, China National knowledge Infrastructure (CNKI), Wanfang, Chinese Science and Technology Periodical Databases (VIP), SinoMed and ClinicalTrials.

Multiple Interlayer Interactions Enable Highly Stable X-ray Detection in 2D Hybrid Perovskites.

Metal halide perovskites have outperformed conventional inorganic semiconductors in direct X-ray detection due to their ease of synthesis and intriguing photoelectric properties. However, the operational instability caused by severe ion migration under a high external electric field is still a big concern for the practical application of perovskite detectors. Here, we report a 2D (BPEA)PbI (BPEA = -1-(4-bromophenyl)ethylammonium) perovskite with Br-substituted aromatic spacer capable of introducing abundant interactions, e.

Tetrandrine alleviates oxaliplatin-induced mechanical allodynia via modulation of inflammation-related genes.

Oxaliplatin, a platinum-based chemotherapy drug, causes neuropathic pain, yet effective pharmacological treatments are lacking. Previously, we showed that tetrandrine (TET), with anti-inflammatory properties, reduces mechanical allodynia in nerve-injured mice. This study explores the effect of TET on oxaliplatin-induced mechanical allodynia and gene changes in mice.

The efficacy and safety of prophylactic antibiotics for post-acute stroke infection: A systematic review and meta-analysis.

Aims: Infections are common complications after stroke and associated with unfavourable outcomes. We aimed to evaluate the efficacy and safety of prophylactic antibiotics for post-acute stroke infection.

Methods: We searched PubMed, Embase, the Cochrane Library, SinoMed, China National Knowledge Infrastructure, WanFang Data, China Science and Technology Journal Database, and clinical trial register platforms from inception to 15 February 2022.

Mitigating end-to-end nonlinearity in LED-based VLC transceivers via optical intensity feedback: erratum.

We present an erratum to our Letter [Opt. Lett.47, 3688 (2022)10.

Mitigating end-to-end nonlinearity in LED-based VLC transceivers via an optical intensity feedback.

This Letter proposes a novel, to the best of our knowledge, intensity-modulation transmitter equipped with an optical intensity feedback (OIF) loop, which mitigates the holistic nonlinearity on both sides of intensity modulation and direct detection (IM/DD) transceivers from solely the transmitter side. In contrast to the recent effort on pre-distortion, we construct a negative feedback loop bridging the optical intensity of light-emitting diodes (LEDs) toward a sensor for nonlinearity perception to suppress the nonlinearity among all physical devices. In the meantime, we propose an analytical model for the feedback loop and an implementation scheme.

Modulation index dependence of intensity modulation bandwidth in visible light communications.

The modulation bandwidth of a light-emitting diode is inversely proportional to the carrier lifetime, which changes with varying injected current. However, in conventional implementations of visible light communications, the influence of bias current is always emphasized, while the effects of modulation indices and signal components are ignored. In this Letter, it is the first time, to the best of our knowledge, that the mechanism on how modulated signal components impact modulation bandwidth is clarified.

Optimized DFT-spread OFDM based visible light communications with multiple lighting sources.

Discrete Fourier transform spread orthogonal frequency-division multiplexing (DFT-S-OFDM) has demonstrated its capability in reducing peak to average ratio (PAPR), while maintaining reliable transmissions. This paper investigates the application of DFT-S-OFDM technology in visible light communications (VLC), and reveals the mechanism on how a multiple lighting distributed layout affects its performance. In addition, an optimization approach of lighting layout is proposed through making a trade-off between the strong interfered areas and the maximum delay spread inside.
