Carbon monoxide (CO) is a significant gasotransmitter that naturally modulates inflammatory responses. Visualization of CO in situ would help to reveal its physiological/pathological functions. Unfortunately, most existing fluorescent probes show aggregation-caused quenching (ACQ) properties. Herein, we report the reaction-based probe (BTCV-CO) with aggregation-induced emission (AIE) characteristics for detection and imaging. This ratiometric AIE showed excellent stability, high sensitivity...

MicroRNAs (miRNAs) are a class of small, single-stranded, noncoding, functional RNAs. Hepatitis B virus (HBV) is an enveloped DNA with virions and subviral forms particles that lack core. It was not known whether HBV encodes miRNAs. Here, we identified HBV-encoded miRNA (called HBV-miR-3) by deep sequencing Northern blotting. HBV-miR-3 located at nucleotides (nt) 373 to 393 the genome generated from 3.5-kb, 2.4-kb, 2.1-kb in classic biogenesis (Drosha-Dicer-dependent) manner. highly...

An efficient, general, and one-pot procedure for the synthesis of multisubstituted xanthene derivatives through Fe(III)-catalyzed reactions 2-aryloxybenzaldehydes with electron-rich arenes has been developed. This method offers several advantages such as high selectivities, mild reaction conditions, easily accessible starting materials. A mechanistic study revealed that a C−C bond cleavage triarylmethane intermediate might be involved in domino process.

Background Inhibition of the epidermal growth factor receptor (EGFR) has shown clinical success in patients with advanced non-small cell lung cancer (NSCLC). Somatic mutations EGFR were found adenocarcinoma that lead to exquisite dependency on signaling; thus EGFR-mutant tumors are at high chance response inhibitors. However, imaging approaches affording early identification tumor EGFR-dependent carcinomas have so far been lacking. Methodology/Principal Findings We performed a systematic...

Metal-organic framework (MOF)-based derivatives have attracted an increasing interest in various research fields. However, most of the reported papers mainly focus on pristine MOF-based derivatives, and studies functional derivative composites are rare. Here, a simple strategy has been to design by encapsulation metal nanoparticle (MNP) MOF matrixes (MNP@MOF) high-temperature calcination MNP@MOF composites. The as-prepared MNP@metal oxide with hierarchical pore structure exhibited excellent...
