Lanthanide-Assisted Function Tailoring of the HOF-Based Logic Gate Sensor Array for Biothiol Detection and Disease Discrimination.

The advancement of lanthanide fingerprint sensors characterized by targeted emission responses and low self-fluorescence interference for the detection of biothiols is of considerable importance for the early diagnosis and treatment of cancer. Herein, the lanthanide "personality function tailoring" HOF composite sensor array is designed for the specific discrimination of biothiols (GSH, Cys, and Hcy) based on the activation of various luminescent molecules, such as r-AuNCs/luminol via HOF surface proximity. Lumi-HOF@Ce serves as a versatile platform for catalyzing the oxidation of -phenylenediamine (OPD) to generate yellow fluorescent oligomers, accompanied by the fluorescence attenuation of luminol.

Insights into the catalytic mechanism of archaeal peptidoglycan endoisopeptidases from methanogenic phages.

Archaeal peptidoglycan, a crucial component of the cell walls of Methanobacteria and Methanopyri, enhances the tightness of methanogenic cells and their resistance to known lytic enzymes and antibiotics. Although archaeal peptidoglycan endoisopeptidases (Pei) can reportedly degrade archaeal peptidoglycan, their biochemistry is still largely unknown. In this study, we investigated the activity and catalytic properties of the endoisopeptidases PeiW and PeiP using synthesized isopeptides identical to natural substrates.

LAPTM5 Confers the Resistance to Venetoclax via Promoting the Autophagosome-Lysosome Fusion in Multiple Myeloma.

Multiple myeloma (MM) is a haematological lymphoid malignancy marked by significant morbidity due to severe complications. Despite advances in targeted therapies, including proteasome inhibitors and the BCL-2 inhibitor venetoclax, drug resistance frequently occurs, with the underlying mechanisms poorly understood. This study investigates the role of lysosome-associated protein transmembrane 5 (LAPTM5) in conferring resistance to venetoclax in relapsed MM.

A small molecule modified UiO series MOFs for simultaneous detection of Fe and Zn.

Iron and zinc are two metal ions with important roles in biology, industry and the environment, however, the excess or deficiency of both Fe and Zn can have negative effects on organisms and environment. Therefore, the development of efficient method for simultaneous detection of Fe and Zn provides timely information on metal content, simplifies operations and improves efficiency. In this work, a small molecule (COOH-BPEA) of recognizing Zn modified the four metal-organic-framework (MOF) (UiO-66-X(66, OH, NH and OH/NH)) was developed for the simultaneous detection of Fe and Zn.

Volatile profiles and characteristic odorants in camellia seeds with different heat pretreatments.

Heat pretreatment plays a crucial role in affecting the quality, colour and aroma of camellia oil during the extraction process. This study aimed to investigate the effects of steaming, stir-frying, roasting, microwave and infrared treatment on the flavour and physicochemical quality of camellia seeds. The results indicated that, compared with unpretreated samples, the heat-pretreated ones exhibited increased oil content and browning degree, imparting a caramel colour with toasty and nutty flavours.
