Lysosome-related proteins may have changes in the urinary exosomes of patients with acute gout attack.

Background: The autophagy-lysosome is intricately linked to the development of gout. At present, the diagnosis and monitoring of gout are mainly invasive tests, which cannot predict the occurrence of gout in the acute phase, and bring new pain to patients. This study focuses on the changes of lysosome-related proteins in urinary exosomes of patients with acute gout attack to explore the potential noninvasive biomarkers clinical application value.

Structural mechanism underlying PHO1;H1-mediated phosphate transport in Arabidopsis.

Arabidopsis PHOSPHATE 1 (AtPHO1) and its closest homologue AtPHO1;H1 are phosphate transporters that load phosphate into the xylem vessel for root-to-shoot translocation. AtPHO1 and AtPHO1;H1 are prototypical members of the unique SPX-EXS family, whose structural and molecular mechanisms remain elusive. In this study, we determined the cryogenic electron microscopy structure of AtPHO1;H1 binding with inorganic phosphate (Pi) and inositol hexakisphosphate in a closed conformation.

Evaluation of land ecological security and driving factors in the Lower Yellow River Flood Plain based on quality, structure and function.

Land ecological security (LES) is crucial for human well-being and sustainable development, especially in areas like the Lower Yellow River Flood Plain (LYRFP), which faces flood threats, economic challenges, and ecological fragility. This study introduces a "Quality-Structure-Function" framework for evaluating LYRFP's LES, incorporating ecological baselines and the impacts of land use changes on human well-being for a comprehensive assessment. Using the Optimal Parameter Geographic Detector (OPGD) model, we analyzed agricultural, industrial, and socio-economic factors as potential LES drivers.

Identification of glutamine as a potential therapeutic target in dry eye disease.

Dry eye disease (DED) is a prevalent inflammatory condition significantly impacting quality of life, yet lacks effective pharmacological therapies. Herein, we proposed a novel approach to modulate the inflammation through metabolic remodeling, thus promoting dry eye recovery. Our study demonstrated that co-treatment with mesenchymal stem cells (MSCs) and thymosin beta-4 (Tβ4) yielded the best therapeutic outcome against dry eye, surpassing monotherapy outcomes.

Effects of linkers on the development of liposomal docetaxel-glutathione prepared by active click loading.

Loading drug-maleimide (MAL) conjugates into liposomes preloaded with glutathione (GSH) can prepare the liposome encapsulating GSH-conjugated prodrugs, which serve as a feasible way to construct liposomal formulation. However, the effects ofthelinker on the development of this liposomal system remained unclear. Herein, docetaxel (DTX)-MAL conjugates linked by various linkers were used for such studies.
