Harvesting low-velocity water flow energy stably over the long term is a significant challenge. Herein, a flexible rolling triboelectric nanogenerator with a bionic gill cover structure (GFR-TENG) to harvest steady low-velocity water flow energy is proposed. The dielectric material of the GFR-TENG is eight flexible hollow fluorinated ethylene propylene (FEP) pipes, which guarantees that rolling friction is formed between the dielectric material and copper electrode.

Analysis of virtual water risk transmission characteristics and driving factors from the perspective of WEF trade is highly important for alleviating the risk of water shortages and promoting the efficient use of resources. In this paper, a set of methods for quantifying risk transmission values is constructed on the basis of China's interregional input-output model, and the key paths of interregional virtual water risk transmission caused by WEF trade are identified using innovative methods.

Compared with only pH shifting or ultrasound treatment, the solubility of YPs with the combined treatment of ultrasonic and pH shifting was increased significantly. The soluble protein content of pH-U400 reached 85.

Although transferrin receptor (TfR)-mediated transcytosis is widely employed for brain drug delivery, the inefficient release of therapeutic payload hinders their efficacy from crossing the BBB. Here, we developed a pH-responsive anti-polyethylene glycol (PEG) × anti-TfR bispecific antibody (pH-PEG engager) that can complex with PEGylated nanomedicine at physiological pH to trigger TfR-mediated transcytosis in the brain microvascular endothelial cells, while rapidly dissociating from PEGylated nanomedicine at acidic endosomes for efficient release of PEGylated nanomedicine to cross the BBB.

We searched Embase, PubMed, Web of Science, and Cochrane Library to identify studies about cancer patients with immunotherapy until November 29, 2024. Retrospective or prospective cohort studies with pretreatment NLR data were included.
