Surface Sulfurization of Cubic CuO to Form CuS Nanostructure-Decorated Catalysts for Light-Enhanced Electrocatalytic H Evolution and Photocatalytic CO Reduction.

Developing highly efficient bifunctional catalysts for electrocatalysis and photocatalysis suffers from sluggish charge transfer and poor photo-to-electric conversion rate. Herein, micro-sized CuO cubes were initially prepared for subsequent transformation into CuO@CuS core-shell structures by a slight surface sulfurization. The formation of nanostructured CuS thin layer at CuO surface can endow an immediate charge separation and migration under light irradiation, leading to high surface photovoltages (SPV, 18-30 mV).

Transcription factor networks drive perforin activity in the anti-bacterial immune response of tilapia.

Perforin, produced by natural killer (NK) cells and cytotoxic T lymphocytes (CTLs), is one of the effectors of cell-mediated cytotoxicity (CMC) in vertebrates, playing a paramount role in killing target cells. However, whether and how perforin is involved in adaptive immune responses in early vertebrates remains unclear. Using Nile tilapia (Oreochromis niloticus) as a model, we investigated the characteristics of perforin in early vertebrates.

Posphoproteomics profiling reveals the regulatory role of a phosphorylated protein PvFBA1 in cadmium tolerance in seashore paspalum.

A digital workflow for fabricating a mandibular guide plane prosthesis for patients about to undergo hemimandibulectomy: A dental technique.

Patients who undergo hemimandibulectomy have multiple functional impairments, and early initiation of guidance therapy has been associated with an improved definitive occlusal relationship. This article describes a digital workflow to determine the angle and form the shape of the flange of the mandibular guide plane prosthesis (MGPP), and to create an MGPP before mandibular resection surgery. A virtual articulator was used to achieve the movements of the maxilla relative to the mandible, and the shape of the MGPP was adjusted by dynamic occlusion.

Granzyme B secreted by T cells is involved in anti-bacterial immune response of tilapia.

Secreted by natural killer cells and cytotoxic T lymphocytes, Granzyme B is involved in regulating the adaptive immune response in vertebrates and plays a pivotal role in resisting virus invasion and removing pathogens. Although it had been extensively studied in mammals, the involvement of Granzyme B in adaptive immune response of early vertebrates remained elusive. In this study, we investigated the Granzyme B in Oreochromis niloticus (OnGrB), found that its function domain was conserved.

The TAK1/JNK axis participates in adaptive immunity by promoting lymphocyte activation in Nile tilapia.

The transforming growth factor beta-activated kinase 1 (TAK1)/c-Jun N-terminal kinase (JNK) axis is an essential MAPK upstream mediator and regulates immune signaling pathways. However, whether the TAK1/JNK axis harnesses the strength in regulation of signal transduction in early vertebrate adaptive immunity is unclear. In this study, by modeling on Nile tilapia (Oreochromis niloticus), we investigated the potential regulatory function of TAK1/JNK axis on lymphocyte-mediated adaptive immune response.

Naringenin regulates cigarette smoke extract-induced extracellular vesicles from alveolar macrophage to attenuate the mouse lung epithelial ferroptosis through activating EV miR-23a-3p/ACSL4 axis.

Background: Alveolar macrophages are one of the momentous regulators in pulmonary inflammatory responses, which can secrete extracellular vesicles (EVs) packing miRNAs. Ferroptosis, an iron-dependent cell death, is associated with cigarette smoke-induced lung injury, and EVs have been reported to regulate ferroptosis by transporting intracellular iron. However, the regulatory mechanism of alveolar macrophage-derived EVs has not been clearly illuminated in smoking-related pulmonary ferroptosis.

Preparation and Synergistic Effect of Biomimetic Poly(lactic acid)/Graphene Oxide Composite Scaffolds Loaded with Dual Drugs.

To promote the bone repair ability of drug-loaded scaffolds, poly(lactic acid) (PLA)/graphene oxide (GO)/Salvianolic acid B (Sal-B)/aspirin (ASA) dual drug-loaded biomimetic composite scaffolds were prepared. The results showed that the addition of these two drugs delayed the gel formation of the composite system, but a biomimetic nanofiber structure could still be obtained by extending the gel time. The addition of Sal-B increased the hydrophilicity of the scaffold, while an increase in ASA reduced the porosity.
