Identification of the matrix metalloproteinase (MMP) gene family of Trachinotus ovatus and expression analysis in response to Streptococcus agalactiae and Cryptocaryon irritans.

Matrix metalloproteinases (MMPs) represent a group of zinc-dependent endopeptidases that degrade various protein components of the extracellular matrix (ECM). These enzymes play a role in multiple biological and pathological processes, including tissue remodeling, growth, trauma repair, defense mechanisms, and immune response. However, their role in immune response in Trachinotus ovatus is still unclear.

Revealing a Nonlinear Photocurrent in the Graphene/MoS Heterostructure via Terahertz Emission Spectroscopy.

Heterostructures composed of graphene (Gr) and transition metal dichalcogenides (TMDs) establish a new platform for optoelectronic applications.

Therefore, this study applied a novel technique (low voltage electrostatic field, LVEF) combined with ice-temperature (0 °C) treatment on litchi and evaluated its quality characteristics during storage.

Phosphorylation of S-S-S Motif in Nuclear Export Protein (NEP) Plays a Critical Role in Viral Ribonucleoprotein (vRNP) Nuclear Export of Influenza A and B Viruses.

SAMCT: Segment Any CT Allowing Labor-Free Task-Indicator Prompts.

Segment anything model (SAM), a foundation model with superior versatility and generalization across diverse segmentation tasks, has attracted widespread attention in medical imaging. However, it has been proved that SAM would encounter severe performance degradation due to the lack of medical knowledge in training and local feature encoding. Though several SAM-based models have been proposed for tuning SAM in medical imaging, they still suffer from insufficient feature extraction and highly rely on high-quality prompts.

Structural Comparisons, Fluorescence Properties, and Glass-to-Crystal Transformations of Heat-Cooled and Melt-Quenched Zeolitic Imidazolate Framework Glass.

As a representative of zeolitic imidazolate framework glass, agZIF-62 has been reported to be synthesized using a melt-quenching method in which the ZIF-62 crystal is heated to a temperature above the melting point. Interestingly, we unexpectedly found that agZIF-62 can also be synthesized by simple heating at temperatures lower than the melting point, which may be assisted by the release of encapsulated solvent molecules. The structural differences between melt-quenched agZIF-62 (MQ-agZIF-62) and heat-cooled agZIF-62 (HC-agZIF-62) were investigated.

Inhibition of RAN attenuates influenza a virus replication and nucleoprotein nuclear export.

Nuclear export of the viral ribonucleoprotein (vRNP) is a critical step in the influenza A virus (IAV) life cycle and may be an effective target for the development of anti-IAV drugs.
