Hyperspectral Imaging Techniques in Search of Geologic Hydrogen: A Review

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
New energy sources are crucial for powering next-generation transportation and supplying reliable energy in remote regions. Hydrogen is an attractive energy carrier because its utilization produces only water as a byproduct.

Research progress on pipeline transportation technology of hydrogen-mixed natural gas

You-qi chuyun, 2021
Hydrogen energy is recognized as a clean energy, and mixing hydrogen into natural gas pipeline is an effective way to transport hydrogen on a large scale. However, as the physical properties of hydrogen vary greatly from those of natural gas, the quality

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids

FEBS Open Bio, EarlyView.
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy

FEBS Open Bio, EarlyView.
This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...
