Understanding the Catalytic Determinant role of Diaphorase‐Like Subunit in Formate Dehydrogenases via Redox Couples

Advanced Science, EarlyView.
A unique mechanism of catalytic bias regulated by diaphorase‐like subunit in formate dehydrogenase from Rhodobacter aestuarii is revealed. The diaphorase‐like subunit functions act as a biological “voltage rheostat” that controls the slow release of NADH to regulate redox balance, biasing the enzyme's catalytic preference toward CO2 reduction over ...

Myeloid p38 activation maintains macrophage–liver crosstalk and BAT thermogenesis through IL‐12–FGF21 axis

Hepatology, EarlyView., 2022
Physiological activation of myeloid p38 controls macrophage IL‐12 production and crosstalk to the liver by modulating hepatic FGF21, and subsequently, brown adipose tissue thermogenesis during obesity Abstract Obesity features excessive fat accumulation in several body tissues and induces a state of chronic low‐grade inflammation that contributes to ...

SIRT6‐Mediated Deacetylation of ATF3 Promotes Silica‐Induced Lung Fibrosis by Enhancing its Nuclear Import via Binding to Importin α

Advanced Science, EarlyView.
SIRT6‐mediated ATF3 acetylation drives MGARP transcription and mitochondrial dysfunction in macrophages, promoting macrophage senescence and pulmonary fibrosis. Mechanistically, HSP70/Importin α competitively binds to ATF3, modulating its nuclear translocation.

Interpretation of transient caving dust patterns during sequential caving operation in LTCC face [PDF]

Podzemni Radovi
Longwall top coal caving (LTCC) is a mining technology introduced for enhancing the coal production rate by using the top coal caving (TCC) operations for thick seams. LTCC mine increases coal production rates but at the expense of high dust exposure and

Respirable dust index for Indian coals

, 1984
Respirable dust index (RDI) has been taken as a property of coal with respect to its proneness to produce respirable dust and it is a measure of total yield of respirable dust as a percentage of original coal.

Xenogeneic Mitochondrial Transplantation Improves Selected Age‐Associated Phenotypes in Mice

Advanced Science, EarlyView.
Yak‐derived xenogeneic mitochondrial transplantation improves selected age‐associated phenotypes in mice, enhances mitochondrial functional readouts, and engages host mitochondrial quality‐control pathways. Broad tissue biodistribution, increased ATP production and mtDNA copy number, reduced ROS levels and dysfunctional mitochondria, improved motility ...

Migration patterns of respirable dust and precision dust control and removal technology in coal mine belt conveyor roadways

Gong-kuang zidonghua
The belt conveyor roadway is the main operation site for coal transportation. During long-distance conveying, a large amount of respirable dust is generated, increasing both the risk of pneumoconiosis and the potential for coal dust explosions.

Filtration Performance of Dust Respirators Against Nanoparticles

Journal of UOEH, 2011
It is necessary to consider protective measures, such as dust respirators, against the inhalation of nanoparticle aerosols. Industrial hygienists and workers handling nanomaterials are concerned about the filteration performance of dust respirators in protecting against nanoparticles, the size of which is less than 100 nm.

Mitochondrial Carrier SLC25A13 Drives Ferroptosis Resistance and Immune Evasion via a STAT3–IFI6 Circuit in Breast Cancer

Advanced Science, EarlyView.
SLC25A13 is identified as an immunometabolic driver of triple‐negative breast cancer that sustains ferroptosis resistance and immune evasion through a STAT3–IFI6 circuit. Pharmacologic degradation of SLC25A13 restores ferroptosis sensitivity and enhances anti‐PD‐1 efficacy, highlighting a strategy to convert immune‐cold tumors into immunotherapy ...
