Control of the geomorphology and gas hydrate extent on widespread gas emissions offshore Romania

BSGF - Earth Sciences Bulletin, 2017
The Romanian sector of the Black Sea deserves attention because the Danube deep-sea fan is one of the largest sediment depositional systems worldwide and is considered the world's most isolated sea, the largest anoxic water body on the planet and a ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Pore structure and free gas transport characteristics of deep shale: taking Longmaxi Formation shale in Sichuan Basin as an example

Shiyou shiyan dizhi, 2023
Deep shale gas is an important research direction for increasing shale gas storage and production in the Longmaxi Formation of Sichuan Basin. But there are differences in reservoir and seepage characteristics between shallow and medium-buried shale gas ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Multi-phase coalbed methane content model in deep strata of eastern margin of Ordos Basin

Meitan kexue jishu
The deep coalbed methane resources in the Ordos Basin are abundant. Accurately understanding the laws and underlying mechanisms of coalbed methane content phase change is of great significance for achieving large-scale and efficient development of deep ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Discussion on formation mechanism of pores and reservoir-forming characteristics of deep coal seams in Ordos Basin

Youqi dizhi yu caishoulu
The deep part of the Ordos Basin is rich in coalbed methane resources. Understanding the characteristics of deep coalbed methane accumulation is of great geological significance for the geological evaluation and selection of deep coalbed methane ...

Non-resistivity-based saturation evaluation methods in shale gas reservoirs

Energy Geoscience, 2023
Free gas saturation is a key parameter for calculating shale gas reserves. The complex conductivity mechanism of shale reservoirs restricts the application of Archie's formula and its extended form for the evaluation of free gas saturation.
