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

Trace elements contents in Belarusian reservoirs and rivers bottom sediments according to monitoring

Журнал Белорусского государственного университета: География, геология, 2017
The trace elements (Ti, V, Cr, Mn, Ni, Cu, Zn, Mo, Pb) accumulation in modern bottom sediments of Belarusian reservoirs and rivers in the places of higher aquatic vegetation growing has been analyzed on monitoring data for the period of 2000 –2015 years.

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 ...

Differences in the properties of the bottom sediments in the system of Wdzydze Lakes (Northern Poland)

Soil and Water Research, 2008
The influence was determined of the anthropo-pressure on the changes in the properties of the bottom sediments, with particular consideration given to the properties of humic acids formed in the sediments. The system of the Wdzydze Lakes consists of four

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

Molecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Influence of denitrification in aquatic sediments on the nitrogen content of natural waters [PDF]

, 1976
A study was made of microbiological processes, particularly denitrification, leading to the elimination of nitrogen from natural waters. As denitrification is an anaerobic process and natural waters mostly contain dissolved oxygen, this process was ...

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Dynamic response of water flow and sediment transport off the Yellow River mouth to tides and waves in winter

Frontiers in Marine Science, 2023
Freshwater and sediments are transported from the Yellow River mouth downstream along the coast into Laizhou Bay under the northeasterly wind in winter. Numerical experiments indicate that sediment transport shows the tendency of convergence in the river

Unraveling the epigenetic code in cancer cell–tumor microenvironment crosstalk

Molecular Oncology, EarlyView.
Epigenetic regulation is a key driver of cancer development and progression. Diverse epigenetic alterations in cancer cells and components of the tumor microenvironment (TME) orchestrate their communication through multiple mechanisms. We discuss how the epigenetic code coordinates bidirectional cancer cell–TME crosstalk to promote cancer progression ...
