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

open access: yesFEBS 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.

ROSE Process Offers Energy Savings for Solvent Extraction

open access: yes, 1983
Kerr-McGee has developed and commercialized an energy-efficient solvent extraction process known as ROSE (Residuum Oil Supercritical Extraction) in which the extraction solvent is recovered as a supercritical fluid.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

EFFECT OF SOLVENT FLOW RATE ON THE SUPERCRITICAL CARBON DIOXIDE EXTRACTION OF ANDROGRAPHOLIDE FROM ANDROGRAPHIS PANICULATA [PDF]

open access: yes, 2006
Malaysia is one of the major medicinal plants (Andrographis paniculata) producers in the world. Extraction of bioactive component (andrographolide) from ground dried leaves of this plant using supercritical carbon dioxide has been studied.

The ubiquitin system in normal and infected germinal center B cells

open access: yesFEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS 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 ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

open access: yesMolecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Supramolecular chemistry in solvent extraction : toward highly selective extractants and a better understanding of phase-transfer phenomena

open access: yes, 2013
Solvent extraction provides the basis for important separation and concentration processes that are widely used in hydrometallurgy, waste treatment, ­ e ffluent purification, and material preparation 1– 3 . In a typical extraction process, the complexing

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

open access: yesMolecular 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 ...

Solvent extraction process for recovering bitumen from tar sand

open access: yes, 1987
patentBitumen recovered from tar sand by direct solvent extraction followed by washing of the sand tailings with countercurrent solvent flow and a solvent/aqueous phase separation step to recover solvent and residual ...
