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

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.

Variations in the branching pattern of the popliteal artery in the north Karnataka region: A cadaveric study

Indian Journal of Health Sciences and Biomedical Research KLEU
INTRODUCTION: The clinically most important artery of the lower extremities is the popliteal artery. The normal branching pattern of the popliteal artery ranges between 92% and 96%.

Astrocytes exhibit diverse Ca2+ changes at subcellular domains during brain aging

Frontiers in Aging Neuroscience, 2022
Astrocytic Ca2+ transients are essential for astrocyte integration into neural circuits. These Ca2+ transients are primarily sequestered in subcellular domains, including primary branches, branchlets and leaflets, and endfeet.

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

FEBS 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.

Numerical simulation of gas–liquid two-phase flow in a horizontal manifold with downward branches

Journal of Fluid Science and Technology
Large eddy simulations (LESs) with the volume of fluid (VOF) method are applied to gas–liquid two-phase flows in a horizontal manifold with five downward branches under various inlet flow rates and quality conditions, and the validity is examined by ...

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 ...

Energy Consumption during Cutting Tree Branches of Fig (Ficus carica) [PDF]

Journal of Soil Sciences and Agricultural Engineering, 2019
This study evaluated energy consumption for cutting tree branches of the fig in different moisture contents (MC) levels at 10, 16, 20 and 25 % w.b., branch diameter levels at 0.5, 1, 1.5 and 2 cm, two types of cutting knives, smooth & serrated and ...

Partons and branching

Physics Letters B, 1979
Abstract We formulate an evolution equation for the generating functional of parton distributions. It permits a detailed study of the branching process. Several numerical examples are given, and the relevance for jet phenomenology discussed.

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.
