The GntR/VanR transcription regulator AlkR represses AlkB2 monooxygenase expression and regulates n‐alkane degradation in Pseudomonas aeruginosa SJTD‐1

open access: yesmLife, EarlyView.
Abstract Transmembrane alkane monooxygenase (AlkB)‐type monooxygenases, especially AlkB2 monooxygenases, are crucial for aerobic degradation of the medium‐to‐long‐chain n‐alkanes in hydrocarbon‐utilizing microorganisms. In this study, we identified a GntR/VanR transcription regulator AlkR of Pseudomonas aeruginosa SJTD‐1 involved in the negative ...

Monoclonal antibody OKM5 inhibits the in vitro binding of Plasmodium falciparum-infected erythrocytes to monocytes, endothelial, and C32 melanoma cells.

open access: yesJournal of Immunology, 1985
Plasmodium falciparum-infected erythrocytes bind in vitro to human endothelial cells, monocytes, and a certain melanoma cell line. Evidence suggests that this interaction is mediated by similar mechanisms which lead to the sequestration of parasitized ...

Plasticity of Gene Expression in Spaceflight and Postflight in Relation to Cardiovascular Disease: Mechanisms and Candidate Repurposed Drugs

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Spaceflight poses unique challenges to human health due to exposure to increased levels of cosmic radiation, microgravity, and associated oxidative stress. These environmental factors can lead to cellular damage, inflammation, and a range of health complications, including cardiovascular problems, immune system impairment, and an increased ...

Passivation Mechanism in Highly Luminescent Nanocomposite‐Based CH3NH3PbBr3 Perovskite Nanocrystals

open access: yesSmall Science, EarlyView.
A comprehensive investigation into the humidity‐driven crystallization dynamics of methylammonium lead bromide (MAPbBr3) NCs is presented, showing that increased RH promotes the transformation of 0D MA4PbBr6·2H2O into 3D MAPbBr3. The results emphasize the pivotal role of acetate basicity and in situ‐generated OH− in passivating NCs, enhancing their ...
