Mechanisms of Oxygen Taxis in Bacteria

Bioscience Reports, 1997
Since 1881 when Englemann reported aerotaxis in bacteria, an understanding of the molecular nature of the signal transduction remains a daring goal for microbiologists. This short review discusses known facts and recent advances in the field including the discovery of the flavoprotein receptor which drives Escherichia coli towards oxygen.

Rescue therapy with inhaled nitric oxide and almitrine in COVID-19 patients with severe acute respiratory distress syndrome

Annals of Intensive Care, 2020
Background In COVID-19 patients with severe acute respiratory distress syndrome (ARDS), the relatively preserved respiratory system compliance despite severe hypoxemia, with specific pulmonary vascular dysfunction, suggests a possible hemodynamic ...

Biomimetic nanomaterial-facilitated oxygen generation strategies for enhancing tumour treatment outcomes

Frontiers in Bioengineering and Biotechnology, 2022
Hypoxia, as a typical hallmark of the tumour microenvironment (TME), has been verified to exist in most malignancies and greatly hinders the outcome of tumour treatments, including chemotherapy, photodynamic therapy, radiotherapy, and immunotherapy ...

DataSheet_1_NADPH-Oxidase Derived Hydrogen Peroxide and Irs2b Facilitate Re-oxygenation-Induced Catch-Up Growth in Zebrafish Embryo.pdf

, 2022
Oxygen deprivation induces multiple changes at the cellular and organismal levels, and its re-supply also brings another special physiological status.

The chemistry of arachidonic acid oxygenation by prostaglandin endoperoxide synthase

Redox Biochemistry and Chemistry
Prostaglandins are an important class of bioactive lipids derived from arachidonic acid. The different classes of prostaglandins are produced from a common intermediate, called prostaglandin H2.

Critical oxygenation: Can muscle oxygenation inform us about critical power? [PDF]

, 2021
The power-duration relationship is well documented for athletic performance and is formulated out mathematically in the critical power (CP) model. The CP model, when applied properly, has great predictive power, e. g.

Prefrontal cortex oxygenation during endurance performance: A systematic review of functional near-infrared spectroscopy studies. [PDF]

, 2021
A myriad of factors underlie pacing-/exhaustion-decisions that are made during whole-body endurance performance. The prefrontal cortex (PFC) is a brain region that is crucial for decision-making, planning, and attention.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
