Acetogenic bacteria play an important role in various biotechnological processes, because of their chemolithoautotrophic metabolism converting carbon dioxide with molecular hydrogen (H) as electron donor into acetate. As the main factor limiting acetogenesis is often H, insights into the H consumption kinetics of acetogens are required to assess their potential in biotechnological processes. In this study, initial H consumption rates at a range of different initial H concentrations were measured for three different acetogens.

Consequent hyperoxia has been associated with unfavourable outcomes including in patients with brain injury, after cardiac arrest, sepsis, and traumatic brain injury. The aim of this systematic review was to explore the association between hyperoxia exposure and unfavourable outcome in patients following a non-traumatic subarachnoid haemorrhage (SAH).

- Systematic reviews (SRs) and meta-analyses (MAs) published in top neurosurgical journals were evaluated for their methods of assessing research quality between 2019 and 2021.
- A total of 564 SRs were analyzed, finding that while scales were commonly used for quality assessments, there was significant room for improvement, especially in studies with non-randomized designs.
- The study concludes that using domain-based tools for assessing methodological quality may provide a more thorough evaluation compared to other methods.
Article Synopsis
- Understanding the relationship between the structure and properties of electrocatalysts is essential for designing better materials, and the Aarhus University reactor for electrochemical studies using X-rays (AUREX) provides a versatile and user-friendly setup for this research.
- The AUREX cell allows for various advanced measurement techniques like total scattering, diffraction, and absorption spectroscopy on commercial silver electrocatalysts, enabling real-time observation of structural changes during electrochemical reactions.
- The findings reveal that silver transitions from a face-centered cubic structure to other phases under oxidative conditions, and the setup is crucial for studying these phase transitions, highlighting the need for careful beam settings to avoid interference during experiments.
Resonance Raman spectroscopy has been performed on a set of cytochrome P450 BM3 heme domains in which mutation of the highly conserved Phe393 induces significant variation in heme iron reduction potential. In previous work [Chen, Z., Ost, T.
