Increase in plasma succinate is associated with aerobic lactate production in a model of endotoxic shock

Experimental Physiology, Volume 110, Issue 4, Page 550-560, 1 April 2025.
Abstract The Krebs or tricarboxylic acid (TCA) cycle plays a key role in the regulation of immune responses and adaptations to hypoxia that occur during sepsis. Although the concentrations of some of these intermediates have been reported to be increased in large cohorts of septic patients, a detailed analysis of their changes during sepsis is still ...

The flavin reductase ActVB from Streptomyces coelicolor: characterization of the electron transferase activity of the flavoprotein form. [PDF]

, 2005
International audienceThe flavin reductase ActVB is involved in the last step of actinorhodin biosynthesis in Streptomyces coelicolor. Although ActVB can be isolated with some FMN bound, this form was not involved in the flavin reductase activity.

The impact of antibiotic therapy in psoriasis patients with active streptococcal infection: A prospective study

The Journal of Dermatology, Volume 52, Issue 3, Page 432-438, March 2025.
Abstract The association between psoriasis and streptococcal infection has been widely explored in both children and adults. However, the exact impact of Streptococcus pharyngeal infection on the course of psoriasis is not fully comprehended. This study explored the impact of Streptococcus pharyngeal infection on psoriasis and investigated the ...

Oxygen availability strongly affects chronological lifespan and thermotolerance in batch cultures of Saccharomyces cerevisiae

Microbial Cell, 2015
Stationary-phase (SP) batch cultures of Saccharomyces cerevisiae, in which growth has been arrested by carbon-source depletion, are widely applied to study chronological lifespan, quiescence and SP-associated robustness.

The role of habitat in predator–prey dynamics with applications to restoration

Restoration Ecology, Volume 33, Issue 3, March 2025.
Habitat is a powerful force in ecosystems, and the quantity and quality of habitat can shape ecosystem structure and function. Among the many important roles that habitat plays is as a mediator of ecological interactions, including predator–prey dynamics.

Dark Anaerobic Conditions Induce a Fast Induction of the Xanthophyll Cycle in Chlamydomonas reinhardtii When Exposed to High Light

Microorganisms
Background: Dark anaerobiosis promotes the acidification of the thylakoid lumen and a reduction in the plastoquinone (PQ) pool. The relationship between the reduction in the PQ pool in the dark and the induction of the xanthophyll cycle under high light ...

Time dynamics of the Bacillus cereus exoproteome are shaped by cellular oxidation

Frontiers in Microbiology, 2015
At low density, Bacillus cereus cells release a large variety of proteins into the extracellular medium when cultivated in pH-regulated, glucose-containing minimal medium, either in the presence or absence of oxygen. The majority of these exoproteins are

Bacterial Cellulose as a UVB Filter to Protect the Skin Microbiota

Macromolecular Bioscience, Volume 25, Issue 2, February 2025.
Bacterial cellulose (BC), a biomaterial produced by certain bacteria to protect themselves from UV represents an alternative to commercial UV filters. BC filters UVB radiation with high efficiency, especially at longer times, and protects the probiotics Lactobacillus fermentum and Cutibacterium acnes from UVB damage, which is relevant given the ...
