The Barrier Properties of Biological Membranes Dictate How Cells Experience Oxidative Stress
Molecular Microbiology, Volume 123, Issue 5, Page 454-463, May 2025.Molecular oxygen diffuses across membranes with such speed that, despite respiration, the intracellular oxygen concentration does not differ significantly from that outside the cell. In contrast, membranes are important barriers for hydrogen peroxide and especially superoxide, so that intracellular scavenging enzymes can substantially shield cells from

Quelques observations sur les conditions de la formation d'anhydride sulfureux en vinification
OENO One, 1985 Les formations importantes de SO2 en vinification en blanc dans les conditions de la pratique pourraient s'expliquer soit par l'intervention de levures particulières soit par des fermentations particulièrement lentes, à basses températures, dans des ...

The incorporation of labeled lysine into the proteins of guinea pig liver homogenate [PDF]
, 1949 When C14-labeled lysine is incubated with guinea pig liver homogenate, α-aminoadipic, α-ketoadipic, and glutaric acids are formed from the lysine (1). These transformations were established by finding the radioactivity of the C14 tracer in the metabolic ...

Microbial Biotechnology, Volume 18, Issue 4, April 2025.We compare the differences in nitrogen metabolism of S. cerevisiae, S. uvarum and S. kudriavzevii using isotopic tracing and modelling. We observed differences in ammonium, arginine and glutamine uptake, in the contribution of leucine and valine on aroma synthesis and S. kudriavzevii activates the aroma synthesis earlier.

Chemical Characterisation and Biorefinery Efficiency of Timothy Grass and Pulp Silages
Grass and Forage Science, Volume 80, Issue 2, June 2025.ABSTRACT This study investigated the effects of increased dry matter concentration by screw‐pressing or wilting and additive application on fermentation quality of primary growth (PG) and first regrowth (ReG) timothy grass. Additionally, the nutritional quality of the liquid produced during the screw‐pressing of pre‐ensiled and ensiled biomasses was ...

High altitude adaptation and anaerobiosis in sceloporine lizards [PDF]
Comparative Biochemistry and Physiology Part A: Physiology, 1975 Abstract o 1. The duration of maximal activity and the intensity of anaerobic metabolism were measured in lowland Sceloporus occidentalis at low (200 ft) and high (10,150 ft) elevations and compared to those of resident S. occidentalis and S. graciosus at high altitude. 2.

Journal of Periodontal Research, Volume 60, Issue 4, Page 361-372, April 2025.Experimental periodontitis model was induced with oral gavages with Porphyromonas gingivalis and Fusobacterium nucleatum over 4 (P + 4 w), 8 (P + 8 w) and 12 (P + 12 w) weeks. Bone levels were measured with micro‐CT (linear and volumetric variables) and microscope (linear morphometric measurements) at the mandible first molar. Clinical variables—plaque
