The activation of Chlamydomonas reinhardtii alpha amylase 2 by glutamine requires its N‐terminal aspartate kinase–chorismate mutase–tyrA (ACT) domain

Plant Direct, Volume 8, Issue 6, June 2024.
Abstract The coordination of assimilation pathways for all the elements that make up cellular components is a vital task for every organism. Integrating the assimilation and use of carbon (C) and nitrogen (N) is of particular importance because of the high cellular abundance of these elements.

The microbial cataclysm that forever changed life’s history

Earth History and Biodiversity
After a full century of search, evidence of Darwin’s “missing” pre-Cambrian fossil record was finally discovered in the mid-1950s. Unsurprisingly, given the then widely held belief that Precambrian life was not only unknown but unknowable, the initial ...

Postbiotics of Lacticaseibacillus paracasei CECT 9610 and Lactiplantibacillus plantarum CECT 9608 attenuates store‐operated calcium entry and FAK phosphorylation in colorectal cancer cells

Molecular Oncology, Volume 18, Issue 5, Page 1123-1142, May 2024.
Colorectal cancer (CRC) cells exhibit altered store‐operated Ca2+ entry (SOCE), showing enhanced Ca2+ entry and expression of Orai1 and STIM1 proteins, which also increases cell migration. Exposure of CRC cells to Lacticaseibacillus paracasei and Lactiplantibacillus plantarum postbiotics reduces the expression of these proteins, resulting in a decrease

Susceptibility of strict and facultative anaerobes Isolated from endodontic infections to metronidazole and beta-lactams

Journal of Applied Oral Science, 2007
Endodontic infections are mixed aerobic-anaerobic infections and several microbial groups associated to these pathologies are also involved in orofacial infections. The goal of this study was to evaluate the susceptibility of microorganisms isolated from

Comparable bacterial growth in platelet concentrates suspended in plasma and platelet additive solution and improved detection of bacterial contamination using a new generation automated culture system

Transfusion, Volume 64, Issue 4, Page 665-673, April 2024.
Abstract Background Microbial screening of platelet concentrates (PC) with automated culture methods is widely implemented to reduce septic transfusion reactions. Herein, detection of bacterial contamination in PC was compared between units prepared in plasma and a mix of plasma and platelet additive solution (PAS) and between the BACT/ALERT 3D and ...

Detection of zoonotic enteropathogens in captive large felids in Italy

Zoonoses and Public Health, Volume 71, Issue 2, Page 200-209, March 2024.
Abstract Aims Within the One Health paradigm, infectious disease surveillance have been developed for domestic and wild animals, leaving the role of captive non‐domestic populations, especially felids in zoos and circuses, less explored. This study addresses the proximity of these captive animals to urban areas, necessitating focused monitoring for ...

Role of perfusion medium in rewarming machine perfusion from hypo‐ to normothermia

Artificial Organs, Volume 48, Issue 2, Page 150-156, February 2024.
The study compares intra‐ and extracellular type perfusion media for the use in machine perfusion‐assisted rewarming from hypo‐ to normothermia. The results show that Belzer MPS seems to be an alternative to a normothermic medium like Steen solution for rewarming machine perfusion.

Numbers of Cyd, Cyo, ArcA and FNR molecules per E. coli cell at different points on the aerobiosis scale.

, 2014
The Cyd, Cyo and ArcA numbers are those reported by Rolfe et al. [3]. The number of FNR molecules per cell was calculated by from analysis of Western blots developed with anti-FNR serum for whole cell samples taken from steady-state cultures at the ...

Investigating the Potential of L(+)-Lactic Acid as a Green Inhibitor and Eradicator of a Dual-Species Campylobacter spp. Biofilm Formed on Food Processing Model Surfaces

Microorganisms
Campylobacter spp. are prevalent foodborne bacterial enteric pathogens. Their inclusion in biofilms on abiotic surfaces is considered a strategy that facilitates their extraintestinal survival.
