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.

The shapeshifting Helicobacter pylori: From a corkscrew to a ball

Molecular Microbiology, Volume 121, Issue 2, Page 260-274, February 2024.
Helicobacter pylori transforms from helical rods to spherical coccoids when faced with various stresses, including starvation and temperature fluctuations. While it remains controversial whether the latter form is dormant or degenerative, a great deal of overlooked evidence points toward the existence of both.

Ribonucleotide reductases of Salmonella Typhimurium : transcriptional regulation and differential role in pathogenesis [PDF]

, 2010
Ribonucleotide reductases (RNRs) are essential enzymes that carry out the de novo synthesis of deoxyribonucleotides by reducing ribonucleotides. There are three different classes of RNRs (I, II and III), all having different oxygen dependency and ...
