Structure-function correlations and system dynamics in oxygenic photosynthesis: classical perspectives and murburn precepts.

Journal of biomolecular structure & dynamics

J Biomol Struct Dyn. 2021 Jul 29;1-27. doi: 10.1080/07391102.2021.1953606. Epub 2021 Jul 29.

HIGHLIGHTS: Contemporary beliefs on oxygenic photosynthesis are critiqued.Murburn model is suggested as an alternative explanation.In the new model, diffusible reactive species are the main protagonists.All pigments are deemed photo-redox active in the new stochastic mechanism.NADPH synthesis occurs via simple...

Complexation of ferrous ions by ferrozine, 2,2'-bipyridine and 1,10-phenanthroline: Implication for the quantification of iron in biological systems.

Journal of inorganic biochemistry

Smith GL, Reutovich AA, Srivastava AK, Reichard RE, Welsh CH, Melman A, Bou-Abdallah F.
PMID: 33866045
J Inorg Biochem. 2021 Jul;220:111460. doi: 10.1016/j.jinorgbio.2021.111460. Epub 2021 Apr 15.

Iron is an essential nutrient for virtually all forms of life. Because of its redox properties and involvement in a wide range of biological processes, a number of qualitative and quantitative chemical tools have been developed to detect reduced...

Recent advances in clinical practice: epidemiology of autoimmune liver diseases.

Gut

Trivedi PJ, Hirschfield GM.
PMID: 34266966
Gut. 2021 Oct;70(10):1989-2003. doi: 10.1136/gutjnl-2020-322362. Epub 2021 Jul 15.

Autoimmune liver diseases are chronic inflammatory hepatobiliary disorders that when classically defined encompass three distinctive clinical presentations; primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH). Meaningful changes in disease epidemiology are reported, with increasing incidence...

Murburn precepts for lactic-acidosis, Cori cycle, and Warburg effect: Interactive dynamics of dehydrogenases, protons, and oxygen.

Journal of cellular physiology

Manoj KM, Nirusimhan V, Parashar A, Edward J, Gideon DA.
PMID: 34927737
J Cell Physiol. 2021 Dec 20; doi: 10.1002/jcp.30661. Epub 2021 Dec 20.

It is unresolved why lactate is transported to the liver for further utilization within the physiological purview of Cori cycle, when muscles have more lactate dehydrogenase (LDH) than liver. We point out that the answer lies in thermodynamics/equilibriums. While...

Operon dynamics with state dependent transcription and/or translation delays.

Journal of mathematical biology

Gedeon T, Humphries AR, Mackey MC, Walther HO, Wang Z.
PMID: 34905089
J Math Biol. 2021 Dec 14;84(1):2. doi: 10.1007/s00285-021-01693-0.

Transcription and translation retrieve and operationalize gene encoded information in cells. These processes are not instantaneous and incur significant delays. In this paper we study Goodwin models of both inducible and repressible operons with state-dependent delays. The paper provides...
