Selective advantage of aerobic glycolysis over oxidative phosphorylation [PDF]

arXiv
The utilization of glycolysis in aerobic conditions have been a subject of debate for more than a century. A hypothesis supported by previous data is that glycolysis has a higher rate of ATP production per protein mass and per occupied volume than oxidative phosphorylation (OxPhos).

A phenomenological approach to the simulation of metabolism and proliferation dynamics of large tumour cell populations

, 2005
A major goal of modern computational biology is to simulate the collective behaviour of large cell populations starting from the intricate web of molecular interactions occurring at the microscopic level.

The Effect of Environmental Factors on the Nitrate and Nitrite Metabolism of Oral Actinomyces and Schaalia Species. [PDF]

Mol Oral Microbiol
ABSTRACT Actinomyces naeslundii and Schaalia odontolytica belong to the most predominant nitrite‐producing bacteria in the oral microbiome. Nitrite has antibacterial and vasodilatory effects that may contribute to maintaining oral and systemic health. We have previously elucidated the metabolic characteristics of the nitrite‐producing activity of oral ...

Gut Microbiota Regulate Lipid Metabolism via the Bile Acid Pathway: Resistance to Hypoxia in Gansu Zokor (Eospalax cansus)

Integrative Zoology, EarlyView.
The gut microbiota regulates lipid metabolism of Gansu zokor (Eospalax cansus) through the bile acid pathway in hypoxic environments, reflecting the unique survival strategy of subterranean rodents to maintain lipid metabolism homeostasis and flexible energy metabolism in hypoxic environments.

Self-organization and fractality created by gluconeogenesis in the metabolic process [PDF]

Chaotic Modeling and Simulation, 2, pp.113-127 (2016), 2017
Within a mathematical model, the process of interaction of the metabolic processes such as glycolysis and gluconeogenesis is studied. As a result of the running of two opposite processes in a cell, the conditions for their interaction and the self-organization in a single dissipative system are created.

Molecular and cellular mechanisms underlying gyrate atrophy: Why is the retina primarily affected?

Acta Ophthalmologica, EarlyView.
Abstract Gyrate atrophy of the choroid and retina (GACR; OMIM #258870) is a rare early‐onset autosomal recessive disorder, caused by bi‐allelic pathogenic variants in the gene coding for ornithine aminotransferase (OAT) resulting in hyperornithinaemia.

Numerical simulation of growth of Escherichia coli in unsaturated porous media [PDF]

arXiv, 2014
A model for the aerobic and anaerobic growth of Escherichia coli (HB101 K12 pGLO) depending on the concentration of oxygen and DOC as substrate has been developed based on laboratory batch experiments. Using inverse modelling to obtain optimal sets of parameters, it could be shown that a model based on a modified double Contois kinetic can predict cell
