The Role of Hydrogen Peroxide in Redox-Dependent Signaling: Homeostatic and Pathological Responses in Mammalian Cells

open access: yesCells, 2018
Hydrogen peroxide (H2O2) is an important metabolite involved in most of the redox metabolism reactions and processes of the cells. H2O2 is recognized as one of the main molecules in the sensing, modulation and signaling of redox metabolism, and it is ...

A tale of two inositol trisphosphates. [PDF]

open access: yes, 2016
Between spring 1982 and autumn 1984 the physiological role of Ins(1,4,5)P3 as a calcium-mobilizing second messenger was first suggested and then experimentally established.

Origin of symbol-using systems: speech, but not sign, without the semantic urge [PDF]

open access: yes, 2014
Natural language—spoken and signed—is a multichannel phenomenon, involving facial and body expression, and voice and visual intonation that is often used in the service of a social urge to communicate meaning.

3-Econsystems: microRNAs, receptors, and latent viruses; some insights biology can gain from economic theory

open access: yesFrontiers in Microbiology, 2016
This mini-review describes three biological systems. All three include competing molecules and a limiting molecule that binds the competing molecules. Such systems are extensively researched by economists.

Event-based simulation of quantum physics experiments [PDF]

open access: yes, 2014
We review an event-based simulation approach which reproduces the statistical distributions of wave theory not by requiring the knowledge of the solution of the wave equation of the whole system but by generating detection events one-by-one according to ...

The Response of Cupriavidus metallidurans CH34 to Cadmium Involves Inhibition of the Initiation of Biofilm Formation, Decrease in Intracellular c-di-GMP Levels, and a Novel Metal Regulated Phosphodiesterase

open access: yesFrontiers in Microbiology, 2019
Cadmium is a highly toxic heavy metal for biological systems. Cupriavidus metallidurans CH34 is a model strain to study heavy metal resistance and bioremediation as it is able to deal with high heavy metal concentrations. Biofilm formation by bacteria is

A Scalable Model of Cerebellar Adaptive Timing and Sequencing: The Recurrent Slide and Latch (RSL) Model [PDF]

open access: yes, 2000
From the dawn of modern neural network theory, the mammalian cerebellum has been a favored object of mathematical modeling studies. Early studies focused on the fan-out, convergence, thresholding, and learned weighting of perceptual-motor signals within ...
