Semaphorin7A: its role in the control of serotonergic circuits and functional recovery following spinal cord injury

open access: yesNeural Regeneration Research, 2022
Serotonin is a monoamine neurotransmitter synthetized in various populations of brainstem neurons. In the spinal cord, descending serotonergic projections regulate postural muscle tone, locomotion and rhythm and coordination of movements via the Central ...

Bounding the Equilibrium Distribution of Markov Population Models [PDF]

open access: yes, 2010
Arguing about the equilibrium distribution of continuous-time Markov chains can be vital for showing properties about the underlying systems. For example in biological systems, bistability of a chemical reaction network can hint at its function as a ...

Triboelectric-induced ion mobility for artificial intelligence-enhanced mid-infrared gas spectroscopy

open access: yesNature Communications, 2023
Isopropyl alcohol molecules, as a biomarker for anti-virus diagnosis, play a significant role in the area of environmental safety and healthcare relating volatile organic compounds. However, conventional gas molecule detection exhibits dramatic drawbacks,

Generative Pre-Training from Molecules [PDF]

open access: yes, 2021
SMILES is a line notation for entering and representing molecules. Being inherently a language construct, it allows estimating molecular data in a self-supervised fashion by employing machine learning methods for natural language processing (NLP).

Dynamic disorder in simple enzymatic reactions induces stochastic amplification of substrate [PDF]

open access: yes, 2017
A growing amount of evidence points to the fact that many enzymes exhibit fluctuations in their catalytic activity, which are associated with conformational changes on a broad range of timescales. The experimental study of this phenomenon, termed dynamic

Antenna molecule drives solar hydrogen generation [PDF]

open access: yesProceedings of the National Academy of Sciences, 2015
It would be convenient if gigantic reservoirs of molecular hydrogen H2(g) existed in the earth’s crust that could be safely tapped as an energy source. Instead, most hydrogen found near the earth’s surface is bound up in water as protons, H+(aq) that must be reduced before utilization as a fuel (1). When the electrons for proton reduction come from the

Stochastic model for cell polarity

open access: yes, 2012
Cell polarity refers to the spatial asymmetry of molecules on the cell membrane. Altschuler, Angenent, Wang and Wu have proposed a stochastic model for studying the emergence of polarity in the presence of feedback between molecules.
