Frustrated double ionization in two-electron triatomic molecules [PDF]

open access: yes, 2016
Using a semi-classical model, we investigate frustrated double ionization (FDI) in $\mathrm{D_3^+}$, a two-electron triatomic molecule, when driven by an intense, linearly polarized, near-infrared (800 nm) laser field.

Is the A-Chain the Engine That Drives the Diversity of C1q Functions? Revisiting Its Unique Structure

open access: yesFrontiers in Immunology, 2018
The immunopathological functions associated with human C1q are still growing in terms of novelty, diversity, and pathologic relevance. It is, therefore, not surprising that C1q is being recognized as an important molecular bridge between innate and ...

Associative memory stored by functional novel pathway rather than modifications of preexisting neuronal pathways [PDF]

open access: yes, 2006
Associative conditioning involves changes in the processing pathways activated by sensory information to link the conditioned stimulus (CS) to the conditioned behavior.

The basal ganglia, the ideal machinery for the cost-benefit analysis of action plans [PDF]

open access: yes, 2013
Basal ganglia dysfunction causes profound movement disorders, often attributed to imbalance between direct and indirect pathway activity in the sensorimotor basal ganglia.

Complement-coagulation cross-talk: a potential mediator of the physiological activation of complement by low pH

open access: yesFrontiers in Immunology, 2015
The complement system is a major constituent of the innate immune system. It not only bridges innate and adaptive arms of the immune system but also links the immune system with the coagulation system.

Targeting the non-classical estrogen pathway in neurodegenerative diseases and brain injury disorders

open access: yesFrontiers in Endocrinology, 2022
Estrogens can alter the biology of various tissues and organs, including the brain, and thus play an essential role in modulating homeostasis. Despite its traditional role in reproduction, it is now accepted that estrogen and its analogues can exert ...

Chimeric Proteins Containing MAP-1 and Functional Domains of C4b-Binding Protein Reveal Strong Complement Inhibitory Capacities

open access: yesFrontiers in Immunology, 2018
The complement system is a tightly regulated network of proteins involved in defense against pathogens, inflammatory processes, and coordination of the innate and adaptive immune responses.

Is there a classical nonsense-mediated decay pathway in trypanosomes? [PDF]

open access: yesPLoS ONE, 2011
In many eukaryotes, messenger RNAs with premature termination codons are destroyed by a process called "nonsense-mediated decay", which requires the RNA helicase Upf1 and also, usually, an interacting factor, Upf2.

Classical analysis of correlated multiple ionization in strong fields

open access: yes, 2000
We discuss the final stages of the simultaneous ionization of two or more electrons due to a strong laser pulse. An analysis of the classical dynamics suggests that the dominant pathway for non-sequential escape has the electrons escaping in a symmetric ...

Inflammasomes and Fibrosis

open access: yesFrontiers in Immunology, 2021
Fibrosis is the final common pathway of inflammatory diseases in various organs. The inflammasomes play an important role in the progression of fibrosis as innate immune receptors.
