ADP-dependent Phosphofructokinases in Mesophilic and Thermophilic Methanogenic Archaea [PDF]

open access: yes, 2001
Phosphofructokinase (PFK) is a key enzyme of the glycolytic pathway in all domains of life. Two related PFKs, ATP-dependent and PPi-dependent PFK, have been distinguished in bacteria and eucarya, as well as in some archaea.

Intertwined electron-nuclear motion in frustrated double ionization in driven heteronuclear molecules [PDF]

open access: yes, 2017
We study frustrated double ionization in a strongly-driven heteronuclear molecule HeH$^{+}$ and compare with H$_2$. We compute the probability distribution of the sum of the final kinetic energies of the nuclei for strongly-driven HeH$^{+}$. We find that

Decreased Ficolin-3-mediated Complement Lectin Pathway Activation and Alternative Pathway Amplification During Bacterial Infections in Patients With Type 2 Diabetes Mellitus

open access: yesFrontiers in Immunology, 2019
Bacterial infections are frequent and severe in patients with diabetes mellitus. Whether diabetes per se induces functional alterations in the complement system hampering activation during infection is unknown.

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.

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 ...

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 ...

Peripheral and central mechanisms involved in hormonal control of male and female reproduction [PDF]

open access: yes, 2016
Reproduction involves the integration of hormonal signals acting across multiple systems togenerate a synchronized physiological output. A critical component of reproduction is the luteinizinghormone (LH) surge, which is mediated by estradiol (E2) and ...

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.

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.

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.
