Coulomb Interaction as the Source of Muscle Force [PDF]

open access: yesarXiv, 2007
Myosin motor is the machine, which performs mechanical work in the course of adenosine triphosphate molecule hydrolysis and myosin head conformations accompanying this process. For displacement of individual fragments of large molecule relative to each other to arise and work to be performed, force must be born inside protein.

Differential gene expression in Chorthippus parallelus (Zetterstedt, 1821) (Orthoptera: Acrididae: Gomphocerinae) induced by Wolbachia infection

open access: yesInsect Science, EarlyView.
Distinct lineages of the grasshopper Chorthippus parallelus (Orthoptera: Acrididae) form a well‐known hybrid zone (HZ) in the Pyrenees mountain range; the Iberian endemism C. p. erythropus (Cpe) and the subspecies C. p. parallelus, (Cpp) widely distributed throughout the rest of Europe. Both subspecies differ in diverse traits, including the strains of

Assignments of backbone 1H, 13C and 15N resonances in H-Ras (1–166) complexed with GppNHp at physiological pH [PDF]

open access: yes, 2012
The small GTPase Ras is an important signaling molecule acting as a molecular switch in eukaryotic cells. Recent findings of global conformational exchange and a putative allosteric binding site in the G domain of Ras opened an avenue to understanding ...

Genetic and Pharmacological Inhibition of Metabotropic Glutamate Receptor Signalling Extends Lifespan in Drosophila

open access: yesAging Cell, EarlyView.
We show that genetic and pharmacological inhibition of the metabotropic glutamate receptor, DmGluRA extends Drosophila lifespan, improves stress tolerance and alters early‐life locomotion. Several markers indicative of reduced ribosomal biogenesis, a hallmark of longevity, were also detected in these flies.

Pilot study of electrochemical reduction of selected nucleotides and double-stranded DNA at pristine micro-/ultrananocrystalline boron-doped diamond electrodes at very negative potentials [PDF]

open access: yes
Pristine polycrystalline boron-doped diamond electrodes (BDDEs) -- microcrystalline (B-MCDE) and ultrananocrystalline (B-UNCDE) were applied for the electrochemical reduction of several selected purine nucleotides -- Guanosine 5'-monophosphate (GMP), 2'-Deoxyguanosine 5'-monophosphate (dGMP), Adenosine 5'-monophosphate (AMP), Adenosine 5'-diphosphate ...

Active transport: A kinetic description based on thermodynamic grounds [PDF]

open access: yesarXiv, 2004
We show that active transport processes in biological systems can be understood through a local equilibrium description formulated at the mesoscale, the scale to describe stochastic processes. This new approach uses the method established by nonequilibrium thermodynamics to account for the irreversible processes occurring at this scale and provides ...
