Muscle contraction. [PDF]

open access: yesNovartis Foundation symposium, 1998
Understanding muscle contraction goes to the heart of one of the fundamental questions posed by classical philosophy, namely the nature of the pi nu epsilon upsilon mu alpha psi nu chi iota kappa omicron nu. The nature of 'understanding' has altered greatly during the last two millenia, particularly in response to the development of the concept of ...

The Intriguing Dual Lattices of the Myosin Filaments in Vertebrate Striated Muscles: Evolution and Advantage

open access: yesBiology, 2014
Myosin filaments in vertebrate striated muscle have a long roughly cylindrical backbone with cross-bridge projections on the surfaces of both halves except for a short central bare zone. In the middle of this central region the filaments are cross-linked

The Interacting Head Motif Structure Does Not Explain the X-Ray Diffraction Patterns in Relaxed Vertebrate (Bony Fish) Skeletal Muscle and Insect (Lethocerus) Flight Muscle

open access: yesBiology, 2019
Unlike electron microscopy, which can achieve very high resolution but to date can only be used to study static structures, time-resolved X-ray diffraction from contracting muscles can, in principle, be used to follow the molecular movements involved in ...

The p21‐activated kinase 2 (PAK2), but not PAK1, regulates contraction‐stimulated skeletal muscle glucose transport

open access: yesPhysiological Reports, 2020
Aim Muscle contraction stimulates skeletal muscle glucose transport. Since it occurs independently of insulin, it is an important alternative pathway to increase glucose transport in insulin‐resistant states, but the intracellular signaling mechanisms ...

Voluntary Muscle Contraction Detection Algorithm Based on LSTM for Muscle Quality Measurement Algorithm

open access: yesApplied Sciences, 2021
In this paper, we propose the long–short-term memory (LSTM)-based voluntary and non-voluntary (VNV) muscle contraction classification algorithm in an electrical stimulation (ES) environment.

Isometric contraction induces transient increase of REDD1 expression in non‐contracted muscles partly through glucocorticoids

open access: yesPhysiological Reports, 2023
This study investigated whether muscle contraction induces expression of regulated in development and DNA damage 1 (REDD1), a potent inhibitor of mTORC1, in mice muscle.

Stable isotope-labeled carnitine reveals its rapid transport into muscle cells and acetylation during contraction

open access: yesHeliyon, 2023
Carnitine plays multiple roles in skeletal muscle metabolism, including fatty acid transport and buffering of excess acetyl-CoA in the mitochondria. The skeletal muscle cannot synthesize carnitine; therefore, carnitine must be taken up from the blood ...
