An autonomous molecular transport system using DNAs and motor proteins in molecular communication [PDF]

open access: yes2007 2nd Bio-Inspired Models of Network, Information and Computing Systems, 2007
This paper describes a molecular transport system in molecular communication that uses the machinery in living cells. The molecular transport system requires: 1) loading of the specified cargo molecules at a loading site (at a sender); 2) transport of the loaded cargoes to an unloading site (to a receiver); and 3) unloading of the transported cargoes ...

Molecular Imaging of Microglial Activation in Amyotrophic Lateral Sclerosis [PDF]

open access: yes, 2012
There is growing evidence of activated microglia and inflammatory processes in the cerebral cortex in amyotrophic lateral sclerosis (ALS). Activated microglia is characterized by increased expression of the 18 kDa translocator protein (TSPO) in the brain

Low-frequency transcranial magnetic stimulation is beneficial for enhancing synaptic plasticity in the aging brain

open access: yesNeural Regeneration Research, 2015
In the aging brain, cognitive function gradually declines and causes a progressive reduction in the structural and functional plasticity of the hippocampus. Transcranial magnetic stimulation is an emerging and novel neurological and psychiatric tool used

The Architectural Dynamics of the Bacterial Flagellar Motor Switch

open access: yesBiomolecules, 2020
The rotary bacterial flagellar motor is remarkable in biochemistry for its highly synchronized operation and amplification during switching of rotation sense. The motor is part of the flagellar basal body, a complex multi-protein assembly.

Mesenchymal stem cells-based therapy as a potential treatment in neurodegenerative disorders: is the escape from senescence an answer?

open access: yesNeural Regeneration Research, 2015
Aging is the most prominent risk factor contributing to the development of neurodegenerative disorders. In the United States, over 35 million of elderly people suffer from age-related diseases.

Gene profiling of identified neurons to dissect molecular mechanisms involved in spinal reflex assembly [PDF]

open access: yes, 2010
The central question during my PhD studies was to understand the molecular mechanisms and genetic cascades controlling the sequential specification of distinct classes of dorsal root ganglia (DRG) sensory neurons, with a particular focus on genes ...

N-Propionylmannosamine stimulates axonal elongation in a murine model of sciatic nerve injury

open access: yesNeural Regeneration Research, 2015
Increasing evidence indicates that sialic acid plays an important role during nerve regeneration. Sialic acids can be modified in vitro as well as in vivo using metabolic oligosaccharide engineering of the N-acyl side chain.

Biological conduits combining bone marrow mesenchymal stem cells and extracellular matrix to treat long-segment sciatic nerve defects

open access: yesNeural Regeneration Research, 2015
The transplantation of polylactic glycolic acid conduits combining bone marrow mesenchymal stem cells and extracellular matrix gel for the repair of sciatic nerve injury is effective in some respects, but few data comparing the biomechanical factors ...

An experimental study of the putative mechanism of a synthetic autonomous rotary DNA nanomotor [PDF]

open access: yesRoyal Society Open Science, 2017
DNA has been used to construct a wide variety of nanoscale molecular devices. Inspiration for such synthetic molecular machines is frequently drawn from protein motors, which are naturally occurring and ubiquitous.

Molecular motors in nanobiotechnology: Protein and DNA based molecular motors: A review

open access: yesResults in Chemistry
Molecular motor can be defined as the collection of a separate number of molecular features (that is, a supramolecular structure) which has been developed to carry out a function through the mechanical movements of its components, which occurs when it is appropriately stimulated externally. Therefore, molecular motors include a part with a motor, which
