Effect of Repeated Movements on Motion Perception and Motor Learning of Dominant and Non-dominant Upper Extremity of Healthy Individuals

Bezmiâlem Science, 2021
Objective:Hand dominancy can be observed as right, left, or the usage of bilateral hands. Majority of the Turkish population are right-hand dominant. This study aimed to examine and interpret the motion perception and motor learning of the dominant and ...

Inspiration‐induced vasoconstrictive responses in dominant versus non‐dominant hands [PDF]

Clinical Physiology and Functional Imaging, 2005
SummarySingle rapid and deep inspirations (inspiratory gasps, IG) result in arteriolar vasoconstriction with concomitant transient decreases in skin blood flow that are most prominent in fingers and toes. Vascular responses (inspiratory gasp responses, IGR) are determined as the maximum percentage reduction in blood flow and have been used to assess ...

Vibration induced injuries in hands in long-term vibration exposed workers

Journal of Occupational Medicine and Toxicology, 2019
Introduction Long-term vibration exposure may cause neurophysiological disturbances such as numbness and tingling, reduced grip strength and difficulties in handling small objects.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Phonon-induced electron relaxation in weakly-confined single and coupled quantum dots [PDF]

, 2006
We investigate charge relaxation rates due to acoustic phonons in weakly-confined quantum dot systems, including both deformation potential and piezoelectric field interactions.

Reaction time and hand dominance

The Journal of Science and Medicine, 2021
In most individuals, there is a significant difference in hand dominance and this suggests that  sensorimotor tasks, such as reaction time, would demonstrate a difference in performance tasks conducted with dominant versus non-dominant hand. In this study, comparisons were made between the reaction time of the dominant to the nondominant hand, the ...

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Differences in muscle activity and intermuscular coordination between dominant and non-dominant hands during chopstick manipulation

Frontiers in Human Neuroscience
IntroductionTo develop an efficient rehabilitation program for patients with stroke to acquire fine motor skills such as chopstick manipulation, it is necessary to examine the differences in fundamental muscle functions between the hands during motor ...

Coherent phenomena in semiconductors

, 1997
A review of coherent phenomena in photoexcited semiconductors is presented. In particular, two classes of phenomena are considered: On the one hand the role played by optically-induced phase coherence in the ultrafast spectroscopy of semiconductors; On ...
