A Systematic and a Scoping Review on the Psychometrics and Clinical Utility of the Volume-Viscosity Swallow Test (V-VST) in the Clinical Screening and Assessment of Oropharyngeal Dysphagia

open access: yesFoods, 2021
(1) Background: The volume-viscosity swallow test (V-VST) is a clinical tool for screening and diagnosis of oropharyngeal dysphagia (OD). Our aims were to examine the clinical utility of the V-VST against videofluoroscopy (VFS) or fiberoptic endoscopic ...

Objective assessment of eye alignment and disparity-driven vergence in Parkinson’s disease

open access: yesFrontiers in Aging Neuroscience, 2023
BackgroundSelf-reported diplopia is described in up to one-third of Parkinson’s disease (PD) patients.ObjectiveThe purpose of our study was to expand our understanding of the mechanistic underpinnings of diplopia in PD. We hypothesize that the time-based

Loss of Unconventional Myosin VI Affects cAMP/PKA Signaling in Hindlimb Skeletal Muscle in an Age-Dependent Manner

open access: yesFrontiers in Physiology, 2022
Myosin VI (MVI) is a unique unconventional myosin ubiquitously expressed in metazoans. Its diverse cellular functions are mediated by interactions with a number of binding partners present in multi-protein complexes.

A new interpretation and quantitative method for diplopia test: 304 cases of ocular motor nerve palsy for clinical test and verify [PDF]

open access: yesInternational Journal of Ophthalmology, 2017
We introduce a new interpretation and quantitative method for computerized diplopia test. By comparing this new method to the Hess screen test, we validate its applicability among 304 patients with ocular motor nerve palsy.

How myosin VI traps its off-state, is activated and dimerizes

open access: yesNature Communications, 2023
Myosin VI (Myo6) is the only minus-end directed nanomotor on actin, allowing it to uniquely contribute to numerous cellular functions. As for other nanomotors, the proper functioning of Myo6 relies on precise spatiotemporal control of motor activity via ...

A Unifying Model-Based Hypothesis for the Diverse Waveforms of Infantile Nystagmus Syndrome

open access: yesJournal of Eye Movement Research, 2011
We expanded the original behavioral Ocular Motor System (OMS) model for Infantile Nystagmus Syndrome (INS) by incorporating common types of jerk waveforms within a unifying mechanism.

Mechanistic and structural basis for activation of cardiac myosin force production by omecamtiv mecarbil

open access: yesNature Communications, 2017
Omecamtiv mecarbil (OM) is a cardiac myosin activator that is currently in clinical trials for heart failure treatment. Here, the authors give insights into its mode of action and present the crystal structure of OM bound to bovine cardiac myosin, which ...

Formation of Aberrant Myotubes by Myoblasts Lacking Myosin VI Is Associated with Alterations in the Cytoskeleton Organization, Myoblast Adhesion and Fusion

open access: yesCells, 2020
We have previously postulated that unconventional myosin VI (MVI) could be involved in myoblast differentiation. Here, we addressed the mechanism(s) of its involvement using primary myoblast culture derived from the hindlimb muscles of Snell’s waltzer ...

Myosin 7 and its adaptors link cadherins to actin

open access: yesNature Communications, 2017
Cadherin is essential for mechanotransduction and myosin-adaptor-harmonin complexes anchor it to actin. Here the authors present the structures of myosin 7 MF2 domains bound to the harmonin PDZ3c domain and give insights into myosin-adaptor-harmonin ...

Transmembrane Protein 100 Inhibits the Progression of Colorectal Cancer by Promoting the Ubiquitin/Proteasome Degradation of HIF-1α

open access: yesFrontiers in Oncology, 2022
Transmembrane protein 100 (TMEM100) is involved in embryonic cardiovascular system development. However, the biological role of TMEM100 in human cancers, particularly colorectal cancer (CRC), is unclear.
