The effect of a modified elastic band orthosis on gait and balance in stroke survivors.

Background: Gait is crucial for independent living for stroke survivors and assistive devices have been developed to support gait performance. Ankle foot orthosis (AFOs) are commonly provided to stroke survivors to prevent foot drop during walking. However, previous studies have reported limitations of AFOs including them being too heavy, creating skin irritation, and being a stigma of disability.

Knowledge and Perceptions about COVID-19 among Thai Classical Dancers in Thailand: An Online Cross-Sectional Survey.

The prevention and control of the spread of COVID-19 has become a major challenge and concern globally. Since the COVID-19 pandemic is still ongoing, sufficient knowledge and practices of people toward COVID-19 is necessary. Thai classical dancers are one of the groups affected by the pandemic.

Greater Star Excursion Balance Test Performance in Thai Khon Masked Dancers Versus Nondancers.

The Khon masked dance drama is an authentic Thai classical performance that has been handed down for centuries. The performance has many unique choreographic patterns that are typical of the Southeast Asian performing arts. The Thai Khon masked dance consists of a combination of balance control and limb movement in different rhythms.

Anatomical variants identified on chest computed tomography of 1000+ COVID-19 patients from an open-access dataset.

Chest computed tomography (CT) has been the preferred imaging modality during the pandemic owing to its sensitivity in detecting COVID-19 infections. Recently, a large number of COVID-19 imaging datasets have been deposited in public databases, leading to rapid advances in COVID-19 research. However, the application of these datasets beyond COVID-19-related research has been little explored.

Noise Exposures Causing Hearing Loss Generate Proteotoxic Stress and Activate the Proteostasis Network.

Exposure to excessive sound causes noise-induced hearing loss through complex mechanisms and represents a common and unmet neurological condition. We investigate how noise insults affect the cochlea with proteomics and functional assays. Quantitative proteomics reveals that exposure to loud noise causes proteotoxicity.

Effects of melatonin on severe crush spinal cord injury-induced reactive astrocyte and scar formation.

The present work aimed at analyzing the effects of melatonin on scar formation after spinal cord injury (SCI). Upregulation of reactive astrocyte under SCI pathological conditions has been presented in several studies. It has been proved that the crucial factor in triggering this upregulation is proinflammatory cytokines.

Comparison of Balance Performance Between Thai Classical Dancers and Non-Dancers.

Thai classical dance is a traditional dramatic art, the technique of which has many features in common with South East Asian performing art. The choreographic patterns consist of various forms of balance control together with limb movements in slow rhythm. The grace and beauty of the dancer are dependent on how well the limb movements curve and angle.

Biomedical and clinical promises of human pluripotent stem cells for neurological disorders.

Neurological disorders are characterized by the chronic and progressive loss of neuronal structures and functions. There is a variability of the onsets and causes of clinical manifestations. Cell therapy has brought a new concept to overcome brain diseases, but the advancement of this therapy is limited by the demands of specialized neurons.

Restoration of auditory evoked responses by human ES-cell-derived otic progenitors.

Deafness is a condition with a high prevalence worldwide, produced primarily by the loss of the sensory hair cells and their associated spiral ganglion neurons (SGNs). Of all the forms of deafness, auditory neuropathy is of particular concern. This condition, defined primarily by damage to the SGNs with relative preservation of the hair cells, is responsible for a substantial proportion of patients with hearing impairment.

Stem cell based therapy in the inner ear: appropriate donor cell types and routes for transplantation.

Losing one of our main sensory systems such as hearing can have devastating consequences in the way we interact with the world. The main problem lies in the fact that the critical sensory cells, the auditory neurons and hair cells located in the cochlea are only generated during development and, when damaged, cannot be replaced. The options currently available to treat this condition are very limited, and are mostly represented by prosthetic devices such as hearing aids and cochlear implants.

The existence of opioid receptors in the cochlea of guinea pigs.

Several independent investigations have demonstrated the presence of opioid peptides in the inner ear organ of Corti and in particular in the efferent nerve fibers innervating the cochlear hair cells. However, the precise innervation pattern of opioid fibers remains to be investigated. In the present study the expression of opioid receptors and their peptides is demonstrated in young adult guinea pig cochlea.

Opioid modulation of GABA release in the rat inferior colliculus.

Background: The inferior colliculus, which receives almost all ascending and descending auditory signals, plays a crucial role in the processing of auditory information. While the majority of the recorded activities in the inferior colliculus are attributed to GABAergic and glutamatergic signalling, other neurotransmitter systems are expressed in this brain area including opiate peptides and their receptors which may play a modulatory role in neuronal communication.

Results: Using a perfusion protocol we demonstrate that morphine can inhibit KCl-induced release of [3H]GABA from rat inferior colliculus slices.

The presence of opioid receptors in rat inner ear.

Opioid peptides have been identified in the inner ear but relatively little information is available about the expression and distribution of their receptors. The aim of the present study was therefore to identify and localize the mu (MOR), delta (DOR) and kappa (KOR) opioid receptor subtypes within the rat cochlea. The expression of these opioid receptor subtypes was determined by reverse transcriptase-polymerase chain reaction followed by nested polymerase chain reaction analysis.
