Hypernasality is one of the most detrimental speech disturbances that lead to declines of speech intelligibility. Velopharyngeal inadequacy, which is associated with anatomic defects such as cleft palate or neuromuscular disorders that affect velopharygneal function, is the primary cause of hypernasality. A simulation study by Rong and Kuehn [J. Speech Lang. Hear. Res. 55(5), 1438-1448 (2012)] demonstrated that properly adjusted oropharyngeal articulation can reduce nasality for vowels synthesized with an articulatory model [Mermelstein, J...

Filamin is a scaffolding protein that functions in many cells as an actin-crosslinker. FLN90, an isoform of the Drosophila ortholog Filamin/cheerio that lacks the actin-binding domain, is here shown to govern the growth of postsynaptic membrane folds and the composition of glutamate receptor clusters at the larval neuromuscular junction. Genetic and biochemical analyses revealed that FLN90 is present surrounding synaptic boutons. FLN90 is required in the muscle for localization of the kinase dPak and, downstream of dPak, for localization of the GTPase Ral and the exocyst complex to this region...

Hox genes are known to specify motoneuron pools in the developing vertebrate spinal cord and to control motoneuronal targeting in several species. However, the mechanisms controlling axial diversification of muscle innervation patterns are still largely unknown. We present data showing that the Drosophila Hox gene Ultrabithorax (Ubx) acts in the late embryo to establish target specificity of ventrally projecting RP motoneurons. In abdominal segments A2 to A7, RP motoneurons innervate the ventro-lateral muscles VL1-4, with VL1 and VL2 being innervated in a Wnt4-dependent manner...

: Synaptic vesicles fuse at morphological specializations in the presynaptic terminal termed active zones (AZs). Vesicle fusion can occur spontaneously or in response to an action potential. Following fusion, vesicles are retrieved and recycled within nerve terminals. It is still unclear whether vesicles that fuse spontaneously or following evoked release share similar recycling mechanisms. Genetic deletion of the SNARE-binding protein complexin dramatically increases spontaneous fusion, with the protein serving as the synaptic vesicle fusion clamp at Drosophila synapses...

Michael D Stubblefield
Radiation fibrosis syndrome describes the multiple neuromuscular, musculoskeletal, visceral, and other late effects that result from radiation-induced fibrosis. Radiation can damage the spinal cord, nerve roots, plexus, local peripheral nerves, and muscles within the radiation field. This constellation is known as a "myelo-radiculo-plexo-neuro-myopathy" and can result in pain, sensory loss, weakness, and other signs and symptoms. Although there is no curative treatment for radiation damage, supportive management of symptoms can be helpful in restoring and maintaining function and quality of life...

Christian M Custodio
With numerous advancements in early detection and multimodal therapy, cancer has become a chronic disease. As the number of cancer survivors continues to increase, physiatrists and other neuromuscular disease specialists are more likely to encounter individuals with residual impairments, disabilities, and/or handicaps resulting from cancer or related treatments. The patient with cancer is especially prone to injury directed at the peripheral nervous system at multiple anatomic levels. Electrodiagnosis is an invaluable tool in the evaluation of neuromuscular disorders in this patient population...

Typically, balance training has been used as an intervention paradigm either as static or as reactive balance training. Possible differences in functional outcomes between the two modalities have not been profoundly studied. The objective of the study was to investigate the specificity of neuromuscular adaptations in response to two balance intervention modalities within test and intervention paradigms containing characteristics of both profiles: classical sensorimotor training (SMT) referring to a static ledger pivoting around the ankle joint vs...

RNA-binding proteins (RBPs) acting at various steps in the post-transcriptional regulation of gene expression play crucial roles in neuronal development and synaptic plasticity. Genetic mutations affecting several RBPs and associated factors lead to diverse neurological symptoms, as characterized by neurodevelopmental and neuropsychiatric disorders, neuromuscular and neurodegenerative diseases, and can often be multisystemic diseases. We will highlight the physiological roles of a few specific proteins in molecular mechanisms of cytoplasmic mRNA regulation, and how these processes are dysregulated in genetic disease...

In skeletal muscles, levels and activity of Matrix MetalloProteinases (MMPs) and Tissue Inhibitors of MetalloProteinases (TIMPs) have been involved in myoblast migration, fusion and various physiological and pathological remodeling situations including neuromuscular diseases. This has opened perspectives for the use of MMPs' overexpression to improve the efficiency of cell therapy in muscular dystrophies and resolve fibrosis. Alternatively, inhibition of individual MMPs in animal models of muscular dystrophies has provided evidence of beneficial, dual or adverse effects on muscle morphology or function...

OBJECTIVE: Rocuronium is a non-depolarising, intermediate-acting, monoquaternary amino steroid and was brought into clinical use as a potentially ideal muscle relaxant. Post-operative residual curarisation (PORC) results from the prolonged effects of non-depolarising neuromuscular blocking agents. This is a common problem and seriously affects patient safety. No recent study has investigated the effects of sugammadex on smokers, which is often used to restore neuromuscular block and avoid PORC...

It is a truism that care of the patient with an acutely severe neurologic illness starts with a full neurologic examination. Neurologic examination is followed by tests (neuroimaging and laboratory) resulting in a diagnosis (presumptive or definitive) and treatment (definitive or preemptive) and followed by admission for supportive care and more treatment. The sequence of decisions depends on the diagnosis, but treatment may be needed to diagnose a neurologic disorder. To find out what underlies the acute presentation of certain neurologic conditions requires (1) interpretation of neurologic findings, (2) interpretation of neuroimaging, (3) linking laboratory abnormalities to certain clinical neurologic findings, and (4) evaluation of improvement or refractoriness after treatment...

The muscular dystrophies are a diverse group of degenerative diseases for which many mouse models are available. These models are frequently used to assess potential therapeutic interventions and histological evaluation of multiple muscles is an important part of this assessment. Histological evaluation is especially useful when combined with tests of muscle function. This unit describes a protocol for necropsy, processing, cryosectioning, and histopathological evaluation of murine skeletal muscles, which is applicable to both models of muscular dystrophy and other neuromuscular conditions...

BACKGROUND: The greater susceptibility to contraction-induced skeletal muscle injury (fragility) is an important dystrophic feature and tool for testing preclinic dystrophin-based therapies for Duchenne muscular dystrophy. However, how these therapies reduce the muscle fragility is not clear. METHODS: To address this question, we first determined the event(s) of the excitation-contraction cycle which is/are altered following lengthening (eccentric) contractions in the mdx muscle...

BACKGROUND: Cholinergic dysfunction occurs during aging and in a variety of diseases, including amyotrophic lateral sclerosis (ALS). However, it remains unknown whether changes in cholinergic transmission contributes to age- and disease-related degeneration of the motor system. Here we investigated the effect of moderately increasing levels of synaptic acetylcholine (ACh) on the neuromuscular junction (NMJ), muscle fibers, and motor neurons during development and aging and in a mouse model for amyotrophic lateral sclerosis (ALS)...
