Predominant orientation of local muscular load to proximal or distal portions of shoulders and upper limbs considerably influences features of changes in brain functions and blood supply. Characteristic for plasterers, localization of myogeloses in upper part of trapezium muscles causes not only impaired vertebrobasillar circulation, but also venous cerebral stasis and caudal medullar dysfunction. Clinical symptoms are vestibular disorders, depressed functions of hearing, chronic venous cerebral congestion, posture-tonic disorders. Local loads on distal portions of limbs have other mechanisms of cerebral and peripheral disorders.

Measurement Properties of the Friedreich Ataxia Rating Scale in Patients with Spinocerebellar Ataxia.

Introduction: The Friedreich Ataxia Rating Scale-Activities of Daily Living (FARS-ADL) is a valid, highly utilized measure for assessing ADL impacts in patients with Friedreich ataxia. We provide evidence of the psychometric validity of the FARS-ADL in two cohorts of patients with spinocerebellar ataxia (SCA).
Methods: Using data from a cohort of real-world subjects with SCA (recruited at Massachusetts General Hospital [MGH]; n = 33) and a phase 3 trial of troriluzole in adults with SCA (NCT03701399 [Study 206]; n = 217), comprising a subset of patients with the SCA3 genotype (n = 89), the psychometric measurement properties and minimal change thresholds of the FARS-ADL were examined.

During skeletal muscle unloading, phosphoinositide 3-kinase (PI3K), and especially PI3K gamma (PI3Kγ), can be activated by changes in membrane potential. Activated IP3 can increase the ability of Ca to enter the nucleus through IP3 receptors. This may contribute to the activation of transcription factors that initiate muscle atrophy processes.

Duchenne muscular dystrophy (DMD) is a severe X-linked genetic disorder caused by an array of mutations in the dystrophin gene, with the most commonly mutated regions being exons 48-55. One of the several existing approaches to treat DMD is gene therapy, based on alternative splicing and mutant exon skipping. Testing of such therapy requires animal models that carry mutations homologous to those found in human patients.

Inefficient targeting of muscle stem cells (MuSCs), also called satellite cells, represents a major bottleneck of current therapeutic strategies for muscular dystrophies, as it precludes the possibility of promoting compensatory regeneration. Here we describe a muscle-targeting delivery platform, based on gold nanoparticles, that enables the release of therapeutic oligonucleotides into MuSCs. We demonstrate that AuNPs conjugation to an aptamer against α7/β1 integrin dimers directs either local or systemic delivery of microRNA-206 to MuSCs, thereby promoting muscle regeneration and improving muscle functionality, in a mouse model of Duchenne Muscular Dystrophy.

Hirayama disease, also known as non-progressive juvenile spinal muscular atrophy of the upper limbs, brachial monomelic amyotrophy, or benign focal atrophy, affects the C7 D1 myotomes; an electromyogram (EMG) shows neurogenic damage in the C7-C8-T1 territories. It causes weakness and amyotrophy of the distal upper limb. Although it usually occurs on one side only, bilateral symmetric cases of Hirayama disease have occasionally been described.
