Antisense oligonucleotides (AONs) hold promise for therapeutic splice-switching correction in many genetic diseases. However, despite advances in AON chemistry and design, systemic use of AONs is limited due to poor tissue uptake and sufficient therapeutic efficacy is still difficult to achieve. A novel class of AONs made of tricyclo-DNA (tcDNA) is considered very promising for the treatment of Duchenne muscular dystrophy (DMD), a neuromuscular disease typically caused by frameshifting deletions or nonsense mutations in the gene-encoding dystrophin and characterized by progressive muscle weakness, cardiomyopathy, and respiratory failure in addition to cognitive impairment...

Primycin-sulphate is a highly effective compound against Gram (G) positive bacteria. It has a potentially synergistic effect with vancomycin and statins which makes primycin-sulphate a potentially very effective preparation. Primycin-sulphate is currently used exclusively in topical preparations such as in in vitro animal hepatocyte and neuromuscular junction studies (in mice, rats, snakes, frogs) as well as in in vitro human red blood cell experiments. During these studies, the use of primycin-sulphate resulted in reduced cellular membrane integrity and modified ion channel activity...

BACKGROUND: Myasthenia gravis (MG) is an uncommon autoimmune disorder affecting the neuromuscular junction and manifesting as muscle weakness. A multitude of stressors can exacerbate MG. When symptoms are exacerbated, muscle weakness can be severe enough to result in respiratory failure, a condition known as myasthenic crisis (MC). OBJECTIVE: This review discusses risk factors, diagnosis, management, and iatrogenic avoidance of MC. DISCUSSION: MC can affect any age, ethnicity, or sex and can be precipitated with any stressor, infection being the most common...

Human induced-pluripotent stem cells (iPSCs) are a promising resource for propagation of myogenic progenitors. Our group recently reported a unique protocol for the derivation of myogenic progenitors directly (without genetic modification) from human pluripotent cells using free-floating spherical culture. Here we expand our previous efforts and attempt to determine how differentiation duration, culture surface coatings, and nutrient supplements in the medium influence progenitor differentiation and formation of skeletal myotubes containing sarcomeric structures...

Marianne de Visser, David J Oliver
PURPOSE OF REVIEW: Palliative care is an approach that improves the quality of life of patients and their families facing the problem associated with life-threatening illness. Neuromuscular disorders (NMDs) are characterized by progressive muscle weakness, leading to pronounced and incapacitating physical disabilities. Most NMDs are not amenable to curative treatment and would thus qualify for palliative care. Amyotrophic lateral sclerosis is a relentlessly progressive disease, which leads to death about 2 years after onset due to respiratory muscle weakness...

Facemask ventilation of the lungs can be an important rescue intervention in a 'cannot intubate' scenario. We assessed the effect of neuromuscular blockade on expiratory tidal volumes in patients with expected difficulty in mask ventilation. The lungs of patients with at least three predictors of difficulty in mask ventilation were ventilated using a facemask held with two hands, with mechanical ventilation set in a pressure-controlled mode. Tidal volumes were recorded before and after the establishment of complete neuromuscular block...

The appropriate use of medications during Emergency Neurological Life Support (ENLS) is essential to optimize patient care. Important considerations when choosing the appropriate agent include the patient's organ function and medication allergies, potential adverse drug effects, drug interactions and critical illness and aging pathophysiologic changes. Critical medications used during ENLS include hyperosmolar therapy, anticonvulsants, antithrombotics, anticoagulant reversal and hemostatic agents, anti-shivering agents, neuromuscular blockers, antihypertensive agents, sedatives, vasopressors and inotropes, and antimicrobials...

BACKGROUND: Many injuries of the lower extremities, especially the knee and ankle, occur during sports activity, and the incidence rate is higher in women than in men. HYPOTHESIS: The hypothesis was that phases of the menstrual cycle affect the width of the tibiofibular syndesmosis during drop landing in healthy young women and that such changes at the tibiofibular joint also affect the dynamics and neuromuscular coordination of the lower extremities. STUDY DESIGN: Descriptive laboratory study...

Alpine ski racing is known to be a sport with a high risk of injuries. Because most studies have focused mainly on top-level athletes and on traumatic injuries, limited research exists about injury risk factors among youth ski racers. The aim of this study was to determine the intrinsic risk factors (anthropometrics, biological maturity, physical fitness, racing technique) for injury among youth alpine ski racers. Study participants were 81 youth ski racers attending a ski boarding school (50 males, 31 females; 9-14 years)...

BACKGROUND: Micro-instability (non-radiographic clinical instability) continues to gain recognition as a problem at the hip. Although most research has been directed to anterior hip instability, posterior hip instability (PHI) has also garnered attention. PHI is under recognized, difficult to identify, and confused with other hip pathologies such as a simple sprain or strain. A novel clinical test is introduced that may have helped identify PHI in this patient. Additionally, a conservative rehabilitation approach emphasizing stabilization exercises is described...

The neuroligin (Nlg) family of neural cell adhesion molecules is thought to be required for synapse formation and development, and has been linked to the development of autism spectrum disorders in humans. In Drosophila melanogaster, mutations in the neuroligin 1-3 genes have been reported to induce synapse developmental defects at neuromuscular junctions (NMJs), but the role of neuroligin 4 (dnlg4) in synapse development has not been determined. Here, we report that the Drosophila neuroligin 4 (DNlg4) is different from DNlg1-3 that it presynaptically regulates NMJ synapse development...
