The contribution of (R)-enantiomer of N-methyl-salsolinol (1,2-dimethyl-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline; NMSal) to the degeneration of dopaminergic neurons in the course of Parkinson's disease (PD) has been predominantly suggested by in vitro experiments in cell culture and by an in vivo study in which this compound has been directly injected(More)
BAG3 belongs to BAG family of molecular chaperone regulators interacting with HSP70 and anti-apoptotic protein Bcl-2. It is ubiquitously expressed with strong expression in skeletal and cardiac muscle, and is involved in a panoply of cellular processes. Mutations in BAG3 and aberrations in its expression cause fulminant myopathies, presenting with(More)
This study was aimed at assessing the contribution of reflex and non-reflex factors to the muscle tone of old female Wistar rats. The hind foot of a rat was flexed or extended at the ankle joint by 25 degrees over 250 ms. The resistance of the foot to passive movements (torque, mechanomyogram), as well as the reflex electromyographic activity in the(More)
In this paper the expression of neural cell adhesion molecule (N-CAM) analyzed by indirect immunofluorescence on human skeletal muscle is reported. In adult human muscle N-CAM is concentrated near neuromuscular junctions and on satellite cells but is nearly undetectable in non synaptic portions of myofibers. N-CAM is abundant on myotubes and intramuscular(More)
PURPOSE Juvenile epithelial corneal dystrophy of Meesmann (MCD, OMIM 122100) is a dominantly inherited disorder characterized by fragility of the anterior corneal epithelium and intraepithelial microcyst formation. Although the disease is generally mild and affected individuals are often asymptomatic, some suffer from recurrent erosions leading to(More)
BACKGROUND AND PURPOSE Mitochondrial cytopathies are heterogeneous disorders affecting multiple systems but most commonly involving the skeletal muscle and central nervous system. The variety of symptoms and signs requires biochemical, morphological and genetic evaluation. The results of genetic studies indicate that there is no direct correlation between(More)
Inclusion body myositis (IBM) seems to be the most common acquired myopathy among patients of age 50 or over. The characteristic clinical features of IBM include involvement of the quadriceps as well as distal muscles, mainly foot extensors and deep finger flexors. The course of the disease is slow but steadily progressive and most patients after 5 to 10(More)
BACKGROUND The main hypotheses regarding mechanisms of transient global amnesia (TGA) are ischemia in hippocampal structures, epileptic genesis, and migraine. In accordance with the hypothesis of a shared, common pathophysiological mechanism in both TGA and migraine, neuromuscular transmission (NMT) abnormalities previously found in migraine were also(More)
Replication of the mitochondrial genome depends on the single DNA polymerase (pol gamma). Mutations in the POLG gene, encoding the catalytic subunit of the human polymerase gamma, have been linked to a wide variety of mitochondrial disorders that show remarkable heterogeneity, with more than 200 sequence variants, often very rare, found in patients. The(More)
BACKGROUND Epilepsy concerns at least 0.5% of population and in most of the cases (approx. 70%) can be treated pharmacologically, which helps to prevent seizures. In all other patients, such a treatment does not produce the desired results. Their condition may require neurosurgical management. The aim of this work was to fuse anatomical MRI images and(More)
