Special Issue Information

Dear Colleagues,

In recent years, interest in skeletal muscle disorders has significantly increased, primarily motivated by the arrival of new investigative techniques and therapeutic perspectives.

The metabolic myopathies related to skeletal muscle are a heterogeneous group of rare, genetically determined conditions characterised by defects in the biochemical pathways of storage, mobilisation and utilisation of the substrates useful for energy generation and the contraction of muscle cells. They can develop at any age and have varying clinical presentations.

New and improved diagnostic tools are becoming increasingly available for some of these disorders, and targeted therapies for specific biochemical deficits have been developed.

The aims of this Special Issue are to a) explore the developments in our understanding and treatment of these conditions; b) highlight new treatments available for skeletal muscle disorders, e.g., Pompe’s disease. We welcome original research and brief case reports that focus on pathogenetic mechanisms; clinical features; and recent advances in the investigation and treatment of the principal metabolic muscle diseases, such as glycogen storage disorders (GSD), fatty acid oxidation disorders, disorders of purine metabolism and mitochondrial disorders. Research using cellular or animal models is also welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metabolites is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is a maternally inherited genetic mitochondrial disease with a typical onset in the first two decades of life and a major involvement of central nervous system (CNS). We present the case of a man affected with an oligosymptomatic, genetically determined MELAS syndrome, whose clinical picture dramatically and irreversibly worsened following a mild head injury. We hypothesize that the CNS metabolic stress induced by the brain injury activated an irreversible cascade of events leading to progressive neurodegeneration because damaged mitochondria were unable to restore the balance between energy requirements and availability.
