Myotonic Dystrophy type 1 (DM1) is an inherited disease characterized by multi-systemic symptoms, particularly in skeletal muscles (progressive weakness and atrophy, myotonia). The inventors screened 7 500 bioactive compounds for their ability to improve the myogenic fusion and reduce the molecular hallmarks of DM1 skeletal muscle cells. The inventors found that five compounds, all inhibiting HDAC6, a cytoplasmic histone deacetylase, were effective at the micromolar range in normalizing the myogenic fusion, reducing the number of nuclear foci of mutant DMPK mRNA, decreasing the expression level of DMPK mRNA, restoring the splicing of several genes, and increasing the acetylation of SMAD3, a transcription factor involved in muscle development. The effects of HDAC6 inhibitors were observed both in immortalized and hiPSC-derived skeletal muscle cells from DM1 patients, and in different stages of differentiation. Thus, the present invention relates to the use of selective HDAC6 inhibitors for the treatment of DM1.

In MRI examinations of patients with acute ischemic stroke, it is often difficult for patients to fix and hold their heads due to impaired consciousness or limb weakness. Therefore, this invention provides a tool that is structurally rational, easy to operate, and effectively enhances the head fixation effect. [Solution] A tool to support MRI examination, comprising a base 1, a head rest member 2 with adjustable anterior-posterior position, a lateral limiting member 3 with an elastic buffer layer, and an adjustment mechanism 4. The head rest member slides relative to the base to adapt to the length of the patient's neck.
