•Quetiapine may cause myoclonus.•Usually, no muscular artifact on the midline EEG electrodes•The EEG pattern of myoclonic jerks is rather polyspike-waves and not only polyspikes.•Failure to recognize muscular artifacts may cause a wrong diagnosis of polyspikes.

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.

Background: Dizziness and unstable gait with resultant falls are common symptoms among the older adults. Most of studies have focused on statistical analysis regarding single factor related to dizziness and unstable gait. On the other hand, there are very few comprehensive studies using a large number of patients except several review papers.

Muscle and tendon injuries are prevalent occurrences during sports activities. Platelet-rich plasma (PRP) is known for its rich content of factors essential for wound healing, inflammation reduction, and tissue repair. Despite its recognized benefits, limited information is available regarding PRP's effectiveness in addressing combined surgical injuries to the gastrocnemius muscle and Achilles tendon.
