Capsaicin, a polyphenol, is known to regulate energy expenditure and thermogenesis in adipocytes and muscles. However, its role in modulating uncoupling proteins (UCPs) and adenosine triphosphate (ATP)-dependent thermogenesis in muscles remains unclear. This study investigated the mechanisms underlying the role of capsaicin in modulating the UCP- and ATP-dependent thermogenesis in C2C12 myoblasts, as well as the gastrocnemius (GM) and soleus muscles (SM) of mice.

The enzyme creatine kinase (CK) is a biomarker that plays an extremely significant role in the early detection of cardiovascular disorders. Serum levels of CK are regularly monitored in patients with heart attacks, one of the most critical cardiovascular illnesses. In this study, a highly sensitive electrochemical immunosensor system was designed for the importance of early diagnosis of CK.

School of Psychology, University of Nottingham University Park, Nottingham, UK.
Background: Rhythmic median nerve stimulation (MNS) at 10 Hz has been shown to cause a substantial reduction in tic frequency in individuals with Tourette syndrome. The mechanism of action is currently unknown but is hypothesized to involve entrainment of oscillations within the sensorimotor cortex.
Objective: We used functional magnetic resonance spectroscopy (fMRS) to explore the dynamic effects of MNS on neurometabolite concentrations.
Inhibition of Mitochondrial Fission Protein Drp1 Ameliorates Myopathy in the D2-mdx Model of Duchenne Muscular Dystrophy.
bioRxiv
December 2024
Department of Exercise and Health Sciences, University of Massachusetts Boston, Boston, MA.
Although current treatments for Duchenne Muscular Dystrophy (DMD) have proven to be effective in delaying myopathy, there remains a strong need to identify novel targets to develop additional therapies. Mitochondrial dysfunction is an early pathological feature of DMD. A fine balance of mitochondrial dynamics (fission and fusion) is crucial to maintain mitochondrial function and skeletal muscle health.

Nanoscale
January 2025
Department of Chemistry, Federal University of São Paulo (UNIFESP), Diadema, SP, Brazil.
This study aims to use superparamagnetic iron oxide nanoparticles (SPIONs), specifically magnetite (FeO), to deliver deflazacort (DFZ) and ibuprofen (IBU) to Duchenne muscular dystrophy-affected (DMD) mouse muscles using an external magnetic field. The SPIONs are synthesized by the co-precipitation method, and their surfaces are functionalized with L-cysteine to anchor the drugs, considering that the cysteine on the surface of the SPIONs in the solid state dimerizes to form the cystine molecule, creating the FeO-(Cys)-DFZ and FeO-(Cys)-IBU systems for tests. The FeO nanoparticles (NPs) were characterized by Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), dynamic light scattering (DLS), and magnetic measurements.
