Muscle fiber types switched during the development of experimental autoimmune myasthenia gravis via the PI3K/Akt signaling pathway.

As one of the largest organs of our human body, skeletal muscle has good research prospects in myasthenia gravis (MG), the symptoms of which include systemic skeletal muscle weakness. Skeletal muscle is composed of two types of muscle fibers. Different fiber subtypes can be converted into each other; however, the underlying mechanism is not yet clear.

Functional abnormalities of the glymphatic system in cognitive disorders.

Various pathological mechanisms represent distinct therapeutic targets for cognitive disorders, but a balance between clearance and production is essential for maintaining the stability of the brain's internal environment. Thus, the glymphatic system may represent a common pathway by which to address cognitive disorders. Using the established model of the glymphatic system as our foundation, this review disentangles and analyzes the components of its clearance mechanism, including the initial inflow of cerebrospinal fluid, the mixing of cerebrospinal fluid with interstitial fluid, and the outflow of the mixed fluid and the clearance.

Cardiotoxicity of polystyrene nanoplastics and associated mechanism of myocardial cell injury in mice.

Aims: Nanoplastics (NPs) are emerging organic pollutants generated by plastic degradation and are ubiquitous in the environment. They can be accumulated through the food webs and enter the human body through dietary intake, posing health risks. The main target organs of NP accumulation are the lungs, liver, heart, and kidneys.

Early Evaluation of the Interaction and Gender Differences in Combination of Apatinib and Metoprolol Using Humanized CYP2D6 Model.

Apatinib, a commonly used tyrosine kinase inhibitor in cancer treatment, can cause adverse reactions such as hypertension. Hypertension, in turn, can increase the risk of certain cancers. The coexistence of these diseases makes the use of combination drugs more common in clinical practice, but the potential interactions and regulatory mechanisms in these drug combinations are poorly understood.
