Many bacteria swim in liquid or swarm on surface using the flagellum rotated by a motor driven by specific ion flow. The motor consists of the rotor and stator, and the stator converts the energy of ion flow to mechanical rotation. However, the ion pathway and the mechanism of stator rotation coupled with specific ion flow are still obscure.

Anemia is a potentially life-threatening blood disorder caused by an insufficient erythroblast volume in the circulatory system. Self-renewal failure of erythroblast progenitors is one of the key pathological factors leading to erythroblast deficiency. However, there are currently no effective drugs that selectively target this process.

This study aimed to compare the inhibitory effect of flunixin meglumine and meloxicam on the smooth muscles of the gastrointestinal tract in male cattle. Tissue samples, including the abomasum, ileum, proximal loop and centripetal gyri of the ascending colon, were collected from routinely slaughtered male cattle. These samples were sectioned into strips and mounted in an isolated tissue bath system.

DNA methylation is a crucial epigenetic modification used as a biomarker for early cancer progression. However, existing methods for DNA methylation analysis are complex, time-consuming, and prone to DNA degradation. This work demonstrates selective capture of unmethylated DNAs using ZnO nanowires without chemical or biological modifications, thereby concentrating methylated DNA, particularly those with high methylation levels that can predict cancer risk.

Background: Therapeutic drug monitoring-informed teicoplanin dosage adjustments are recommended for safe and effective use. The authors' group previously reported that only half of children reached the recommended blood concentration range at the standard teicoplanin loading dose. It has been suggested that higher loading doses are necessary; however, the usefulness and safety of high-dose loading in pediatric patients in clinical practice are unknown.
