Preterm birth remains a leading cause of neurodevelopmental disability in offspring, prompting various preventive measures. However, controversies persist surrounding these approaches, particularly regarding beta-mimetic drugs. In Japan, it remains a concerning reality that ritodrine infusion continues to be used for long-term tocolysis in preterm labor, despite the warning issued by the US Food and Drug Administration.

Microneedle(MN)-based drug delivery is one of the potential approaches to overcome the limitations of oral and hypodermic needle delivery. An in silico model has been developed for hollow microneedle (HMN)-based drug delivery in the skin and its subsequent absorption in the blood and tissue compartments in the presence of interstitial flow. The drug's reversible specific saturable binding to its receptors and the kinetics of reversible absorption across the blood and tissue compartments have been taken into account.

Positive inotropic responses upon administration of milrinone, an inhibitor of the phosphodiesterase enzyme (PDE), involve a well-pronounced positive chronotropic effect. Here we tested whether milrinone evokes this chronotropic response solely by PDE inhibition or by a concerted action that involve additional pharmacological targets. Milrinone stimulated increases in heart rate were studied in right atrial preparations of guinea pig in the presence or absence of inhibitors of putative ancillary molecular pathways or ion channels: i.

Backgroud: Biomimetic nanoplatforms based on membrane coating strategies have received increasing attention in the field of medical research. However, it cannot perform biomedical imaging screening, which is essential for real-time identification. As a rich source of new drug discovery, traditional Chinese medicine (TCM) has made important contributions to the treatment of many diseases.
