Uterotonics are the mainstay of management for postpartum haemorrhage and an understanding of their use is essential for the obstetric anaesthetist. First-line uterotonics comprise oxytocin and carbetocin, which act on the oxytocin receptor, and recent research has shown that lower doses of first-line uterotonics can be used to adequate effect. The oxytocin receptor is known to undergo desensitisation with exposure to the agonist over time and with increasing concentrations.

Naturally occurring vitamin E is a lipophilic plant-derived molecule corresponding to the 2R forms of alpha-tocopherol. A series of natural analogs or tocochromanols are present in nature, including β-, γ- and δ-tocopherol (βT, γT, δT), the corresponding tocotrienols (αTE, βTE, γTE, δTE) and tocomonoenols. Differences between these analogs as lipophilic antioxidants and modulators of molecular processes suggest specific therapeutic properties against various disorders associated with acute and chronic inflammation.

Indole-3-propionic acid (IPA), a metabolite produced by gut microbiota through tryptophan metabolism, has recently been identified as playing a pivotal role in bone metabolism. IPA promotes osteoblast differentiation by upregulating mitochondrial transcription factor A (Tfam), contributing to increased bone density and supporting bone repair. Simultaneously, it inhibits the formation and activity of osteoclasts, reducing bone resorption, possibly through modulation of the nuclear factor-κB (NF-κB) pathway and downregulation of osteoclast-associated factors, thereby maintaining bone structural integrity.

Vladimir Zelman Center for Neurobiology and Brain Rehabilitation, Moscow, Russia.
Introduction: The pursuit of linear dosage in pharmacy is essential for achieving consistent therapeutic release and enhancing patient compliance. This review provides a comprehensive summary of zero-order drug delivery systems, with a particular focus on reservoir-based systems emanated from different microfabrication technologies.
Areas Covered: The consideration of recent advances in drug delivery systems is given to encompass the key areas including the importance of achieving a constant drug release rate for therapeutic applications.
Bergapten Ameliorates Renal Fibrosis by Inhibiting Ferroptosis.

Renal fibrosis is the most common pathway for the development of end-stage renal disease (ESRD) in various kidney diseases. Currently, the treatment options for renal fibrosis are limited. Ferroptosis is iron-mediated lipid peroxidation, triggered mainly by iron deposition and ROS generation.
