This review explores the therapeutic potential of the stable gastric pentadecapeptide BPC 157 in addressing electrolyte imbalances, specifically hyperkalemia, hypokalemia, hypermagnesemia, and hyperlithemia. In hyperkalemia, BPC 157 demonstrated a comprehensive counteractive effect against KCl overdose (intraperitoneally, intragastrically, and in vitro), effectively mitigating symptoms such as muscular weakness, hypertension, sphincter dysfunction, arrhythmias, and lethality. It also counteracted the adverse effects of succinylcholine and magnesium overdose, including systemic muscle paralysis, arrhythmias, and hyperkalemia.

The purpose of this study is to solve the problem of ammonia (NH) release when modified magnesium slag (MMS) is used as coal mine backfill cementitious material, and to explore its chemical mechanism and put forward effective solutions. Uniaxial compressive strengths (UCS) hydration kinetics, scanning electron microscope (SEM), and thermogravimetric analysis-derivative thermogravimetry (TG-DTG), X-ray diffractometer (XRD) and other testing methods were used to study the evolution of the properties of MMS-based backfill material, which provided a scientific basis for the safe utilization of MMS. First, the chemical mechanism underlying the release of NH from MMS was identified, and it was confirmed that MgN and LiN are the main nitrogen sources.

In situ bone regeneration and vertical bone augmentation have been huge problems in clinical practice, always imposing a significant economic burden and causing patient suffering. Herein, MgZnYNd magnesium alloy rod implantation in mouse femur resulted in substantial subperiosteal new bone formation, with osteoimmunomodulation playing a pivotal role. Abundant macrophages were attracted to the subperiosteal new bone region and proved to be the most important regulation cells for bone regeneration.
