Magnesium sulfate is widely used as a food additive and as an orally administered medication. The aim of this study was to evaluate the possible cytotoxicity of magnesium sulfate on AGS human gastric adenocarcinoma cells and gastric mucosa in mice. A trypan blue exclusion assay was used to determine the reduction in viability of AGS cells exposed to magnesium sulfate, and then effects on cell proliferation were quantified. The role of magnesium sulfate-mediated pro-inflammatory cytokine production in AGS cells was also investigated. mRNA expression for IL-1β, IL-6, IL-8, and TNF-α was determined by RT-PCR, and secretion of these cytokines was measured by ELISA. Immunohistochemical evaluation of IL-1β, IL-6, and TNF-α expression was conducted in mouse gastric mucosa. Addition of 3 to 50 mM magnesium sulfate to AGS cells inhibited both cell proliferation and cell viability in a dose-dependent manner. Magnesium sulfate had little effect on production of IL-1β or IL-6 but significantly inhibited production of IL-8. The animal model demonstrated that magnesium sulfate induced production of IL-1β, IL-6, and TNF-α. These preliminary data suggest that magnesium sulfate had a direct effect on the stomach and initiates cytotoxicity in moderate concentrations and time periods by inhibiting viability and proliferation of AGS cells and by regulating expression and/or release of pro-inflammatory cytokines.

Aim: To assess the effectiveness of intravenous caffeine citrate in paediatric asthma exacerbation unresponsive to beta2-agonists and steroids.
Methods: A 10-year retrospective cohort study was conducted on asthmatic children unresponsive to beta2-agonists and steroids, who were treated with either intravenous caffeine citrate or magnesium sulphate. The study outcomes were changes in the Paediatric Respiratory Assessment Measure (PRAM) score, duration of oxygen therapy and paediatric intensive care unit (PICU) length-of-stay.

Preterm birth (PTB) remains a leading cause of neonatal morbidity and mortality, with inflammation-induced PTB posing a significant challenge due to its complex pathophysiology. To address this, we developed an in vitro platform utilizing hTERT-immortalized human myometrial (hTERT-HM) cells integrated with a multielectrode array (MEA) biosensing system and optical calcium imaging. Compared to primary uterine myometrial cells, hTERT-HM cells exhibit superior reproducibility, high scalability, and convenient manipulation, facilitating the consistent and large-scale investigations.

Background: Preeclampsia is a major hypertensive disorder of pregnancy, which may lead to severe complications, particularly in the first two weeks of the postpartum period. During the postpartum period, blood pressure levels remain high, often increasing to levels higher than those experienced during pregnancy. Furosemide, a fast-acting diuretic, reduces the intravascular volume overload and may represent an alternative to accelerate the normalization of blood pressure levels.

Although intraoperative magnesium sulphate administration has various advantages, its influence on the occurrence of postoperative acute kidney injury (AKI) remains unclear, particularly in patients undergoing robot-assisted radical prostatectomy (RARP). The steep Trendelenburg position and a high intra-abdominal pressure can render patients susceptible to AKI after surgery. This study aimed to evaluate the effects of intraoperative magnesium sulphate administration on postoperative AKI in patients who underwent RARP.
