Spectrochim Acta A Mol Biomol Spectrosc 2021 Apr 8;258:119790. Epub 2021 Apr 8.

The Institute of Chemical Physics, Key Laboratory of Cluster Science, School of Chemistry and Chemical Engineering, Beijing Institute of Technology, Beijing 100081, PR China.

Tropospheric aerosols are usually complex mixtures of inorganic and organic components, which show non-ideal behavior in hygroscopicity, mass transfer, and partitioning between gas and aerosols. In this study, we applied a novel approach based on a combination of a pulse RH controlling system and a rapid scan vacuum FTIR spectrometer to investigate the mass transfer limit of magnesium sulfate/glutaric acid (GA) mixture aerosol particles. The liquid water band area of the aerosols is used to reveal the mass transfer limit during the rapid pulse RH downward and upward processes. Read More

Successful Management of Refractory Torsades De Pointes Due to Drug-Induced Long QT Syndrome Guided by Point-of-Care Monitoring of Ionized Magnesium.

Cureus 2021 Mar 17;13(3):e13939. Epub 2021 Mar 17.

Department of Anesthesiology, Saitama Medical Center, Saitama Medical University, Kawagoe, JPN.

Ionized magnesium (iMg) is the physiologically active fraction, although total magnesium (tMg) is often used clinically because a dedicated electrode is required to measure the iMg concentration. The tMg concentration is not correlated with the iMg concentration, especially in severely ill patients. In this report, a case of refractory torsades de pointes (TdP) due to drug-induced long QT syndrome was successfully treated with high-dose magnesium sulfate guided by point-of-care monitoring of the iMg concentration.

A Misleading Presentation of Pheochromocytoma in Pregnancy: A Case Report.

Medeni Med J 2021 26;36(1):69-74. Epub 2021 Mar 26.

All India Institute of Medical Sciences, Department of Pathology, Bhubaneswar, India.

Pheochromocytoma is a catecholamine-secreting adrenal tumor and also a rare cause of secondary hypertension in pregnancy. Its low prevalence, nonspecific clinical presentation, and symptoms similar to preeclampsia generate a diagnostic challenge during pregnancy. A 23-year-old hypertensive pregnant woman at 36th gestational week of her first pregnancy was admitted with severe hypertension (210/150 mmHg), headache and proteinuria that made us presume the case as severe preeclampsia.

A bioactive magnesium phosphate cement incorporating chondroitin sulfate for bone regeneration.

Biomed Mater 2021 Apr 16;16(3). Epub 2021 Apr 16.

Department of Orthopedics, Renmin Hospital of Wuhan University, Wuhan 430060, People's Republic of China.

Magnesium phosphate cement (MPC) has been evaluated as an inorganic bone filler due to its favorable biocompatibility, biodegradability, rapid setting, high initial strength, and osteogenic potential. However, the setting time of MPC is so rapid that it makes it difficult to use in practice, and the clinical properties of MPC could be further be improved by adding bioactive materials. Here we developed novel bioactive chondroitin sulfate (CS)-MPC composites (CS-MPCs) by incorporating different amounts of CS into MPC. Read More
