The use of calcium sulfate beads (CSBs) as a carrier for local delivery of antibiotics is increasingly reported for the treatment of localized infections. They are used most commonly in bone and joint infections, post-trauma infections, diabetes-related foot wounds, and vascular grafts. Hypercalcemia is rarely reported with CSB use but is an important safety concern, and patients at higher risk should be identified prospectively and followed carefully postoperatively. This case report details an 85-year-old male who developed severe, symptomatic postoperative hypercalcemia after antibiotic bead placement in the right knee. He presented with confusion, weakness, and lethargy, and was subsequently treated with fluids, calcitonin, and alendronate. The patient quickly returned to normal mental status, and calcium levels normalized, leading to discharge. The case report and review of the literature describe an incident of severe hypercalcemia attributed to the use of antibiotic-eluting CSBs and describe the risk factors and time course that may be expected.

Ventricular arrhythmias (VAs) are major causes of sudden cardiac death in chronic kidney disease (CKD) patients. Indoxyl sulfate (IS) is one common uremic toxin found in CKD patients. This study investigated whether IS could induce VAs via increasing right ventricular outflow tract (RVOT) arrhythmogenesis.

Exposure to alcohol can induce different degrees of damage to various tissues and organs, and brain is the most vulnerable part affected by alcohol. However, there is no detailed report on whether intermittent alcohol exposure can result in pathological changes in the hypothalamus of adolescent rats and the detailed mechanism. This study investigated pathological changes in the hypothalamus, probed the levels of inflammatory factors, and detected the expression of proteins related to endoplasmic reticulum stress (ERS) to determine whether ERS is involved in the injury process of the hypothalamus and the protective mechanism of L-3-n-butylphthalide (L-NBP).

In the process of zinc hydrometallurgy, the content of fluorine in zinc sulfate solution directly affects the stripping of the zinc plate, which easily leads to the deterioration of working conditions. It not only has a serious impact on the entire zinc hydrometallurgical system but also causes huge economic losses. Especially in the process of zinc secondary resource utilization, the concentration of fluoride ions in the electrolyte exceeds the control standard of smelting enterprises, which has become a long-term technical challenge in the smelting industry.

This study examined the effects of salt content and salt type on the properties of the hydroxypropyl guar gum fracturing fluid. In this study, we conducted a thorough analysis of the impact that various ions in seawater have on the performance of fracturing fluids. We identified the cross-linked polymer that performs optimally at a specific concentration of the binding agent.

The reactions at the mineral-solution interface govern whether heavy metals (HMs) ions are retained within minerals or migrate with the solution, thus influencing their cycling and fate. However, the mechanisms driving this differential behavior of HMs at the interface remain poorly understood. In this study, we present a novel paradigm for the selective retention of HMs ions at the mineral-solution interface.
