Background: Hypomagnesemia was identified as a strong risk factor for cardiovascular disease in patients with chronic renal failure (CRF). However, the effects of magnesium (Mg) on vascular calcification (VC) have not been fully elucidated. Thus, we aim to determine the effects of Mg citrate (MgCit) on VC in CRF rats.
Methods: Rats were divided into 5 groups: group 1 (normal diet), group 2 (normal diet with MgCit), group 3 (the VC model of CRF induced by 0.75% adenine and 0.9% phosphorus diet from day 1 to day 28), group 4 (group 3 treated with low-dose MgCit from day 1 to day 42), and group 5 (same as group 3 except the high-dose MgCit). All rats were killed at day 43 with collection of blood and aortas. Then, serum biochemical parameters, VC-related staining, calcium and P contents, alkaline phosphatase contents and activity, expression of alpha smooth muscle actin, and runt-related transcription factor 2 (RUNX2) in aortas were assessed.
Results: Group 3 had extensive VC. The VC degree decreased in groups 4 and 5 in a dose-depended manner with reduced calcium content, P levels, alkaline phosphatase content and activity, and protein levels of RUNX2 and increased protein levels of alpha smooth muscle actin in aortas.
Conclusions: MgCit exerted a protective role in VC in adenine-induced CRF rats; thus, it may be a potential drug for the prevention of VC in patients with CRF.

: The association between nuts and seeds (nuts/seeds) consumption and abdominal aortic calcification (AAC) has been studied rarely, if at all. However, AAC is a good marker of CVD risk and premature mortality. Consequently, the present observational study was conducted.

Late-onset Alzheimer's disease (LOAD) is a chronic, multifactorial, and progressive neurodegenerative disease that associates with aging and is highly prevalent in our older population (≥65 years of age). This hypothesis generating this narrative review will examine the important role for the use of sodium thiosulfate (STS) as a possible multi-targeting treatment option for LOAD. Sulfur is widely available in our environment and is responsible for forming organosulfur compounds that are known to be associated with a wide range of biological activities in the brain.

Calcium deposition in vascular smooth muscle cells (VSMCs), a form of ectopic ossification in blood vessels, can result in rigidity of the vasculature and an increase in cardiac events. Here, we report that CCAAT/enhancer-binding protein beta (C/EBPβ) potentiates calcium deposition in VSMCs and mouse aorta induced by inorganic phosphate (Pi) or vitamin D. Based on cDNA microarray and RNA sequencing data of Pi-treated rat VSMCs, C/EBPβ was found to be upregulated and thus selected for further evaluation.

Background: Vascular calcification (VC) is a dynamic, tightly regulated process driven by cellular activity and resembling the mechanisms of bone formation, with specific molecules playing pivotal roles in its progression. We aimed to investigate the involvement of the bone morphogenic proteins (, , , and ) system in this process. Our study used an advanced in vitro model that simulates the biological environment of the vascular wall, assessing the ability of a phosphate mixture to induce the osteoblastic switch in human coronary artery smooth muscle cells (HCASMCs).

Osteoporosis and cardiovascular disease (CVD) share common risk factors and pathophysiological mechanisms, raising concerns about the cardiovascular implications of sclerostin inhibition. Romosozumab, a monoclonal antibody that targets sclerostin, is effective in increasing bone mineral density (BMD) and reducing fracture risk. However, evidence suggests that sclerostin inhibition may adversely affect vascular calcification, potentially increasing the risk of myocardial infarction (MI) and stroke.
