Myocardial calcifications: thinking beyond the heart.
Myocardial calcifications are often discovered incidentally and result from dystrophic or metastatic deposition of calcium1. Dystrophic calcification represents the sequalae of local tissue damage with necrosis, most commonly from myocardial ischemia. Unlike the prior, metastatic calcification is the result of abnormal calcium homeostasis; including renal failure, hyperparathyroidism, and vitamin D deficiency. Myocardial calcifications are not entirely a benign finding, since they can lead to heart failure, arrhythmias and sudden cardiac death2. (Source: The American Journal of Medicine)

An overview of statin-induced myopathy and perspectives for the future.
Authors: Nikolic D, Banach M, Chianetta R, Luzzu LM, Pantea Stoian A, Diaconu CC, Citarrella R, Montalto G, Rizzo M Abstract Introduction: Statins remain the most commonly prescribed lipid-lowering drug class for the treatment of atherosclerotic cardiovascular disease. Their well-recognized side effects are known as statin-associated muscle symptom (SAMS). Some advances in this field have been made in recent years, but the understanding of the mechanisms has lagged. Investigating the specific role of the anti-HMGCR autoantibody, pharmacokinetic genetic variants, characterization of the known phenotypes of statin to...

Thiamine pyrophosphate diminishes nitric oxide synthesis in endothelial cells.
Authors: Alcázar-Leyva S, Zapata E, Bernal-Alcántara D, Gorocica P, Alvarado-Vásquez N Abstract Although thiamine pyrophosphate (TPP) is considered a protective agent for endothelial cells, it is still unknown if this is associated with nitric oxide (NO) synthesis. Our aim was to evaluate the synthesis of NO in endothelial cells incubated with TPP and high glucose concentrations. Endothelial cells from the umbilical cord vein from newborns (n = 20), were incubated with 5, 15 or 30 mmol/L glucose, in absence or presence of 0.625 mg/ml of TPP.

Inhibition of lipid peroxidation during the reproductive period extends the lifespan of Caenorhabditis elegans.
Authors: Sakamoto T, Maebayashi K, Tsunoda Y, Imai H Abstract Glutathione peroxidase 4 (GPx4) is a unique antioxidant enzyme that directly reduces the phospholipid hydroperoxides (PLOOH) generated in biomembranes using glutathione as the reductant. We have previously reported that the Caenorhabditis elegans gpx-quad mutant, which lacks all homologous genes of GPx4 has a reduced lifespan compared with the wild-type. However, the mechanisms underlying the lifespan reduction remain unclear. By monitoring the change in PLOOH production with age, we found that PLOOH was elevated in the gpx-quad mutants compared with the...

AbstractElectronic cigarettes are a novel and emerging product increasingly used by the general public. However, despite their popularity, they remain poorly studied and with likely serious health risks. EVALI, or “electronic cigarette or vaping product use–associated lung injury,” is a recently described entity at the forefront of current investigations. Though EVALI has been linked to vitamin E acetate, a constituent of THC vaping products, electronic cigarettes likely pose a host of other pulmonary t oxicities.

Association of Vitamin D With Periodontal Disease: A Narrative Review
Conclusions: There is conflicting evidence regarding the effects of 25(OH)D on periodontal disease severity, progression and tooth loss, with some studies reporting beneficial effects of higher 25(OH)D serum concentrations on periodontal health and tooth retention, whereas others could not find such an association. Limited evidence also supports a positive association between 1,25(OH)2D3 and periodontal health as well as a trend towards better periodontal health with vitamin D supplementation. Finally, various vitamin D polymorphisms were associated with chronic and aggressive periodontitis, with different outcomes reporte...

Vitamin C and Its Role in Periodontal Diseases – The Past and the Present: A Narrative Review
Van der Velden, UbelePage 115 - 124In humans, ascorbic acid, better known as vitamin C, is a true vitamin because humans lack the ability to synthesise it. Vitamin C exhibits a number of enzymatic and non-enzymatic effects but all are accounted for by the ability of vitamin C to donate electrons and therefore acts as a reducing agent. It has a wide range of functions. For example, it acts as co-factor for a number of enzymes including those involved in collagen hydroxylation, prevents oxidative damage to DNA and intracellular proteins, and in plasma it increases endothelium-dependent vasodilatation, and reduces extracellul...

α1-Microglobulin Binds Illuminated Flavins and Has a Protective Effect Against Sublethal Riboflavin-Induced Damage in Retinal Epithelial Cells
Riboflavin (vitamin B2) is an important constituent of the prosthetic groups flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), which are utilized as electron-carriers in energy metabolism. Excitation by UV-light leads to the generation of riboflavin radicals and reactive oxygen species (ROS), which can oxidize a wide range of biomolecules. The human protein α1-microglobulin (A1M) is a reductase and a radical scavenger, which can protect cells and matrix against oxidative damage. Here, we provide evidence of a molecular interaction between illuminated riboflavin and A1M, similar to the radical scaveng...

Endothelial injury, F-actin and vitamin-D binding protein after hematopoietic stem cell transplant and association with clinical outcomes.
Abstract Endothelial injury after hematopoietic stem cell transplant is an important initiating factor for early transplant toxicities of thrombotic microangiopathy and acute graft versus host disease. We hypothesized that release of the angiopathic molecule filamentous actin from hematopoietic cells lysed during conditioning prior to stem cell transplant would be associated with clinical outcomes. We detected filamentous actin in the blood of 52% of stem cell transplant recipients in the first 14 days after transplant, and children with detectable filamentous actin had significantly elevated risk of thrombotic mi...

[Research Articles] Control of brain tumor growth by reactivating myeloid cells with niacin
Glioblastomas are generally incurable partly because monocytes, macrophages, and microglia in afflicted patients do not function in an antitumor capacity. Medications that reactivate these macrophages/microglia, as well as circulating monocytes that become macrophages, could thus be useful to treat glioblastoma. We have discovered that niacin (vitamin B3) is a potential stimulator of these inefficient myeloid cells. Niacin-exposed monocytes attenuated the growth of brain tumor–initiating cells (BTICs) derived from glioblastoma patients by producing anti-proliferative interferon-α14. Niacin treatment of mice bea...
