Background: Pharmacological vitamin C (Vit-C), or high-dose Vit-C has recently gained attention as a potential cancer therapeutic. However, the anticancer activity of Vit-C has not been investigated in realistic 3D models of human cancers, especially with respect to breast cancer (BC), and its potential benefits remain under debate. Herein, we investigate the activity and mechanism of action of pharmacological Vit-C on two BC tumor spheroids.

Chemodynamic therapy (CDT) is a promising and potent therapeutic strategy for the treatment of cancer. We developed a DNA origami-based enzymatic cascade nanoreactor (DOECN) containing spatially well-organized Au nanoparticles and ferric oxide (FeO) nanoclusters for targeted delivery and inhibition of tumor cell growth. The DOECN can synergistically promote the generation of hydrogen peroxide (HO), consumption of glutathione, and creation of an acidic environment, thereby amplifying the Fenton-type reaction and producing abundant reactive oxygen species, such as hydroxyl radicals (•OH), for augmenting the CDT outcome.

Oxidative stress (OS) is a common feature of many inflammatory diseases, oral pathologies, and aging processes. The impact of OS on periodontal ligament cells (PDLCs) in relation to oral pathologies, including periodontal diseases, has been investigated in different studies. However, its impact on orthodontic tooth movement (OTM) remains poorly understood.

Hematological emergencies are critical medical conditions that require immediate attention due to their rapid progression and life-threatening nature. As various examples, hypercalcemia, often associated with cancers such as multiple myeloma, can lead to severe neurological and cardiac dysfunction. Hyperleukocytosis, common in acute myeloid leukemias, increases the risk of leukostasis and multiorgan failure.

, a common cause of gastroenteritis worldwide, has also been associated with rare extraintestinal infections, including myocarditis. We report a unique case of a 24-year-old male who presented with febrile diarrhea and acute chest pain. Diagnostic investigations revealed elevated cardiac troponin levels, normal electrocardiography findings, and myocardial inflammation on cardiac magnetic resonance imaging, confirming the diagnosis of acute myocarditis.
