Myopericarditis, a rare inflammatory condition affecting the heart and its surrounding layers, can lead to serious consequences if not promptly diagnosed and treated. A recent case involved a 28-year-old man with no significant medical history who developed severe chest pain and was diagnosed with myopericarditis induced by the Epstein-Barr virus (EBV). The patient's symptoms, imaging, and lab test results suggest myopericarditis.

Acute transverse myelitis (ATM) is a syndrome of multiple etiologies, with acute or subacute onset in which inflammation of the spinal cord results in neurological deficits, including weakness, sensory loss, and autonomic dysfunction. It is often associated with infectious or autoimmune etiologies but can be considered idiopathic when extensive workup is negative. We present a case of a young African American female who presented with acute onset of bilateral lower extremity weakness, loss of sensation, and autonomic dysfunction.

: Inositol 1,4,5-trisphosphate receptors (IP3Rs) are intracellular calcium (Ca) release channels located on the endoplasmic/sarcoplasmic reticulum. The availability of the structure of the ligand-binding domain of IP3Rs has enabled the design of compatible ligands, but the limiting step remains their actual effectiveness in a biological context.: This article summarizes the compelling literature on both agonists and antagonists targeting IP3Rs, emphasizing their strengths and limitations.

The potential beneficial effects of the antioxidant properties of vitamin C have been investigated in a number of pathological conditions. In this review, we assess both clinical and preclinical studies evaluating the role of vitamin C in cardiac and vascular disorders, including coronary heart disease, heart failure, hypertension, and cerebrovascular diseases. Pitfalls and controversies in investigations on vitamin C and cardiovascular disorders are also discussed.
