Iron and Other Metal Ions in Human Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
Iron, copper, zinc, and calcium orchestrate cellular function through distinct yet cooperative mechanisms: redox‐active iron and copper cycle between oxidation states to act as Fenton catalysts and electron carriers in oxidative phosphorylation (OXPHOS); redox‐inert zinc serves as a structural component of zinc‐finger proteins and a catalytic cofactor ...

Supradiaphragmatic origin of the celiac trunk leading to median arcuate ligament syndrome with superior mesenteric artery involvement

Journal of Vascular Surgery Cases and Innovative Techniques
Median arcuate ligament (MAL) syndrome (MALS) is a rare condition caused by compression of the celiac artery by the MAL. Symptoms include abdominal pain, nausea, and weight loss.

Multifrequency Magnetic Resonance Elastography of the Abdominal Aortic Wall: Segmental, Positional and Flow Effects

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
In vivo abdominal aortic wall–specific MRE enables reproducible wall stiffness mapping while minimizing the intraluminal signal interference, revealing segment‐ and posture‐dependent stiffness patterns that complement morphology and flow measures for clinical evaluation of abdominal aortic wall health.

Celiac axis stenosis due to median arcuate ligament compression in a patient who underwent pancreatoduodenectomy; intraoperative assessment of hepatic arterial flow using Doppler ultrasonography: a case report

Journal of Medical Case Reports, 2018
Background Celiac axis stenosis due to compression by the median arcuate ligament has been reported in patients undergoing pancreaticoduodenectomy; it leads to the development of major collateral pathways that feed the hepatic artery.

Exercise and Autonomic Cardiovascular Function—Insights From Spinal Cord‐Injured Humans: A Narrative Review

Acta Physiologica, Volume 242, Issue 10, October 2026.
ABSTRACT The cardiovascular response to acute exercise is mediated by the autonomic nervous system (ANS) control mechanisms that modulate vascular resistance to support blood pressure and ensure adequate blood flow to active muscles. These autonomic neurocirculatory control mechanisms include a feedforward mechanism, known as central command, and three

Intestinal Malrotation With Chronic Midgut Volvulus, Chylous Ascites, and Severe Malnutrition in an Adolescent: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT In adolescents, chronic midgut volvulus can present insidiously over years with postprandial pain and progressive malnutrition, occasionally with chylous ascites from sustained mesenteric lymphatic obstruction. Prompt surgical correction can produce marked nutritional recovery, supporting secondary rather than primary lymphatic obstruction as ...
