Hamman's crunch—A pathognomonic sign of pneumomediastinum

Equine Veterinary Education, Volume 38, Issue 9, Page e571-e576, September 2026.
Summary Pneumomediastinum, particularly spontaneous pneumomediastinum, is uncommon and presents a diagnostic challenge. In human medicine, auscultation of Hamman's crunch, a crepitant, crunching noise, audible over the cardiac region in synchrony with the heartbeat, is considered pathognomonic for pneumomediastinum.

Pulsed Electric Field Processing Enhances the Endothelial Bioefficacy of Red Beet (Beta vulgaris L.) Extracts by Restoring Endothelial Nitric Oxide Synthase–Nitric Oxide Signaling in High‐Fat Diet Rats

eFood, Volume 7, Issue 4, August 2026.
Pulsed electric field (PEF) processing qualitatively reshapes the phytochemical profile of red beet extracts, resulting in enhanced endothelial bioefficacy. Compared with conventional extraction, PEF‐treated extracts more effectively restore nitric oxide signaling, suppress endothelial inflammation, and normalize vascular structure in high‐fat diet ...

Endothelial AGGF1 Deficiency Causes Mitochondrial Dysfunction and Contributes to Age‐Elevated Blood Pressure

Aging Cell, Volume 25, Issue 8, August 2026.
Endothelial AGGF1 deficiency contributes to early vascular aging and age‐elevated blood pressure via inhibiting the SESN2/p‐eNOS pathway. Age‐dependent AGGF1 attenuation reduces its binding to the SESN2 promoter. SESN2 downregulation induces mitochondrial respiratory dysfunction and elevated mitochondrial ROS, thereby reducing eNOS phosphorylation ...

Comparison of hemodynamic response and vasopressor requirement following spinal anaesthesia between normotensive and severe preeclamptic women undergoing caesarean section: A prospective study

Journal of Obstetric Anaesthesia and Critical Care, 2013
Background: Spinal anesthesia is the technique of choice in cesarean sections, but it is not widely accepted in severe pre-eclampsia due to fear of sudden and extensive sympathetic blockade. The aim of the present study was to compare the heart rate (HR),

Gβγ subunit activation of KV7 and BKCa channels underlies calcitonin gene‐related peptide vasorelaxation in myogenic rat coronary resistance arteries

British Journal of Pharmacology, Volume 183, Issue 16, Page 5018-5032, August 2026.
Abstract Background and Purpose CGRP is a potent, clinically relevant coronary vasodilator known to play a role in cardioprotection. Here, we investigated the precise intracellular signalling pathways leading to vasodilation in small coronary arteries.
