Description of four new species of marine macroalgae from Rangitāhua, New Zealand

open access: yesPhycological Research, EarlyView.
ABSTRACT Four species of marine macroalgae are described from Rangitāhua, the northern islands of the New Zealand archipelago. The flora of this region has been considered to have its strongest affinities with other warm‐water regions of the Pacific and Indian Oceans, with very low levels of endemism.

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Alternative Lead ECG Placements

open access: yesAnnals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
Alternative ECG lead placements can improve diagnostic yield when the standard 12‐lead ECG is suboptimal or infeasible. This review summarizes practical, scenario‐driven modifications (right‐sided, posterior, seated/prone, Lewis, Fontaine, torso‐based, and monitoring configurations) to better detect ischemia, right ventricular disease/ARVD, and ...

Two strikes: A case study of consecutive ST-elevation myocardial infarctions (STEMI) in two different coronary arteries

open access: yesEuropean Journal of Case Reports in Internal Medicine
An acute ST-elevation myocardial infarction (STEMI) followed by reinfarction within a short period of time is typically due to stent thrombosis. However, a STEMI caused by occlusion of one vessel followed by a repeat infarction due to occlusion of a ...

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 16, April 20, 2026.
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

A Meta‐Analysis and Simplified Nomenclature for Diagonal Coronary Artery and Ramus Intermedius Across Adult and Pediatric Hearts

open access: yesClinical Anatomy, Volume 39, Issue 3, Page 305-324, April 2026.
ABSTRACT Anatomical descriptions of left‐sided oblique coronary branches remain inconsistent, hindering imaging interpretation and surgical planning. To quantify the prevalence, branching patterns and morphometry of the ramus intermedius (RI) and diagonal branches, and propose a unified nomenclature.

ST‐Segment Elevation Following Adenosine Administration for SVT: Diagnostic Challenge in Acute Cardiac Care

open access: yesClinical Case Reports, Volume 14, Issue 4, April 2026.
ST segment elevation following adenosine administration in the inferior leads (II, III, aVF). ABSTRACT Adenosine, used to treat paroxysmal supraventricular tachycardia, commonly causes flushing, sweating, palpitations, and hypotension. Rarely, it may induce ST‐segment elevation with chest pain, suggesting transient myocardial ischemia or coronary ...
