Perfusion Fixation With Glutaraldehyde and Post-Fixation With Osmium Tetroxide for Electron Microscopy [PDF]

open access: yes, 1968
The conductivity of cerebral cortex drops during perfusion with glutaraldehyde in 5 min to about 60% of the original value, to remain unchanged during the subsequent 10-15 min of perfusion.

A re‐usable 3D‐printed training model for the endodontic management of dental trauma in immature teeth

open access: yesInternational Endodontic Journal, Volume 59, Issue 6, Page 1188-1199, June 2026.
Abstract Aim To develop a 3D‐printed model enabling treatment simulation of trauma‐related endodontic and restorative procedures like revitalization or placement of an apical plug on teeth with incomplete root formation. Methodology To generate a realistic training model suitable for trauma‐related simulations, CT‐Data sets were segmented, combined ...

Malignant Arrhythmia in Apical Ballooning Syndrome: Risk Factors and Outcomes

open access: yesIndian Pacing and Electrophysiology Journal, 2008
Objectives: We sought to determine the frequency and outcomes with symptomatic arrhythmia in patients with apical ballooning syndrome (ABS). Methods: A retrospective review of the Mayo Clinic Angiography database was conducted to identify patients who ...

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3001-3013, June 2026.
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

Pharmacological inhibition of hydroxysteroid 11‐beta dehydrogenase type 1 (11‐βHSD1) after myocardial infarction preserves cardiac function in a translational mini‐pig model

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 10, Page 2236-2255, May 2026.
Abstract Background and Purpose Plasma glucocorticoids increase acutely after MI, thereafter tissue levels are amplified selectively within cells expressing 11‐ßhydroxysteroid dehydrogenase type 1 (11‐ßHSD1) that regenerates active glucocorticoids from circulating metabolites.

Cholangiolocellular Component Predicts a Biologically Distinct Subgroup of Mass‐Forming Intrahepatic Cholangiocarcinoma

open access: yesCancer Science, Volume 117, Issue 5, Page 1510-1523, May 2026.
We identified two distinct molecular subgroups of mass‐forming intrahepatic cholangiocarcinoma (MF‐iCCA) based on the presence of a histological cholangiolocellular carcinoma (CLC) component. The CLC‐related molecular subgroup showed better prognosis and highly angiogenic features, as confirmed by both genetic analysis and morphological observation ...

Where We're Going, We Won't Need Eyes to See: Distributional Range Size Drivers of European Subterranean Spiders

open access: yesJournal of Biogeography, Volume 53, Issue 5, May 2026.
ABSTRACT Aim Understanding why closely related species can have drastically different distributional range sizes is a fundamental question in biology. However, answering this question is challenging due to the multiple inter‐related factors that shape species distributions, particularly in continental regions, where unclear ecological and geographic ...

A fully echo-guided trans-apical aortic valve implantation [PDF]

open access: yes, 2017
The trans-apical aortic valve implantation (TA-AVI) is an established technique for high-risk patients requiring aortic valve replacement. Traditionally, preoperative (computed tomography (CT) scan, coronary angiogram) and intra-operative imaging ...
