Fractal Anatomy of Human Organs: A Narrative Review of Structure, Function, and Clinical Perspectives

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Fractal geometry describes complex, self‐similar patterns that repeat across spatial scales and is increasingly recognized as relevant in anatomical research. Indeed, the fractal organization is consistently observed in respiratory, cardiovascular, gastrointestinal, nervous, renal, hepatic, and dermatological systems.

Contemporary and Emerging Therapies in the Management of Refractory Angina: A Clinical Review

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Refractory angina (RA) represents a growing challenge in clinical cardiology, particularly in patients with obstructive coronary artery disease (CAD) who remain symptomatic despite optimal medical therapy and who are not candidates for revascularization.

Endovascular Stenting for Pulmonary Vein Stenosis Following Atrial Fibrillation Ablation: From Diagnosis to Intervention

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Pulmonary vein stenosis (PVS) is an uncommon but serious complication of atrial fibrillation (AF) ablation, often misinterpreted as primary pulmonary disease. Timely identification is essential to prevent irreversible injury and to guide appropriate referral for interventional management. Case Presentations Through the discussion of

Advances in Triboelectric Nanogenerators With Rotating Structure

open access: yesCarbon Energy, EarlyView.
The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

Can ISO/IEC 17025 serve as a tool to prevent scientific fraud in chemical research laboratories?

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Scientific fraud has been documented across multiple disciplines, and chemistry is no exception. Recent studies indicate that contamination of materials, methodological errors, and unreliable data, results, or analyses account for over 25% of retracted publications.

Modeling Supports Combinatorial Effects Between Pharmacological and Non‐Pharmacological Interventions to Prevent Opioid‐Induced Cardiac Arrest

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Few studies have quantified the effects of non‐pharmacological interventions (e.g., rescue breathing) in the setting of community opioid overdose. We extended a previously validated model for opioid antagonists by incorporating the mechanism of rescue breathing, and quantified combinatorial effects between rescue breathing and various formulations of ...

Iron and Nickel Substituted Perovskite Cobaltites for Sustainable Oxygen Evolving Anodes in Alkaline Environment

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

Experimental study on burning rate and flame geometry in construction tunnel fires under high geothermal conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...
