Cortical Microvascular Pulsatility in the Aging Mouse Brain and the Confounding Effects of Anesthesia

open access: yesAdvanced Science, EarlyView.
Multi‐modal optical imaging reveals microvascular pulsatility in the brain cortex of awake and anaesthetized mice. Awake hemodynamics in male mice are found to be remarkably stable until late life, with flow pulsatility being significantly higher than in females, despite similar average perfusion.

Acute Scrotum Management: The Significance of Color Doppler Ultrasound

open access: yesMedical Journal of Babylon
Background: It is important to distinguish with certainty between surgical and nonsurgical treatments for acute scrotal pain. It is widely recognized that early surgery for testicular salvage in ischemic disease, particularly torsion of the testis ...

The delta Doppler technique for LDV measurements at long distances [PDF]

open access: yes
A technique for measuring velocity, referred to as a Delta Doppler technique, was presented. This technique determines scattering source velocities by measuring the difference in Doppler shifts of two different frequencies.

Amelioration of Post‐Stroke Edema and Microcirculatory Dysfunction via Targeted AQP4 Inhibition While Preserving the Glymphatic System

open access: yesAdvanced Science, EarlyView.
Compared to untargeted therapy, the targeted nanocarrier, Angiopep‐2‐conjugated Lipid Nanoparticle (A‐LNP) loaded with TGN‐020 (TGN), selectively accumulated in stroke‐injured regions. It suppressed local aquaporin‐4 (AQP4) overexpression, thereby alleviating cerebral edema and hypoperfusion while preserving global glymphatic clearance.

Migrasomes in Ischemic Stroke: Molecular Landscape and Pathophysiological Impact

open access: yesAdvanced Science, EarlyView.
Multi‐omics profiling of stroke patients exposes systemic molecular fingerprints of immune activation, oxidative stress and metabolic collapse. Complement and coagulation cascade, and cholesterol metabolism emerge as shared functional hallmarks of plasma migrasomes in stroke patients and migrasomes isolated from experimental stroke mice.

Spin Matters: A Multidisciplinary Roadmap to Understanding Spin Effects in Oxygen Evolution Reaction During Water Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
This roadmap offers a forward‐looking perspective on spin enhancement in the oxygen evolution reaction. It highlights how combining systematic experiments, advanced computational modeling, and novel magnetic, chiral, or hybrid materials can deepen the understanding of spin‐dependent catalytic mechanisms.

Intraoperative Evaluation of Bladder Perfusion Using Indocyanine Green Fluorescence Imaging During Total Pelvic Exenteration After Interruption of Blood Flow From the Internal Iliac Vessels

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
Intraoperative ICG fluorescence imaging demonstrated that bladder perfusion was maintained through blood flow from the pubic side, even after complete division of the internal iliac vessels during total pelvic exenteration. ABSTRACT Background In lateral lymph node dissection (LLND) for locally advanced or recurrent rectal cancer, concomitant resection
