Pain and Perception: Exploring Psychedelics as Novel Therapeutic Agents in Chronic Pain Management.
Curr Pain Headache Rep
January 2025
Advanced Wellness and Pain, Scottsdale, AZ, USA.
Purpose Of Review: Chronic pain affects approximately 1.5 billion people worldwide, representing the leading cause of disability and a significant financial burden on healthcare systems. Conventional treatments, such as opioids and non-steroidal anti-inflammatory drugs, are frequently linked to adverse effects, including dependency and gastrointestinal issues, and often offer limited long-term relief.

Recent studies of the spread of substances penetrating the disrupted blood-brain barrier have revealed that the spread in the parenchyma surrounding a vessel has a complex character. In particular, a flow-like motion occurred for a short time that exhibits a smooth transition to diffusional spread. To address the possible physical background of such behavior, we created a system formed by a hydrogel medium with a channel filled by a marker solution, which can serve as a physical model mimicking the process of a substance passively spreading to the brain's parenchyma when the blood-brain barrier is disrupted.

Magn Reson Med Sci
November 2024
Department of Radiology and Neuroradiology, University Hospital Schleswig-Holstein Campus Kiel, Kiel, Schleswig-Holstein, Germany.
Purpose: The aim of our study was to investigate the technical accuracy of susceptibility-weighted imaging (SWI) and quantitative susceptibility mapping (QSM) created to detect intramammary-like calcifications depending on different TEs, volume, and type of calcification samples at 1.5T.
Methods: Jello-embedded particles of blackboard chalk and ostrich eggshell ranging in size from 4 to 25 mm were used to simulate intramammary calcifications after testing different base substances and calcifications for their suitability to be used in breast phantoms.
[A Novel Support Material for MRI Phantom Study].

November 2024
Department of Radiology, Kurihara Municipal Wakayanagi Hospital.
Purpose: For MRI phantom experiments, when a support such as agar is used to fix a container holding a substance to be measured, difficulties arise, such as the time and effort for support preparation and material changes occurring over time. We specifically examined super absorbent polymer (SAP) and confirmed the usefulness of SAP as a new support for MRI phantoms in terms of measurement and changes over time.
Methods: The simplicity of preparing SAP as a support, its influence on the measured values of substances, and its changes over time were compared with those of agar.
Rapid wideband characterization of viscoelastic material properties by Bessel function-based time harmonic ultrasound elastography (B-THE).

Elastography is an emerging diagnostic technique that uses conventional imaging modalities such as sonography or magnetic resonance imaging to quantify tissue stiffness. However, different elastography methods provide different stiffness values, which require calibration using well-characterized phantoms or tissue samples. A comprehensive, fast, and cost-effective elastography technique for phantoms or tissue samples is still lacking.
