Inflammation induced by snake venoms optimizes envenomation

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustrating mechanisms underlying direct vascular absorption and subsequent movement of venom toxins into the tissues consequent to snakebite. A, snakebite into prey deposits venom toxins into the tissue interstitium, with the venom then causing acute inflammation primarily in venules.

Quantitative Imaging of Pyruvate Metabolism in a Patient With Anaplastic Thyroid Cancer

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 826-838, August 2026.
ABSTRACT Purpose Magnetic resonance imaging using hyperpolarized (HP) [1‐13C]‐pyruvate enables assessment of pyruvate metabolism in vivo and offers new insight into metabolic changes in response to cancer therapy. Widely used semi‐quantitative metrics of pyruvate metabolism can be affected by physiological factors that are extrinsic to intracellular ...

Imaging Venous Transit Time and Blood–Brain Barrier Permeability of the Deep Brain

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 809-816, August 2026.
ABSTRACT Purpose Imaging of venous vessels with advanced pulse sequences allows the assessment of important hemodynamic parameters. Previous work has measured venous transit time (VTT) and blood–brain barrier (BBB) water permeability in cortical tissue.

Design of Differential Single‐Block and Multi‐Block Presaturated Ultrashort Echo Time Pulse Sequences for Fast and Flexible Short‐T2 Imaging

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 711-726, August 2026.
ABSTRACT Purpose Ultrashort echo time (UTE) techniques are essential for the magnetic resonance imaging of short‐T2 signals. Current UTE techniques are time‐consuming and often require the acquisition of an inflexible volume. In this work, we implement new UTE sequences—differential single‐block presaturated UTE (δSB‐UTE) and differential multi‐block ...

Hyperpolarized MRI Detects Increased [1‐13C]Pyruvate Metabolism in Early Liver Regeneration

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Hyperpolarized [1‐13C]pyruvate MRI detected increased pyruvate‐to‐lactate and pyruvate‐to‐alanine exchange during early liver regeneration following 70% partial hepatectomy in rats. These findings support the use of hyperpolarized MRI for noninvasive assessment of regenerative metabolism.

Characterizing Metabolic and Compositional Heterogeneity of Calf Muscle Using CEST MRI at 3 T

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
This study used 3 T CEST MRI to characterize metabolic and compositional heterogeneity in eight healthy calf muscles, focusing on amide, PCr, rNOE, and MT contrasts. Distinct signatures emerged between deep stabilizer and superficial powerhouse muscles. Significant correlations with age, fat content, BMI, and strength (e.g., rNOE vs. strength) revealed
