Real Time Evaluation of Whole Organ Perfusion by Magnetic Resonance Imaging in Ex Vivo Machine‐Perfused Liver

NMR in Biomedicine, Volume 39, Issue 3, March 2026.
Porcine livers underwent mechanical perfusion inside an MRI scanner, enabling dynamic quantitative measurements of whole organ perfusion. Vascular segmentation down to 0.45 mm resolution allowed quantification of morphological features such as vessel tortuosity, while Dynamic Contrast Enhanced MRI and diffusion weighted imaging was used to produce ...

Nipple‐Originating Solid Papillary Carcinoma In Situ: A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Solid papillary carcinoma of the breast is a rare histopathological subtype of papillary neoplasms, and its in situ variant localized to the nipple is particularly uncommon. Current oncology literature provides limited evidence on standardized diagnostic criteria, biological behavior, and optimal treatment strategies for this entity.

The surface accessibility of α-bungarotoxin monitored by a novel paramagnetic probe [PDF]

, 2011
The surface accessibility of {alpha}-bungarotoxin has been investigated by using Gd2L7, a newly designed paramagnetic NMR probe. Signal attenuations induced by Gd2L7 on {alpha}-bungarotoxin C{alpha}H peaks of 1H-13C HSQC spectra have been analyzed and ...

Efficacy and Safety of Hypofractionated Radiation Therapy Combined With Immunotherapy for Hepatocellular Carcinoma With Vp4 Portal Vein Tumor Thrombosis

Hepatology Research, Volume 56, Issue 2, Page 246-252, February 2026.
ABSTRACT Background Hepatocellular carcinoma (HCC) with Vp4 portal vein tumor thrombosis (PVTT) has an extremely poor prognosis, and evidence for effective systemic therapy is limited. Preclinical studies suggest that hypofractionated radiation therapy (HFRT) may enhance immune checkpoint inhibitor (ICI) efficacy through immunogenic cell death and ...
