Intensity Correction Method Customized for Multi-animal Abdominal MR Imaging with 3T Clinical Scanner and Multi-Array Coil

Magnetic Resonance in Medical Sciences, 2013
Simultaneous magnetic resonance (MR) imaging of multiple small animals in a single session increases throughput of preclinical imaging experiments. Such imaging using a 3-tesla clinical scanner with multi-array coil requires correction of intensity variation caused by the inhomogeneous sensitivity profile of the coil.

Deep‐Learning‐Driven High‐Fidelity In Vivo Hyperspectral Fluorescence Imaging Under Extreme Photon‐Limited Conditions

Advanced Science, EarlyView.
Highly overlapping fluorescent signals become distinguishable in photon‐limited living organisms via advanced imaging with intelligent reconstruction. The resulting in vivo hyperspectral imaging capability reveals nanoplastic uptake and circulation in live zebrafish, providing a new approach for studying complex biological and environmental processes ...

The Regeneration Potential after Human and Autologous Stem Cell Transplantation in a Rat Sciatic Nerve Injury Model can be Monitored by MRI

Cell Transplantation, 2015
Traumatic nerve injuries are a major clinical challenge. Tissue engineering using a combination of nerve conduits and cell-based therapies represents a promising approach to nerve repair. The aim of this study was to examine the regeneration potential of

In vivo magnetic resonance imaging of mice liver tumors using a new gadolinium-based contrast agent

Kaohsiung Journal of Medical Sciences, 2013
We compared the enhancement effect between a newly synthesized tissue-specific contrast agent, [Gd-DOTA-FPβG], and a commercially available agent, [Gd(DOTA)]−, in a murine model of liver tumor using a clinical magnetic resonance imaging scanner.

Rhoifolin Alleviates Ulcerative Colitis by Targeting NMNAT1 and Activating SIRT1‐FOXO1 Signaling to Enhance ILC3s Effector Function

Advanced Science, EarlyView.
Rhoifolin directly targets NMNAT1, thereby activating nicotinamide salvage pathway and promoting intracellular NAD+ biosynthesis. Elevated NAD+ levels enhance SIRT1 activity, leading to FOXO1 deacetylation and nuclear translocation. Nuclear FOXO1 subsequently binds to the IL‐22 promoter, upregulating IL‐22 transcription and potentiating ILC3 effector ...

A large urachal cyst presenting with lower urinary tract symptoms and a falsely elevated post-void residual on bladder scan

Urology Case Reports
The urachus is an embryologic remnant that connects the bladder to the umbilicus and typically obliterates during gestation. Urachal cysts are one of the most common congenital urachal anomalies.

Engineering Morphological Anisotropy to Control the In Vivo Transport Dynamics, Clearance, and Biodistribution of Silica Nanocarriers

Advanced Science, EarlyView.
Morphological anisotropy directs the in vivo transport under physiological flow and clearance of silica nanocarriers. Increasing anisotropy reduces cellular uptake, suppresses hepatic and splenic sequestration, and prolongs systemic circulation by steering particles toward the central flow core.

Une cytolyse hépatique révélant un ganglioneurome surrénalien

The Pan African Medical Journal, 2014
Le ganglioneurome est une tumeur nerveuse bénigne rare, d'origine neuroectodermique et de localisation rétropéritonéale fréquente. Nous rapportons l'observation d'un patient de 55 ans dont la tumeur est révélée fortuitement sur une échographie abdominale

Chimeric IL‐6/4R‐LL37 Engineered Macrophages Achieve Synchronized Inflammation Control and Antimicrobial Defence in Sepsis

Advanced Science, EarlyView.
Engineered macrophages programmed in situ by LNP‐delivered IL‐6/4 fusion and LL37 mRNAs simultaneously dampen cytokine storm, promote M2‐like repair, and enhance direct bacterial killing in sepsis. This combinatorial strategy restores T cell and macrophage function, lowers organ bacterial burden, and improves survival, highlighting a precision, host ...
