Spinal Cord, 2018 • October 1, 2018
This study evaluated the reproducibility of total and regional DXA-derived body composition values in individuals with spinal cord injury (SCI). The study assessed both short-term (same day) and long-...
KEY FINDING: Short-term precision: The RMS-CV% for each region did not exceed 5.6%, 2.7%, 3.8%, 6.5%, 5.8% and 2.3% for arms, legs, trunk, android and gynoid regions and total body mass, respectively.
Neural Regen Res, 2018 • March 1, 2018
This study evaluated the effects of 125I radioactive seed implantation on the spinal cord of rabbits using diffusion tensor imaging (DTI) and pathological analysis. The results indicated that higher r...
KEY FINDING: Increased radiation dose (D90) correlated with aggravated pathological damage of neurons and microvessels in the gray matter and white matter.
The Journal of Spinal Cord Medicine, 2019 • July 1, 2019
This study evaluated the accuracy of DXA in quantifying trunk lean mass compared to MRI in men with SCI. The results showed that DXA overestimated trunk lean mass when compared to MRI. The study also ...
KEY FINDING: DXA overestimated trunk lean mass compared to MRI measurements. Trunk LM-DXA (24 ± 3.3 kg) and android LM-DXA (3.6 ± 0.7 kg) overestimated (P < 0.0001) trunk LM-MRI (1.7 ± 0.5 kg).
Photoacoustics, 2021 • March 10, 2021
This study demonstrates the feasibility of using photoacoustic time-frequency spectral analysis (PA-TFSA) to characterize bone mineral density (BMD) and bone microstructure. The results show that oste...
KEY FINDING: Osteoporotic bone samples with lower BMD and thinner MTT exhibit higher frequency components in PA-TFSA.
Scientific Reports, 2023 • September 26, 2023
This study investigates the feasibility of using ultrasound elastography (USE) to assess spinal cord injury (SCI) in a rabbit model in vivo. The researchers compared USE measurements with histological...
KEY FINDING: USE strain ratios were significantly higher in paralyzed rabbits compared to non-paralyzed rabbits, indicating differences in spinal cord mechanical properties.
Reumatologia, 2017 • April 1, 2017
Cervical spine involvement is common in rheumatoid arthritis (RA) and can lead to various types of instability, potentially causing neurological complications. Early identification of these instabilit...
KEY FINDING: Plain radiographs are a common initial imaging method due to their availability and low cost, particularly for assessing atlanto-axial joint anomalies using functional radiographs in flexion and extension.
The Journal of Neuroscience, 2017 • November 8, 2017
In vivo optical imaging has revolutionized the study of cellular responses to injury and disease in the CNS, providing insights into axonal degeneration/regeneration, glial responses, neuroinflammatio...
KEY FINDING: In vivo imaging reveals reversible axon damage in clinically relevant models of CNS injury and disease, suggesting axonal rescue as a promising therapeutic strategy.
Photoacoustics, 2022 • December 14, 2021
This study investigates the feasibility of using photoacoustic physicochemical spectrograms (PCSs) for bone health assessment, focusing on variations in bone mineral density (BMD), bone microarchitect...
KEY FINDING: PAPCA can effectively characterize both the microstructure and content of multi-biomarkers highly related to bone health.
Biology Open, 2019 • December 2, 2019
This paper presents an algorithm that automatically characterizes the level of damage to the spinal cord of a Xenopus laevis froglet by analyzing swimming videos. The algorithm measures the position o...
KEY FINDING: The system effectively characterizes spinal cord damage with 97% accuracy by tracking limb movements and extracting kinematic features.
Journal of Cerebral Blood Flow & Metabolism, 2012 • May 2, 2012
This review discusses the principles of neuroinflammation, focusing on the role of microglia and common neurologic disease mechanisms. It also highlights the molecular targets currently used and explo...
KEY FINDING: Microglial activation, a key component of neuroinflammation, can be imaged using TSPO-targeting tracers in various neurological diseases.
