Comparisons of Different CEST Quantification Metrics Applied in Acute Parkinson's Disease Mouse Model

Chinese Journal of Magnetic Resonance, 2019
Non-invasive and quantifiable diagnosis of Parkinson's disease (PD) is an ongoing challenge for researchers. In this study, we compared two different chemical exchange saturation transfer (CEST) imaging quantification metrics in substantia nigra (SN ...

Redox‐dependent binding and conformational equilibria govern the fluorescence decay of NAD(P)H in living cells

FEBS Letters, EarlyView.
In this work, we reveal how different enzyme binding configurations influence the fluorescence decay of NAD(P)H in live cells using time‐resolved anisotropy imaging and fluorescence lifetime imaging microscopy (FLIM). Mathematical modelling shows that the redox states of the NAD and NADP pools govern these configurations, shaping their fluorescence ...

Intraoperative Functional Ultrasound Imaging of Human Brain Activity

Scientific Reports, 2017
The functional mapping of brain activity is essential to perform optimal glioma surgery and to minimize the risk of postoperative deficits. We introduce a new, portable neuroimaging modality of the human brain based on functional ultrasound (fUS) for ...

DCE and DSC perfusion MRI diagnostic accuracy in the follow-up of primary and metastatic intra-axial brain tumors treated by radiosurgery with cyberknife

Radiation Oncology, 2019
Background The differential diagnosis between radiation necrosis, tumor recurrence and tumor progression is crucial for the evaluation of treatment response and treatment planning.

Active Contour Models for Manifold Valued Image Segmentation [PDF]

, 2013
Image segmentation is the process of partitioning a image into different regions or groups based on some characteristics like color, texture, motion or shape etc. Active contours is a popular variational method for object segmentation in images, in which

Neutrophil deficiency increases T cell numbers at the site of tissue injury in mice

FEBS Letters, EarlyView.
In wild‐type mice, injury or acute inflammation induces neutrophil influx followed by macrophage accumulation. Mcl1ΔMyelo (neutrophil‐deficient) mice lack neutrophils, and in response to muscle injury show fewer macrophages and exhibit strikingly elevated T‐cell numbers, primarily non‐conventional “double‐negative” (DN) αβ and γδ T cells.
