Dual-energy Computed Tomography Imaging from Contrast-enhanced Single-energy Computed Tomography [PDF]

open access: yesarXiv, 2020
In a standard computed tomography (CT) image, pixels having the same Hounsfield Units (HU) can correspond to different materials and it is therefore challenging to differentiate and quantify materials. Dual-energy CT (DECT) is desirable to differentiate multiple materials, but DECT scanners are not widely available as single-energy CT (SECT) scanners ...

Reduced iodinated contrast media dose and injection speed for CT: how much does this decrease the risk of a hypersensitivity reactions?

open access: yesQuantitative Imaging in Medicine and Surgery, 2020
Adverse reactions developing after administration of iodinated contrast media (ICM) can either constitute hypersensitivity reactions, toxic reactions, or even events unrelated to ICM exposure, such as acute spontaneous or infection-induced urticaria (1).

Lipid Droplet‐Organized MDM2‐Mediated P53 Degradation: A Metabolic Switch Governing Diet‐Driven Tumor Progression

open access: yesAdvanced Science, EarlyView.
Tumor‐associated TP53 inactivation correlates with lipid droplet (LD) accumulation. High‐fat diets drive Cyb5r3‐Myh9‐mediated p53 enrichment on LD surfaces, accelerating its degradation while upregulating LD‐promoting factor CD36 expression to establish a feed‐forward loop. LD suppression or dietary intervention restores p53 and inhibits tumorigenesis,

"Synergistic Effect of Intravenous Immunoglobulins and Iodinated Contrast Media on Renal Function "

open access: yesIranian Journal of Allergy, Asthma and Immunology, 2004
Acute renal failure is one of the side effects while using intravenous immunoglobulins. This complication is also observed with iodinated contrast media.

Strong and Fatigue‐Resistant Hydrogels via Poor Solvent Evaporation Assisted Hot‐Stretching for Tendon Repair

open access: yesAdvanced Science, EarlyView.
An anisotropic hydrogel (AHs) is prepared in this study. The strength of AHs can reach up to 33.14 ± 2.05 MPa, and it exhibits unique defect‐insensitive characteristics. Cracks can only deflect along the fiber alignment direction, demonstrating an interesting self‐protection function.

Effect of intravenous infusion of iodinated contrast media on the coronary blood flow in dogs

open access: yesInternational Journal of Cardiology: Heart & Vasculature, 2016
Background: Coronary computed tomography angiography (CCTA) is obtained using peripheral intravenous iodinated contrast agents (ICA) injection. There is continuing attempts to derive coronary physiological information like coronary blood flow (CBF) and ...

DNA Origami‐Based CD44‐Targeted Therapy Silences Stat3 Enhances Cartilage Regeneration and Alleviates Osteoarthritis Progression

open access: yesAdvanced Science, EarlyView.
This study develops a cartilage‐targeted DNA origami system (OCS) that protects and delivers si‐Stat3 to chondrocytes. OCS reduces MMP13 expression, enhances extracellular matrix stability, and lowers oxidative stress while improving cell survival. In vivo, OCS decreases cartilage degradation biomarkers and promotes tissue repair factors, demonstrating

K-edge subtraction vs. A-space processing for x-ray imaging of contrast agents: SNR [PDF]

open access: yesarXiv, 2017
Purpose: To compare two methods that use x-ray spectral information to image externally administered contrast agents: K-edge subtraction and basis-function decomposition (the A-space method), Methods: The K-edge method uses narrow band x-ray spectra with energies infinitesimally below and above the contrast material K-edge energy.

Decoupling Ultralow Coherent and Particle‐Like Phonon Transport via Bonding Hierarchy in Soft Superionic Crystals

open access: yesAdvanced Science, EarlyView.
The bonding hierarchy in X6Re6S8I8 (X = Rb, Cs) promotes phonon localization, generating extensive discrete phonon flat bands that redefine the lower bounds of lattice thermal conductivity in crystals. Abstract Within the unified theoretical framework for thermal transport, the inherent interplay between coherent tunneling and propagative phonon ...
