A therapeutic relay strategy enabled by spatiotemporally programmable nanoplatforms for multilayered cardioprotection against MI/RI

Journal of Nanobiotechnology
Myocardial ischemia/reperfusion injury (MI/RI) is driven by a cascade of pathological events, including oxidative stress and the activation of novel cell death pathways such as ferroptosis.

Sparsity driven ultrasound imaging [PDF]

The Journal of the Acoustical Society of America, 2012
An image formation framework for ultrasound imaging from synthetic transducer arrays based on sparsity-driven regularization functionals using single-frequency Fourier domain data is proposed. The framework involves the use of a physics-based forward model of the ultrasound observation process, the formulation of image formation as the solution of an ...

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

FEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Ultrasound imaging in reproductive medicine [PDF]

, 2012
One in six couples seeks help for infertility during their reproductive years. Subfertility investigations should be performed without delays (because female fertility decreases with age) and should be as noninvasive as possible.

Diagnostic performance of intestinal ultrasound compared with CT enterography in Crohn’s disease: single-center experience

Frontiers in Medicine
AimThis study aimed to clarify the diagnostic value of transabdominal bowel ultrasonography (TBUS) examination for identifying the location of Crohn’s disease (CD) lesions and their complications in relation to computed tomography enterography (CTE ...

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

FEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

The frequency-dependent directivity of a planar Fabry-Perot polymer film ultrasound sensor [PDF]

, 2007
A model of the frequency-dependent directivity of a planar, optically-addressed, Fabry-Perot (FP), polymer film ultrasound sensor is described and validated against experimental directivity measurements made over a frequency range of 1 to 15 MHz and ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Development of High Frequency Annular Array with a Novel Structure for Medical Imaging [PDF]

, 2010
High frequency annular arrays offer a number of advantages in medical imaging. A novel 2mm diameter, 7-element, 40MHz array using equal width elements, instead of the more conventional equal area ones, has been designed and evaluated.
