Thermo‐Fluorescent Bactericidal Quantum Dots Based Smart Multifunctional Textiles via Molecular Surface Engineering and 3D‐Printed Interlocked Architectures

Advanced Healthcare Materials, EarlyView.
A versatile approach is presented for fabricating smart multifunctional textiles by integrating thermo‐fluorescent carbon dot/polymer nanocomposite coatings with 3D‐printed interlocked architectures. The fabrics exhibit temperature‐responsive fluorescence, durable hydrophobicity, strong antibacterial and antioxidant activity, and enhanced UV protection.

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

Advanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Extracellular Vesicles Modulation by an Adiponectin Receptor Agonist Provides Cardioprotection for Myocardial Ischemic Injury

Advanced Healthcare Materials, EarlyView.
This study demonstrates that ALY688, a drug mimicking the heart‐protective hormone adiponectin, reduces myocardial ischemia injury. ALY688 increases the production of extracellular vesicles, which carry protective cargo including adiponectin itself.

Noise in ultrasonic imaging

Ultrasonics, 1980
The feasibility of noise measurement in medical ultrasonic imaging has been studied and a theoretical evaluation of stochastic noise influence upon the perceived image has been undertaken. The influence of noise on a perceived image has been calculated by considering the light intensity perception characteristic of the human eye and it has been found ...

Digitization of Ultrasonic Images

Radiology, 1970
Abstract The authors describe a method for digitizing diagnostic ultrasonic data using a system originally constructed for use with radioisotope scan data. A commercial ultrasonic unit drives the transducer and amplifies the preliminary echo signal. The output signals from the ultrasonic unit are fed to a programmable digital logic interface coupled to

Ultrasonic imaging of neoplasms

Cancer, 1976
Reflected ultrasound scanning (echography) is rapidly developing into a prime tool for tumor diagnosis, outlining, and detection. The principles of echographic diagnosis of neoplasms, the accepted uses in detection and diagnosis, as well as some of the principles of internal and contour patterns are discussed.

Ultrasonic imaging method and ultrasonic imaging apparatus

The Journal of the Acoustical Society of America, 2004
Since a number of ultrasonic beams which are transmitted within unit time is increased, an ultrasonic imaging method is capable of obtaining image information in a high frame rate or improving resolution of the image information. In an ultrasonic imaging method of transmitting an ultrasonic beam toward a measurement target located within an object ...
