A Low‐Cost, Handheld Optical Stiffness Sensor for Minimally Invasive Surgery

Advanced Robotics Research, EarlyView.
A novel handheld stiffness sensor is presented for real‐time tissue stiffness characterization. By simultaneously sensing contact force and tissue deformation, the device enables accurate stiffness quantification without requiring precise manual control. This approach offers a promising solution for intraoperative tumor detection and minimally invasive

Variation in tissue outcome of ovine and human engineered heart valve constructs : relevance for tissue engineering

, 2012
AIM: Clinical application of tissue engineered heart valves requires precise control of the tissue culture process to predict tissue composition and mechanical properties prior to implantation, and to understand the variation in tissue outcome.

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Ultrasound of soft tissue masses of the hand [PDF]

, 2012
Most soft tissue mass lesions of the hand are benign. Ganglia are the commonest lesions encountered, followed by giant cell tumors of the tendon sheath. Malignant tumors are rare. Often a specific diagnosis can be achieved on imaging by considering the

The importance of internal strain as opposed to interface pressure in the prevention of pressure related deep tissue injury

, 2010
For pressure ulcer prevention an ambitious goal would be the establishment of a mechanical threshold for tissue damage. In the past, several researchers have sought to establish such a threshold often involving the loading time.

Low oxygen concentrations impair tissue development in tissue-engineered cardiovascular constructs

, 2012
Cardiovascular tissue engineering has shown considerable progress, but in vitro tissue conditioning to stimulate the development of a functional extracellular matrix still needs improvement.

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

Multilayered connective tissue grafting technique: Case description of a novel soft tissue augmentation approach of 16 months follow-up

, 2020
BACKGROUND: Management of failed augmentation cases can be quite challenging to clinicians, because they might result in a more pronounced alveolar ridge defect.

Substrates for cardiovascular tissue engineering

, 2011
Cardiovascular tissue engineering aims to find solutions for the suboptimal regeneration of heart valves, arteries and myocardium by creating ‘living’ tissue replacements outside (in vitro) or inside (in situ) the human body.
