The mechanical properties of skin are important tissue parameters that useful for understanding patho-physiology, which can aid disease diagnosis and treatment. This paper presents an innovative method employs phase-sensitive spectral-domain optical coherence tomography (PhS-OCT) to characterize the biomechanical by measuring surface waves induced short impulses from a home-made shaker. Experiments carried out on single double-layer agar–agar phantoms, different concentrations thickness, in...
We report on a noninvasive and noncontact all-optical method to measure the elasticity of cornea. use pulsed laser excite surface acoustic waves (SAW) that propagate corneal surface, then phase-sensitive optical coherence tomography system remotely record SAWs from which is estimated. In addition, able provide real-time tomographic images cornea being examined, an important consideration for clinical studies. While precisely maintaining range intraocular pressures (IOP), series measurements...
We report on a quantitative elastography technique achieved by combining phase-sensitive optical coherence tomography (PhS-OCT) with the surface acoustic wave (SAW) method. Different from traditional elastography, is impulse-stimulated SAW, rather than shear waves. PhS-OCT serves not only as detector to measure SAW signals but also means provide cross-sectional image of sample. The experimental results indicate that combination feasible heterogeneous tissue samples.
Granular hydrogel matrices have shown significant advantages in mesenchymal stem cell (MSC) delivery and tissue ingrowth due to their minimally invasive injection capabilities porous structures. However, creating granular hydrogels that simultaneously mimic the nanofilamentous architecture of natural extracellular matrix (ECM) enhance retention vivo immunoregulation a diabetic microenvironment remains challenging. In this study, we present nanoengineered supramolecular with nanofibrillar...
We report on a noncontact photoacoustic imaging (PAI) technique in which low-coherence interferometer [(LCI), optical coherence tomography (OCT) hardware] is utilized as the acoustic detector. A synchronization approach used to lock LCI system at its highly sensitive region for detection. The experimentally verified by of scattering phantom embedded with hairs and blood vessels within mouse ear vitro. system's axial lateral resolutions are evaluated 60 30 μm, respectively. experimental...
Advances in the field of laser ultrasonics have opened up new possibilities medical applications. This paper evaluates this technique as a method that would allow for rapid characterization elastic properties soft biological tissue. In doing so, we propose novel approach utilizes low coherence interferometer to detect laser-induced surface acoustic waves (SAW) from tissue-mimicking phantoms. A Nd:YAG focused line-source is applied one- and two-layer agar-agar phantoms, generated SAW signals...
Breast cancer is one of the rapidly increasing cancers among women and a significant cause cancer-related morbidity mortality worldwide. Therefore, current study was designed to examine compare trends breast incidence (BCI) during observed period (1990-2015) in specific age groups investigate age-specific, time period, birth cohort-related effects on BCI China, India, Pakistan, Thailand.Data related were retrieved from Institute for Health Metrics Evaluation. Age-period-cohort model joint...
Objectives: Upper tract urothelial carcinoma is a rare, aggressive lesion, with early detection key to its management. This study aimed utilise computed tomographic urogram data develop machine learning models for predicting tumour grading and staging in upper patients compare these predictions histopathological diagnosis used as reference standards. Methods: Protocol-based from 106 were obtained visualised 3D. Digital segmentation of the tumours was conducted by extracting textural...
A series of ordered photoanodic architectures (including TiO2 nanotube arrays (TNT), ZnO nanorods, ZnO/TiO2 core/shell nanostructures) for CdS/CdSe sensitized solar cells (QDSCs), were fabricated directly on transparent conductive oxide glasses by a facile sol–gel assisted template process. The morphologies, optical and electrical properties TNTs co-sensitized have been demonstrated. effect CdSe deposition time the cell performance was clarified, growth mechanism quantum dots surface has...
Dynamic optical coherence elastography (OCE) tracks elastic wave propagation speed within tissue, enabling quantitative three-dimensional imaging of the modulus. We show that propagating mechanical waves are mode converted at interfaces, creating a finite region on order an acoustic wavelength where there is not simple one-to-one correspondence between and Depending details boundary’s geometry elasticity contrast, highly complex fields produced near boundary can substantially affect both...
Metal-organic frameworks (MOFs) have been proven promising in addressing many critical issues related to gas separation and purification. However, it remains a great challenge optimize the pore environment of MOFs for purification specific mixtures.

Traditional high-quality OCTA images require multi-repeated scans (e.g., 4-8 repeats) in the same position, which may cause patient to be uncomfortable. We propose a deep-learning-based pipeline that can extract from only two-repeat OCT scans.
