The paper presents the first scientific study of quasi-linear viscoelastic (QLV) model poly(vinyl alcohol) (PVA) sponges. PVA sponges have been considered as a potential implant material for replacement and repair soft tissues, including cartilage, liver kidney. It is also used in ophthalmic surgical treatment, such Lasik, cataract refractive surgeries, to manipulate tissue during incision procedures eye absorb fluid. However, critical barrier use sponge lack sufficient mechanical...

Atherosclerosis is the most common arterial disease. It has been shown that stresses are induced during blood circulation can cause plaque rupture and, in turn, lead to thrombosis and stroke. In this study, finite element method used predict vulnerability based on peak stress using human samples. A total of 23 healthy atherosclerotic coronary arteries 14 9 patients excised within 5 h postmortem. The samples mounted an uniaxial tensile test machine, obtained mechanical properties...

Atherosclerosis is a disease in which plaque builds up inside arteries. It also considered as one of the most serious and common forms cardiovascular can lead to heart attack stroke. In current research, finite element method used anticipate vulnerability based on peak stress using human samples. A total 23 healthy atherosclerotic coronary arteries, including 14 9 are removed within 5 h postmortem. The samples mounted uniaxial tensile test machine obtained mechanical properties models....

Coronary artery disease is responsible for a third of global deaths worldwide. Computational simulations blood flow can be used to understand the interactions artery/plaque and in coronary better predict rupture atherosclerotic plaques. So far, mechanical properties animals' have been mostly hemodynamic simulation arteries. The arteries are often not accurate enough only an approximate estimation comparative assessment cognate parameters human. In this study, three-dimensional (3D)...

Abstract Gelatin (Gel) has been reported as a promising candidate in tissue engineering owing to its easy availability, biocompatibility, and biodegradability. Gel hydrogel is of potential be cross-linked with different materials enhance their biocompatibility for cell culture applications. The mechanical properties this versatile material, however, have not thoroughly determined. In study, the linear elastic (Young’s modulus maximum stress) non-linear hyperelastic (hyperelastic...

The zona pellucida (ZP) is the spherical layer that surrounds mammalian oocyte. physical hardness of this plays a crucial role in fertilization and largely unknown because lack appropriate measuring modelling methods. aim study to measure biomechanical properties ZP human/mouse ovum test hypothesis Young's modulus varies with fertilization. moduli are determined before after by using micropipette aspiration technique, coupled theoretical models oocyte as an elastic incompressible half-space...

As a main cause of mortality in developed countries, Coronary Artery Disease (CAD) is known as silent killer with considerable cost to be dedicated for its treatment. Bypass Graft (CABG) common remedy CAD which different blood vessels are used detour. There lack knowledge about mechanical properties human CABG, and while these have great impact on long-term patency CABG. Thus, studying properties, especially those umbilical veins not been considered yet, looks utterly necessary.Umbilical...

Cervical cancer, primarily caused by the human papillomavirus (HPV), remains a significant global health issue, especially in underserved regions. Despite availability of screening methods, barriers such as limited access and resource constraints contribute to late-stage diagnoses high mortality rates. This study introduces novel platform utilizing centrifugal microfluidics automate labor-intensive Pap smear staining process, providing cost-effective accessible solution. The system features...

Degenerative and demyelinating diseases are known to alter the mechanical properties of brain tissue. While few studies have characterized these biomechanical changes, it is clear that accurate characterization diseased tissue could be a substantial asset neuronavigation surgery simulation through haptic devices. In this study, samples from rats infected with Plasmodium berghei ANKA, an African murine malaria parasite, evaluated using uniaxial tensile test machine. Infected brains having...

The stresses induced within plaque tissues and arterial layers during stent expansion inside an atherosclerotic artery can be exceeded from the yield of those and, consequently, lead to or layer rupture. distribution magnitude in each component involved stenting might clearly different for types layers. In this study, a nonlinear finite element simulation was employed investigate effect composition (calcified, cellular, hypocellular) on (intima, media, adventitia) implantation balloon...

Coronary artery disease is the common form of cardiovascular diseases and known to be main reason deaths in world. Fluid-Structure Interaction (FSI) simulations can employed assess interactions artery/plaque blood provide a more precise anticipation for rupture arterial tissue layers plaque tissues inside an atherosclerotic artery. To date, computational FSI has been considered as one-layer structure. However, single layer assumption might have deeply bounded results and, consequently,...

ABSTRACT Poly(vinyl alcohol) sponges (P‐sponges) have been used as a potential implant material for the replacement and repair of soft tissues, including cartilage, liver, kidney. However, application P‐sponges tissue materials is almost entirely bounded because lack sufficient mechanical properties. In this study, we characterized properties fabricated poly(vinyl sponge (P‐sponge) under series longitudinal circumferential uniaxial loadings. The nonlinear behavior P‐sponge was also...

Coronary artery disease is responsible for almost 30% of all deaths worldwide. The saphenous vein and umbilical (UV) are the most common veins using treatment as a coronary bypass graft (CABG). mechanical properties UV belonging to its long-term patency CABG very important. However, there lack knowledge on linear elastic nonlinear hyperelastic UV. In this study, three stress definitions (second Piola–Kichhoff stress, engineering true stress) four strain (Almansi–Hamel strain, Green–St Venant...
