A bionic multilayer vascular model that conforms to the real vascular morphology and mechanical properties of arterial vessels can help surgeons familiarise themselves with the mechanical properties of blood vessels in preoperative simulations and thus avoid the risk of intraoperative vascular puncture. In this paper, porcine abdominal aortic vessels were used as a biological model to evaluate its mechanical properties by T-peel test, uniaxial tensile test and puncture force test. The results showed that the average delamination force between the intima and media of the vessels was 1.11 N. The radial tensile strength of the vessels was greater than the axial tensile strength and the elongation at the break of the media increased after peeling the intima. A multilayer vascular model manufacturing method was developed, and the structural integrity was improved using an intima–media nesting method.

The idea is to propose a method where polyvinylsiloxane impressions, as used in many dental practices, can be combined with surface texture analysis for a rapid, non-invasive, and inexpensive approach to detect and monitor the progression of tooth wear at fine scales over short durations and help determine causal agents of dental tissue loss. We employed both in vitro experimentation and in vivo analysis for abrasion and erosion of enamel and dentin surfaces. Three-dimensional point clouds of impression surfaces were generated using a scanning confocal profiler and analysed using both standard ISO and scale-sensitive fractal analysis approaches. The authors’ results indicate that texture attributes distinguish sound, abraded, and eroded surfaces. Furthermore, microwear textures can parse erosive tooth wear by the causal pH level and duration of exposure. These and other related studies indicate that dental microwear texture analysis holds potential for determining the aetiology of pathological tooth wear and for the clinical assessment and monitoring of dental patients at risk for excessive dental tissue loss at fine scales over short intervals.</p>","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.12089","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143423871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary causes of enamel degradation were assessed through a combinatorial investigation probing the impact of carbonation, acid type, acid concentration, and saliva. The average surface roughness of HA discs was determined after successive demineralisation steps. The heterogeneity of the decay process was assessed using multiple spatial replicates per sample. To aid in the interpretation of the HA decay profiles, pH and titratable acidity of each beverage were also measured. The authors find that, in comparison to a reference sample of Coca-Cola®, kombucha is equally erosive after prolonged exposure while hard seltzer results in relatively minor surface damage.

However, the relationship between friction properties and these effects remains unclear. Traditional measurement methods often fail to replicate real-life conditions, thereby highlighting the need for more effective apparatus. In this study, the authors developed an optimised pendulum apparatus integrated with an inclinometer to enhance the measurement of CL friction coefficients, thereby improving its precision and relevance to clinical settings. This new design allows for faster and easier calculation of the friction coefficient based on the amplitude decay per libration cycle, surpassing the accuracy of previous video-based methods. The pendulum's hemisphere component was made from ethylene–propylene–diene monomer rubber (EPDM) 30, which has an elastic modulus similar to that of a human eyeball, creating a measurement environment that closely mimics real-world usage. The authors optimised the apparatus by evaluating the effects of hemisphere stiffness and saline volume on the friction coefficient. Measurements of multiple lenses recorded by the authors, particularly Lens A, made of narafilcon A, revealed significant consistency across different hemisphere materials with an optimal saline volume of 150 μL yielding a friction coefficient of 0.026 ± 0.003. No statistically significant differences in the friction coefficients were found across variations in the lens base curve, diameter, centre thickness, or power. This improved apparatus demonstrates the capability of effectively measuring friction coefficients under conditions that simulate clinical usage, providing rapid and reliable results. The findings validate the apparatus and suggest its potential for broader applications in assessing CL properties, thereby facilitating future research on the material characteristics and safety of various CLs, including decorative lenses.</p>","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"10 4","pages":"167-175"},"PeriodicalIF":1.8,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.12086","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
