This study aims to present an easily scalable, cost-efficient process of dECM extraction from porcine meniscus, dedicated bioink preparation and 3D bioprinting. Due its cartilage like structure mechanical robustness, the meniscus is exceptionally demanding tissue for decellularisation ECM. Its processing poses a great difficulty renders methods previously developed soft tissues useless. A process, combining homogenisation, hydrolysis, supercritical CO2 (scCO2) lyophilisation, was meet this...
Piezoelectric materials such as PVDF and its copolymers have been widely studied in different areas with promising applications, haptic feedback actuators or deformation sensors for aided-mobility scenarios. To develop PVDF-based solutions, protocols are reported the literature; however, a toxic harmful solvent is commonly used (dymethilformamide (DMF)). In present study, non-toxic (dymethilsulfoxide (DMSO)) to dissolve powder, while specific ionic liquid (IL), [PMIM][TFSI], enhance...
In recent years, several efforts have been made to develop quick and low cost bacterial identification methods. Genotypic methods, despite their accuracy, are laborious time consuming, leaving spectroscopic methods as a potential alternative. Mass infrared spectroscopy among the most reconnoitered techniques for this purpose, with Raman having practically unexplored. Some species of genus Acinetobacter recognized etiological agents nosocomial infections associated high rates mortality...
The aim of this study is to analyse the mechanical properties agarose, which can be used as a phantom for breast tissues. In general, tissue mimicking materials may achieve better understanding structure and tissues organs; work shares these objectives. surrogate with realistic behaviour biomechanical applications. To validate agarose suitable tissues, indentation tests were performed in homogeneous, rectangular blocks. Blocks different concentrations moulded tested. An estimation material...
Low urinary tract dysfunctions and symptoms (LUTS) affect both men woman, with the incidence increasing age. Among LUTS, incontinence (UI) is a common dysfunction, characterised by involuntary loss of urine. These medical conditions become debilitating, severe impact on patients’ routines overall well-being. To mitigate LUTS-associated symptoms, mechanical behaviour normal LUTS-affected urethrae can be an important tool. The current work approaches porcine urethra as replacement candidate...
Abstract Tissue engineering uses cells and biomaterials to develop bioartificial tissue substitutes for different purposes. For example, although several skin models have been developed pharmaceutical cosmetic research wound healing, there are few studies on 3D cultures of keratinocytes in printed scaffolds. So, this work aimed a 3D‐printed hydrogel scaffold promote human keratinocyte growth. Mesh scaffolds were using an extrusion‐based method with 20% gelatin/5% alginate hydrogel, where...
Objectives: Angiotensin-converting enzymes’ (ACEs) relationship with blood pressure (BP) during childhood has not been clearly established. We aimed to compare ACE and ACE2 activities between BMI groups in a sample of prepubertal children, characterize the association these BP. Methods: Cross-sectional study 313 children aged 8–9 years old, included birth cohort Generation XXI (Portugal). Anthropometric measurements 24-h ambulatory BP monitoring were performed. quantified by fluorometric...
