1. Glycosaminoglycan-based scaffolds for bone repair

Author

Monteiro, Beatriz, Ortega, Ilida, Hatton, Paul, Cool, Simon, and Teo, Peili

Abstract

Adding complexity to biomaterials by mimicking extracellular matrix-like components as well as biomechanical cues is a powerful strategy for enhancing the performance of implantable materials for orthopaedic purposes. In recent years, bone morphogenic protein 2 (BMP-2), a potent osteoinductive factor has gained popularity within the orthopaedic community to stimulate bone regeneration. Despite showing strong osteoestimulatory effects, the short half-life of BMP-2 requires supraphysiological doses to achieve efficacious clinical outcomes which have been repeatedly associated with life-threatening side effects. Glycosaminoglycans (GAGs) of the heparin/heparan sulphate (HS) are key components of the extracellular matrix that bind, stabilise and protect factors such BMP-2 from degradation. Despite being available at a clinical grade, the anticoagulant property of heparin coupled with its ability to bind non-selectively to a wide range of stimulatory and inhibitory osteogenic factors is driving strategies to generate heparin structures that overcome these limitations. The actions of heparin/HS GAGs are dependent on their sulphation pattern and overall chain length. Recent findings from our group suggest that heparin fragments of 12 saccharides in length (dp12) optimally bind and stabilise BMP-2 to enhance its osteogenic effects. This suggests a path to increasing the selectivity of heparin for BMP-2 through a sizing strategy to reduce off-target effects. Therefore, this thesis aims to develop heparin-functionalised scaffolds for bone repair. Initially, we have explored adding micropatterns into electrospinning scaffolds or biomaterial biofunctionalisation (i.e., heparin) for increased scaffolds complexity. In search of a more sophisticated and reliable functionalisation method, bioactive copolymers containing nitrous acid generated heparin oligosaccharides were synthetised by ring-opening metathesis polymerisation (ROMP) to sustain BMP-2 signals over a prolonged period and manufactured into electrospinning scaffolds. Bioactive oligosaccharides F6 (dp10), F7 (dp12) and F8 (dp14) were successfully isolated from nitrous acid digested mixtures by size exclusion chromatography (SEC). Data obtained from BMP-2 response C2C12 cells suggested that heparin oligosaccharides have the ability to enhance BMP-2-mediated osteogenic responses determined by quantitative polymerase chain reaction (qPCR) of osteogenic genes, alkaline phosphatase (ALP) assay, mineralisation assays and Smad 1/5/9 phosphorylation assays. Nitrous acid generated oligosaccharides presented low anti-Factor Xa in comparison with native heparin and retained dose and chain length-dependent bioactive properties as a cheap alternative to enzymatic depolymerisation. Bioactive oligosaccharides were then used to synthesise bioactive copolymers for bone repair. ROMP-derived bioactive copolymers were synthesised using polycaprolactone (PCL) macromonomers and oligosaccharide macromonomers with high conversion. The final copolymers presented a ~3-3.5 wt.% incorporation of oligosaccharide macromonomer into the final copolymer. The structural variability of bioactive electrospinning scaffolds was characterised in terms of fibre diameter, hydrophobicity, stiffness and thickness. In conclusion, the presented bioactive copolymers are a relevant platform for the design of advanced bone repair scaffolds able to tackle interdisciplinary tissue engineering challenges.

Abstract

Hybrid nanocomposites have emerged as a groundbreaking class of materials in the aerospace industry, offering exceptional mechanical, thermal, and functional properties. These materials, composed of a combination of metallic matrices (based on aluminum, magnesium, or titanium) reinforced with a mixture of nanoscale particles, such as carbon nanotubes (CNTs), graphene, and ceramic nanoparticles (SiC, Al2O3), provide a unique balance of high strength, low weight, and enhanced durability. Recent advances in developing these nanocomposites have focused on optimizing the dispersion and integration of nanoparticles within the matrix to achieve superior material performance. Innovative fabrication techniques have ensured uniform distribution and strong bonding between the matrix and the reinforcements, including advanced powder metallurgy, stir casting, in situ chemical vapor deposition (CVD), and additive manufacturing. These methods have enabled the production of hybrid nanocomposites with improved mechanical properties, such as increased tensile strength, fracture toughness, wear resistance, and enhanced thermal stability and electrical conductivity. Despite these advancements, challenges remain in preventing nanoparticle agglomeration due to the high surface energy and van der Walls forces and ensuring consistent quality and repeatability in large-scale production. Addressing these issues is critical for fully leveraging the potential of hybrid nanocomposites in aerospace applications, where materials are subjected to extreme conditions and rigorous performance standards. Ongoing research is focused on developing novel processing techniques and understanding the underlying mechanisms that govern the behavior of these materials under various operational conditions. This review highlights the recent progress in the design, fabrication, and application of hybrid nanocomposites for aerospace applications. It underscores their potential to revolutionize the industry by providing materials that meet the demanding requirements for lightweight, high-strength, and multifunctional components.

Abstract

Aluminum-based hybrid nanocomposites, namely the Al6061 alloy, have gained prominence in the scientific community due to their unique properties, such as high strength, low density, and good corrosion resistance. The production of these nanocomposites involves incorporating reinforcing nanoparticles into the matrix to improve its mechanical and thermal properties. The Al6061 hybrid nanocomposites were manufactured by conventional powder metallurgy (cold pressing and sintering). Ceramic silicon carbide (SiC) nanoparticles and carbon nanotubes (CNTs) were used as reinforcements. The nanocomposites were produced using different reinforcement amounts (0.50, 0.75, 1.00, and 1.50 wt.%) and sintered from 540 to 620 °C for 120 min. The characterization of the Al6061 hybrid nanocomposites involved the analysis of their mechanical properties, such as hardness and tensile strength, as well as their micro- and nanometric structures. Techniques such as optical microscopy (OM) and scanning electron microscopy (SEM) with electron backscatter diffraction (EBSD) were used to study the distribution of nanoparticles, the grain size of the microstructure, and the presence of defects in the matrix. The microstructural evaluation revealed significant grain refinement and greater homogeneity in the hybrid nanocomposites reinforced with 0.75 wt.% of SiC and CNTs, resulting in better mechanical performance. Tensile tests showed that the Al6061/CNT/SiC hybrid composite had the highest tensile strength of 104 MPa, compared to 63 MPa for the unreinforced Al6061 matrix. The results showed that adding 0.75% SiC nanoparticles and CNTs can significantly improve the properties of Al6061 (65% in the tensile strength). However, some nanoparticle agglomeration remains one of the challenges in manufacturing these nanocomposites; therefore, the expected increase in mechanical properties is not observed.

Abstract

This study investigates the impact of multi-walled carbon nanotubes (MWCNTs) on the microstructure and mechanical properties of Al6061 nanocomposites. The MWCNTs were uniformly dispersed in the aluminum alloy matrix using ultrasonication following cold pressing and sintering in a vacuum. The effect of the sintered temperature on the microstructure and mechanical properties of the nanocomposites was evaluated. The addition of MWCNTs resulted in grain refinement, with the nanocomposites exhibiting smaller and more uniformly distributed grains than the pure Al6061 matrix, particularly at lower sintering temperatures of 580 and 600 °C. The nanocomposites also demonstrated an increase in hardness, with peak values observed at 580 °C, primarily due to the effective dispersion of MWCNTs, which restrict dislocation movement and reinforce grain boundaries. While higher sintering temperatures led to significant grain growth and less uniform hardness distribution, lower temperatures favored finer grain structures and more homogeneous hardness profiles. The results suggest that the optimal sintering temperature for achieving the best balance between microstructure and mechanical properties is 580 °C. However, the study also highlights the need for optimized dispersion techniques to achieve a more uniform distribution of MWCNTs. [ABSTRACT FROM AUTHOR]

22. 2024 ISFM and AAFP consensus guidelines on the long-term use of NSAIDs in cats.

Author

Taylor, Samantha, Gruen, Margaret, KuKanich, Kate, X Lascelles, B Duncan, Monteiro, Beatriz P, Sampietro, Llibertat Real, Robertson, Sheilah, and Steagall, Paulo V

Abstract

Practical relevance: Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used and are effective for the management of pain in cats. These Guidelines will support veterinarians in decision-making around prescribing NSAIDs in situations of chronic pain, to minimise adverse effects and optimise pain management. Information is provided on mechanism of action, indications for use, screening prior to prescription, use in the presence of comorbidities, monitoring of efficacy, and avoidance and management of adverse effects. Clinical challenges: The cat's unique metabolism should be considered when prescribing any medications, including NSAIDs. Chronic pain may be challenging to detect in this species and comorbidities, particularly chronic kidney disease, are common in senior cats. Management of chronic pain may be complicated by prescription of other drugs with the potential for interactions with NSAIDs. Evidence base: These Guidelines have been created by a panel of experts brought together by the International Society of Feline Medicine (ISFM) and American Association of Feline Practitioners (AAFP). Information is based on the available literature, expert opinion and the panel members' experience. [ABSTRACT FROM AUTHOR]

Abstract

The processing and characterizing of bonding Ti6Al4V to Al2O3 brazed joints using interlayer thin films was investigated. The brazing was conducted in a tubular furnace with an argon flux at 980 °C for 30 min. The brazing fillers consisted of different combinations of thin Ag/Cu and Ti films with variable thicknesses. The joint interface analysis involved using digital microscopy (DM) and optical microscopy (OM). Microstructural characterization and chemical composition were performed via scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). Mechanical properties were assessed through microhardness and shear strength tests. Brazing successfully produced interfaces with a combination of titanium films and Ag/Cu as brazing filler. The results revealed that the interface mainly comprises Ti2Cu, TiCu2Al, α-Ti, and Ti2(Cu,Ag). Some segregation of (Ag) was observed at the interfaces, but a decrease in its amount was observed when compared to joints produced using Ag/Cu fillers. The thickness of the titanium film in the brazing filler strongly influenced the integrity of the joints. The amount of (Ag) at the interface diminished as the Ti film's thickness decreased, leading to an improvement in the mechanical properties of the joints. Using a combination of Ag/Cu and Ti thin films revealed a potential approach to reduce the segregation of soft phases at interfaces, promoting a significant improvement in joining metal to ceramic materials.

Cheng, Alice J, Malo, Annie, Garbin, Marta, Monteiro, Beatriz P, and Steagall, Paulo V

Abstract

Objectives: The aim of the present study was to investigate the construct validity, responsiveness and reliability of the Feline Grimace Scale (FGS) in kittens. Methods: A total of 36 healthy female kittens (aged 10 weeks to 6 months) were included in a prospective, randomized, blinded study. Video recordings of all kittens were made before and 1 and 2 h after ovariohysterectomy using an opioid-free injectable anesthetic protocol with or without multimodal analgesia. Additional recordings were taken before and 1 h after administration of rescue analgesia (buprenorphine 0.02 mg/kg IM) to painful kittens. Screenshots of facial images were collected from the video recordings for FGS scoring. Four observers blinded to treatment groups and time points scored 111 randomized images twice with a 5-week interval using the FGS. Five action units (AUs) were scored (ear position, orbital tightening, muzzle tension, whiskers position and head position; 0–2 each). Construct validity, responsiveness, and inter- and intra-rater reliability were evaluated using linear models with Benjamini–Hochberg correction, Wilcoxon signed-rank test and single intraclass correlation coefficients (ICCsingle), respectively (P <0.05). Results: FGS total ratio scores were higher at 1 and 2 h after ovariohysterectomy (median [interquartile range, IQR]: 0.30 [0.20–0.40] and 0.30 [0.20–0.40], respectively) than at baseline (median [IQR]: 0.10 [0.00–0.30]) (P <0.001). FGS total ratio scores were lower after the administration of rescue analgesia (median [IQR] before and after rescue analgesia) 0.40 [0.20–0.50] and 0.20 [0.10–0.38], respectively (P <0.001). Inter-rater ICCsingle was 0.68 for the FGS total ratio scores and 0.35–0.70 for all AUs considered individually. Intra-rater ICCsingle was 0.77–0.91 for the FGS total ratio scores and 0.55–1.00 for all AUs considered individually. Conclusions and relevance: The FGS is a valid and responsive acute pain-scoring instrument with moderate inter-rater reliability and good to excellent intra-rater reliability in kittens.

Abstract

Relatório de Estágio do Mestrado em Estudos Artísticos apresentado à Faculdade de Letras A Indústria Musical na Era DigitalEste relatório de estágio resulta de um estágio curricular realizado na entidade cultural residente no coração da baixa de Coimbra, o Salão Brazil. Sala de espetáculos usada pela associação sem fins lucrativos Jazz ao Centro Clube (JACC). Este estágio realizou-se num espaço de 6 meses — entre 4 de outubro de 2021 a 4 de abril de 2022.O estágio curricular teve como orientadores José Miguel Pereira, Presidente do Jazz ao Centro Clube e programador artístico do Salão Brazil, e uma coordenação diária da Vice-Presidente e produtora do espaço, Adriana Ávila. A realização deste relatório e todo o acompanhamento académico durante a realização do Estágio foi feito pelo Professor Doutor José Oliveira Martins, com adição de coorientação da Professora Doutora Leonor Losa.Na parte inicial deste relatório, visa-se debater o conceito de indústrias culturais e musicais, a partir dos conceitos estruturados por vários académicos como Adorno (1991); Adorno e Horkheimer (1997); Hesmondhalgh (2013); Negus (1992); Wikström (2005 e 2009) — obras fulcrais para o desenvolvimento teórico das conclusões de estágio curricular.Segue-se com um enquadramento da história e das estratégias culturais do Jazz ao Centro Clube e do Salão Brazil — onde se entende associativismo, como as principais atividades da associação e a programação inserida neste espaço cultural.Prossegue-se com um “Diário de Bordo”, descrevendo as atividades que fui realizando, com destaque para as atividades que considerei mais importantes deste estágio. Descreve-se detalhadamente um dia de trabalho no Salão Brazil, tanto em horário de escritório como em horário de concerto. Procura-se conhecer mais afincadamente a JACC Records e consequentemente as estratégias de marketing usadas pela entidade culturalProcura-se de seguida, ter uma visão focada sobre o consumo da música, e como esta é vivenciada como a própria estética de quem a ouve, incutindo as novas ferramentas da indústria e fazendo uma análise da mesma, nos parâmetros globais e nacionais.Termina-se com um estudo entre estas duas vertentes: (a) um estudo da conjunção de todas as políticas e vertentes culturais que promovem a permanência do Salão Brazil como elemento crucial à expansão cultural na cidade de Coimbra e (b) uma reflexão sobre as várias transformações recentes que se deram na indústria musical e na nova comercialização da forma artística que é a música, e como podemos presenciar este novo consumo neste tipo de espaço cultural. The Music Industry in the Digital AgeThis internship report is the result of a curricular internship carried out in Salão Brazil. a cultural organization in the heart of downtown Coimbra. Whose concert hall is used by the non-profit association Jazz ao Centro Clube (JACC). This internship took place over the period of 6 months from October 4, 2021 to April 4, 2022.This internship was guided by José Miguel Pereira, President of Jazz at Centro Clube and artistic programmer of Salão Brazil, with regular supervision by the Vice-President and producer of the space, Adriana Ávila. The preparation of this report and all the academic monitoring during the Internship was carried out under the guidance of Professor’s José Oliveira Martins and Professor Leonor Losa.In the initial part of this report, my aim is to understand the concept of cultural and musical industries, using as a reference some concepts proposed by several academics, such as Adorno (1991); Adorno and Horkheimer (1997); Hesmondhalgh (2013); Negus (1992) and Wikström (2005 and 2009) — key works to form the theoretical framework of this curricular internship’s conclusions.We continue with an account of the history and cultural strategies of Jazz ao Centro and Salão Brasil — associativism is understood as one of the main activities of the association, JACC Records as well as the programming that is developed in this cultural space.This report follows with the framework of the history and cultural defenses of Jazz ao Centro and Salão Brasil — associativism is understood, as well as the main activities of the association and the programming inserted in this cultural space.The report follows with a logbook, explaining all the main activities I completed throughout the internship. The working day at Salão Brazil is detailed, both during office hours and during concert hours. I attempt to know more closely the working habits of JACC Records in order to better understand the marketing strategies used by the cultural entity.I then turn my view on the consumption of music, and how this is experienced attending to the aesthetics of those who listen to it, experimenting with new tools which attend to the analysis of the industry, in global and national parameters.Finally, I attend to two aspects: (a) a study of the conjunction of the policies and cultural aspects that promote the permanence of Salão Brazil as a crucial element for the cultural expansion in the city of Coimbra and (b) the music industry and the new distribution of music, and how we can witness music consumption in this type of cultural space.
