Revision Arthroplasty in Vancouver B1 Periprosthetic Hip Fractures
Pereira, João C.; Moreira, André; Costa, André; Correia, Guilherme; Tinoco, João B.; Varanda, Pedro; Rodrigues, Eurico B.Introduction: Periprosthetic hip fractures (PHF) represent an important complication after hip arthroplasty. The management of Vancouver B1 fractures remains elusive. While most stems may present radiographically as stable, stem fixation may in fact be compromised. Choosing plate osteosynthesis as a treatment in this type of fractures, trusting radiographic studies alone may lead to implant failure. Methods: We...
Enhancing automotive products with TinyML and MEMS sensors: a preliminary approach
Sousa, Lídia; Silva, Rui; Peixoto, Hugo; Melo-Pinto, Pedro; Costa, André; Melo, César; Delgado, Pedro; Fukuda, Vitor; Machado, José ManuelThe Tiny Machine Learning (TinyML) research field has seen exponential growth in recent years, mostly due to advances in the usage of IoT devices and microcontrollers. Despite major challenges related to hardware constraints, TinyML has been expanding the scope of applications in several domains, with the automotive industry taking special interest in these models for their potential to enhance existing Advance...
Peptide-keratin interactions for enhanced hair properties
Carvalho, José; Rodrigues, Ana Rita O.; Ferreira, Tiago; Gomes, Vânia; Pereira, Francisco; Martins, Cátia D. F.; Martins, MadalenaSummary Fusion peptides inspired by natural elastomeric proteins are fused to a keratin peptide (KP) and tested on damaged hair. Here, we report thermal and mechanical tests conducted on treated damaged hair in conjunction with the peptides physicochemical properties, resulting in a statistical multiparametric analysis. Among the parameters, the Youngs modulus and the keratin helix denaturation temperature show...
Can a Plegic Leg Move Itself?
Borges, Catarina; Costa, André; Velon, Ana Graça; Mendes, MichelThe spinal cord is responsible for several types of involuntary movements, from segmental spinal myoclonus to stepping automated movements generated by spinal central pattern generators (CPG). We present the case of a 47-year-old inpatient woman admitted for suspected spondylodiscitis. Immediate neurologic evaluation was requested in day 2 due to involuntary movements. The neurological examination revealed para...
Bilateral Neurolymphomatosis of the Cerebellopontine Angle
Azoia, Carolina Q.; Marques, Ana João; Costa, André; Taipa, Ricardo; Rocha, LuísTumours of the cerebellopontine angle and internal auditory canal are frequent, typically vestibular schwannomas (only rarely bilateral) and meningiomas. We describe the case of a 76-year-old man who presented with persistent peripheral facial paralysis, which proved to be secondary to a process of bilateral primary neurolymphomatosis of the facial and vestibulocochlear cranial nerves, caused by sequential invo...
Setting performance indicators for coastal marine protected areas: An expert-ba...
Cardoso-Andrade, Mariana; Queiroga, Henrique; Rangel, M; Sousa, Inês; Belackova, Adela; Bentes, Luis; Oliveira, Frederico; Monteiro, PedroMarine Protected Areas (MPAs) require effective indicators to assess their performance, in compliance with the goals of relevant national and international commitments. Achieving and prioritizing shortlists of multidisciplinary indicators demands a significant effort from specialists to depict the multiple conservation and socioeconomic interests, and the large complexity of natural systems. The present paper d...
Therapeutic textiles functionalized with keratin-based particles encapsulating ...
Costa, André; Luís, Salomé; Noro, Jennifer Martins; Silva, Sónia Carina; Silva, C.; Ribeiro, ArturOnychomycosis is the most common nail fungal infection worldwide. There are several therapy options available for onychomycosis, such as oral antifungals, topicals, and physical treatments. Terbinafine is in the frontline for the treatment of onychomycosis; however, several adverse effects are associated to its oral administration. In this work, innovative keratin-based carriers encapsulating terbinafine were d...
Measuring in-situ X-ray scattering of natural rubber biaxial deformation: A new...
Silva, Daniel P. da; Lamolinara, Barbara; Costa, André; Gameiro, Fábio; Pascoal-Faria, Paula; Mateus, Artur; Martinez, Juan Carlos; Phinyocheep, PraneeUnderstanding biaxial deformation is essential for a more realistic evaluation of rubber elasticity compared to the more usual uniaxial deformation. To study crystallisation occurring during biaxial deformation of natural rubber films, a new simple equipment has been designed and assembled. The equipment, mounted in the beamline of ALBA synchrotron light source facility, allowed the in-situ measurement of X-ray...
