Sementes de vida: Crenças e rituais na jornada da maternidade
Vale, Ana Catarina; Assis, Cátia; Quintão, Cláudia; Mariana, MartaA cultura desempenha um papel relevante quando se trata da transição da mulher para a experiência da maternidade. Muitos fatores podem contribuir para a experiência da gravidez, parto e pós-parto, incluindo a segurança percecionada, a participação no parto, a experiência da dor, o apoio familiar, os cuidados materno-obstétricos, a experiência de partos anteriores, a analgesia intraparto, o conhecimento da mulhe...
Comparison of zinc oxide nanoparticle integration into non-woven fabrics using ...
Ferreira, Tânia; Vale, Ana Catarina; Pinto, Alexandra C.; Costa, Rita V.; Pais, Vânia; Sousa, Diana; Gomes, Fernanda Isabel Antunes; Pinto, GraçaThe development of advanced facemasks stands out as a paramount priority in enhancing healthcare preparedness. In this work, different polypropylene non-woven fabrics (NWF) were characterised regarding their structural, physicochemical and comfort-related properties. The selected NWF for the intermediate layer was functionalised with zinc oxide nanoparticles (ZnO NPs) 0.3 and 1.2wt% using three different method...
Green pathway for processing non-mulberry antheraea pernyi silk fibroin/chitin-...
Silva, Simone S.; Gomes, J. M.; Vale, Ana Catarina; Lu, Shenzhou; Reis, R. L.; Kundu, Subhas CSilk protein fibroin (SF)-based matrices from non-mulberry, and mulberry silkworms are used for different applications in regenerative medicine. Silk fiber spun by the wild non-mulberry silkworm Antheraea pernyi (Ap) is also a promising biomedical material, due to the presence of the inherent tripeptide sequence of Arginine-Glycine-Aspartic acid (RGD) on the protein fibroin sequences. However, SF derived from t...
Novel antibacterial and bioactive silicate glass nanoparticles for biomedical a...
Vale, Ana Catarina; Carvalho, Ana Luísa; Barbosa, Ana Margarida Martins; Torrado, Egídio; Mano, J. F.; Alves, N. M.In this work, the authors propose a new quick sol–gel procedure for bioglass nanoparticles production containing 10% mol of silver (AgBGs). These new AgBGs are characterized by Zeta potential analysis, scanning electron microscopy with X-ray microanalysis (SEM/EDS), X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and microbiological tests to confirm their bioactive and antibacter...
Arthritis induces early bone high turnover, structural degradation and mechanic...
Vidal, Bruno; Cascão, Rita; Vale, Ana Catarina; Cavaleiro, Inês; Vaz, Maria Fátima; Brito, José Américo Almeida; Canhão, Helena; Fonseca, João EuricoBACKGROUND: We have previously found in the chronic SKG mouse model of arthritis that long standing (5 and 8 months) inflammation directly leads to high collagen bone turnover, disorganization of the collagen network, disturbed bone microstructure and degradation of bone biomechanical properties. The main goal of the present work was to study the effects of the first days of the inflammatory process on the micr...
