Gellan gum: A new biomaterial for cartilage tissue engineering applications
João T. Oliveira,Luis F. Martins,Ricardo Picciochi,P. B. Malafaya,Rui A. Sousa,Nuno M. Neves,João F. Mano,Rui L. Reis +7 more
TL;DR: The obtained data supports the claim that this new biomaterial has the potential to serve as a cell support in the field of cartilage regeneration.
Journal ArticleDOI
Time-varying cointegration
TL;DR: In this paper, a time-varying vector error correction model is proposed, in which the cointegrating relationship varies smoothly over time, and a likelihood ratio test for time-invariant cointegration is defined and its asymptotic chi-square distribution is derived.
Journal ArticleDOI
An empirical analysis of the influence of macroeconomic determinants on World tourism demand
TL;DR: In this article, the relationship between macroeconomic variables and tourism demand is investigated in an unbalanced panel of 218 countries over the period 1995-2012, and the results show that an increase in the World's GDP per capita, a depreciation of the national currency and a decline of relative domestic prices do help boost tourism demand.
Journal ArticleDOI
Gellan gum injectable hydrogels for cartilage tissue engineering applications: in vitro studies and preliminary in vivo evaluation
João T. Oliveira,Tírcia C. Santos,Luis F. Martins,Ricardo Picciochi,Alexandra P. Marques,António G. Castro,Nuno M. Neves,João F. Mano,Rui L. Reis +8 more
TL;DR: The results demonstrate the adequacy of gellan gum hydrogels processed by simple methods for noninvasive injectable applications toward the formation of a functional cartilage tissue-engineered construct and originally report the preliminary response of a living organism to the subcutaneous implantation of the gllan gum Hydrogels.
Journal ArticleDOI
Injectable gellan gum hydrogels with autologous cells for the treatment of rabbit articular cartilage defects.
João T. Oliveira,Leandro S. Gardel,Leandro S. Gardel,Tommaso Rada,Luis F. Martins,Manuela E. Gomes,Rui L. Reis +6 more
TL;DR: Gellan gum hydrogels combined with autologous cells constitute a promising approach for the treatment of articular cartilage defects, and adipose derived cells may constitute a valid alternative to currently used articular chondrocytes.
