- Effect of oxygen carriers in microbial and plant cell cultures.Publication . Raposo, Sara; Santos, M.Dissolved oxygen concentration is one of the most limiting factors in aerobic cultures, due to the poor solubility of oxygen in aqueous media. In many processes, the microorganisms growth and production can be affected as a result of insufficient oxygen supply to the broths [1, 2]. To increase oxygen solubility, some methods can be used, such as the increment of aeration or agitation rates or decrease of the solution temperature.
- Prevalence and clinical characteristics of late Onset Axial Spondyloarthritis: Results from a multicentre nationwide studyPublication . Rocha, Margarida Lucas; Torres, R.; Ramiro, S.; Castro, A. M.; Neves, A.; Martins, A.; Chícharo, A. T.; Mendes, B.; Matos, C. O.; Soares, C.; Oliveira, C. P.; Parente, H.; Gomes, J. A. M.; Luís, M.; Santos, M.; Couto, M.; Bernardes, M.; Valente, P.; Costa, R.; Sousa, S.; Branco, J.; Pimentel-Santos, F.; Sepriano, A.Axial spondyloarthritis (axSpA) typically starts before the fourth decade oflife. Consistent with that, the Assessment of SpondyloArthritis international Society (ASAS)classification criteria for axSpA should be applied only in patients with chronic back pain startingbefore 45 years of age. It has, however, been suggested that axSpA can sometimes start later in lifewith a distinctive phenotype, the so-called ‘late onset axSpA’ (lo-axSpA). There is, nevertheless, onlylimited data in support of the existence of such phenotype. We aimed to evaluate the occurrence oflo-axSpA and if these patients differ from those with early onset axSpA (eo-axSpA).
