Aluminum and Sulphate Removal by a Highly Al-Resistant Dissimilatory Sulphate-R...
Martins, M; Taborda, R; Silva, G; Assunção, A; Matos, AP; Costa, MCA highly Al-resistant dissimilatory sulphatereducing bacteria community was isolated from sludge of the wetland of Urgeiriça mine (community W). This community showed excellent sulphate removal at the presence of Al3+. After 27 days of incubation, 73,86 and 81% of sulphate was removed in the presence of 0.48, 0.90 and 1.30 mM of Al3+, respectively. Moreover,Al3+ was simultaneously removed: 55,85 and 78% of meta...
Posterior reversible encephalopathy syndrome and anti-angiogenic agents: a case...
Silva, F; Pêgo, P; Vendrell, MC; Farias, MJ; Timóteo, A; Costa, MC; Cravo, I; Gomes, FPosterior reversible encephalopathy syndrome is an increasingly recognised clinico-radiological entity, associated with several medical conditions (such as systemic arterial hypertension) and characterised by seizures, altered mental status, headaches, and visual symptoms. Magnetic resonance imaging is a key component in this diagnosis, with hyperintense foci in T2-weighted images, corresponding to vasogenic oe...
Motor uncoordination and neuropathology in a transgenic mouse model of Machado-...
Silva-Fernandes, A; Costa, MC; Duarte-Silva, S; Oliveira, P; Botelho, C; Martins, L; Mariz, J; Ferreira, T; Ribeiro, F; Correia-Neves, M; Costa, CMachado-Joseph disease (MJD) is a late-onset neurodegenerative disorder caused by a polyglutamine (polyQ) expansion in the ataxin-3 protein. We generated two transgenic mouse lineages expressing the expanded human ataxin-3 under the control of the CMV promoter: CMVMJD83 and CMVMJD94, carrying Q83 and Q94 stretches, respectively. Behavioral analysis revealed that the CMVMJD94 transgenic mice developed motor unco...
Nonsense mutation in TITF1 in a Portuguese family with benign hereditary chorea
Costa, MC; Costa, C; Silva, A; Evangelista, P; Santos, L; Ferro, A; Sequeiros, J; Maciel, PBenign hereditary chorea (BHC) is an autosomaldominant disorder of early onset characterized by a slowly progressing or nonprogressing chorea, without cognitive decline or other progressive neurologic dysfunction, but also by the existence of heterogeneity of the clinical presentation within and among families. The genetic cause of BHC is the presence of either point mutations or deletions in the thyroid transc...
Molecular diagnosis of Huntington disease in Portugal: implications for genetic...
Costa, MC; Magalhães, P; Ferreirinha, F; Guimarães, L; Januário, C; Gaspar, I; Loureiro, L; Vale, J; Garrett, C; Regateiro, FJ; Magalhães, M; Sousa, AHuntington disease (HD) is a neurodegenerative, autosomal dominant disorder of late-onset, caused by the expansion of a CAG repeat in the coding region of the gene. Ours is the reference laboratory for genetic testing in HD, in Portugal, since 1998; 90.1% of all 158 families known were identified for the first time, including patients with unusual presentation or without family history. A total of 338 genetic t...
