In order to delineate the spectrum and the relative abundance of beta-globin gene defects causing thalassaemia in the Portuguese population, a representative sample was analysed including 51 beta-thalassaemia carriers along with 26 patients representing different clinical phenotypes. Seven mutations were identified, four of which [codon 39 (C----T), 39%;(More)
Familial amyloid polyneuropathy (FAP), Portuguese type, is a late onset, high penetrance, autosomal dominant Mendelian disorder caused by a V30M substitution in the transthyretin (TTR) protein. A genetic diagnosis was developed using fluorescent single cell polymerase chain reaction (PCR) on lymphocytes from patients and controls. Ovarian stimulation and(More)
An autosomally transmitted hypochromic microcytic mild anaemia with elevated haemoglobin (Hb) A2 and globin chain imbalance has been observed in a three-generation family of Portuguese origin. Extensive DNA analysis of the beta-globin gene cluster, including the complete sequencing of the beta-globin gene and flanking regions, failed to reveal any genetic(More)
In the present study we conducted proteomic and pharmacological characterizations of the venom extracted from the Brazilian tarantula Acanthoscurria paulensis, and evaluated the cardiotoxicity of its two main fractions. The molecular masses of the venom components were identified by mass spectrometry (MALDI-TOF-MS) after chromatographic separation (HPLC).(More)
Neurodegenerative diseases are relentlessly progressive, severely impacting affected patients, families and society as a whole. Increased life expectancy has made these diseases more common worldwide. Unfortunately, available drugs have insufficient therapeutic effects on many subtypes of these intractable diseases, and adverse effects hamper continued(More)
To elucidate the origin and spread of the sickle cell trait into the Portuguese population, we examined nine polymorphic DNA markers within the beta globin gene cluster defining the haplotype. The population sample included 64 sickle-cell-gene-bearing individuals from defined Portuguese-speaking white, black, and Asian Indian populations. The nature and(More)
BACKGROUND The use of human recombinant erythropoietin (rHuEPO) in pregnant patients has been limited by the fear of eventual maternal and fetal repercussions (either direct or indirect). METHODS The authors present their experience with the use of rHuEPO during pregnancy, with two pregnant women with kidney transplants and in three others with chronic(More)
