AIM To assess in a subset of a nationally representative sample of Portuguese adolescents, the validity of Body Mass Index (BMI) based on self-reported weight and height. METHODS This study included 462 students in grades 6, 8 and 10 (mean age 14.0 +/- 1.9 years) from 12 public schools randomly selected from the list of schools which took part in the 2006(More)
Epilepsy comprises several syndromes, amongst the most common being mesial temporal lobe epilepsy with hippocampal sclerosis. Seizures in mesial temporal lobe epilepsy with hippocampal sclerosis are typically drug-resistant, and mesial temporal lobe epilepsy with hippocampal sclerosis is frequently associated with important co-morbidities, mandating the(More)
Amyloid fibrils were concentrated from the kidney, thyroid, and peripheral nerve of six patients with familial amyloidotic polyneuropathy (FAP). The fibril concentrates were solubilized in 6 M guanidine.HCl and fractionated on Sephadex G-100 columns. The elution profile of all FAP amyloid fibril concentrates revealed a protein of apparent Mr of 14,000,(More)
We report the biochemical and molecular characterization of two new transthyretin (TTR) variants in two Italian families with hereditary amyloidosis. Both families presented neuropathy and cardiomyopathy but they differ in other clinical features. These TTR variants were previously detected by isoelectric focusing (IEF); one is a neutral TTR variant and the(More)
Familial amyloidotic polyneuropathy (FAP) is an autosomal dominant genetic disease characterized by systemic accumulation of amyloid fibrils. A major component of FAP amyloid has been identified as variant transthyretin (TTR, also called prealbumin). In particular, a variant with the substitution 30Val----Met has been commonly found in FAP of various ethnic(More)
Systemic lupus erythematosus (SLE) is a prototypical autoimmune disease with strong genetic and environmental components. Previous studies have shown increased levels of several chemokines in active SLE. C-C chemokine receptor type 5 (CCR5) is involved in the recruitment of inflammatory cells into tissues, and mechanisms modulating CCR5 expression and(More)
The first Swedish case of familial amyloidotic polyneuropathy (FAP) was published in 1965. The same transthyretin (TTR met30) mutation as that seen in Japanese, Portuguese, and other populations was also found in Swedish FAP patients. More than 350 patients with clinical manifestations of FAP have been diagnosed in northern Sweden, most of them originating(More)
Amyloid fibril protein in patients with familial amyloidotic polyneuropathy is known to be chemically related to transthyretin (TTR), the plasma protein that is usually referred to as prealbumin. A genetically abnormal TTR may be involved in this disease. Studies were conducted on amyloid fibril protein (AFp) isolated from tissues of two Portuguese patients(More)
In summary, these studies have demonstrated the following: 1) plasma TTR levels are significantly decreased in Portuguese patients with FAP; 2) FAP-TTR is indistinguishable from normal TTR with regard to a wide range of physiochemical properties; 3) RBP levels and vitamin A transport appear to be normal in FAP patients; 4) an abnormal TTR with a methionine(More)
Interleukin 6 (IL-6) is a class-I helical cytokine with a broad spectrum of biological activities and a gene structure conserved throughout vertebrates, with five coding exons. IL-6 from European rabbits belonging to the subspecies Oryctolagus cuniculus cuniculus was previously shown to differ from other mammals by extending an additional 27 amino acids.(More)
