One cardinal feature of Huntington's disease (HD) is the degeneration of striatal neurons, whose survival greatly depends on the binding of cortical brain-derived neurotrophic factor (BDNF) with high-affinity (TrkB) and low-affinity neurotrophin receptors [p75 pan-neurotrophin receptor (p75(NTR))]. With a few exceptions, results obtained in HD mouse models(More)
In the adult brain, neurons require local cholesterol production, which is supplied by astrocytes through apoE-containing lipoproteins. In Huntington's disease (HD), such cholesterol biosynthesis in the brain is severely reduced. Here we show that this defect, occurring in astrocytes, is detrimental for HD neurons. Astrocytes bearing the huntingtin protein(More)
Reduced Brain-Derived Neurotrophic Factor (BDNF) levels have been described in a number of patho-physiological conditions, most notably, in Huntington's disease (HD), a progressive neurodegenerative disorder. Since BDNF is also produced in blood, we have undertaken the measurement of its peripheral levels in the attempt to identify a possible link with HD(More)
We describe a novel strategy for mRNA normalization in quantitative real-time PCR that is based on expressed Alu repeat amplification as a measure for the mRNA fraction. We show that expressed Alu repeat amplification is a fast, accurate normalization tool that can be successfully used for quantification of selected mRNA in the human transcriptome. This(More)
We have previously demonstrated that the transcription of neuronal repressor element-1/neuron-restrictive silencer element (RE1/NRSE)-regulated genes is reduced in the brain of subjects with Huntington's disease (HD) as a result of increased binding of the repressor element-1 silencing transcription factor/neuron-restrictive silencer factor (REST/NRSF) to(More)
The Authors present a clinical case of pseudo-thrombophlebitic syndrome caused by a cyst of the inner popliteal hamstrings. Pointing out anatomic characteristics of the area involved together with the physiopathology and etiology of the formation that fill the space of the inner popliteal hamstrings, in agreement with the observations reported in(More)
Background Abnormalities in brain cholesterol homeostasis have been reported in Huntington's disease (HD), an adult-onset neurodegenerative disorder caused by an expansion in the number of CAG repeats in the huntingtin (HTT) gene. However, the results have been contradictory with respect to whether cholesterol levels increase or decrease in HD models.(More)
Merkel cell tumor (MCT) is extremely rare, being discovered so far about 400 cases in literature. It is classified among neuroendocrine tumors. We report a case of MCT in the subclavicular region in a 93 years old woman. We confirm the efficacy of radiotherapy associated with octreotide, which these tumours express specific receptors for.
In the natural history of the breast cancer, the liver metastatic location represents a clear element of an advanced stage of the disease, because it is often accompanied to multiple locations in the same organ and/or in different organs and tissues. The finding into two years after the primary intervention, during the ordinary follow-up, of an insulated(More)
Gastrointestinal cancers are very scarce for the people under twenties. Such a rarity, as misguides diagnostic trend, is responsible, in the greater part of cases, of the lag in the recognizing these neoplasm and, consequently, reduces the expectations of surviving whether medium or long term. Authors report their experience as regards to observation of two(More)
