The Role of Metals in beta-Amyloid Peptide Aggregation: X-Ray Spectroscopy and Numerical Simulations
No full textThe aim of this review is to show how the challenging problem of understanding the physico-chemical basis of protein misfolding and aggregation which are at the origin of plaque formation in amyloid pathologies can be successfully investigated with a combination of modern spectroscopic techniques and advanced first principle numerical simulations. Within the vast group of diseases (more than 20) characterized by extra-cellular deposition of fibrillar material and generically called Amyloidosis, we shall focus on the Alzheimer's disease, a progressive and devastating neurodegenerative pathology affecting an important fraction of the world aged population. Well identified peptides (the so called A beta peptides) undergo a misfolding process during the development of the disease. An important, but not yet fully elucidated, r le appears to be played in these processes by transition metals (mainly copper and zinc) that have been observed to be present in large amounts in patient's neurological plaques. Starting from this observation, a number of interesting results concerning the structural properties of the relevant metalpeptide binding site, emerging from the interplay between X-ray Absorption Spectroscopy experiments, and ab initio molecular dynamics simulations of the Car-Parrinello type will be reported and discussed
Ultrasound exploration in the work-up of unexplained fever in the immunocompromized host: preliminary observations.
No full textIn immunocompromized hosts, febrile episodes
have an unknown origin (FUO) in about fifty per
cent of cases. In this preliminary study we evaluated
the role of abdominal and pleural ultrasound
(US) examination for early detection of infectious
sites. US exploration was performed in a cohort of
14 consecutive FUO patients early after fever
onset, at patients’ bedside, by a hematologist
trained in diagnostic ultrasound, and it was
repeated at neutrophil recovery. US exploration
showed abnormal abdominal findings in 7 and
pleural effusion in 3 patients. In all cases but one
the abnormality was found at the first US examination.
Abdominal and pleural US exploration is a
low-cost, easy to use tool for the work-up of FUO
in the immunocompromized host that proved to
be effective in identifying the infection site in about
50% of patients
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
