CHANGES OF NEUROENDOCRINE AXES IN PATIENTS WITH MENSTRUAL MIGRAINE
No full textMenstrual migraine (MM) is a menstrually related disorder (MRD) characterized by several symptoms in common with premenstrual syndrome (PMS). It has been hypothesized that in both MM and PMS hormonal cyclicity could change the balance of neurotransmitters and neuromodulators like monoamine and opioid. In this article we analyze all the data collected by our group on the central opioid tonus and the adrenergic and serotonergic systems in patients affected by menstrual migraine
The 6-hydroxydopamine model: News from the past
No full textThe investigation of pathogenic and pathophysiological mechanisms of Parkinson's disease relies on experimental models reproducing, in the animal, the pathological and behavioural features of the disease. Despite the availability of innovative models, 6-hydroxydopamine (6-OHDA) remains the most widely used tool to induce a nigrostriatal lesion in the animal (rat). This is due to (1) the relatively low complexity and cost of the procedure, (2) the fact that the 6-OHDA-induced lesion is highly reproducible, and (3) the versatility of the procedure, which can yield varying degrees of nigrostriatal lesions that develop with different temporal profiles, depending on the site chosen for the toxin injection. © 2008 Elsevier Ltd.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
