Concentrations of chlorinated pollutants in adipose tissue of yellow-legged gulls (Larus michahellis) from Spain: Role of gender and age
No full textConcentrations of 7 different polychlorinated biphenyl (PCB) congeners, and eleven organochlorine pesticides
(OCPs) and metabolites, including DDTs (dichlorodiphenyltrichloroethane), HCHs (hexachlorocyclohexane
isomers), Endosulfan, Endosulfan sulfate, Endrin, Dieldrin and HCB (hexachlorobenzene), were determined in
adipose tissue of 57 yellow-legged gulls collected from NW and N Spain. Furthermore, the possible differences
due to two endogenous factors, age and gender, were determined. All the analyzed PCBs were detected in over
66% of the samples, with levels of 291.9 (PCB 180), 34.5 (PCB 118), 0.7 (PCB 28), 432.6 (PCB 153), 225.5 (PCB
138), 1.3 (PCB 101) and 0.4 (PCB 52) ƒÊg/kg of adipose tissue. With respect to the OCPs and metabolites, only
4,4Œ-DDE and HCB were detected in more than 50% of the samples, with means of 360.6 and 2.5 ƒÊg/kg of adipose
tissue, respectively. From all the considered contaminants, only 4,4Œ-DDE levels presented significant differences
depending on the gender, with females showing higher values than males (p < 0.01). Significant differences
(p < 0.001) were also found related to age for the levels of PCBs 180, 138, 101, 28 and 153, as well as 4,4Œ-DDE,
with adult levels being higher than those in young birds. The results of the present study constitute a baseline to
better assess the environmental impacts of PCB and OCP contamination at other coastal sites for future biomonitoring
studies, with particular emphasis on gender- and age-related differences
Cannabinoid-Based Medicines and Multiple Sclerosis
No full textThe emerging role of the endocannabinoid system (ECS) in the control of symptoms and disease progression in multiple sclerosis (MS) has been highlighted by recent studies. MS is a chronic, immune-mediated, and demyelinating disorder of the central nervous system with no cure so far. It is widely reported that cannabinoids might be used to control MS symptoms and that they also might exert neuroprotective effects and slow down disease progression. The aim of this chapter is to give an overview of the main endogenous and synthetic cannabinoids used for the symptomatic amelioration of MS and their beneficial outcomes, providing new possible perspectives for the treatment of this disease
Industry Science Relations: A Erik Project and the Policy Recommendations
No full textIn recent years a wide debate involving academics and policy makers has been taking place all over Europe regarding the new role that universities can have in the development and strengthening of industry at national level. The debate has grown up in the wake events in the USA where, for a long time, universities have been undergoing structural repositioning in order to better meet the technological needs of the market. More and more interest is developing around the so-called university ‘third mission’. The thesis sustains that the two traditional missions already carried out by universities – teaching and research – should indeed integrated with a third one: an academic capacity to provide direct contributions to industr
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
L'impianto della protesi di Swanson nel morbo di Kienboeck
No full textThe authors report twenty-one cases in which the Swanson prosthesis was used in the treatment of Kienböck's disease. Eighteen of the patients were followed up after between six months and seven years. The results were good in 94.5 per cent of cases. The operation resulted in all cases in the disappearance or reduction of pain. In many instances it also improved the mobility of the wrist and the strength of the muscles. The prosthesis was found to be well tolerated with time. The results were also good in the advanced stages of the disease

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
