Effects of exercise on platelet indices in well-trained athletes
No full textWe have now examined the platelet indices -platelet count (PC), mean platelet volume (MPV), platelet dimensional vidth (PDW)- in two groups of highly-trained athletes before and after exercise. The PC increased significantly after the biathlon race,
whereas during less strenuous exercise, such as the
runners'basal training, PC did not change. The exercise-induced
thrombocytosis did not depend on hemoconcentration since the
hematocrit values in our biathletes did not significantly change
after the effort. No platelet indices correlated with Km/h. Thus according to previous reports the thrombocytosis due to platelet release would be more appreciable in short and stressful exercising than in prolonged
and regular activities, such as in training.On the other hand
both after racing and after training a significant decrease of
MPVs was associated vith raised PDW; furthermore a lowered MPV
vas observed even after the first short-term effort (cycling) of
the biathlon race. These findings would suggest that the
variation of platelet size,observed in all the exercising
athletes, may be due to the release of platelets from those seats
of pooling (splenic and non-splenic) previously reported by
others
La stele di Camin: nuovi dati per la ricostruzione del contesto
No full textThe stele of Camin is the oldest of the figured funerary stelae of pre-Roman Padua and represents a fundamental evidence of the social and mobility dynamics active in the center of Padua at the time of the transition to the urban phase. Through
a systematic re-examination of the publications chronologically closest to the discovery and through extensive archival research, the contribution aims to provide new data both on the original context of the stele and on the exact location of the stele’s discovery site, aspects that have so far been neglected in the vast literature on the monument
PLATELET COUNT, MEAN PLATELET VOLUME, AND PLATELET DIMENSIONAL WIDTH IN RUNNERS DURING BASAL TRAINING
No full textPhysical efforts were reported increase unconstantly platelet count
as well as mean platelet volume (MPV). However these findings,
dependent on some mechanisms occuring in the exercise, i.e. hemoconcentration, change of platelet splenic pooling,
increased production of platelets. Till now it is not well clarified if
the changes of platelet indexes may represent a persistent pattern in well trained athletes. Thus in the present research PC, MPV, and platelet dimensional width (PDW) were compared between a group of long distance runners, during basal training, and a group of sedentary healthy subjects.
Thirty-four runners, ten females and twenty-four males (aged 20-45 years,covering 50 to 160 km/week), as well as thirty-four healthyuntrained non-smoking volunteers (aged 18-46 years) of both sexes were admitted to the study:
The mean PCs as well as the MPV from male and female groups of runners did not differ from the respective groups of controls. PDW was significantly different between male runners and
control, as well as between female runners and controls.
PC, MPV and PDW did not correlate with the runners' age and the kilometers weekly covered

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
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
