First prenatal diagnosis of familial hypercholesterolemia by a molecular biology technic
No full textThe first prenatal diagnosis for exclusion of homozygous familial hypercholesterolemia by using the so called technique of Restriction Polymorphism Fragment Length (RFLP's) on chorial villus DNA, was performed. The test was used when the mother of a seven-year-old child with homozygous familial hypercholesterolemia, became pregnant. Previous examination of DNA of both parents and of one hypercholesterolemic child, showed a mutation of the gene encoding for the synthesis of LDL-receptor. The comparison between first degree relatives RFLP's and the chorial villus RFLP's, showed the absence of a previously recognized mutation in the foetus. After a normal pregnancy, the child was born and his plasma cholesterol was within the "normal" range

No full textPURPOSE:
State of the art of LDL-apheresis and treatment of severe familiar hypercholesterolemia.
PATIENTS AND METHODS:
Clinical experience of treatment with LDL-apheresis of pediatric and adult patients with familial hypercholesterolemia using the following techniques: D.A.L.I., H.E.L.P., D.S.C.
RESULTS:
The outcome of treatment with LDL-apheresis in young patients, using the most recently introduced techniques, is reported. We have submitted to LDL-apheresis 11 pediatric patients. The youngest is aged 3.5. LDL-apheresis is able at improving the metabolic impairment and halting the natural evolution of atherosclerotic disease and atherosclerotic complications.
CONCLUSIONS:
At present, LDL-apheresis is the most effective and safe therapeutic approach to the treatment of homozygous, heterozygous and double heterozygous familial hypercholesterolemia
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
