PULMONER HİPERTANSİYONU OLAN ÇOCUKLARDA SERUM HOMOSİSTEİN, ASİMETRİK DİMETİLARJİNİN VE NİTRİK OKSİT DÜZEYLERİ
No full textBu çalıĢma, PAH’ı olan ve olmayan hasta grupları ile sağlıklı kontrol grubunda Homosistein, ADMA ve NO düzeyleri çalıĢılarak, bu belirteçlerin ekokardiyografi ve kateter anjiografi bulgularıyla olan iliĢkilerini araĢtırmak amacıyla yapılmıĢtır.
ÇalıĢmaya, PAH tanısı alan 30, soldan sağa Ģantı olup PAH geliĢmemiĢ 20 DKH ile 20 sağlıklı kontrol grubundan oluĢan toplam 70 olgu dahil edilmiĢtir. Olguların detaylı öykü ve fizik incelemeleri, antropometrik ölçümleri, tele, EKG, EKO, kateter anjio ve tam kan bulguları daha önceden hazırlanmıĢ olan formlara kaydedilmiĢtir. Tüm olgulardan alınan kan örneklerinde Homosistein, ADMA ve NO düzeyleri ELISA yöntemiyle çalıĢılmıĢtır.
PAH olgularının 15’i (%50) kız, 15’i (%50) erkek olup yaĢları 12 ay ile 26 yıl arasında, DKH olgularının 12’si (%60) kız, 8’i (%40) erkek olup yaĢları 2 ay ile 16 yıl arasında değiĢmekteydi. PAH olgularının homosistein düzeylerinin, DKH ve sağlıklı kontrol olgularından yüksek olduğu (p0,05). PAH grubundaki olguların siyanotik ve asiyanotik Ģeklinde ayrılan alt gruplarının karĢılaĢtırmasında ise Homosistein düzeylerinin siyanotik olgularda anlamlı biçimde yüksek olduğu belirlenmiĢtir. PAH olgularının SPAB, DPAB, OPAB, Rp ve Rp/Rs değerlerinin
DKH grubuna göre daha fazla olduğu saptanmıĢtır (p<0,05). PAH’lı grubun EKO ölçüm değerleri ve hemodinamik parametreleri ile Homosistein, ADMA ve NO düzeyleri arasında korelasyon olmadığı görülmüĢtür.
PAH grubunda artmıĢ Homosistein ve ADMA düzeylerinin PAH’a yol açan diğer faktörlerle birlikte PAH geliĢimine katkıda bulunduğunu, bu biyobelirteçlerin PAH olgularının izlemlerinde kullanılan standart izlem parametrelerine ilave edilmesi ve daha geniĢ PAH topluluklarına uyarlanması için kullanılırlığının büyük, çok merkezli ve prospektif çalıĢmalarla gösterilmesinin gerekli olduğunu düĢünmekteyiz

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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
Full text linkAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
