Eating attitudes, body image satisfaction and self-esteem in Turkish adolescents.
Batı ülkelerinde bozulmuş yeme davranışları ve zayıflık arzusunun ergenler arasında yaygın olduğu bilinmesine rağmen, gelişmekte olan ülkelerde bu konuyla ilgili veriler kısıtlıdır. Türkiye hızla gelişen bir ülkedir ve Türk ergenler Avrupa ve Asya değerlerinden etkilenmektedir. Özellikle genç Türk popülasyonunda yeme davranışlarındaki değişimi takip edebilmek için klinik dışı örneklemlerde gerçekleştirilecek çalışmalar ihtiyaç vardır.
Bu çalışmanın temel amacı Türk ergen grupta bozulmuş yeme tutum ve davranışlarını değerlendirmektir. 38 soruluk bir sosyo-demografik değerlendirme formu, Yeme Bozuklukları Değerlendirme Ölçeği (EDE-Q), Yeme Tutumu Testi (EAT-40), Beden İmgesi Memnuniyeti Anketi (BISQ) ve Rosenberg Benlik Değeri Skalası kullanılmıştır. Farklı sosyo-ekonomik düzeylerden, İstanbul'u temsil eden bir kaç orta okul ve liseden ortalama yaşları 15.52 (min-max=12-18, SD=1.88) olan 626 kız ve 299 erkek çalışmaya dahil edildi. Ergenlerin çoğu (%90) anne ve babalarıyla yaşıyordu. Annelerin çoğu (%47.4) ilkokul mezunuyken, babaların çoğu (%37.8)lise mezunuydu.
Ortalama BKİ 20.90 (SD=3.38)'dı. Sadece 11 kız (%1.8) ve 4 erkek (%1.3) için BKİ>30 iken, 84 kız (%14) ve 29 erkek (%10) için BKİ<17.5 (p<0.05) idi. BKİ kategorilerinin, beden imgesi memnuniyetsizliği, zayıflık arzusu, bozulmuş yeme tutumunun bir fonksiyonu olarak kız ve erkeklerin sıklık dağılımları farklılaşmakta idi. Karşılaştırmalı sonuçlar kız ve erkekler arasında SES açısından anlamlı bir fark göstermezken, BKİ, EDE-Q toplam ve alt-ölçekler, EAT-40 ve BISQ skorlarının cinsiyetin bir fonksiyonu olarak farklılaştığını göstermektedir. SES'e göre düşük benlik saygısı skorları olan kişiler, tüm alt ölçeklerde ve toplam EDE-Q da yüksek skorlar almışlardı.
Bu çalışma bozulmuş yeme tutumu ve davranışlarının özellikle pek çok Türk kız lise öğrencisi arasında bulunduğuna işaret etmektedir. Bu veriler, ergen kızların yeme bozuklukları açısından taranması ve bu grup için birincil ve ikincil müdahalelerin hedeflenmesi gerektiğini düşündürmektedir
Visualisation, VISC and scientific insight
First paragraph:The report by McCormick et al (1987) on Visualisation in Scientific Computing (ViSC) played a major role in drawing attention to the increasing need and scope for visual computing. There is no doubt that developments in computer-based technology will greatly extend human capacity for visualisation. The invention of the microscope and telescope led to breakthroughs in many scientific disciplines. These tools not only enabled Man to see the otherwise unseeable but they also enabled empirical evaluation of pre-existing theory. Similarly, imaging systems and computer graphics are further enabling Man to see the unseeabl~ and are becoming vital tools of research in some disciplines . A wide range of phenomena , which exist either outside our sensory limits or which exist only in our imagination, may berendered visual. The technology for this is already well developed and the euphoria over ViSC is justifiable

NDRG1 expression in trophoblast cell lines in response to hypoxia or CoCl<sub>2</sub>.
<p>NDRG1 (upper panels) and tubulin (loading control, lower panels) were detected using Western immunoblot. (A) NDRG1 expression in trophoblasts and trophoblast-derived choriocarcinoma cell lines, as well as in other cell types under standard conditions. (B) NDRG1 expression in JEG-3 cells cultured in standard conditions, 24 h of hypoxia (<1% O<sub>2</sub>) or the hypoxia mimetic CoCl<sub>2</sub> (200 µM). The expression of HIF-1α (middle panel) confirmed the effect of CoCl<sub>2</sub> or hypoxia. (C) A time course and concentration-dependent stimulation of NDRG1 expression in JEG-3 cells exposed to the hypoxia mimetic agent CoCl<sub>2</sub>. Data are representative of at least three independent experiments.</p
The impact of non-hypoxic cell injury on NDRG1 expression in trophoblast lines.
<p>(A) BeWo cells were incubated for either 24 or 48 h in standard, serum-containing medium or in serum-free medium. NDRG1 was detected by Western immunoblot (upper panel), and tubulin (lower panel) used for loading control.
