Adaptation to nocturnal intermittent hypoxia in sleep-disordered breathing: 2,3 diphosphoglycerate levels: a preliminary study
Authors:
Publisher and Date:(2002)An inexpensive method for determining significant sleep-related hypoxemia would be beneficial for patients being investigated and treated for sleep-disordered breathing in order to distinguish hypoxic patients from those without nocturnal hypoxemia. Since 2,3 diphosphoglycerate (DPG) which profoundly affects dissociation of O2 from hemoglobin is an instrumental substance in determining the O2 affinity of blood it becomes important to consider in what extent the nocturnal intermittent hypoxemia may ...

Effects of cold stress on early and late stimulus gating
Authors:
Publisher and Date:(Elsevier Ireland Ltd., 2005)The P50 component of the event-related potential (ERP) mainly reflects early pre-attentional processing. Along with P50 the N100 component and mismatch negativity (MMN) were postulated to represent a complex multistage and multi-component gating system. If some variable threshold or gating is exceeded by the MMN signal the MMN is often followed by a relatively sharp fronto-central positive wave the P3a component which reflects an attentional switch to an environmental change. The P50 was shown to ...

Uykusuzluk süresince ve sonrasında opsonizasyon
Authors:
Publisher and Date:(AVES YAYINCILIK, 2002)Bu çalışmada, 48 saat uykusuzluğun, fagositik aktiviteyi belirleyen göstergelerden biri olan opsonizasyon üzerine etkileri araştırıldı. Sağlıklı, genç erişkin 10 erkek gönüllü çalışmaya dahil edildi. Fizik muayene sonrasında, denekler, uyku bozukluğu açısından değerlendirilmek amacıyla bir gece poligrafik uyku kayıdına alındılar. Uyku tetkikini takiben 48 saat süre ile sedanter koşullarda uykusuz bırakılan denekler, yine kayıt altında telafi uykularını uyudular. 0 -24 - 48 ve 72. saatlerde venöz ...
