A process model of the formation of spatial presence experiences

In order to bridge interdisciplinary differences in Presence research and to establish connections between Presence and “older” concepts of psychology and communication, a theoretical model of the formation of Spatial Presence is proposed. It is applicable to the exposure to different media and intended to unify the existing efforts to develop a theory of Presence. The model includes assumptions about attention allocation, mental models, and involvement, and considers the role of media factors and user characteristics as well, thus incorporating much previous work. It is argued that a commonly accepted model of Spatial Presence is the only solution to secure further progress within the international, interdisciplinary and multiple-paradigm community of Presence research

Mikrochirurgische Brustrekonstruktion mittels freier ALT-Lappenplastik als Rückzugsoption bei einer Patientin mit adultem Morbus Still: Eine Falldarstellung

The deep inferior epigastric artery perforator (DIEP) flap is an excellent option for microsurgical breast reconstruction. In selected cases, e.g. in case of previous abdominoplasty, other autologous options like transverse upper gracilis (TUG) or superior gluteal artery perforator (sGAP) flaps can be considered. The anterolateral thigh (ALT) flap is reported to be used as a salvage procedure in selected cases of breast reconstruction, where other flaps were not available or failed. We present a case of a 41-year-old woman who was undergoing bilateral breast reconstruction after bilateral mastectomies following implant-based mastopexie and multiple infections. She also suffered from an adult onset Still's disease (AOSD) and was thus immunosuppressed. Microsurgical breast reconstruction was performed in a two-stage procedure. The left breast was reconstructed using a TUG flap. On the right side the TUG reconstruction failed due to vascular anomaly, so an ALT flap was successfully used instead. The whole procedure was accompanied by a multidisciplinary approach including a rheumatological complex treatment and enabled a successful bilateral breast reconstruction in this challenging case.Die DIEP- (deep inferior epigastric artery perforator) Lappenplastik gilt als Goldstandard in der mikrochirurgischen Brustrekonstruktion. In ausgewählten Fällen, wie zum Beispiel nach vorangegangener Bauchdeckenstraffung, können andere Eigengewebstransfers wie die TMG- (transverse myokutane Gracilislappenplastik) oder sGAP- (superior gluteal artery perforator) Lappenplastik erwogen werden. Die ALT- (anterolateral thigh) Lappenplastik ist als Rückzugsoption in wenigen Fällen der Brustrekonstruktion beschrieben, wenn andere Lappenplastiken nicht verfügbar waren oder nach Scheitern einer initialen mikrochirurgischen Brustrekonstruktion. Wir präsentieren den Fall einer 41-jährigen Patientin mit bilateraler mikrochirurgischer Brustrekonstruktion nach bilateraler Mastektomie in Folge einer implantatbasierten Augmentationsmastopexie und multipler Infektionen. Sie litt zudem an einem adulten Morbus Still und war daher immunsupprimiert. Im Rahmen einer zweizeitigen bilateralen Brustrekonstruktion wurde zunächst die linke Brust durch eine TMG-Lappenplastik von rechts rekonstruiert. Die Rekonstruktion der rechten Brust durch eine geplante TMG-Lappenplastik von links war aufgrund einer vaskulären Variante nicht möglich, sodass eine Rekonstruktion durch eine ALT-Lappenplastik erfolgte. Die gesamte Behandlung wurde interdisziplinär von einer rheumatologischen Komplexbehandlung begleitet und nur so war eine erfolgreiche bilaterale Brustrekonstruktion in diesem herausfordernden Fall möglich

Iron and zinc absorption in human subjects from a mixed meal of extruded and nonextruded wheat bran and flour

The effect of extrusion cooking of a bran-flour mixture on iron and zinc retention was measured in normal adults. The stable isotopes 58Fe (1.253 mg) and 67Zn (5.13 mg) were administered with 40 g nonextruded or extruded cereal with milk and isotopic retention was measured from fecal excretion over the next 4-7 d by neutron-activation analysis (Fe) and fast-atom-bombardment mass spectrometry (Zn). 58Fe retention was 15.1 +/- 2.4% (means +/- SEM) with the nonextruded meal and 16.5 +/- 2.7% with the extruded meal. 67Zn retention was 18.9 +/- 1.7% with the nonextruded meal and 18.3 +/- 1.5% with the extruded meal. Extrusion cooking had no effect on 58Fe or 67Zn retention
