  2. 21. Role of Inducible Nitric Oxide Synthase and Melatonin in Regulation of β-cell Sensitivity to Cytokines

    Author : Annika K. Andersson; Stellan Sandler; Nils Welsh; Décio L. Eizirik; Nils Billestrup; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; β-cell; Cyclooxygenase; Cytokine; Diabetes; IFN-γ; IL-1β; iNOS; Insulin; Melatonin; Nitric oxide; Pancreatic islets; Phospholipase D; Prostaglandin E2; Streptozotocin; Cellbiologi; Cell biology; Cellbiologi;

    Abstract : The mechanisms of β-cell destruction leading to type 1 diabetes are complex and not yet fully understood, but infiltration of the islets of Langerhans by autoreactive immune cells is believed to be important. Activated macrophages and T-cells may then secrete cytokines and free radicals, which could selectively damage the β-cells. READ MORE

  4. 22. Arsenic Influences Virus Replication in Experimental Coxsackievirus B3 Infection

    Author : Ylva Molin; Nils-Gunnar Ilbäck; Eva Hjelm; Göran Friman; Jonas Blomberg; Gunnar Nordberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coxsackievirus B3; trace elements; arsenic; selenium; virology; IFN-γ; NFκB; Infectious diseases; Infektionssjukdomar; Infectious Diseases; Infektionssjukdomar;

    Abstract : Trace elements are essential for the host defence against infections, and during common infections, the balance of trace elements is changed in serum and tissues. Supplementation with selenium (Se), an essential trace element, is known to decrease the severity of coxsackievirus B3 (CVB3) infection in mice. READ MORE

  5. 23. Notch Signaling in Neuroblastoma and Renal Cell Carcinoma

    Author : Jonas Sjölund; Institutionen för translationell medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; differentiation; clear cell renal cell carcinoma; neuroblastoma; TGF-beta; migration; γ-secretase; valproic acid; cancer; Notch; ERK; von Hippel-Lindau; hypoxia;

    Abstract : The Notch signaling pathway governs cell functions essential for normal development and organogenesis. Aberrant Notch signaling has been implicated in tumorigenesis by perturbing control of proliferation, differentiation, apoptosis, migration and angiogenesis. READ MORE

  6. 24. Mechanisms of the intracellular survival of Francisella tularensis

    Author : Linda Tancred; Anders Sjöstedt; Jean Celli; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella tularensis; Igl; MglA; J774; IFN-γ; RNS; ROS; phagosome; Clinical bacteriology; Klinisk bakteriologi; mikrobiologi; Microbiology;

    Abstract : Francisella tularensis is a gram-negative, highly virulent, intracellular bacterium which causes the zoonotic disease tularemia. The subspecies tularensis and holarctica are clinically important, and the former is the more virulent. The intracellular lifestyle of F. READ MORE

  7. 25. Microstructure of Alumina (Al2O3) Grown by Oxidation of FeCrAl Alloys and by Chemical Vapour Deposition

    Author : Sead Canovic; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; γ-Al2O3; TiN; κ-Al2O3; TiC; FeCrAl alloys; CVD; oxidation; α-Al2O3;

    Abstract : This thesis consists of two parts: the detailed microstructure of (i) CVD alumina multilayer coatings, and (ii) alumina scales formed on three different FeCrAl alloys. The coatings and oxide scales were characterized by using analytical electron microscopy and different surface analysis techniques. READ MORE
