2. 1. Synthesis and Characterization of Nanoprobes for X-Ray Fluorescence Computed Tomography (XFCT) Bio-imaging

   Author : Yuyang Li; Muhammet Toprak; Hans Hertz; Ender Suvaci; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : X-ray fluorescence computed tomography (XFCT) is an emerging biomedical imaging technique. The KTH-XFCT laboratory system offers a characteristic 24 keV emission line, and high spatial resolution (200 ?m) images. XFCT as a newly emerging modality also requires the exploration and development of suitable contrast agents. READ MORE

4. 2. Novel mechanism of action of antipsychotic drugs : effects on neuropeptides in rat brain

   Author : Susanne H M Gruber; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Schizophrenia; D-amphetamine; Antipsychotic drugs; Neurotensin; Neuropeptide Y; Rat brain; Microdialysis;

   Abstract : Schizophrenic patients have been reported to have lower concentrations of neurotensin (NT)-like immunoreactivity (-LI) in their cerebrospinal fluid (CSF) that normalize after treatment with antipsychotic drugs. Schizophrenic patients also had higher CSF concentrations of neuropeptide Y (NPY)-LI compared to controls, thus involvement of NPY in the disease has also been suggested. READ MORE

5. 3. Performance of MCrAlX coatings : Oxidation, Hot corrosion and Interdiffusion

   Author : Pimin Zhang; Ru Lin Peng; Xin-Hai Li; Sten Johansson; Ping Xiao; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : MCrAlY coatings (M=Ni and/or Co) are widely used for the protection of superalloy components against oxidation and hot corrosion in the hot sections of gas turbines. The drive for coating systems to bestow adequate oxidation and corrosion resistance upon the components becomes urgent as an inevitable result of the necessary improvement in engine combustion efficiency and service lifetime.

6. 4. Bilateral neurogenic mechanisms following acute unilateral inflammation

   Author : Indre Bileviciute-Ljungar; Karolinska Institutet; Karolinska Institutet; []
   Keywords : bilateral changes; host defence reaction; contralateral treatment; dorsal root reflexes; cross-spinal reflexes; substance P; neurokinin A; calcitonin gene-related peptide; neuropeptide Y; nociception; inflammation; carrageenan; edema; hindpaw withdrawal latency; microdialysis; hot-plate test; Randall Selitto test;

   Abstract : The contribution of neurogenic mechanisms to inflammation has been extensively studied during the last decade, but provides no clear understanding of the bilateral changes commonly seen following unilateral stimulation. This work demonstrates that bilateral neurogenic mechanisms are a part of general host defence reactions following acute unilateral challenge, for the first time revealing that local anaesthetics applied contralaterally, might be used for therapeutic purposes in relieving pain and inflammation.

7. 5. Surface characterization of 2D transition metal carbides (MXenes)

   Author : Ingemar Persson; Per Persson; Justinas Palisaitis; Johanna Rosén; Vanya Darakchieva; Vincent Mauchamp; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Research on two-dimensional (2D) materials is a rapidly growing field owing to the wide range of new interesting properties found in 2D structures that are vastly different from their three-dimensional (3D) analogues. In addition, 2D materials embodies a significant surface area that facilitates a high degree of surface reactions per unit volume or mass, that is imperative in many applications such as catalysis, energy storage, energy conversion, filtration, and single molecule sensing.
