2. 1. Preclinical X-Ray Fluorescence Imaging with Multifunctional Nanoparticles

   Author : Giovanni Marco Saladino; Hans Hertz; Muhammet Toprak; Stefan Andersson-Engels; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

   Abstract : X-ray fluorescence imaging (XFI) is an emerging technique for preclinical studies, characterized by high resolution, specificity, and sensitivity. It relies on nanoparticles (NPs) as contrast agents, which must be constituted of specific elements that match the X-ray source energy for detection. READ MORE

4. 2. Active and passive seismic methods for investigating the glacially-triggered Burträsk fault

   Author : Ruth A. Beckel; Christopher Juhlin; Alireza Malehmir; Lars Nielsen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Burträsk fault; Glacially-triggered faulting; Crooked-line reflection seismics; Cross-dip correction; Stacking-based location; Microearthquake source observations; Passive seismic imaging; Seismic interferometry; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

   Abstract : Glacially-triggered faults are of high scientific interest since their formation was likely accompanied by major earthquakes and they are still a centre of seismicity in northern Fennoscandia, today. Imaging their deeper structure mainly relies on reflection seismics since the method generally has the best resolving power at depth of all geophysical methods. READ MORE

5. 3. Reconfigurable and Wideband Receiver Components for System-on-Chip Millimetre-Wave Radiometer Front-Ends

   Author : Shakila Bint Reyaz; Robert Malmqvist; Anders Rydberg; Luca Roselli; Uppsala universitet; []
   Keywords : Reconfigurable; Wideband; Receivers; Millimetre-Wave; Radiometers; System-on-Chip; Passive Imaging.; Engineering Science with specialization in Microwave Technology; Teknisk fysik med inriktning mot mikrovågsteknik;

   Abstract : This thesis presents solutions and studies related to the design of reconfigurable and wideband receiver circuits for system-on-chip (SoC) radiometer front-ends within the millimetre-wave (mm-wave) range. Whereas many of today’s mm-wave front-ends are bulky and costly due to having discrete RF components, single-chip receiver modules could potentially result in a wider use for emerging applications such as wireless communication, short range radar and passive imaging security sensors if realised with adequate performances and at a lower cost.

6. 4. Brain processing of experimental muscle pain and its interrelation with proprioception and muscle fatigue : positron emission tomography study

   Author : Alexander Korotkov; Docent Tomas Graven-Nielsen; Umeå universitet; []
   Keywords : Experimental muscle pain; Hypertonic saline; Kinesthesia; Proprioception; Movement; Vibration; Muscle fatigue; Brain; Imaging; Positron emission tomography; Regional cerebral blood flow;

   Abstract : Chronic muscle pain is a significant medical and social problem and better understanding of the pathophysiological mechanisms involved is an important requirement for further development of diagnostics, treatment and rehabilitation methods. Experimental imaging studies have investigated functional neuroanatomy of different pain components. READ MORE

7. 5. Chronic Tennis Elbow : Aspects on Pathogenesis and Treatment in a Soft Tissue Pain Condition

   Author : Magnus Peterson; Kurt Svärdsudd; Margaretha Eriksson; Harald Breivik; Uppsala universitet; []
   Keywords : tennis elbow; pain; chronic; soft tissue; imaging; PET; RCT; survey; treatment; exercise; eccentric; concentric; epicondylosis; epicondylitis; tendinosis; tendinitis;

   Abstract : Objectives: To study the treatment practice of chronic tennis elbow (TE) among general practitioners (GPs) and physiotherapists (PTs), the effects of a simple, graded home exercise regime versus expectation, the effects of eccentric versus concentric exercise, and the involvement of the substance P – NK1 receptor system in the peripheral, painful tissue of chronic TE patients by positron emission tomography (PET). Materials and methods: A postal survey regarding therapeutic methods used in patients with chronic TE was sent to 129 GPs and 77 PTs, 81 subjects with chronic TE were randomly and blindly assigned to either an exercise group or a wait list group, 120 subjects were randomly assigned to either eccentric or concentric exercise and ten subjects were examined by PET and the NK1 specific radioligand [11C]GR205171.
