2. 1. Ion channels and electrical activity in vascular smooth muscle: Effects of calcium store depletion, cholesterol and cholesterol-lowering drugs

   Author : Andreas Bergdahl; Kärlfysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; statins; endothelin; cholesterol; caveolae; smooth muscle; TRP; Ca2 channels; SOC;

   Abstract : Smooth muscle cells (SMCs) in the vessel wall contract to regulate blood flow and pressure, a function essential for normal circulation through tissues. On the other hand, migration and proliferation of SMCs are important factors in vascular disease, such as atherosclerosis and restenosis following surgical dilatation. READ MORE

4. 2. Characterization of Small Antennas & Wireless Devices for MIMO Systems in Multipath & Line-of-Sight

   Author : Ahmed Hussain; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; USRP; OTA; SDR; RIMP; TRP; TIS; Reverberation chamber; Rayleigh; MIMO; LOS; LTE; Throughput;

   Abstract : The current thesis investigates over-the-air (OTA) performance characterization of small antennas and wireless terminals in rich isotropic multipath (RIMP) environment, as well as in pure line-of-sight (LOS) environment when taking into account the random positions and orientations of the mobile terminals caused by the realistic user behavior. The latest mobile wireless terminals such as smart phones and tablets can be used in any random orientation thereby making even a received LOS-component appear as a random voltage at the antenna ports over time.

5. 3. Beyond AMPA and NMDA: Slow synaptic mGlu/TRPC currents : Implications for dendritic integration

   Author : Marcus Petersson; Erik Fransén; Abdel El Manira; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; transient receptor potential; TRP; metabotropic glutamate receptor; mGlu1 5; dendritic integration; synaptic activation; temporal summation; low-frequency; entorhinal cortex; mathematical model; computational neuroscience; Computer science; Datavetenskap;

   Abstract : In order to understand how the brain functions, under normal as well as pathological conditions, it is important to study the mechanisms underlying information integration. Depending on the nature of an input arriving at a synapse, different strategies may be used by the neuron to integrate and respond to the input. READ MORE

6. 4. Dendritic and axonal ion channels supporting neuronal integration : From pyramidal neurons to peripheral nociceptors

   Author : Marcus Petersson; Erik Fransén; Theodore Cummins; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ion channels; computational modeling; simulations; dendrites; axons; TRP; hippocampus; C-fiber nociceptors; pain;

   Abstract : The nervous system, including the brain, is a complex network with billions of complex neurons. Ion channels mediate the electrical signals that neurons use to integrate input and produce appropriate output, and could thus be thought of as key instruments in the neuronal orchestra. READ MORE

7. 5. Distribution and function of TRP ion channels in primary sensory neurons

   Abstract : It is frequently argued that cannabinoids exert part of their analgesic and anti-inflammatory effects via activation of the cannabinoid CB1 receptor located on TRPV1-expressing primary sensory nerve fibres in peripheral tissues. However, we find no evidence of CB1 receptor immunoreactivity on nerve fibres in rat or mouse hindpaw skin and mesenteric artery. READ MORE
