1. 1. Major Intrinsic Proteins - Structure, function, interactions

   Författare :ANDREAS KIRSCHT; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aquaporin; membrane proteins; crystallography; stopped-flow; molecular dynamics; structure modeling;

   Sammanfattning : Major intrinsic proteins, also referred to as aquaporins (AQPs) are localized in membranes of all domains of life to increase the permeability to water or other small, polar molecules. Several monophyletic groups can be discerned in this large and divergent protein superfamily. LÄS MER

3. 2. Stochastic modeling of motor proteins

   Författare :Martin Lindén; Mats Wallin; Dean Astumian; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular motor; motor protein; Markov process; fluctuations; statistical mechanics; microscopic reversibility; Physics; Fysik;

   Sammanfattning : Motor proteins are microscopic biological machines that convert chemical energy into mechanical motion and work. They power a diverse range of biological processes, for example the swimming and crawling motion of bacteria, intracellular transport, and muscle contraction. LÄS MER

4. 3. Modeling of voltage-gated ion channels

   Författare :Pär Bjelkmar; Erik Lindahl; Toby W. Allen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular modeling; Molecular dynamics; Voltage-gating; Ion channels; Protein structure prediction; Chemistry; Kemi; biokemi; inriktning teoretisk kemi; Biochemistry with Emphasis on Theoretical Chemistry;

   Sammanfattning : The recent determination of several crystal structures of voltage-gated ion channels has catalyzed computational efforts of studying these remarkable molecular machines that are able to conduct ions across biological membranes at extremely high rates without compromising the ion selectivity. Starting from the open crystal structures, we have studied the gating mechanism of these channels by molecular modeling techniques. LÄS MER

5. 4. Modeling and simulation of intrinsically disordered proteins

   Författare :Joao Henriques; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Intrinsically disordered proteins; Coarse-grained models; Atomistic models; Metropolis Monte Carlo simulations; Molecular dynamics simulations; Sampling; Conformational analysis; Charge regulation; Surface adsorption;

   Sammanfattning : This work is primarily about the development, validation and application of computer simulation models for intrinsically disordered proteins, both in solution and in the presence of uniformly charged, ideal surfaces. The models in question are either coarse-grained or atomistic in nature, and their applications are dependent on the specific purpose of each study. LÄS MER

7. 5. Molecular epidemiology approach : nested case-control studies in glioma and lymphoid malignancies

   Författare :Florentin Späth; Beatrice S. Melin; Carl Wibom; Ann Sofie Johansson; Ingvar Bergdahl; Ola Landgren; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; B cell lymphoma; multiple myeloma; risk; repeated samples; prospective longitudinal study; nested case-control study; circulating sEGFR and sERBB2; circulating immune markers and growth factors; marker disease association; disease progression; NSHDS; Janus; linear mixed modeling; epidemiologi; Epidemiology; Oncology; onkologi;

   Sammanfattning : BACKGROUND: Nested case-control studies aim to link molecular markers with a certain outcome. Repeated prediagnostic samples may improve the evaluation of marker-disease associations. However, data regarding the benefit of repeated samples in such studies are sparse. LÄS MER
