  1. 1. The p97 ATPase and the Drosophila Proteasome : Protein Unfolding and Regulation

    Author : Kristian Björk Grimberg; Patrick Young; Neus Visa; Lars Thelander; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; proteasome; ubiquitin; p97; unfolding; regulation; RNAi screen; high-throughput screen; cnc; basic leucine zipper; transcription factors; proteasome inhibition; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : For all living systems, there is a requirement to recycle and regulate proteins. In eukaryotic organisms this is accomplished by the proteasome. The p97 ATPase is another highly conserved and essential complex present throughout the eukaryotic cell. READ MORE

  2. 2. Protein dynamics: aggregation and mechanical unfolding

    Author : Simon Mitternacht; Beräkningsbiologi och biologisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo simulations; All-atom protein models; Mechanical unfolding; Protein aggregation;

    Abstract : The subject of this thesis is protein dynamics. Papers I--IV and VI study either of two different processes: mechanical unfolding and aggregation. Paper V presents a computationally efficient all-atom model for proteins, variants of which are used to perform Monte Carlo simulations in the other papers. READ MORE

  3. 3. Design Space Exploration of Digital Circuits for Ultra-low Energy Dissipation

    Author : Syed Muhammad Yasser Sherazi; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; ultra low-voltage; ultra low-energy; subthreshold sub-VT ; body biasing; pipelining; unfolding; half-band digital filter.;

    Abstract : The ever expanding market of ultra portable electronic products is compelling the designer to invest major efforts in the development of small and low energy electronic devices. The driving force and benefactors of such devices are (but not limited to) e-health system, sensor network applications, security systems, environmental applications, and home automation systems.

  4. 4. Construction of force measuring optical tweezers instrumentation and investigations of biophysical properties of bacterial adhesion organelles

    Author : Magnus Andersson; Ove Axner; Lene Broeng Oddershede; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; optical tweezers; biological physics; unfolding; Escherichia coli; force measurements; energy landscape; dynamic force spectroscopy; manipulation; polymers; pili; Physics; Fysik;

    Abstract : Optical tweezers are a technique in which microscopic-sized particles, including living cells and bacteria, can be non-intrusively trapped with high accuracy solely using focused light. The technique has therefore become a powerful tool in the field of biophysics. READ MORE

  5. 5. SOD1 Aggregation : Relevance of thermodynamic stability

    Author : Lisa Lang; Mikael Oliveberg; Michele Vendruscolo; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Aggregation; misfolding; Superoxide dismutase SOD1 ; Amyotrophic lateral sclerosis ALS ; unfolding; thermodynamic stability; biokemi; Biochemistry;

    Abstract : Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease affecting the upper and lower motor neurons causing muscle atrophy and paralysis followed by death. Aggregates containing superoxide dismutase (SOD1) are found as pathological hallmark in diseased ALS patients. READ MORE
