  2. 1. Droplet microfluidics for directed evolution of biocatalysts

    Author : Staffan Sjöström; Helene Andersson Svahn; Florian Hollfelder; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Droplet microfluidics; Enzymes; directed evolution; high throughput screening; Bioteknologi; Biotechnology;

    Abstract : Biocatalysts, biologically derived catalysts, are of great importance for a wide range of industrial applications. They are used in the production of for example foods, pharmaceuticals and biofuels. Improving biocatalysts commonly relies on directed evolution, i.e. READ MORE

  4. 2. Evaluating effects of low concentrations of oil in marine benthic communities

    Author : Fredrik Lindgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PAHs; community response; microbial community; oil; meiofauna;

    Abstract : Large anthropogenic discharges of oil annually enter the marine environment, in the magnitude from large scale discharges to minor leakage, caused by ship collision accidents or seepage from urban areas. Possible detrimental environmental effects from these discharges differ, from acute lethal to chronic sub-lethal. READ MORE

  5. 3. The return of the nucleus : epigenetic regulation of autophagy

    Author : Jens Füllgrabe; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Autophagy is an evolutionary conserved catabolic process activated in response to a variety of cellular stresses, for example nutrient deprivation or chemotherapy. During autophagy, cells engulf parts of their cytplasm in a double-membrane vesicle, where misfolded proteins or damaged organelles are degraded. READ MORE

  6. 4. Screening for Atherosclerosis with Magnetic Resonance Imaging and Ultrasound

    Author : Christina Lundberg; Lars Johansson; Håkan Ahlström; Lars Lind; Anders Wanhainen; Hansen Tomas; Kenneth Caidahl; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Atherosclerosis is a major cause of death and disability worldwide. Although traditional risk factors can identify the healthy or severely affected individuals, sudden lethal outcome is still frequent in those suggested as intermediate in risk for cardiovascular events (CVE).

  7. 5. Analysis of Secondary Metabolites from Aspergillus fumigatus and Penicillium nalgiovense : Antimicrobial Compounds from Filamentous Fungi Isolated from Extreme Environments

    Author : Stefan Svahn; Lars Bohlin; Björn Olsen; Ulf Göransson; Erja Chryssanthou; Douglas Kinghorn; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aspergillus fumigatus; Penicillium nalgiovense; secondary metabolites; invasive aspergillosis; elicitation; gliotoxin; bis methyl gliotoxin; amphotericin B; Pharmacognosy; Farmakognosi;

    Abstract : This thesis describes the cultivation and extraction of filamentous fungi isolated from extreme environments in the search for new antibiotic compounds. Filamentous fungi are a rich source of medicines including antibiotics, and it is believed that many currently unknown fungal species and bioactive fungal metabolites remain to be discovered.
