1. 1. Digital Electrical DNA Sensing

   Författare :Maoxiang Guo; Wouter van der Wijngaart; Fredrik Westerlund; KTH; []
   Nyckelord :DNA detection; thiol-ene-epoxy; rolling circle amplification; digital measurement; DNA stretching; microwell-array; gold nanowires; electrical measurement; specificity; limit of detection; liquid storage; disease diagnosis; lab-on-a-chip; point-of-care.;

   Sammanfattning : Molecule detection is a workhorse in life sciences and medicine, for example in cancer diagnosis and virus and bacterial detection. DNA analysis can provide vital information about the state of a host organism and its medical and health condition. LÄS MER

3. 2. Initiation of herpes simplex virus DNA replication

   Författare :Stina Simonsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; initiation of DNA replication; origin binding protein; Herpes Simplex Virus;

   Sammanfattning : During virus infection multiple new copies of the virus genome are made by a DNA synthesis machinery. Initiation of DNA replication involves the recognition of origins of DNA replication by an initiator protein. LÄS MER

4. 3. Herpes Simplex Virus 1 DNA replication and its role in recombination and transcription

   Författare :Ka-Wei Tang; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Herpes Simplex Virus 1; DNA replication; DNA recombination; Transcription;

   Sammanfattning : Herpes simplex virus 1 (HSV-1) is one of nine different herpesvirus infecting man. They are all capable of establishing a life-long latent state following the primary infection. HSV-1 as well as other herpesviruses may reactivate from the latent state and give rise to a productive infection with clinical symptoms or asymptomatic shedding. LÄS MER

5. 4. DNA-Controlled Lipid-Membrane Fusion

   Författare :Lisa Simonsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; exocytosis; vesicles; DNA; FRET; fluorescence resonance energy transfer; model system; total internal reflection fluorescence microscopy; TIRF microscopy; self-assembly; site-specificity; diffusion; biomembranes; lipid bilayer; membrane fusion;

   Sammanfattning : Membrane fusion is essential for nerve-cell communication, for protein transport between cell organelles and the cell-membrane and for enabling the merger between virus and host membranes during virus infection. We have demonstrated that short DNA oligonucleotides, membrane-attached via CH in an orientation that mimics the overall zipperlike architecture of fusion-inducing proteins, induce fusion of both suspended vesicles and vesicles site-specifically tethered to SLBs.

7. 5. Initiation of bacteriophage P2 rolling circle replication

   Författare :Richard Odegrip; Barbara Funnel; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Virus; DNA; Genetics; genetik;

   Sammanfattning : Viruses are very simple entities. In its most simple form, the virus consists of a protein shell containing genetic material. To propagate the virus needs a host to parasitize, in which it can replicate its genetic material and assembly new virus particles. Viruses that parasitize bacteria are termed bacteriophages. LÄS MER
