  2. 1. Interplay between Transcription and Homologous Recombination in the Presence of DNA Damage

    Author : Ivaylo Stoimenov; Thomas Helleday; Niklas Schultz; Natalia Issaeva; Thierry Nouspikel; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; homologous recombination; transcription; DRB; UVC; 6-thioguanine; mammalian cells; BRCA1; BRCA2; PARP inhibitors; XP-V; Molecular biology; Molekylärbiologi; molekylärgenetik; Molecular Genetics;

    Abstract : The biochemical processes of DNA repair, replication and recombination compete for the same substrate, the DNA molecule. This competition is natural, as each process requires the same template. In order to resolve possible conflicts between these processes, when they take place on a particular stretch of DNA, certain crosstalk is expected. READ MORE

  4. 2. Epitaxial III-V/Si heterojunctions for photonic devices

    Author : Giriprasanth Omanakuttan; Sebastian Lourdudoss; Yanting Sun; Harri Lipsanen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epitaxy; heterojunction; III-V on Si integration; solar cell; Fysik; Physics;

    Abstract : Monolithic integration of III-V materials on silicon is of great interest for efficient electronic-photonic integrated devices and multijunction solar cells on silicon. However, defect formation in the heteroepitaxial layers due to lattice mismatch, thermal mismatch, and polarity mismatch makes it a great challenge. READ MORE

  5. 3. Cellular Aspects of Lignin Biosynthesis in Xylem Vessels of Zinnia and Arabidopsis

    Author : Henrik Serk; Edouard Pesquet; Simon Hawkins; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lignin; tracheary elements; xylem wood; post-mortem lignification; non-cell autonomous process; xylem parenchyma; endoreplication; reactive oxygen species; laccases; peroxidases; molecular cell biology; molekylär cellbiologi;

    Abstract : Lignin is the second most abundant biopolymer on earth and is found in the wood (xylem) of vascular land plants. To transport the hydro-mineral sap, xylem forms specialized conduit cells, called tracheary elements (TEs), which are hollow dead cylinders reinforced with lateral secondary cell walls (SCW).

  6. 4. Glycerol kinase deficiency. Clinical, biochemical, and genetic aspects

    Author : Christina Hellerud; Göteborgs universitet; []
    Keywords : contiguous gene syndrome; diagnose; exercise; fasting; glucose deficit; glycerol; glycerol kinase deficiency; metabolism; molecular modelling; mRNA analysis; mutation; natural history; prognosis; splice-junction analysis; treatment; triglycerides;

    Abstract : Glycerol kinase deficiency (GKD, MIM 307030) is an X-linked recessive inborn error of metabolism occurring isolated or in an Xp contiguous gene syndrome with adrenal hypoplasia and/or Duchenne muscular dystrophy. The gene syndrome is due to deletions in the p21 region on the X chromosome. READ MORE

  7. 5. Doping of Semiconductor Nanowires

    Author : Jesper Wallentin; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal-organic vapour phase epitaxy; III-V semiconductor materials; nanowires; doping; solar cells; F:2013:Wallentin;

    Abstract : In this thesis, in situ doping during growth of III-V semiconductor nanowires, primarily for photovoltaic applications, is investigated. The nanowires were grown by metalorganic vapor phase epitaxy (MOVPE), with gold seed particles. READ MORE
