    Abstract : The CIS solar cell family features both a high stability and world-class performances. They can be deposited on a wide variety of substrates and absorb the entire solar spectrum only using a thickness of a few micrometers. READ MORE

  2. 2. Ras-MAPK signaling in differentiating SH-SY5Y human neuroblastoma cells

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna-Karin Olsson; [2000]

    Abstract : Neuroblastoma is a malignant childhood cancer, originating from sympathetic neuroblasts of the peripheral nervous system. Neuroblastoma is a heterogenous group of tumours, while some are highly malignant others can spontaneosly mature into a more benign form or regress. READ MORE

  3. 3. Cell fate specification by Ras-mediated cell signalling in C. elegans

    University dissertation from Umeå : Umeå centrum för molekylär patogenes (UCMP) (Medicinska fakulteten)

    Author : Teresa Tiensuu; Simon Tuck; Benjamin Podbilewicz; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; cell signalling; Ras; vulva precursor cell; lin-25; sur-2; lin-1; cell fate specification; Mediator; vulva induction; transcriptional regulation; Cell- och molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi;

    Abstract : Induction of vulval fates in the C. elegans hermaphrodite is mediated by a conserved RTK/Ras/MAP kinase signalling pathway, in which the core components can be placed into a linear genetic and biochemical pathway. However, the events that occur downstream of this pathway are not yet well understood. READ MORE

  4. 4. Study of Resistance in Hepatitis C Virus Prior to Treatment with Direct Acting Antivirals

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Midori Kjellin; Johan Lennerstrand; Nina Weis; [2020]

    Abstract : The rapid advancement of Hepatitis C (HCV) treatment presents a great challenge to clinicians in optimising therapy for their patients. Genotype (GT), efficacy, side-effects, drug combinations and treatment durations must be tailored to individual patients, considering comorbidities, degree of fibrosis, adherence and antiviral resistance.

  5. 5. Exoenzyme S of Pseudomonas aeruginosa cellular targets and interaction with 14-3-3

    University dissertation from Umeå : Medicinsk biovetenskap

    Author : Lubna Yasmin; Bengt Hallberg; Joan Olson; [2007]

    Abstract : Pseudomonas aeruginosa is an opportunistic pathogen that is a serious problem for immuno-compromised patients. Toxins such as exoenzyme (Exo) S, ExoT, ExoY and ExoU are secreted and translocated from the bacteria into the eukaryotic cell via the bacterial encoded type III secretion system. READ MORE
