1. 1. Pathway analysis: methods and perspectives

   Författare :Gustavo Stolf Jeuken; Lukas Käll; Mika Gustafsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pathway analysis; mutual information; survival analysis; enrichment analysis; transcriptomics.; Biotechnology; Bioteknologi;

   Sammanfattning : The amount of data being generated by high throughput molecular biology experiments grows every day, both in quantity and quality. With this comes the desire to have more powerful and comprehensive methods for statistical analysis that have been developed with the nature of this data in mind. LÄS MER

3. 2. Global functional association network inference and crosstalk analysis for pathway annotation

   Författare :Christoph Ogris; Erik Sonnhammer; Alfonso Valencia; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological networks; genome wide functional association networks; global gene association networks; gene networks; protein networks; functional association; functional coupling; network biology pathway analysis; pathway annotation; pathway enrichment; network-based enrichment; enrichment; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

   Sammanfattning : Cell functions are steered by complex interactions of gene products, like forming a temporary or stable complex, altering gene expression or catalyzing a reaction. Mapping these interactions is the key in understanding biological processes and therefore is the focus of numerous experiments and studies. LÄS MER

4. 3. Improved methods for enrichment of organic ultra trace components for analysis by gas chromatography

   Författare :Adam Kloskowski; KTH; []
   Nyckelord :water analysis; gas analysis; environmental analysis; sorbent trapping; organic traces; SPME; OTT;

   Sammanfattning : This thesis describes some new methods for analysis oforganic trace components from air and water by gaschromatography. The work is particularly focused on thedevelopment of new technologies for analyte enrichment, usingsorbent-based concepts. Short lengths of open tubular columnswere examined for their potential use as denuders. LÄS MER

5. 4. Non-porous membrane extractions in contemporary analysis

   Författare :Jan Norberg; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; extracting syringe; micro-porous membrane extraction; supported liquid membrane; solvent free; selectivity; clean-up; enrichment; Sample preparation; automation; Analytical chemistry; Analytisk kemi;

   Sammanfattning : To meet the desirable characteristic for sample preparation in contemporary, i. e. automation, high enrichment, clean-up, selectivity and essential solvent free techniques, the use of non-porous membrane extraction techniques is addressed. LÄS MER

7. 5. Analysis of tracer molecules from organic aerosols - Application of liquid phase microextraction to aerosol analysis

   Författare :Murtaza Hyder; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Liquid membrane extraction; Secondary organic aerosols; Enrichment; Tracers; Hollow fiber liquid phase microextraction; Biomass burning; Organic carbon;

   Sammanfattning : Airborne particulate matter is well known because of its adverse impacts on human health and its role in climate processes. In order to understand completely the role of aerosols in atmosphere, their chemical composition is of basic importance. LÄS MER
