  1. 1. Infrared spectroscopic studies : from small molecules to large

    Author : Nadejda Eremina; Andreas Barth; Silvia Maria Doglia; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Infrared spectroscopy; transcription factors; DNA; creatine kinase; CaATPase; water; ligand binding; biofarmaci; Biopharmaceutics;

    Abstract : Infrared light (IR) was first discovered by Friedrich Wilhelm Herschel in 1800. However, until 1940’s, molecular IR studies involved only water and small organic molecules, because of the long measurement times. READ MORE

  3. 3. Synchrotron Radiation Studies of Free and Adsorbed Molecules

    Author : Zhuo Bao; Maria Novella Piancastelli; Svante Svensson; Denis Ceolin; Edwin Kukk; Uppsala universitet; []
    Keywords : Physics; Synchrotron radiation; Auger electron spectroscopy; one-step model; Post Collision Interaction PCI ; theoretical modeling; molecules; adsorbates; UPS; XPS; XAS; NEXAFS; Fysik;

    Abstract : This thesis contains two parts. The first part concerns the research work on free molecules using synchrotron-radiation-related techniques. Auger electron spectra of two free open-shell molecules, O2 and NO, were studied experimentally and theoretically. READ MORE

  4. 4. Studies of mutant p53-targeting small molecules

    Author : Nicole Zache; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Multiple cellular stresses, such as DNA damage, oncogene activation, hypoxia, and telomere erosion induce p53 protein levels leading to an array of biological responses, including cell cycle arrest and apoptosis. p53 exerts its function mainly through transcriptional regulation of specific target genes, but is also able to induce transcriptional-independent apoptosis.

  5. 5. Mass Spectrometry of Biologically Active Small Molecules : Focusing on polyphenols, alkaloids and amino acids

    Author : Zdeněk Spáčil; Leopold L. Ilag; Frantisek Turecek; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; LC-MS; LDI; Mass spectrometry; HPLC; UHPLC; polyphenols; phenolic acids; BMAA; Separation methods; Separationsmetoder; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : The foci of this dissertation are on advanced liquid chromatography (LC) separation and mass spectrometry (MS) techniques for the analysis of small bioactive molecules. In addition to discussing general aspects of such techniques the results from analyses of polyphenols (PPs), alkaloids and amino acids published in five appended studies are presented and discussed.
