  2. 1. Borderline patients in group psychotherapy : studies in process and outcome

    Author : Dan Stiwne; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; group psychotherapy; borderline patients; therapy drop-out; group psychotherapy outcome; therapist interventions;

    Abstract : Group psychotherapy with borderline patients is an activity that is fraught with ominous apprehension and it is perhaps for this reason that little research has been done in the field. The aim of the present studies was to map out the area and to test some basic hypotheses about patient and therapist behaviour during the therapy process. READ MORE

  4. 2. Organic Heavy Group 14 Element Compounds : A Study of Their Chemical Bonding Properties Directed Towards Applications as Molecular Wires and in Synthesis

    Author : Julius Tibbelin; Henrik Ottosson; Christoph Marschner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silicon; Group 14 Elements; Silenes; Conjugation; Chemical Bonding; Electronic Structure; Protecting Group Chemistry; Physical organic chemistry; Fysikalisk organisk kemi; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : The research described herein includes synthesis, spectroscopy, and quantum chemical calculations with focus on the characteristic properties of compounds with bonds between carbon and the heavier Group 14 elements.The chapters based on the first four papers concern σ- and σ/π-conjugated compounds, although the focus of the first paper is on ring strain of bicyclo[1.

  5. 3. Glycoconjugates : synthesis and investigation of carbohydrate-protein interactions

    Author : Sara Spjut; Mikael Elofsson; Ulf Ellervik; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Glycoconjugates; Carbohydrates; Galactose; Glucose; Solid-phase synthesis; SPOS; Glycosylation; Gel-phase 19F NMR spectroscopy; Fluorinated linker; Carbohydrate array; Microtiter plates; Carbohydrate-protein interactions; carbamate linker; Fsec; Protecting group; Fluorinated protecting group; Multivalent glycoconjugates; Adenovirus; Ad37; Epidemic keratoconjunctivitis; EKC; Sialic acid; Adenovirus inhibitor; Trivalent; Tetravalent; X-ray crystal structure; Bioorganic chemistry; Bioorganisk kemi; organisk kemi; Organic Chemistry;

    Abstract : To study the functions of glycoconjugates in biological systems reliable and efficient protocols for glycoconjugate synthesis are needed. To reach this goal we have developed methods for solid-phase synthesis of glycoconjugates that can be monitored with gel-phase 19F spectroscopy using fluorinated linkers, building blocks, and protecting groups.

  6. 4. Novel Methods for Synthesis of High Quality Oligonucleotides

    Author : Andrey Semenyuk; Marek Kwiatkowski; Ulf Landegren; Joachim W. Engels; Uppsala universitet; []
    Keywords : Organic chemistry; oligonucleotide; solid-phase synthesis; RNA synthesis; phosphoramidite; abasic sites; depurination; 2 -O-DTM; protecting group; cartridge; conjugate; dithiomethyl linker; base-stable linker; oligonucleotide purification; nucleoside; Organisk kemi;

    Abstract : The first part of the work describes a procedure of oligonucleotide purification using a reversed-phase cartridge. The developed method employs a very efficient yet mild oligonucleotide detritylation on the cartridge support allowing fast purification of oligonucleotides regardless of their 5´-modification.
