  2. 1. Fullerene γ-Cyclodextrin Complexes

    Author : Thomas Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; C60; a-cyclodextrin; aggregates; FAB LSIMS; Buckminsterfullerene; g-cyclodextrin; b-cyclodextrin; ring-currents; fullerene; host-guest; C70;

    Abstract : The fullerenes, C60 and C70, can form inclusion complexes with .gamma.-cyclodextrin as the host. The complexes are formed by refluxing a water solution of . READ MORE

  4. 2. Investigations of New Biomimetic Transamination Systems and Inclusion Complexation with Cyclodextrins

    Author : Anders Hjelmencrantz; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stereochemis; bicyclooctanes.Transamination; complexation; cyclodextrins; proton transfer; hydride transfer; stereochemistry; Transamination; Organic chemistry; Organisk kemi;

    Abstract : Two new transamination systems are described. The first example is a dibenzo[a,d]- cycloheptene containing system, designed to accomplish a [1,3]-hydride transfer. Several catalysts have been examined for this purpose. tris-Pentafluorophenyl borane was found to be the most efficient catalyst. READ MORE

  5. 3. An alkaline active maltooligosaccharide forming alpha-amylase from Bacillus halodurans

    Author : Suhaila Hashim; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk teknik; Biochemical technology; differential scanning calorimetry; soda lakes; Bacillus halodurans; alkaliphile; á-amylase;

    Abstract : The East African Rift Valley contains a number of soda lakes, which represent some of the most stable, naturally occurring alkaline environments on earth. Alkaliphilic microorganisms found in these habitats have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values for industrial applications.

  6. 4. An Alkaline Active Cyclodextrin Glycosyltransferase from an Alkaliphilic Bacillus agaradhaerens

    Author : Rita Martins; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloning; characterization; purification; 16S rRNA gene analysis; screening; alkaliphiles; soda lakes; Bacillus agaradhaerens; cyclodextrins; cyclodextrin glycosyltransferase; alpha-amylase family; sequencing; immobilization; Biotechnology; Bioteknik;

    Abstract : Soda lakes represent the most stable naturally-occurring alkaline environments on Earth and harbour a diverse population of alkaliphiles. Alkaliphilic microorganisms have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values. READ MORE

  7. 5. Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery

    Author : Vladimir Kirejev; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photodynamic therapy; PDT enhancement; Nitric oxide; NO-based PDT; Targeted drug delivery; Galectin-3; mTHPP; Cyclodextrin; CD-mTHPP conjugate; PpIX AuNP combination; Two-photon microscopy; FLIM; Cell phototoxicity; Ex vivo skin;

    Abstract : The increasing incidences of cancer and related deaths call for the development of new and improved treatment modalities. Photodynamic therapy (PDT) today is an alternative to conventional treatments, but has limitations. This thesis explores different nanosystems with aim to improve PDT focusing on spectroscopic and ex vivo studies. READ MORE
