  1. 1. Mesoporous Silica SBA-15 - Formation, Modification and Application

    Author : Tomas Kjellman; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SBA-15; Mesoporous Silica; Intrawall pores; Colloidal Stability; Drug release; Deposition;

    Abstract : Several aspects related to the mesoporous silica material SBA-15 have been studied through the use of a wide range of experimental techniques, including low voltage high-resolution scanning electron microscopy, small angle X-ray scattering and nitrogen sorption. This work contains three parts, which are in many ways overlapping. READ MORE

  2. 2. Identification and Characterization of Peptides and Proteins using Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

    Author : Magnus Palmblad; Ole Nørregaard Jensen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Peptide; protein; peptide mass fingerprinting; identification; sequencing; protein structure; non-covalent interaction; modification; electrospray ionization; liquid chromatography; capillary electrophoresis; electron capture dissociation; Fourier transform ion cyclotron resonance mass spectrometry; cerebrospinal fluid; amyloid β-peptide; Alzheimer’s disease.; Materialvetenskap; Materials science; Teknisk materialvetenskap; Molecular Biotechnology; Molekylär bioteknik;

    Abstract : Mass spectrometry has in recent years been established as the standard method for protein identification and characterization in proteomics with excellent intrinsic sensitivity and specificity. Fourier transform ion cyclotron resonance is the mass spectrometric technique that provides the highest resolving power and mass accuracy, increasing the amount of information that can be obtained from complex samples.

  3. 3. CELL PENETRATING PEPTIDES : CHEMICAL MODIFICATION AND FORMULATION DEVELOPMENT

    Author : Kariem Ezzat; Ülo Langel; Astrid Gräslund; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Abstract : Cell penetrating peptides (CPPs) have been extensively studied and exploited as drug delivery vectors for a wide variety of therapeu-tic cargos. However, several issues remain to be addressed regarding the enhancement of their efficiency and stability. READ MORE

  4. 4. Levodopa- and Neuroleptic-Induced Dyskinesias : Studies on Pharmacological Modification and Processing of Opioid Neuropeptides

    Author : Rebecka Klintenberg; Alan Crossman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological research on drug dependence; Opioid peptides; dyskinesia; Parkinson s disease; mass spectrometry; metabolism; Biologisk beroendeforskning; Biological research on drug dependence; Biologisk beroendeforskning; biologisk beroendeforskning; Biological Research on Drug Dependence;

    Abstract : Dyskinesias or abnormal involuntary movements are a debilitating complication of long-term levodopa treatment of Parkinson’s disease (PD) that is widely experienced and may compromise the efficacy of the drug therapy. Tardive dyskinesia is another important adverse effect seen with antipsychotic drug treatment. READ MORE

  5. 5. Environment-Sensitive Multifunctional Drug Delivery Systems

    Author : Jian Qin; Mamoun Muhammed; Marcus Textor; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials chemistry; Materialkemi;

    Abstract : Drug delivery systems (DDS) with multiple functionalities such as environment-sensitive drug release mechanisms and visualization agents have motivated the biomedical community as well as materials chemists for more than a decade. This dissertation is concerned with the development of nanoparticles for multifunctional DDS  to tackle several crucial challenges in these complex systems, including polymeric nanospheres which respond to temperature change, superparamagnetic iron oxide nanoparticles/polymeric composite for magnetic resonance imaging contrast agents and drug carriers, immunoresponse of nanomaterials and injectable magnetic field sensitive ferrogels.
