  1. 1. Development of nicotinic receptor ligands for positron emission tomography - from in vitro to in vivo : Binding studies of neuronal nicotinic acetylcholine receptors using different ³H-, ¹1C- and `6Br - labeled ligands

    Author : Wiebke Sihver; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; nicotinic acetylcholine receptor; PET-ligand; in vitro; in vivo; Alzheimer s disease; Neurovetenskap; Neurology; Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Abstract : Neuronal nicotinic acetylcholine receptors (nAChRs) are involved in central processes, such as cognitive functionand memory, and play a critical role in neuropathological changes in Alzheimer's disease (AD). The in vivocharacterization of nAChRs by positron emission tomography (PET) may increase our understanding of thefunctional implications of these receptors in AD and their early changes during this disease.

    Author : Patric Wallin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell migration; lipid bilayers; cell differentiation; liquid handling; surface functionalization; Microfluidics; chemotractant gradients; mammalian cell culture; cell microenvironments; in vitro screening assay;

    Abstract : Stem cells have a great potential to bring about advancements in fields like developmental biology, drug discovery, cancer biology and tissue engineering. In order to be able to use stem cells to their full potential, it is important to have control over their behavior. READ MORE

  3. 3. Protein–DNA Recognition : In Vitro Evolution and Characterization of DNA-Binding Proteins

    Author : Mikael Nilsson; Mikael Widersten; Dan Tawfik; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; In vitro evolution; Phage display; mRNA display; Cro; DNA recognition; repressor; Biokemi; Biochemistry; Biokemi;

    Abstract : DNA-recognizing proteins are involved in a multitude of important life-processes. Therefore, it is of great interest to understand the underlying mechanisms that set the rules for sequence specific protein–DNA interactions. Previous attempts aiming to resolve these interactions have been focused on naturally occurring systems. READ MORE

  4. 4. In vitro characterization of nanodrugs at model lipid membranes

    Author : Rickard Frost; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; in vitro screening; nanomedicine; drug delivery; drug carrier; supported lipid bilayer; QCM-D; nanoparticle; cell membrane;

    Abstract : The use of nano-sized drug carriers to improve the efficiency of drug delivery has become well established during the past decades. New nanoparticle (NP) formulations for the administration of biopharmaceuticals (e.g. proteins and peptides) emerge at an increasing rate and the need for methods to evaluate their properties is expanding.

  5. 5. Development and characterization of an in vitro method for interaction studies between polymers and pharmaceuticals : Aiding in the development of new drug delivery systems

    Author : Marcus Wanselius; Per Hansson; Magnus Bergström; Susanna Abrahmsén-Alami; Christian Pedersen; Anna Fureby; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microgels; Subcutaneous administration; Drug delivery; Microfluidics; In vitro methodology; Method development; Biopharmaceuticals; Amphiphilic drugs; Polyelectrolytes; Hyaluronic acid; Peptides; Farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

    Abstract : Polymers are a group of macromolecules used in formulations of pharmaceuticals, one example being the delivery system DC Bead™. Further, some of the most abundant and for drug delivery important constituents of the subcutaneous tissue are charged polymers (polyelectrolytes), e.g. collagen, hyaluronic acid, and chondroitin sulfate.
