  1. 11. On Carbohydrate Intake and Dental Status in the Elderly

    Författare :Torgny Alstad; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carbohydrates; Cohort analysis; Dental caries; Dental status; Elderly; Epidemiology; Factor analysis; Graphic interaction model; Oral sugar clearance;

    Sammanfattning : People?s dental status has the potential to affect dietary intake and, at the same time, diet may affect the health of the dentition. To study the associations, the elderly appear to be an appropriate group and carbohydrates the appropriate nutrients. LÄS MER

  3. 12. Derivatising Carbohydrates for Biological Applications

    Författare :Anders Bergh; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Carbohydrates have a wide variety of functions in Nature. The somewhat old view of carbohydrates only functioning as building blocks or energy sources, has been overturned by the newer insight that carbohydrates are deeply involved in recognition processes, such as receptors for bacteria, viruses, antibodies and proteins.

  4. 13. Carbohydrate-specific, boronate-containing copolymers: from sugar-sensing to cell adhesion

    Författare :Marina Kuzimenkova; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface grafting; chemisorption; boronic acid; carbohydrates; affinity; chromatography; smart polymers; biomimetics; hydrogels; molecular recognition; diffusion; sugar-sensing; cell adhesion;

    Sammanfattning : Carbohydrates play a major role in many cell recognition events and metabolic pathways of living organisms. Synthetic carbohydrate receptors are of great interest for the chemical design of sugar sensors, materials for cell separation, cell immobilization, drug delivery and other biomedical/biotechnological applications.

  5. 14. Synthesis of biologically active oligosaccharides of the Lewis b family and investigations towards the synthesis of glycoclusters

    Författare :Linnéa Skantz; Martina Lahmann; Thisbe Lindhorst; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Lewis b; lactosamine; dendrimers; oxazolidinone; Organic synthesis; Organisk syntes; organisk kemi; Organic Chemistry;

    Sammanfattning : The gastric pathogen Helicobacter pylori is a Gram negative bacterium which may cause diseases such as peptic ulceration and gastric adenocarcinoma. It colonises a host by attaching to the gastric epithelial cells, an attachment mediated by outer membrane proteins on the bacterial surface, e.g, the blood group antigen binding adhesin, BabA.

  7. 15. Computer-Assisted Carbohydrate Structural Studies and Drug Discovery

    Författare :Magnus Lundborg; Göran Widmalm; Hans-Christian Siebert; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; molecular docking; molecular dynamics simulation; fragment-based virtual screening; NMR spectroscopy; computer-aided drug design; computer-aided structure elucidation; glycosyltransferases; Escherichia coli; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : Carbohydrates are abundant in nature and have functions ranging from energy storage to acting as structural components. Analysis of carbohydrate structures is important and can be used for, for instance, clinical diagnosis of diseases as well as in bacterial studies. The complexity of glycans makes it difficult to determine their structures. LÄS MER
