  1. 1. Effect of hydration on thermodynamic, rheological and structural properties of mucin

    Detta är en avhandling från Malmö University, Faculty of Health and Society

    Författare :Yana Znamenskaya; Malmö University.; Malmö University.; [2013]
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; PHARMACY; FARMACI; Technology; mucous gel; mucus; mucin; PGM; BSM; BSM chitosan multilayers; hydration; water sorption isotherm; relative humidity; water activity; bound water; enthalpy of hydration of biopolymer; glass transition; rheology; phase diagram; fiber-like structure; dumbbell-like structure; sorption calorimetry; DSC; QCM-D; SAXS; AFM;

    Sammanfattning : Mucus, an adherent hydrated layer covering the epithelium, is found in all internal tracts of the body and plays an important role in animal and human life. One of the essential functions of mucus is protection of tissues against dehydration. LÄS MER

  2. 2. Water and protein solutions studied by field-dependent magnetic relaxation

    Detta är en avhandling från Biophysical Chemistry (LTH), Lund University

    Författare :Kristofer Modig; Lunds universitet.; Lund University.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; relaxation; protein solvation; protein dynamics; protein denaturation; oxytocin; magnetic relaxation dispersion; nuclear magnetic resonance; lipid-binding protein; hydration; beta-lactoglobulin; BPTI; shielding anisotropy; water; Molecular biophysics; Molekylär biofysik;

    Sammanfattning : Popular Abstract in Swedish Kärnmagnetisk resonans (NMR) är en metod som bygger på att många atomkärnor uppför sig som mycket små magneter. Detta i sin tur beror på att kärnan beter sig som en liten roterande laddning. Man säger att kärnan har ett spinn, eller att kärnan är ett spinn. LÄS MER

  3. 3. Water transport through perinatal skin Barrier function and aquaporin water channels

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Johan Ågren; Uppsala universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Preterm infant; Transepidermal water loss; Aquaporin; Skin biology; Hyperosmolarity; Pediatrik; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Paediatric medicine; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Pediatrisk medicin; pediatrik; Pediatrics;

    Sammanfattning : While constituting a well functioning interface with the aqueous environment in utero, the skin offers a poor barrier after very preterm birth. As a result, transepidermal water loss (TEWL) is high, a fact which has important clinical consequences in these infants. LÄS MER

  4. 4. Protein-water interactions studied by molecular dynamics simulations

    Detta är en avhandling från Department of Chemistry, Lund University

    Författare :Filip Persson; Lunds universitet.; Lund University.; [2018-02-14]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MD simulations; NMR nuclear magnetic resonance ; MRD; water dynamics; protein dynamics; protein hydration; Amide hydrogen exchange; Internal water; compressibility;

    Sammanfattning : Most proteins have evolved to function optimally in aqueous environments, and the interactions between protein and water therefore play a fundamental role in the stability, dynamics, and function of proteins. Although we understand many details of water, we understand much less about the protein-water interface. LÄS MER

  5. 5. Aqueous Solutions as seen through an Electron Spectrometer Surface Structure, Hydration Motifs and Ultrafast Charge Delocalization Dynamics

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Niklas Ottosson; Uppsala universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Water; Aqueous solutions; Ions; Molecular Hydration; Electron dynamics; Atmospheric Chemistry; Hydrolysis; Acid-Base Chemistry; Interatomic Coulombic Decay; ICD; Liquid Micro-Jet; X-ray Photoelectron Spectroscopy; XPS; Auger Electron Spectroscopy; AES; MAX-lab; BESSY; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : In spite of their high abundance and importance, aqueous systems are enigmatic on the microscopic scale. In order to obtain information about their geometrical and electronic structure, simple aqueous solutions have been studied experimentally by photo- and Auger electron spectroscopy using the novel liquid micro-jet technique in conjunction with synchrotron radiation.
