  1. 1. Humectants and skin : effects of hydration from molecule to man

    Författare :Cathrine Albèr; Malmö högskola; []
    Nyckelord :skin; stratum corneum; hydration; hyaluronan; glycerol; urea;

    Sammanfattning : Humectants belong to a group of hydrophilic compounds frequently used in skin care products with the aim to diminish the clinical symptom of skin dryness. The biochemical and biophysical mechanisms by which humectants interact with the skin barrier are far from fully understood. LÄS MER

    Sammanfattning : Tactile perception is considered an important contributor to the overall consumer experience of a product. However, what physical properties that create the specifics of tactile perception, are still not completely understood. LÄS MER

  4. 3. Tactile Perception - Role of Physical Properties

    Författare :Lisa Skedung; Mark Rutland; Katrin Danerlöv; Sören Andersson; Ann Maria Cornell; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Finger Friction; Skin Friction; Paper Friction; Friction Coefficient; Piezoelectric Force Sensor; Skin Tribology; Biotribology; Soft Tribology; Surface Roughness; Profilometry; Coated Paper; Uncoated Paper; Printing Paper; Magazine Paper; Tactile Perception; Psychophysics; Multidimensional Scaling; Magnitude Estimation; Paper Coarseness; Thermal Conductivity; X-ray Photoelectron Spectroscopy.; Chemistry; Kemi;

    Sammanfattning : The aim of this thesis is to interconnect human tactile perception with various physical properties of materials. Tactile perception necessitates contact and relative motion between the skin and the surfaces of interest. LÄS MER

  5. 4. Host-bacterium relationship in staphylococcal skin infection

    Författare :Lena Mölne; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Staphylococcus aureus; skin; mice; superantigen; TSST-1; neutrophils; gamma delta T cells; bacterial DNA; CpG ODN;

    Sammanfattning : Skin infections caused by Staphylococcus aureus are commonly occuring, both in the community and in hospitals. Despite the high prevalence of this condition, little is known about the host immune responsiveness and bacterial virulence factors during S. aureus skin infection. LÄS MER

  7. 5. Topical formulations, design and drug delivery : "A dive into water"

    Författare :Abdullah Ali; Marie Lodén; Anan Yagmur; Anders Hall; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; water; topical formulations; Pickering emulsion; skin cream; drug delivery; tactile friction; sensory panel; nasal; buccal; mucosa; skin; triglycerides; ethanol; drug transport; cosmetic appeal;

    Sammanfattning : Water is a vital component regulating the properties of topical formulations and their interaction with biological barriers, such as skin and mucosa. Changing the watercontent within the frame of the pharmaceutical triangle will have a huge impact on which type of formulation, such as a cream, ointment, gel, or lotion, is formed, as well as the physical properties of the formulation.
