    Abstract : Hereditary ichthyosis is a collective name for many dry and scaly skin disorders ranging in frequency from common to very rare. The main groups are autosomal recessive lamellar ichthyosis, autosomal dominant epidermolytic hyperkeratosis and ichthyosis vulgaris, and x-linked recessive ichthyosis. READ MORE

    Abstract : The skin is a barrier which protects us against daily attacks of foreign substances. From a pharmaceutical perspective it is also an interesting delivery route with its large surface and possibility to reach the blood stream circumventing first passage metabolism. With the varied size, structure etc. READ MORE

  3. 3. PEG and lipids in solid dispersions and liquid crystals - structure and phase behaviour

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan Unga; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bicontinuous sponge phase; polyethylene glycol; monoolein; bicontinuous cubic phase; lipids; differential scanning calorimetry; phytantriol; small angle X-ray diffraction; solid dispersions;

    Abstract : In this thesis, two different kinds of nano-structured systems have been studied; solid dispersion systems of polyethylene glycol (PEG) and liquid crystalline systems containing the polar lipids monoolein (MO) and phytantriol (PT). Solid dispersions of PEG were studied with addition of different substances, lipids or parabens. READ MORE

  4. 4. Lactic acid production: extractive fermentation in aqueous two-phase systems

    University dissertation from Department of Applied Microbiology, Lund University

    Author : Jordi Planes; Lund University.; Lunds universitet.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gel excludion chromatography; polyethylenimine; ethylene oxide propylene oxide; phase forming polymers; aqueous two-phase systems; extractive fermentation; Lactococcus; Lactobacillus; Mikrobiologi; bakteriologi; virologi; mykologi; bacteriology; virology; mycology; Microbiology;

    Abstract : There is an increased interest in the microbial production of lactic acid as a raw material for the synthesis of lactic acid polymers as biodegradable plastics. However, two factors limit the economical competitiveness of lactic acid production by microorganisms: lactic acid inhibition, which decreases both fermentation rate and the maximum lactic acid concentration, and the efficiency in the recovery of lactic acid.

  5. 5. Electrolyte structures and ionization conditions for iontophoretic drug formulation of local anesthetics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Abstract : Iontophoresis is a modern method of drug delivery by which charged bioactive molecules (drugs) are transferred from an electrolytic reservoir into and through a tissue, normally skin, by means of a weak electric current. The drug is placed in a conductive medium, usually an aqueous solution or a hydrogel, between the "active" electrode and the skin. READ MORE
