Administering drug formulations to the vagina is a challenge since the vagina possesses “self-cleaning” features which allow trapping and rapid removing of foreign particles. Therefore, the residence time of drugs is often too short to offer a sufficient clinical effect. The aim of this project was to develop and optimize a liposomes-in-hydrogel system containing resveratrol for the local treatment ...

Background: Clinical studies have reported overexpression of PDE5 and elevation of intracellular cyclic GMP in various types of cancer cells. ABCC5 transports intracellular cGMP out of the cells with high affinity, while PDE5 inhibitors prevent high affinity cGMP efflux by inhibiting ABCC5. Increasing intracellular cGMP levels through inhibition of PDE5 and PDE5 export activity is hypothesized ...

In the recent years, governmental institutions have given incentives to the pharmaceutical industry in order to develop age-appropriate dosage forms for pediatric use. This has resulted in an interest in design of new and improved dosage form for pediatric patients. One of the many recent approaches is to take advantages of ODFs. Taste masking is a crucial step in the design of not only ODFs but all ...

Newly discovered compounds through bioprospecting are screened for cytotoxicity, and many of them are found to be highly toxic. Because they are often not specifically toxic only against cancer cells, they are not further studied. These new compounds could be of further interest by temporarily masking a functional group which regulate the anticancer activity of a cytotoxic compound. This means that ...

Oxytocin has been shown to be implicated in psychiatric diseases such as depression, anxiety disorders, autism post-traumatic stress disorder, and schizophrenia. As a result, oxytocin can be used as a potential treatment for these brain disorders. However, oxytocin is a large peptide, and is therefore unable to cross the blood brain barrier. Thus, the development of new small non-peptide drugs would ...

Chronic wounds are today representing a major challenge in global healthcare due the difficulty to treat as well as the costs for the society. Therefore, improving chronic wound therapy is an urgent need. Curcumin, a polyphenol compound, has shown to have potential in wound therapy due to its anti-inflammatory, anti-infectious and anti-oxidant properties. However, the poor water solubility, low ...

Background: Mass spectrometry-based proteomics has increasingly been the choice of method for the global analysis of the composition, modification and dynamics of proteins. Quantitative analysis of the proteome with tandem mass tag is a technique for calculating the relative abundance of the proteome in tissues and organelles. In this thesis, present a novel bottom-up method for the quantitative ...

Summary Elevated serum cholesterol blood levels is one of the central risk factors for cardiovascular diseases. Lowering blood cholesterol have significant impact on lowering cardiovascular disease events. Inhibiting cholesterol absorption in small intestine can significantly lower serum cholesterol levels and thereby - lower cardiovascular events. Β-cyclodextrin (βCD)-dextran polymer is expected ...

Bacterial natural products have contributed with a large part of the bioactive compounds that lead to drugs, and the biggest portion of the marketed antibiotics are bacterial products or their derivatives. Marine bacteria are not yet investigated to the same extend as their terrestrial counterparts. Therefore, they are considered a promising source for novel bioactive metabolites for drug development, ...

BAKGRUNN: Naltrekson er en ikke-selektiv opioidantagonist som tradisjonelt brukes til å behandle opioid- og alkoholavhengighet. Lavdose naltrekson (LDN), 3-5 mg/dag, har senere blitt brukt som «off-label» tilleggsbehandling i flere autoimmune sykdommer, inkludert kronisk inflammatorisk tarmsykdom (IBD). FORMÅL: Formålet med denne studien er å undersøke om det er en assosiasjon mellom bruk av LDN og ...
