  1. 6. How Substances in Agricultural Waste Material Can Be Used as Active Ingredients in Skin Care Products

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Lisa Prawitz; [2020]
    Nyckelord :Cosmetics; Skin care; Active substances; Agriculture; Skin aging; Pharmaceutical technology; Läkemedelsteknologi; Technology and Engineering;

    Sammanfattning : Aging of the skin is an inevitable process that occurs throughout a lifetime and exposure to environmental pollutants is a factor accelerating this process. Phytochemicals present in plants possess biological activities known to protect or repair the skin cells and when used in skin care products they can slow down the skin aging process. LÄS MER

    Sammanfattning : It is well known that Carbon monoxide is a toxic and hazardous gas, but during recent years it has been proven that using a controlled concentration, carbon monoxide can in fact be used as a therapeutic agent, and can contribute to decrease malaria, treat cardiovascular and lung diseases and potentially even treat cancer, among other things. The main problem in using carbon monoxide directly is the fact that it is not trivial to control the volume of gas inhaled, compromising its use as a therapeutic agent. LÄS MER

    Sammanfattning : Wood as a material has traditionally been used and is still used in many constructions in outdoor environments in Sweden. Despite the benefits of domestic materials that do not come from finite resources and have a special character, one cannot ignore the fact that wood requires maintenance. LÄS MER

  5. 9. Solljusinducerade hudskador och molekylära reparationssystem

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Sanna Persson; [2019]
    Nyckelord :;

    Sammanfattning : Ultraviolett (UV) strålning genererar fotodimerer i celler som leder till komplikationer med replikering och transkribering. Dessutom bidrar det också med DNA lesioner och brott. Förståelsen för hur de molekylära mekanismerna fungerar är av högsta vikt för att förhindra uppkomsten och bota hudsjukdomar som orsakats av UV-strålning. LÄS MER

  7. 10. Mapping of Bacteria with Flow Cytometry – before, during and after treatment of drinking water

    Master-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Mikael Danielsson; [2018]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : In order to produce drinking water of high quality, surface water works apply extensive treatment processes. In this study, flow cytometry and heterotrophic plate counting was utilized to study water quality before, during and after treatment in Görvälnverket in Stockholm, Sweden. LÄS MER
