Laktos – astmamedicinens bästa vän? Att leverera medicin till lungan är en krånglig process då en stor del av den verksamma substansen riskerar att fastna i svalget. Ny forskning har dock gett bredare förståelse för hur små partiklar av laktos kan användas till att öka effektiviteten hos inhalerbara läkemedel. Vid behandling av sjukdomar som drabbar luftvägarna, så som astma, finns det olika sätA common approach to treat respiratory diseases is with adhesive powder mixtures. These are dispersed into an aerosol upon inhalation. It has been found that the performance of such mixtures can be improved by adding fine particle lactose, but exactly why is yet to be established. Several theories have been proposed by previous studies, but the fundamental mechanism is still unknown. This study w

Att man kan använda röntgenstrålning för att ta bilder på kroppens inre har varit känt sedan sent 1800-tal och idag finns det en mängd olika röntgenapparater. En sådan är datortomografen, computed tomography (CT) på engelska. Med datortomografi är det möjligt att avbilda patienten i tre dimensioner, istället för vid slätröntgen där man endast får ut en tvådimensionell bild. Detta möjliggör en bättPurpose/Background Dual Energy Computed Tomography (DECT) have been clinically available for over ten years. Two such systems are currently used at Skane University Hospital (SUS) in Lund. By utilizing materials different attenuating properties at different energies, material decomposition and iodine quantification is possible. The aim of this master thesis was to compare the two DECT systems and

Små molekyler med stor inverkan - interferon alfas roll i Systemisk Lupus Erythematosus (SLE) Systemisk Lupus Erythematosus är en autoimmun sjukdom där immunförsvaret attackerar kroppens egna vävnader. Detta leder till en kronisk inflammation som kan yttra sig i en rad olika manifestationer beroende på var inflammationen sker. Sjukdomsaktiviteten går i perioder, dvs att den går upp i skov där patSystemic Lupus Erythematosus (SLE) is an autoimmune disease where the immune system is attacking the body and its tissues. This leads to a chronic inflammation that can affect different parts of the body and therefore present itself in a vast variety of symptoms. Depending on the activity of the disease it can go up in flares where the patients experience symptoms and then go down into recession.

Drygt femton miljoner människor avlider av cancer och stroke varje år, vilket gör dem till några av de svåraste sjukdomarna som vi drabbas av. Dödligheten hos dessa sjukdomar påverkas främst av när dem upptäcks. Ju tidigare sjukdomen diagnostiseras, desto högre blir sannolikheten för att den botas. Tidig upptäckt kräver känsliga diagnostiska metoder, särskilt de som kan detektera förändringar i väFifteen million people lose their lives to stroke and cancer every year. This amounts to one in every four deaths worldwide, making these among the deadliest diseases affecting humankind. Fruitful attempts at containing stroke- and cancer-related mortality hinge on early detection. Diffusion MRI (dMRI) is an imaging modality that is sensitive to tissue microstructure, and therefore unveils tissue

These new stores have the intent of reducing waste by using, for instance, Circular Economy s

The Maha Oya river mouth, located on the west coast of Sri Lanka, is seasonally closed by a sand bar formed at the river mouth due to little rainfall and thus little river discharge. A new Outlet, located just north of the Maha Oya river mouth, was created by the 2004 tsunami. The Outlet remains open all year because of its location in the lee of an offshore breakwater. When the Maha Oya river mou

Elbehovet ökar och landbaserad solkraft lyfts fram som en lösning för att snabbt möta elektrifieringen, men när solparker planeras på jordbruksmark väcks debatten: mat eller el? En möjlig väg framåt är att upprätta solparker på lågproduktiv jordbruksmark och förvalta den som gräsmark för att främja kolinlagring. I den planerade solparken Kogshult, i Sjöbo kommun, undersöker denna studie solsambrukAs pressure on land-use increase due to climate change and a transition to fossil-free energy sources, there is a growing interest in the potential to combine agricultural activities with ground-mounted solar energy parks. While claiming agricultural land for energy production sparks a lot of debate, a potential compromise may lie in utilizing depleted agricultural land for solar farms, purposely

I övergången till en cirkulär ekonomi använder industrier i allt högre grad återvunnet material för att minska klimatpåverkan från sina produkter. Den ökade efterfrågan på återvunnet material drivs av både EU-direktiv och konsumenters preferenser.
