1. Microfluidic sorting of sperm for assisted reproduction - An evaluation of ZyMōt multi sperm separation device
Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskapSammanfattning : Infertility is a worldwide problem and the main reason for the use of assisted reproductive technol- ogy (ART). In-vitro fertilization (IVF) is one ART treatment normally used, where the fertilization of oocytes occurs in vitro. LÄS MER
2. Design, expression and purification of virus-like particles derived from metagenomic studies : Virus-like Particles (VLP) of novel Partitiviridae species, Hubei.PLV 11, and novel Soutern pygmy squid flavilike virus were designed, expressed using the bac-to-bac expression system and then pruified using various methods
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Viruses are entities which are made of a few genes and are reliant on obligate parasitism to propagate. Due to the obligate connection to their hosts, virus evolution is constrained to the type of host. Viruses however do transmit to evolutionary distinct hosts; in these cases, the phylogenetic relationship of the hosts usually are close. LÄS MER
3. Separation of Nanoporous Silica Particles
Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : In this study a sample of particles in a size region of 0.05-10 μm were run through a centrifugation process with the ambition to make it monodisperse. The product requirements were stated as follows, particles within the size range of 2 to 3.8 μm should be isolated and separated from the sample with a D90/D10 < 1. LÄS MER
4. PREPARATION AND CHARACTERIZATION OF BOVINE MEAT AND MILK FACTOR VESICLES/PARTICLES & IDENTIFICATION OF MSBI1 REP INTERACTING PROTEINS
Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologiSammanfattning : Introduction: Bovine meat and milk factors (BMMF) frequently isolated from bovine meat and milk, are discussed as putative causative agents for breast, colon and possibly other cancers. The hypothesis was formulated based on earlier correlative studies indicating that BMMFs could indirectly trigger inflammation, accumulate mutational events via reactive oxygen and nitrogen species production which eventually provokes tumor formation.

5. Development and evaluation of a pre-analytical device for liquid biopsy
Uppsats för yrkesexamina på avancerad nivå,Sammanfattning : In this project, a novel method to discover and monitor cancer was studied. Tumoureducated platelets (TEPs) have shown the ability to take up tumour-derived secretedmembrane vesicles, which contain tumour RNA. Therefore they are of great interestfor detecting cancer and could potentially work as biomarkers. LÄS MER
