2. 1. Unique Solutions to Universal Problems : Studies of the Archaeal Cell

   Author : Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Archaea; Cdv; Cell cycle; Cell division; Cell lysis; Crenarchaea; ESCRT-III; Flow cytometry; Microarray; Microscopy; Nitrosopumilus; SIRV2; Sulfolobus; Thaumarchaea; Transcription; VAP; Virus; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

   Abstract : Archaea is one of the three domains of life and studies of archaeal biology are important for understanding of life in extreme environments, fundamental biogeochemical processes, the origin of life, the eukaryotic cell and their own, unique biology. This thesis presents four studies of the archaeal cell, using the extremophilic Sulfolobus and ocean living Nitrosopumilus as model systems. READ MORE

4. 2. The eukaryotic ribosome in focus : a chemical footprinting analysis of ribosome-ligand interactions in in vivo assembled complexes

   Author : Marika Salonen Sloma; Diarmaid Hughes; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi; Zoological Cell Biology; zoologisk cellbiologi;

   Abstract : Protein synthesis is an essential biological process that occurs on ribosomes. The process requires an involvement of numerous components like mRNA, tRNA and translation factors. The mammalian 80S ribosome, the focus of this thesis, is composed of four rRNAs and approximately 80 proteins distributed in two subunits the 40S and 60S subunit. READ MORE

5. 3. Aseptic Loosening of Orthopedic Implants : Osteoclastogenesis Regulation and Potential Therapeutics

   Author : Mehdi Amirhosseini; Anna Fahlgren; Göran Andersson; Teun J. de Vries; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Aseptic loosening is the main cause of failure of orthopedic prostheses. With no pharmaceuticals to prevent or mitigate periprosthetic bone degradation, a surgery to replace the loose implant with a new one is the only choice to restore patients’ function. READ MORE

6. 4. Microfluidic Cell and Particle Sorting using Deterministic Lateral Displacement

   Author : Stefan Holm; Fasta tillståndets fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; Separation science; Deterministic Lateral Displacement; Cell analysis; Deterministic lateral displacement; Microfluidics; Particle sorting; Droplet microfluidics; trypanosomiasis; red blood cell; Cell sorting; Fysicumarkivet A:2018:Holm;

   Abstract : Microfluidics is a field which has the potential to revolutionize medical diagnostics. The ability to sort and analyse cells by the use of portable handheld devices has the potential to enable sensitive devices for point-of-care diagnostics. READ MORE

7. 5. Cell and Particle Trapping in Microfluidic Systems Using Ultrasonic Standing Waves

   Author : Mikael Evander; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustic particle manipulation; standing waves; trapping; ultrasound; cell handling; particle handling; Microsystem technology; lab on a chip; microfluidics;

   Abstract : Analysis methods are currently being miniaturized in order to save time and money while achieving higher sensitivities. The ultimate goal is to create a lab-on-a-chip where all analysis steps and instruments can be automated and integrated into a single chip. READ MORE
