2. 6. Molecular mechanism of plasmid copy number control in Yersinia

   Author : Tifaine Héchard; Helen Wang; Javier Pizarro-Cerda; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia pseudotuberculosis; plasmid copy number; T3SS; infection; ddPCR; Mikrobiologi; Microbiology;

   Abstract : The ability of pathogenic bacteria to cause disease depends on various virulence mechanisms. The three pathogenic species of Yersinia use a type III secretion system (T3SS) to translocate effector proteins into host cells and disrupt the immune system. This T3SS is encoded on a 70kb, low-copy, virulence plasmid. READ MORE

4. 7. Percutaneous Nephrostomies : Planning for an Optimal Access, Complications, Follow-up and Outcome

   Author : Eva Radecka; Anders Magnusson; Marianne Brehmer; Torbjörn Andersson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Percutaneous nephrostomy; Percutaneious nephrolithotripsy; Complications; Puncture technique; CT guidance; Radiologisk forskning; Radiological research; Radiologisk forskning;

   Abstract : Percutaneous nephrostomy (PCN) is a well-established intervention performed to divert urine from the collecting system in ureteric obstruction or as a prelude to interventional procedures such as stent placement or percutaneous nephrolithotripsy (PCNL). The aim of this thesis is to enhance planning for an optimal insertion of PCN, investigate complications, long-term management, follow-up and outcome in patients with PCN treatment and to increase accuracy in CT-guided punctures.

5. 8. Studies on organochlorine environmental contaminants with emphasis on analytical methods and occurrence in humans

   Author : Cecilia Weistrand; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Methods for multicomponent analysis of lipophilic organochlorine contaminants(OCs) in blood plasma and lipid-rich tissues are presented. By using the described methods, polychlorinated biphenyls (PCB), polychlorinated naphthalenes (PCN), hexachlorobenzene(HCB), 1,1-dichloro-2,2-bis(4 chlorophenyl)ethene (p,p'-DDE) and methylsulphonyl metabolites of PCB (MeSO2-PCB) and p,p'-DDE (Meso2-DDE) were determined in human blood plasma, adipose tissue and liver.

6. 9. Properties and analysis of dioxin-like compounds in marine samples from Sweden

   Author : Kjell Lundgren; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; planar dioxin-like compound; polychlorinated dibenzofuran; polychlorinated biphenyl; polychlorinated naphthalene; alkylated polychlorinated dibenzofuran; high-performance liquid chromatography; PX-21 carbon column; biomagnification factor; biota to sediment accumulation factor; fluxes; relative retention time; mass spectrometry; relative response factor; ultra-violet spectroscopy; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

   Abstract : Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (PCBs) have been assigned toxic equivalency factors (TEFs). These compounds are today routinely analysed with sophisticated analytical techniques. READ MORE

7. 10. 2-acetylaminofluorene : metabolism and effects on drug-metabolizing enzymes

   Author : Anders Åström; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : 2-Acetylaminofluorene has been found to have two different kinds of effects on drug-metabolizing enzymes in rat liver :1. Short-term treatment with this compound induces the level of microsomal epoxide hydrolase and cytochromes P-450b+e, c, d and PB/PCN-E, with a concominant increase in the metabolism of 2-acetylaminoflurene itself.
