1. 1. Novel Solid Phase Extraction and Mass Spectrometry Approaches to Multicomponent Analyses in Complex Matrices

   Författare :Nahid Amini; Gunnar Thorsén; Tuulia Hyötyläinen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sample preparation; SPE; RAM; GCB µ-trap; GCB disk; High temperature LC; LC MS; ESI; APCI; Matrix effects; LIT-MS; SALDI; Sample screening; Oxidized GCB; Silicon nitride; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : Analysis of compounds present in complex matrices is always a challenge, which can be partly overcome by applying various sample preparation techniques prior to detection. Ideally, the extraction techniques should be as selective as possible, to minimize the concentration of interfering substances. LÄS MER

3. 2. Diffuse large B-cell lymphoma – studies on immunohistochemical and clinical prognostic factors

   Författare :Sverker Hasselblom; Göteborgs universitet; []
   Nyckelord :DLBCL; prognosis; sex; population-based; apoptosis; Ki-67; CTLs; TIA-1; FOXP3; bcl-2; GCB; p-AKT;

   Sammanfattning : DLBCL, the most common lymphoma entity, is a potentially curable but heterogeneous disease. Most studies concerning therapy and prognostic factors have been performed on selected patient materials. It is important to identify immunohistochemical biomarkers which could add prognostic information to clinical factors. LÄS MER

4. 3. Textile Related Chemicals: Analytical Approaches Towards the Assessment of Human and Environmental Exposures

   Författare :Francesco Iadaresta; Conny Östman; Carlo Crescenzi; Jan Holmbäck; Peter Haglund; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; graphitized carbon black- GCB; franz cell; diffusion cell; risk assessment; screening; textile; Analytical Chemistry; analytisk kemi;

   Sammanfattning : The textile manufacturing chain involves an extensive use of chemicals as early as fabric-production. To confer special features to textile materials, more chemicals are required in subsequent steps. Furthermore, potentially harmful substances can end up in clothes as transformation products.

5. 4. Prognostic signficance of tumor cell markers in diffuse large B-cell lymphoma with special emphasis on lymphoma localization

   Författare :Maysaa Abdulla; Rose-Marie Amini; Gunilla Enblad; Wolfram Klapper; Uppsala universitet; []
   Nyckelord :;

   Sammanfattning : Diffuse large B-cell lymphoma (DLBCL) is the most common type of high-grade B-cell lymphoma with different clinical, morphological, immunophenotypical, and molecular features. DLBCL is curable in 60-70% of patients when treated with standard immunochemotherapy R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone). LÄS MER

7. 5. Novel clean-up, concentration and laser desorption/ionization strategies for mass spectrometry

   Författare :Mohammadreza Shariatgorji; Leopold Ilag; Juan Astorga-wells; Bernhard Spengler; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; ESI-MS; SALDI-MS; Electrocapture; Sample treatment; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : Despite valuable advantages of mass spectrometry (MS) techniques they still have drawbacks that need to be overcome, notably their sensitivity to various kinds of interfering substances and associated difficulties involved in detecting signals from analytes present in trace quantities. Thus, high quality analytical data could be acquired by improving sample pre-treatment techniques and/or ionization methods to increase ionization yields and/or avoid the generation of unwanted ions.
