2. 1. Telomerase in hematological and other malignancies : therapeutic implications

   Author : Bingnan Li; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The Telomere is a nucleoprotein complex consisting of TTAGGG repeated sequences covered by specialized binding proteins termed shelterins masking the end of linear chromosomes and thereby protecting the end of the chromosome from genomic instability. Telomeres become progressively shortened during cellular replication and acts as a mitotic clock to confer a limited lifespan to normal cells. READ MORE

4. 2. Radiation therapy of upper gastrointestinal cancers with scanned proton beams : A treatment planning study

   Author : Gracinda Mondlane; Albert Siegbahn; Michael Gubanski; Iuliana Toma-Dasu; Crister Ceberg; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Treatment planning; gastric cancer; liver metastases; photon beam therapy; proton beam therapy; dosimetric comparison; normal tissue complication probability; risk of radiation-induced secondary cancer; patient selection; Medical Radiation Physics; medicinsk strålningsfysik;

   Abstract : Proton beam therapy (PBT), using scanned beams, is an emerging modality used for the treatment of cancer. The clinical advantages of PBT, compared to commonly used photon beam therapy, have been demonstrated in different studies. READ MORE

5. 3. Comparative study of Radiation Therapy of Targets in the Upper Abdomen with Photon- or Scanned Proton-beams

   Author : Gracinda Mondlane; Albert Siegbahn; Michael Gubanski; Iuliana Toma-Dasu; Crister Ceberg; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; photon radiotherapy; proton beam radiotherapy; gastric cancer; liver metastases; Medical Radiation Physics; medicinsk strålningsfysik;

   Abstract : Recently, there has been an increase in the number of proton beam therapy (PBT) centers operating worldwide. For certain cases, proton beams have been shown to provide dosimetric and radiobiological advantages when used for cancer treatment, compared to the regular photon-beam based treatments. READ MORE

6. 4. Analysis of viral and cellular gene expression patterns in cells latently infected with EBV by suppression subtractive hybridization

   Author : Csaba Kiss; Karolinska Institutet; Karolinska Institutet; []
   Keywords : EBV; Suppression subtractive hybridization; high-throughput; DOP-PCR; TCL- 1; BLNK Burkitt s lymphoma; gastric cancer;

   Abstract : Epstein-Barr virus is a ubiquitous γ-herpes virus and causes the self-limiting lymphoproliferative disease, called infectious mononucleosis. Its presence is associated with several malignancies, including Burkitt lymphoma, gastric cancer and other malignant diseases. READ MORE

7. 5. Etiological aspects of gastroesophageal cancers : an epidemiological approach

   Author : Shahram Bahmanyar; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Nutrition; dietary patterns; factor analysis; esophageal cancer; stomach cancer; gastric; cardia; non-cardia; adenocarcinoma; squamous-cell carcinoma; duodenal ulcer; gastric ulcer; estrogen; parity; risk; case-control study; cohort study; nested case-control study; odds ratio; standardized incidence ratio;

   Abstract : Aims: The aims of this thesis were to study the association of overall dietary habits, duodenal ulcer and gastric ulcer diseases, as two models of Helicobacter pylori (H. pylori) infection and the development of gastroesophageal cancers to further explore the etiology of these malignancies.
