1. 16. Repair of DNA double-stranded breaks in human cells

   Författare :Susanne Nyström; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA-PK; DNA double-stranded break; DSB; DNA single-stranded break; SSB; DNA damage; ionizing radiation; IR; DNA repair; calicheamicin gamma1; bleomycin; etoposide; topoisomerase II; radiotherapy; radiosensitizer; ATM;

   Sammanfattning : DNA is continuously subjected to degradation. Therefore, our cells need to constantly repair its DNA to prevent mutations and in the long run cancer. In mammalian cells, when DNA is broken right off, a double-stranded break (DSB) is produced, and the ends are ligated by a process called non-homologous end-joining (NHEJ). LÄS MER

3. 17. Molecular studies in breast cancer susceptibility genes

   Författare :Jindong Chen; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :familial breast cancer; breast cancer susceptibility gene; BRCA1; BRCA2; ATM; TP53; PTEN MMAC1; STK11 LKB1; gene mutation; mutation screening; LOH;

   Sammanfattning : Breast cancer is the most common malignancy among women, with a cumulative risk of approximately 12% by the age of 85. Of the breast cancer cases, 5-10% are hereditary. LÄS MER

4. 18. Functional analysis of genetic variants in putative low penetrate breast cancer genes

   Författare :Haixin Lei; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Breast cancer; low penetrance gene; CDH1; ILC; IDC; mutation; SNP; BA CHI; ATM; EST1; cryptic splice site; SR proteins; dinucleotide repeats; splicing silencer.;

   Sammanfattning : Paper I & II: CDH1 germline mutations predispose individuals to diffuse gastric cancer, but its role in breast cancer is less clear. Somatic CDH1 mutations were reported to be frequent in lobular tumours (ILC), but they have not been found in ductal carcinomas (IDC). LÄS MER

5. 19. A genetic study on familial breast cancer predisposing genes

   Författare :Liping Luo; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Breast cancer is the most common malignant disease among women in the western world and 10% of all breast cancer is assumed to constitute hereditary cases. Two major genes, BRCA1 and BRCA2, can only explain a fraction of familial breast cancer. The ATM carriers have high risk of developing breast cancer. LÄS MER

7. 20. Low Power Techniques for Fast CMOS Buffer Memories

   Författare :Jonas Alowersson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems engineering; low-power; throughput; buffer memory; CMOS; SRAM; computer technology; Data- och systemvetenskap;

   Sammanfattning : The thesis deals with circuit-level aspects of CMOS buffer SRAMs where the data throughput rate is a more important metric than access time or storage capacity. One aspect is the increased write cycle related power consumption that is the consequence of a high write ratio combined with a long word-length. LÄS MER
