11. Characterization and Use of a Multiplex PCR-based System: Random amplified Polymorphic DNA
Abstract : Random amplified polymorhic DNA (RAPD) is a PCR-based marker system that makes use of universal sets of short oligonucleotides that amplify random DNA fragments under low-stringency conditions. The RAPD marker system has found widespread use and possesses a number of very positive features, being a multiplex and universal system. READ MORE

12. Morphological Features and Mismatch Repair in Colorectal Tumors
Abstract : Corlorectal cancer affects 5% of individuals in the Western world and heredity is estimated to cause at least 10% of the tumors. Defective mismatch repair (MMR) is a tumorigenic mechanism through which about 15% of colorectal cancer develops and this feature characterizes tumors associated with Hereditary Nonpolyposis Colorectal Cancer (HNPCC) or Lynch syndrome.

13. Transcriptional regulation and effects on differentiation by LMO proteins and the basic helix-loop-helix factors TAL1 and HEN1
Abstract : Acute lymphoblastic leukemia (ALL) is the most widespread type of cancer, as well as the most frequent leukemia in children. Malignant ALL cells originate from normal T lymphocytes or B cells that are blocked at immature stages of differentiation. READ MORE

14. Organization of centromere associated DNA in Chironomus pallidivittatus
Abstract : Centromeres have not yet been functionally defined in higher eu- karyotes, largely due to the huge amounts of repeated DNA in these regions of most species and difficulties of delimiting centromeric from pericentric regions. Also the latter have large quantities of mostly noncoding DNA, expressed cytologically as pericentric heterochromatin. READ MORE

15. Avian Malaria and Related Blood Parasites: Molecular Diversity, Ecology and Evolution
Abstract : Malaria-like parasites consist of a large group of species that infects primates, rodents, bats, lizard and birds. I have focused on parasites from the genera Haemoproteus, Plasmodium and Leucocytozoon that are infecting birds. READ MORE
