  2. 1. The genomic basis of the response to female-limited X-chromosome evolution

    Author : Yesbol Manat; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X chromosome; Sex chromosome; Drosophila melanogaster; Experimental evolution; sexual selection; intralocus sexual conflict;

    Abstract : In this thesis, I attempted to achieve a better understanding of the nature of X-linked polymorphic loci using a female-limited X chromosome (FLX) experimental evolution in Drosophila melanogaster. I expected that expressing the evolved X chromosome will result in an increase in female fitness and a decrease in male fitness. READ MORE

  4. 2. Molecular mechanisms in cervical carcinogenesis : Studies of clonality, somatic genetic alterations and human papillomavirus variants in cervical pre-invasive and invasive cancer

    Author : Zhongmin Guo; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; cervical cancer; CIN; clonality; X-chromosome inactivation; LOH; HPV; chromosome 3p; chromosome 6; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Abstract : Cervical cancer derives from a series of pre-invasive cervical neoplastic lesions termed CIN I-III (Cervical Intraepithelial Neoplasia) via typical multiple-step processes. In contrast to premalignant disorders in other organs, different degrees of CIN possess a distinct biological behaviour where a proportion spontaneously regress or persist, whereas some progress to invasive cancer.

  5. 3. Image Analysis Techniques for Segmentation, Classification and Presentation of High-Resolution Prometaphase Chromosome

    Author : Stefan Nivall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aberration; segmentation; digital image analysis; high-resolution CCD camera; classification; prometaphase; chromosome; database;

    Abstract : The extraction, analysis, and presentation of integrated optical density (IOD) profiles from banded prometaphase chromosome material is an increasingly important clinical method for the detection and analysis of structural aberrations. Particular translocations, duplications, or deletions of genetic material have been shown to be implicated in specific mental or physical disorders. READ MORE

  6. 4. Evolutionary Studies of the Mammalian Y Chromosome

    Author : Linda Hellborg; Hans Ellegren; Terry Burke; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Y chromosome; field vole; cattle; selection; primer design; Genetik; Clinical genetics; Klinisk genetik;

    Abstract : Sex chromosomes are useful in elucidating the evolutionary factors affecting diversity and divergence. In particular, Y chromosome analyses may complement studies using mitochondrial DNA for inferring sex-specific population genetic processes. READ MORE

  7. 5. Turner syndrome. Relation between genotype and phenotype and long-term follow-up studies

    Author : Mohamed Mostafa El-Mansoury; Göteborgs universitet; []
    Keywords : Turner syndrome; chromosome; cardiovascular disease; body balance; fracture; hearing; hypothyroidism; liver;

    Abstract : Turner syndrome (TS) is a chromosomal disorder with a prevalence of approximately 1/2 500 live female births. There is complete or partial absence of one of the two sex chromosomes, resulting in a genetic constellation of 45,X monosomy or 45,X/46,XX mosaic, respectively. READ MORE
