    Sammanfattning : The C. elegans pharynx is a single cell thick muscular tube that undergoes morphogenesis to attain it mature structure from a ball of 80 undifferentiated cells. This thesis is about understanding the mechanisms and the genetic pathways underlying the process of pharyngeogenesis. LÄS MER

  3. 2. Farewell to peasantry? : (Post)modernising rural Mexico - The case of the ejido peasants in the Isthmus of Tehuantepec

    Författare :Sandra Fernández C; Institutionen för kulturgeografi och ekonomisk geografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mexico; qualitative methods; campesinos; ejido system; geographies of exclusion and resistance; Rural development; depeasantisation process; Isthmus of Tehuantepec; Social geography; Socialgeografi;

    Sammanfattning : The thesis deals with a classical issue, that of the fate of the peasantry, in particular the process of the transformation of the peasantry. The aim is to explore whether there is a place for the smallholding peasantry in the future, or if the process of dissolution is inevitable. LÄS MER

  4. 3. Epidermal stem cells in physiological tissue regeneration, wound healing and cancer

    Författare :Anja Füllgrabe; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The mammalian skin is a versatile organ that protects from external harm, regulates the body temperature, and provides the touch sensation. Its epithelium, the epidermis, forms several highly regenerative structures as the hair follicle (HF), the sebaceous gland (SG), and the interfollicular epidermis (IFE). LÄS MER

  5. 4. Ultrasound measurement of cervical length in the second trimester of pregnancy for prediction of preterm delivery

    Författare :Pihla Kuusela; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preterm delivery; transvaginal ultrasound; cervical length measurement; second trimester; prospective study; observational study; mass screening; reproducibility of results; inter-observer variation; intra-observer variation; data accuracy; quality control;

    Sammanfattning : Abstract Background: Short cervical length is a risk factor for preterm delivery (PTD) and screening of cervical length using transvaginal ultrasound in the second trimester is a proposed method to find women at risk Aims: To examine the potential value of routine measurement of cervical length in a Swedish population of women with singleton pregnancies in the prediction of PTD. To estimate inter- and intra-observer agreement and reliability of cervical length measurements. LÄS MER

  7. 5. Cryoablation of cardiac arrhythmias

    Författare :Hamid Bastani; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis evaluates the safety and efficacy of cryoablation in supraventricular tachyarrhythmias. In Study I, the acute and long-term outcome of cryoablation therapy of typical atrioventricular nodal reentrant tachycardia (AVNRT) was studied in a large series of patients (n=312). LÄS MER
