  1. 1. Thyroid cancer studies on etiology and prognosis

    University dissertation from Umeå : Umeå universitet

    Author : Arne Hallquist; Umeå universitet.; [1994]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thyroid cancer; prognostic factors; etiology; occupation; medical ionizing radiation; reproductive; and family factors;

    Abstract : Thyroid cancer constitutes about 1% of all malignant tumours and the incidence is increasing in Sweden. It is rare in children before the age of 10. During puberty the female to male ratio increases to be two to three times more common in females. The ratio remains constant until menopause and thereafter declines. READ MORE

    Abstract : 131I is widely used clinically in the treatment of Graves´ disease and differentiated thyroid cancer. However, cellular and molecular effects of 131I irradiation in relation to absorbed dose are poorly documented. READ MORE

  3. 3. Molecular regulation of thyroid development. New mechanisms of normal and defective morphogenesis

    University dissertation from Umeå : Umeå universitet

    Author : Henrik Fagman; Göteborgs universitet.; Gothenburg University.; [2004]

    Abstract : Congenital hypothyroidism (CH) is untreated a major cause of mental retardation. The majority of cases are due to malformations of the gland (dysgenesis). Little is known of molecular mechanisms regulating thyroid morphogenesis. READ MORE

  4. 4. Calcium Homeostasis After Thyroid Surgery

    University dissertation from Department of Surgery and Gastroenterology, Lund University Hospital, SE-221 85 Lund, Sweden

    Author : Pia Lindblom; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PTH-peripheral effects; hPTH- 1-34 infusion; EDTA infusion; Set-point; Vitamin D3; PTH; Calcium; Thyroid surgery; Postoperative hypocalcemia; Bone density.; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Reduced thyroid hormones;

    Abstract : Calcium homeostasis after thyroid surgery was studied during the immediate postoperative period and after one year. One day after hemithyroidectomy ionised calcium decreased whereas basal PTH did not change. EDTA stimulated maximal and total PTH secretion and set-point decreased on postoperative day 1 and normalised on day 7. READ MORE

  5. 5. Regulation of apoptosis in the thyroid epithelium

    University dissertation from Department of Surgery and Gastroenterology, Lund University Hospital, SE-221 85 Lund, Sweden

    Author : Abeba Demelash; Göteborgs universitet.; Gothenburg University.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thyroid; Apoptosis; Caspase; Calpain; Hydrogen peroxide; TGF-beta; Staurosporine; Selenium; Cytochrome c;

    Abstract : Apoptosis or programmed cell death allows the multicellular organism to remove cells that are in excess or potentially dangerous. Apoptosis has to be strictly controlled, yet inappropriately activated or suppressed apoptototic may contribute to a variety of diseases, including cancer, autoimmune disorders and neurodegenerative conditions.
