    Sammanfattning : The aim was to evaluate first trimester nuchal translucency (NT) measurement for detection and risk assessment of fetal malformations and fetal loss. 39 572 pregnant women were randomised to either a routine ultrasound scan at 12-14 weeks including NT measurement or to a routine scan at 18-20 weeks.

    Sammanfattning : The present study was conducted in order to assess a role of the SH2 domain-containing adapter protein SHB in development and cell differentiation.Embryonic stem (ES) cells overexpressing SHB and SHB with an inactive SH2 domain (R522K-SHB) were obtained. LÄS MER

  3. 3. Developmental disturbances of the embryo in diabetic pregnancy

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Parri Wentzel; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; diabetes; pregnancy; embryo; malformation; glucose; ROS; SOD; NAC; prosta- glandin; COX; COX inhibitor; gene expression; Cellbiologi; MEDICINE Morphology; cell biology; pathology Cell biology; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Maternal diabetes during pregnancy constitutes an increased risk for congenital malformation in the offspring. Previous studies have suggested that diabetic embryopathy is associated with an excess of reactive oxygen species (ROS) as well as with a disturbance of prostaglandin (PG) metabolism. LÄS MER

  4. 4. Maternal smoking and congenital malformations

    Detta är en avhandling från Tornblad Institute, Biskopsgatan 7, S-223 65 Lund, Sweden

    Sammanfattning : About two percent of Swedish newborn infants are born with a significant congenital malformations which is reported to the Swedish Registry of Congenital Malformations (RCM), and/or the Swedish Medical Birth Registry (MBR). In spite of persistent public health recommendations, about 16% of the Swedish pregnant women are smoking during pregnancy (1996). LÄS MER

  5. 5. Cellular and molecular roles for CDC42 in angiogenesis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Marco Castro; Christer Betsholtz; Bàrbara Laviña; Rui Benedito; [2018]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CDC42; angiogenesis; endothelial cell; vascular malformation; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Sammanfattning : Angiogenesis is the physiological process by which new blood vessels grow and critically depends on the interplay between the major vascular units: endothelial cells, pericytes and smooth muscle cells. Dysfunction and mispatterning of blood vessels are associated with the progression of many vascular complications, and therefore, understanding the causes of vascular dysmorphia is a central question in vascular biology.
