    Sammanfattning : The mature vascular system is composed of a network of blood vessels organized into arteries, capillaries, and veins. The vessels are composed of endothelial cells surrounded by smooth muscle cells and embedded in a specialized basement membrane. LÄS MER

    Sammanfattning : Down syndrome (DS) is associated with psychomotor retardation, short stature and endocrine dysfunction. Statural growth is a well-known indicator of health. The growth in DS differs markedly from that of other children and there is a 20 cm reduction of final height as compared to target height. LÄS MER

  4. 3. Head and Neck Cancer : Factors Affecting Tumour Growth

    Författare :Kaarina Sundelin; Elisabeth Paulette-Hultcrantz; Karin Öllinger; Karin Roberg; Hans Gustafsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Head and neck cancer; Chemoradiotherapy; Tumour; Malignant salivary; Metallothionein; Neo-angiogenesis; Metastases; Cytokine tumour necrosis factor-alpha; hepatocyte growth factor; Oncology; Onkologi;

    Sammanfattning : Head and neck cancer is the fifth most common cancer worldwide with an estimated annual global incidence of over 500 000 cases. These malignant tumours develop in the mucosal linings of the upper respiratory tract or in the salivary glands. The most common sites are in the oral cavity and larynx. LÄS MER

  5. 4. Growth factors in spermatogenesis

    Författare :Aida Wahlgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Testis; seminiferous tubules; proliferation; growth factors; sex steroids;

    Sammanfattning : The aim of this study was to increase the knowledge of die effects of locally produced growth factors and hormones on germ cell proliferation in rat testis in vitro. Since impaired sperm production and function accounts for half the cases of infertility, it is important to understand the physiological actions in germ cell development. LÄS MER

  7. 5. Early growth, retinopathy of prematurity and insulin-like growth factors in preterm infants

    Författare :Eva Engström; Göteborgs universitet; []
    Nyckelord :Preterm; ROP; nutrition; growth; growth restriction; IGF-I; IGF-II; IGFBP-3;

    Sammanfattning : Aims:Paper I: To perform measurements of the lower leg length (LLL) in preterm infants, compare and evaluate handling error and precision of two instruments, and estimate the time required to show growth.Paper II-IV: To investigate whether low postnatal levels of serum IGF-I are associated with abnormal retinal vessel development.
