  1. 1. Muscle function and physical activity in pre-pubertal school children

    Författare :Susanna Stenevi Lundgren; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; children; physical activity; exercise; isokinetic muscle strength; vertical jump height; normative; intervention; school transport; DXA; anthropometry; fat mass; lean mass; weight; height; body mass index; girls; boys; pre-pubertal;

    Sammanfattning : Background: Regular participation in physical activity or organized exercise is regarded as one important lifestyle factor that could improve musculoskeletal health, fitness and body composition. For children and adolescents physical activity is important not only in training of the neuromuscular system, coordination and balance, but in a wider perspective, for adopting a lifestyle that possibly reduces the risk of coronary artery disease, obesity, osteoporosis and other contributors to morbidity and mortality in the population.

  3. 2. Physical Activity, Bone Mass and Bone Structure in Pre-pubertal Children

    Författare :Gayani Alwis; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone size; BMD; BMC; hip structure analysis; DXA; boys; Physical activity; girls; acclerometers; school transportation;

    Sammanfattning : Low bone mineral density (BMD) is a risk factor for fractures and much of the fracture preventive effort today is devoted to preventing low BMD. Physical activity (PA) has been described as one of the best strategies to optimize skeletal development in the growing child. LÄS MER

  4. 3. Artificial testis to study early gonadal development and germ cell differentiation

    Författare :Ahmed Reda; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Studying the early germ cell development is of great significance, as germ cells transfer the genetic material between generations. However, in humans, this type of studies in vivo is not applicable, for obvious ethical reasons. LÄS MER

  5. 4. Reproductive biotechnologies in Swedish male alpacas

    Författare :Maria Celina Abraham; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Alpacas have become more popular during the last decades. The herds have been built up by importing live animals since reproductive biotechnologies, for example artificial insemination and semen preservation, are not well-developed in this species. LÄS MER

  7. 5. Childhood Obesity and Islet Function

    Författare :Johan Staaf; Peter Bergsten; Anders Forslund; Hindrik Mulder; Uppsala universitet; []

    Sammanfattning : The prevalence of childhood obesity and Type 2 Diabetes Mellitus (T2DM) has increased during recent decades. T2DM is accompanied with functional changes in the islets of Langerhans, which can be identified early in the pathogenesis. LÄS MER
