3. 2. Endometrial receptivity and human embryo implantation : in vivo and in vitro studies

   Författare :Sujata Lalit Kumar; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :3D-endometrial cell construct;

   Sammanfattning : Background: Infertility, one of the common gynaecological disorders, affects 10-15% women in their reproductive years. Despite the advances in assisted reproduction techniques and the best efforts of infertility specialists, implantation rates do not exceed more than 28-30%. LÄS MER

4. 3. Infrared spectroscopy : Method development and ligand binding studies

   Författare :Saroj Kumar; Andreas Barth; Janos Mink; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Infrared; Ligand binding; method development; Biophysical chemistry; Biofysikalisk kemi; biofysik; Biophysics;

   Sammanfattning : Infrared spectroscopy detects molecular vibrations and assesses the properties of molecules and their environment. It is a powerful technique to detect ligand induced changes in biomolecules as it has distinct signals and provides different levels of structural information. LÄS MER

5. 4. The application of microfluidic devices and multifunctional fibers in cancer diagnostics

   Författare :Tharagan Kumar; Aman Russom; Fredrik Laurell; Gustaf Mårtensson; Johan Kreuger; KTH; []
   Nyckelord :Circulating tumor cells; microfluidics; point of care; inertial microfluidics; elasto inertial microfluidics; nano-cellulose; layer-by-layer; optical fiber; microflow cytometer.; Bioteknologi; Biotechnology;

   Sammanfattning : Efficient separation and detection of rare cells in a mixed population is important in many biomedical applications. For instance, isolating and detecting circulating tumor cells (CTCs) from whole blood samples could allow for early cancer diagnosis and prognosis during treatment. LÄS MER

7. 5. Anthropometry in the elderly. Population studies on longitudinal changes, secular trends and risk for morbidity and mortality

   Författare :Debashish Kumar Dey; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anthropometry; height; body weight; body mass index; waist circumference; longitudinal changes; ageing; secular trends; stroke; morbidity; mortality; elderly;

   Sammanfattning : The aims of this thesis were to a) describe longitudinal changes in height and body weight (BW) between the ages 70 and 95y; b) describe secular trends in height and BW of 70-year-olds and their relation to social and lifestyle factors; c) investigate waist circumference (WC) and body mass index (BMI) at age 70 as risk for stroke during a 15-y follow-up; and, d) examine the relationship between 1) BMI at age 70 and 15-y all- cause mortality, 2) the percentage of weight change from age 70 to 75 and subsequent 5- and 10-y mortality. The studies were performed within the framework of the gerontological and geriatric population studies in Göteborg, Sweden-the H70 studies. LÄS MER
