1. 6. Mesenchymal Stem Cells in Tumor Growth Inhibition and Cartilage Differentiation

   Författare :Laura Varas; Immunologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicinska vetenskaper; Medicine human and vertebrates ; Medicin människa och djur ; mesenchymal stem cell; Biomedical sciences; tumor growth inhibition; FGF2; cartilage; integrin alpha11beta1; integrin alpha10beta1;

   Sammanfattning : The work presented in this thesis has been focused on mesenchymal stem cells (MSCs). In the two first studies, the effects of MSCs on tumor growth and development in vitro and in vivo was investigated. LÄS MER

3. 7. Ascorbate in the ocular lens

   Författare :Vino C Jr Mody; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Purpose: First, we intended to establish a method for sample preparation for measurement of ascorbate in whole rat and guinea pig lenses utilizing ultrafiltration and high performance liquid chromatography with ultraviolet radiation detection. Then, we aimed to investigate whether, in the albino rat, lens ascorbate concentration depends on solid dietary intake. LÄS MER

4. 8. Functionally-associated target antigens in cancer. Defined by human antibodies and small interfering RNAs

   Författare :Johan Fransson; Institutionen för immunteknologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; phage display; Antibody; cancer; transplantation; Immunologi; serologi; serology; Immunology; onkologi; Cytologi; cancerology; oncology; Biochemistry; Metabolism; Biokemi; metabolism; Biotechnology; Bioteknik; Cytology;

   Sammanfattning : Cancer is the collective name for diseases that have one thing in common ? uncontrolled cell growth. The increase in cancer cell proliferation eventually results in tumor formation and, in the worst case, metastatic spread to other organs. Common treatment modalities of cancer include chemotherapy and radiation therapy. LÄS MER

5. 9. Infrared Neural Modulation: Photothermal Effects on Cortex Neurons Using Infrared Laser Heating

   Författare :Qingling Xia; Tobias Nyberg; Björn Granseth; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural modulation; infrared laser; in - vitro experiment; multi - electrode arrays MEA ; heating model; temperature; neural networks; infrared neural inhibition INI ; hyperexcitation;

   Sammanfattning : It would be of great value to have a precise and non-damaging neuromodulation technique in the field of basic neuroscience research and for clinical treatment of neurological diseases. Infrared neural modulation (INM) is a new modulation modality developed in the last decade, which uses pulsed or continues infrared (IR) light with a wavelength of 1200 to 2200 nm to directly alter neural signals.

7. 10. Influences of in vivo and in vitro loading on the proteoglycan synthesis of articular cartilage chondrocytes

   Författare :Mikko Lammi; Markku Tammi; Jukka Finne; Tim Hardingham; Finland Kuopio University of Kuopio Department of Anatomy; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Articular cartilage; proteoglycans; loading; stress; hydrostatic pressure; biokemi; Biochemistry; cell research; cellforskning; molekylärbiologi; Molecular Biology; ortopedi; Orthopaedics;

   Sammanfattning : In this study, the biosynthesis of proteoglycans (PGs) was examined in articular cartilage of canine hip joint after long-distance running experiment and in bovine chondrocyte cultures during in vitro loading with hydrostatic pressure. In addition, new assays were developed for more sensitive quantitation of glycosaminoglycans (GAGs) and PGs. LÄS MER
