  2. 1. From dopamine nerve fiber formation to astrocytes

    Author : Franziska Marschinke; Ingrid Strömberg; Cecilia Lundberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dopamine; dopaminergic neurons; astroglia; Cell biology; Cellbiologi; Histology; Histologi; neurologi; Neurology;

    Abstract : Parkinson’s disease (PD) is a progressive neurodegenerative disease and characterized by the loss of dopaminergic (DA) neurons in the substantia nigra in the midbrain. The causes of the disease are still unknown. READ MORE

    Abstract : Cancer represents a significant global public health challenge and ranks as the second mostcommon cause of death in the United States. The onset of cancer entails an initial phasewhere cells lose their polarity and disconnect from the normal basement membrane, allowingthem to form distinct three-dimensional (3D) configurations that interact with adjacent cellsand the surrounding microenvironment.

    Abstract : Small intestine neuroendocrine tumors (SI-NETs) and lung carcinoids (LCs) are relatively indolent tumors, which originate from neuroendocrine (NE) cells of the diffuse NE system. Metastases can spread before diagnosis. Thus, potential cures become unavailable, which entitles new biomarker development. READ MORE

  6. 4. Basement membrane collagens in pancreatic cancer : novel stroma-derived tumor markers and regulators of cancer cell growth

    Author : Daniel Öhlund; Malin Sund; Peter Naredi; Matthias Löhr; Umeå universitet; []
    Keywords : Pancreatic cancer; tumor marker; basement membrane; type IV collagen; type XVIII collagen; matrix metalloproteinase; integrin; autocrine loop; tumor stroma; kirurgi; Surgery;

    Abstract : Background: Among the common malignancies, pancreatic cancer has the shortest long-term survival. The aggressive, rapid, and infiltrative growth pattern of pancreatic cancer, together with the lack of specific symptoms, often leads to late diagnosis. READ MORE

  7. 5. Isolation of Circulating Tumor Cells with Acoustophoresis : Towards a biomarker assay for prostate cancer

    Author : Eva Undvall; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Biomarkers; Cell separation; Circulating tumor cells CTCs ; Elastomeric particles; Microfluidics; Negative selection; Prostate Cancer;

    Abstract : Microfluidics has emerged as an essential approach in the development of novel technological platforms to detect and isolate rare circulating tumor cells (CTCs) in the blood of cancer patients. Micro-scaled fluidic systems offer means to precisely control fluid flow. READ MORE
