2. 1. Stromal collagens in colorectal cancer and in colorectal liver metastases : tumour biological implications and a source for novel tumour markers

   Author : Hanna Nyström; Malin Sund; Peter Naredi; Per Sandström; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; colorectal liver metastases; tumour marker; stroma; type IV collagen; metastatic growth pattern; kirurgi; Surgery;

   Abstract : Background: Colorectal cancer (CRC) remains one of the leading causes of cancer-related mortality. About 50 % of patients with CRC will develop subsequent liver metastases (CLM). The survival for untreated CLM is only a few months and liver resection provides the only chance for a lasting cure. READ MORE

4. 2. Suitability of industrial residues for preventing acid rock drainage generation from waste rock

   Author : Elsa Nyström; Lena Alakangas; Hanna Kaasalainen; Christian Maurice; Päivi M. Kauppila; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geochemistry; Tillämpad geokemi;

   Abstract : One of the main and most challenging environmental problems related to mining is the generation of acid rock drainage (ARD), a leachate characterized by low pH and elevated concentrations of sulfate, metals, and metalloids formed when sulfide-bearing minerals are subjected to oxygen and water. During the operation of a mine, waste rock is often deposited in heaps and usually left under ambient conditions, enabling sulfides to oxidize. READ MORE

5. 3. Licence to drive : the importance of reliability for the validity of the Swedish driving licence test

   Abstract : Background: The Swedish driving licence test is a criterion-referenced test resulting in a pass or fail. It currently consists of two parts - a theory test with 65 multiple-choice items and a practical driving test where at least 25 minutes are spent driving in traffic. READ MORE

6. 4. Type IV collagen in breast and colorectal cancer : a potential biomarker of metastatic disease

   Author : Moa Lindgren; Hanna Nyström; Ingrid Ljuslinder; Malin Sund; Kristian Pietras; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; colorectal liver metastases; breast cancer; breast cancer metastases; tumor marker; biomarker; stroma; type IV collagen;

   Abstract : Background: Metastatic colorectal cancer (mCRC) and metastatic breast cancer (mBC) are two leading causes of cancer-related mortality worldwide. Early detection of metastatic disease is critical, and sensitive, easily accessed and cost-effective biomarkers that can diagnose mBC and mCRC at an early stage would have high clinical value.
