2. 1. Intestinal mucins 'soluble and insoluble problems'

   Author : Annkatrin Herrmann; Institutionen för experimentell medicinsk vetenskap; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal carcinoma; pulse labelling; organ culture; glycopeptide; small intestine; colon; glycoprotein complex; insoluble; muc2; MUC2; Mucin; mucus; carbohydrate; oligosaccharide.; Gastro-enterology; Gastroenterologi;

   Abstract : Highly glycosylated glycoproteins – mucins – are the major constituents of the mucus layer and glycocalyx that cover mucosal surfaces. Twelve human mucin genes have been identified, and the mucins may be divided into those that are membraneassociated and those that are secreted. READ MORE

4. 2. Mechanisms of below-ground carbon cycling in subarctic ecosystems

   Author : Maria Olsrud; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; pedology; geomorphology; Physical geography; subarctic tundra; phosphorous mobilization; organic acids; open top chamber experiment; 15N natural abundance; Ericoid mycorrhizas; global change; 14C pulse-labelling; Carbon allocation;

   Abstract : Some components of the below-ground carbon (C) cycle in terrestrial ecosystems are still poorly understood. A better understanding will be necessary to predict adequately the impacts of global change factors on C cycling and storage, especially in high-latitude ecosystems, where much of the C is stored below-ground.

5. 3. Improvements of the Bromodeoxyuridine-DNA Flow Cytometry Method for the Study of Cell Proliferation

   Author : Maria C Johansson; Bröstcancer-genetik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; head and neck cancer; [3H]thymidine; energy transfer; cell cycle; xenografted tumours; cultured cells; potential doubling time; labelling index; DNA synthesis time; cell proliferation; growth kinetics; Bromodeoxyuridine; DNA flow cytometry; cancer; onkologi; Cytologi; cancerology; oncology; Cytology;

   Abstract : Potential doubling time (Tpot), DNA synthesis time (TS), and labelling index (LI) are fundamental growth kinetics parameters in clinical and experimental cancer research, which may be of further practical importance regarding prognosis and treatment prediction of cancer. They can be measured by bromodeoxyuridine(BrdUrd)/flow cytometry (FCM) methods, where BrdUrd, an analogue of thymidine, is incorporated into DNA and quantified simultaneously with the DNA content.

6. 4. Capacitive Biosensor - A Tool for Ultrasensitive Analysis : Application in Clinical Analysis and Process Monitoring

   Author : Kosin Teeparuksapun; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capacitive Biosensor; Ultrasensitive Analysis; Clinical Analysis; Bioprocess Monitoring; Human Serum Albumin; HIV-1 p24; Host Cell Proteins; Protein A; Current Pulse;

   Abstract : Increasing demands for highly sensitive, accurate, fast and portable analytical assays have led to the development of new analytical tools. The integration of highly specific biological sensing elements and appropriate transducers has enabled design of even more efficient biosensor devices for the detection of target substances.

7. 5. On the labeling of Signal Constellations

   Author : Johan Lassing; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The work in this thesis studies a simple model of a digital communication system in which the transmitter operates on a sequence of information bits by grouping them into blocks of m bits and mapping such blocks onto one out of M = 2m waveforms, which is transmitted over the channel. The receiver recovers the original message by demapping the transmitted signals disturbed by noise back to m-bit blocks using maximum-likelihood symbol detection. READ MORE
