  1. 21. Gut microbiota in colorectal cancer : The importance of Parvimonas micra

    Author : Thyra Löwenmark; Richard Palmqvist; Sofia Edin; Pär Larsson; Michael Dahlberg; Per Hellström; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; mucosal microbiota; Parvimonas micra; Fusobacterium nucleatum; immunity; survival; biomedical laboratory science; biomedicinsk laboratorievetenskap;

    Abstract : Colorectal cancer (CRC) is a heterogenous disease consisting of multiple molecular subtypes, each of which has diverse treatment responses and prognoses. The importance of the gut microbiota in CRC development and progression has undergone increasing recognition in recent years, with a structural segregation in terms of microbial composition between CRC patients and healthy controls.

  2. 22. Superantigens in group A streptococcus : gene diversity and humoral immune response

    Author : Linda Maripuu; Mari Norgren; Susan Hollingshead; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Group A streptococcus; Streptococcus pyogenes; superantigen SAg ; SAg-gene profile; M-protein; emm-genotype; biomedicinsk laboratorievetenskap; biomedical laboratory science;

    Abstract : Group A streptococcus (GAS) is a strictly human pathogen that causes infections ranging from asymptomatic carriage to the highly lethal streptococcal toxic shock syndrome (STSS). GAS are classified according to the sequence of the variable 5’ end of the emm-gene that encodes the surface associated M-protein. READ MORE

  4. 24. Silicon neural interfaces -Design and biomedical aspects-

    Author : Lars Wallman; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; pn-etch stop; biocompatibility; neural recordings; porous silicon; silicon; neural interface; sieve electrode; General biomedical sciences; Biomedicinska vetenskaper allmänt ;

    Abstract : This thesis covers the development of a silicon neural interface, with focus on silicon sieve electrode fabrication, design, nerve regeneration, signal recording and biocompatibility. A study of how the via hole size and transparency of the perforated sieve membrane influences the nerve regeneration is presented together with a study on soft tissue responses to planar and porous silicon.

  5. 25. Polyester dendrimers for biomedical applications

    Author : Patrik Stenström; Michael Malkoch; Javier de la Mata; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Dendrimers are perfectly defined and highly branched large molecules with a high density of functional groups that makes them interesting for a variety of biomedical applications such as drug delivery, theranostics and as antimicrobials. Their synthesis can be complicated, time-consuming and expensive which has been an obstacle to their success. READ MORE
