  2. 1. Biodegradable magnesium implants, immunomodulation, and tissue repair/regeneration

    Author : Heithem Ben Amara; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adipose tissue; Biodegradable implants; Bone–implant interface; Bone marrow; Inflammation; Cellular mechanotransduction; Gene expression; Immunohistochemistry; Magnesium; Neovascularization; Osseointegration; Soft tissue injuries;

    Abstract : The century-old paradigm of holding fractures with a metallic implant to enable bone repair, known as osteosynthesis, is still used today without alteration. Patients are increasingly being treated with metallic implants made of magnesium (Mg) that secure osteosynthesis and are reabsorbed in situ without the surgical re-entry that requires their permanent analogs.

  4. 2. Synthesis, Characterisation and Properties of Biomimetic Biodegradable Polymers

    Author : Fredrik Nederberg; Tim Bowden; Nicola Tirelli; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; biodegradable polymers; biomimetic; phospholipid-like; phosphorylcholine; amphiphilic; ionomer; hemocompatible; non-adhesive; water uptake; reduced protein adsorption; protein delivery; Kemi; Chemistry; Kemi;

    Abstract : The acceptance of blood contacting implants creating favorable conditions in vivo is decisively determined by their interaction with proteins that mediate inter cellular interactions with synthetic substrates. Adsorbed proteins can activate blood cascade systems like coagulation and complement that may result in serious blood clots, and/or immunological reactions. READ MORE

  5. 3. X-ray and neutron μCT of biomedical samples: from image acquisition to quantification

    Author : Niccoló Peruzzi; Lund Medicinsk strålningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; x-ray imaging; neutron imaging; μCT; synchrotron radiation; x-ray phase-contrast; nanoholotomography; x-ray elemental mapping; biomedical applications; virtual histology; biodegradable implants; Mg-alloys; enteric nervous system; peripheral neuropathy; gastroenteric dysmotility; Fysicumarkivet A:2021:Peruzzi;

    Abstract : Even though the validity of x-ray computed tomography in the analysis of biomedical samples is nowadays undisputed, the more recent imaging techniques and more advanced instruments (such as synchrotrons) are still relatively unknown to many medical doctors that could benefit from them.The doctoral work presented in this thesis joins a collective effort from the imaging community to demonstrate potential applications of advanced x-ray and neutron imaging methods to preclinical medical research, with the hope of contributing to reach a “critical mass” in the medical community and in the public opinion as well.

  6. 4. Investigation of corrosion properties of metals for degradable implant applications

    Author : Karin Beaussant Törne; Jonas Weissenrieder; Wolf-Dieter Mueller; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biodegradable; metal; zinc; magnesium; corrosion; electrochemistry; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Nedbrytbara metaller utgör en ny klass av biomaterial med potential attersätta permanenta material i tillfälliga applikationer. Detta för att minskarisken för långvariga biverkningar. READ MORE

  7. 5. On magnesium-containing implants for bone applications

    Author : Silvia Galli; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The biomedical technologies for bone application are employed in millions of patients every year to restore function and aesthetics following trauma, diseases and congenital deformities. They achieved significant advancements in the last decades and have resulted in the development of implants that function for long periods of time. READ MORE
