  1. 1. Injectable Biomaterials for Spinal Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Alejandro López; Uppsala universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; injectable; biomaterials; bone cement; vertebral compression fractures; spine; radiopacity; minimally invasive treatment; low-modulus cement; oligomer; PMMA; calcium phosphate; vertebroplasty; bone; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : The use of injectable biomaterials is growing as the demands for minimally invasive procedures, and more easily applicable implants become higher, but their availability is still limited due to the difficulties associated to their design.Each year, more than 700,000 vertebral compression fractures (VCF’s) are reported in the US and 500,000 VCF’s in Europe due to primary osteoporosis only.

  2. 2. Osteocytes as indicators of bone quality - multiscale structure-composition characterisation of the bone-implant interface

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Furqan A. Shah; Göteborgs universitet.; Gothenburg University.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D printing; apatite; biomaterials; biomineralisation; bone; bone quality; canaliculi; CoCr; collagen; electron beam melting; electron microscopy; implant; interface; in vivo; lacuna; micropetrosis; osseointegration; osteocyte; Raman spectroscopy; surface modification; Ti6Al4V; titanium; ultrastructure; whitlockite;

    Abstract : By virtue of certain design features, bone anchored metal implants can be made to elicit a strong initial osteogenic response, i.e., the amount of bone formed. READ MORE

  3. 3. Biomaterials and Hemocompatibility

    University dissertation from Kalmar, Växjö : Linnaeus University Press

    Author : Anna E. Engberg; Linnéuniversitetet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Complement; Coagulation; Whole blood; Biomaterials; Polymers and Hemocompatibility; MEDICINE Microbiology; immunology; infectious diseases Immunology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Immunologi; Biomedical Sciences; Biomedicinsk vetenskap;

    Abstract : Biomaterials are commonly used in the medical clinic today; however, artificial materials can activate the cascade systems in the blood (complement-, coagulation-, contact- and fibrinolytic systems) as well as the platelets to various degrees. When an artificial surface comes in contact with blood, plasma proteins will be adsorbed to the surface within seconds. READ MORE

  4. 4. Biomaterials as carriers for bone active molecules-An approach to create off-the-shelf bone substitutes

    University dissertation from Lund University, Faculty of Medicine

    Author : Deepak Raina; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterials; Bone tissue engineering; Bone morphogenic protein-2; Zoledronic acid ZA ; calcium sulphate; Hydroxyapatite; Gelatin;

    Abstract : Bone tissue is commonly transplanted during orthopedic surgeries, primarily for the management of bone defects caused by trauma or various orthopedic conditions including, but not limited to, infections and tumours. Bone grafts are a surgeon’s choice, but their associated drawbacks are paving the way for biomaterial based bone graft substitutes. READ MORE

  5. 5. Interactions between platelets and complement with implications for the regulation at surfaces

    University dissertation from Växjö, Kalmar : Linnaeus University Press

    Author : Per H. Nilsson; Linnéuniversitetet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; complement system activation; regulation ; platelets activation; regulation ; biomaterials; biocompatibility; chondroitin sulfate-A; apyrase; C1q; C3; factor H; C4BP; ADP; Biomedicinsk vetenskap; Biomedical Sciences;

    Abstract : Disturbances of host integrity have the potential to evoke activation of innate immunologic and hemostatic protection mechanisms in blood. Irrespective of whether the activating stimulus is typically immunogenic or thrombotic, it will generally affect both the complement system and platelets to a certain degree. READ MORE
