BIOCOMPATIBILITY OF PLASTICS
The International Organization for Standardization (ISO) presents widely adopted medical device guidelines that are aimed with a keen focus towards risk management. Biocompatibility testing for these devices and device components is addressed by ISO standard 10993. RESINATE 2017 Well-defined material characterization is a fundamental requirement in biocompatibility assessment. This...
Biocompatible mini energy storage device for direct diagnosis in the body
Miniatur-Sensoren, die Vitalwerte direkt im Körper bestimmen sollen, sind hochkomplexe Systeme. Eine der größten Hürden stellt die Energieversorgung dar. An der TU Chemnitz haben Wissenschaftler jetzt Energiespeicher entwickelt, die zwar nur so groß wie ein Staubkorn sind, aber Spannungen vergleichbar mit einer AAA-Batterie liefern. Biosuperkondensatoren (BSCs)“. Sie besitzen zwei herausragende...
bioprinting tissue-like constructs capable of controlled, complex shape change
Where standard 3D printing uses a digital blueprint to manufacture an object out of materials like plastic or resin, 3D bioprinting manufactures biological parts and tissues out of living cells, or bioinks. A fourth dimension — shape transformation over time — can be achieved by incorporating materials that enable printed...

Converting blood type A donor lungs into universal blood type lungs
Ex vivo enzymatic treatment converts blood type A donor lungs into universal blood type lungs A major challenge in lung transplantation is the need for ABO blood group matching. To address this challenge, Wang et al. used two enzymes, FpGalNAc deacetylase and FpGalactosaminidase, to convert blood group A lungs to blood group...

Metal-Specific Biomaterial Accumulation in Human Peri-Implant Bone and Bone Marrow
Metallic implants are frequently used in medicine to support and replace degenerated tissues. Implant loosening due to particle exposure remains a major cause for revision arthroplasty. The exact role of metal debris in sterile peri-implant inflammation is controversial, as it remains unclear whether and how metals chemically alter and potentially...
Research network in Hanover conducts research on intelligent implants
Researchers from a wide range of disciplines will work together to develop intelligent implant systems for the dental, skeletal and hearing areas, which for the first time will allow continuous monitoring of implant function and thus early detection of complications such as infections. Intelligent implant systems are to be developed...

Satisfaction with Total Knee Prosthesis (german)
Satisfaction with Knee-TEP depends mostly from expectations, grade of functional improvement and pain course. Roland Fath Laut einem systematischen Literatur-Review mit Daten von 2005 bis 2016 hängt die Zufriedenheit von Patienten mit Knie-TEP in erster Linie von den Erwartungen vor dem Eingriff, vom Ausmaß der Funktionsverbesserung und dem Schmerzverlauf ab...
Scientific investigation of sterile packaged medical devices (german original)
100 originally packaged dental implants were examined for residues using a scanning electron microscope. The following materials were found: Metallic particles with significant amounts of copper, tin, chromium, iron, tungsten and nickel. Filmic residues and carbon containing particles. Chemicals such as erucamide, dodecylbenzene sulfonic acid. The author discusses the medical...
Spelling interface using intracortical signals enabled neurofeedback training
Spelling interface using intracortical signals in a completely locked-in patient enabled via auditory neurofeedback training Patients with amyotrophic lateral sclerosis (ALS) can lose all muscle-based routes of communication as motor neuron degeneration progresses, and ultimately, they may be left without any means of communication. Here, we implanted two 64 microelectrode...
Wait time for hip fracture surgery – association
Association Between Wait Time and 30-Day Mortality in Adults Undergoing Hip Fracture Surgery D Pincus et al. Among adults undergoing hip fracture surgery, increased wait time was associated with a greater risk of 30-day mortality and other complications. A wait time of 24 hours may represent a threshold defining higher...
Wissenschaftliche Untersuchung steril verpackter Medizinprodukte
100 original verpackte Zahnimplantate wurden mit einem Rasterelektronenmikroskop auf Rückstände untersucht. Folgende Materialien wurden gefunden: Metallische Partikel mit deutlichen Anteilen von Kupfer, Zinn, Chrom, Eisen, Wolfram und Nickel. Filmische Rückstände und kohlenstoffhaltige Partikel. Chemikalien wie z. B. Erucamid, Dodecylbenzolsulfonsäure. Der Autor diskutiert die medizinische Relevanz dieser Befunde. Author(s) Source Duddeck...
