Hydrothermal synthesis of coccolith rich chalk to hydroxyapatite
Calcium carbonates originating from marine sources show unique pore structure and nano–architecture, offering potential in the field of hard tissue engineering. It is hypothesised that the use of naturally–sourced raw materials for the synthesis of hydroxyapatite (HA), as a component of a hard tissue constructs, enables enhanced bone remodelling due to the biomimetic physical–chemical ...

Enhancing low cost stainless steel implants: bioactive silica–based sol–gel coatings with wollastonite particles
A hybrid organic–inorganic sol–gel coating with the addition of wollastonite particles is used as a potential solution to improve performance of low cost AISI 316L stainless steel. This work is focused on characterising the coatings by studying their synthesis and deposition, electrochemical, and in vitro and in vivo response. The coated implants presented in vitro Ca/P–rich ...

Polysaccharides Function as Backbone for Embryonic Osteogenesis
Osteogenesis, or new bone formation, begins in the early stages of embryonic development and continues postnatally until skeletal maturity is reached in early adulthood. Osteogenesis reoccurs in the event of bone trauma, such as a fracture or surgically created defect. Bone mass can also increase in response to chronic weight bearing from daily use or decrease due to a lack of movement or applied ...

Neutral atom beam technique enhances bioactivity of PEEK
Abstract Polyetheretherketone (PEEK) is currently gaining popularity in orthopedic and spinal applications but has potential drawbacks in use. PEEK is biocompatible, similar in elasticity to bone, and radiolucent; however, it has been shown to be inert and does not integrate well with bone. Recent efforts have focused on increasing the bioactivity of PEEK by modifying the surface to improve the ...

The development of an anthropomorphic and anthropometric thorax female phantom for experimental radiodosimentry
Anthropomorphic-anthropometrical phantoms are simulator objects for measuring absorbed dose in conditions equivalent to those found in the exposure of the internal organs to charged particles, photons or neutrons generated by external beams or to internal intake of radioisotopes. This paper addresses the construction of an anatomical simulator that retains the anthropomorphic and anthropometrical ...

Oxygen therapy for rheumatology
HBOT is a very effective adjunctive treatment for Rheumatoid Arthritis procedures Rheumatoid arthritis is a chronic inflammatory autoimmune disorder that can affect the lining of the joints and cause painful swelling that will result in the erosion of bones and the deformation of joints, which aggravated, leads to physical disabilities. As an autoimmune disorder, rheumatoid arthritis ...

Synthesis of biphasic calcium phosphate powders by a simple hydrolysis process
An ideal bone grafting material should be compatible with physiological environment, provoke osseous tissue formation and adapt degradation behaviour to new bone tissue growth. Calcium phosphates, a main inorganic constituent of the human hard tissue, are by far the best substitute materials for bone reconstruction because of their excellent bioactivity, biocompatibility and osteoconductivity. In ...

Titanium but not just titanium
Titanium and its alloys have many advantages as surgical implant materials, such as low density, high strength, good toughness, good biocompatibility, non-toxicity, low elastic modulus, good corrosion resistance, and low X-ray absorption rate Etc., thus occupying an increasingly important position in medical metal materials. Titanium and its alloys can be used for the repair and replacement of ...

Editorial: Quantitative Susceptibility Mapping in Neurodegeneration
Introduction Magnetic resonance imaging offers a wide variety of contrast mechanisms to study soft tissue in the body. Using the complex data from the SWI scans, it is possible to produce magnetic source images using a novel reconstruction method that takes the phase data and reconstructs what is referred to as a quantitative susceptibility map (QSM). The phase images represent local frequency ...

Multifunctional Black Bioactive Ceramic Material Developed Recently
Bioceramic materials have a long history of being used to repair human hard tissues, from biologically inert materials (such as alumina and zirconia, etc.) to biological materials that are both biologically active and degradable (such as phosphate and silicate bioceramics, silicon Based bio-glass, etc.), its physiological function is no longer a simple tissue filling substitute, but a tissue ...

Exoskeleton instead of a wheelchair
At the moment, there’s a wide range of rehabilitation aids available for people with impaired mobility: diverse walkers, light and robust crutches, tons of various wheelchairs. All of them have certain flaws and weaknesses. For instance, state-of-the-art wheelchairs make it possible to go in for sports, travel at a rather high speed, and are user-friendly, but all of those aspects ...

Bridging Art & Science: EpiBone’s First Artist in Residence
What is an artist doing working in a cutting-edge science lab? That’s a question I hear almost every time I explain my summer internship at EpiBone. Fortunately, I feel my whole life has been preparing me to answer it. I have always sat firmly at the intersection between art and science. My best subjects in school were the visual arts and the natural sciences, a seemingly unlikely pair. ...

Peptides for Osteoporosis Research
Introduction to OsteoporosisOsteoporosis is a systemic multi-causal skeletal disease that is prone to fractures due to changes in systemic bone mass and microstructure of bone tissue, resulting in increased bone fragility. Osteoporosis is a type of disease that is difficult to cure. According to the etiology, it can be divided into primary osteoporosis, secondary osteoporosis and idiopathic ...

Do You Really Know Hydroxyapatite?
As an important branch of biomedical materials, bioceramics are mainly used to manufacture hard tissue repair devices and artificial organs in vivo, and generally have good biocompatibility. According to the chemical activity in the physiological environment, bioceramics can be divided into three types: Nearly inert bioceramics, only weak or no chemical reaction occurs when exposed to the ...

Dental Problems Often Cause Bad Breath
The Direct Link between Bacterial Plaque, Bad Breath, and Dental problems Bad breath or halitosis, dental decay, periodontal disease, and gingivitis are all caused by the anaerobic bacteria that live in the mouth. Anaerobic means living in the absence of air. These types of bacteria are mostly pathological. Bad breath is the odor produced by bacteria living off food particles, each other and ...

Laser Application in Periodontics
The use of lasers for periodontal treatment has become more complicated because the periodontium consists of both hard and soft tissues. Non-surgical Periodontal Therapy Dental plaque is known as the principal etiologic factor for the inflammatory periodontal disease; therefore, it is evident that treatment of the disease is dependent upon how much the plaque and its retentive factors are ...
