Developing more sensitive cancer diagnostics
Detecting cancer in the body usually happens when the disease is already well underway to being mortally dangerous. Although there’s a myriad of cancers and ways to detect them, diagnostic tests typically look for biomarkers produced by tumors. And the bigger the tumor, the more biomarkers it releases, so the bigger it is the easier it is to detect. To get at the disease at its earlier stage, it would be useful to detect processes within ce...
Kinesthetic feedback improves control of prosthetic devices
Researchers at Cleveland Clinic have introduced a system that recreates so-called kinesthetic perception and significantly improves the dexterity of individuals using hand prostheses. Their technology involves vibrators that stimulate the muscles that are used to control the movement of prostheses. As the fingers of the device are opened and closed, vibrations are induced, the nature of which reveals to the user where their hand is.
Cystoscope receives FDA 510(k) clearance
UroViu Corporation has announced that its Uro-V single-use diagnostic cystoscopic system has received 510(k) clearance from the US Food and Drug Administration. Additionally, the United States Patent and Trademark Office has issued a patent to UroViu on the Uro-V System. The single-use disposable, semi-flexible, easy-to-use and patient-friendly Uro-V System represents a major advance in diagnostic cystoscopy.
A haemostat spray device that does not cause embolisms
Team Consulting has created Convesaid, a haemostat spray device that eliminates the risk of air embolism when delivering powder haemostats during surgery. Stopping bleeds quickly and efficiently during surgery saves lives and money. A recent study from the British Medical Council found that 30% of speciality inpatient surgeries involved a bleed during the procedure which increased the length of hospital stay (BMC).
Extracellular vesicles could be personalised drug delivery vehicles
Creating enough nanovesicles to inexpensively serve as a drug delivery system may be as simple as putting the cells through a sieve, according to an international team of researchers who used mouse autologous — their own — immune cells to create large amounts of fillable nanovesicles to deliver drugs to tumours in mice. Nanovesicles are tiny sacs released by cells that carry chemical messages between cells. These nanovesicle...
Human skin pigmentation recreated with a 3D bioprinter
A method for controlling pigmentation in fabricated human skin has been developed by researchers from A*STAR’s Singapore Institute of Manufacturing Technology (SIMTech) and the Singapore Centre for 3D Printing (SC3DP) at Nanyang Technological University. In their paper, publishing today in Biofabrication, the team show how they utilise 3D bioprinting to control the distribution of melanin-producing skin cells (melanocytes) on a biomime...
Bringing the bling to improve implants
In a world first, Australian researchers have harnessed the power of diamonds in a breakthrough that could radically improve the way human bodies accept biomedical implants. Researchers from RMIT University have for the first time successfully coated 3D printed titanium implants with diamond. The development is the first step toward 3D printed diamond implants for biomedical uses and orthopaedics - surgical procedures involving the huma...
Brain perceives prosthetic devices as real hands
The human brain can take advantage of brain resources originally devoted to the hand to represent a prosthetic limb, a new UCL-led study concludes. Among people with only one hand, the brain area that enables us to recognise hands can also recognise a prosthetic hand, particularly among those who use a prosthesis regularly, according to the Brain paper. The study provides the first account of how artificial limbs are represent...
Human tissue samples replicate interactions of multiple organs
MIT engineers have developed new technology that could be used to evaluate new drugs and detect possible side effects before the drugs are tested in humans. Using a microfluidic platform that connects engineered tissues from up to 10 organs, the researchers can accurately replicate human organ interactions for weeks at a time, allowing them to measure the effects of drugs on different parts of the body.
Improving mammogram quality
G-ray Medical Sàrl has developed an ultra-high performance detector dedicated to medical applications and in particular mammography. These ultra-high performance detectors will be made in partnership with CSEM, based on G-ray’s latenium technology. Centred on particle-counting X-ray imaging, this unique solution is set to improve the quality of the images obtained from examinations such as breast cancer screening helping earlier dete...
