Tackling Alzheimer ’s Biomarkers Using Machine Learning: Interview with IQuity CEO, Dr. Chase Spurlock
Losing one’s memories, and therefore one’s identity, must be a terrifying experience. With a global estimate of almost 50 million people living with dementia, predicted to rise to more than 130 million by 2050, the burden of Alzheimer’s and dementia are indisputable. While there are still no approved drugs for the treatment of Alzheimer’s, there is an urgency for developing diagnostic tests and the identification of biomarkers that enable the early detection of the disease. In light of this need, diagnostic technology company IQuity (pronounced I-Q-witty) has recently received a grant from the Natio...

New Technique Allows for Live Retinal Cell Imaging
Researchers at the National Eye Institute in the U.S. have developed a retinal imaging technique that reveals live neurons, blood vessels, and epithelial cells within the retina. The method involves combining adaptive optics and angiography, and allows the researchers to view complex units of cells that interact in the outer edge of the retina. As this retinal region is involved in a range of diseases, including atherosclerosis, age-related macular degeneration (AMD), and Alzheimer’s disease, the researchers hope that the technique could help with diagnosis and disease monitoring. “For studying diseases, there&...

The EyeQue VisionCheck personal vision tracker snaps onto the screen of a smartphone and the user simply places it against the eye to perform the testing. The accompanying app displays various images on the screen and while the user looks at those, an internal motor rotates a series of lenses that work together to measure the eye’s focus and astigmatism, and so the refractive error. A special tool built into the app also helps to measure the distance betwee...

Personalized Oxygen Releasing Insoles for Diabetic Foot Ulcers
Diabetic foot ulcers are common maladies that are difficult to heal. In many cases, a total-contact cast is put on the leg with the ulcer to take the pressure off of the bottom of the foot, helping it to heal. While this is effective, supplying oxygen to the ulcer also helps it to heal. This is difficult to do when a patient wears a cast, but researchers at Purdue University have come up with a solution that just might work. The research team has developed special insoles that contain pockets of oxygen near the site of the ulcer. These reservoirs slowly release the oxygen gas onto the insole, and are designed to be used al...

Nanoneedle Skin Patch to Inject Drugs Into Cells
Delivering drugs directly into skin cells using microscopic nanoneedles may allow for highly effective treatment of skin conditions without injuring the cells that are treated. Silicon nanoneedles have been developed in the past that can do such a trick, but they’re stiff and can be painful, in addition to quickly losing their effectiveness. This is because the nanoneedle arrays are normally placed on rigid silicon wafers. “To tackle this problem, we developed a method that enables physical transfer of vertically ordered silicon nanoneedles from their original silicon wafer to a bio-patch,” said Chi Hwan...

The word “paralysis” is starting to lose its gloomy permanence, as researchers at top-end institutions around the world have been getting some people back on their legs who were previously thought to have to spend the rest of their lives in wheelchairs. Well targeted electrical nerve stimulation, coupled with specialized rehab training, has been the key to these achievements. The hits keep coming, though. A team at  École polytechnique fédérale de Lausanne (EPFL) in Switzerland has managed to get three people with serious spinal cord injuries to walk and to even move their legs without...

23andMe ’s Pharmacogenetic Test Approved by FDA
The FDA has just approved 23andMe’s Personal Genomic Service (PGS) Pharmacogenetic Reports. This marks the first direct-to-consumer test for pharmacogenetics of enzyme variants that may affect the way patients break down medications. Consumers collect their saliva into 23andMe’s testing kit, mail it to the company’s labs, and then receive the results via an online portal. The approved pharmacogenetic assessment system looks for 33 variants of common enzymes that affect medication metabolism, including CYP2C19, CYP2C9, CYP3A5, UGT1A1, DPYD, TPMT, SLCO1B1, and CYP2D6. The full list of variants can be found ...

Transistor Chip for Continuous Monitoring of 3D Cell Cultures
A team led by researchers at the University of Cambridge has developed a 3D “organ-on-a-chip” with a difference – the cells in the device grow within an electrode that allows for continuous electrical monitoring. The researchers have dubbed the device a transistor in a tube, or “Tubistor,” and hope that it can advance knowledge about a variety of diseases, potentially leading to new treatments. Organ-on-a-chip devices are becoming increasingly popular as an alternative to laboratory animal models of disease, and allow researchers to model a variety of organs, specific diseases, and test new tr...

myLotus Hormone Monitor for Fertility Tracking Cleared in Europe
Concepta Plc, a company based in Bedfordshire, UK, won the European CE Mark for its myLotus hormone monitoring product. Designed to help women identify when their most fertile days are, myLotus measures hormonalnlevels and keeps track of their changes over time. It is being unveiled for the first time this weekend at the Fertility Show in London. The system consists of a measuring device, tests strips that are inserted into it, and an app that displays the data and helps to analyze it. The woman simply dips the test strip into a urine sample and sticks it into the reader. After a few weeks, a pattern emerges and ...

Nanoparticles and Microneedles for Painless Vaccinations
At Leiden University in The Netherlands, research is being done on making vaccinations easier and more effective. Currently, needles are commonly used and no one, particularly children, is happy about that. Microneedles patches have been developed in the past, but while they’re effective in some applications, they suffer from many limitations. At Leiden University one approach is combining nanoparticles, that are encapsulating a vaccine, with microneedles. This will hopefully result in high efficiency, general purpose method for painlessly delivering vaccinations. It has been shown that properly constructed vaccine ...
