Fabric Makes Electricity from Movement to Power Wearables
Scientists at Nanyang Technological University, Singapore, have created a wearable fabric that generates electricity from our body movements. The fabric could assist in powering medical wearables and other mobile diagnostic or therapeutic devices. The fabric contains stretchable polymers that generate electricity when bent, pressed, or brushed, based on piezoelectric and triboelectric effects. The fabric is highly robust and can withstand regular crumpling and washing with no loss of performance. So far, the researchers have shown that it can provide a stable supply of energy for up to five months.
Medical wearables hav...

Positron Emission Tomography (PET) in Cardiology
Positron emission tomography (PET) imaging is useful in assessment of myocardial perfusion and viability, atherosclerotic plaque activity as well as cardiac innervation in heart failure. PET is also useful in prosthetic valve endocarditis, endocarditis associated with cardiac implantable electronic devices (CIED), infiltrative cardiomyopathy, aortic stenosis and cardio oncology [1].
PET imaging has superior diagnostic accuracy compared to SPECT (Single Photon Emission Computed Tomography). It has improved spatial and temporal resolution and can measure regional blood flow and has less radiation. In PET, high energy gamma...

A short de novo synthesis of nucleoside analogs
We present a process for rapidly constructing nucleoside analogs from simple achiral materials. Using only proline catalysis, heteroaryl-substituted acetaldehydes are fluorinated and then directly engaged in enantioselective aldol reactions in a one-pot reaction. A subsequent intramolecular fluoride displacement reaction provides a functionalized nucleoside analog. The versatility of this process is highlighted in multigram syntheses of D- or L-nucleoside analogs, locked nucleic acids, iminonucleosides, and C2 ′- and C4′-modified nucleoside analogs. This de novo synthesis creates opportunities for the prepara...

Showering daily — is it necessary?
Do you shower or bathe daily? If you do, you’re not alone.
Approximately two-thirds of Americans shower daily. In Australia it’s over 80%. But in China, about half of people report bathing only twice a week.
In the US, the daily shower tends to start around puberty and becomes lifelong. But have you ever stopped to ask yourself why?
Perhaps your answer is: “because it’s healthier than showering less often.” Think again. For many — perhaps most — the daily shower is more about habit and societal norms than health. Perhaps that’s why the frequency of bathing or showering varies so much from country to country...

Stretchable E-Tattoo for Long-Term Heart Monitoring
Researchers at the University of Texas at Austin have developed a wearable heart monitor which can assess heart health over several days. The research team call the device an “e-tattoo” and claim that its stretchability makes it more comfortable and convenient to wear compared with previously developed devices. The device is the first stretchable, ultrathin sensor that can provide both electrocardiography (ECG) and seismocardiography (SCG) measurements.
For patients suffering from or at risk of heart disease, monitoring their heart health is important. However, getting an ECG exam means that they have to visit their...

The 6 don ’ts of caring for your child’s teeth
Did you know that tooth decay is the most common chronic disease of childhood? And that 40% of children have tooth decay by kindergarten? This is a big deal, not only because of the pain and infection it can cause, but also because children with tooth decay are more likely to miss school and have poorer grades — and because tooth decay is linked to a higher risk of many health problems later in life, including heart disease and premature birth.
Tooth decay is simple to prevent, yet sadly, many families don’t take the steps that are needed.
1. Don’t skip the fluoride. Fluoride is very helpful when it comes to prev...

Now You See Me, Now You Don’t
A 32-year-old man presented to the emergency department complaining of eye pain and decreased vision. He worked for the city and was removing rust and graffiti from a wall with a power washer when the spray ricocheted off the surface and into his eye. He presented with a bottle of the chemical he used, which contained hydrofluoric acid (HF) and other chemicals. He rinsed his eyes with tap water, but experienced persistent decreased vision and pain in both eyes. His exam was remarkable for bilateral injected conjunctiva and excessive tearing.More than 7,000 ocular exposures were reported to U.S. poison control centers pe...

Nanolasers to Shine Light on Things Inside Body
At the Lawrence Berkeley National Laboratory, scientists have created microscopic lasers that may end up being used for imaging inside the body, control of biological activity via optogenetics, and performing novel biological studies on living specimens. The lasers, which are about 5 microns in diameter, smaller than red blood cells, turn infrared light into coherent blue and near-infrared laser light.
They’re made of polymer nanoparticles mixed with sodium yttrium fluoride nanoparticles doped with thulium. Though they were expected to “upconvert” light from a lower to a higher frequency, the particles un...

Using MRI and PET to Detect Early Knee Osteoarthritis
Researchers from Stanford University have developed the first protocol using magnetic resonance imaging (MRI) for detecting early stage knee osteoarthritis (OA) in all joint tissues. Their findingswere recently published inOsteoarthritis and Cartilage. Traditionally, joint tissues are examined separately, and MRI can only assist in monitoring changes in the subchondral bone when the disease has progressed substantially. The group of researchers led by Feliks Kogan, PhD, saw the need to create a technique that could non-invasively assess changes in bone remodeling and adjacent tissues.The researchers studied patients wi...

Fight Aging! Newsletter, April 16th 2018
This study demonstrates that small peptide domains derived from native protein amelogenin can be utilized to construct a mineral layer on damaged human enamel in vitro. Six groups were prepared to carry out remineralization on artificially created lesions on enamel: (1) no treatment, (2) Ca2+ and PO43- only, (3) 1100 ppm fluoride (F), (4) 20 000 ppm F, (5) 1100 ppm F and peptide, and (6) peptide alone. While the 1100 ppm F sample (indicative of common F content of toothpaste for homecare) did not deliver F to the thinly deposited mineral layer, high F test sample (indicative of clinical varnish treatment) formed mainly C...
