Ultrathin Conductive Films for Wearables are Flexible and Durable
Researchers at UCLA created ultrathin films that are just 10 nanometers thick, but which can maintain electrical conductivity, flexibility, and strength. The molecules within the films are held together by non-bonding van der Waals forces, making them highly pliable, and the numerous sheets within the films are able to slide over each other without breaking apart. The films are also breathable and are permeable to water and air. These properties mean that the films are highly suited as a component for health-related wearables, and the resulting wearable creations can easily conform to the shape of the body part they are ap...

Incompetence, Incompetents, and Incontinence
I clearly have neglected my poor blog. There have been very few new posts in the past year. I ' ll chalk it up to some patois of melancholy, sloth, feeling stuck in Purgatory, SARS-CoV-2 (mainly the fear of it...we have remained free of illness, thank Heavens!), and maybe a touch of writer ' s block. But even in its tepid twilight of quasi-existence, people do still read my various random thoughts. I know because I continue to track such things. It has come to my attention that anold post from over a year ago has taken the fancy of some IT folk:In fact, word has reached me that they were not amused. " Dalai is calling...

Superhydrophic “Nanoflowers” for Biomedical Applications
Researchers from Texas A&M University have developed new nanomaterial with superhydrophobic properties. Their recent publication demonstrates that by controlling atomic-scale defects in their nanomaterial, they could use it to repel water and blood on glass, paper, and other common materials. This exciting development can lead to self-cleaning biosensors and anti-fouling surfaces.
Various self-cleaning materials have been developed, but these require their surface chemistry or topography to be modified, which is not amenable to various materials. The new approach can be applied to various substrates, including glass...

University of Missouri Research Reactor Now Supplying Iodine-131 for Thyroid Treatment
Medical radioisotopes are widely used in cancer treatment, but their production has been hampered to the point that obtaining them has become a challenge. The lack of Technetium-99m is probably the most widely known, but there’s also a shortage of Iodine-131 (I-131), a radioisotope commonly used for diagnosing and treating thyroid conditions because the thyroid absorbs iodine naturally.
Things are now looking up as the University of Missouri Research Reactor (MURR), a 10 megawatt reactor, has just produced the first commercial batch of I-131. International Isotopes, Inc. is the buyer and distributor. This is t...

Electronic Synthetic Cells Small Enough for Injections
If injectable autonomous robots are to be used in medicine, they must be tiny and capable of being manufactured by the million. They must also have some kind of electronics inside for diagnostic or therapeutic capabilities. Researches at MIT have developed a method for producing so-called “syncells,” or synthetic cells, that can process data inputs and produce outputs, and that are small enough to be injectable into the bloodstream.
The manufacturing process is called “autoperforation,” and it involves carefully managing how graphene cracks so that it can encapsulate a tiny piece of electronics. At ...

Isagenix. – Diet Review
Conclusion – Does Isagenix Work?
Isagenix Isalean’s shake is marketed well, but it’s loaded with sugar and calories. There’s also a lot of protein added, but once you research what kinds of ingredients are included, you realize it’s not a quality meal replacement. The protein added is cheap and can be found for a reduced price elsewhere. Many customers have also complained about the taste, lack of weight loss, and the hard to drink consistency.
There are better options which have only 1 gram of sugar, no added fructose, only high quality whey protein, and great reviews to back up their weight loss claims. T...

U.S. to Get Its Own Supply of Radioisotopes Thanks to Approval of RadioGenix System
A good deal of advanced medical imaging to spot cancer tumors, and help to diagnose coronary artery disease and other conditions, relies on injecting radioisotopes into the body whose location can be tracked. The most common is technetium-99m (Tc-99m), but it has been in short supply because there are only a few nuclear power stations around the world making it as a byproduct of highly-enriched uranium, but new technologies are maturing that can help avoid many of the radioisotope sourcing issues that exist to prevent nuclear weapon proliferation and guarantee safety.
The FDA and the Nuclear Regulatory Commission (NRC) of ...

Biodegradable Pressure Sensor Doesn ’t Need to be Removed After Implantation
Researchers at the University of Connecticut have developed a biodegradable pressure sensor that can be implanted in the body and help clinicians to monitor a variety of conditions over extended periods of time. What makes this sensor different from existing ones is that it doesn’t need to be removed and will eventually dissolve in the body, eliminating the risk of infection and the longer recovery associated with an invasive surgical procedure to remove a sensor.
Clinicians can use implantable pressure sensors to monitor a variety of health conditions, including brain swelling as in hydrocephalus, chronic lung diseases,...

Antibacterial Nanoscale Etching of Stainless Steel Surfaces
At Georgia Tech, researchers have developed a way of etching stainless steel surfaces so finely that bacteria that come in contact with them end up being pierced and killed. Interestingly, because of the physiological differences between cell types, mammalian cells don’t seem to be significantly impacted by these surfaces. This may point to interesting applications for the technology beyond just treating commonly used surfaces in hospitals and clinics, such as medical implants that resist the formation of bacterial biofilms.

Giving Back: RAD-AID
Question: What do airships, 747 ’s, William Shatner, Radiology, and giving back have in common?Answer: RAD-AID International!Let me explain …A few years ago, I decided to bail out of the rat-race of private practice. My original goal was to retire altogether, but it seemed more reasonable to ease out slowly, maintain health insurance and some shred of income, and have something to do, at least periodically. And so I started out working 26 weeks per year, and now I ’m down to 22 weeks. Which leaves 30 weeks that need to be filled. I had originally thought I would ramp up my writing, but somehow that hasn’t happened;...

Flavors of DVI
I just completed (a rather long) Day 4 at Aga Khan Hospital, here in Dar es Salaam, Tanzania (in case you didn ' t know where I was). As usual, time flies when you ' re having fun, and I really am enjoying my time here.Today was a day of many hats. In the morning, I played " real doctor " and attended an OB Gyn lecture series beamed over from the Aga Khan University Hospital in Nairobi:The full title was " Female Sexual Dysfunction and its Effects upon Fertility " and it was quite well done. While the lecture will have little impact upon my medical practice, I ' m trying to get the staff used to me hanging around, and I ha...

Lantheus Announces First Technetium-99m Isotope Generator from Low Enriched Uranium
Last week the American Medical Isotopes Production Act of 2011 (AMIPA) finally became law, and America is planning on curtailing the use and export of highly enriched uranium (HEU) for the production of medical isotopes.Coinciding with President Obama’s signing of the act into law, Lantheus Medical Imaging, Inc. of N. Billerica, MA, is now making available its LEU TechneLite generator, the first technetium-99m (Tc-99m) generator in the US that uses molybdenum-99 (Mo-99) sourced from at least 95% low enriched uranium.Read More (Source: Medgadget)
