Key ingreduent of Madagascar “Miracle Cure” Artemisia Annua to be tested for COVID-19.

The Max Planck Institute of Colloids and Interfaces, Potsdam (Germany) will collaborate with ArtemiLife Inc., a US based company and medical researchers in Denmark and Germany to test Artemisia annua plant extract and artemisinin derivatives in laboratory cell studies against the novel coronavirus disease (COVID-19).

Currently, there are no effective treatments against COVID-19. Medications commonly used against malaria or Ebola, as well as antiviral drugs, are being considered for repurposing. Herbal treatments used in Traditional Chinese Medicine were explored to treat coronavirus infections during the SARS-CoV and MERS-CoV outbreaks. Initial studies in China showed the alcoholic extract of sweet wormwood (Artemisia annua) was the second most potent herbal medicine used on the 2005 SARS-CoV.

“I am excited about the international collaboration of academic and private sector scientists to conduct cell study testing of Artemisia annua against coronavirus.” said Professor Peter H. Seeberger, Director at the Max Planck Institute of Colloids and Interfaces in Potsdam.

O,.o I used vitamin c and a probiotic it seemed to work well. I also had a flu shot for the year. Besides eating well and staying healthy not much is needed. It is sorta like the flu as much as I can see. I am no doctor but that worked for me.

Korean scientists claim that a lactic acid bacteria from sea buckthorn berries, could potentially inhibit the proliferation of SARS-CoV-2 by repressing purine activation.

Lactobacillus species in the gut microbiota have been found to block pro-inflammatory cytokines to inhibit harmful bacteria like Helicobacter pylori. While studying similar mechanisms against bladder inflammation (cystitis) causing E. coli, a team led by Professor Hana Yoon of Ewha Womans University Medical Center in Seoul, found abundant amounts of Lactobacillus gasseri present in the fermented extracts of sea buckthorn berries.

The probiotic has now been found to repress the activation of purine thereby preventing the SARS-CoV-2 from proliferating. Purine is an important compound required for nucleotide formation. Recent studies have found that the new coronavirus attacks purines in order to form its spike proteins and invade normal cells. The Korean team also found that the berries had several antioxidants, minerals, amino acids, and two other bacteria, Streptococcus thermophilus, and Lactobacillus rhamnosus that use the same binding site as that of SARS-CoV-2.

The coronavirus that originated in Wuhan, China, swept the world fast and furiously — and we’re barely starting to experience the first wave of the pandemic. However, to biologists and virologists, the sudden appearance of the coronavirus wasn’t surprising. It is simply a natural consequence of humans disturbing ecosystems in equilibrium and wildlife trade, something that we’ve done at an increasing rate with each passing decade.

Pandemics such as COVID-19 might become increasingly frequent as humans continue unabated on their course to expand their range at the expense of wildlife.

High rates of deforestation in Asia over the last four decades have prompted many scientists to sound the alarm, warning the world of the risk of dangerous microorganisms migrating to humans.

‘Through advances in medical devices and synthetic biology, DARPA’s new Advanced Acclimation and Protection Tool for Environmental Readiness (ADAPTER) program aims to develop a travel adapter for the human body, an implantable or ingestible bioelectronic carrier that can provide warfighters control over their own physiology. The integrated system will be designed to entrain the sleep cycle – either to a new time zone or back to a normal sleep pattern after night missions – and eliminate bacteria that cause traveler’s diarrhea after ingestion of contaminated food and water,’ reads a DARPA statement on the new device.”

The adapter is meant to regulate sleep patterns and protect against diarrhea.

Not long ago nanotechnology was a fringe topic; now it’s a flourishing engineering field, and fairly mainstream. For example, while writing this article, I happened to receive an email advertisement for the “Second World Conference on Nanomedicine and Drug Delivery,” in Kerala, India. It wasn’t so long ago that nanomedicine seemed merely a flicker in the eyes of Robert Freitas and a few other visionaries!

But nano is not as small as the world goes. A nanometer is 10−9 meters – the scale of atoms and molecules. A water molecule is a bit less than one nanometer long, and a germ is around a thousand nanometers across. On the other hand, a proton has a diameter of a couple femtometers – where a femtometer, at 10−15 meters, makes a nanometer seem positively gargantuan. Now that the viability of nanotech is widely accepted (in spite of some ongoing heated debates about the details), it’s time to ask: what about femtotech? Picotech or other technologies at the scales between nano and femto seem relatively uninteresting, because we don’t know any basic constituents of matter that exist at those scales. But femtotech, based on engineering structures from subatomic particles, makes perfect conceptual sense, though it’s certainly difficult given current technology.

The nanotech field was arguably launched by Richard Feynman’s 1959 talk “There’s Plenty of Room at the Bottom.” As Feynman wrote there.
