Johnson & Johnson ‘pretty confident’ it can develop coronavirus vaccine

Posted by in category: biotech/medical

Drugmaker Johnson & Johnson is “pretty confident” that it can create a vaccine to combat the deadly coronavirus, an exec said Monday.

Paul Stoffels, the company’s chief scientific officer, said it began working on a vaccine two weeks ago — and is hopeful that it can be developed within months, CNBC reported.

“We have dozens of scientists working on this so we’re pretty confident we can get something made that will work and stay active for the longer term,” Stoffels told CNBC’s “Squawk Box.”

Gilead Sciences Offers Experimental Drug for Coronavirus Treatments, Testing

Posted by in category: biotech/medical

Gilead Sciences said it is sending an experimental antiviral drug to China for emergency treatment of coronavirus patients as well as testing to see if it works against the virus.


Gilead Sciences Inc. said on Friday that it had provided doses of an experimental antiviral drug to doctors for the emergency treatment of a small number of patients infected by the new coronavirus.

Understanding the Novel Coronavirus (2019-nCoV)

Posted by in category: biotech/medical

What is Coronavirus According to the World Health Organization[i], Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV).

What is 2019 Novel Coronavirus (2019-nCoV) The 2019 Novel Coronavirus (2019-nCoV) is a new strain of coronavirus that was first identified during an investigation into an outbreak in Wuhan, China. It’s important to note that how easily a virus spreads person-to-person can vary. Some viruses are highly contagious, while other viruses are less so. Investigations are ongoing to better understand the transmissibility, severity, and other features associated with 2019-nCoV, but there are indications that person-to-person spread is occurring[ii].

Know the Coronavirus Symptoms According to the CDC, patients with confirmed 2019-nCoV infections have reported mild to severe respiratory illnesses with symptoms including:

Research Teams Sequence Entire Coronavirus Genome To Understand Origin And Virulent Properties

Posted by in categories: biotech/medical, health

Researchers at the Institut Pasteur in France have become the second monitoring team in the world to sequence the entire novel coronavirus (2019-nCoV) genome in an effort to better understand its origin and virulent properties.

Nearly 8,000 reported cases and hundreds of deaths have been reported in at least 19 countries since the outbreak began in Wuhan, China, last December, prompting the World Health Organization yesterday to declare a public health emergency after evidence of human-to-human transmission had surfaced. International healthcare experts have since prioritized research surrounding 2019-nCoV in an effort to understand and tame the global outbreak.

“Sequencing the genome of pathogens is crucial for the development of specific diagnostic tests and the identification of potential treatment options,” explained Sylvie van der Werf, director of the National Reference Center (CNR) for Respiratory Viruses at the Institut Pasteur, in a statement.

Surveillance of Bat Coronaviruses in Kenya Identifies Relatives of Human Coronaviruses NL63 and 229E and Their Recombination History

Posted by in categories: biotech/medical, genetics, surveillance

Circa 2017 Bats harbor a large diversity of coronaviruses (CoVs), several of which are related to zoonotic pathogens that cause severe disease in humans. Our screening of bat samples collected in Kenya from 2007 to 2010 not only detected RNA from several novel CoVs but, more significantly, identified sequences that were closely related to human CoVs NL63 and 229E, suggesting that these two human viruses originate from bats. We also demonstrated that human CoV NL63 is a recombinant between NL63-like viruses circulating in Triaenops bats and 229E-like viruses circulating in Hipposideros bats, with the breakpoint located near 5′ and 3′ ends of the spike (S) protein gene. In addition, two further interspecies recombination events involving the S gene were identified, suggesting that this region may represent a recombination “hot spot” in CoV genomes. Finally, using a combination of phylogenetic and distance-based approaches, we showed that the genetic diversity of bat CoVs is primarily structured by host species and subsequently by geographic distances.

Reversal of ageing- and injury-induced vision loss

Posted by in categories: biotech/medical, genetics, life extension

If you are interested in superlongevity, then I have something that you must read. I have previously recommended a book by Dr. David Sinclair called Lifespan. Here I am recommending a research paper that discusses one of the critical experiments in epigenetic age reversal. Normally I would read a paper first before recommending it. However, I think this is a blockbuster, and it’s over 50 pages, so I can’t wait till my slow eyes finish before passing this on. Here is an excerpt:

Age reversal!

The primary research scientist is Yuancheng Lu.

Anticancer Activity Discovered in Dozens of Existing Noncancer Drugs

Posted by in categories: biotech/medical, genetics

Surprising findings could springboard the development of new anticancer drugs, or potentially even directly repurpose existing drugs for cancer therapy.


Drugs that are currently used to treat a wide range of conditions such as diabetes, inflammation, alcoholism, and even canine arthritis, can also kill laboratory-grown cancer cells, according to the results of a study by scientists at the Broad Institute of MIT and Harvard and Dana-Farber Cancer Institute. Using a molecular barcoding technology called PRISM (profiling relative inhibition simultaneously in mixtures) the researchers were able to screen thousands of existing drug compounds against different types of cancer cell lines. The results identified 49 compounds with previously unrecognized anticancer activity. The researchers say their surprising findings, which highlighted novel anticancer mechanisms and targets, could feasibly be used to springboard the development of new anticancer drugs, or potentially even directly repurpose existing drugs for cancer therapy.

Trojan Horse Nanoparticle Eats Up Plaque to Clear Arteries

Posted by in categories: biotech/medical, engineering, food, nanotechnology

A hungry nanoparticle that enters your body and eats away at your insides sounds like a nightmare straight out of a Michael Crichton novel. In fact, it could be a future defense against heart attacks, strokes, and potentially other fatal diseases — as strange as that might initially sound.

Developed by scientists at Michigan State and Stanford universities, the innovative new “Trojan Horse” nanoparticle works by munching away portions of the plaques responsible for heart attacks. In a proof-of-concept demonstration, the researchers recently showed that their specially developed nanoparticle is able to accurately home in on atherosclerotic plaque, which is responsible for atherosclerosis, one of the leading causes of death in the United States.

“What the nanotherapy does is it enters inflammatory monocytes [a type of white blood cell] in the blood, and carries them into the plaque — hence the ‘Trojan Horse’ label — where they become macrophages, and stimulatesthose and other macrophages in plaque to devour cellular debris,” Bryan Smith, associate professor of biomedical engineering at MSU, told Digital Trends. “This ‘taking out the trash’ attribute stabilizes the plaque with minimal side effects.”
