Stanford University lab repurposes scuba gear into reusable PPE
Posted by Omuterema Akhahenda in categories: bioengineering, biotech/medical
Bioengineering professor Manu Prakash runs a lab at Stanford University that uses low-cost materials to create effective scientific devices. He returned from a recent vacation with some scuba gear — as well as a cold. While he tested negative for COVID-19, he stayed cautious and self-quarantined for two weeks. During that time, he reworked his snorkel mask into a reusable face shield for healthcare providers by combining it with a medical-grade filter. Dubbed the Pneumask, Prakash and his team tested the device and sent their findings to the FDA, which cleared it as a face shield or surgical mask, but not as a respirator. According to The Washington Post, this decision was made so that the masks could go out to healthcare workers immediately, as clearing the device as a respirator would require more time.
Manu Prakash and his team at Stanford University have turned a standard scuba mask into a reusable medical face mask.

Gut microbes influence how rat brains react to opioids
Posted by Xavier Rosseel in categories: biotech/medical, neuroscience
“Like you often have to do in science, we first hit the problem with a hammer to see how the system breaks, then backtrack from there,” Simpson said.
By that she means that in order to determine if the gut microbiome influenced drug addiction, they first needed to compare an organism with a normal gut microbiome to one without. To do that, the researchers gave some rats antibiotics that depleted 80 percent of their gut microbes. All of the rats — those with and without gut microbes — were dependent on the prescription opioid pain reliever oxycodone. Then some of the rats from each group went into withdrawal.
“To me, the most surprising thing was that the rats all seemed the same on the surface,” George said. “There weren’t any major changes in the pain-relieving effect of opioids, or symptoms of withdrawal or other behavior between the rats with and without gut microbes.”
It wasn’t until the team looked at the rats’ brains that they saw a significant difference. The typical pattern of neuron recruitment to different parts of the brain during intoxication and withdrawal was disrupted in rats that had been treated with antibiotics, and thus lacked most of their gut microbes. Most notably, during intoxication, rats with depleted gut microbes had more activated neurons in the regions of the brain that regulate stress and pain (periaqueductal gray, locus coeruleus) and regions involved in opioid intoxication and withdrawal (central amygdala, basolateral amygdala). During withdrawal, microbe-depleted rats had fewer activated neurons in the central amygdala, as compared to rats with normal gut microbiomes.

Dr. Fauci backed controversial Wuhan lab with millions of U.S. dollars for risky coronavirus research
Posted by Brent Ellman in categories: biotech/medical, health
“just last year, the National Institute for Allergy and Infectious Diseases, the organization led by Dr. Fauci, funded scientists at the Wuhan Institute of Virology and other institutions for work on gain-of-function research on bat coronaviruses.
In 2019, with the backing of NIAID, the National Institutes of Health committed $3.7 million over six years for research that included some gain-of-function work. The program followed another $3.7 million, 5-year project for collecting and studying bat coronaviruses, which ended in 2019, bringing the total to $7.4 million.”

238 inmates test positive for coronavirus at Sterling prison, the largest known outbreak in Colorado
Posted by Brent Ellman in categories: biotech/medical, law enforcement
A Colorado prison is now the site of the state’s largest confirmed COVID-19 outbreak as mass testing confirms that 238 inmates at Sterling Correctional Facility have the virus.
The number of positive cases at the facility spiked as more results from the 472 tests administered last week became available. Of those tested, half were positive. Sixteen tests were inconclusive, 216 were negative and two were still pending Tuesday afternoon, Colorado Department of Corrections spokeswoman Annie Skinner said in an email.
Four of the sick inmates were in the hospital Tuesday afternoon, Skinner said.

San Francisco Food Banks Get a Surprise Delivery of $2 Million of Wagyu Steak
Posted by Omuterema Akhahenda in categories: biotech/medical, finance, food
Idaho-based beef purveyor Snake River Farms is donating 35,000 10-ounce steaks to Bay Area food banks, with a total value of $2 million, the San Francisco Chronicle reports. It’s part of a larger initiative the company announced last week, which will send $8 million worth of its American wagyu to cities around the country to feed hospital workers, laid-off restaurant staff and other communities affected by the Covid-19 crisis. Snake River is relying on regional distribution partners in Los Angeles, Seattle, New York and San Francisco to help them get their donation to nonprofits.
With restaurants shut down, Snake River Farms is giving its premium beef a good home.
