Researchers at the University of Arizona are developing a COVID-19 testing method that uses a smartphone microscope to analyze saliva samples and deliver results in about 10 minutes.

The UArizona research team, led by biomedical engineering professor Jeong-Yeol Yoon, aims to combine the speed of existing nasal swab antigen tests with the high accuracy of nasal swab PCR, or polymerase chain reaction, tests. The researchers are adapting an inexpensive method that they originally created to detect norovirus—the microbe famous for spreading on cruise ships—using a smartphone microscope.

They plan to use the method in conjunction with a saline swish-gargle test developed by Michael Worobey, head of the UArizona Department of Ecology and Evolutionary Biology and associate director of the University of Arizona BIO5 Institute.

The team’s latest research using —done in collaboration with Kelly A. Reynolds, chair of the Department of Community, Environment and Policy in the UArizona Mel and Enid Zuckerman College of Public Health—is published today in Nature Protocols.

“We’ve outlined it so that other scientists can basically repeat what we did and create a norovirus-detecting device,” said Lane Breshears, a biomedical

‘Organs-on-a-chip’ system sheds light on how bacteria in the human digestive tract may influence neurological diseases

In many ways, our brain and our digestive tract are deeply connected. Feeling nervous may lead to physical pain in the stomach, while hunger signals from the gut make us feel irritable. Recent studies have even suggested that the bacteria living in our gut can influence some neurological diseases.

Modeling these complex interactions in animals such as mice is difficult to do, because their physiology is very different from humans’. To help researchers better understand the gut-brain axis, MIT researchers have developed an “organs-on-a-chip” system that replicates interactions between the brain, liver, and colon.

Using that system, the researchers were able to the influence that microbes living in the gut have on both healthy brain tissue and derived from patients with Parkinson’s disease. They found that short-chain fatty acids, which are produced by microbes in the gut and are transported to the brain, can have very different effects on healthy and diseased brain .

“While short-chain fatty acids are largely beneficial to human health, we observed that under certain conditions they can further exacerbate certain brain

Researchers with the Kansas City Veterans Affairs Medical Center and North Dakota State University have designed a new way to deliver pancreatic cancer drugs that could make fighting the disease much easier. Encapsulating cancer drugs in nanoparticles shows potential to target tumors more effectively and avoid danger to other parts of the body.

The study results appeared in the Jan. 4, 2021, issue of the journal Molecular Pharmaceutics.

Study author Dr. Sushanta Banerjee, a researcher with the Kansas City VA and University of Kansas medical centers, explains that this technology has the potential to drastically improve Veterans’ care. “Veteran health care will benefit immensely from such therapeutic models, as they are effective in delivering the drug to the site without any toxic side effects [and with] minimal dosing. Once ready for patient use, this technique will reduce the number of doses required by a patient as well as effectively hinder the progression of the tumor.”

Pancreatic ductal adenocarcinoma is the most aggressive form of pancreatic cancer. It is one of the leading causes of death from cancer

‘Smart’ cartilage cells programmed to release drugs when stressed

Researchers at Washington University School of Medicine in St. Louis have engineered cartilage cells to release an anti-inflammatory drug in response to stresses such cells undergo when they are compressed during weight bearing and movement. Here, the cell, called a chondrocyte, is stimulated with a very small glass pipette, about 1/5 the diameter of a human hair. When these cells undergo compression, they release the drug that combats inflammation. Credit: Guilak lab

Working to develop new treatments for osteoarthritis, researchers at Washington University School of Medicine in St. Louis have genetically engineered cartilage to deliver an anti-inflammatory drug in response to activity similar to the bending of a knee or other motions that put stress on joints.

Among the early symptoms of osteoarthritis is pain in response to such movements—motions that involve the so-called mechanical loading of a joint. Joint pain that accompanies bending or lifting can make it difficult to perform normal activities. But by altering genes in in the laboratory, the researchers have been able to program them to respond to the associated with movement and weight-bearing by producing a to combat inflammation.

The study is published online Jan. 27 in the journal
