Specialized proteins could soak up excess cytokines in COVID-19 patients

One of the defining features of Covid-19 is the excessive immune response that can occur in severe cases. This burst of immune overreaction, also called a cytokine storm, damages the lungs and can be fatal.

Bacterial metabolism of bile acids boosts generation of immune cells, study shows

A Ludwig Cancer Research study has discovered a novel means by which bacterial colonies in the small intestine support the generation of regulatory T cells--immune cells that suppress autoimmune reactions and inflammation.

COVID-19 and type 2 diabetes have shared disease pathways, study finds

Individuals with diabetes are at increased risk for bacterial, parasitic and viral infections. New research published in Endocrine Reviews, a journal of the Endocrine Society, illuminates how intersections of the coronavirus infection (COVID-19) and type 2 diabetes may require new approaches in treatment for hospitalized patients.

UTSW researchers show how vulnerable cells armor themselves against infection

Cells in some of the body's most vulnerable entry routes to bacterial infection buffer themselves when the immune system detects danger by reorganizing the cholesterol on their surfaces, a new study led by UTSW scientists suggests.

Women born by cesarean have greater risk of obesity and diabetes

A new study published in the open-access journal JAMA Network Open in April 2020 suggests that women born by way of a Cesarean section are at higher risk of developing obesity as well as type 2 diabetes mellitus in adult life.

New insights into the building blocks of periodontitis

Porphyromonas gingivalis is a major bacterial pathogen which leads to periodontitis also known as gum disease. In Japan, 80% of adults aged 35 and over suffer from this disease. What's more, P. gingivalis has also been linked to rheumatoid arthritis, cardiovascular disease, pancreatic cancer, and even Alzheimer's disease.

Study: Bangladesh’s surface waters have high levels of antibiotic residues, chemicals

High levels of antibiotic residues, other medicines and chemicals present in Bangladesh's ponds, canals, lakes, rivers and other surface waters are contributing to a spike in antibiotic resistance in the country, says a new study.

Microneedle patches for potential COVID-19 vaccines or therapeutics

The COVID-19 pandemic is spreading over the world, causing panic and illness on a scale unprecedented in one hundred years. Even while the death toll nears 100,000, with over 1.5 million confirmed cases worldwide, public health experts and medical professionals are battling it using all the weapons available. Unfortunately, these are all too few.

Ai used to detect COVID-19 pneumonia

Coronaviruses have 'spilled over' to human populations throughout history, causing respiratory illnesses, often associated with pneumonia. The severe acute respiratory syndrome (SARS), which emerged in 2002 in China, and the Middle East Respiratory Syndrome (MERS), which was first seen in Saudi Arabia in 2012, are similar to the current global pandemic spreading worldwide, the coronavirus disease (COVID-19).

Spanish study shows infections in children occur early in COVID-19 epidemics

With the spread of COVID-19, scientists are finding out more about the disease. One major aspect that is being studied is how the virus affects children. A new report from Spain, published in the journal JAMA Pediatrics in April 2020, shows that pediatric populations are infected early in the epidemic and that about 10% of those with symptoms suggestive of infection test positive. Severe infection can also occur among children, requiring hospitalization and intensive care.

Vaginal bacteria linked to premature birth

A new study published in the journal Frontiers in Microbiology in April 2020 reports that women who deliver early are more likely to have a greater variety of bacteria in their birth canals. The research also highlights specific bacteria that are associated with premature birth. This knowledge could help design tests to screen for high-risk pregnancies.

Personalized biohybrid microswimmers for therapeutic cargo delivery

Tiny biohybrid robots on the micrometer scale can swim through the body and deliver drugs to tumors or provide other cargo-carrying functions. The natural environmental sensing tendencies of bacteria mean they can navigate toward certain chemicals or be remotely controlled using magnetic or sound signals.
