New COVID-19 rapid-test technology performs PCR faster than similar tests on the market

For more than 30 years, polymerase chain reaction (PCR) has been the gold standard in molecular diagnostic testing, detecting genetic material, such as those from a virus or from human DNA. But PCR, including reverse transcription polymerase chain reaction (RT-PCR), is mostly done at large, centralized laboratories, not in point-of-care (POC) settings, because its instrumentation is bulky, expensive, takes a […]

Antibiotics affect male and female gut microbiomes differently

In a new study, researchers at Cedars-Sinai found that antibiotics have sex-specific effects on the gut microbiome makeup of male and female laboratory rats. The findings, published in the journal Frontiers in Microbiology, could have implications for using the drugs in humans to treat or prevent bacterial infection. “We found that giving the rats a multidrug antibiotic cocktail resulted in significant […]

Fragile balance in the gut

The presence of probiotics such as lactic acid bacteria changes the environment in the intestine and forces the yeast fungus Candida albicans to change its metabolism, making it less infectious. This way, probiotics can contain or prevent the spread of fungal infections in the gut. Researchers at the Leibniz Institute for Natural Product Research and Infection Biology – Hans Knöll Institute (Leibniz-HKI) […]

Antibiotics after birth affects gut microbes of babies

Treating babies with antibiotics in the first week of life is linked with a decrease in healthy bacteria necessary amongst others to digest milk and an increase in antimicrobial resistance, research suggests. Experts say that clinicians should consider using antibiotics in a way that causes least harm to the newborns microbiome — the community of microbes that live in our […]

Creating universal blood-type organs for transplant

A study published in Science Translational Medicine performed at the Latner Thoracic Surgery Research Laboratories and UHN’s Ajmera Transplant Centre has proved that it is possible to convert blood type safely in donor organs intended for transplantation. This finding is an important step towards creating universal type O organs, which would significantly improve fairness in organ allocation and decrease mortality for patients […]

European Commission approves Vaxneuvance (pneumococcal 15-valent conjugate vaccine) for individuals 18 years of age and older – Merck Inc

Merck Inc., announced that the European Commission (EC) has approved Vaxneuvance (Pneumococcal 15-valent Conjugate Vaccine) for active immunization for the prevention of invasive disease and pneumonia caused by Streptococcus pneumoniae in individuals 18 years of age and older. The approval allows marketing of Vaxneuvance in all 27 European Union (EU) Member States plus Iceland, Norway and Lichtenstein. The use of […]

Can a dangerous microbe offer a new way to silence pain?

Deadly anthrax toxin blocks multiple types of pain in mice, study shows. Anthrax has a scary reputation. Widely known to cause serious lung infections in humans and unsightly, albeit painless, skin lesions in livestock and people, the anthrax bacterium has even been used as a weapon of terror. Now the findings of a new study suggest the dreaded microbe also […]

Parkinson’s protein blueprint could help fast-track new treatments

Researchers have solved a decade-long mystery about a critical protein linked to Parkinson’s disease that could help to fast-track treatments for the incurable disease. The research, published in Nature, has for the first time produced a ‘live action’ view of the protein, called PINK1, in exquisite molecular detail. The discovery explains how the protein is activated in the cell, where it […]

Embryonic cells sense stiffness in order to form the face

Cells in the developing embryo can sense the stiffness of other cells around them, which is key to them moving together to form the face and skull, finds a new study by UCL researchers. In the study of frog embryos, published in Nature, researchers found that embryonic cells can navigate away from soft regions of the embryo and toward harder regions. […]
