NewsStudy reveals how dextran sulfate sodium-induced colitis exacerbates periodontitis
A new study provides strong evidence that the NOX2/ROS axis plays a key role in the exacerbation of periodontitis in the presence of colitis.

NewsSea buckthorn extract exerts anti-free radical, antibacterial and whitening effects on skin
Sea buckthorn flavonoids exhibited excellent antimicrobial, anti-inflammatory and whitening effects in a new study. The inhibitory effect of sea buckthorn flavonoids on Propionibacterium acnes were assessed by plate antibacterial assays.

NewsProposed cuts to foreign aid could result in millions of HIV deaths, new modelling study estimates
New modelling analysis suggests that proposed funding cuts by major donor countries to foreign aid could undo decades of progress made to end HIV/AIDS as a public health threat and new infections and deaths could surge back to levels not seen since the early 2000s.

NewsBreakthrough as researchers discover new class of antibiotics
Researchers have identified a strong candidate to challenge even some of the most drug-resistant bacteria on the planet: a new molecule called lariocidin.

NewsScientists develop eco-friendly, nylon-like plastic using microorganisms
Scientists have developed microbial strains through systems metabolic engineering to produce various eco-friendly, bio-based poly(ester amide)s from glucose derived from biomass sources such as waste wood and weeds.

NewsHepatitis B: new rapid diagnostic test to halt mother-to-child transmission
Scientists have assessed a new rapid diagnostic test to identify pregnant women at elevated risk of transmitting hepatitis B to their babies. This diagnostic tool could help eliminate hepatitis B by preventing mother-to-child transmission during childbirth.

NewsCorrecting imbalance with the gut microbiota after stroke could reduce brain inflammation
An imbalance in ligands, which are molecules produced by the body and the gut microbiota, can affect a key receptor protein that plays a role in brain inflammation after stroke, according to researchers.

NewsMeasles elimination versus eradication: The difference explained
As of March 13, the CDC has confirmed 301 cases of measles as well as the death of a child in Texas. Amira Roess, an epidemiologist and professor of global health, clarifies the benefits of vaccinating children and adolescents against measles.

NewsAntibiotic exposure in infancy may boost Type 1 diabetes risk - but microbiota can help
Exposure to antibiotics during a key developmental window in infancy can stunt the growth of insulin-producing cells and may boost risk of diabetes later in life. But the research pinpoints specific microbes that may help those critical cells proliferate in early life.

NewsThe gut microbiota-metabolites-brain axis mediates social behavior dysfunction following anaesthesia
New research shows that the anaesthetic Sevoflurane (Sev) influences social functioning via the gut-brain axis, with microbiota-derived bile acids serving as critical mediators in this pathway.

NewsTadpoles try to flee dangerous virus in their pond by growing much faster than normal
A new study shows that larvae of wood frogs respond to the presence of a deadly ranavirus by growing and maturing precociously. In response to ranavirus, tadpoles change their growth, development, and resource allocation, which may help them tolerate the energetic demands of infection or escape risky environments to avoid infection.

NewsC. diff uses toxic compound to fuel growth advantage
The pathogen C. diff — the most common cause of health care-associated infectious diarrhea — can use a compound that kills the human gut’s resident microbes to survive and grow, giving it a competitive advantage in the infected gut.

NewsGrowing body of evidence links HPV with heart disease
In addition to causing several types of cancer, human papillomavirus (HPV) appears to bring a significantly increased risk of heart disease and coronary artery disease, according to a study.

NewsProbe into human cervical stem cells shows lactic acid bacteria can prevent cervical cancer
Researchers have revealed the identity and differentiation process of human cervical stem cells in a world first study. The results showed that lactic acid bacteria can inhibit the development of cervical cancer.

NewsResearchers achieve de novo biosynthesis of plant lignans using synthetic yeast consortia
Researchers have achieved the biosynthesis of the antiviral ingredient lignan glycoside in yeast Saccharomyces cerevisiae. By mimicking the spatial and temporal regulation of plant biosynthesis, they designed a system with obligated mutualism, enabling metabolic division of labor among different yeast strains.

NewsSusceptibility to bovine TB in cattle traced to key genes
A new study identifying genetic factors contributing to bovine tuberculosis (bTB) susceptibility has found several key genes and pathways involved in the bovine response to Mycobacterium bovis, the causative agent of the disease in cattle.
