Study identifies key step in spread of drug resistance, opportunity for intervention Spotless surfaces in hospitals can hide bacteria that rarely cause problems for healthy people but pose a serious threat to people with weakened immune systems. Acinetobacter baumannii causes life-threatening lung and bloodstream infections in hospitalized people. Such infections are among the most difficult […]Continue Reading ...
The Staphylococcus aureus bacterium is one of the commonest pathogens and can even cause sepsis. The new antibiotic dalbavancin is very effective against many bacterial pathogens. However, resistance to the antibiotic was seen to develop during the long-term treatment of a patient with an infection caused by an implanted cardiac device. A team of researchers […]Continue Reading ...
Crystal structure of a portion of the HER2 protein. Credit: RCSB PDB Metastatic breast cancers treated with hormone therapy can become treatment-resistant when they acquire mutations in the human epidermal growth factor receptor 2 (HER2) that were not present in the original tumor, reports a team led by scientists from Dana-Farber Cancer Institute and the […]Continue Reading ...
A model of ER Translocation Credit: Penn Medicine Drugs that target BRAF and MEK in cancer have shown promise in treating a subset of melanoma that carries a mutation in the BRAF gene, but drug resistance usually emerges, reversing the benefit of these drugs and limiting the survival of patients. Research has shown tumors have […]Continue Reading ...
Researchers found that widespread, low-intensity use of antibiotics may play more of a role in antibiotic resistance than high-intensity, repeated use by a small fraction of the population The increasing prevalence of antibiotic resistance in the U.S. appears more closely linked with their occasional use by many people than by their repeated use among smaller […]Continue Reading ...
Researchers at the University of Nebraska-Lincoln have found evidence that the epigenetics-based evolution that occurs in complex multicellular species (eukaryotes) is also at play in a species of archaea, which are microscopic, single-celled organisms. Kateryna Kon | Shutterstock The discovery could improve scientists’ ability to explore and answer questions about epigenetic processes in humans. Through […]Continue Reading ...
Credit: CC0 Public Domain Move over Bifidobacterium and Lactobacillus. There’s a new health-promoting gut bacterium in town, and it’s called Akkermansia muciniphila. You will not find its benefits at the bottom of a yogurt cup. But a new study has identified more than one way to nurture its growth in the gut, and offered evidence […]Continue Reading ...
Nearly two thirds of Americans (65%) say antibiotic resistance is a public health problem and a strong majority (81%) say they are concerned that antibiotic resistance will make more infections difficult or impossible to treat and even deadly, according to a national public opinion survey commissioned by Research!America in collaboration with the Infectious Disease Society […]Continue Reading ...
Increased levels of antibiotic resistant bacteria in the environment may have different causes. It could be a consequence of on-site selection from antibiotic residues in the environment, hence promoting the evolution of new forms of resistance. Alternatively, it is simply due contamination by fecal bacteria that often tend to be more resistant than other bacteria. […]Continue Reading ...
Researchers at Osaka University have discovered that polymyxin E-resistant Escherichia coli is widely prevalent among people living in rural Vietnam. Kateryna Kon | Shutterstock Polymyxin E is an antibiotic that is used to prevent the growth of Gram-negative bacteria such as E.coli and Pseudomonas aeruginosa. It is one of only a few remaining drugs that […]Continue Reading ...
Researchers at the University of Pennsylvania have found that two mechanisms used by a subset of melanoma to resist treatment are connected to each other. The finding could pave the way for new approaches to overcome resistance to therapies. Crevis | Shutterstock Scientists were already aware of the two resistance mechanisms, but until now, the […]Continue Reading ...
Researchers at LSTM have used a bioinformatics approach to integrate information from multiple studies on insecticide resistance in mosquitoes and uncovered a number of important resistance mechanisms that had not previously been recognized. In a study published in Nature Communications, Dr Victoria Ingham and colleagues have utilized specialist computer programming to better understand the mechanisms […]Continue Reading ...
Researchers from LSTM have confirmed that using pyrethroid-PBO treated nets to prevent malaria is more effective at killing mosquitoes in areas where there is a high level of resistance to pyrethroids. The distribution of nets treated with pyrethroid insecticides has been very effective in reducing malaria transmission during the past two decades in Africa. However, […]Continue Reading ...
Lifting weights for less than an hour a week may reduce your risk for a heart attack or stroke by 40 to 70 percent, according to a new Iowa State University study. Spending more than an hour in the weight room did not yield any additional benefit, the researchers found. “People may think they need […]Continue Reading ...
Antibiotic resistance is one of the hottest concerns worldwide today and is likely to take back the human civilization to the pre-antibiotic era at this rate. A new report titled “Stemming the Superbug Tide”, has speculated that antibiotic resistant bugs are soon likely to kill over 90,000 Britons over the next three decades if it […]Continue Reading ...
