Modulation of estrobolome may help lower breast cancer risk

Investigating disparities in the composition of the estrobolome, the gut bacterial genes capable of metabolizing estrogens in both healthy individuals and in women diagnosed with estrogen-driven breast cancer may lead to the development of microbiome-based biomarkers that could help mitigate the risk of certain cancers, according to a review paper published April 22 in the JNCI: Journal of the National Cancer Institute.

Macrophages play key role in quick tissue repair

While scientists have known for many years that there are cells living in the cavities surrounding various organs such as the heart, lung and liver, their function has remained unknown. A recent Cumming School of Medicine study examined these cells, and discovered they play an integral role in fast tissue repair. The study was published in the journal Cell this month.

Subtle changes in protein-coding gene may cause different genetic disorders

It has been disorienting to the scientific and medical community as to why different subtle changes in a protein-coding gene causes many different genetic disorders in different patients -- including premature aging, nerve problems, heart problems and muscle problems. no other gene works like this. According to a new study, co-authored by Binghamton University faculty Eric Hoffman, it has to do with cell "commitment."

Researchers determine 3-D structure of RlmN protein from bacteria

The structure of a bacterial RNA-binding protein has been determined in the act of modifying a molecule of RNA -- an achievement that provides researchers with a unique view of the protein's function in action and could lead to clues that would help in the fight against the development of antibiotic-resistant infections.

Important determinants of periodontal disease

Although, bacteria are a critical etiologic factor that are needed to develop periodontal disease, bacteria alone are insuficiente to induce a periodontal disease. A susceptible host is also required, and the host's susceptibility as local and/or general predisposing risk factors, are important determinants of the disease status.

Scientists map core genes involved during DNA uptake in strep bacteria

Bacteria possess the ability to take up DNA from their environment, a skill that enables them to acquire new genes for antibiotic resistance or to escape the immune response. Scientists have now mapped the core set of genes that are consistently controlled during DNA uptake in strep bacteria, and they hope the finding will allow them to cut off the microbes' ability to survive what doctors and nature can throw at them.

Bacteria-derived gut metabolites can affect brain’s myelin content and induce depression-like symptoms

Specific combinations of gut bacteria produce substances that affect myelin content and cause social avoidance behaviors in mice, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published today in the medical journal eLife. This research suggests that targeting intestinal bacteria, or their metabolites, could be one way to treat debilitating psychiatric disorders and demyelinating diseases, like multiple sclerosis.

TNF-alpha protein involved in autoimmune diseases may also promote tissue healing

As its name suggests, inflammatory bowel disease, which afflicts more than 1.6 million Americans, involves chronic inflammation of all or some of the digestive tract. An autoimmune disease known to have a strong genetic component, its symptoms are abdominal cramps, bloody diarrhea, and fever and, sometimes, weight loss. IBD, which is a group of inflammatory conditions, includes Crohn's disease and ulcerative colitis.

NPS MedicineWise reminds Australians to prevent overuse and misuse of antibiotics

Following from last night’s Catalyst episode, ‘Antibiotic Resistance’ on ABC TV examining Australia’s profligate use of antibiotics, NPS MedicineWise is reminding Australians to preserve the miracle of antibiotics by avoiding antibiotics when they’re not needed.

Scientists evaluate phage-based therapy to battle antibiotic-resistant bacterial superbug infections

Flinders University scientists are looking to bacteriophages – highly specific viruses - as the as the best way to attack antibiotic-resistant bacterial superbug infections.

Researchers develop insoles impregnated with silver nanoparticles to treat diabetic foot syndrome

Scientists from Tomsk Polytechnic University and National Autonomous Mexico University develop techniques to treat diabetic foot syndrome with special insoles with silver nano-particles. The techniques help to fight ulcers appearing on feet in diabetic patients, facilitates their healing and disinfection, reducing the risk of amputation.

Specific oral microbiome linked to pancreatic cancer risk

The presence of certain bacteria in the mouth may reveal increased risk for pancreatic cancer and enable earlier, more precise treatment. This is the main finding of a study led by researchers at NYU Langone Medical Center and its Laura and Isaac Perlmutter Cancer Center to be presented April 19 in New Orleans at the annual meeting of the American Association for Cancer Research.

Researchers develop new mathematical model to evaluate best treatment protocol to clear infection

Antibiotic resistance is one of the most challenging problems in modern medicine. A new study by Erida Gjini and Patricia H. Brito from the Instituto Gulbenkian de Ciência, provides a new mathematical model to evaluate the best treatment protocol to clear an infection, by taking into account the role of the host immune system.

Small piece of detoxified E. coli wall makes mice lose natural sweet tooth, study finds

Putting just a tiny piece of the wall of detoxified E. coli into their gut make mice lose their natural sweet tooth, researchers report.

Researchers focus on novel target to treat bacterial infection

Bacterial infection takes hold in the body when a pathogenic microorganism delivers toxins to healthy cells. One way bacteria accomplish this is by releasing vesicles, which act as tiny envelopes transporting toxins and other virulence factors to host cells. These toxins allow the bacteria to "make themselves at home" in cells.

Study describes precise mechanisms that enable TB bacteria to persist in the body

Bacteria that cause tuberculosis trick immune cells meant to destroy them into hiding and feeding them instead. This is the result of a study led by researchers from NYU Langone Medical Center and published online April 18 in Nature Immunology.

Sugar compounds provide nutrient support for growth of infant gut microbes

UC Davis researchers have shown that an enzyme produced by beneficial microbes in babies' intestines is able to harvest specific sugar compounds from human breast-milk and cow's milk. The discovery identifies those sugars -- rather than associated protein compounds -- as the key to nourishing those important, health-promoting microbes.

Researchers reveal how relatively unknown pathogen led to current Zika outbreak

An analysis comparing the individual differences between over 40 strains of Zika virus (30 isolated from humans, 10 from mosquitoes, and 1 from monkeys) has identified significant changes in both amino acid and nucleotide sequences during the past half-century.
