Onions could hold key to fighting antibiotic resistance

A type of onion could help the fight against antibiotic resistance in cases of tuberculosis, a UCL and Birkbeck-led study suggests.

Researchers believe the antibacterial properties extracted from the Persian shallot could increase the effects of existing antibiotic treatment. (more…)

Clever chemistry and a new class of antibiotics

A new class of molecules called acyldepsipeptides — ADEPs — may provide a new way to attack bacteria that have developed resistance to antibiotics. Researchers at Brown and MIT have discovered a way to increase the potency of ADEPs by up to 1,200 times. Their findings appear in the Journal of the American Chemical Society.

PROVIDENCE, R.I. [Brown University] — As concerns about bacterial resistance to antibiotics grow, researchers are racing to find new kinds of drugs to replace ones that are no longer effective. One promising new class of molecules called acyldepsipeptides — ADEPs — kills bacteria in a way that no marketed antibacterial drug does — by altering the pathway through which cells rid themselves of harmful proteins.

Living in Poor Area as Teen Could Increase Risk for Chlamydia in Young Adulthood

Study Points to Need for Interventions That Address Neighborhood Poverty

COLUMBUS, Ohio – Living in a poor neighborhood as an adolescent is linked to an increased risk of getting the sexually transmitted infection (STI) chlamydia in young adulthood, according to new research.

Ohio State University researchers analyzed data from a large national study that tracked youths over time. The analysis suggested that children who lived in poor neighborhoods during their teenage years had an almost 25 percent greater risk of having chlamydia in their early 20s – even if they themselves weren’t poor – than did teenagers living in wealthier settings.

Precautions for Tick-Borne Disease Extend “Beyond Lyme”

Save the tick that bites you: it may not be the one you think

This year’s mild winter and early spring were a bonanza for tick populations in the eastern United States. Reports of tick-borne disease rose fast.

While Lyme disease is the most common tick-borne disease in the Northeast and Upper Midwest, new research results emphasize that it is not the greatest cause for concern in most Southeastern states.

The findings are published today in a paper in the journal Zoonoses and Public Health. (more…)

Cycling May Negatively Affect Male Reproductive Health, UCLA Study Finds

A study by researchers at the UCLA School of Nursing has found that serious male cyclists may experience hormonal imbalances that could affect their reproductive health.

The study, “Reproductive Hormones and Interleukin-6 in Serious Leisure Male Athletes,” was recently published in the European Journal of Applied Physiology.

To date, an extensive amount of research has been done documenting the positive effects of long-term exercise on health. Yet while moderate exercise can lead to enhanced cardiovascular and metabolic function and reduced body fat, studies have shown that ultra-endurance levels of exercise can also adversely affect the neuroendocrine system and reproductive health.

Researchers Show Prebiotic Can Reduce Severity of Colitis

EAST LANSING, Mich. — Researchers at Michigan State University have shown a prebiotic may help the body’s own natural killer cells fight bacterial infection and reduce inflammation, greatly decreasing the risk of colon cancer.

Prebiotics are fiber supplements that serve as food for the trillions of tiny bacteria living in the gut. When taken, they can stimulate the growth of the “good” bacteria. The evolution of prebiotic supplements (as well as probiotics, which are actual bacteria ingested into the system) provide new therapeutic targets for researchers and physicians. (more…)

Research Shows Why One Bacterial Infection is So Deadly in Cystic Fibrosis

COLUMBUS, Ohio – Scientists have found why a certain type of bacteria, harmless in healthy people, is so deadly to patients with cystic fibrosis.

The bacterium, Burkholderia cenocepacia, causes a severe and persistent lung infection in patients with CF and is resistant to nearly all known antibiotics. Cystic fibrosis is a chronic disorder characterized by a buildup of mucus in the lungs and other parts of the body, and various types of lung infection are responsible for about 85 percent of deaths in these patients.

Computer Helps MSU Researchers Unravel Plants’ Secrets to Survival

EAST LANSING, Mich. — Recent research by Michigan State University scientists has shed more light on how plants are able to cope with extreme environments.

However, the name of one of the key contributors to the work, which is detailed in the online version of the Proceedings of the National Academy of Sciences, is not listed among the paper’s authors. That’s because it’s a cluster of computers. (more…)
