An antibiotic has been found to stimulate its own production. The findings, to be published in PNAS, could make it easier to scale up antibiotic production for commercialisation.

Scientists Dr Emma Sherwood and Professor Mervyn Bibb from the John Innes Centre were able to use their discovery of how the antibiotic is naturally produced to markedly increase the level of production.

"We have shown for the first time that an antibiotic with clinical potential can act as signalling molecule to trigger its own synthesis," said Professor Bibb.

A new drug called pyrvinium pamoate inhibits aggressive forms of prostate cancer that are resistant to standard drugs, according to a study conducted in an animal model. The results will be presented Monday at The Endocrine Society's 95th Annual Meeting in San Francisco.

"Our novel prostate cancer drug works by a unique mechanism of action," said study lead author Jeremy Jones, PhD, assistant professor of molecular pharmacology at City of Hope, Beckman Research Institute, in Duarte, CA. "Thus, it has the potential to treat cancers resistant to currently approved therapies."

CHICAGO --- Young women who have cancer treatment often lose their fertility because chemotherapy and radiation can damage or kill their immature ovarian eggs, called oocytes. Now, Northwestern Medicine® scientists have found the molecular pathway that can prevent the death of immature ovarian eggs due to chemotherapy, potentially preserving fertility and endocrine function.

Scientists achieved this in female mice by adding a currently approved chemotherapy drug, imatinib mesylate, to another chemotherapy drug cisplatin.

A new genetic test accurately and consistently diagnoses benign growths, or nodules, on the thyroid gland, according to a study from Chile. The results will be presented Saturday at The Endocrine Society's 95th Annual Meeting in San Francisco.

"We have developed a 'gene signature' that effectively identifies benign thyroid nodules," said Hernan Gonzalez, MD, PhD, associate professor at the Pontifical Catholic University of Chile in Santiago. "This test is potentially useful to identify patients who do not require surgery."

During labor and delivery, infants preferentially secrete a different stress hormone than their mothers do, according to a new clinical study. The results will be presented Saturday at The Endocrine Society's 95th Annual Meeting in San Francisco and published in the open access journal, PLoS One.

SAN FRANCISCO-- A supplemental beverage used to treat muscle-wasting may help boost muscle mass among the elderly, according to a new study. The results were presented today at The Endocrine Society's 95th Annual Meeting in San Francisco.

SAN FRANCISCO-- A type of drug normally used to treat heart failure and high blood pressure helped prevent weight gain and other complications related to a high-fat diet in an animal study. The results were presented today at The Endocrine Society's 95th Annual Meeting in San Francisco.

SAN FRANCISCO-- Overweight and obese men secrete greater amounts of stress hormones after eating, which may make them more susceptible to disease, a new observational study finds. The results will be presented Saturday at The Endocrine Society's 95th Annual Meeting in San Francisco.

Although body weight is largely determined by lifestyle factors, increasingly research is revealing that genetics also play an important role in determining an individual's susceptibility to obesity.

Adenoid cystic carcinoma (ACC) is a slow-growing and often fatal malignancy that can occur at multiple organ site, but is most frequently found in the salivary glands. The primary treatment is surgical removal; however, the majority of patients develop metastatic disease. In this issue of the Journal of Clinical Investigation, researchers led by Andrew Futreal at the Wellcome Trust Sanger Institute in Cambridge, MA, performed a type of genetic sequencing known as whole exome sequencing of 24 ACC cases.

Eating behaviours of preschoolers may be associated with risk of cardiovascular disease in later life, suggests a study published in CMAJ (Canadian Medical Association Journal).

Mobile health technology has substantial potential for improving access to health care in the developing world and in remote regions of developed countries, states an article in CMAJ (Canadian Medical Association Journal).

Early exposure to BPA (bisphenol A) – an additive commonly found in plastic water bottles and soup can liners – causes an increased cancer risk in an animal model of human prostate cancer, according to University of Illinois at Chicago researcher Gail Prins.Prins presented her findings at the ENDO 2013 meeting in San Francisco June 17.

Ulsan, S. Korea, June 17, 2013 - Researchers from Ulsan National Institute of Science and Technology (UNIST), S. Korea, developed a novel, simple method to synthesize hierarchically nanoporous frameworks of nanocrystalline metal oxides such as magnesia and ceria by the thermal conversion of well-designed metal-organic frameworks (MOFs).

The novel material developed by the UNIST research team has exceptionally high CO2 adsorption capacity which could pave the way to save the Earth from CO2 pollution.

SAN FRANCISCO—- Testosterone therapy is associated with decreased pain perception in men with low testosterone levels related to opioid (narcotic) pain relievers (analgesics), a new study finds. The results were presented Monday at The Endocrine Society's 95th Annual Meeting in San Francisco.
