Enzyme ‘wrench’ could be key to stronger, more effective antibiotics

Enzyme ‘wrench’ could be key to stronger, more effective antibiotics

Builders and factory workers know that getting a job done right requires precision and specialized tools. The same is true when you’re building antibiotic compounds at the molecular level. New findings from North Carolina State University may turn an enzyme that acts as a specialized “wrench” in antibiotic assembly into a set of wrenches that will allow for greater customization.

Researchers search for earliest roots of psychiatric disorders

Researchers search for earliest roots of psychiatric disorders

Newborns whose mothers were exposed during pregnancy to any one of a variety of environmental stressors — such as trauma, illness, and alcohol or drug abuse — become susceptible to various psychiatric disorders that frequently arise later in life. However, it has been unclear how these stressors affect the cells of the developing brain prenatally and give rise to conditions such as schizophrenia, post-traumatic stress disorder, and some forms of autism and bipolar disorders Continue reading

Bad penny: Cancer’s thirst for copper can be targeted

Bad penny: Cancer’s thirst for copper can be targeted

Drugs used to block copper absorption for a rare genetic condition may find an additional use as a treatment for certain types of cancer, researchers at Duke Medicine report. The researchers found that cancers with a mutation in the BRAF gene require copper to promote tumor growth. These tumors include melanoma, the most dangerous form of skin cancer that kills an estimated 10,000 people in the United States a year, according to the National Cancer Institute. Continue reading

Promising agents burst through ‘superbug’ defenses to fight antibiotic resistance

Promising agents burst through ‘superbug’ defenses to fight antibiotic resistance

In the fight against “superbugs,” scientists have discovered a class of agents that can make some of the most notorious strains vulnerable to the same antibiotics that they once handily shrugged off. The report on the promising agents called metallopolymers appears in the Journal of the American Chemical Society . Chuanbing Tang and colleagues note that the antibiotic-resistant bacteria known as MRSA (methicillin-resistant Staphylococcus aureus ) is responsible for a significant fraction of the infections that patients acquire in hospitals Continue reading

Proprioceptive feedback helps rehab patients learning to operate robotic prosthetic

Proprioceptive feedback helps rehab patients learning to operate robotic prosthetic

The unconscious process by which human beings perceive the position of their body parts — known as proprioception — is a critical element of the body’s motor control system. Proprioceptive feedback plays a key role in rehabilitation following a brain injury. Continue reading

Potential therapeutic target for deadly brain cancer

Potential therapeutic target for deadly brain cancer

Researchers from the Geisel School of Medicine at Dartmouth will present a scientific poster on Tuesday, April 8, 2014 at the American Association of Cancer Researchers Annual Meeting in San Diego, CA. The research identifies a potential characteristic for predicting outcome in a deadly form of brain cancer known as glioblastoma multiforme. Existing therapies based on genetic information have failed to effectively treat glioblastomas Continue reading

Hormone therapy linked to lower non-Hodgkin lymphoma risk

Hormone therapy linked to lower non-Hodgkin lymphoma risk

Hormone therapy, which is prescribed to women for relief of menopausal symptoms such hot flashes, night sweats and vaginal dryness, has recently seen a decline in popularity (and use) due to its link to an increased risk of breast and endometrial cancer. Continue reading

Hormone therapy linked to lower non-Hodgkin lymphoma risk

Hormone therapy, which is prescribed to women for relief of menopausal symptoms such hot flashes, night sweats and vaginal dryness, has recently seen a decline in popularity (and use) due to its link to an increased risk of breast and endometrial cancer. But City of Hope researchers have found that menopausal hormone therapy may actually lower the risk of B-cell non-Hodgkin lymphoma. Sophia Wang, Ph.D., associate professor at City of Hope’s Division of Cancer Etiology and first author of this study, will present the findings at the American Association for Cancer Research (AACR) annual meeting on Monday, April 7.

Genes increase the stress of social disadvantage for some children

Genes increase the stress of social disadvantage for some children

Genes amplify the stress of harsh environments for some children, and magnify the advantage of supportive environments for other children, according to a study that’s one of the first to document how genes interacting with social environments affect biomarkers of stress. Continue reading
