Finally: Missing link between vitamin D, prostate cancer

Finally: Missing link between vitamin D, prostate cancer

A University of Colorado Cancer Center study recently published in the journal Prostate offers compelling evidence that inflammation may be the link between Vitamin D and prostate cancer. Specifically, the study shows that the gene GDF-15, known to be upregulated by Vitamin D, is notably absent in samples of human prostate cancer driven by inflammation Continue reading

Bipolar disorder discovery at the nano level

Bipolar disorder discovery at the nano level

A nano-sized discovery by Northwestern Medicine ® scientists helps explain how bipolar disorder affects the brain and could one day lead to new drug therapies to treat the mental illness. Scientists used a new super-resolution imaging method — the same method recognized with the 2014 Nobel Prize in chemistry — to peer deep into brain tissue from mice with bipolar-like behaviors.

Baby cries show evidence of cocaine exposure during pregnancy

Baby cries show evidence of cocaine exposure during pregnancy

A new study conducted by University of North Carolina School of Medicine researchers provides the first known evidence of how a similar acoustic characteristic in the cry sounds of human infants and rat pups may be used to detect the harmful effects of prenatal cocaine exposure on nervous system development. “These findings are important because studies of prenatal drug exposure in humans are always limited by not knowing if infant nervous system damage was due to the effects of a specific drug, such as cocaine, or the effects of other associated factors, such as maternal depression, poor prenatal care and other drug use, that are often linked with maternal drug use during pregnancy,” said Philip Sanford Zeskind, PhD, lead author of the study published October 22 in the journal PLOS ONE . “The discovery of the similar spectral characteristic in rat pup vocalizations will allow for translational analyses that can be used to detect the isolated effects of cocaine or similar drugs on brain limbic mechanisms common to humans, rodents and other mammals,” said Zeskind, a researcher at Levine Children’s Hospital at Carolinas Medical Center in Charlotte, North Carolina and a research professor of psychology and pediatrics at UNC Continue reading

Smoking interferes with neurocognitive recovery during abstinence from alcohol

Smoking interferes with neurocognitive recovery during abstinence from alcohol

Numerous studies have shown that individuals with an alcohol use disorder perform worse than those without one on multiple neurocognitive domains of function following detoxification from alcohol, although the level of impairment can vary widely among individuals. A new study of the degree of neurocognitive recovery in treatment-seeking alcohol dependent individuals (ALC) — with varied degrees of smoking status — during the first eight months of sustained abstinence from alcohol has found that smoking status influenced the rate and level of recovery Continue reading

How troubled marriage, depression history promote obesity

How troubled marriage, depression history promote obesity

The double-whammy of marital hostility and a history of depression can increase the risk for obesity in adults by altering how the body processes high-fat foods, according to new research. In the study, men and women with a history of depression whose arguments with spouses were especially heated showed several potential metabolic problems after eating a high-fat meal. They burned fewer calories and had higher levels of insulin and spikes of triglycerides — a form of fat in the blood — after eating a heavy meal when compared to participants without these risk factors.
