Australian doctors transplants first circulatory death human heart

Australian doctors transplants first circulatory death human heart

The St Vincent’s Hospital Heart Lung Transplant Unit has carried out the world’s first distant procurement of hearts donated after circulatory death (DCD). These hearts were subsequently resuscitated and then successfully transplanted into patients with end-stage heart failure Continue reading

Growing a blood vessel in a week

The technology for creating new tissues from stem cells has taken a giant leap forward. Three tablespoons of blood are all that is needed to grow a brand new blood vessel in just seven days. Continue reading

Without swift influx of substantial aid, Ebola epidemic in Africa poised to explode

Without swift influx of substantial aid, Ebola epidemic in Africa poised to explode

The Ebola virus disease epidemic already devastating swaths of West Africa will likely get far worse in the coming weeks and months unless international commitments are significantly and immediately increased, new research led by Yale researchers predicts. The findings are published online first in The Lancet Infectious Diseases . A team of seven scientists from Yale’s Schools of Public Health and Medicine and the Ministry of Health and Social Welfare in Liberia developed a mathematical transmission model of the viral disease and applied it to Liberia’s most populous county, Montserrado, an area already hard hit Continue reading

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

Competition keeps health-care costs low, U.S. researchers find

Medical practices in less competitive health-care markets charge more for services, according to a study conducted by researchers at the Stanford University School of Medicine and the National Bureau of Economic Research. The study, based on U.S 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
