Role reversal: Linking a reproductive pathway to obesity

2014-06-18
(Press-News.org) People and mice with mutations in a specific signaling pathway, known as kisspeptin, suffer reproductive effects such as delayed puberty and infertility. Research of this pathway has focused on its role in reproduction, but a June 17 study in the Journal of Clinical Investigation looked at its effects on metabolism. Alexander Kauffman and colleagues at the University of California San Diego found that lack of the kisspeptin pathway in female mice promotes excess weight gain. Mice became overweight as the result of a reduced metabolism and decreased energy, but not as a result of increased food consumption. In her Commentary "Fatness and fertility: which direction?", Stephanie Seminara of Massachusetts General Hospital commends the identification of a link between kisspeptin and metabolism. The results of this study have potential to translate into approaches to treat human obesity.

A new twist on neuro disease: Discovery could aid people with dystonia, Parkinson's and more

2014-06-18
ANN ARBOR, Mich. -- Twist and hold your neck to the left. Now down, and over to the right, until it hurts. Now imagine your neck – or arms or legs – randomly doing that on their own, without you controlling it. That's a taste of what children and adults with a neurological condition called dystonia live with every day – uncontrollable twisting and stiffening of neck and limb muscles. The mystery of why this happens, and what can prevent or treat it, has long puzzled doctors, who have struggled to help their suffering dystonia patients. Now, new re-search from a University ...

Stress hormone linked to short-term memory loss as we age

2014-06-18
A new study at the University of Iowa reports a potential link between stress hormones and short-term memory loss in older adults. The study, published in the Journal of Neuroscience, reveals that having high levels of cortisol—a natural hormone in our body whose levels surge when we are stressed—can lead to memory lapses as we age. Short-term increases in cortisol are critical for survival. They promote coping and help us respond to life's challenges by making us more alert and able to think on our feet. But abnormally high or prolonged spikes in cortisol—like what ...

Kidney problems may prevent heart attack patients from receiving life-saving care

2014-06-18
Heart attack patients with kidney problems may not be getting the full treatment they need, according to a new study led by King's College London. The study found that patients admitted to hospital with chest pains and poorly functioning kidneys are less likely to be given an angiogram and early invasive treatment, which might increase their chance of surviving a heart attack. People admitted to hospital with a suspected heart attack are normally offered early angiography or X-ray of their heart – a procedure recommended in UK, European and US healthcare guidelines regardless ...

What amino acids in shells can tell us about Bronze Age people

2014-06-18
A new study by scientists at the University of York has shed new light on the use of mollusc shells as personal adornments by Bronze Age people. The research team used amino acid racemisation analysis (a technique used previously mainly for dating artefacts), light microscopy, scanning electron microscopy and Raman spectroscopy, to identify the raw materials used to make beads in a complex necklace discovered at an Early Bronze Age burial site at Great Cornard in Suffolk, UK. They discovered that Bronze Age craftspeople used species like dog whelk and tusk shells, both ...

Brain imaging shows enhanced executive brain function in people with musical training

Brain imaging shows enhanced executive brain function in people with musical training
2014-06-18
BOSTON (June 17, 2014)—A controlled study using functional MRI brain imaging reveals a possible biological link between early musical training and improved executive functioning in both children and adults, report researchers at Boston Children's Hospital. The study, appearing online June 17 in the journal PLOS ONE, uses functional MRI of brain areas associated with executive function, adjusting for socioeconomic factors. Executive functions are the high-level cognitive processes that enable people to quickly process and retain information, regulate their behaviors, make ...

Stress hormone elevation is associated with working memory deficits in aging

2014-06-18
Washington, DC — A new study published in the June 18 issue of The Journal of Neuroscience adds to a body of evidence suggesting stress may accelerate cognitive decline later in life. The study found that aged rats with high levels of the stress hormone corticosterone showed structural changes in the brain and short-term memory deficits. While most people will experience some cognitive decline as they get older, the extent of these changes and how rapidly they progress varies greatly from one person to the next. Scientists are interested in understanding the factors ...

Penn Medicine study shows 'clot-busting' drugs reduce deaths from pulmonary embolism by nearly half

Penn Medicine study shows clot-busting drugs reduce deaths from pulmonary embolism by nearly half
2014-06-17
PHILADELPHIA - Bringing clarity to a decades-long debate, a national team of researchers led by experts from the Perelman School of Medicine at the University of Pennsylvania has found that adding clot-busting medications known as thrombolytics to conventional approaches when treating sudden-onset pulmonary embolism patients is associated with 47 percent fewer deaths than using standard intravenous or under-the-skin anticoagulant medications alone. A pulmonary embolism is a blockage of one or more arteries in the lungs, primarily because of blood clots that travel there ...

Analysis finds mixed results for use of thrombolytic therapy for blood clot in lungs

2014-06-17
In an analysis that included data from 16 trials performed over the last 45 years, among patients with pulmonary embolism, receipt of therapy to dissolve the blood clot (thrombolysis) was associated with lower rates of death, but increased risks of major bleeding and intracranial hemorrhage, according to a study in the June 18 issue of JAMA. The authors note that these findings may not apply to patients with low-risk pulmonary embolism. Pulmonary embolism (PE; a blockage of the main artery of the lung or one of its branches) is an important cause of illness and death, ...

Survey suggests that self-reported health of young adults has improved

2014-06-17
Findings of a large survey indicate that since 2010, when young adults could be covered under their parents' health insurance plans until age 26, self-reported health among this group has improved, along with a decrease in out-of-pocket health care expenditures, according to a study in the June 18 issue of JAMA. Beginning September 23, 2010, the Affordable Care Act allowed young adults to be covered under their parents' plans until 26 years of age. This dependent coverage provision increased insurance coverage and access among young adults. However, little is known about ...

TNF inhibitors for treatment of bowel disease not linked with increased risk of cancer

2014-06-17
In a study that included more than 56,000 patients with inflammatory bowel disease, use of a popular class of medications known as tumor necrosis factor alpha antagonists was not associated with an increased risk of cancer over a median follow-up of 3.7 years, although an increased risk of malignancy in the long term, or with increasing number of doses, cannot be excluded, according to a study in the June 18 issue of JAMA. Tumor necrosis factor α (TNF-α) antagonists are drugs that have been shown to be beneficial in reducing the inflammation in inflammatory ...
