Human stem cell-derived neuron transplants reduce seizures in mice

Thu, 06/11/2014 - 6:22pm
Scientists have new evidence that stem cell transplantation could be a worthwhile strategy to help epileptics who do not respond to anti-seizure drugs. Most epileptic patients can be treated with anti-seizure drugs, which contain molecules that can inhibit electrical symptoms, similar to the normal function of interneurons. But about one-third do not benefit from existing medication.

Body weight heavily influenced by gut microbes: Genes shape body weight by affecting gut microbes

Thu, 06/11/2014 - 6:22pm
Our genetic makeup influences whether we are fat or thin by shaping which types of microbes thrive in our body, according to a new study. Scientists identified a specific, little known bacterial family that is highly heritable and more common in individuals with low body weight. This microbe also protected against weight gain when transplanted into mice. The results could pave the way for personalized probiotic therapies that are optimized to reduce the risk of obesity-related diseases based on an individual's genetic make-up.

Human blood stem cells genetically 'edited'

Thu, 06/11/2014 - 6:22pm
Researchers, for the first time, have used a relatively new gene-editing technique to create what could prove to be an effective technique for blocking HIV from invading and destroying patients' immune systems.

A cause of age-related inflammation found

Thu, 06/11/2014 - 6:22pm
As animals age, their immune systems gradually deteriorate, a process called immunosenescence. It is associated with systemic inflammation and chronic inflammatory disorders, as well as with many cancers. The causes underlying this age-associated inflammation, and how it leads to diseases, are poorly understood. New work sheds light on one protein's involvement in suppressing immune responses in aging fruit flies.

New knowledge about human brain's plasticity

Thu, 06/11/2014 - 6:18pm
The brain's plasticity and its adaptability to new situations do not function the way researchers previously thought, according to a new study. Earlier theories are based on laboratory animals, but now researchers have studied the human brain, and reached some new conclusions.

Images of a nearly invisible mouse

Thu, 06/11/2014 - 6:18pm
A method that combines tissue decolorization and light-sheet fluorescent microscopy has been developed to take extremely detailed images of the interior of individual organs and even entire organisms. The work opens new possibilities for understanding the way life works -- the ultimate dream of systems biology -- by allowing scientists to make tissues and whole organisms transparent and then image them at extremely precise, single-cell resolution.

First-in-class nasal spray demonstrates promise for migraine pain relief

Thu, 06/11/2014 - 6:18pm
Researchers are developing a novel prochlorperazine nasal spray formulation as a potential new treatment for migraines. Of the 100 million people that experience headaches in the United States, 37 million of them suffer from migraines.

Antibiotics: On-the-spot tests reduce unnecessary prescriptions

Thu, 06/11/2014 - 1:35am
Fast, on-the-spot tests for bacterial infections may help to reduce excessive antibiotic use. A systematic review found that when doctors tested for the presence of bacterial infections they prescribed fewer antibiotics.

CT lung screening appears cost-effective

Thu, 06/11/2014 - 1:35am
In 2010 the National Lung Screening Trial showed that screening for cancer with low-dose CT scans could reduce mortality by 20 percent compared to using chest X-rays. But is it cost-effective? A new study's calculations reveal that it is, but that depends on assuming many answers to questions that remain open.

Further evidence of potential for new anti-cancer drug

Thu, 06/11/2014 - 1:34am
Scientists have shown that a new drug inhibits the growth of tumors in the lab and that its effectiveness is improved by combining it with radiotherapy – suggesting a new approach that could be used in the clinic, they say.

'Aging well' must be a global priority, experts say

Thu, 06/11/2014 - 1:34am
Worldwide, life expectancy of older people continues to rise. By 2020, for the first time in history, the number of people aged 60 years and older will outnumber children younger than 5 years. By 2050, the world’s population aged 60 years and older is expected to total 2 billion, up from 841 million today. 80% of these older people will be living in low-income and middle-income countries. However, although people are living longer, they are not necessarily healthier than before, experts report.

Mosquitofish genitalia change rapidly due to human impacts

Wed, 05/11/2014 - 9:52pm
Human environmental changes can markedly -- and rapidly -- affect fish shape, specifically the shape of mosquitofish genitalia in the Bahamas. These findings indicate that sometimes the impacts of human activities on the traits of organisms can be predictable, suggesting that management, restoration and conservation efforts could be useful.
