Addictive properties of drug abuse may hold key to an HIV cure

2012-09-21
(Press-News.org) TALLAHASSEE, Fla. — A Florida State University researcher is on a mission to explore the gene-controlling effects of addictive drugs in pursuit of new HIV treatments.

Working under the support of a $1.8 million grant from the National Institutes of Health (NIH), Florida State biologist Jonathan Dennis is studying a unique ability shared between a promising class of HIV treatments known as histone deacetylase inhibitors (HDIs) and psychostimulant drugs such as cocaine.

"Current HIV treatments do just that — they treat the disease by preventing the spread of HIV in the body, rather than eliminating the disease entirely," Dennis said. "I want to find out how to root out those dormant HIV cells that are evading the treatment, and I believe the gene-controlling functions shared by HDIs and psychostimulant drugs hold the key to helping us do that."

HDI and addictive drugs such as cocaine share the ability to control gene expression through changes in the chromatin structure within DNA. In the case of HDI treatment, the chromatin changes are used to wake up dormant HIV virus cells that are hiding in the body.

Dennis believes that addictive drugs do the same thing. Dennis' work will focus on identifying and understanding the overlapping gene changes that occur between these two types of substances, ultimately providing other researchers with the foundational information they need to turn HDI treatments into HIV cures.

How do we make moral judgments? Insights from Psychological Science

2012-09-21
New research published in Psychological Science, a journal of the Association for Psychological Science, provides intriguing insights into some of the factors that influence how we make moral judgments. Reappraising Our Emotions Allows Cooler Heads to Prevail We might like to think that our judgments are always well thought-out, but research suggests that our moral judgments are often based on intuition. Our emotions seem to drive our intuitions, giving us the gut feeling that something is 'right' or 'wrong.' In some cases, however, we seem to be able to override these ...

'Forest killer' plant study explores rapid environmental change factors

2012-09-21
TEMPE (Sept. 21, 2012) - It's called mile-a-minute weed or "forest killer." Mikania micrantha is an exotic, invasive species that spreads quickly, covering crops, smothering trees and rapidly altering the environment. Researchers at Arizona State University are spearheading a four-year research project that will explore what factors cause people and the environment to be vulnerable to rapid environmental change, such as an invasion by Mikania. Study findings likely will serve as a harbinger of the future as humans increasingly experience abrupt, extreme conditions associated ...

Study shows anaesthetic-related deaths reduced dramatically

2012-09-21
LONDON, ON – A team of researchers led by London's Dr. Daniel Bainbridge have compiled data from 87 studies worldwide that shows post-anaesthetic deaths have declined as much as 90 percent since before the 1970s. During the same period, the risk of dying from any cause within 48 hours of surgery has decreased by 88 percent. The study covered outcomes in both developed and developing countries, with the findings published in the current issue of the high-profile journal The Lancet. The study calls for use of evidence-based interventions to reduce the disparities between ...

Research identifies protein that regulates key 'fate' decision in cortical progenitor cells

2012-09-21
Cold Spring Harbor, NY – Researchers at Cold Spring Harbor Laboratory (CSHL) have solved an important piece of one of neuroscience's outstanding puzzles: how progenitor cells in the developing mammalian brain reproduce themselves while also giving birth to neurons that will populate the emerging cerebral cortex, the seat of cognition and executive function in the mature brain. CSHL Professor Linda Van Aelst, Ph.D., and colleagues set out to solve a particular mystery concerning radial glial cells, or RGCs, which are progenitors of pyramidal neurons, the most common type ...

Growing corn to treat rare disease

2012-09-21
The seeds of greenhouse-grown corn could hold the key to treating a rare, life-threatening childhood genetic disease, according to researchers from Simon Fraser University. SFU biologist Allison Kermode and her team have been carrying out multidisciplinary research toward developing enzyme therapeutics for lysosomal storage diseases - rare, but devastating childhood genetic diseases – for more than a decade. In the most severe forms of these inherited diseases, untreated patients die in early childhood because of progressive damage to all organs of the body. Currently, ...

LifeShield Builds Web Presence for Regional Authorized Dealers

2012-09-21
LifeShield Security authorized dealers throughout the country can now connect with consumers on a regional level through locally relevant websites that help to identify customers and prospects. Sites also offer special wireless home security deals to each region that are constantly changing. "Local dealers understand the security challenges particular to their own regions and therefore can be more successful at recruiting new customers," said Shannon Dominello, CMO, LifeShield. "Regional sites provide a legitimate local web presence for each dealer that ...

Fear can be erased from the brain

2012-09-21
Newly formed emotional memories can be erased from the human brain. This is shown by researchers from Uppsala University in a new study now being published by the academic journal Science. The findings may represent a breakthrough in research on memory and fear. Thomas Ågren, a doctoral candidate at the Department of Psychology under the supervision of Professors Mats Fredrikson and Tomas Furmark, has shown, that it is possible to erase newly formed emotional memories from the human brain. When a person learns something, a lasting long-term memory is created with the ...

Move to less impoverished neighborhoods boosts physical and mental health

2012-09-21
Moving from a high-poverty to lower-poverty neighborhood spurs long-term gains in the physical and mental health of low-income adults, as well as a substantial increase in their happiness, despite not improving economic self-sufficiency, according to a new study published in the Sept. 20 issue of Science by researchers at the University of Chicago and partners at other institutions. Although moving into less disadvantaged neighborhoods did not raise incomes for the families that moved, these families experienced important gains in well-being in other ways. Moving from ...

A mother’s nutrition--before pregnancy--may alter the function of her children’s genes

2012-09-21
Bethesda, MD—Everyone knows that what mom eats when pregnant makes a huge difference in the health of her child. Now, new research in mice suggests that what she ate before pregnancy might be important too. According to a new research report published online in The FASEB Journal, what a group of female mice ate—before pregnancy—chemically altered their DNA and these changes were passed to her offspring. These DNA alterations, called "epigenetic" changes, drastically affected the pups' metabolism of many essential fatty acids. These results could have a profound impact on ...

Treating disease by the numbers
2012-09-21
Mathematical modeling being tested by researchers at the School of Science at Indiana University-Purdue University Indianapolis (IUPUI) and the IU School of Medicine has the potential to impact the knowledge and treatment of several diseases that continue to challenge scientists across the world. The National Science Foundation recently recognized the work led by Drs. Giovanna Guidoboni, associate professor of mathematics in the School of Science, and Alon Harris, professor of ophthalmology and director of clinical research at the Eugene and Marilyn Glick Eye Institute, ...
