Cleveland Clinic researchers investigating potential drug for treatment of Alzheimer's disease

Compound interacts with receptor in brain that plays role in neurodegenerative processes in Alzheimer's disease

2012-08-31

(Press-News.org) Friday, Aug. 31, 2012, Cleveland: A compound developed to treat neuropathic pain has shown potential as an innovative treatment for Alzheimer's disease, according to a study by researchers at Cleveland Clinic's Lerner Research Institute and Anesthesiology Institute.

"Cleveland Clinic dedicated two years of research into the examination of this compound and our findings show it could represent a novel therapeutic target in the treatment of Alzheimer's disease," said Mohamed Naguib, M.D., Professor of Anesthesiology, Cleveland Clinic Lerner College of Medicine. "Development of this compound as a potential drug for Alzheimer's would take many more years, but this is a promising finding worthy of further investigation."

In a study published online in the Neurobiology of Aging, the compound MDA7 induced beneficial immune responses that limited the development of Alzheimer's disease. Treatment with the compound restored cognition, memory and synaptic plasticity – a key neurological foundation of learning and memory – in an animal model.

Neuroinflammation is an important mechanism involved in the progression of Alzheimer's disease. The MDA7 compound has anti-inflammatory properties that act on the CB2 receptor – one of the two cannabinoid receptors in the body – but without the negative side effects normally seen with cannabinoid compounds.

Alzheimer's disease is an irreversible, fatal brain disease that slowly destroys memory and thinking skills. About 5 million people in the United States have Alzheimer's disease. With the aging of the population, and without successful treatment, there will be 16 million Americans and 106 million people worldwide with Alzheimer's by 2050, according to the 2011 Alzheimer's Disease Facts and Figures report from the Alzheimer's Association.

### Dr. Naguib is named on two patent applications on CB2 modulators submitted by the University of Texas MD Anderson Cancer Center.

International collaboration key to science and engineering globalization

2012-08-31

International collaboration is a key aspect of the globalization of science and engineering. A recent report and data evaluation released by the National Science Foundation (NSF) showed that one in six scientists and engineers in the United States reported working with individuals in other countries in a given week. International collaboration was more likely to occur among persons working in the for-profit sector, men, and those with higher levels of educational attainment. Individuals who earned postsecondary degrees both in the United States and abroad reported the highest ...

Customer service is an emotional experience

2012-08-31

Los Angeles, (August 31, 2012) You can probably recall a customer service experience that left you feeling good. A recent study has shown not only that positive emotion from sales staff is contagious to a customer, but that a satisfied customer also improves the salesperson's mood. This research is now available in Human Relations, published by SAGE. Sandra Kiffin-Petersen, and Geoffrey Soutar from University of Western Australia and Steven Murphy from Carlton University, Canada used a qualitative diary study with 276 sales employees to shed light on the sales experience ...

Intervention helps children with sickle cell disease complete MRI tests without sedation

2012-08-31

Sitting still is tough for children, which makes MRI scans a challenge. The scans require that patients remain motionless for extended periods. Findings from St. Jude Children's Research Hospital showed that a brief, targeted intervention dramatically increases the likelihood that children as young as 5 years old will be able to undergo testing without sedation. That is good news for children with sickle cell disease, who were the focus of this study. Patients with sickle cell disease often undergo brain and liver MRIs to check for complications related to their disease ...

Early activation of immune response could lead to better vaccines

2012-08-31

August 30, 2012 — (Bronx, NY) — Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a new "first response" mechanism that the immune system uses to respond to infection. The findings challenge the current understanding of immunity and could lead to new strategies for boosting effectiveness of all vaccines. The study, conducted in mice, published online today in the journal Immunity. Grégoire Lauvau, Ph.D.One way the immune system protects the body against microbes like bacteria and viruses is with memory CD8+ T cells, so named because ...

Information overload?

2012-08-31

EVANSTON, Ill. --- "Information overload" may be an exaggerated way to describe today's always-on media environment. Actually, very few Americans seem to feel bogged down or overwhelmed by the volume of news and information at their fingertips and on their screens, according to a new Northwestern University study. The study was published in the journal The Information Society. "Little research has focused on information overload and media consumption, yet it's a concept used in public discussions to describe today's 24/7 media environment," said Eszter Hargittai, an ...

Chemical exposure in the womb from household items may contribute to obesity

2012-08-31

Pregnant women who are highly exposed to common environmental chemicals - polyfluoroalkyl compounds (PFCs) - have babies that are smaller at birth and larger at 20 months of age, according to a study from Emory University's Rollins School of Public Health published online in the August 30 edition of Environmental Health Perspectives. PFCs are used in the production of fluoropolymers and are found widely in protective coatings of packaging products, clothes, furniture and non-stick cookware. They are persistent compounds found abundantly in the environment and human exposure ...

Leaders' emotional cues may predict acts of terror or political aggression

2012-08-31

Leaders often use rousing speeches to evoke powerful emotions, and those emotions may predict when a group will commit an act of violence or terrorism, according to new research published in the journal Behavioral Sciences of Terrorism and Political Aggression. Analysis of speeches delivered by government, activist and terrorist leaders found that leaders' expressions of anger, contempt and disgust spiked immediately before their group committed an act of violence. "When leaders express a combination of anger, contempt and disgust in their speeches, it seems to be instrumental ...

Walls of lunar crater may hold patchy ice, LRO radar finds

2012-08-31

Small patches of ice could make up at most five to ten percent of material in walls of Shackleton crater. Scientists using the Mini-RF radar on NASA's Lunar Reconnaissance Orbiter (LRO) have estimated the maximum amount of ice likely to be found inside a permanently shadowed lunar crater located near the moon's South Pole. As much as five to ten percent of material, by weight, could be patchy ice, according to the team of researchers led by Bradley Thomson at Boston University's Center for Remote Sensing, in Mass. "These terrific results from the Mini-RF team contribute ...
