Scientists develop revolutionary approach for reconstructing intricate bone tissue

Every year nearly 6.2 million bone fractures occur in the United States as a result of trauma and disease. Current standards for bone repair can lead to rapid bone fusion but with limited mechanical strength often due to the lack of cortical bone tissue which is difficult to harvest without pain and severe morbidity. Funded by the National Science Foundation, Dr. Hongjun Wang, a professor in the Department of Chemistry, Chemical Biology and Biomedical Engineering at Stevens Institute of Technology and his collaborators have developed a revolutionary "bottom-up" approach for reconstructing intricate bone tissue with the potential to form hierarchical cortical bone.

Scientists analyze new technique to quickly identify particular asthma subtypes

For many people afflicted by asthma, treatment can be a frustrating and time-consuming experience. After their initial diagnosis, asthmatics find themselves caught in a trial and error process that can last for months, as doctors gradually escalate their medications to treat their condition effectively with minimal side effects. And until the right medicine and dosage are found, patients continue to suffer attacks that strike without warning and can leave them struggling for breath for hours or even days.

Certain proteins, genes play key role in regenerating lost body parts: Research

Another option may be on the horizon for patients who lose limbs due to war, accident, or disease. Instead of using artificial legs or arms, patients actually may regrow their own missing limbs. An article in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine, focuses on research efforts to turn the long-standing dream of human limb regeneration into reality.

Injecting PAP may reduce chronic pain: Research

A study published in the Aug. 4, 2010 issue of the Journal of Neuroscience introduces an enzyme that could pack a big punch in the battle against chronic pain. Its name is prostatic acid phosphatase or PAP for short. According to researchers at the University of North Carolina at Chapel Hill, PAP blocks pain in animal models by siphoning off a molecule called PIP2—a critical component of the chemical cascade behind chronic pain.

Foldit players to focus on designing novel proteins

Computer scientists and biochemists at the University of Washington two years ago launched an ambitious project harnessing the brainpower of computer gamers to solve medical problems. The game, Foldit, turns one of the hardest problems in molecular biology into a game a bit reminiscent of Tetris. Thousands of people have now played a game that asks them to fold a protein rather than stack colored blocks or rescue a princess.

Scientists suggest home genetic tests may cause unnecessary stress

In the age of the Internet, where cybercondriacs are just a mouse click away from a diagnosis, do-it-yourself home genetics test may seem like the next logical step in managing health. But these tests, which are relatively new and available online, are often not comprehensive and may cause unnecessary stress, warns Suzanne Mahon, DNSc., a clinical professor of hematology and oncology at Saint Louis University.

Scientists develop new chip to increase forensic DNA testing speed

A newly developed test could make checking DNA from people arrested for crimes with DNA samples from crime scenes stored in forensic databases almost as easy as matching fingerprints. With the test, police could check on whether a person's DNA matches that found at past crime scenes while suspects are still being processed and before a decision on whether to release them on bail. A report on the fast forensic test appears in the ACS' Analytical Chemistry, a semi-monthly journal.

Long-term exposure to valproate leads to bone loss: Study

Scientists are reporting a possible explanation for the bone loss that may occur following long-term use of a medicine widely used to treat epilepsy, bipolar disorder, and other conditions. The drug, valproate, appears to reduce the formation of two key proteins important for bone strength, they said. Their study, which offers a solution to a long-standing mystery, appears in ACS' monthly Journal of Proteome Research.

SORT1 pathway holds promise as new target for therapeutic intervention for LDL cholesterol reduction

The true power of genomic research lies in its ability to help scientists understand biological processes, particularly those that - when altered - can lead to disease. This power is demonstrated dramatically in a pair of papers published today in the journal Nature. In the first, a global team of researchers describes 95 different variations across the genome that contribute in different degrees to alterations in blood cholesterol and triglyceride levels in multiple human populations. In the second report, close examination of just one of these common variants not only reveals the involvement of an unexpected genetic pathway in lipid metabolism but also provides a blueprint for using genomic findings to unravel biological connections between lipid levels and coronary heart disease.

Certain human leukemias can be treated by targeting stem-cell microRNAs: Research

Hematopoietic stem cells provide the body with a constant supply of blood cells, including the red blood cells that deliver oxygen and the white blood cells that make up the immune system. Hematopoietic-or blood-stem cells must also make more copies of themselves to ensure that they are present in adequate numbers to provide blood throughout a person's lifetime, which means they need to strike a delicate balance between self-renewal and development into mature blood-cell lineages. Perturb that balance, and the result can be diseases such as leukemia and anemia.
