Research findings may open door to new therapeutic strategies for serious health problems

Drugs that target the way cells convert nutrients into energy could offer new approaches to treating a range of conditions including heart attack and stroke. Using a new way to screen for potential drugs, a team led by Massachusetts General Hospital (MGH) researchers has identified several FDA-approved agents, including an over-the-counter anti-nausea drug, that can shift cellular energy metabolism processes in animals.

Potential cancer-killing compounds synthesized

Yale University scientists have streamlined the process for synthesizing a family of compounds with the potential to kill cancer and other diseased cells, and have found that they represent a unique category of anti-cancer agents. Their discovery appears in this week's online edition of the Journal of the American Chemical Society.

Muscle-preserving therapy development may help young men keep muscle shirts a bit longer

Hey guys, remember the muscle shirts we wore in our teens and 20s? After the age of 40 that meager part of our wardrobes usually is obsolete. Yes, at the big 4-0 we begin to lose muscle, and by age 80 up to a third of it may be gone. It's an inevitable process of aging called sarcopenia.

Scientists identify bacterial protein VpsT as master regulator in Vibrio

Finding a biological mechanism much like an online social network, scientists have identified the bacterial protein VpsT as the master regulator in Vibrio, the cause of cholera and other enteric diseases. This discovery, now published in the journal Science, provides a major tool to combat enteric disease.

Fast method for producing bone and cartilage tissue using body's own cells

Injuries to joints and cartilage can have serious consequences, including osteoarthritis. Cartilage degeneration in joints is a widespread disease in Germany and worldwide. Prof. Dr. Prasad Shastri is an expert in tissue engineering (TE), tissue construction and tissue cultivation using the body's own cells. He is Professor of Biofunctional Macromolecular Chemistry at the Centre for Biological Signalling Studies (BIOSS), a Cluster of Excellence at the University of Freiburg, where he has been researching for the last year.

Negative life experiences can harm developing capacity for love

Do you make the same mistakes in love over and over again? For example, do you always seem to pick the wrong partner or always experience the same negative romantic outcome? If so, you need to understand your developmental history of love and break the pattern, according to Dr. Mark Beitel, a licensed clinical psychologist and psychotherapist at Greenwich Hospital's Center for Integrative Medicine in Cos Cob, CT.

Researchers identify defective signaling pathway that contributes to the severity of cystic fibrosis

In a study that could lead to new therapeutic targets for patients with the cystic fibrosis, a research team from the University of California, San Diego School of Medicine has identified a defective signaling pathway that contributes to disease severity.

SRC-3 gene sends signal to cell membrane to promote cell motility

The master gene called SRC-3 (steroid receptor coactivator 3) not only enhances estrogen-dependent growth of cancer cells by activating and encouraging the transcription of a genetic message into a protein, it also sends a signal to the cell membrane to promote cell motility or movement - a key element of cancer spread or metastasis, said Baylor College of Medicine (www.bcm.edu) researchers and collaborators in a report that appears in the current issue of the journal Molecular Cell.

Researchers discover Dab2 protein that switches on EMT process

Reporting in Nature Cell Biology, researchers describe the discovery of a specific protein called disabled-2 (Dab2) that switches on the process that releases cancer cells from the original tumor and allows the cells to spread and develop into new tumors in other parts of the body.

Proteins found in intestines can recognize and kill bacteria that have human blood type molecules

A set of proteins found in our intestines can recognize and kill bacteria that have human blood type molecules on their surfaces, scientists at Emory University School of Medicine have discovered.

Idera Pharmaceuticals presents TLR antagonist preclinical hyperlipidemia data at Keystone Symposia conference

Idera Pharmaceuticals, Inc. presented data on the evaluation of a Toll-like receptor (TLR) antagonist in a preclinical hyperlipidemia model today at the Keystone Symposia conference “Advances in Molecular Mechanisms of Atherosclerosis” being held in Banff, Alberta, Canada. Idera’s proprietary TLR antagonists have dual activity for both TLR7 and TLR9, and present a potentially innovative approach for the treatment of certain autoimmune diseases.

Researchers describe the structure of ToxT that controls virulent nature of Vibrio cholerae

In a new study, Dartmouth researchers describe the structure of a protein called ToxT that controls the virulent nature of Vibrio cholerae, the bacteria that causes cholera. Buried within ToxT, the researchers were surprised to find a fatty acid that appears to inhibit ToxT, which prevents the bacteria from causing cholera.

Patients receiving female-donor plasma did better than patients receiving male-donor plasma: Study

Three years after the U.S. blood banking industry issued recommendations that discourage transfusing plasma from female donors because of a potential antibody reaction, Duke University Medical Center researchers discovered that female plasma actually may have advantages.

Histone modifications associated with pancreatic cancer development and progression

Specific chemical modifications to proteins called histones, which are found in the nucleus of cells and act as spools around which DNA is wound, can be used to predict prognosis and response to treatment in subsets patients with pancreatic cancer, a study by researchers at UCLA's Jonsson Comprehensive Cancer Center has found.

Gold nanoparticles for cancer treatment

World Gold Council (WGC) has today published 'Gold for Good: Gold and nanotechnology in the age of innovation', a research paper detailing new scientific and technological innovations using gold. The report, which was produced in conjunction with Cientifica Ltd, the world's leading source of global business and investor intelligence about nanotechnologies, demonstrates how gold nanoparticles offer the potential to overcome many of the serious issues facing mankind over the coming decades.

Humans are economical walkers, but not efficient runners

Humans, other great apes and bears are among the few animals that step first on the heel when walking, and then roll onto the ball of the foot and toes. Now, a University of Utah study shows the advantage: Compared with heel-first walking, it takes 53 percent more energy to walk on the balls of your feet, and 83 percent more energy to walk on your toes.

Treating bacteria with insufficient levels of antibiotics leads to multidrug resistance in 'superbugs'

For years, doctors have warned patients to finish their antibiotic prescriptions or risk a renewed infection by a "superbug" that can mount a more powerful defense against the same drug. But a new study by Boston University biomedical engineers indicates that treating bacteria with levels of antibiotics insufficient to kill them produces germs that are cross-resistant to a wide range of antibiotics.
