Potential new therapeutic targets for rejuvenating the aged immune system

In the November 15th issue of G&D, Dr. Kenneth Dorshkind and colleagues at the David Geffen School of Medicine (UCLA) have identified two genes - p16(Ink4a) and Arf - that sensitize lymphoid progenitor cells to the effects of aging, and confer resistance to leukemogenesis.

Gender found to be play important role as a prognostic factor in people diagnosed with lung cancer

Even though some combinations of gender, race and/or marital status can factor into the overall survival of nonoperative non-small cell lung cancer patients, gender is the most significant factor impacting overall survival, according to a study presented at the 2008 Chicago Multidisciplinary Symposium in Thoracic Oncology, sponsored by ASTRO, ASCO, IASLC and the University of Chicago.

Difluoromethylornithine may affect Barrett's esophagus

"While there was a suggestion that difluoromethylornithine (DFMO) may influence the extent of Barrett's dysplasia, this finding is very preliminary and further study of this agent in a larger number of patients is needed," said Frank A. Sinicrope, M.D., professor of medicine and oncology at the Mayo Clinic, Rochester, MN.

Cigarette smoke may reshape the left ventricle

Prolonged exposure to cigarette smoke can increase levels of the stress hormone norepinephrine and enzymes in the heart that have the potential to reshape the left ventricle, according to new research at the University of Illinois at Chicago.

Traditional chemotherapy agents with targeted therapies improves survival in advance-stage lung cancer

The combination of traditional chemotherapy agents with targeted therapies called monoclonal antibodies showed no safety concerns and improved survival in patients with advanced non-small cell lung cancer according to a study presented at the 2008 Chicago Multidisciplinary Symposium in Thoracic Oncology, sponsored by ASTRO, ASCO, IASLC and the University of Chicago.

Advanced lung cancer patients see improved, progression-free survival

Patients with advanced non-small cell lung cancer whose disease has progressed following chemotherapy have a higher rate of tumor shrinkage and a longer interval before cancer progression when bevacizumab is added to standard second-line erlotinib therapy, according to a study presented at the 2008 Chicago Multidisciplinary Symposium in Thoracic Oncology, sponsored by ASTRO, ASCO, IASLC and the University of Chicago.

Breakthrough in cell-type analysis offers new ways to study development and disease

Like skilled assassins, many diseases seem to know exactly what types of cells to attack. While decimating one cadre of cells, diseases will inexplicably spare a seemingly identical group of neighbors. What makes cells vulnerable or not depends largely on the kinds and amounts of proteins they produce - their 'translational profile,' in the lingo of molecular biology. For this reason, scientists have struggled to parse the subtle molecular differences among the hundreds of specialized cell types that are tangled together in tissues like the brain.

Plants shown to accumulate nanoparticles in tissues

Researchers at the University of Delaware have provided what is believed to be the first experimental evidence that plants can take up nanoparticles and accumulate them in their tissues.

Research shows why some heart failure treatments fail

Do the biological underpinnings of heart failure share more in common with cancerous tumors than other cardiovascular diseases?

Intraspinal implant of mesenchymal stem cells may not heal the demyelinated spinal cord

Multiple sclerosis is a disease caused by the loss of the myelinated sheath surrounding the nerve fibers of the spinal cord.

Discovery of essential mechanism for maintenance of myelin's structure

In a new study, researchers at the Montreal Neurological Institute (MNI), McGill University, and the University of Montreal have discovered an essential mechanism for the maintenance of the normal structure of myelin, the protective covering that insulates and supports nerve cells (neurons).

Isoflurane induces Alzheimer's-associated changes in mouse brains

For the first time researchers have shown that a commonly used anesthetic can produce changes associated with Alzheimer's disease in the brains of living mammals, confirming previous laboratory studies.
