Scientists uncover critical genetic mutation in patients with MDS

Scientists have uncovered a critical genetic mutation in some patients with myelodysplastic syndromes - a group of blood cancers that can progress to a fatal form of leukemia.

Lab results change in consistent ways during the course of Kawasaki disease

Children with Kawasaki disease show a pattern of changing laboratory test results as the disease runs its course, according to a study in the December issue of The Pediatric Infectious Disease Journal.

New drug candidate may halt mental decline of Alzheimer's

A new drug candidate may be the first capable of halting the devastating mental decline of Alzheimer's disease, based on the findings of a study published today in PLoS one.

Cereblon protein now holds hope in fight against multiple myeloma

Research on the same protein that was a primary mediator of the birth defects caused by thalidomide now holds hope in the battle against multiple myeloma, say Mayo Clinic researchers who presented results of several clinical trials at the 53nd annual meeting of the American Society of Hematology Dec. 10-13 in San Diego.

Antioxidant can delay onset of all indicators of Alzheimer's

When you cut an apple and leave it out, it turns brown. Squeeze the apple with lemon juice, an antioxidant, and the process slows down. Simply put, that same "browning" process-known as oxidative stress-happens in the brain as Alzheimer's disease sets in. The underlying cause is believed to be improper processing of a protein associated with the creation of free radicals that cause oxidative stress.

H2S plays critical role in signaling pathway linked to Alzheimer's and Parkinson's

Something rotten never smelled so sweet. This is what members of a team of scientists at Cold Spring Harbor Laboratory (CSHL) are telling one another as they discuss a new finding they did not expect to make. They have discovered that hydrogen sulfide (H2S) - the flammable, highly toxic gas that we usually associate with the smell of rotten eggs in landfills and sewers - plays an important role in the regulation of a signaling pathway implicated in biological malfunctions linked to Alzheimer's and Parkinson's diseases, among others.

Chemical disruption to key interaction shown to limit metastasis in test mice

Finding ways to counteract or disrupt the invasive nature of cancer cells, called "metastasis," has been a long-term goal of cancer researchers. Now, researchers at Moffitt Cancer Center in Tampa, Fla., have identified an interactive pathway that regulates metastases in some cancers that may be vulnerable to chemical targeting in order to prevent cancer cell proliferation and tumor growth.

Research on pancreatic cancer diagnostic test wins QED award

Hwyda Arafat, M.D., Ph.D., Associate Professor of Surgery at Thomas Jefferson University and co-director of the Jefferson Pancreatic, Biliary and Related Cancers Center, and Mon-Li Chu, Ph.D., Professor and Vice Chair of the Department of Dermatology and Cutaneous Biology, were awarded $200,000 from the University City Science Center's QED Proof of Concept Program for their breakthrough work on a diagnostic test for pancreatic cancer.

Researchers discover how statins promote breakdown of plaque in arteries

In a new study, NYU Langone Medical Center researchers have discovered how cholesterol-lowering drugs called statins promote the breakdown of plaque in the arteries. The study was published online by the journal PLoS One on December 6, 2011.

Link between high tau levels and worse outcome after head trauma

High levels of tau protein in fluid bathing the brain are linked to poor recovery after head trauma, according to a study from Washington University School of Medicine in St. Louis and the Fondazione IRCCS Ca Granda-Ospedale Maggiore Policlinico in Milan, Italy.

Scientists shed light on 3-D structure of olfactory receptor binding site

Banana, mango or apricot - telling these smells apart is no problem for the human nose. How the olfactory organ distinguishes such similar smells has been uncovered by an interdisciplinary team of researchers at the RUB. The scientists were the first to shed light on the dynamics of the three-dimensional structure of the binding site of an olfactory receptor. In so doing, they also found a characteristic pattern of hydrogen bonds between odorant and receptor, which accounts for the specificity of the olfactory sensors.

Older women may face negative consequences with weight regain after loss

The holidays are upon us and, for many Americans that means some degree of weight gain and the subsequent New Year's resolution to diet. However, shedding the pounds may have some negative consequences on the overall health of older women if the weight loss is not maintained, according to a new study by researchers at Wake Forest Baptist Medical Center.

Researchers create vaccine that reduces tumors in mice

Researchers at Mayo Clinic in Arizona and the University of Georgia (UGA) have developed a vaccine that dramatically reduces tumors in a mouse model that mimics 90 percent of human breast and pancreatic cancer cases - including those that are resistant to common treatments.

NYUCI experts present latest research findings about hematologic cancers at 53rd ASH meeting

Experts from the NYU Cancer Institute, an NCI-designated cancer center at NYU Langone Medical Center, presented their latest research findings about hematologic cancers at the 53rd ASH Annual Meeting and Exposition held December 10-13, 2011 in San Diego, California.

Aethlon Hemopurifier can capture Nef protein exosomes linked with HIV

Aethlon Medical, Inc., the pioneer in developing therapeutic filtration devices to address infectious disease and cancer, announced today that researchers have discovered that the Aethlon Hemopurifier is able to capture particles known as Nef protein exosomes, which contribute to the progression of human immunodeficiency virus (HIV) infection to acquired immunodeficiency syndrome.

People with myotonic muscular dystrophy more likely to develop cancer

People who have the most common type of adult muscular dystrophy also have a higher risk of getting cancer, according to a paper published today in the Journal of the American Medical Association.

Matrix protein tenascin C regulates astrocyte development

How astrocytes, certain cells of the nervous system, are generated was largely unknown up to now. Bochum's researchers have now investigated what influence the cell environment, known as the extracellular matrix, has on this process.

Scientists identify gene mutation behind Waldenstrom's macroglobulinemia

Scientists at Dana-Farber Cancer Institute have identified a gene mutation that underlies the vast majority of cases of Waldenstrom's macroglobulinemia, a rare form of lymphoma that has eluded all previous efforts to find a genetic cause.

DNA sequencing identifies new altered genes that drive CLL

The most comprehensive search to date of DNA abnormalities in chronic lymphocytic leukemia (CLL) has unearthed several new altered genes that drive this common blood cancer, a finding that could potentially help doctors predict whether an individual patient's disease will progress rapidly or remain indolent for years, say scientists from Dana-Farber Cancer Institute and the Broad Institute.
