HDE and DEP exposure can lead to development of asthma

A study conducted by researchers at Boston University School of Medicine (BUSM) has found that diesel exhaust particulates (DEP) and house dust extract (HDE) causes pulmonary inflammation that aggravates asthma.

Researchers discover novel viral oncogenesis mechanism

Human tumor viruses contribute to 15-20% of human cancers worldwide. Kaposi's sarcoma herpesvirus (KSHV) is an etiological agent for Kaposi's sarcoma (KS) and two other rare lymphoproliferative malignancies. KS is the most common cancer in HIV-infected untreated individuals and remains a primary cause of cancer deaths in many subequatorial African countries as a result of the AIDS pandemic.

DCC gene protects mice from onset of colon cancer

The research team at Lyon has developed an animal model carrying a mutation of the DCC gene. Mice carrying the mutation develop tumours, because this gene can no longer induce the death of the cancer cells. This discovery could lead to the development of a new targeted cancer treatment that aims to reactivate the dying of cancer cells.

Ganitumab shows promise in early-phase trials for metastatic pancreatic cancer

Over 17,000 patients will have been diagnosed with locally-advanced pancreatic cancer in the United States in 2011. Surgery is not a treatment option for these patients whose tumor has grown beyond the pancreas to surrounding vital structures.

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.

Fresh cells can pep talk immune cells exhausted by HIV or hepatitis C

Chronic infections by viruses such as HIV or hepatitis C eventually take hold because they wear the immune system out, a phenomenon immunologists describe as exhaustion.

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.

Textile cushions with smart sensor systems for persons confined to bed or wheelchair

Anyone confined to a wheelchair or a bed has to deal with numerous complications. Frequently, they suffer from bedsores or decubitus ulcers as physicians call them. Bony prominences, such as the sacrum, coccyx and ischium, are especially endangered spots. Unrelieved pressure can lead to tissue necrosis. Damage can extend into the periosteum and, at the worst, into bones themselves.

Hydrogel regenerates healthy, scar-free tissue on skin damaged by severe burns

Johns Hopkins researchers have developed a jelly-like material and wound treatment method that, in early experiments on skin damaged by severe burns, appeared to regenerate healthy, scar-free tissue.

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.

Maraviroc reduces incidence of GvHD in blood cancer patients after ASCT

An HIV drug that redirects immune cell traffic appears to significantly reduce the dangerous complication graft-versus-host disease (GvHD) in blood cancer patients following allogeneic stem cell transplantation (ASCT), according to new research from the Perelman School of Medicine at the University of Pennsylvania that will be presented today at the 53rd American Society of Hematology Annual Meeting.

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.

New study: Insulin signaling is altered in human pancreas

Insulin signaling is altered in the pancreas, a new study shows for the first time in humans. The errant signals disrupt both the number and quality of beta cells - the cells that produce insulin.

Canadian researchers develop portable device to monitor HIV in rural areas

A team of Canadian researchers has "created a portable device that uses a computer chip with software capable of analyzing blood tests outside the lab ... that could make it easier, faster and cheaper to track the progression of HIV in patients living in the developing world," Postmedia News/Vancouver Sun reports.

Promising results from Fate Therapeutics' ProHema Phase 1b trial on hematologic malignancies

Fate Therapeutics, Inc. announced today promising clinical results from a Phase 1b trial of ProHema (FT1050-enhanced umbilical cord blood) as part of double-umbilical cord blood (UCB) transplants in adult patients with hematologic malignancies who have undergone reduced-intensity conditioning therapy.

GW scientist to identify molecular mechanisms that define embryonic OE stem cells

Anthony-Samuel LaMantia, PhD, professor in the Department of Pharmacology and Physiology and Director of the GW Institute for Neuroscience in the School of Medicine and Health Sciences has been awarded a grant from the National Institutes of Health to identify molecular mechanisms that define embryonic olfactory epithelium (OE) stem cells.

CTI, Chroma announce final results from tosedostat phase II study on AML

Cell Therapeutics, Inc. and Chroma Therapeutics Ltd. announced that final results from the phase II OPAL study of tosedostat in elderly patients with relapsed or refractory acute myeloid leukemia (AML) were presented by Jorge Cortes, M.D. of the University of Texas M.D. Anderson Cancer Center during the Acute Myeloid Leukemia - Therapy, excluding Transplantation: Clinical Studies session at the American Society of Hematology Annual Meeting.

Nighttime satellite images could provide clues to disease outbreaks, researchers suggest

"The intensity of light shining from cities at night could help identify hot spots where outbreaks of infectious disease are likely to take place," PBS NewsHour's "The Rundown" reports.

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.
