Transcription factor Lyl-1 critical in producing early T-cell progenitors

HOUSTON - (July 8, 2012) – A transcription factor called Lyl-1 is necessary for production of the earliest cells that can become T-cells, critical cells born in the thymus that coordinate the immune response to cancer or infections, said a consortium of researchers led by those from Baylor College of Medicine (www.bcm.edu) in a report in the journal Nature Immunology.

Keeping the flu away

San Diego State University researchers at the Donald P. Shiley BioScience Center may have found the secret to helping the immune system fight off the flu before it gets you sick.

A new study published today in the Public Library of Science journal PLoS ONE, finds that EP67, a powerful synthetic protein, is able to activate the innate immune system within just two hours of being administered.

UC Davis study finds that above-normal weight alone does not increase the short-term risk of death

(SACRAMENTO, Calif.) — An evaluation of national data by UC Davis researchers has found that extra weight is not necessarily linked with a higher risk of death.

When compared to those with normal weight, people who were overweight or obese had no increased risk of death during a follow-up period of six years. People who were severely obese did have a higher risk, but only if they also had diabetes or hypertension.

Scientists develop mouse model that could lead to new therapies for liver cancer

Richmond, Va. (July 6, 2012) – Researchers have created the first mouse model demonstrating the role of a cancer promoting gene, Astrocyte elevated gene-1 (AEG-1), in hepatocellular carcinoma, or liver cancer. The mouse model represents a critical step in understanding the molecular mechanisms of liver cancer progression and could lead to novel therapies for the disease.

Antibodies from rabbits reduce risks associated with leukemia

Richmond, Va. (July 9, 2012) –Researchers at Virginia Commonwealth University (VCU) Massey Cancer Center's Bone Marrow Transplant Program have demonstrated that the use of antibodies derived from rabbits can improve the survival and relapse outcomes of leukemia and myelodysplasia patients receiving a stem cell transplant from an unrelated donor.

Fertility drug usage and cancer risk

Women using fertility drugs who did not conceive a 10-plus week pregnancy were at a statistically significant reduced risk of breast cancer compared to nonusers; however, women using the drugs who conceived a 10-plus week pregnancy had a statistically significant increased risk of breast cancer compared to unsuccessfully treated women, but a comparable risk to nonusers, according to a study published July 6 in the Journal of The National Cancer Institute.

Zebrafish provide insights into causes and treatment of human diseases

BETHESDA, MD – July 6, 2012 – Zebrafish, popular as aquarium fish, now have an important place in research labs as a model organism for studying human diseases.

At the 2012 International Zebrafish Development Conference, held June 20-24 in Madison, Wisconsin, numerous presentations highlighted the utility of the zebrafish for examining the basic biological mechanisms underlying human disorders and identifying potential treatment approaches for an impressive array of organ and systemic diseases.

Algae extract increases good cholesterol levels, Wayne State research finds

Detroit - A Wayne State University researcher has found that an extract from algae could become a key to regulating cardiovascular disease.

In a study funded by Health Enhancement Products of Bloomfield Hills, Mich., Smiti Gupta, Ph.D., assistant professor in the department of nutrition and food science in the College of Liberal Arts and Sciences, has found that dietary intake of ProAlgaZyme increased the level of high-density lipoprotein (HDL) in an animal model.

Zebrafish reveal promising mechanism for healing spinal cord injury

BETHESDA, MD – July 6, 2012 – Yona Goldshmit, Ph.D., is a former physical therapist who worked in rehabilitation centers with spinal cord injury patients for many years before deciding to switch her focus to the underlying science.

"After a few years in the clinic, I realized that we don't really know what's going on," she said.

Finding right meditation technique key to user satisfaction

SAN FRANCISCO, July 6, 2012 -- New to meditation and already thinking about quitting? You may have simply chosen the wrong method. A new study published online July 7 in EXPLORE: The Journal of Science and Healing highlights the importance of ensuring that new meditators select methods with which they are most comfortable, rather than those that are most popular.

Adenosine discovery is possible treatment to reduce scarring

Bethesda, MD—Whether from surgery or battle wounds, ugly scars can affect body and mind. Now a new research report appearing online in the FASEB Journal offers a new strategy to reduce or eliminate scars on the skin. Specifically, scientists from NYU describe how agents that block receptors for adenosine (a molecule generated from ATP which is used by the body to provide energy to muscles) can be applied topically to healing wounds to reduce scar size, yielding skin that feels more like the original, unscarred skin.

Heat, rainfall affect pathogenic mosquito abundance in catch basins

Rainfall and temperature affect the abundance of two mosquito species linked to West Nile Virus in storm catch basins in suburban Chicago, two University of Illinois researchers report.

Marilyn O'Hara Ruiz, a professor of pathobiology, led the study with graduate student Allison Gardner.

BWH researchers discover new vaccine candidate for Pseudomonas aeruginosa

BOSTON, MA—Researchers at Brigham and Women's Hospital (BWH) have discovered a new vaccine candidate for the bacterium Pseudomonas aeruginosa taking advantage of a new mechanism of immunity.

The study was published online in the American Journal of Respiratory and Critical Care Medicine on June 21, 2012.

Scientists discover an epigenetic cause of osteoarthritis

Bethesda, MD—In what could be a breakthrough in the practical application of epigenetic science, U.K. scientists used human tissue samples to discover that those with osteoarthritis have a signature epigenetic change (DNA methylation) responsible for switching on and off a gene that produces a destructive enzyme called MMP13. This enzyme is known to play a role in the destruction of joint cartilage, making MMP13 and the epigenetic changes that lead to its increased levels, prime targets for osteoarthritis drug development.

E-waste: Annual gold, silver 'deposits' in new high-tech goods worth $21B; less than 15% recovered

A staggering 320 tons of gold and more than 7,500 tons of silver are now used annually to make PCs, cell phones, tablet computers and other new electronic and electrical products worldwide, adding more than $21 billion in value each year to the rich fortunes in metals eventually available through "urban mining" of e-waste, experts say.
