Cross-species malaria immunity induced by chemically attenuated parasites

Malaria, a mosquito-born infectious disease, kills over 600,000 people every year. Research has focused on the development of a vaccine to prevent the disease; however, many malaria vaccines targeting parasite antigens have failed because the antigen targets are highly variable.

How the body aids and abets the spread of cancer

Montreal, July 1st 2013 – The very system that is meant to protect the body from invasion may be a traitor. These new findings of a study, led by investigators at the Research Institute of the McGill University Health Centre (RI-MUHC), reveal that infection-fighting white blood cells play a role in activating cancer cells and facilitating their spread to secondary tumours. This research, published today in the Journal of Clinical Investigation has significant implications for both the diagnosis and treatment of cancer.

GW researcher discovers new regulatory autism gene

WASHINGTON -- A new study by Valerie Hu, Ph.D., professor of biochemistry and molecular medicine at the George Washington University (GW) School of Medicine and Health Sciences (SMHS), reports that RORA, a novel candidate gene for autism discovered by her group in a 2010 study, regulates a large number of other genes associated with autism.

"We are focusing on this gene, in part, because this gene can act as a master regulator of other genes," said Hu, whose study was published in the journal Molecular Autism.

Gene mutations caused by a father's lifestyle can be inherited by multiple generations

Bethesda, MD -- Gene mutations caused by a father's lifestyle can be inherited by his children, even if those mutations occurred before conception. What's more, these findings show that mutations in the germ-line are present in all cells of the children, including their own germ cells. This means that a father's lifestyle has the potential to affect the DNA of multiple generations and not just his immediate offspring. These findings were published in the July 2013 issue of The FASEB Journal.

Fat grafting techniques for breast reconstruction are commonly used by US plastic surgeons

Philadelphia, Pa. (July 1,2013) – Seventy percent of U.S. plastic surgeons have used fat grafting techniques for breast operations, but they are more likely to use it for breast reconstruction rather than cosmetic breast surgery, reports a survey study in the July issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).

Getting kids to eat their veggies: A new approach to an age-old problem

Every parent has a different strategy for trying to get his or her kid to eat more vegetables, from growing vegetables together as a family to banning treats until the dinner plate is clean. New research suggests that teaching young children an overarching, conceptual framework for nutrition may do the trick.

Study finds biochemical role of crucial TonB protein in bacterial iron transport and pathogenesis

MANHATTAN, Kan. -- A Kansas State University-led study has discovered the role of a protein in bacteria that cause a wide variety of diseases, including typhoid fever, plague, meningitis and dysentery. The results may lead to new and improved antibiotics for humans and animals.

Harvard and USC scientists show how DHA resolves inflammation

Bethesda, MD—Chronic inflammation is a major factor in a wide range of problems from arthritis to cardiovascular disease, and DHA (found in fish oil) is known to temper this problem. A new research report appearing in the July 2013 issue of The FASEB Journal, helps explain why DHA is important in reducing inflammation, and provides an important lead to finding new drugs that will help bring people back to optimal health.

Breakthrough discovery into the regulation of a key cancer drug target

There's not much difference between what makes a man and what makes his beer - at least at the molecular level - according to a new study led by Professor John Schwabe at the University of Leicester.

Scientists used a powerful technique called protein crystallography to look at 3D structures of protein complexes purified from cultured human cells. They discovered that a family of complexes, that switch off gene expression, is regulated by small signalling molecules called inositol phosphates.

Neuroblastoma: Autophagy protects from chemotherapy

Neuroblastomas are pediatric tumors that originate from cells of the embryonic nervous system. The disease can take widely varying clinical courses that range from spontaneous regression to fatal outcomes. Highly aggressive neuroblastomas rarely respond well to chemotherapy. Understanding and overcoming the resistance mechanisms of highly aggressive neuroblastomas are considered essential to the development of effective treatments.

Too much of a good thing? Too many 'healing' cells delays wound healing

Bethesda, MD -- Like most other things, you can have too much of a good thing when it comes to wound healing, and new research proves it. According to an article published in the July 2013 issue of the Journal of Leukocyte Biology, wound healing can be delayed because the body produces too many mast cells, which normally promote healing. An overabundance of these cells, however, also causes harm by leading to the overproduction of IL-10, which prevents certain white blood cells from reaching the wounded area.

Social responsibility, the main motivation of minority-language radio journalism

The UPV/EHU researcher Irati Agirreazkuenaga-Onaindia has developed a new methodology for studying the profiles, working habits and perceptions of Basque and Scottish Gaelic-speaking radio journalists. The study confirms that social responsibility is the main motivation for the EITB and BBC journalists.

New guidelines pave the road for achieving an AIDS-free generation

KUALA LUMPUR—July 1, 2013—The Elizabeth Glaser Pediatric AIDS Foundation (EGPAF) welcomes the World Health Organization (WHO)'s new HIV/AIDS treatment and prevention guidelines. For the first time, the 2013 guidelines combine recommendations across the continuum of HIV care and prevention programs, including expanding treatment eligibility for HIV-positive pregnant women, mothers, and children. These recommendations signify a major step forward in the global effort to achieve an AIDS-free generation, but will require a significant shift in current implementation efforts.

ACRG and BGI report new evidence for the genetic bases of liver cancer

July 1, 2013, Shenzhen, China – The Asian Cancer Research Group (ACRG), an independent, not-for-profit company in collaboration with BGI, the world's largest genomics organization, and The University of Hong Kong (HKU), jointly announced the publication of findings from a study of recurrent mutations in hepatocellular carcinoma (HCC), one of the most deadly cancers worldwide, in the international journal Genome Research. The study provides new insights into potential therapeutic intervention strategies for this common form of liver cancer.

DNA particles in the blood may help speed detection of coronary artery disease

DALLAS, July 1, 2013 — DNA fragments in your blood may someday help doctors quickly learn if chest pain means you have narrowed heart arteries, according to a new study published in the American Heart Association journal Arteriosclerosis, Thrombosis, and Vascular Biology.
