Mailman School of Public Health researchers report blood DNA can be early predictor of liver cancer

...tocellular carcinoma at earlier stages, is truly a breakthrough for addressing the challenges that result from this highly lethal form of cancer.? Dr. Santella and the team of researchers previously found that several environmental factors including aflatoxin B1, a dietary mold contaminant sometimes found in pe...

Scientists discover new, readily available source of stem cells

...ersity School of Medicine. Atala announced the breakthrough with colleagues from Wake Forest University School of Medicine and Harvard Medical School. "It has been known for decades that both the placenta and amniotic fluid contain multiple progenitor cell types from the developing embryo, including fat, b...

Protein fragments sequenced in 68 million-year-old Tyrannosaurus rex

...participated in the study. "Basically, this is the breakthrough that says it’s possible to get sequences beyond one million years. At 68 million years, it’s still possible to get sequences," he said. In addition to the seven dinosaur sequences, Asara and his colleagues isolated and sequenced more than 70 protein ...

A new study of living cells could revolutionize the way we test drugs

Researchers have made a breakthrough by detecting the electrical equivalent of a living cell’s last gasp. The work takes them a step closer to both seeing the ‘heartbeat?of a living cell and a new way to test drugs. To stay alive, individual biological cells must transfer electrically...

Breakthrough vaccine to treat chemo-resistant ovarian cancer

...sease and brings hope to women everywhere." The breakthrough treatment method uses the patient's own tumor tissues to create a patient-specific vaccine and is combined with chemotherapy delivered directly into the abdominal cavity. Ovarian cancer, one of the hardest cancers to detect in the early stages, i...

NT researchers discover breakthrough in malaria treatment

...of Health Research (MSHR) in Darwin has revealed a breakthrough in the battle to treat Malaria ?a disease which effects 40 per cent of the worlds population. There are two major strains of malaria effecting humans, P. vivax and P. falciparum. Although attention focuses on the more virulent P. falciparum, vivax...

Beyond the DNA: Chemical signatures reveal genetic switches in the genome

...a, San Diego (UCSD) School of Medicine have made a breakthrough in identifying functional elements in the human genome, according to a report published online today in Nature Genetics. While the DNA sequence can identify genes (the 'what') within the genome, it cannot answer the more fundamental questions of 'h...

Stanford-led study closes in on genes that may predispose some people to severe depression

... researchers from six universities, achieved this breakthrough by studying 650 families in which at least two members suffered from repeated bouts of severe depression that began in childhood or early adult life. The first of the studies was a genome-wide scan that looked for evidence of genetic "linkage" ...

Cure for cancer one step closer

...vable by the Tissue Bank will lead to the next big breakthrough in the fight against cancer," she said. "By providing researchers who are part of an ethically and scientifically approved research project with tissue, matching blood samples and full clinical data, valuable funds will be saved, which can then be...

NIDA study identifies genes that might help some people abstain from smoking

...se a person’s ability to abstain from smoking. The breakthrough research was conducted by Dr. George Uhl at NIDA’s Intramural Research Program and a team led by Dr. Jed Rose at the Center for Nicotine and Smoking Cessation Research at Duke University Medical Center. The study, published in the journal BMC Geneti...

Iowa State scientists demonstrate first use of nanotechnology to enter plant cells

...rs its expression with controlled precision. Their breakthrough brings nanotechnology to plant biology and agricultural biotechnology, creating a powerful new tool for targeted delivery into plant cells. The research, "Mesoporous Silica Nanoparticles Deliver DNA and Chemicals into Plants," is a highlighted arti...

First confirmed common genetic risk factors for breast cancer

...14, MAP3K1, and LSP1. "This is a truly landmark breakthrough for breast cancer research, because these genes are the first confirmed common genetic risk factors for breast cancer," said Dr. Liu. As common genetic risk factors, these genes likely have more impact than the previously identified risk genes on ...

Plastic that grows on trees

..., 100 degrees centigrade. “This, in my view, is breakthrough science in the renewable energy arena,” said J.M. White, IIC director and Robert A. Welch chair in materials chemistry at the University of Texas. “This work opens the way for fundamental catalysis science in a novel solvent.” The chemistry at wor...

Research team identifies new Alzheimer's gene
