Research identifies protein that signals flowering in squash plants

...ta squash species because reliable methods for the analysis of translocation through the phloem stream have been developed in this system. However, most cucurbits are day-neutral plants, and to investigate the nature of the florigenic signal effectively, it was essential to utilize an obligate SD plant. In da...

Liver cancer patients with high serum levels of hepatitis B virus face poorer outcomes

...igns and symptoms. They then performed statistical analysis to assess which factors might have influenced patient outcomes. The median survival of all patients was 6.83 months. Patients with high pre-treatment HBV DNA had a significantly higher incidence of developing severe hepatitis during chemotherapy a...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...he recent work much more challenging. Already, analysis of these three anti-malarial drug resistance genes is painting a picture of how the parasite escapes destruction by most of the agents now used against it, he said., When a malaria parasite is transmitted through a mosquito bite, the mosquito in...

New study finds genetically engineered crops could play a role in sustainable agriculture

... plants have on other non-modified species. In an analysis of 42 field experiments, scientists found that thi...disciplinary research team reveals how an in-depth analysis of large quantities of existing data from many individual experiments can provide a greater understa...

Research shows cord blood comparable to matched bone marrow

...omes than bone marrow transplants, according to an analysis of outcome data performed at the Center for Intern...rd Blood Program at the New York Blood Center. The analysis included transplant outcomes in 785 children younger than 16 who had the diagnosis of acute lymphobl...

New findings challenge established views on human genome

...and, who led ENCODE’s massive data integration and analysis effort. The ENCODE consortium’s major findings include the discovery that the majority of DNA in the human genome is transcribed into functional molecules, called RNA, and that these transcripts extensively overlap one another. This broad pattern...

454 sequencing identifies HIV drug resistance at early stage

...CT Health Care System, was a blinded-retrospective analysis of 258 blood samples taken before drug treatment from HIV infected individuals. The results were presented today at the XVI International HIV Drug Resistance Workshop in Barbados and showed that the fraction of patients that harbored resistance mutat...

Research finds that circadian rhythms dominate all life functions

...o State University researcher Andrey Ptitsyn's new analysis of data collected through several studies establishes a baseline oscillation in 98 to 99 percent of all genes through advanced computer algorithms. Most of these genes have never been previously reported as changing their expression level in a daily ...

Reconstructing the biology of extinct species: A new approach

Human genetic 'deserts' are teeming with significant life

...d Spain, now intends to carry out the same kind of analysis for two complete human chromosomes. “I will be surprised if we do not find the same kind of variety in these structures”, he says. “Our work has shown that the human genome is far more complex than anyone could have imagined, even ten years ago. ...

Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state

...gulator gene Oct4. They also applied very rigorous analysis methods, using data from StemBase, the largest stem cell gene expression database in the world. Designed by bioinformaticist Dr. Miguel Andrade, the database includes data from thousands of DNA microarrays submitted mainly by scientists in Canada’s S...

Scientists close in on missing carbon sink

...phere to be absorbed in other regions. But the new analysis of aircraft samples shows that this is not the case. "With this new information from aircraft samples we see that the models were overestimating the amount of uptake in the north and underestimating uptake in the tropics," says Kevin Gurney of Pur...

Experts predict Tamiflu could halve the pandemic influenza death toll versus no intervention

...fluenza.1 This research is supported by an earlier analysis that indicates that a prevention strategy using Tamiflu may help contain a pandemic outbreak.3 The study also predicts that if the stockpile is increased so that there is an unlimited supply of Tamiflu for treating symptomatic patients and for pr...

Antarctic icebergs -- Hotspots of ocean life

... information in collections at SDSC for access and analysis by scientists now and in the future. Just getting to the icebergs was a challenge. First the scientists used satellite images to select two icebergs to study in detail. Then they sailed aboard the Antarctic research vessel Laurence M. Gould to re...

Eavesdropping comes naturally to young song sparrows

... song sparrows by radio in the field. Preliminary analysis of the tracking data suggests that young birds don’t have many direct interactions with adults, and so are likely to be learning their songs by eavesdropping. When it comes to research about how babies learn language, most work has focused on inte...

First confirmed common genetic risk factors for breast cancer

The most powerful genetic analysis of the DNA codes of over 40,000 women -- including those with breast cancer as well as those without the disease – has uncovered five common genetic variants that increase an individual’s risk for breast cancer. In a paper published online today in...

Extra-aggressive form of idiopathic pulmonary fibrosis identified

...study the authors performed global gene expression analysis and other molecular studies in a subset of patients and identified a number of genes that were differentially expressed in both groups, suggesting that rapid progressors are biologically distinct from slow progressors. "While preliminary, these r...
