Shedding new light on proteorhodopsin

...orhodopsin. For this the researchers will need to identify the most efficient forms of the protein, then manipulate microbial genomes through the addition or deletion of key genes. ...

Research on grey mould offers possible breakthrough in tomato cultivation

...ep scan of the entire genome of the wild tomato to identify locations that have an effect on resistance. Ten areas were found that accommodated resistance factors against grey mould. DNA-markers were then developed for each area to be able to track the presence of each resistance factor in breeding programmes...

Childhood obesity among Quebec Cree raises concerns

... diseases and diabetes. Further study is needed to identify the causes behind the high obesity rates, but in general, the elementary school students exhibited very low levels of physical fitness and physical activity. Diet is another obvious possibility to consider. This University of Alberta research is o...

Autism gene identified by researchers at Yale working with a global research consortium

... a global research consortium from 19 countries to identify a gene and a region of a chromosome that may lead to autism in children. The findings are published online today in Nature Genetics and also will be published in the journal’s March print edition. They are based on the largest-ever autism genome sca...

ATR checkpoint-activating DNA structure

...the ATR checkpoint will aid researchers to further identify additional checkpoint proteins, as well as understand how checkpoint signals are generated and regulated inside the cell....

Why doesn't the immune system attack the small intestine?

...igators led by Shannon Turley, PhD, of Dana-Farber identify an unlikely group of peacemakers: lymph node cells that instruct key immune system cells to leave healthy tissue alone. The finding, which illuminates a previously unknown corner of the human immune system, may lead to new forms of treatment for auto...

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

...nvestigator on the research. “Having the tools to identify hepatocellular 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 incl...

Novel antigen-cloning technique may boost efforts to develop a melanoma vaccine

...antigens for vaccine development. In working to identify a key tumor antigen in melanoma and other cancers,...rlyn's group has used the new cloning technique to identify a new tumor antigen called ribosomal protein L8, or RPL8. Findings on the new cloning method and the...

Infection detectives use disease 'fingerprints' to track common infections in children

...similar to a disease "fingerprint" ?and be able to identify which infection was present. The process to identify such biosignatures is called gene expression profiling, and it’s done using microarray analysis. ...

Scientists use nanoparticle to discover disease-causing proteins

...ne of the stable isotopic or fluorescent labels to identify the presence or absence of a protein that can be further developed for use as a disease indicator, or biomarker. Snake venom cells were used because they have a very high concentration of proteins similar to some found in human blood, Tao said. Th...

UW launches study testing adult stem cells for heart damage repair

...eart with a catheter-based, non-surgical system to identify regions of the heart as targets for cell delivery. The researchers then use a special investigational catheter system to deliver either CD34+ cells or placebo into areas of the heart that have poor blood flow. Subjects are randomly selected to recei...

Scientists find new genes for Crohn's disease

Elucidation of the genome for diabetics with DNA chips

...uce. The team of Philippe Froguel was the first to identify a gene associated with DT2 ?that encoding glucokinase ?in 1992. Several other such genes have since been discovered, but together these genes account for only a small proportion of DT2 cases. Insufficient knowledge of the human genome and the absence...

Homing pigeons get their bearings from their beaks

...dependent of their motion and posture and thus can identify their geographical position. The researchers further believe that this ability is not unique to homing pigeons as they expect that the ‘pigeon-type receptor system ?might turn out to be a universal feature of all birds? Equally, this concept migh...

What's in the water? Estrogenic activity documented in fish caught in Pittsburgh's rivers

... to Dr. Volz, the next step in this research is to identify the estrogenic chemicals and their sources in the local water and fish. "These findings have significant public health implications, since we drink water from the rivers where the fish were caught. Additionally, the consumption of river-caught fish, ...

Scientists unveil piece of HIV protein that may be key to AIDS vaccine development

...nuously—defeating attempts by the immune system to identify and destroy it—the virus is also swathed by sugary molecules. This nearly impenetrable sugar cloak prevents antibodies from slipping in and blocking the proteins the virus uses to latch onto a cell and infect it. In 1998, Dr. Kwong and colleagu...

He's also raising the grasshoppers in his lab, with Junek supplying nymphs she has already found this year. Junek is also ...

Lost dogs found more often than lost cats, study suggests

...where a pet belongs. Cat owners aren't required to identify their pet, and 19 percent of lost cats had a tag or microchip at the time they were lost. More than half of the cats returned on their own, but less than one in 10 dogs did. The results of the two studies appear in the January 15 issue of the Jou...

OHSU lab finds meth receptor that could lead to therapy
