HIV-1 spread through six transmission lines in the UK

...came widely used if this was the case. Instead, we see little correlation between widespread availability of treatment and reduction of transmission. This is highly pertinent to the recent increase again in new HIV-1 diagnoses within the UK . “Our study also contradicts assumptions that the HIV-1 epidem...

Multi-purpose protein regulates new protein synthesis and immune cell development

... to create plasma cells, Zhang designed a study to see if IRE1 was involved, also. Zhang studied mouse embryos that were missing the gene for IRE1. He found that mice lacking both copies of IRE1 died before birth and had fewer hematopoietic stem cells ?precursor cells which develop into many different t...

Gene therapy promising for growing tooth-supporting bone

...ile added. He said he optimistically would like to see initial trials begin in humans in four to seven years. BMP-7 is part of a family of proteins that regulates cartilage and bone formation. Recent studies have shown that BMPs are present in tooth development and periodontal repair. This study mixed ...

Nanoparticles offer new hope for detection and treatment

... the nanoparticles, we believe we would be able to see the smallest melanoma tumors when they are just large enough to begin new blood vessel formation. Plus, we should be able to deliver chemotherapeutic drugs right to melanoma cells, because melanoma tumors create blood vessels using their own cells." ...

Researchers make gains in understanding antibiotic resistance

...ature, stating that hospitals in the United States see some two million cases of antibiotic-resistant infections each year; 90,000 patients die annually from such infections. In their experiments, Steitz and his colleagues used x-ray crystallography to do high-resolution structural analyses of the large...

Revolutionary nanotechnology illuminates brain cells at work

Growth in biomass could put US on road to energy independence

...port. Such an increase in ethanol production would see transportation fuels from biomass increase from 0.5 percent of U.S. consumption in 2001 to 4 percent in 2010, 10 percent in 2020 and 20 percent in 2030. In fact, depending on several factors, biomass could supply 15 percent of the nation's energy by ...

Different microarray systems more alike than previously thought

...Hopkins Bloomberg School of Public Health. "Now we see the possibility that it may not make much difference as long as the systems are used properly and the results reported properly." The impact of such a finding is not insignificant, experts say, because these systems may ultimately allow scientists t...

Brain Scans Reveal How Gene May Boost Schizophrenia Risk

...ature pattern of midbrain dopamine activity.** To see how the two gene versions affect the living human brain, the NIMH researchers scanned 24 healthy young adults twice using PET (positron emission tomography), which uses radioactive tracers to visualize brain function. The first scan measured subjects...

Shift of weather patterns necessitates rethinking of reforestation methods

... Service analysis of 100 years of weather data, we see a cyclical pattern of 25 years of summers that are either hot and drier or cooler and wetter than average," he said. "We're now in about year eight of a 25-year hot-and-dry cycle. That doesn't mean every year will be hot and dry. The last two years w...

Scientists journey to southern Africa to unravel the secret world of elephant communication

Insight into DNA's 'weakest links' may yield clues to cancer biology

...hers. "If you look at solid tumors in humans, you see that the chromosomes of cancer cells exhibit incredible instability," said Thomas Petes, Ph.D., chair of genetics and microbiology at Duke. "Now, we have been able to mimic some of that instability in yeast cells and can begin to ask whether there is...

The evolutionary triumph of flower power

...for the incredible variety of shapes and colors we see in domesticated flowers today. McGuire suggests that nature's prettier flowers got to survive and thrive because people didn't destroy them when they cleared land for agriculture. Instead, they cultivated them and have been doing so for more than 5,0...

Genetic therapy reverses nervous system damage in animal model of inherited human disease

...y in infants," Wolfe said. "In our study, we could see that gene therapy used during this particular time...mannosidosis using imaging allows the clinician to see improvement in brain pathology without the need for brain biopsy." "Lysosomal storage diseases are ...

Oceans more vulnerable to agricultural runoff than previously thought, study finds

...n events per year, and right after each one, you'd see a bloom appear within a matter of days." Each bloom was enormous, he said, covering from 19 to 223 square miles (50 to 577 square kilometers) of the gulf and lasting several days. "Sometimes eddies actually pulled the plumes across the gulf, from th...

Study reveals dramatic difference between breast cancers in US and Africa

...ply to the types of breast cancer we most commonly see in African women." The researchers studied the pattern of gene expression -- a measure of which genes were turned on and active -- in breast cancer tissue from 378 women in Nigeria and Senegal. They compared the results with a database of breast can...

Road salt affects mitigation wetlands

Compounds in plastic packaging act as environmental estrogens altering breast genes

...dies of BPA and BBP in young rats were designed to see whether exposure to these hormonally active biological compounds could alter the genomic signatures of the mammary gland during critical stages of development." BPA (bisphenol A) is a synthetic resin used in food packaging, dental sealants and polyca...

Migratory songbirds have a specialized night-vision brain area

...s of miles at night, night-migratory birds need to see where they fly, as well as navigate by stars and the earth's magnetic field. Surprisingly, Jarvis said, recent scientific evidence has suggested that birds have specialized molecules in their visual system that translate magnetic compass information ...
