Reactivated gene shrinks tumors

...of tumor when p53 turns back on. The study also revealed that turning on p53 has no damaging effects in normal cells. The researchers had worried that p53 would kill normal cells because it had never been expressed in those cells. "This means you can design drugs that restore p53 and you don't have to w...

A first glimpse of the influenza replication machine

Ring-around-the-cell

...ently appeared in the online journal PLoS ONE, has revealed in unprecedented detail how the roving cells whose job is to digest bone seal off their work area as they get down to business. The cells, called osteoclasts, have some unique features not seen in any other cell type. Osteoclasts move around the bon...

Growth hormone to boost athletic performance risks diabetes

...d sugar (hypoglycaemia) while at the gym. Tests revealed that his liver was inflamed, his kidneys were enlarged and that he had very high blood sugar. He was also dehydrated, and diagnosed with diabetes. He was given intravenous fluids and gradually increasing amounts of insulin over five days, after wh...

Non-GMO solution to seafood allergies

...esearch at the Ocean University of China. The team revealed that treating prawns with a combination of heat and irradiation significantly reduced the level of reactive proteins called allergens. They took blood from patients with shrimp allergies, added samples of treated and untreated prawn, and measured how...

Groundbreaking Canadian asthma study

...McMaster University authored the study. The study revealed improved asthma control at one year following the bronchial thermoplasty procedure. The publication entitled, "Asthma Control during the Year after Bronchial Thermoplasty", showed that patients treated with bronchial thermoplasty, compared to anot...

New approach could lower antibiotic requirements by 50 times

...ospital-acquired infections. Experiments in mice revealed that 75% of those infected with a lethal dose of Pseudomonas survived if the antibiotic gentamicin was administered in the presence of bacteriophages. None survived without the phages (Microb. Drug Resist., 2006, 12 (3), 164). The bacteriophage app...

Cancer cells forming blood vessels send their copper to the edge

...enesis. The dynamics of cellular copper this study revealed also have broad implications on the regulation of the metal ion content in metal-binding proteins. If such dramatic changes in where cellular copper is stored and used can happen so rapidly during angiogenesis, then the interactions of metal ions, su...

Cells selectively absorb short nanotubes

... the solutions. Further examination of the results revealed that only short nanotubes made it into the cellular interior. In the next phase of the research, the team exposed the cells to sorted nanotubes of controlled length. They found that tubes longer than about 200 nanometers were excluded from the cel...

Prion disease treatable if caught early

...disease. Also, studies of the animals?brain tissue revealed a parallel impairment of signaling among brain cells. However, when the researchers manipulated the animals to deplete their brains of the prion protein, their memory ability and burrowing behavior recovered. Importantly, found the researchers, th...

OHSU researchers demonstrate how white blood cells cannibalize virus-infected cells

...ow with the fluorescent dye. Further investigation revealed that the CD8+ T-cells, often referred to as "killer" T-cells, were literally ingesting parts of the virus-infected cells that they were attacking. Slifka and Beadling's findings follow a discovery by David Parker, Ph.D., a professor of Molecular ...

Scientists crack rhino horn riddle

The team examined the heads of rhinos that died of natural causes and were donated by The Wilds in Cumberland, Ohio, and the Phoenix Zoo. Researchers conducted CT scans on ...

Why do cold animals make bigger babies?

So why do animals in colder climates produce larger offspring? One theory suggests the larger size of offspring counteracts their slow growth in ...

Nobel Laureate finds 'elegant' explanation for DNA transcribing enzyme's high fidelity

Record ozone loss during 2006 over South Pole

... measurements made by ESA's Envisat satellite have revealed the ozone loss of 40 million tons on 2 October 2006 has exceeded the record ozone loss of about 39 million tons for 2000. Ozone loss is derived by measuring the area and the depth of the ozone hole. The size of this year's ozone hole is 28 million ...

Evolution of influenza A virus

...ew York State. Comparative analysis of the samples revealed genetically distinct viral strains circulate across the state within any one season and occasionally exchange genes through reassortment. These results indicate that adaptive evolution occurs only sporadically in influenza virus, and that influen...

Underweight women at greater risk of miscarriage
