Shedding new light on proteorhodopsin

...red electrochemical energy. In this respect, it is similar to another protein, bacteriorhodopsin, that's used by bacteria in salt ponds to supplement respiration. However, in experiments in which marine bacteria endowed with proteorhodopsin were exposed to light, there was no response. This begged the quest...

Grape expectations for healthier wine

...ergic reactions in some people. Wine-makers have a similar problem in that the sulphites added to wines to prolong their shelf-life and allow them to age can make their wines unpalatable to some drinkers. Francisco Artes-Hernandez and his team at the Technical University of Cartagena in Spain compared sev...

MU researcher placing eye implants in cats to help humans see

...o use for this type of research because it is very similar to a human eye in size and construction, so surgeo...chnology also may be beneficial for pets that have similar diseases because this technology can benefit both animals and humans."...

Vasectomy may put men at risk for type of dementia

...tibodies that reach the brain and cause an illness similar to encephalitis, she noted. The next step in Weintraub's research will be to launch a national study to see if her results will be confirmed in a larger population. "I don't want to scare anyone away from getting a vasectomy," Weintraub stress...

Yale biologists 'trick' viruses into extinction

...treatments against human viruses," said Turner. "A similar idea already exists in agriculture, where farmers ... amount of pesticide use." Turner believes that similar trickery might be used against human viruses like HIV. He notes that HIV recognizes the T-cells it i...

Scientists use nanoparticle to discover disease-causing proteins

...se they have a very high concentration of proteins similar to some found in human blood, Tao said. The proteins apparently are part of the biochemical process that affects blood clotting or hemorrhage. Understanding how the proteins behave could help determine predisposition to heart disease and cancer and a...

Putting an old drug to a new use

...oad in mouse models and has the potential to treat similar conditions in humans. Our body needs most of its iron to make red blood cells. A lack of the metal can lead to dangerous anemias, but also too much iron can be detrimental as iron promotes the formation of toxic radicals leading to tissue damage. Ir...

Destructive enzyme shows a benevolent side

...e Cancer Center. "By understanding how PMR1 and similar enzymes are incorporated into stress granules and inactivated, we may be able to learn how to block this protective mechanism and make it harder for cancer cells to survive cancer therapies." Schoenberg first discovered the PMR1 enzyme in 1995, an...

Cartilage discovery offers arthritis hope

...ing millimetre-long collagen fibres that work in a similar way to the load-bearing steel rods in reinforced concrete. But the precise structure of these fibres or 'fibrils' has remained a mystery for more than 40 years, so hindering any progress towards the development of potential therapies. Now, a team...

Smoking ban dramatically reduces air pollution in Irish pubs

...lth." If all European countries were to adopt a similar policy, she estimates that between 5 to 10 million premature deaths from smoking could be prevented over the next generation. Although Dr. Godfrey admits that the impact of the Irish ban has been "enormous," she also highlights several "important...

New molecular pathway could reveal how cells stick together

...ction of that protein. She has previously done similar work knocking out MMP in flies. "One of the defects in MMP mutants is in their ability to control cell adhesion," she said. Many tissues undergo remodeling as the flies grow and develop, but at least one, the breathing tubes, do not develop properly ...

Tracing broken wiring in stroke patients

...reen. As a control, the researchers also conducted similar tests on healthy volunteers. The study revealed new details about how functional connectivity within and between different regions of the "attention networks" in the parietal cortex of the brain was disrupted in the brains of the stroke patients. ...

Using brain scans, researchers find evidence for a two-stage model of human perceptual learning

...ences. "In the beginning, all the cars looked very similar to the participants because they did not have any ...n had never seen faces before, they would all look similar at first." In the first experiment, the participants looked at series of cars presented at differ...

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

...s. Of 21 catfish extracts tested, nine displayed a similar ability to bind with the estrogen receptors. The researchers also examined whether the fish extracts could result in growth of breast cancer cells cultured in the laboratory, and they found that two bass extracts produced strong-to-moderate cell grow...

Cancer vaccines -- Taking a jab at cancer by stimulating the immune system

...offered significant protection against genetically similar viruses. They determined the vaccine to be 88 percent effective against HPV type 45 and 54 percent effective against HPV type 31. "Overall, it is not a surprise that the vaccine offers protection against additional types of human papillomavirus, a...

What recognizes what in plant disease resistance?

...-1 receptor homology domain, which is structurally similar to animal innate immunity molecules. These findings provide novel insights into how R proteins recognize pathogen Avr proteins and should help in long-term efforts to enhance crop yield. ...

New study may show how to forestall a fatal, virus-caused immune-system meltdown

...se infected with the other strain develop symptoms similar to those seen in humans infected by the much more dangerous Lassa virus, which can cause an acute hemorrhagic fever and kills about 5,000 people a year in West Africa. (During some Lassa fever epidemics, as many as 50 percent of those diagnosed with ...

White blood cells in lung produce histamine seen in allergies

...nsiderable." The neutrophil-histamine effect was similar in the wild-type mice, reports Caughey: "Histamine levels from neutrophils blew right past the histamine levels contributed by mast cells." The wild-type mice suffered less severe infections overall because "as a number of recent studies, including...

Genes and biomarkers that allow doctors to choose the right therapy for the right patient

..., and their methodologies could aid in identifying similar biomarkers for responses to other drugs and for other types of cancer. "Individuals respond differently to different therapeutics because there are substantial differences in the spectrum of genetic, biological and epigenetic characteristics betwe...
