Manual dishwashing study digs up dirt on dish cleanliness

...ore the food dries. It saves washing time and gets rid of places where bacteria can survive drying and washing." ...

MIT device draws cells close -- but not too close -- together

... it. "If you can get away with it, you want to get rid of the supporting cells," she says. This simple device will also be useful for exploring a host of other cellular interactions. Most prominently, the device could be very useful in exploring embryonic development, during which the local cellular e...

Microbes compete with animals for food by making it stink

...t we can say the effect is chemical because we got rid of the nutrient and texture aspects of the bait and determined that it's something in this fraction of the bait's chemistry," Hay said. "It's either a complex mix of chemicals or perhaps something we destroyed during our lab test processes or maybe a...

Why don't all moles progress to melanoma?

...This slows the protein production process and gets rid of excess incoming amino acids, giving the ER a chance to catch up. If that doesn't work, the UPR causes the cell to destroy itself in a process called apoptosis. "Traditionally, the ER's role was considered to be limited to protein folding or prot...

Researchers develop technologies to devour food pathogens

...volve washing and scrubbing, and cannot completely rid a product of a pathogen like E. coli, said Richard Linton, a professor of food science. "We can use the laser technology to detect problems more quickly, determine exactly what the pathogen is and where it came from," Linton said. "As for using thi...

Researchers in Montréal and the US create model of key immune-system component

...rch findings, applied to the body's ability to get rid of infections, will help develop new treatments and approaches for the prevention of diseases such as tuberculosis." ...

Cell death following blood 'reflow' injury tracked to natural toxin

...ngineered to lack an enzyme that chews up and gets rid of PAR. These mouse brains contained twice as much PAR-polymer as those of normal mice. After the researchers induced a blood clot injury like a stroke, the same mice showed a 62 percent increase in the area of brain damage compared to normal litt...

Parasitic plants sniff out hosts

...plant. "There is currently no reliable way to get rid of these pests," says Justin B. Runyon, graduate student in entomology. "It is estimated that in California each year, a 20 percent infestation of the tomato crop reduces yield by 25 percent and causes a loss of 4 million dollars." The researcher...

Tastes great! Study shows brain's response to pleasing -- and changing -- tastes

...on of diet and hormones that cause the body to get rid of salt, the picture changed. Suddenly, the rats' brain activity rose as high when they received the salt water as it had when they received sugar water. The effect lasted for a while after the rats' bodies returned to normal salt levels, but soon en...

Study identifies substances in grapefruit juice that interact dangerously with some drugs

...furanocoumarins from grapefruit juice entirely got rid of this interaction," Watkins said. In this randomized study, 18 healthy volunteers took 10 milligrams of felodipine with each of three juices: orange juice, regular grapefruit juice, and grapefruit juice devoid of furanocoumarins. Blood was collect...

University of Minnesota researchers take new look at cellular suicide

...ing damaged cells but shaping an embryo by getting rid of webbing tissue between fingers and toes. By contributing to the understanding of how apoptosis works, the researchers, led by Zigang Dong of the university's Hormel Institute in Austin, Minn., hope someday to see the process used to kill cancer ce...

A new tool against brain disease

...ou could actually change the PD-1 level by getting rid of the viral antigen with drugs," said Walker. An antigen is a protein on a virus or other infectious agent that triggers an immune reaction. Walker said one of the team's key findings emerged from their test tube studies showing that blocking ...

Toxic molecule may cause most common type of muscular dystrophy

... System have shown for the first time that getting rid of poisonous RNA (ribonucleic acid) in muscle cells can reverse myotonic dystrophy, the most common type of muscular dystrophy in adults. About 40,000 people in the United States have myotonic muscular dystrophy (MMD). The disease can cause a slow,...

Brain enzyme treatment relieves memory lapse in Alzheimer's mice

An enzyme that helps neurons rid themselves of excess or aberrant proteins is required for normal brain function, according to a new report in the August 25, 2006 issue of the journal Cell, published by Cell Press. What's more, by increasing brain levels of the enzyme in mice with A...

Chewing up a key regulator of fat synthesis keeps mice lean despite a high-fat diet

...cation of ACC, known as ubiquitination, which gets rid of the enzyme altogether. "In this parallel pathway, TRB3 serves as a go-between for an enzyme that marks ACC for degradation," says Jose Heredia, a graduate student in Montminy's lab. TRB3 levels in adipose tissue usually rise only during fasting,...

Johns Hopkins lab scientists tame overactive CF protein

...mutant CFTR. "We were able to confirm that to get rid of the defective CFTR protein, cells deploy VCP/p97 protein, which latches onto the damaged CFTR and sends it to the proteasome for destruction," Zeitlin says. "Using RNA interference, which basically works by silencing the expression of genes or pro...

Study shows hope for ridding lakes of clawed invader

... to the point where it may actually be possible to rid lakes of an animal that has vexed scientists, anglers and conservation agencies alike for decades. "They pretty much wipe out all of the rooted aquatic plants, they eat fish eggs, they either eat or compete with native invertebrates and, in general...

APS lecturer shows rare video of 'teacher-student' immune cell interactions in live animal

...rns to recognize the antigen, but that doesn't get rid of the microbe that has entered the body," von Andrian said. He traced the path of the educated T cells leaving the lymph node, when they become known as effector cells. In addition, von Andrian addressed how these T cells kill those cells they ident...

Stem cell transplants improve recovery in animal models for stroke, cerebral palsy

...hes, including transplantation and tPA, cannot get rid of that ischemic core," Dr. Borlongan said. "But outside of that core there is a lining, what we call the penumbra, and that penumbra, if you do not treat it over time, becomes part of the core. We are showing, that even one week after a stroke, we a...
