Novel therapy combinations gain ground in treating hepatitis
...he toxic byproducts of acetaminophen liver damage, created
when a chemical (in this case, acetaminophen) binds to proteins in the liver that are then released into the blood when cells die. As a positive control group, the team also included 10 documented cases of acute liver failure (ALF) resulting directl...
The vicious cycle of rainforest destruction
...ese measurements, detailed computer models will be created
to look at the impact of changes in tropical vegetation on the Earth system in terms of carbon emissions, temperature and rainfall. These changes will then be fed back into the models to determine their cumulative impact and ultimately predict global...
Chromosomal abnormalities in sperm higher after vasectomy reversal
...structive azoospermia, a condition where sperm are created
but cannot be mixed with the ejaculatory fluid due to a physical obstruction (such as a vasectomy). He found that they had high rates of chromosomal aneuploidy (where an abnormal number of specific chromosomes or chromosome sets exist within the nu...
Brazil creates buffer zone around coral reefs off Atlantic coast
The Brazilian government has created

by Brazil's Institute of Environment and Natural Resources (IBAMA), encompasses nearly 95,000 square...
Buckyballs boost antibody's chemotherapy payload
...body called ZME-018. Antibodies are large proteins created
by the immune system to target and attack diseased or invading cells. Previous work at M. D. Anderson has shown that ZME-018 can be used to deliver drugs directly into melanoma tumors, and work at Rice has shown that Taxol can be chemically attached...
UCLA scientists strengthen case for life more than 3.8 billion years ago
...owing the geology of the area, Manning said. So he created
one. "I wandered around that outcrop for two-and-a-half weeks--it's not a big area--with a clipboard, maps, a compass and grid paper. We mapped it like an archeologist would map it," Manning said. "It became clear that these rocks that hosted life l...
Ever-happy mice may hold key to new treatment of depression
...ce without the TREK-1 gene ('knock-out' mice) were created
and bred in collaboration with Dr. Michel Lazdunski, co-author of the research, in his laboratory at the University of Nice, France. "These 'knock-out' mice were then tested using separate behavioral, electrophysiological and biochemical measures kno...
NASA technology helping injured US troops
... Center in Greenbelt, Md. The late James Kerley created
and patented the technology, consisting of short segments of flexible cable that connect to hardware, all of which allows joint-like, multidirectional movement and shock absorption. Allen Crane and Wayne Eklund teamed with Kerley in the 1990s to inco...

Adult stem cells are touchy-feely, need environmental clues
...e our muscles, are based on the mechanical tension created
by molecules of actin and myosin," Engler said. "When we deprive these stem cells of myosin, the cells do not respond to their physical environment, only their chemical environment." But, the physical microenvironment can change due to injury and...
Toxic molecule may cause most common type of muscular dystrophy
...In their latest research, Mahadevan and colleagues created
a new type of mouse model with many extra copies of the CTG repeats, each attached to DNA for a protein that glows green under a microscope. They also integrated an "on switch" for MMD in the mice, activated by giving them doxycycline, an antibiotic...
Genes discovered that allow gum disease bacterium to invade arteries
...e four different genes play in this ability. They created
four strains of the bacterium, each with a different gene mutated to disable it, and tested their ability to invade and survived in artery cells compared to a fully functioning strain of P. gingivalis. "Our study showed that all four mutated strai...
Radioactive scorpion venom for fighting cancer
...smolecular Corporation in Cambridge, Massachusetts created
a radioactive version of this scorpion venom. Called TM-601, it contains an artificial version of the venom protein, attached to a radioactive substance called iodine-131 (I-131). When it enters the bloodstream, the compound attaches to the glioma c...
Purdue creates new low-cost system to detect bacteria

in 1934 by Dutch physicist Fritz Zernike, who created
a set of mathematical "descriptors" subsequently called radial Zernike polynomials. These descriptor...
Tiny shock absorbers help bacteria stick around inside the body

by the body in response to infection by one serotype are high enough to protect against infection by related serotypes. After this period, however, antibody levels drop to levels that are no longer neutralizing but instead are exploited by the dengue...
