Taking Aim With Nanoparticle PEBBLEs

...that thwarts many chemotherapy drugs. "The really bad cancer cells get immune to chemotherapy drugs ?they pump the drugs back out," Kopelman said. Cancer cells can't do that to PEBBLEs, though, because PEBBLEs are already on the outside. Another advantage: the "killer oxygen" that PEBBLEs deliver to can...

UF Researchers Map Bacterial Proteins That Cause Tooth Loss

...ugar levels in people with diabetes. If that’s not bad enough, pregnant women with periodontal disease are seven times more likely to deliver low-birth-weight, preterm babies. Proteins are important to study because they are the foundation of the cellular structure of every living organism, Lamont said. ...

US life expectancy about to decline, researchers say

...Social Security does not appear to be in nearly as bad a shape as we think," Olshansky said. "The obese may be inadvertently 'saving' Social Security, but the obese themselves and the health care system that cares for them will pay a very heavy price in terms of higher death rates and escalating health ...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

... alarm: There simply aren’t enough drugs to combat bad bugs. Bacteria are increasingly adept at outwitting the traditional antibiotic arsenal. Yet designing and testing new antibiotics can be a maddeningly slow and costly process ?if pharmaceutical companies even bother, says Hartmut Derendorf, chairman...

...estruction of DNA." However, too much NO can be a bad thing. Sustained overproduction of NO can cause septic shock (sepsis). "In sepsis, which is a systemic bacterial infection, the body expresses iNOS which generates relatively high concentrations of NO," says Dr. Hobbs. "This aids host defense by kill...

During the next seven years, the Drug-Induced Liver Injury Network, or DILIN, will study patients who have suffered severe liver injury caused by prescription and over-the-counter medications, nutritional supplements, alternative medi...

Grasping metaphors: UC San Diego research ties brain area to figures of speech

...e you might get robbed. The patients were equally bad at matching a bulbous, amoeboid shape to the sound "booba" and a jagged shape to "kiki."

Bugs, even 'bad' ones, can be educationally beneficial, new book says

We have much to learn from bad bugs, according to Gilbert Waldbauer, whose book "...st colleagues to illustrate what we can learn from bad bugs. Many of the pests he describes are found in Illinois, including the corn rootworm. Other regi...

Researchers pioneer new gene therapy technique using natural repair process

...o 7 percent of cells had traded both copies of the bad gene for the correct version. With the correct IL-2R gene in place, levels of the IL-2R protein also were restored. The change to the cells seems permanent, Dr. Porteus said, and the correct gene is easily maintained after many cell divisions. "Th...

Conversely, wolves have relatively light, sleek bodies and big, wide paws that act like snowshoes. In the Canadian Rockies, wolv...

Two studies document rise of superbugs in the environment

Researchers at the Beth Israel Deaconess Medical Center and Harvard Medical School studied the prevalence of bacteria resistant to three or more drugs over a six-year period. From 1998 to 2...

Mosaic mouse technique offers a powerful new tool to study diseases and genetics
