Recent breakthroughs in common adult leukemia highlighted in New England Journal of Medicine

...ears after diagnosis. Since the disease most often strikes older adults, the patients whose disease follows this course usually die with the disease, not because of it. CLL may also follow a more aggressive course. In these cases, patients do require chemotherapy and have a lifespan of only about six to eigh...

Novel gene-silencing nanoparticles shown to inhibit Ewing's sarcoma

...a rare and often deadly bone cancer that generally strikes young adults. Despite aggressive therapy, about 40 percent of patients with Ewing's family tumors and 95 percent with metastases die as a result of their disease. Scientists now recognize that Ewing's sarcoma results when two chromosomes break and t...

Study reveals dramatic difference between breast cancers in US and Africa

Atmosphere may cleanse itself better than previously thought

... clouds absorb them and rain them out, or sunlight strikes them and the energy breaks the molecules apart. "The third way is the one we are concerned with here, the way that involves breaking these hydrocarbons down chemically," Francisco said. "For that, the atmosphere relies on a reactive group of chemica...

Survey reveals women and doctors aren't talking about HPV

...ed. About HPV and Cervical Cancer Cervical cancer strikes nearly 11,000 women in the United States each year, and is second only to breast cancer in the number of women it affects worldwide. Cervical cancer is caused by high-risk forms of HPV, which are transmitted sexually. In the majority of women, the vi...

Immune system's distress signal tells bacteria when to strike back

...could signal the bug," said Alverdy, "then the bug strikes back and then the inflammation process snowballs." Because the bacteria in this case are "normal flora," people with no real infection develop a chronic disease. The battles between pathogens and their hosts have been going on for millions of years,...

Could better mangrove habitats have spared lives in the 2004 tsunami?

...uch severe damage can be avoided if a tsunami ever strikes again. In an essay published this week in the June 21 issue of Current Biology, a group of researchers recount the first findings arising from their recent assessment of how mangrove ecosystems might have influenced the tsunami's impacts on coastal c...

Fragment of yellow fever virus may hold key to safer vaccine

... fever is the original viral hemorrhagic fever. It strikes more than 200,000 people a year, mostly in Africa, killing about 30,000 of them, the World Health Organization estimates. No drug treatment is effective against the virus. Since yellow fever is spread by mosquitoes, much of America has been safe fro...

Beauty queens urge girls not to sacrifice their bones

At a related media seminar, IOF released a new publication "Move it or Lose it" which looks at the impact of weight-bearing exercise on b...

Sleeping beauty plays a significant role in identifying cancer genes

...ransposon system to study lymphomas, a cancer that strikes the immune system. "Although our discovery was made in laboratory mice," said Jenkins, "we believe that the technology used will reveal new insights into human cancer and could be translated for clinical use. Hopefully, this discovery will speed up ...

Two designer drugs hit same lung cancer target, but only one is effective

... effect on the mutant signal, evidently because it strikes at a different part of the EGFR molecule. Reporting in the Aug. 17 issue of the Journal of the National Cancer Institute, the researchers say that the divergent results add to growing evidence that mutations in the targets of designer drugs critical...

Scientists get first glimpse at how plants, most animals repair UV-damaged DNA

...ge and repair processes this way: When a UV photon strikes a portion of DNA, the atoms in the DNA molecule become excited. Sometimes an accidental bond forms between them. The bond is called a photo-lesion, and can lead to a kind of molecular injury called a dimer. Dimers prevent DNA from replicating properl...

UF study first to quantify validity of DNA I.D. tool using marine snails

...e engine, he said. "Engines are built to withstand strikes by birds up to a certain size, but not a large crane or goose," he said. "Thus, it's helpful to know which brand of shredded tweet went through the combine." And because the technology also can identify eggs or other different life stages it could b...

Gene therapy works in mice to prevent blindness that strikes boys

Writing in the August issue of Molecular Therapy, scientists from the UF Genetics Institute describe how they successfully used gene therapy in mice to treat retinoschisis, a rare genetic disorder that is passed from mothers, who retain their ...

Customized gene chip provides rapid detection of genetic changes in children's cancer

...most common cancer found in infants, neuroblastoma strikes the peripheral nervous system, often appearing as a solid tumor in a child's chest or abdomen. Some types of neuroblastoma are low risk, resolving after surgeons remove the tumor, while others are much more aggressive. Identifying the correct risk le...

The Texas students, including Tabor and Aaron Chevalier, realized that after optimizing the pigments and agar growth media, these b...
