First-ever Compounds To Target Only Metastatic Cells Are Highly Effective Against Breast, Prostate, And Colon Cancers

...hers." If compounds could be found that slowed or halted cancer spread, doctors could gain valuable time in shrinking the primary tumor. "If we had the luxury of time, we could treat that primary tumor at lower doses, too, with fewer side effects for the patient," Dr. Huang said. Until now, agents that sp...

Elusive salamanders have role in developing new sampling models

...e of a 100-year drought event that dried ponds and halted reproduction from 1999 through 2002. Since the first salamander was found six weeks ago, 36 more have been found in one pond, but none in 11 others that have supported them in the past. In the United States, flatwoods salamanders are found only in F...

New study finds how cells with damaged DNA alert the immune system

...hen genetic abnormalities occur, the cell cycle is halted so that the cell has time to fix the damage before the DNA is replicated. If the damage is too severe for the cell to repair on its own, it can trigger cell death, a process known as apoptosis. "All of this is happening autonomously within the cell,...

Chernobyl: The true scale of the accident

...tares taken from production. Timber production was halted in 694,200 hectares of forest. Remediation made "clean food" production possible in many areas but led to higher costs in the form of fertilizers, additives and special cultivation processes.

Kenya halts first field trials of GM maize

...aize growing in open field trials. The government halted the research and ordered the destruction after discovering that a technician had sprayed a restricted pesticide on maize modified to resist attack by insects called stem borers.

DNA gene vaccine protects against harmful protein of Alzheimer's disease

...ed into muscle, Dr. Rosenberg said. That study was halted when a small percentage of participants developed inflammation of the brain and spinal cord. Injecting the gene, in contrast, caused no brain inflammation in the mice. Dr. Rosenberg said the difference was partly because in the human trial, the pro...

International HIV/AIDS trial finds continuous antiretroviral therapy superior to episodic therapy

...DSMB recommended that enrollment into the trial be halted in light of the findings to date, and the SMART Executive Committee and NIAID agreed with the recommendation. Upon reviewing the results, the Executive Committee also conveyed to local study investigators its recommendation that it would be prudent t...

In the remaining cases, however, the pulses converted the single wave into multiple waves that continued to activate the cardiac cells at an accelerated rate. "In other words, instead of terminating it...

Buildup of damaged DNA in cells drives aging

...DNA damage somehow triggered hormonal changes that halted growth, while also boosting maintenance and repair. Because growth hormone levels go down as we get older, contributing to loss of muscle mass and bone density, the investigators systematically compared the gene expression pattern of their progero...

At this time, infected cattle remained in their herds and the researchers suggest that this allowed them to transmit the disease to other cattle and to badgers. "Our findings helps to...
