Researchers appeal for new regulations to save coral reefs from live fish trade

... In particular, the health of the reefs is being compromised by the live reef fish trade, a serious threat that has prompted scientists to call for tighter regulations on the exploitation of reef resources which are particularly important to developing tropical nations. The scientists say there is now suffic...

World Trade Center identifications pushed forensic DNA technology

... them day in and day out nor had they been used on compromised samples.Eventually, forensic scientists used all three methods of DNA analysis on the 9/11 remains. A separate version of CODIS, WTC CODIS, unconnected to the FBI, was set up; a version of BEAST ?Bar Coded Evidence Analysis Statistics and Tracking ?...

How can we protect patients with weakened immune systems from influenza?

...tter ways to protect them. Because patients with compromised immune systems may be contagious longer than people with healthier immune systems, they may be a reservoir for the disease. In addition to the yearly toll of ordinary influenza (as many as 36,000 annual fatalities in the U.S.), added concerns over po...

Removing DNA repair gene causes metabolic syndrome

...nd kidney disease. "So if there are catalytically compromised forms of NEIL1 within the U.S. population, these people will be predicted to be at increased risk for developing the metabolic syndrome," a disease believed to affect more than 40 million Americans, said R. Stephen Lloyd, Ph.D., senior scientist at O...

Screening blood for West Nile virus

.... Given an increasing number of people living with compromised immune systems (recipients of organ transplants, patients with HIV/AIDS, and others), the idea of creating a 'supersafe' pool of blood products that is reserved for people who are less able to fight off infections contracted through contaminated bloo...

Wisconsin scientists discover a master key to microbes' pathogenic lifestyles

... by the fungi can be especially serious for immune compromised individuals, and some human populations seem to be more at risk for acquiring the infections. For example, U.S. soldiers who train in the American Southwest tend to be susceptible to coccidiomycosis because the organism that causes it is endemic to t...

Greasing interferon's gears may pave way to greater therapeutic benefits, fewer side effects

..., including children with asthma, heart disease or compromised immune systems." It may be possible, as well, to screen patients for levels of Stat1 responsiveness and use the same treatment strategy to correct low levels of response, according to Holtzman. The researchers are currently screening newborn infant...

'Sharp' older brains are not the same as younger brains

.... The team found that while the older rats with compromised cognition had brains that had lost the ability to adjust the force of those synaptic communications, the older rats whose memories remained sharp still had that capacity. Interestingly enough, the successful older rats also relied far less than did y...

Plant defenses prompt bacterial countermeasure in the form of 'island' DNA excision

...that have excised the genomic island do not appear compromised in their ability to grow and cause disease within the host bean plant. These findings offer a molecular explanation for how exposure to plant resistance mechanisms can directly drive the evolution of new virulent forms of a bacterial pathogen. ...

HIV drug resistance increasing in UK and among highest in the world

... drugs (combination antiretroviral therapy) may be compromised because of this. Using national data on HIV positive cases, the researchers tested patients for resistance to the antiretroviral drugs before embarking on the treatment. Tests were conducted on 2,357 patients between 1996 and 2003 ?thus researchers ...

Grabbing addiction by the tail

... In addicted rats, cell-to-cell communication is compromised as a result of certain long-term changes at the level of individual neurons. Their research has produced a targeted drug that tricks brain cells into preventing those changes. "We think this is a good candidate for a drug against addiction that has v...

Proposal would allow wild animals to roam North America

...n, would help revitalize ecosystems that have been compromised by the extinction of many of the continent's large mammals, many of them predators. It would also offer ecotourism and land-management jobs to help the struggling economies in rural areas of the Great Plains and Southwest. During the Pleistocene era ...

Insulin pulses keep the liver lean

...endent inhibition of fatty acid synthesis might be compromised as a consequence or even a cause of the insulin-resistant state," wrote Alan Saltiel of the University of Michigan in an accompanying preview. In this case, he added, finding ways to mimic the effects of CEACAM1 might help to alleviate chronically el...

Invitrogen Launches i-Path -- A Unique Systems Biology Platform at BIO 2005

...use it is well known that embryonic development is compromised when in vitro matured oocytes are used, and in cloning technology the oocytes undergo intensive micromanipulation, which makes it even harder to develop good quality blastocysts. Once we have achieved this, the next step will be the isolation of the ...
