Can engineered immune cells stop AIDS?

Twenty years after its introduction, gene therapy still holds great promise as a way to harness the insidious power of viruses such as human immunodeficiency syndrome (HIV). But scientists have yet to solve a vexing problem: developing an efficient transport system that is capable of delivering the...

New study aims to stop sepsis in its tracks

If you've had a heart attack or stroke, paramedics, doctors, and nurses follow standardized protocols for what to do right away, and their efforts improve your odds for a full recovery. That's not the case if you have a body-wide infection known as sepsis, which can be fatal within a few hours and ...

For crickets, parasitic flies can stop the music

Love hurts ?really bad, for some unlucky crickets, anyway. Male crickets draw not only females with their songs but also parasitic flies. The uninvited guests then deposit larvae that burrow into their amorous hosts, grow for about a week and then tear their way out in "Alien" fashion, killing th...

Two-faced protein can stop metastasis or promote it, researchers say

A protein known to be a key component of the glue that holds cells together also is involved in breaking them apart and promoting their movement when tumors begin to spread to other parts of the body, researchers at Mayo Clinic have found. The study, published in the Sept. 18 online issue of the ...

Brains can recover from alcoholic damage but patients should stop drinking as soon as possible

The findings, published today (18 December 2006) in the online edition of the journal Brain [1], used sophisticated scanning technology and computer software to measure how brain volume, form and function changed over six to seven weeks of abstinence from alcohol in 15 alcohol dependent patients (t...

Control measures fail to stop spread of new H5N1 virus

A new variant of the bird flu virus H5N1 emerged in late 2005 and replaced most of the previous variants across a large part of southern China, despite an ongoing program to vaccinate poultry, according to researchers at the University of Hong Kong in collaboration with scientists at St. Jude Child...

Statins stop hepatitis C virus from replicating

A new study shows that statins, which are typically used as anti-cholesterol medications, can inhibit the replication of the hepatitis C virus (HCV). They could replace ribavirin in combination therapy with interferon. These findings are published in the July 2006 issue of Hepatology, the official ...

Scientists stop autoimmune disease without shutting off immune system

Skin is our first line of defense against infection. But people with a rare, life-threatening autoimmune disease called pemphigus vulgaris lack that protection because their immune system attacks the proteins that hold skin cells together. They develop severe blisters and raw sores as the top layer...

Proteins stop blood-vessel and tumor growth in mice
