Genome project finds the 'triggers' for E. coli illness
...ability for large-scale genetic change may make it harder to control the public health threat. This strain of E. coli O157:H7 causes an estimated 75,000 illnesses a year in the United States, including numerous deaths, and is especially dangerous to vulnerable populations such as children, the elderly and ...Teenagers tend to have a harder time functioning in the morning than their parents do. Long flights can cause jet lag. Both phenomena are related to "biological clocks," molecular mechanisms that regulate how humans and other organisms sleep, wake and function throughout a 24-hour ...New technique will improve delivery of drugs and gene therapy for cystic fibrosis patients

...This puts a strain on the heart, which has to work harder to move adequate amounts of blood through the lungs to enable the person to breathe properly. Heart-lung transplants may be the only hope for some patients. It is twice as common in women as it is in men and tends to develop in people in their 20s an...Gene found to contribute to deadly form of breast cancer
... its speed and ability to metastasize make it much harder to treat. Only 45 percent of women with the disease are alive and disease free after five years and optimal treatment.

The satellite would sit in ......veteran anglers complained that fish were becoming harder to catch. "They said the fish were getting a bit too smart," says Hayes.

Once enough blood vessels are blocked off, blood flow is inadequate. Most of the symptoms of this disease are related to poor blood flow.

The disease affects twice as many women as men -- usually women of child-bearing age -- although it can occur at any age, including infancy.
