Too much water may be as dangerous as too little during long-distance athletic events

...ir sodium concentrations were very low - some were dangerously low," Dr. Levine said. "The recommendations listed in the study that fluid-replacement schedules be individualized for all athletes competing in long-distance events should be taken seriously by all competitors." People lose water and salts from the...

Gene therapy to lower blood pressure just enough

...wever, this kind of gene reduced blood pressure to dangerously low levels, said O'Malley. Obviously, a method of controlling the gene and the amount of ANP a cell makes was needed. The special viral vector developed by O'Malley and his colleagues combines a special kind of adenovirus altered so it does not prod...

Bare metal stents deliver gene therapy to heart vessels with less inflammation in animal studies

...ay gradually form within the stents themselves and dangerously narrow the passageway. A newer generation of stents releases drugs to counteract this renarrowing process, called restenosis, but the polymer coatings that initially hold the drugs to the stents may stimulate inflammation. The inflammation in turn le...

Study supports 'urgent' need for worldwide ban on lead-based paint

...sia -- still produce and sell consumer paints with dangerously high lead levels. The report appears in the early online edition of the journal Environmental Research, to be published in September 2006. The researchers say that this lead-based paint production poses a global health threat, and a worldwide ba...

All the eggs in one basket

...ercent of the remaining sites have been reduced to dangerously low populations. "The loss of even a single nesting site makes a permanent, irreversible dent in the sea turtle population," says McClenachan. The scientists estimate that today's current population of 300,000 turtles once was as large as 6.5 mil...

Molecular 'on/off switch' controls immune defenses against viruses

...es when the immune system's response to a virus is dangerously overactive, which happened in many flu cases during the 1918 pandemic. "Fine-tuning immune response to infection is where antiviral or immune regulatory drugs are headed," said Dr. Gale....

Lead-'scrubbing' drug may also improve muscle function in lead-exposed children

... researchers say a therapy commonly used to remove dangerously high levels of lead from the body may also improve muscle functions associated with postural balance and movement in lead-exposed children. Led by Amit Bhattacharya, PhD, the UC team found that children treated with succimer (SUX-sim-er) chelation ...

Antibody signal may redirect inflammation to fuel cancer

...ibody receptors can also be activated to turn on a dangerously different program: inducing leukocytes to boost cell growth, increase the number of blood vessels and "remodel" tissue in the area -- all of which help cancer develop. The finding adds a critical and surprising detail to the emerging view that inf...

Runners -- Let thirst be your guide

... water will be retained, and that excess water can dangerously dilute the level of sodium in the blood that is needed for organs to function, he adds. Investigators have been researching the triggers that stimulate AVP secretion during exercise, and have found several. One is a loss of fluid from the body and...

Use of the compound not only appears to prevent the development of these diseases, but also to reverse the symptoms of these illnesses in mice.
