Researchers have found that butyltins can disrupt the function of human natural killer cells, which are critical in fighting tumor cells and infected cells. The study's findings highlight the need for further research into the potential health effects of these chemical contaminants on humans.
The American Heart Association reports that high dietary salt intake is linked to increased risk of heart disease and stroke in overweight individuals. Snoring may also be a warning sign for cardiovascular disease, as it activates the sympathetic nervous system. Additionally, controlling weight through exercise can reduce cardiovascula...
A study found that patients who experience strokes during the night wait four to seven hours longer for emergency treatment than those whose strokes occur during the day. This delay is caused by the difficulty in determining the exact time of stroke onset when symptoms are only apparent after waking up.
Recent experiments by physicists at the University of Notre Dame and Tohoku University have found that current theories describing turbulence may need modifications, particularly in extreme situations. The findings suggest that ultra-hard turbulence, a predicted state of turbulent flow, may not exist as previously thought.
A new study from Boston University suggests that moderate alcohol consumption up to 20 grams/day may not raise PAI-1 levels; instead, higher levels are associated with a modest increase. The findings suggest that moderate drinking may have beneficial effects on PAI-1 or at least no harm.
The American Heart Association recommends statin drugs as a second step after lifestyle modifications for cholesterol-lowering. Red yeast rice, found in Cholestin, may be less safe and effective than prescription medications.
Researchers at CalTech designed a new protein-like polymer that supports endothelial cell growth and could be used for blood vessel replacement. The material is expected to aid patients who cannot supply their own replacement veins, offering a potentially improved success rate compared to current synthetic polymers.
Scientists warn that Arctic climate change could counteract ozone layer recovery efforts. Particle sedimentation processes in the stratosphere may remove protective gases, hindering the healing of the ozone layer over the northern polar region.
A new instrument helps children understand the difference between truth and lies, and recognize the importance of telling the whole truth. The Lyon-Saywitz Oath-Taking Competency Picture Task has shown that children as young as five can be trusted to understand what they're promising in a court of law.
A Chinese condiment extract, Cholestin, has been shown to reduce total blood cholesterol by nearly 26% in elderly patients and 'bad' cholesterol by 32.8%. The supplement contains HMG-CoA reductase inhibitors that inhibit liver-produced cholesterol production.
Research presents evidence that moderate caffeine consumption can improve performance in tasks requiring sustained attention. Additionally, studies suggest that green tea catechins have anti-oxidative, antibacterial, and antiviral potency, while polyphenolic compounds in cocoa may also have cardiovascular benefits.
Researchers at the University of Pittsburgh have found that electron beam computed tomography (EBCT) can identify older adults with heart disease who appear healthy through standard non-invasive tests. EBCT measures coronary and aortic calcification, which are known risk factors for coronary events.
A NASA study led by Dr. Dale Quattrochi found that Atlanta's urban expansion creates a unique heat island effect, influencing local weather patterns and air quality. The study revealed that this phenomenon can lead to increased ozone production and thunderstorms due to the interaction between warm air and surrounding areas.
Researchers at Cornell University are working on an artificial gel made of silicon that could lead to faster and cheaper methods for DNA sequencing. The biochip is designed to identify DNA fragments by measuring their movement through uniform-sized passages, allowing for more precise control and comparison with theoretical predictions.
New studies suggest ecosystems can be disrupted by small environmental changes or loss of minor species, challenging conventional wisdom on ecological protection. Research finds importance of both keystone and lesser species in ecosystem function.
A study found that low educational level increases the risk of congestive heart failure by 35% compared to those with more education. The strongest risk factors for developing CHF were diabetes, high blood pressure, overweight, smoking, and physical inactivity.
Astronomers have detected the brightest optical celestial object ever recorded using a low-cost, automated telescope built from recycled lenses and hardware. The ROTSE-1 telescope captured optical emissions from a gamma ray burst while it was still arriving, providing new insights into the phenomenon.
