New study suggests that e-cigarette vapors can damage lungs

Do electronic cigarettes help people quit smoking? As the debate continues on that point, a new University of Rochester study suggests that e-cigarettes are likely a toxic replacement for tobacco products.

Johns Hopkins researchers reveal that e-cigarettes weaken immune system

In a study with mice, Johns Hopkins Bloomberg School of Public Health researchers have found that e-cigarettes compromise the immune system in the lungs and generate some of the same potentially dangerous chemicals found in traditional nicotine cigarettes.

Research shows olfactory proxy detection is a phenomenon in both insects and humans

Antioxidants are natural food ingredients that protect cells from harmful influences. Their main task is to neutralize so-called "free radicals" which are produced in the process of oxidation and which are responsible for cell degeneration.

Lung cancer rates are lower in higher-elevation counties, new study finds

Here's another potential reason to live up in the mountains. Lung cancer rates in both smokers and non-smokers are lower in higher-elevation counties in the western part of the United States, suggesting that oxygen may promote the incidence of lung cancer, according to a new study co-authored by a student at the Perelman School of Medicine at the University of Pennsylvania.

Atmospheric oxygen may play role in lung carcinogenesis, new study suggests

The ancient physician/alchemist, Paracelsus, said: "The dose makes the poison." According to a new study published in PeerJ, even oxygen may fall prey to the above adage. While essential to human life, aspects of oxygen metabolism may promote cancer. Capitalizing on the inverse relationship of oxygen concentration with elevation, researchers found lower rates of lung cancer at higher elevations, a trend that did not extend to non-respiratory cancers, suggesting that carcinogen exposure occurs via inhalation.

New insight into molecular mechanism of ancient evolutionary enzyme

A team led by structural biologists at The Scripps Research Institute has taken a big step toward understanding the intricate molecular mechanism of a metabolic enzyme produced in most forms of life on Earth.

Researchers examining new antioxidant-based therapeutic approaches to hypertension

High blood pressure affects more than 70 million Americans and is a major risk factor for stroke, heart failure and other renal and cardiovascular diseases. Two University of Houston College of Pharmacy researchers are examining the role of intrinsic antioxidant pathways in mitigating hypertension.

Simple supplement could reduce heart disease in individuals born with low birth weight

A simple supplement could be a safe and cost-effective way of reducing heart disease in individuals born with a low birth weight, suggests research from the University of Cambridge. The study, carried out in rats, also raises the possibility of developing a blood test to indicate how much damage there is in the aortas of these individuals.

New technique measures antioxidant capacities of citrus juices

The antioxidant activity of citrus juices and other foods is undervalued. A new technique developed by researchers from the University of Granada for measuring this property generates values that are ten times higher than those indicated by current analysis methods. The results suggest that tables on the antioxidant capacities of food products that dieticians and health authorities use must be revised.

Proper copper levels essential to health of the brain at rest, new study finds

In recent years it has been established that copper plays an essential role in the health of the human brain. Improper copper oxidation has been linked to several neurological disorders including Alzheimer's, Parkinson's, Menkes' and Wilson's.

Blocking key brain receptor cell could neutralize biological consequences of Alzheimer's

Blocking a key receptor in brain cells that is used by oxygen free radicals could play a major role in neutralizing the biological consequences of Alzheimer's disease, according to researchers at Temple University.

University at Buffalo researchers receive $500,000 grant to study IED-induced vision loss

It's well known that battlefield explosions can cause hearing loss, but veterans may be surprised to learn that their vision may also suffer — sometimes weeks or months after combat exposure.

Sulindac drug can protect against oxidative damage due to AMD

While oxygen is essential to our planet's life force and the way we function and stay healthy, high concentrations referred to as oxidative stress may very well be the cause of more than 70 widely-spread diseases such as cancer, heart disease, neurodegenerative diseases, and eye diseases including macular degeneration.

UCLA study: Asthma harms more than just the lungs, may be more harmful than previously thought

Asthma may be more harmful than was previously thought, according to UCLA researchers who found that genetic damage is present in circulating, or peripheral, blood. Doctors previously thought that the genetic damage it caused was limited to the lungs.

Cornell University chemists uncover new insight into the underlying causes of ALS

Using a technique that illuminates subtle changes in individual proteins, chemistry researchers at Cornell University have uncovered new insight into the underlying causes of Amyotrophic Lateral Sclerosis (ALS).

Study can help breeders improve health-related traits in cultivated tomatoes

Tomatoes are known to be rich in antioxidants such as vitamin C, lycopene, β-carotene, and phenolics. Antioxidants, substances capable of delaying or inhibiting oxidation processes caused by free radicals, are of interest to consumers for their health-related contributions, and to plant breeders for their ability to provide plants with natural resistance to biotic and abiotic stresses.

Chronic consumption of melatonine helps combat obesity, diabetes

Scientists at the University of Granada, in collaboration with La Paz University Hospital in Madrid and the University of Texas, San Antonio in the US have demonstrated through several experiments conducted on Zucker obese rats that chronic consumption of melatonine helps combat obesity and diabetes mellitus type two.

New UCLA study finds that oxidized lipids may also contribute to pulmonary hypertension

Oxidized lipids are known to play a key role in inflaming blood vessels and hardening arteries, which causes diseases like atherosclerosis. A new study at UCLA demonstrates that they may also contribute to pulmonary hypertension, a serious lung disease that narrows the small blood vessels in the lungs.
