Researchers find exposure to air pollution increases severity of asthma symptoms

Exposure to dirty air is linked to decreased function of a gene that appears to increase the severity of asthma in children, according to a joint study by researchers at Stanford University and the University of California, Berkeley.

Study suggests H2O2 can act as anti-inflammatory compound

A major blow to the free radical theory of aging, which had lead the research in aging for more than 50 years and fuels a multimillionaire anti-aging industry has just been published by Portuguese scientists from the University of Minho. According to the theory, free radicals provoke oxidative damage and this is the cause of aging.

Children with eczema at greater risk of developing asthma and food allergies

Children with eczema, a chronic skin condition that often begins in childhood, have a greater risk of developing asthma and food allergies. The number of children with eczema is rising, but the reasons for this are unclear. A new study soon to be published in The Journal of Pediatrics examines the relationship between pet ownership and eczema. Researchers found that dog ownership among children with dog allergies may reduce the risk of developing eczema by age 4 years; cat ownership, however, may increase the risk among children with cat allergies.

Study reveals consistent correlation between adult diabetes and particulate air pollution

A national epidemiologic study finds a strong, consistent correlation between adult diabetes and particulate air pollution that persists after adjustment for other risk factors like obesity and ethnicity, report researchers from Children's Hospital Boston. The relationship was seen even at exposure levels below the current EPA safety limit.

Medical team uses LeadCare II blood-lead test to examine people exposed to lead poisoning in Nigeria

As part of the international response to the lead-poisoning crisis linked to small-scale gold-mining activities in this northwestern region of Nigeria, a medical crisis team is deploying Magellan's three-minute LeadCare II blood-lead test in the triage, assessment, and clinical follow-up of thousands of villagers who have been exposed to extremely high levels of lead in the soil and water.

Researchers find stress-activating factors can control genes

Stress has become one of the major disease states in the developed world. Researchers from Dr.Klaus Hansen's group at BRIC, University of Copenhagen, have just shown that external factors can stress our cells through the control of our genes. "We found that stress-activating factors can control our genes by turning on certain genes that were supposed to be silenced.

Progress in realizing potential of satellite measurements of air pollution

In many developing countries, the absence of surface-based air pollution sensors makes it difficult, and in some cases impossible, to get even a rough estimate of the abundance of a subcategory of airborne particles that epidemiologists suspect contributes to millions of premature deaths each year. The problematic particles, called fine particulate matter (PM2.5), are 2.5 micrometers or less in diameter, about a tenth the fraction of human hair. These small particles can get past the body's normal defenses and penetrate deep into the lungs.

Asbestos found in Queensland schools

Asbestos, known to be the cause of malignant mesothelioma, a rare and aggressive cancer for which there currently is no cure, is still found in the playground of Tewantin State School in Tewantin, Queensland, Australia. Since the beginning of 2009 asbestos has been reported numerous times at the school. Repeated exposures to the toxic material over 20 to 50 years may lead to this cancer.

ProtAffin presents impressive efficacy data for PA401 in COPD

ProtAffin AG, a biotechnology company developing a novel class of biopharmaceutical products that act by targeting cell-surface glycan structures, today presents compelling preclinical data in chronic obstructive pulmonary disease (COPD) for its lead product PA401 at the European Respiratory Society Congress in Barcelona, Spain. This conference is the largest gathering of scientists and clinicians in the respiratory community in the world. The Oral Presentation will be made in the session "Pre-clinical models of airways disease".

Pollution increases risk for sudden cardiac arrest

The fine particles of pollution that hang in the air can increase the risk for sudden cardiac arrest, according to a new study conducted by a team from Long Island Jewish (LIJ) Medical Center and The Feinstein Institute for Medical Research.

Clemson biochemist receives grants to study DNA repair pathways

A Clemson biochemist has received grants totaling $787,000 to study how cells repair damaged DNA, which can cause cancer and genetic illnesses. The U.S. Department of Defense (DoD) and the National Institutes of Health (NIH) awarded Weiguo Cao three-year funding to investigate two DNA repair pathways.

American Lung Association data shows improvement in health benefits

The American Lung Association in California released new data today showing significant public health benefits from pursuing a smart growth future for California. The American Lung Association data shows health benefits, including reduced asthma attacks and premature deaths linked to the Vision California "mixed growth" and "growing smart" scenarios in 2035 that include more compact, sustainable development patterns.

New book relates mercury in vaccines to autism

The U.S. government revealed last week that they will compensate a family millions of dollars for their daughter's injury related to her infant vaccines that contained mercury and the subsequent development of autism. Yet, the CDC continues to tell the public that there is no connection between vaccines and autism and that the mercury has been removed, although the flu shot recommended for all pregnant women, infants, and children continues to be preserved with mercury.

Cleaning products do not increase risk of breast cancer: Research

Results of a new US study published today have looked at whether cleaning products are linked to an increased risk of breast cancer. They appear to show that women who say they used such products in the past are more likely to have breast cancer. But Cancer Research UK said that the results do not prove a link between cleaning products and breast cancer, and that the findings may have been distorted as a result of patients' existing beliefs about the health risks of chemicals.

World Water Week: Urbanization, irrigation, global food security

"Global efforts to improve access to drinking water have been hampered by rapid urbanisation, with the proportion of people in urban areas with access actually declining, according to U.N. figures presented" at the World Water Week conference in Stockholm, Agence France-Presse reports.

World Water Week kicks off with a focus on pollution, quality

A group of over 2,500 leading water experts from 130 countries gathered in Stockholm on Sunday to kick off World Water Week, where they will focus on "increasing water pollution and dwindling water quality around the globe," Agence France-Presse reports (Larson, 9/5).

New study finds additional link between Light At Night and cancer

A new study from the Center for Interdisciplinary Chronobiological Research at the University of Haifa has found an additional link between Light At Night (LAN) and cancer. This research joins a series of earlier studies carried out at the University of Haifa that also established the correlation. "High power light bulbs contribute more to 'environmental light pollution', which the study has shown is a carcinogenic pollution," notes Prof. Abraham Haim, who headed the study.

Study links community violence with asthma hospitalizations, emergency department visits

Patients with asthma who are exposed to violence in their community are at an increased risk for an asthma-related hospitalization and emergency room visits for asthma or any cause, according to new research from the University Of Pennsylvania School of Medicine. Exposure to community violence has been linked to more symptoms in pediatric asthma patients; however the new research adds to this finding with a longitudinal study showing a connection in an adult population and more than symptoms - actual emergency department visits and hospitalizations.
