What can country of birth tell us about childhood asthma?

BOSTON (October 25, 2010) — Researchers from Tufts University pooled data from five previous epidemiological studies to investigate the prevalence of asthma in children in the Boston neighborhoods of Chinatown and Dorchester. Among children born in the United States, low socioeconomic status (SES) and exposure to pests (mice and cockroaches) were both associated with having asthma. Neither association was present in children born outside of the United States. The study was published online in advance of print in the Journal of Immigrant and Minority Health.

Beauty from the bottom up

Flamingos apply natural make-up to their feathers to stand out and attract mates, according to a new study by Juan Amat, from the Estación Biológica de Doňana in Seville, Spain, and colleagues. Their research is the first to demonstrate that birds transfer the color pigments (carotenoids) from the secretions of their uropygial gland for cosmetic reasons. The uropygial or preen gland is found in the majority of birds and is situated near the base of the tail. The study is published online in Behavioral Ecology and Sociobiology, a Springer journal.

Plant stem cells could be fruitful source of low-cost cancer drug

A popular cancer drug could be produced cheaply and sustainably using stem cells derived from trees, a study suggests.

Researchers have isolated and grown stem cells from a yew tree whose bark is a natural source of the anticancer compound paclitaxel. The development could enable the compound to be produced on a commercial scale at low cost, with no harmful by-products.

Scientists reveal the sex wars of the truffle grounds

Allergies and wheezing illnesses in childhood may be determined in the womb

A child's chances of developing allergies or wheezing is related to how he or she grew at vital stages in the womb, according to scientists from the University of Southampton.

The new research, funded by the Medical Research Council (MRC) and the British Lung Foundation, and undertaken at Southampton General Hospital, reveals that fetuses which develop quickly in early pregnancy but falter later in pregnancy are likely to go on to develop allergies and asthma as children. Scientists believe this is due to changes in the development of their immune system and lungs.

Marathons damage the hearts of less fit runners for up to 3 months

Montreal - Is running a marathon good for you or can it damage the heart?

"Marathon runners can be a lot less fit than they think," Dr. Eric Larose today told the Canadian Cardiovascular Congress 2010, co-hosted by the Heart and Stroke Foundation and the Canadian Cardiovascular Society.

Colorectal cancer screening can be expanded by offering it during mammography visits

Offering colorectal cancer screening to poor minority women during mammography visits can effectively expand screening in this otherwise underserved population, although lack of medical insurance remains a significant barrier. That is the conclusion of a new study published early online in Cancer, a peer-reviewed journal of the American Cancer Society. The results highlight the need to find alternative funding sources for colorectal cancer screening from the government or private institutions.
