A recent study found that individuals experiencing chest pain who had electrocardiogram (ECG or EKG) assessments prior to arriving at the hospital experienced a significantly reduced time-to-treatment or door-to-balloon (D2B) time. When EMS personnel responding to cardiac emergencies obtained ECGs of the subjects in the field, the mean D2B time was 60.2 minutes compared with 90.5 minutes for in-hospital ECGs.

Ice Age climate records from an Arizona stalagmite link the Southwest's winter precipitation to temperatures in the North Atlantic, according to new research.

The finding is the first to document that the abrupt changes in Ice Age climate known from Greenland also occurred in the southwestern U.S., said co-author Julia E. Cole of the University of Arizona in Tucson.

Springtime ozone levels above western North America are rising primarily due to air flowing eastward from the Pacific Ocean, a trend that is largest when the air originates in Asia. These increases in ozone could make it more difficult for the United States to meet Clean Air Act standards for ozone pollution at ground level, according to a new international study. Published online Wednesday, Jan. 20, in the journal Nature, the study analyzed large sets of ozone data captured since 1984.

London, Ontario (January 20, 2010): Critical Outcome Technologies Inc. (COTI) (TSX Venture: COT)announced more positive results today from animal experiments carried out at a prominent Canadian cancer research facility. This new series of experiments adds to the impressive data package for COTI-2, demonstrating efficacy both as a single agent and in combination with current first line therapies, as well as low toxicity in several different animal models of human cancers.

Could powering an iPod or cell phone become as easy as plugging it into your tee shirt or jeans, and then recharging the clothing overnight? Scientists in California are reporting an advance in that direction with an easier way of changing ordinary cotton and polyester into "conductive energy textiles" — e-Textiles that double as a rechargeable battery. Their report on the research appears in ACS' Nano Letters, a monthly journal.

Men who buy fake internet drugs for erection problems can face significant risks from potentially hazardous contents and bypassing healthcare systems could leave associated problems like diabetes and high blood pressure undiagnosed. That's the warning just published online by IJCP, the International Journal of Clinical Practice.

Medical and pharmaceutical experts from the UK, Sweden and USA carried out a detailed review of the growing problem of counterfeit drugs. Estimates suggest that up to 90 per cent of these illegal preparations are now sold on the internet.

A team of chemists from the University of Valencia (UV) has confirmed that the substance used to hermetically seal an amphora found among remains at Lixus, in Morocco, was pine resin. The scientists also studied the metallic fragments inside the 2,000-year-old vessel, which could be fragments of material used for iron-working.

Current evidence suggests that using Doppler ultrasound in high-risk pregnancies to monitor a fetus' health may reduce caesarean sections and the number of babies who die, according to a new Cochrane Systematic Review.

Intensive home-based nursing in HIV/AIDS patients significantly improves self-reported knowledge of HIV, awareness of medications, and self-reported adherence to medication programmes, according to a new Cochrane Systematic Review. One home-based care trial included in the review also significantly impacted on HIV stigma, worry, and physical functioning. It did not, however, help improve depressive symptoms, mood, general health, and overall functioning.

Researchers from the NHS in Cornwall, the Peninsula Medical School, the Agency for Health Technology Assessment in Warsaw and the University of Birmingham have analysed 12 studies relating to cardiac rehabilitation and found no difference in health outcomes for patients who receive cardiac rehabilitation in a clinical setting or at home. The research paper is published in BMJ Online/bmj.com at 00:01am on Wednesday 20th January 2010.

Deep within the Kairei Indian hydrothermal vent field, two-and-one-half miles below the central Indian Ocean, scientists have discovered a gastropod mollusk, whose armor could improve load-bearing and protective materials in everything from aircraft hulls to sports equipment.

The centuries old game of curling is being put under the scrutiny of 21st century technology in a bid to help Canada's best curlers throw their way to gold at the Vancouver Winter Olympics.

University of Alberta researchers, Pierre Baudin and Rob Krepps, are analyzing the technical aspects of the game to determine the best way to deliver a curling stone. The research goal is to ensure optimum performance from Canada's curlers at the 2010 Olympic and Paralympic games.

Acknowledging that the idea of rationing health care, particularly at the end of life, may incite too much vitriol to get much rational consideration, a Johns Hopkins emeritus professor of neurology called for the start of a discussion anyway, with an opinion piece featured in this month's issue of the Journal of Medical Ethics.
