Opinion: Governments Must Take 'Concrete Action' To Reduce Maternal Mortality, Morbidity
With the U.N. Human Rights Council"s June session coming up, governments have a "chance to prove that they value women"s lives by taking concrete action" to recognize "preventable maternal death as a violation of women"s rights," Mary Robinson and Alicia Yamin, advisory council members of the International Initiative on Maternal Mortality and Human Rights, write in a Boston Globe opinion piece.

Obama, Health Insurers Clash On Public Plan
"President Obama made a detailed case on Tuesday for a new government-administered health insurance plan, but he did not rule out signing a bill that lacks such an option if he cannot win enough support from Democrats in Congress," The New York Times reports. "In a White House news conference, Mr. Obama dismissed as "not logical" the suggestion that a public plan, which is intended to create more competition and therefore act as a brake on the rise of health insurance costs, would undermine the private insurance market. He argued that a government-run plan competing with private insurers would be an "important tool to discipline insurance companies" and scoffed at complaints that it could drive some out of business."

Two of them returned from a country where swine flu exists, while another is linked to a previously confirmed case in England - the s of the other two are still being investigated, the HPA reported.

Carbon Monoxide Prevents Clotting

Researchers led by Drs. James F. George and Anupam Agarwal at the University of Alabama at Birmingham have found that carbon monoxide (CO) can protect against arterial clotting. They report their data in the July 2009 issue of the American Journal of Pathology. Carbon monoxide poisoning is extremely toxic; exposure prevents oxygen delivery to body tissues and is often fatal. However, inflamed or injured tissues upregulate heme oxygenase-1 (HO-1), a protein that both protects cells and produces CO, suggesting that low levels of CO may have protective effects. To determine if HO-1 and CO can protect against arterial clotting, Chen et al examined clotting mechanisms in mice that received arterial transplants. Absence of HO-1 in these mice resulted in significant mortality due to arterial clotting; however, treatment with a CO-releasing molecule both decreased clotting and improved survival. Drs. George, Agarwal, and colleagues conclude that HO-1/CO plays an "important role ò€¦[in] protection against vascular arterial thrombosis in murine aortic allotransplantation."
