'Marketplace' Examines Women's Decisions To Have Children During Recession
American Public Media"s "Marketplace" on Tuesday examined how some women and their partners are deciding to have more children, a choice that runs contrary to birth rate trends during past economic recessions. Stephanie Ventura, a demographer at the National Center for Health Statistics, said that in previous severe economic recessions, birth rates have decreased or stabilized. It is too soon to tell whether the current recession will affect birth rates because the most recent birth data are from July 2008. Ventura also noted that the data will encompass a broad range of personal choices, including people who delayed pregnancy and those who went forward with plans to have children despite the recession.According to "Marketplace," some women who have lost jobs but have other s of income believe that having time away from work is a good opportunity to plan a pregnancy. Ellen Galinsky, president of the Families and Work Institute, called this rationale "very clever" but added that being out of work only "gives you a break as long as you"ve got health insurance coverage, or unemployment, or some other of income that you can depend on." Galinsky said, "This country is increasingly becoming family centric. There is much more of an emphasis on children and families and being with them and taking good care of them than there has been before" (Keith, "Marketplace," American Public Media, 6/16).

Improving Heart Function In Mouse Model Following Heart Attack

One approach being developed as a way to improve heart function following heart attack is the injection of heart stem/progenitor cells directly into the heart. Now, a team of researchers, at Tokyo Women"s Medical University, Japan, and Chiba University Graduate School of Medicine, Japan, has found that transplanting sheets of clonally expanded heart cells expressing the protein Sca-1 (cells that are heart stem/progenitor cells and that the authors term CPCs) improves heart function after a heart attack in mice. The team, led by Katsuhisa Matsuura and Issei Komuro, found that CPCs not only formed heart muscle cells but also secreted a soluble molecule (sVCAM-1) that induced the migration of endothelial cells (which help form new blood vessels) and CPCs and prevented heart muscle cells dying from oxidative stress. In the mouse model of heart attack, preventing sVCAM-1 from binding to the protein VLA-4 inhibited the formation of new blood vessels and blocked CPC migration and survival, leading to a decreased ability of the transplanted CPC sheets to improve heart function. The authors conclude that these data provide new insight into the mechanisms by which heart stem/progenitor cells improve heart function following heart attack.
