The Lasting Effects Of Center-Based Care And Insensitive Parenting
A growing number of American children are enrolled in child care and questions remain about how these settings may affect them in both positive and negative ways. A new study published in the May/June 2009 issue of the journal Child Development finds that early interpersonal experiences - center-based child care and parenting - may have independent and lasting developmental effects.

Test Detects Molecular Marker Of Aging In Humans
In 2004, researchers at the University of North Carolina at Chapel Hill Lineberger Comprehensive Cancer Center announced a crucial discovery in the understanding of cellular aging. They found that as cells and tissues age, the expression of a key protein, called p16INK4a, dramatically increases in most mammalian organs. Because p16INK4a is a tumor suppressor protein, cancer researchers are interested in its role in cellular aging and cancer prevention.

Childhood Physical Abuse Linked To Cancer

Childhood physical abuse is associated with elevated rates of cancer in adulthood, according to a new study by University of Toronto researchers. The study, to be published July 15 in the journal Cancer, shows those individuals physically abused in childhood are more likely to develop cancer than those who have not been abused. Childhood physical abuse is associated with 49 per cent higher odds of cancer in adulthood, says Esme Fuller-Thomson of U of T"s Factor-Inwentash Faculty of Social Work and Department of Family and Community Medicine. "Few talk about childhood physical abuse and cancer in the same breath," says Fuller-Thomson. "From a public health perspective, it"s extremely important that clinicians be aware of the full range of risk factors for cancer. This research provides important new knowledge about a potential childhood abuse-cancer relationship." The study"s findings showed the association between childhood abuse and cancer remained significant even after controlling for three major potentially confounding factors: childhood stressors, adult health behaviors (i.e. smoking, physical inactivity, alcohol consumption) and adult socioeconomic status. Co-author Sarah Brennenstuhl, a doctoral student at Uof T, notes that various psychophysiological factors could help to explain the link between childhood physical abuse and cancer. "One important avenue for future research is to investigate dysfunctions in cortisol production - the hormone that prepares us for "fight or flight" -as a possible mediator in the abuse-cancer relationship."
