Minimally Invasive Surgery For Esophageal Cancer Reduces Mortality Rates, Length Of Hospital Stays
Patients with esophageal cancer who require surgery may benefit from having minimally invasive surgery instead of an open esophagectomy, or removal of the esophagus, according to a University of Pittsburgh Cancer Institute (UPCI) phase II study. The results will be presented May 31 at the 45th annual meeting of the American Society of Clinical Oncology (ASCO) in Orlando, Fla.

Seminal Finding Has Major Implications For The Development Of New And Better Vaccines
A research team led by the La Jolla Institute for Allergy & Immunology has identified the specific gene which triggers the body to produce disease-fighting antibodies -- a seminal finding that clarifies the exact molecular steps taken by the body to mount an antibody defense against viruses and other pathogens. The finding, published online today in the prestigious journal Science, has major implications for the development of new and more effective vaccines. The La Jolla Institute"s Shane Crotty, Ph.D., was the lead scientist on the team, which also included researchers from Yale University.

Greater Academic Disengagement In US Teens

In the United States, adolescence is a time when many teens become less interested in academics. A new longitudinal study has found that this disengagement is greater for American teens than for Chinese teens. The study, by psychologists at the Chinese University of Hong Kong and the University of Illinois, Urbana-Champaign, appears in the July/August 2009 issue of Child Development, a journal. It may help explain why Chinese children consistently outperform Americans in academic areas such as math. The researchers followed more than 800 Americans and Chinese from 7th to 8th grade. The students completed questionnaires four times over two years, reporting on how much they valued achievement and how they viewed mastery (specifically, whether they liked to do difficult work in a particular subject). They also reported on their use of constructive learning strategies and how much time they spent on schoolwork outside of school. The youths" grades also were collected. American youths reported being less motivated academically as they made their way through 7th and 8th grades. Over time, they placed less value on achievement, grew less concerned with mastery, used fewer constructive learning strategies, and spent less time studying. In contrast, Chinese youths" reports suggested that the value they placed on achievement, their use of constructive learning strategies, and the time they spent studying stayed stable. "This may be because in China, a higher priority is placed on learning because it is seen as a key to future success and is considered a moral undertaking," explains Qian Wang, assistant professor of psychology at the Chinese University of Hong Kong and the study"s lead author. The study also found that both American and Chinese students became less concerned in middle school with mastering schoolwork. "This decline in both countries may reflect a poor fit between children"s developing psychological needs and school settings," adds Wang. The study was funded by the National Institute of Mental Health. Sarah Hutcheon Society for Research in Child Development
