A service performing very early abortions in a district general hospital uses menstrual aspiration, which enables abortion to be carried out early, easily, safely, and simply. Menstrual aspiration avoids interference with routine gynaecological work and permits an operator to widen his criteria for accepting patients for termination. From September 1975 to April 1977 123 cases were referred and...

Bves was discovered in 1999 by two independent laboratories using screens to identify novel genes that were highly expressed in the developing heart (Reese et al., 1999; Andree et al., 2000). As an evolutionarily conserved transmembrane protein, Bves is postulated to play a role in cell adhesion and cell motility. In studies of Bves protein disruption, there have been multiple phenotypes, but f...

A large number of models that are employed in the field of concurrent systems’ design, such as Petri nets, Signal Transition Graphs, gate-level circuits, dataflow structures have an underlying static graph structure. Their semantics, however, is defined using additional entities, e.g. tokens or node/arc states, which collectively form the overall state of the system. We jointly refer to such fo...

In Korean culture, the names of family members are recorded in special family books. This makes it possible to follow the distribution of Korean family names far back in history. It is shown here that these name distributions are well described by a simple null model, the random group formation (RGF) model. This model makes it possible to predict how the name distributions change and these pred...

NANCY W. DICKEY, MD A bit more than a decade ago, the country was bombarded by a series of headlines announcing tragic medical errors that caused pain, increased costs, and even death to the patients involved. As president of the American Medical Association (AMA), I was asked repeatedly about how Bthe best health care system in the world[ could allow mistakes like the ones being reported to oc...

Results: California Adventists have higher life expectancies at the age of 30 years than other white Californians by 7.28 years (95% confidence interval, 6.59-7.97 years) in men and by 4.42 years (95% confidence interval, 3.96-4.88 years) in women, giving them perhaps the highest life expectancy of any formally described population. Commonly observed combinations of diet, exercise, body mass in...
