BACKGROUND We evaluated the impact of a community-based tobacco control project that was implemented in the city of Tucson, Arizona, USA, between 1996 and 2001. AIM The project's goal was to reduce the prevalence of youth smoking through change in social norms at schools and in communities and workplaces. As is often the case, these community-based health promotion interventions were implemen...

In this paper we investigate DCT-based embedded zerotree coding of composited videos for multi-point video conferencing. Zerotree coding is a progressive coding method which encodes a video or image into a bit stream with increasing precision. The embedded property is accomplished that all encodings of the same image or video at lower bit rates are embedded in the beginning of the bit stream fo...

A free-floating intraperitoneal mass is extremely rare, and almost all originate from an ovary. Here, we present the first case with an intraperitoneal free-floating autoamputated ovary that caused an acute abdomen in a child and also review the literature. A 4-year-old girl was admitted with signs and symptoms of acute abdomen. At surgery, the patient had no right ovary and the right tube ende...

The primary data of interest came from completed intake interviews of smokers. Using a generalized linear model, we modeled the proportion of Quitline callers who are ready to quit and/or have hig...

OBJECTIVE The public health burden of tobacco-associated diseases in the USA remains high, in part because many people's attempts to quit are unsuccessful. This study examined factors associated with having lifetime or recent attempts to quit smoking among current smokers, based on a telephone survey of Florida adults. METHODS Data from the 2007 telephone-based Florida Behavioral Risk Factor ...

We hypothesized that the ovulatory response of one ovary to FSH would be related positively to the size of the primordial and growing pools of follicles in the other ovary. Nonlactating cows (n = 26) were unilaterally ovariectomized and 2 days later were superovulated. The superovulatory response was classified as Low (< 5 corpora lutea [CL]), Medium (5-14 CL), or High (> 14 CL). Surface follic...
