There is a tremendous need for a comprehensive review of the many facets of the epidemiology of prostate cancer. For well over three decades, we have struggled to identify etiologic factors that might explain the almost 10-fold differences in the incidence and mortality of prostate cancer between various geographic and ethnic populations. These rate differences can change dramatically during po...

The sun protection factor (SPF) of sunscreens is determined by a testing protocol that specifies a sunscreen application rate of 2 mg/cm(2) on the skin. Most people, for cosmetic and economic reasons, only apply enough sunscreen to achieve an SPF of about a third or even a quarter of the level stated on the product. To increase public awareness of the problem, manufacturers could be required to...

. DESIGN Intervention study. 
. SETTING A university hospital in a large midwestern metropolitan area and its outpatient chemotherapy infusion clinic.
. SAMPLE 163 staff (nurses, pharmacists, and pharmacy technicians) who work with a...

A general procedure for the nucleophilic addition of organozinc halides with nitrones in the presence of trimethylsilyl chloride has been developed. Trimethylsilyl chloride was found to be both an indispensable reaction promoter and a ready hydroxylamine protective agent in these reactions. The produced O-(trimethylsilyl)hydroxylamines can be easily reduced into corresponding amines just by a z...

Developing sensor agents that can be deployed untethered in the field presents significant challenges in adapting to hardware, communication, power and environmental limitations. Real-world characteristics dictate agent behavior and operating strategies, sometimes quite differently from often held assumptions and intuitions. In this article, we describe the sensor-agent hardware and blackboard-...

The radio frequency identification (RFID) is a technology for automatic identification of items, particularly in supply chain, but it is becoming increasingly important for industrial applications. Unlike barcode technology that detects the optical signals reflected from barcode labels, RFID uses radio waves to transmit the information from an RFID tag affixed to the physical object. In contras...

OBJECTIVES This paper describes the sun-related behaviour of parents and their children, ages 5-12 years. METHODS In-person interviews were conducted with parents and observations of parents and their children to ascertain: 1) parents' self-reported use of sunscreen, 2) parent-proxy reports of children's sunscreen use, and 3) observations of parents' and children's use of shade, hats and prot...

The purpose of this study was to evaluate the impact of the integral attention to the health of pregnant adolescents and adolescent mothers, having follow-up from the Integral Support Program for the Pregnant Teen (ISPPT), with the intention to determine quality of life and prevent repeat pregnancy. A prospective study comprised 85 adolescents attended by the ISPPT between January 2002 and June...

Campaigns using television, radio and print media were conducted over three summers in New South Wales, Australia, aiming to increase the use of sun protection measures among children under 12 years. The evaluation entailed cross-sectional telephone surveys before and after each of the first two campaigns and following the third campaign. The study group were parents of children under 12 years....

Cesium chloride density gradients are frequently used for virus concentration or purification in the preparation of human feces for examination by electron microscopy, Disruption of some of the fecal viruses occurs if they are pelleted from the density gradient in an additional concentration step. This report highlights an important limitation imposed by the use of cesium chloride as a density ...
