BACKGROUND To understand and model the impact of pneumococcal conjugate vaccines at the population level, we need to know the transmission dynamics of individual pneumococcal serotypes. We estimated serotype-specific clearance and acquisition rates of nasopharyngeal colonization among Kenyan children. METHODS Children aged 3-59 months who were identified as carriers in a cross-sectional surve...

Left ventricular (LV) midwall shortening (MWS) is subnormal in relation to LV circumferential end-systolic stress (ESS) (ESS-corrected MWS) in many hypertensive patients with normal LV chamber function and predicts subsequent morbidity and mortality. However, little is known of the relations of LV midwall function to demographic and metabolic variables or to arterial geometry. Asymptomatic, unm...

We live in a world consisting of concrete experiences, yet we appear to form abstractions that transcend the details of our experiences. In this contribution, we argue that the abstract nature of our thought is overstated and that our representations are inherently bound to the examples we experience during learning. We present three lines of related research to support this general point. The ...

PURPOSE Penetrating keratoplasty and epikeratoplasty have been utilized in the surgical treatment of keratoconus. Comparison of the relative efficacy of each procedure in achieving visual outcomes has not been achieved due to limited numbers of cases and follow-up in previous series. METHODS All patients who underwent either penetrating keratoplasty or epikeratoplasty for keratoconus between ...

"Spend Less. Eat Well. Feel Better." (SLEWFB) is a 3-hour intervention designed to improve food resource management ability, health, and food security status. This program efficacy trial targeted clients seeking financial aid to prevent homelessness. A randomized controlled design using a 1-hour food safety intervention as a control group was used. Four variables were targeted over a 30-day tim...

We present photometry of six transits of the exoplanet XO-2b. By combining the light-curve analysis with theoretical isochrones to determine the stellar properties, we find the planetary radius to be 0.996 −0.018 RJup and the planetary mass to be 0.565± 0.054 MJup. These results are consistent with those reported previously, and are also consistent with theoretical models for gas giant planets....

Hypnotic Ss received posthypnotic suggestions (a) to begin all sentences to the ostensible experimental (Taffel) task with "he" and "they," and (b) to be unaware of and amnesic for this fact. Waking simulator Ss received identical suggestions preceded by instructions to behave later as though they had been hypnotized when they received the suggestions. During a postexperimental inquiry with a d...
