In this study we tested the hypothesis that fusion mediated by the influenza virus hemagglutinin
(HA) is a cooperative event. To so this we characterized 3T3 cell lines that express HA at …

Revised Manuscript Received October 11, 1991 abstract: Color vision in humans is mediated
by three pigments from retinal cone photoreceptor cells: blue, green, and red. We have …

We tested the role of the “spring-loaded” conformational change in the fusion mechanism of
the influenza hemagglutinin (HA) by assessing the effects of 10 point mutants in the region …

Microarray gene-expression profiles are generally validated one gene at a time by real-time
RT-PCR. We describe here a different approach based on simultaneous mutual validation of …

Structural changes involving bacteriohodopsin proline residues have been investigated by
Fourier transform infrared difference spectroscopy. Bacteriohodopsin (bR)-producing …

OBJECTIVE: To develop an observational coding instrument for evaluating the fidelity and
quality of brief behavioral change interventions based on the behavioral theories of the 5 A's, …

Background and Objectives: There is little research on training medical students in smoking
cessation counseling (SCC). This study aimed to determine if a personal digital assistant (…

Background: Surveys reveal limited screening and counseling for alcohol misuse by primary
care physicians despite evidence-based recommendations. We developed and evaluated …

Background HealthHeritage is a web-based family health history tool designed to improve the
use of family health history information. It will provide an efficient way for patients to collect …

Background The human genome project is providing a wealth of information about the genetic
basis of common diseases. This information has implications for clinical practice however; …
