    Atomic-scale structure of the SrTiO3(001)-c(6x2) reconstruction: Experiments and first-principles calculations

    Get PDF
    The c(6x2) is a reconstruction of the SrTiO3(001) surface that is formed between 1050-1100oC in oxidizing annealing conditions. This work proposes a model for the atomic structure for the c(6x2) obtained through a combination of results from transmission electron diffraction, surface x-ray diffraction, direct methods analysis, computational combinational screening, and density functional theory. As it is formed at high temperatures, the surface is complex and can be described as a short-range ordered phase featuring microscopic domains composed of four main structural motifs. Additionally, non-periodic TiO2 units are present on the surface. Simulated scanning tunneling microscopy images based on the electronic structure calculations are consistent with experimental images

    Video feedback intervention for cognitively impaired older drivers: A randomized clinical trial

    Get PDF
    Introduction: This clinical trial aimed to determine whether in-car video feedback about unsafe driving events (UDE) to cognitively impaired older drivers and family members leads to a reduction in such driving behaviors. Methods: We randomized 51 cognitively impaired older drivers to receive either (1) a weekly progress report with recommendations and access to their videos, or (2) video monitoring alone without feedback over 3 months. Results: UDE frequency/1000 miles was reduced by 12% in feedback (rate ratio [RR] = 0.88, 95% confidence interval [CI] = .58-1.34), while remaining constant with only monitoring (RR = 1.01, 95% CI = .68-1.51). UDE severity/1000 miles was reduced by 37% in feedback (RR = 0.63, 95% CI = .31-1.27), but increased by 40% in monitoring (RR = 1.40, 95% CI = .68-2.90). Cognitive impairment moderated intervention effects ( Discussion: Results suggest the potential to improve driving safety among mild cognitively impaired older drivers using a behavior modification approach aimed at problem behaviors detected in their natural driving environment

    Validated Sandwich ELISA for the Quantification of von Willebrand Factor in Rabbit Plasma

    von Willebrand Factor (vWF) is a multimeric plasma protein important for platelet plug formation. As part of its haemostatic role, it is released from endothelial cells during vascular stress or injury and is considered an excellent biomarker of endothelial function. Currently, there are no validated kits available to measure vWF in rabbits. We developed a sensitive and reproducible sandwich enzyme-linked immunosorbent assay (ELISA) for detection of vWF in rabbit plasma using commercially available antibodies and reagents. Purified human vWF was used as a calibrator standard with a dynamic range of 1.56–100 ng/mL. The Minimum Required Dilution for rabbit plasma was 1:100. When plasma was spiked with 3.76 or 10 ng/mL vWF, recovery was 108 ± 2% and 93 ± 2%, respectively. Intra- and inter-assay precision for 8 rabbit plasma samples were 3% and 4%, respectively. The Minimum Detectable Concentration was 254 pg/mL for purified human vWF and 1:10,700 dilution of cholesterol-fed rabbit plasma, and the Reliable Detection Limits were 457 pg/mL and 1:5940. Three freeze-thaw cycles significantly decreased vWF concentrations for purified human vWF and 2 of 3 plasma samples assayed. This ELISA provides sensitive and reproducible measurements of rabbit plasma vWF, which is an important biomarker for cardiovascular research

    Investigating the Influence that Service in a Pro Bono Clinic has on a First Full-Time Clinical Education Experience from the Perspective of Students and their Clinical Instructors

    Purpose: Academic physical therapy programs strive to foster student readiness for full-time clinical education experiences in a variety of ways. This research looks at one program who has students participate in a student-run pro bono clinic for at least 60 hours prior to the first full-time clinic experience. The purpose of the study is to explore the influence that participation in this pro bono clinic has on a first full-time clinical education experience from the perspective of both the student and the clinical instructor (CI). Methods: Qualitative methodology was employed to gain the perspectives of 29 students and their respective CIs. Data collection included student journals and focus groups, and CI Likert-scale rankings and open-ended questions upon midterm calls. Data points were triangulated through iterative data analysis. Results: CIs rated students high in the eight categories that were triangulated to student data. The themes that were strongest among both students and Cis included comfort with client interaction, interaction with CIs, and cultural competency. Additional themes included documentation, interprofessional interaction, examination, clinical reasoning and intervention. An overarching theme was that students were well-prepared and functioning at high levels of competency for a first full-time clinical experience. Conclusions: Participation in a student-run pro bono clinic helps to facilitate student readiness for a first full-time clinical education experience according to both student perceptions and CI ratings

    Emergent Strain of Human Adenovirus Endemic in Iowa

    Get PDF
    We evaluated 76 adenovirus type 7 (Ad7) isolates collected in Iowa from 1992 to 2002 and found that genome type Ad7d2 became increasingly prevalent. By 2002, it had supplanted all other Ad7 genome types. The association of Ad7d2 with severe illness and death calls for heightened public health concern

    Multiorgan WU polyomavirus infection in bone marrow transplant recipient

    Get PDF
    WU polyomavirus (WUPyV) was detected in a bone marrow transplant recipient with severe acute respiratory distress syndrome who died in 2001. Crystalline lattices of polyomavirus-like particles were observed in the patient’s lung by electron microscopy. WUPyV was detected in the lung and other tissues by real-time quantitative PCR and identified in the lung and trachea by immunohistochemistry. A subset of WUPyV-positive cells in the lung had morphologic features of macrophages. Although the role of WUPyV as a human pathogen remains unclear, these results clearly demonstrate evidence for infection of respiratory tract tissues in this patient
