Carbon nanofibers (CNFs) have attracted significant interest because of their excellent mechanical, electrical, and physical properties. Recent advances in chemical functionalization strategies are anticipated to extend their utility in various applications. In this study, noncovalent methods of CNF functionalization utilizing solution crystallization and precipitation techniques were used to c...

OBJECTIVE To assess whether smoking quit rates and satisfaction with the Washington State tobacco quitline (QL) services varied by race/ethnicity, socioeconomic status, area of residence (that is, urban versus non-urban), or sex of Washington QL callers. METHODS From October 2004 into October 2005, we conducted telephone surveys of Washington QL callers about three months after their initial ...

AIM To document changes in the profile of bacterial isolates from cases of keratitis and changes in their susceptibility to first line antibiotic therapies. METHODS A retrospective review was performed of all bacterial isolates from cases of keratitis seen between 1984 and 1999. In vitro laboratory susceptibilities to antibiotics were determined by the Kirby-Bauer disc diffusion method. The n...

Nowadays, the radiological risk from simple X-ray procedures is well known. The purpose of this work has been to estimate the population risk from digital angiographic and interventional procedures and to compare it with the one from simple procedures in the same population. The population risk has been estimated according to the following quantities: genetically significant dose, somatic signi...

To quantify the effects of methylmercury (MeHg) on amacrine and on ON-bipolar cells in the retina, experiments were performed in MeHgexposed groups of adult trahiras (Hoplias malabaricus) at two dose levels (2 and 6 μg/g, ip). The retinas of test and control groups were processed by mouse anti-parvalbumin and rabbit anti-αprotein kinase C (αPKC) immunocytochemistry. Morphology and soma location...

BACKGROUND Restenosis prediction from published studies is hampered by inadequate sample size and incomplete angiographic follow-up. The prediction of restenosis with the existing variables is poor. The aim of the present study was to include the clinical and angiographic variables commonly associated with angiographic restenosis and develop a prediction model for restenosis from the PRESTO dat...

OBJECTIVE The South Bay Heart Watch is a cohort study designed to determine the significance of coronary calcium in high-risk asymptomatic patients. This is a report of the relative risk (RR) for outcomes of coronary artery calcium in diabetic and nondiabetic subjects. RESEARCH DESIGN AND METHODS A total of 1312 diabetic and nondiabetic subjects underwent risk factor screening and computed to...

BACKGROUND Our objective was to examine the knowledge and treatment decision practice patterns of Canadian surgeons who treat patients with rectal cancer. METHODS A mail survey with 6 questions on staging investigations, management of low rectal cancer, lymph node harvest, surgical margins and use of adjuvant therapies was sent to all general surgeons in Canada. Appropriate responses to surve...

The primary mechanism underlying pre-eclampsia (PE) remains one of the most burning problems in the obstetrics and gynecology. In this study, we performed an expression profiling screen and detected 1312 genes that were differentially expressed (p<0.05 and fold change >1.5) in PE placentas, including LEP and SH3PXD2A. After validating the microarray results, we conducted the quantitative methyl...
