This paper aims to discuss the role and the accuracy of positron emission tomography (PET) and to evaluate computed tomography (CT) contrast enhancement in diagnosing the nature of lung nodules detected by low-dose CT, performed as screening for lung cancer. When applying strict admission criteria to the test, CT contrast enhancement is feasible in 40% of nodules and gives an accurate diagnosis...

UNLABELLED A fluorinated analog of proline amino acid, cis-4-[(18)F]fluoro-L-proline (FP), was tested for potential use in PET for detection and evaluation of pulmonary response to respirable crystalline silica. The purpose of the study was to determine whether PET imaging with FP is sensitive for detection of pulmonary fibrosis. METHODS Experimental silicosis was produced in rabbits by airwa...

The massive amount of plastic waste in our natural environment is a global concern. In this study, recycling to partially replace sand concrete investigated. performance Resin8, unique combination all types plastics and Polyethylene Terephthalate (PET) concrete, has also been Replacement contents 5%, 10%, 15% for by volume were performed. mixes incorporating recycled tested against reference mi...

OBJECTIVE To assess the diagnostic value of whole-body positron emission tomography (PET), computed tomography (CT), magnetic resonance imaging (MRI), and the fusion of PET and CT (PET/CT) and PET and MRI (PET/MRI) in the detection of metastatic disease of gastrointestinal carcinoid tumors. MATERIALS AND METHODS This prospective study included six patients with extensive nonresectable metasta...

First published October 12, 2006; doi:10.1152/japplphysiol.00763.2006.—Positron emission tomography (PET) provides three-dimensional images of the distributions of radionuclides that have been inhaled or injected into the lungs. By using radionuclides with short half-lives, th...

This report summarizes the spread of a raccoon rabies epizootic into New York in the 1990s, the species of animals affected, and human postexposure treatments (PET). A total of 57,008 specimens were submitted to the state laboratory from 1993 to 1998; 8,858 (16%) animals were confirmed rabid, with raccoons the most common species (75%). After exposure to 11,769 animals, 18,238 (45%) persons rec...

BACKGROUND Loss-of-function variants in the gene encoding filaggrin (FLG) are major determinants of eczema. We hypothesized that weakening of the physical barrier in FLG-deficient individuals may potentiate the effect of environmental exposures. Therefore, we investigated whether there is an interaction between FLG loss-of-function mutations with environmental exposures (pets and dust mites) in...

Radiation exposure in positron emission tomography (PET) imaging limits its usage the studies of radiation-sensitive populations, e.g., pregnant women, children, and adults that require longitudinal imaging. Reducing PET radiotracer dose or acquisition time reduces photon counts, which can deteriorate image quality. Recent deep-neural-network (DNN) based methods for image-to-image translation e...

Stress is an insidious health risk that is commonly reported among university students. While research suggests that dog exposure may facilitate recovery from a stress response, little is known about the buffer effect of dog exposure on the stress response to a future stressor. This study examined whether interaction with a therapy dog could reduce the strength of the physiological stress respo...

OBJECTIVE To assess the association between animal exposures and non-Hodgkin's lymphoma (NHL). METHODS Exposure data were collected from 1,591 cases and 2,515 controls during in-person interviews in a population-based case-control study of NHL in the San Francisco Bay Area. Odds ratios (OR) and 95% confidence intervals (95% CI) were adjusted for potential confounders. RESULTS Pet owners had...
