Advances in optical neuroimaging techniques now allow neural activity to be recorded with cellular resolution in awake and behaving animals. Brain motion in these recordings pose a unique challenge. The location of individual neurons must be tracked in 3D over time to accurately extract single neuron activity traces. Recordings from small invertebrates like C. elegans are especially challenging because they undergo very large brain motion and deformation during animal movement. Here we present an automated computer vision pipeline to reliably track populations of neurons with single neuron resolution in the brain of a freely moving C...

BACKGROUND/OBJECTIVES: U.S. adults and children are equally likely to have allergic contact dermatitis. Historically the narrow geographic location of data-reporting providers has quantitatively and qualitatively limited the pediatric contact dermatitis data. The Pediatric Contact Dermatitis Registry was used to evaluate self-identified pediatric patch test providers within the United States with regard to demographic characteristics, geographic location, and practice patterns. METHODS: A wide range of U...

REVIEW
Zhiying Ji, Nicholas S Ball, Matthew J LeBaron
Mutagenicity is an important toxicological endpoint that requires thorough evaluation during the industrial chemical registration process. Regulatory requirements for mutagenicity assessment in registration of industrial chemicals vary in geographic regions (and in some cases by intended application). Here we compile the mutagenicity testing requirements for registration of industrial chemicals from representative geographic regions (in alphabetical order), that is Australia, Brazil, Canada, China, European Union (EU), India, Japan, South Korea, Taiwan, and United States (US)...

The United States Environmental Protection Agency's (USEPA) ambient water quality criteria (AWQC) for lead (Pb) in saltwater were developed in 1984. The acute and chronic criteria are 210 µg/L and 8.1 µg/L dissolved Pb, respectively. Because data were limited in 1984, the chronic criterion was derived using an acute-chronic ratio (ACR), but there are now sufficient toxicity data such that an ACR is no longer needed. Based on the data now available, the proposed updated acute and chronic saltwater Pb AWQC (following USEPA methods) are 100 and 10 µg/L, respectively...

PURPOSE: One of the major challenges in electromagnetic navigated bronchoscopy is the navigation accuracy. An initial rigid image-to-patient registration may not be optimal for the entire lung volume, as the lung tissue anatomy is likely to have shifted since the time of computer tomography (CT) acquisition. The accuracy of the initial rigid registration will also be affected throughout the procedure by breathing, coughing, patient movement and tissue displacements due to pressure from bronchoscopy tools...

In vivo magnetic resonance imaging (MRI) was used to investigate regional and global brain atrophy in the neurodegenerative Niemann Pick Type C1 (NPC1) disease mouse model. Imaging experiments were conducted with the most commonly studied mouse model of NPC1 disease at early and late disease states. High-resolution in vivo images were acquired at early and late stages of the disease and analyzed with atlas-based registration to obtain measurements of twenty brain region volumes. A two-way ANOVA analysis indicated eighteen of these regions were different due to genotype and thirteen showed a significant interaction with age and genotype...

Contrast-enhanced digital mammography (CEDM) is an alternative to conventional X-ray mammography for imaging dense breasts. However, conventional approaches to CEDM require a double exposure of the patient, implying higher dose and risk of incorrect image registration due to motion artifacts. A novel approach is presented, based on hyperspectral imaging, where a detector combining positional and high-resolution spectral information (in this case based on Cadmium Telluride) is used. This allows simultaneous acquisition of the two images required for CEDM...

Recent research has demonstrated the importance of global changes to the functional organization of brain network following stroke. Resting functional magnetic resonance imaging (R-fMRI) is a non-invasive tool that enables the measurement of functional connectivity (FC) across the entire brain while placing minimal demands on the subject. For these reasons, it is a uniquely appealing tool for studying the distant effects of stroke. However, R-fMRI studies rely on a number of premises that cannot be assumed without careful validation in the context of stroke...

Determining brand name similarity is vital in areas of trademark registration and brand confusion. Students rated the orthographic (spelling) similarity of word pairs (Experiments 1, 2, and 4) and brand name pairs (Experiment 5). Similarity ratings were consistently higher when words shared beginnings rather than endings, whereas shared pronunciation of the stressed vowel had small and less consistent effects on ratings. In Experiment 3 a behavioral task confirmed the similarity of shared beginnings in lexical processing...
