Odontogenic sinus tracts are the most common cause of a chronically draining papule of the face and neck. Sinus tracts of dental origin opening on the skin with the absence of oral symptoms are often misdiagnosed and can result in inappropriate and ineffective treatment. Cutaneous sinus tracts of odontogenic origin usually appear more commonly in the submandibular or submental regions. A case o...

For many people, the corner store remains the main grocer, or the only source of sustenance in minority communities. This study examined the distribution of corner stores as a future reference point to provide healthy food access to predominantly African American communities that lack full service grocery stores. Business data was obtained from respective county by use of Standard Industrial Co...

OBJECTIVE Diffusion magnetic resonance imaging (MRI) studies have demonstrated acute white matter changes following prolonged febrile seizures (PFS), but their longer-term evolution is unknown. We investigated a population-based cohort to determine white matter diffusion properties 8 years after PFS. METHODS We used diffusion tensor imaging (DTI) and applied Tract-Based Spatial Statistics for...

Measurements of water molecule diffusion along fiber tracts in CNS by diffusion tensor imaging (DTI) provides a static map of neural connections between brain centers, but does not capture the electrical activity along axons for these fiber tracts. Here, a modification of the DTI method is presented to enable the mapping of active fibers. It is termed dynamic diffusion tensor imaging (dDTI) and...

Eukaryotic transcriptional regulation is mediated by the organization of nucleosomes in promoter regions. Most Saccharomyces cerevisiae promoters have a highly stereotyped chromatin organization, where nucleosome-free regions (NFR) are flanked by well-ordered nucleosomes. We have found that yeast promoters fall into two classes differing in NFR sharpness, and that this distinction follows a kno...

Among host-dependent bacteria that have evolved by extreme reductive genome evolution, long-term bacterial endosymbionts of insects have the smallest (160-790 kb) and most A + T-rich (>70%) bacterial genomes known to date. These genomes are riddled with poly(A) tracts, and 5-50% of genes contain tracts of 10 As or more. Here, we demonstrate transcriptional slippage at poly(A) tracts within gene...

PURPOSE In order to better understand whether white matter structural deficits are present in strabismic amblyopia, we performed a survey of the tissue properties of 28 major white matter tracts using diffusion and quantitative magnetic resonance imaging approaches. METHODS We used diffusion-based tensor modeling and a new quantitative T1 protocol to measure fractional anisotropy (FA), mean d...

White matter (WM) fiber bundles of the brain can be delineated by diffusion tractography utilizing anatomical regions-of-interest (ROI). These ROIs can specify seed regions in which tract generation algorithms are initiated. Interactive identification of such anatomical ROIs enables the detection of the major WM fiber tracts, but suffers from inter-rater and intra-rater variability, and is time...

Amyotrophic lateral sclerosis (ALS) is a progressive motor neuron disease with poor prognosis. Previous DW-MRI based studies in ALS on WM tracts showed a decrease of FA in tracts related to the motor system. Recent evidence suggests that extra-motor tracts are also affected by ALS. This paper aims to analyse the cingulum tracts of ALS patients and controls. To do so, we introduce kernel matchin...
