The suitability of using optical-density (OD) measurements after a 6-h incubation period to determine bacterial contamination on hatching eggs was evaluated. A total of 154 hatching eggs, from five different flocks, were examined visually and bacterial counts and OD measurements of egg washings after 6 h of incubation at 37 degrees C were carried out to determine the levels of bacterial contami...

Computed tomography (CT) is superior for the detection of substances with low radiolucency in comparison with abdominal roentgenograms. In the present study, medical chart review was retrospectively performed for patients who were admitted and underwent plain CT including the stomach on arrival to investigate whether CT is useful for diagnosing overdose (OD). The subjects were divided into pati...

Background Previous studies used unequal or high daily dosages of methimazole (MMI) to compare the efficacy of once daily dose regimen (OD-MMI) with that of divided daily doses regimen (DD-MMI) in inducing euthyroidism. Objectives To compare the efficacy of OD-MMI to that of DD-MMI using low daily dosage of MMI in inducing euthyroidism. Methods Fifty patients with clinically nonsevere Grave...

INTRODUCTION Diffuse idiopathic skeletal hyperostosis (DISH) and ossification of the posterior longitudinal ligament (OPLL) are both characterized as ossification in paravertebral ligaments and sometimes present simultaneously, however, the bone metabolism in patients with cervical OPLL accompanying/not accompanying DISH has not well been studied. Thus, a retrospective analysis was performed to...

The aim of this study was to determine the effect of the exposure of different endodontic materials to different dye solutions by evaluating the optical density of the dye solutions. Seventy-five plastic tubes were filled with one of the following materials: AH Plus, Sealapex, Portland cement, MTA (Angelus and Pro Root) and fifteen control plastic tubes were not. Each specimen of material and c...

To investigate the role of visual experience for the gross layout of ocular dominance (OD) columns in the visual cortex, I compared the respective patterns in normally raised and strabismic cats. OD domains were visualized by (1) transneuronal labeling of the afferents from the left or right eye with intraocular 3H-proline injections or (2) 14C-2-deoxyglucose autoradiography after monocular vis...

Opiate dependence (OD) and borderline personality disorder (BPD), separately and together, are significant public health problems with poor treatment outcomes. BPD is associated with difficulties in emotion regulation, and brain-imaging studies in BPD individuals indicate differential activation in prefrontal cingulate cortices and their interactions with limbic regions. Likewise, a similar net...

The ocular dominance (OD) shift that occurs in visual cortex after brief monocular deprivation (MD) is a classic model of experience-dependent cortical plasticity. It has been suggested that OD plasticity in layer 2/3 of visual cortex precedes and is necessary for plasticity in the thalamocortical input layer 4. Here, we show in mouse visual cortex that rapid OD plasticity occurs simultaneously...

Ocular dominance (OD) columns, alternating regions of left and right eye input in the visual cortex of higher mammals, have long been thought to develop from an initially intermingled state by an activity-dependent process. While indirect evidence points to potential alternative mechanisms based on molecular cues, direct proof for a molecular difference between left- and right eye columns is mi...
