Four horses presenting for lameness were diagnosed with unilateral osteochondral fragmentation (OCF) of the palmarolateral/plantarolateral aspect distal phalanx within interphalangeal joint (DIPJ). Histological evaluation one case supported a diagnosis osteochondritis dissecans (OCD), patient age and history from two cases suggesting traumatic origin. Lesion appearance on conventional radiograp...

Allergy and autoimmunity are both examples of deregulated immunity characterized by inflammation and injury of targeted tissues that have until recently been considered disparate disease processes. However, recent findings have implicated mast cells, in coordination with granulocytes and other immune effector cells, in the pathology of these two disorders. The BioBreeding (BB) DRlyp/lyp rat dev...

The color of serpentine jade is affected not only by the chemical composition, but also some external factors. In this research, we quantitatively analyzed and influence light sources, backgrounds, thickness on its color. Thirty-six gem-quality samples from Tai’an, Shandong, China, were studied using eighteen Munsell neutral gray three sources (D65, F2, A). It was found that D65 source appeared...

Under conditions of adaptation to a steady neutral field (metameric to Daylight Illuminant D65), forced-choice thresholds for color discrimination were measured for brief targets presented to the human fovea. Measurements were made along +45° and -45° lines in a MacLeod-Boynton chromaticity space scaled so that the locus of unique yellow and unique blue lay at -45°. The lines were symmetrical r...

The photostability of tretinoin tocoferil was investigated under irradiation with three kinds of lamps, i.e., a cool white fluorescent lamp, a UV-A fluorescent lamp and a D65 fluorescent lamp. A combination of the cool white fluorescent lamp and the UV-A fluorescent lamp, and the D65 lamp having relative spectral power distribution similar to that of direct daylight, correspond to options 2 and...

To speed the development of novel camera architectures we proposed a method, L (Local, Linear and Learned), that automatically creates an optimized image processing pipeline. The L method assigns each sensor pixel into one of 400 classes, and applies class-dependent local linear transforms that map the sensor data from a pixel and its neighbors into the target output (e.g., CIE XYZ rendered und...

PURPOSE Perceived color of ceramics changes by the spectral power distribution of ambient light. This study aimed to quantify the amount of shifts in color and color coordinates of clinically simulated seven all-ceramics due to the switch of three ambient light sources using a human vision simulating spectroradiometer. MATERIALS AND METHODS CIE color coordinates, such as L*, a* and b*,of cera...

A psychophysical experiment has been conducted to test the threshold of color difference in displayed images under different viewing conditions. Four ISO SCID 400 images N2, N3, N5 and N7 were used as test images, whose colors were altered in lightness, chroma and hue attributes systematically to form the test image pairs with the original ones. The average color difference in all image pairs r...

The visual impression of an artistic painting is influenced both by the colour and by the specific spectral structure of the rendering light source. The relationship between illuminant spectral structure and visual appearance assumes particular relevance with the advent of light sources with almost arbitrary spectral distribution, like modern LED based lighting. The aim of this work was to stud...
