Research has been initiated to determine a set of six basis colorants which are the best representation of artwork such as paintings. That is, their spectral information can be accurately reconstructed by linear combinations of the six estimated colorants. Since each painting is possibly created by different colorants, the six estimated colorants are image dependent. The clue leading to the six...

A heart is described pathologically in which the aorta emerged from the right ventricle and was not related to the ventricular septal defect, while the pulmonary trunk emerged from both ventricles, but mostly the right, and was related to the ventricular septal defect. This Taussig-Bing arrangement of vessels was coupled with the presence of the aortic orifice to the left and the pulmonic orifi...

Estimating the frequency of metameric surfaces in natural scenes usually requires many comparisons of surface colors to determine which are visually indistinguishable under one light but distinguishable-by a certain criterion degree-under another. The aim here was to test the predictive power of a simpler approach to estimation based on the entropy of colors. In simulations with 50 hyperspectra...

Cutaneomeningospinal angiomatosis, or Cobb syndrome, is a rare metameric developmental disorder presenting as an extradural-intradural vascular malformation that involves bone, muscle, skin, spinal cord, and nerve roots. A 14-year-old girl with a red nevus involving the T6-9 dermatomes on the left side of her back presented with a 5-year history of bowel and bladder incontinence, paraplegia, ...

By cross hybridization with the mammalian growth-related protein, GAP-43, we have isolated several Drosophila cDNAs and genomic sequences. These sequences correspond to a single copy gene that encodes two developmentally regulated transcripts 2.4 and 2.0 kb in length. The predicted protein sequence from the cDNAs contains a stretch of 20 amino acids closely related to the mammalian GAP-43 prote...

objective: dental caries is a common infectious disease. streptococcus mutans is the prevalent decay microorganism. the anti streptococcus mutans activity of non fermented and semi-fermented tea has been shown. the aim of this study was to determine the anti streptococcus mutans activity of iranian green and black tea (non fermented and fermented type). materials and methods: the study was expe...

The effect of black glutinous rice bran inclusion used in diets of Nile tilapia was  studied in fish with an initial weight of 8.76±0.17g per fish and fed with experimental diets supplemented with black glutinous rice bran at 0 (control), 50, 100, 150 and 200 g kg-1 for 60 days. The results of phytochemical analyses of black rice bran showed that the total anthocyanin, phenolic, tannin and phyt...
