Behavioral measurements on the water maze show night blindness in albino mice but cortical recordings show no difference between pigmented and congenic albino mice. Consequently we have measured the absolute threshold in albino and pigmented mice using an operant method. The estimated threshold value is -5.3 log cd/m2 for albino mice and -5.5 log cd/m2 for the pigmented mice. We conclude that t...

This paper shows that adding 3D depth information to RGB colour images improves segmentation of pigmented and non-pigmented skin lesion. A region-based active contour segmentation approach using a statistical model based on the level-set framework is presented. We consider what kinds of properties (e.g., colour, depth, texture) are most discriminative. The experiments show that our proposed met...

Trichoblastoma is occasionally observed in association with a pre-existing nevus sebaceous in the Korean literature. However, there has been no report on the pigmented type. Herein, we report the first Korean case of a pigmented trichoblastoma arising from the nevus sebaceous on the forehead. A 28-year-old male presented with a dark nodular lesion within a yellowish plaque on the forehead. The ...

Abstract Lacydonia Marion & Bobretsky, 1875 is the sole genus in family Lacydoniidae Bergström, 1914. We herein describe new species of shohoensis sp. nov. from 2042-m deep bottoms at Shoho Seamount Nishi-Shichito Ridge, Northwest Pacific Ocean. It most similar to L. anapaulae Rizzo et al ., 2016 having a depression on median anterior region and lacking lateral lobes posterior margin prosto...

The genes coding for yellow pigment production in Erwinia herbicola Eho10 (ATCC 39368) were cloned and localized to a 12.4-kilobase (kb) chromosomal fragment. A 2.3-kb AvaI deletion in the cloned fragment resulted in the production of a pink-yellow pigment, a possible precursor of the yellow pigment. Production of yellow pigment in both E. herbicola Eho10 and pigmented Escherichia coli clones w...

The Bayon temple in Angkor Thom, Cambodia has shown serious deterioration and is subject to the formation of various pigmented biofilms. Because biofilms are damaging the bas-reliefs, low reliefs engraved on the surface of sandstone, information about the microbial community within them is indispensable to control biofilm colonization. PCR-denaturing gradient gel electrophoresis (DGGE) analysis...

Bacterial strain Vibrio sp. (PIGB 184) isolated from water samples of the Arabian Sea and identified through 16S rRNA demonstrated the production of pigmentary antioxidants with higher ABTS activities 90.9 ± 0.42 % in comparison with the standard commercial pigmented antioxidant, quercetin 88.8 ± 1.4 %. Antioxidative metabolites of this strain substantially inhibit the lipid peroxidation (LPO) ...

BACKGROUND Outcome measures for atopic dermatitis (AD) patients with pigmented skin have neither been developed nor validated. OBJECTIVE To compare the reliability and validity of four common AD outcome measures in patients with various levels of skin darkness. METHOD The inter- and intra-rater reliability and construct validity of the EASI (Eczema Area and Severity Index), objective-SCORin...

Connexin43 is a major component of the gap junctions between pigmented and non-pigmented cells of the double-layered epithelium in the ciliary body of the eye. We directly tested the hypothesis that gap junctions play a crucial role in the production of the aqueous humor by inactivating the GJA1 (connexin43) gene in the pigmented epithelium with cre-loxP technology. To accomplish this, we cross...
