A vkry considerable number of cases of this condition are now referred to this department for diagnosis from Colonel Acton's skin outpatient clinic at the Calcutta School of Tropical Medicine since attention was first drawn to it, and at least two fresh cases are seen every week. In the early stage of the disease, when the lesions consist of white, non-pigmented tiny spots on the skin, it is ve...

Applying and parameterizing advanced visualization tools for solving different problems can be difficult for users, who are not necessarily visualization experts. The visualization community has begun to address this problem by developing assistive approaches under different labels. In this work, we propose an initial version of a characterization scheme for guidance in visualization. With the ...

Pseudoceros astrorum n. sp. is characterized by a smooth dorsal surface with a brown ground colour, and with net-like pattern of small black granules, white spots of different sizes uniformly distributed, a thin black sub-marginal band, and a white marginal rim. The pseudotentacles are dark brown with white tips and the anterior margin and cerebral region is devoid of pigmentation. The male sys...

A method of combining optical skin images obtained at different illumination angles is proposed to reduce the effect of specular reflection in normal white light clinical skin images in order to avoid optical interference with the analysis of skin line pattern. A weighted average image with weights determined by independent component analysis of the images shows a demonstrable reduction in the ...

A 68-year-old Japanese woman underwent radiotherapy for gastric lymphoma. Although lymphangiectasia was sparsely observed in the second portion of the duodenum before radiotherapy, the number of pinpoint white spots obviously increased after the treatment. Although the duodenal lymphangiectasia gradually progressed, the patient had no features of protein-losing enteropathy. This case highlights...

Solar lentigines are benign, brownish lesions that occur on light exposed skin surfaces from age 30 onwards, as a sign of photoaging. As they are of cosmetic importance to many patients, different therapeutic modalities have been tried to remove these unwanted spots. The recent development of short-pulsed, pigment-specific lasers has enabled physicians to selectively destroy the pigment within ...

Fas (CD95, APO-1, TNFRSF6) is a TNF receptor superfamily member that directly triggers apoptosis and contributes to the maintenance of lymphocyte homeostasis and prevention of autoimmunity. Although FADD and caspase-8 have been identified as key intracellular mediators of Fas signaling, it is not clear how recruitment of these proteins to the Fas death domain leads to activation of caspase-8 in...

In studies on the induction of gene mutations by high energy radiation from the Bikini atom bomb, X-ray and other sources, a large number of seedling cultures have been grown for observation. Since January, 1949, maize seedling cultures have been observed by the use of filtered ultraviolet light. Normal seedlings viewed by ultraviolet light have a dull reddish-purple appearance due to the red f...

To better understand the mechanism of plastid differentiation from chloroplast to chromoplast, we examined proteome and plastid changes over four distinct developmental stages of 'Micro-Tom' fruit. Additionally, to discover more about the relationship between fruit color and plastid differentiation, we also analyzed and compared 'Micro-Tom' results with those from two other varieties, 'Black' a...

We present the DNA analyzer (DNASER), a novel bioinstrumentation for real-time acquisition and elaboration of images from fluorescent DNA microarrays. A white light beam illuminates the target sample allowing the images grabbing on a high sensibility and wide-band charge-coupled device camera (ORCA II-Hamamatsu). This high-performance device permits to acquire images faster and of higher qualit...
