OBJECTIVE To better characterize the dermoscopic patterns of mucosal lesions in relation to the histopathologic characteristics. DESIGN Retrospective and observational study. SETTING Fourteen referral pigmented lesion clinics in 10 countries. PATIENTS A total of 140 pigmented mucosal lesions (126 benign lesions, 11 melanomas, 2 Bowen disease lesions, and 1 metastasis) from 92 females (66%...

BACKGROUND Previous studies have shown that the human circadian system is maximally sensitive to short-wavelength (blue) light. Whether this sensitivity can be utilized to increase the size of phase shifts using light boxes and protocols designed for practical settings is not known. We assessed whether bright polychromatic lamps enriched in the short-wavelength portion of the visible light spec...

Protected areas (PAs) on tropical mountains undergo greater forest destruction in their lower altitudes. We compared the extent of forested, nonforested, and fragmented areas between lowland (o 1000 m asl) and montane zones of the Blue Mountains inside the Blue and John Crow Mountains National Park established in Jamaica in 1993. We found that in 2008, inside the montane zone, only 4 percent of...

Methylene blue (MB) is a cationic thiazine dye with the chemical name tetramethylthionine chloride. It has a characteristic deep blue color in the oxidized state, but the reduced form, leukomethylene blue (LMB), is colorless. Methylene blue has been widely used in a variety of clinical settings to identify anatomic (Manhes et al., ’94; Sills and Zinkham, ’94; Barber et al., ’95) and pathologic ...

A soluble viral antigen with possible diagnostic utility was obtained from blue-tongue virus-infected lamb kidney cells. It is a noninfectious proteinaceous substance without nucleic acid. The antigen is immunologically identical to one component of the viral particle, and in agar-gel diffusion tests it reacted with antiserum against several blue-tongue virus strains.

Electrostatic interactions between an ESIPT molecule 2-(5'-amino-2'-hydroxyphenyl)benzothiazole (AHBT) and a phenylborate derivative give blue-green emission in acetic acid solution, but interestingly, vigorous (or mechanical) shaking of the solution leads to the formation of organic AHBT nanoparticles, which results in fluorescence colour switching from blue-green to yellow-orange.

This paper outlines the process involved in designing and developing an online staff development resource in cross-cultural awareness. The project serves as an example of collaboration between the central Human Resources department, and educational and technical staff within the Flexible Learning Unit at Griffith University.
