BACKGROUND/PURPOSE The skin plays an important role as a protective barrier against toxic environments and also is a route of drug administration. In spite of evidence for and interest in the skin penetration of nanoparticles, no study has examined the effect of nanoparticle surface charge on percutaneous absorption. In this study, we investigated the(More)
BACKGROUND/PURPOSE Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disorder that is becoming increasingly prevalent. Experimental animal models have been an indispensable tool for studying its pathological mechanisms and for in vivo testing of novel therapeutic approaches. AD-like lesions can be induced experimentally in NC/Nga mice.(More)
BACKGROUND/AIMS The objective and quantitative assessment of the skin is important in medical and cosmeceutical research. Assessment of color is an important element for analyzing the surface of the skin, which is usually determined subjectively by a doctor or using color analysis devices. These devices, however, cannot provide correct color information(More)
BACKGROUND Dermoscopy is a non-invasive in vivo skin imaging technique that assists dermatologists in diagnosing melanoma. However, the use of dermoscopy for diagnosis requires extensive training since this approach often provides extremely complex and subjective information. The presence of an imperceptible color difference in dermoscopy images is one of(More)
Onychomycosis, or fungal infection of the nail, is a disease seen frequently in clinical settings. However, the rates of positive identification using potassium hydroxide preparations or fungal cultures are relatively low. Precise diagnosis is possible via histopathologic examination to monitor the existence of fungus and performance of a fungal culture for(More)
Oregonin has been reported to act as a mediator of antibiosis, a liver-protective agent, an antioxidant, an anti-inflammatory agent, and to prevent cancer outbreaks. B16 melanoma cells were separated with trypsin-ethylenediaminetetraacetic acid, resuspended in 50 μl of phosphate-buffered saline and transplanted into the backs of 6- to 8-week-old male Balb/c(More)
BACKGROUND/PURPOSE The visual scoring method has been used as a subjective evaluation of pigmentary skin disorders. Severity of pigmentary skin disease, especially melasma, is evaluated using a visual scoring method, the MASI (melasma area severity index). This study differentiates between epidermal and dermal pigmented disease. The study was undertaken to(More)
BACKGROUND/PURPOSE The aim of this study was to establish a scientific assessment method to evaluate the severity of atopic dermatitis (AD) by calibrating part of a previously described stereo-image optical topometer (SOT). METHODS The old SOT was created using a non-convergence model. However, this study utilizes a convergence model. Camera calibration(More)
Early diagnosis is one of the most important factors that increase the therapeutic potential of the disease. Diagnoses conducted by conventional equipment are expensive, time-consuming, burdensome to patients, and do not have high success rates. Diagnostic methods have also been investigated using nanoparticles. However, there have been no significant(More)
BACKGROUND There are several available treatments for vitiligo, but measurement of their therapeutic efficacy is not standardized and is somewhat arbitrary based largely on the global impression of the overall response. The purpose of this study was to develop a quantitative method for evaluating the treatment response of vitiligo measuring changes in area(More)
