A survey of the literature is presented regarding the simulation of port wine stain (PWS) skin color. Knowledge of PWS features, such as the depths and diameters of affected vessels, is essential for informing laser treatment. These may be determined through the inverse application of a skin model. The techniques which have been applied to achieve this are analyzed in detail. Radiative transfer...

OBJECTIVE This study reports a new concept for quantitative analysis of velopharyngeal function using electromagnetic articulography and simultaneous transoral video endoscopy. PARTICIPANTS The velopharyngeal closure mechanism was studied in 16 healthy German subjects during production of the vowel-consonant-vowel sequences /afa/ and /apa/. DESIGN Velar movements in the sagittal and vertica...

This article describes a simple and inexpensive modem intended to link end users at 76.8kBit/s to the high speed backbone network. The modem can be connected to standard PC’s using the Enhanced Parallel Port (EPP) interface.

Accurate and rapid estimation of fluence, reflectance, and absorbance in multilayered biological media has been essential in many biophotonics applications that aim to diagnose, cure, or model in vivo tissue. The radiative transfer equation (RTE) rigorously models light transfer in absorbing and scattering media. However, analytical solutions to the RTE are limited even in simple homogeneous or...

 Hepatocellular adenomas (HCAs) are benign liver tumors recently characterized into 4 different types according to genetic, pathological and clinical features. The prognosis is not well established yet and malignant transformation has been recently associated with β-catenin activation. We aimed to describe a case of a pigmented HCA with β-catenin nuclear expression and inflammatory features and...

A 49-year-old farmer presented with papules on the face, arms, chest and back associated with sclerosis. Histopathology and PAS stain confirmed the clinical diagnosis of scleromyxedema. He also had elevated CPK levels due to myopathy. Screening for internal malignancy was negative.

Fig. 3. Wrinkled, white, moldy-appearing seed infected by Phomopsis spp. More than 30 fungi are seed-borne on soybeans. Some, such as Phomopsis spp., the cause of pod and stem blight disease, can severely reduce seed viability (fi g. 1). Others cause quality problems, such as purple seed stain, caused by Cercospora kikuchii, but have less severe effects on viability. However, most fungi that ar...

Methods and Results: Ethanol yield, residual sugar concentration, as well as glycerol a...

OBJECTIVE This study was performed to assess our clinical experience with single-port access (SPA) laparoscopic cystectomy and myomectomy and the surgical outcomes of those procedures at our institution. METHODS The authors evaluated the surgical outcomes of SPA laparoscopic cystectomy in 293 patients and SPA laparoscopic myomectomy in 246 patients. The surgical outcomes comprised operation t...

BACKGROUND AND OBJECTIVE Skin cooling is used to protect the epidermis in a variety of laser dermatology procedures, including leg vein treatment, hair removal, and port wine stain removal. Spray and contact cooling are the two most popular methods, but similarities and differences of these techniques are not well understood. STUDY DESIGN/MATERIALS AND METHODS A theoretical model of skin cool...
