Arteriovenous malformations are extremely rare conditions in that can result from abnormalities in the structure of blood vessels, which may be potentially fatal. A 30-year-old female patient visited our hospital with a complaint of swelling on the right maxillary posterior gingiva along with the large port-wine stain on right side of face. On clinical examination, the swelling was compressible...

An evaluation of the standardised Romanowsky stain of Marshall et al. has been made in a routine haematology laboratory. It was noted that this stain had several advantages over the May-Grünwald Giemsa stain used in most British laboratories. These advantages include ease and speed of preparation, a shorter staining time, and reproducibility of results. These results are described in detail. Th...

BACKGROUND Antioxidant enrichment of LDL can increase its resistance to oxidation and hence reduce its atherogenicity. The objective of the present study was to investigate whether in vivo supplementation with nonalcoholic red wine extract and quercetin can increase the oxidative resistance of LDL, and also whether the supplementation has any effect on other antioxidative micronutrients present...

Abstract — Input queueing is becoming increasingly important for high-bandwidth switches and routers. In previous work, we proved that it is possible to achieve 100% throughput for input-queued switches using a cell-by-cell scheduling algorithm called LQF. However, LQF is too complex to implement in hardware. In this paper we introduce a new algorithm called Longest Port First (LPF), which is d...

Figure 1. Hematoxylin and eosin stain demonstrates a well-circumscribed dermal nodule (arrow) composed of mixed solid cellular proliferation including microcysts, ducts, and areas of myxoid stroma.

BACKGROUND Green stain is an uncommon clinical condition associated with deposition of bilirubin in the dental hard tissues. The staining of the teeth is due to hyperbilirubinemia caused by systemic conditions. CASE REPORT The purpose of this report is to present a case of green teeth of the primary dentition in a 17-month old girl associated with hydrocephalus and Hirschprung's disease. CO...

We describe a phase-resolved functional optical coherence tomography system that can simultaneously yieldin situ images of tissue structure, blood flow velocity, standard deviation, birefringence, and the Stokes vectors in human skin. Multifunctional images were obtained by processing of analytical interference fringe signals derived from two perpendicular polarization-detection channels. The b...

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...

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...
