Measurements were taken from 18 patients operated on for cleft lip and palate, aged 19 to 27 years, and 162 control subjects matched for sex, age, and ethnic group. Nine soft-tissue landmarks on the lips were digitized by a three-dimensional electromagnetic instrument. From the landmarks, several linear distances (mouth width, philtrum width, vermilion height of upper and lower lip, total vermi...

This paper presents a new lip detection method based-on normalized RGB chromaticity diagram. The method consists of three stages: face detection, lip region localization and lip detection. The popular Viola-Jones face detection technique is employed in the face detection stage. In the lip detection stage, lip color is extracted using our novel color segmentation method that exploits the distrib...

In this study, harmine liposomes (HM-lip) were prepared through the thin-film hydration-pH-gradient method and then coated with N-trimethyl chitosan (TMC). Particle size, zeta potential, entrapment efficiency, and in vitro release of HM-lip and TMC-coated harmine liposomes (TMC-HM-lip) were also determined. Sprague Dawley rats were further used to investigate the pharmacokinetics in vivo. Reten...

Visual information from lip shapes and movements helps improve the accuracy and robustness of a speech recognition system. In this paper, a new region-based lip contour extraction algorithm that combines the merits of the point-based model and the parametric model is presented. Our algorithm uses a 16-point lip model to describe the lip contour. Given a robust probability map of the color lip i...

LOU M/Wsl rats inoculated s.c. with 10(4) immunoglobulin immunocytoma cells have a palpable tumor at Day 17. Doxorubicin (DXR) has been entrapped in negatively charged liposomes (lip- DXR) composed of egg phosphatidylcholine, cholesterol, and phosphatidylserine and in positively charged liposomes (lip+ DXR) composed of phosphatidylcholine, cholesterol, and stearylamine. DXR, lip- DXR, and lip+ ...

BACKGROUND The Millard method of unilateral cleft lip repair has been associated with a short lip and a flattened nose on the cleft side. The aim of this study was to determine the need for revision surgery following repair of unilateral cleft lip repair at the Komfo Anokye Teaching Hospital. METHOD Satisfaction with facial appearance (upper lip, nose and general facial appearance) was assess...

BACKGROUND An intimidating challenge to transporting drugs into the brain parenchyma is the presence of the blood-brain barrier (BBB). Glucose is an essential nutritional substance for brain function sustenance, which cannot be synthesized by the brain. Its transport primarily depends on the glucose transporters on the brain capillary endothelial cells. In this paper, the brain-targeted propert...

In this study, we aim to understand the morphology and structure of upper lip orbicularis oris muscle, and to provide clinical evidence for evaluating the effect of repair operation in cleft lip. Subjects included 106 healthy people and 36 postoperative patients of unilateral cleft lip. The upper lip orbicularis oris muscle was scanned using ultrasound in natural closure and pout states. Our re...
