OBJECTIVE To explore nasolabial movements in participants with repaired cleft lip and palate. DESIGN A parallel, three-group, nonrandomized clinical trial. SUBJECTS Group 1=31 participants with a cleft lip slated for revision surgery (revision), group 2=32 participants with a cleft lip who did not have surgery (nonrevision), and group 3=37 noncleft control participants. METHODS Three-dime...

LiP (lignin peroxidase) from Trametopsis cervina has an exposed catalytic tyrosine residue (Tyr181) instead of the tryptophan conserved in other lignin-degrading peroxidases. Pristine LiP showed a lag period in VA (veratryl alcohol) oxidation. However, VA-LiP (LiP after treatment with H2O2 and VA) lacked this lag, and H2O2-LiP (H2O2-treated LiP) was inactive. MS analyses revealed that VA-LiP in...

Accurately tracking facial features requires coping with the large variation in appearance across subjects and the combination of rigid and non-rigid motion. In this paper, we describe our work toward developing a robust method of tracking facial features, in particular, lip contours, by using a multi-state mouth model and combining lip color, shape and motion information. Three lip states are ...

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...

lip is an important aspect of facial features affecting ones personality. a deformity of the lip characterized by excessive tissue sagging below the usual giving it thicker wider appearance is referred to as double lip. it is a rare occurrence with a proposed male predilection. this article is a report of a 20 years old male with this deformity who presented with the complaint of difficult spee...

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...

Earlier diagnosis of oral cancer should lead to an improvement in prognosis. This, the second part of a two-part overview, is concerned with the various cellular markers available for diagnosis of oral cancer. Traditionally diagnosis has relied upon the histomorphological interpretation of a tissue section following biopsy. The application of advances in various laboratory techniques for the id...

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...

The incidence of oral cancer is increasing worldwide. Malignant neoplasms of the mouth and pharynx have been rated as the 10th most common cancer in men and 7th in women, though geographical variations exist.1Generally, in a society, oral cancer is not properly understood. The sign and symptoms are frequently overlooked in the initial stages when it is responsive to treat.
