For many years, speech has been the most natural and efficient means of information exchange for human beings. With the advancement of technology and the prevalence of computer usage, the design and production of speech recognition systems have been considered by researchers. Among this, lip-reading techniques encountered with many challenges for speech recognition, that one of the challenges b...

BACKGROUND Unwanted hair is a widespread cosmetic problem. Several lasers and intense pulsed light (IPL) have been utilized for this purpose. A new IPL device (Lumenis One) with OPT is one of the newer modalities to be studied in Chinese patients. OBJECTIVE This study evaluates the short-term efficacy and side effects of the new IPL device for epilation in Chinese patients. METHODS Eighteen...

The use of visual information from lip movements can improve the accuracy and robustness of a speech recognition system. Accurate extraction of visual features associated with the lips is thus very important. In this paper, we present a deformable model-based technique for lip contour extraction from color lip images. The geometric lip model we proposed is able to fit different lip shapes. Our ...

Lip contour detection and tracking is the most important pre-requisite for computerized speech reading. Several approaches have been proposed for lip tracking after lip contour is accurately initialized on first frame. Detection and tracking of the lip contour is an issue in speech reading. A relatively large class of lip reading algorithms are available based on lip contour analysis. In these ...

The purpose of this study was to determine the upper lip by Holdaway’s method in individuals with bimaxillary proclination and to find out correlations of skeletal convexity at point A & maxillary incisor inclination with upper lip inclination and upper lip strain. Lateral cephalograms of 100 patients (50 males and 50 females) exhibiting bimaxillary dental proclination were exposed in closed li...

objective(s)cpg oligodeoxynucleotides (cpg odns) have been shown to have potent immunostimulatory adjuvant activity for a wide range of antigens. due to susceptibility of phosphodiester cpg odns (po cpg) to nuclease degradation, nuclease-resistant phosphorothioate cpg odns (ps cpg) were currently utilized in an in vivo model. in this study, according to some recently reported drawbacks with ps ...

OBJECTIVE To compare the injection pain and speed of local anesthetic effect induced by tissue infiltration of mepivacaine 2% with epinephrine 1:100,000 versus articaine 4% with epinephrine 1:100,000 in securing mandibular first molar pulp anesthesia. MATERIALS AND METHODS Totally, 25 patients were recruited in a crossover, randomized, double-blind study. Each subject received injections of m...

BackgroundCleft lip and cleft palate (also, known as or facial clefts), are amongst the most common congenital deformities affecting the jaw and face as well as the most common defects associated with lip and palate. Thus, the current study was an attempt to investigate the prevalence and risk factors of or facial clefts in Iranian children.Materials and Methods:The present study, was conducted...

Introduction: Cleft lip and palate is a congenital anomaly occurring in 3 in 1000 live birth. One the major concern in this patient is about cleft gap and its surgical problems. Several surgical and non-surgical procedures have been done to decrease this gap. They aimed to achieve the more esthetic results as well as feeding success. Nasoalveolar Molding (NAM) is a new method for reshaping nasa...
