PURPOSE One of the most common problems of the surgical management of Graves upper eyelid retraction is the occurrence of eyelid contour abnormalities. In the present study, the postoperative contour of a large sample of eyelids of patients with Graves orbitopathy was measured. METHODS The postoperative upper eyelid contour of 62 eyes of 43 patients with Graves orbitopathy was subjectively cl...

We present a method for fully automatic segmentation of the bones and cartilages of the human knee from MRI data. Based on statistical shape models and graph-based optimization, first the femoral and tibial bone surfaces are reconstructed. Starting from the bone surfaces the cartilages are segmented simultaneously with a multi object technique using prior knowledge on the variation of cartilage...

The cephalic and pectoral girdle structures of the Chinese catfish Cranoglanis bouderius are described and compared with those of other catfishes as the foundation for an analysis on the Cranoglanididae autapomorphies and also for a discussion on the phylogenetic relationships between the cranoglanidids and the other catfishes. Our observations and comparisons indicate that cranoglanidids are d...

The study presents the first attempt to investigate resonance properties of the living vocal folds by means of laryngoscopy. Laryngeal vibrations were excited via a shaker placed on the neck of a male subject and observed by means of videostroboscopy and videokymography (VKG). When the vocal folds were tuned to the phonation frequency of 110 Hz and sinusoidal vibration with sweeping frequency (...

The phenotypes of skeletal malformations induced in pharyngeal arches and pectoral fins of Ž . X Japanese flounder larvae by retinoic acid RA , disulfiram, 2,2 -dipyridyl and azetidine-2-carboxylic acid were characterized, RA controls gene expression essential for pharyngeal and pectoral fin development; disulfiram is an inhibitor of RA synthase, 2,2-dipyridyl and azetidine-2-carboxylic acid ar...

An understanding of the interrelationships between cells and the intercellular substance of cartilages may help resolve the question of why some cartilages ossify and others do not. Thus far, in autoradiograms of growing bones, S%ulfate has been seen concentrated initially in chondrocytes (l-3), from which it is extruded into the matrix (1)) and thence, a portion of the label persists in the bo...

Both functional and cosmetic rhinoplasty in the elderly require a different surgical approach due to the morphological and structural changes of the nose that are connected to the aging process. Such processes determine changes of all anatomical structures that form the aesthetic-functional unit. In particular thinning of the skin envelope becomes apparent with pores dilatation and increased se...

abstract purpose: skeletal staining is a way to study the effect of many chemical or herbal substances on development of bones and cartilages in order to record the level of probable deformity.this article aimed to present a modified protocol to make all skeletal studies on laboratory animals possible. materials and methods: the important notes about skeletal staining were fixing by ethanol and...

OBJECTIVE To describe a new physical finding called involutional lateral entropion (ILE) of the upper eyelid found in Asian patients. METHODS A prospective case series study of 53 consecutive patients with ILE of the upper eyelid, from the practice of one of the authors (J.G.C.), was performed. All of the patients in this series were Asian. Clinical findings on ocular examination, symptoms, a...

UNLABELLED The purpose of this research was to examine the distribution of the tooth size in a large sample. The objective teeth were the left upper and lower fourteen teeth except the third molar. The tooth size of 1,000 dental casts from the Japanese female orthodontic patients was measured. On each of them, a histogram and a set of statistics (mean, standard deviation, coefficient of variati...
