Inductive signals across germ layers are important for the development of the endoderm in vertebrates and invertebrates (Tam, P.P., M. Kanai-Azuma, and Y. Kanai. 2003. Curr. Opin. Genet. Dev. 13:393-400; Nakagoshi, H. 2005. Dev. Growth Differ. 47:383-392). In flies, the visceral mesoderm secretes signaling molecules that diffuse into the underlying midgut endoderm, where conserved signaling cas...

BACKGROUND/AIM To compare estrogen and betamethasone in the topical treatment of labial adhesions in prepubertal girls. MATERIALS AND METHODS In this retrospective study, we evaluated 39 girls with labial adhesions covering at least 50% of the vaginal opening. Of the total patients, 20 were treated with a topical estrogen preparation, while the remaining 19 patients were treated with a combin...

This study is to use cone beam computed tomography (CBCT) to acquire accurate radiographic images for alveolar bone in lower incisors and the change after presurgical orthodontic treatment. Seventeen patients with skeletal Class III malocclusion, ten normal occlusion subjects, and fifteen patients treated with orthodontic treatment and orthognathic surgery were included. CBCT images were obtain...

Anuran larvae, which are otherwise simple in shape, typically have complex keratinized mouthparts (i.e. labial teeth and jaw sheaths) that allow them to graze upon surfaces. The diversity in these structures among species presumably reflects specializations that allow for maximal feeding efficiency on different types of food. However, we lack a general understanding of how these oral structures...

plan. We realize most of troubles occur when patients’ initial conditions were not analyzed accurately and exact diagnoses were not performed accordingly. As we start treating patients more and more, we build greater depth of knowledge on differentiating these troubles during diagnoses. These troubles mostly come from anatomical limitations, and these limitations are related to either soft tiss...

A labial biopsy technique is described and was used to study 40 patients with connective tissue disease and 60 postmortem subjects. More than one focus of lymphocytes per 4 sq mm of minor salivary tissue was found to be a consistent finding in patients with Sjögren's disease. The labial biopsy is shown to be a further valuable investigative procedure in such patients.

Introduction and Objectives: There has been an emergence of procedures to release the superior labial frenula in infants, yet little is known about the normal appearance or incidence of severe attachment, or "lip-tie." The objective of this article was to develop a classification system for superior labial frenula and to estimate the incidence of different degrees of attachment. Methods: A pros...

Labial gland secretions of 22 males of the bumblebee Bombus pomorum, collected in the Czech Republic, were analysed separately for each individual. The secretions contained 70 compounds among which saturated and unsaturated hydrocarbons strongly dominated. The proportion of hydrocarbons in the secretion was unusually high (85-100%) compared to other bumblebee species studied so far (3-15%). Met...

PURPOSE The midline fracture of maxillary complete dentures is a frequently encountered complication. The purpose of this study was to assess the effect of frenulum height on midline strains of maxillary complete dentures. MATERIALS AND METHODS A removable maxillary complete denture was fabricated and duplicated seven times. Four different labial frenulum heights were tested for stresses occu...
