The cephalic labial gland secretion of Bombus semenoviellus males was analyzed, and its chemical composition is reported for the first time. The secretion functions as sex or marking pheromone. Eighty compounds were identified in the secretion, the main one being all-trans-geranylgeranyl acetate (48%). The same compound was shown to form 87% of the labial gland secretion of B. cullumanus males....

Secretions of three different glands (mandibular gland, labial gland, and Dufour's gland) of virgin queens of five bumblebee species (Bombus lucorum, B. lapidarius, B. hypnorum, B. pascuorum, and B. terrestris) were analysed. Around 200 compounds were identified in the secretions. The compositions of the secretions of labial and mandibular glands were species-specific. Dufour's gland of all spe...

The labial thermistor clip was first introduced as a physiological measure of female sexual arousal almost 30 years ago (Henson, Rubin, Henson, & Williams, 1977); however, only a few studies have subsequently reported on its use. The development of the clip was based on the idea that surface temperature reflects changes in blood volume such as what causes genital tumescence during physiological...

Resection of buccal mucosa tumors may occasionally involve the labial angle and peripheral skin. Reconstruction is required when the resection involves more than one-third of the lip. We describe a single-stage reconstruction using a facial artery musculomucosal (FAMM) flap and a vermilion advancement flap after buccal mucosa resection including the labial angle. A 62-year-old woman with carcin...

This paper presents SEM micrographs of portions of the male, female, and infective-stage juvenile of Steinernema anomali. Included are micrographs of the cephalic and caudal region, spicules, and gubernaculum of the male, the cephalic and vulval region of the female, and the cephalic region of the infective-stage juvenile. Males have six labial and four prominent cephalic papillae and small amp...

Our work deals with the classical problem of merging heterogenous and asynchronous parameters. It's well known that lips reading improves the speech recognition score, specially in noise condition ; so we study more precisely the modeling of acoustic and labial parameters to propose two Automatic Speech Recognition Systems : a Direct Identi cation is performed by using a classical HMM approach ...

X-ray microanalysis of freeze-dried labial gland cryosections revealed that Na concentration was doubled and the Ca/S concentration ratio was decreased in secretory granules of labial glands from patients with cystic fibrosis (CF) when compared with glands from normal subjects. Other results suggested that the decrease in the Ca/S concentration ratio resulted from an increase in S concentration...

Margollus turcicus sp. n., is described and illustrated from vineyard soil in Turkey. The new species is characterized by having a medium sized body (L=1.0-1.2 mm); cuticle with distinct striations; radial refractive elements abundant; lip region distinctly narrower than the adjoining body and slightly offset from the body contour by a depression; cephalic and labial papillae not discernible; s...

In bumblebees, the male secretion of the cephalic labial gland is species-specific. It is highly involved in the nuptial behavior, acting as a sexual attracting pheromone. Therefore, it is also used to accurately identify the species. In contrast to this common scheme, the secretions of Bombus mesomelas are found to be strongly reduced and do not include the most volatile compounds that are pre...

In the maxillary anterior region, the gingival labial margin position is an important parameter in the achievement of an ideal smile. The relationship between the periodontium and the restoration is critical if gingival health and esthetics are to be achieved. Periodontal therapy is a necessary and useful adjunct when any anterior restoration is undertaken. Anterior surgical crown lengthening m...
