High frequency ultrasound assessment of labial glands simulating small nodules or granulomas after lip augmentation

Introduction Lips are a very important part of facial attractiveness. From time immemorial, mainly women have enhanced their lips as an indication of youth, beauty and sensuality(1,2). Ideal lips are full with well-defined vermilion border. Passage of time and the associated subcutaneous adipose tissue atrophy, loss of elasticity, effects of gravity and the remodelling of the skeleton and muscles lead to the ageing of this area. Beginning in the third decade of life, internal factors such as

lips. B: Lateral view. C: Face view showing a male with just four lips. D: Medial view showing a male with six distinct lips. In the light microscope, the male is very long and tapered in the head region and has a rounded tail that is twisted 90° in relation to the rest of the body. The dome-shaped head cap is set-off from the regular body annulation. The labial disk is distinctly concave and separated from the lips. SEM revealed that some males contain a full complement of six smooth, rounded

Morphological Re-Description and 18 S rDNA Sequence Confirmation of the Pinworm Aspiculuris tetraptera (Nematoda, Heteroxynematidae) Infecting the Laboratory Mice Mus musculus

Aspiculuris tetraptera is a heteroxynematid nematoda infecting most of the laboratory animals, occasionally mice which represent the mostly used animal for biological, medical, and pharmacological studies. The present study aimed to investigate the prevalence of nematode parasites infection in the laboratory mice Mus musculus in Egypt. Morphologically, this oxyurid possessed four distinct cephalic papillae on a cephalic plate, with three small rudimental lips carrying two sessile poorly

terminal, near the anus. Vulval lips are pronounced with protrusion. Vulva-anus region is slightly concave to flat (Fig. 3B). Mature females contain less than 100 eggs in various stages of development. Perineal patterns are difficult to prepare flat due to a prominent protuberance. Perineal pattern is ovoid with fine, smooth and continuous striae. Vulva is surrounded by circles of striae (Fig. 3C). Male Not found. Second-stage juvenile (J2) The body is cylindrical, tapering posteriorly, straight or

Gracilacus paralatescens n. sp., isolated in Anji County, Zhejiang Province, China from the rhizospheric soil of bamboo. The new species can be characterized by the female lateral field with three incisures, stylet 71.5 to 78.8 µm long, lip region truncated, excretory pore located anterior to basal knobs. Vulval lips non-protruding and without vulval flap, spermatheca large, elongated squarish shaped filled with sperms. Tail slender, relatively straight having wedge shape terminus. The spicule

prominent annuli 1.0 to 1.5  µm wide varying with body regions. Lateral fields were indistinct under light microscopy; however, four longitudinal lines are visible under scanning electron microscopy. The Lip region was almost continuous from contiguous body. Lips rounded and swollen, organized in doublets forming three pairs (one dorsal and two subventral) around the triradial oral orifice. Amphids small, oval, positioned at the base of lateral lips. Stoma rhabditoid type, 1.5 to 3.4 times the lip

. Oviduct is comparatively longer, connecting ovary and spermatheca. Spermatheca is round or oblong, containing round sperm, present in majority of specimens. Uterus is thick-walled. Vagina wall is parallel not sclerotised, vulva pore shape, and lips simple without flap. In some specimens, vulval region appears sunken. PUS is well developed, extending for ca 44.5 to 82.7% of vulva to anus distance. Rectum and anus are visible. Tail is straight, cylindrical, ca 2.7 times longer than anal body diam. Tail

A study of Class III treatment: orthodontic camouflage vs orthognathic surgery

incisors were less retroclined in the surgery group. There was a small mean reduction in horizontal chin projection in the surgery group compared with a small increase in the camouflage group. The mentolabial fold and the lower lip curve were deeper, on average, and the lips less retrusive after surgery. There was a mean increase in upper incisor proclination during treatment in both the surgical and camouflage groups with a greater increase in the camouflage group. There was a significant reduction in
