Cutaneous horn is a horn-like keratotic lesion, which commonly occurs on the head and face, over a wide range of benign or malignant skin lesions. Callosity is a hyperkeratotic plaque produced by intermittent or continuous pressure on the skin. Lateral aspects of the ankles (Lateral malleoli) are frequently involved. We report a rare case of cutaneous horn developed on ankle callosity.

The swimming movements of C. gariepinus larvae were recorded with a high-speed camera (400, 500 and 800 fps) from 0 to 336 hours post-hatching. Movements of adult fish were also recorded to provide information on the last developmental stage. Seven landmarks positioned on the fish midline were used during tail beating to determine various parameters during ontogeny and, on the basis of these pa...

A new species of Brycon is described from the Atlantic slope of Nicaragua and Costa Rica. Brycon costaricensis n. sp. differs from all other Central American Brycon species by the following combination of characters: 49 to 54 scales in the lateral line; 5 or 6 rows of scales between lateral line and pectoral fin base; 9 to 11 rows of scales between lateral line and dorsal fin base; 5 to 7 rows ...

The objective of this research is to develop neck injury criteria and injury tolerance levels to be used as a basis for a performance standard for the certification of side facing aircraft seats. This paper presents the results of the first part of this study. A literature review was performed on the neck injuries, kinematics and injury mechanisms in lateral loading and existing injury criteria...

Pediatric elbow fractures can be challenging to manage. Compression of the medial column in Gartland Type I and Type II supracondylar fractures must be reduced to prevent varus deformity. Gartland Type III fractures may be stabilized with two lateral pins or a medial lateral cross-pin technique. Non-displaced lateral condyle fractures require vigilant follow-up. Open reduction of displaced late...

to identify the faunal parasitic nematodes of mazandaran, guilan and ardebil provinces, roughly 30 soil samples were collected from the rhizosphere of forest trees during 2005-2009. nematodes were extracted from soil through centrifugal flotation technique. the extracted nematodes were transferred to pure glycerin using common methods. permanent slides were made and nematodes identified as base...

The accuracy of measurement of tooth length and angulation on dental panoramic tomograms (DPTs) is thought to be highly dependent on head positioning technique. A model representing the dentition and the functional occlusal plane was designed using an acrylic framework and stainless steel wires. The aim was to investigate whether varying the position of the model affects the linear and angular ...

Astyanax pirabitira, new species, is described from the upper portion of the rio das Antas, laguna dos Patos system, and from the rio Pelotas, upper rio Uruguay drainage, Rio Grande do Sul State, Brazil. The new species belongs to the A. scabripinnis species complex and differs from its congeners by a combination of characters, viz., body depth (27.1-34.0% of standard length), narrow interorbit...

The 1,000 soldiers in this study were consecutive, non-selected cases who were sent to the roentgen (X-ray) department because of a low back complaint. By using their meticulous methodology of measurement, these authors conclude it is possible to accurately measure differences in lower extremity lengths as manifested by a difference in the heights of the femoral heads. The greatest difference i...
