“…Principal contents of the orbits include the eyeballs, extraocular muscles, orbital fat, nerves and blood supply, and lacrimal glands. Variation is evident in the size and morphology of the orbital apertures, as well as in the shape of the cavities, the foramina and grooves within them, and the individual bones of which the orbits are comprised (Adachi, 1904b;Pan, 1933;Woo, 1937-38;Schultz, 1940;Ray, 1955;Riesenfeld, 1956;Kier, 1966;Post, 1969;Ossenberg, 1970;Warwick, 1976) The growth of the eyes follows the rapid pattern of neural growth, although slower than the brain, and this is reflected in the relatively large size of the orbits in infants and children (Todd et al, 1940;Moore and Lavelle, 1974). Up until the expansion of the maxilla which accompanies the development of the permanent dentition, the orbits dominate the facial skeleton.…”

Globally there was a reduction in the size and robusticity of the human orofacial skeleton and dentition after the Pleistocene. There was also diachronic change in brain size and skeletal mass in general. Anthropologists have developed numerous models in explanation of the evolutionary process, with the majority linked to the cultural developments of the Neolithic. These cultural models are challenged by the skeletal evidence from societies with contrasting culture histories. In China there is a reduction in facial breadth, height and prognathism, posterior tooth size, brain volume and cranial robusticity from the Neolithic to the modern period. However, the height of the orbits increases rather than decreases. Examination of the structural relationships between orbit and facial dimensions in Tohoku Japanese and Australian Aboriginal crania suggests a steady reduction in orbit volume in China. This may have resulted in a more anterior placement of the eyeball and associated structures in modern East Asians than in their Neolithic counterparts.

“…It has been recommended to consider a 2-mm distance between the implant and the margin of the mental foramen. [2] Mental foramen is located on the anterolateral aspect of the body of mandible, lateral to and above the mental tubercle. It is felt as a slight depression .It gives passage to the mental nerve and vessels.…”

Background: The aim of this study was to investigate the most common accurate position of the mental foramen in selected Kashmiri population, which helps in several clinical procedure and nerve block anesthesia. Methods: The study sample included one thousand panoramic radiographs of selected population of Kashmir that presented to postgraduate department of oral and maxillofacial surgery, Govt. dental college and hospital Srinagar from 2008 to 2015. Results: The most common Horizontal position of the mental foramen was below the root of second premolar tooth i.e. position 4 (44.77%). Conclusion: This may help the clinicians and anthropologists in identifying the mental foramen more accurately.

“…The mental nerve emerges at the MF and divides into 4 branches: the angular branch (the innervation of the angle of the mouth), the medial and lateral inferior labial branches (the skin of the lower lip, oral mucosa, and gingiva as far posterior as the second premolar), and the mental branch (the skin of the mental region) (2). The presence of small foramina identified as accessory mental foramina (AMFs) in the surrounding area of the mental foramen has been discovered (3,4). The AMFs are defined as smaller buccal foramina with continuity to the mandibular canal (MC).…”

A new sildenafil analogue was found to have been added illegally to a dietary supplement marketed for the enhancement of sexual function. The structure was determined as 5- (2-ethoxy-5-{[4-(3,5-Owing to the inclusion of a dimethyl group in acetildenafil, the detected compound was called dimethylacetildenafil. The sample was purified with column chromatography. The IR, LC/MS (ESI), and completely assigned NMR data of dimethylacetildenafil are reported for the first time. The structure was compared with that of acetildenafil and the results showed that the ethyl substitution at the 4-position of the piperazine ring had been replaced by a 3,5-dimethyl substitution. This new acetildenafil analogue was isolated and identified for the first time.
