The nematode Binema bonaerensis n. sp. (Oxyurida: Thelastomatidae) is described from the intestine of the mole cricket of Neocurtilla claraziana Saussure (Orthoptera: Gryllotalpidae) from Buenos Aires Province, Argentina. It is distinguished mainly by having a conical tail; three sclerotized arches in the buccal cavity; an excretory pore immediately posterior to the base of the esophagus and th...

Midfacial degloving is a well-known technique for entering the nasal and paranasal cavities, the rhinopharynx and the base of the skull. We report our experience with a modification of midfacial degloving, applied to two patients with extensive bilateral benign tumours in the nasal cavities and the paranasal sinuses. No rhinoplastic procedure is necessary in this modification, and the access to...

Extreme resorption of edentulous maxilla may cause difficulty during fabrication of a maxillary complete denture. Increased inter-ridge distance often creates a clinical problem due to heavy-weighted maxillary prosthesis. This article elaborates an alternative approach for hollowing a maxillary complete denture. It utilizes a clear template of the trial denture facilitating the creation of a ge...

In this work, the stencil adaptive method is applied to investigate the effects of a magnetic field on mixed convection of Al2O3-water nanofluid in a square lid-driven cavity. The incompressible Navier-Stokes equations are solved by an adaptive mesh method which has superior numerical advantages compared to the traditional method on the uniform fine grid. The main objective of this study is to ...

UNLABELLED Lymphoma of the tongue is very rare and accounts for 1% of all malignant tumors of the oral cavity. We present a patient who presented with weakness and difficulties with ambulation who was a known cervical spine spondylosis and stenosis patient. During the preoperative workup for cervical spine surgery a tumor at the base of the tongue was discovered which was confirmed by pathology...

The title compound, [Cu(C(20)H(20)N(2)O(2))], crystallizes with two independent mol-ecules in the asymmetric unit. In each mol-ecule, the Cu(II) atom occupies the tetra-dentate N(2)O(2) cavity of the salen-type Schiff base ligand, adopting a distorted square-planar geometry with r.m.s. deviations of the coordin-ating atoms of 0.0522 (2) and 0.1128 (4) Å. No hydrogen bonds or π-π stacking inter-...

INTRODUCTION Intranasal meningoceles occur as a result of herniation of the meninges into the nasal cavity through a defect in the cribriform plate. These are commonly found in the pediatric population due to a congenital defect in the skull base. Intranasal meningoceles are very rare in adults, and tend to arise only when engendered by trauma. Here, we present the case of a patient with seemin...

We demonstrate self-seeded generation of a broadband comb in a highly nonlinear fiber resonator. When pumped with a cw laser, the fiber cavity generates a comb with two characteristic spacings. Hyperparametric modes spaced by approximately 2 THz create the base structure of the comb, while commensurate Brillouin modes spaced by approximately 10 GHz populate the intermediate frequency gaps. The ...

Herein the author presents a case of esthesioneuroblastoma, a rare malignancy affecting the sinonasal cavity. This uncommon lesion is thought to originate from the olfactory neuroepithelium. The mass may invade the orbit and intracranial space, and may metastasize to the neck or to distant sites. This case was successfully treated with an endoscopic craniofacial resection, multilayer skull base...

The anterior two thirds of the tongue lie in the oral cavity (mobile tongue). The posterior third (base of tongue) is in the oropharynx and the junction between the two is at the insertion of the anterior faucial pillar and the line of the circumvallate papillae. Eighty-five per cent of tumours arise on the lateral border of the oral tongue, 10 to 15% on the ventral surface and 5% or less from ...
