Peripheral T-cell lymphomas are a group of heterogeneous disorders and according to WHO classification, are categorized into nodal and extranodal forms. NK/T-cell lymphoma, nasal type, is a subtype of extranodal peripheral T-cell lymphoma and commonly presents as a midfacial destructive lesion. This disorder is more prevalent in Asia and South America and has a strong association with Epstein B...

leiomyoma of nasal cavity is a rare and benign tumor of smooth muscle origin that uncommonly arises from the nasal septum. we present an unusual case of histopathologically diagnosed locally extensive leiomyoma of the nasal septum which was clinically and radiologically misdiagnosed as malignancy of the nasal cavity. this case report emphasizes the rare occurrence of this entity at this site an...

Plasmodium falciparum DNA, isolated from the merozoite stage, was cleaved with HindIII and cloned in pBR322 and lambda L47.1 vectors. Plasmid clones containing 13.4, 7.0, 4.3, 4.1 and 1.5 kb inserts were characterized in some detail. The inserts contain several repeating units of smaller size. Nucleic acid hybridization studies showed that the repeat element is present in the Plasmodium DNA at ...

A recently developed ultra-hard boride-based material, AlMgB14, has been fabricated into a standard cutting tool geometry (TPG-222) and tested using single-point turning of Ti-6Al-4V. The initial testing was conducted to compare this new cutting tool’s performance relative to a WC-Co cutting tool. During the tests the boride-based inserts suffered catastrophic failure for a wide range of cuttin...

introduction: neonatal period damages occur due to mechanical forces (compression, stretching) during the birth process are classified as birth trauma. various maternofetal factors, such as maternal diabetes, breech or other noncephalic presentations and birth weight might have been effective in developing prenatal trauma. shoulder dystocia, which is common in neonates` of diabetic mothers, usu...

introdouction: the mapping of ghost images of the maxilla and the nasal cavity, which are complex structures, is very important. the position of objects that create a ghost image can differ when using various devices. the purpose of this investigation was to study the mapping of ghost images of the maxilla and the nasal cavity using a cranex d digital panoramic machine. materials and methods: t...

acoustic analysis of sounds produced during speech provides significant information about the physiology of larynx and vocal tract. the analysis of voice power spectrum is a fundamental sensitive method of acoustic assessment that provides valuable information about the voice source and characteristics of vocal tract resonance cavities. the changes in long-term average spectrum (ltas) spectral ...

The purposes of this paper were to discuss the perceived benefits of inserts and orthotics for sport activities and to propose a new concept for inserts and orthotics. There is evidence that inserts or orthotics reduce or prevent movement-related injuries. However, there is limited knowledge about the specific functioning an orthotic or insert provides. The same orthotic or insert is often prop...

Introduction: Lobular capillary hemangioma (LCH) is a benign lesion of vascular origin. It rarely involves nasal cavity which most commonly manifests as progressive nasal obstruction and epistaxis. Case Report: In this report we present a case of LCH of the nasal cavity which occurred approximately one month after delivery. There was no recurrence after complete endoscopic resection during ...

Heat transfer enhancement is the process of increasing heat-transfer coefficient, which enhances system's performance. Enhancing heat a major problem for saving energy and also beneficial economically. Many passive devices are used inside tubes to improve such as twisted tape inserts, rough parts, extended surfaces, additives liquids wire plugs, etc. This research reviewed one most effective in...
