The modern orthopaedic implants for applications in hips, knees, shoulders, and spines are composed of hard metal alloys or ceramics a tribological sub-component that is made soft materials, with good frictional properties—e.g., UHMWPE (Ultra High Molecule Weight Polyethylene). need to be machined into their final shape after the polymerization consolidation blank profile near net shaped implan...

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...

introduction: to evaluate the most sensitive symptom to predict early recurrence of nasal polyposis. prospective longitudinal cohort study. tertiary university referral center with accredited otorhinolaryngology residency programs.  materials and methods: in this prospective study, we evaluated 62 patients with diffuse nasal polyposis. all patients underwent functional endoscopic sinus surgery....

Abstract: Background: Medication package inserts (MPIs) provides patients with appropriate information on the rational use of drugs. This study evaluated level conformity MPIs regulatory drug labelling requirements and determined readability selected prescription MPIs. Methods: One hundred fifty-six commonly used prescribed antilipidemics, anticonvulsants, anti-diabetes, antiarthritis antihyper...

Although various techniques have been described for treatment of severe nose deformities, these problems have high revision rates.  Conventional nasal septal surgery may not be adequate for all cases. A 21-year-old male patient with nose deformity underwent a nasal surgery. Patient had both functional and aesthetic nasal problems. Rigid fibular bone graft was used for corrective nasal ...

Background and Objective: Septoplasty is one of the most common nasal surgeries. After septoplasty, the nasal pack is routinely used to control bleeding, which can lead to complications such as pain and anxiety. This study aims to compare the effect of septoplasty with and without nasal packing on outcomes and complications of the surgery. Materials and Methods: In this randomized clinical tri...

In this study we explore the cutting performance of ZrAlN coatings. WC:Co cutting inserts coated by cathodic arc evaporated Zr1-xAlxN coatings with x between 0 and 0.83 were tested in a longitudinal turning operation. The progress of wear was studied by optical microscopy and the used inserts were studied by electron microscopy. The cutting performance was correlated to the coating composition ...

We report on the structure of the small-subunit ribosomal RNA (18S rRNA) sequence from Hyptiotes gertschi (Araneae, Uloboridae), which is the largest 18S gene sequenced in any arachnid to date. We compare this remarkable sequence to those from a range of other spiders and arachnids, and develop base-pairing models of its insert regions to determine its overall secondary structure. The H. gertsc...
