Increasing the rate of neoplasms in industrial societies and its wide variety among ornamental and wild fishes in both fresh and salt waters are important. The effect of carcinogenic factors and the role of virus in tumor formation should be considered. In this study 10 3-month-olds Koi and Marble strains of fresh water Angelfish (Pterophyllum scalare), , with cauliflower lesions masses w...
Background & Aims: The aim of this study was to compare trapezius squeezing and jaw thrust to evaluate suitable conditions for laryngeal mask airway (LMA) insertion. Materials & Methods: In this clinical trial study, 138 patients with ASA physical status 1 or 2 who were candidates for elective surgery of shin fracture were randomly assigned into one of the groups of trapezius squeeze and raisi...
lipoma is the most common soft tissue tumor but the presence of osseous component within the tumor is quite rare. some studies show that less than 1% of lipomas were ossified. we describe the histological, radiological and diagnostic features of an ossified intramuscular lipoma. to the best of the authors' knowledge, a symptomatic ossified intramuscular lipoma without any cortical erosion and h...
Osteonecrosis of the jaw, in association with bisphosphonates (BRONJ) used for treating osteoporosis or cancer, is a severe and most often irreversible side effect whose underlying pathophysiological mechanisms remain largely unknown. Osteocytes are involved in bone remodeling and mineralization where they orchestrate the delicate equilibrium between osteoclast and osteoblast activity and throu...
BACKGROUND Intravenous bisphosphonate therapy has been used for treatment of benign and malignant bone diseases and has been linked to osteonecrosis of the jaws. METHODS Records of 638 patients treated with intravenous bisphosphonates were reviewed. Drug used, number of infusions, dosing interval, dosage, duration, and occasion of osteonecrosis, diagnosed by history and physical examination, ...
introduction: in open reduction and internal fixation for the treatment of mandibular fracture, the fixation technique used is very important in reducing post-operative complications and promoting the healing process. this study assessed the results of fixation of the mandible using two mini-plates perpendicular to each other in the lower border of the mandible for fracture treatment. materi...
Maximum jaw gape is a performance variable related to feeding and non-feeding oral behaviors, such as canine gape displays, and is influenced by several factors including jaw-muscle fiber architecture, muscle position on the skull, and jaw morphology. Maximum gape, jaw length, and canine height are strongly correlated across catarrhine primates, but relationships between gape and other aspects ...
The effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) exposure on regional red blood cell (RBC) perfusion rate, as an index of blood flow, and lower jaw development were investigated quantitatively in zebrafish embryos (Danio rerio) during early development. As revealed by observation of live embryos and alcian-blue staining, TCDD retarded lower jaw development in a concentration-dependent ...
Seven specimens of Paloa villadolidi Roxas and Ablan, 1940, were collected from Okinawa Ishigaki islands in the Ryukyu Archipelago, Japan, their morphologies are described herein. Although this species has been considered as a synonym Odonteleotris macrodon (Bleeker, 1853) which is redescribed study, former distinguished latter by having steeper jaw (upper tip not reaching orbit vs. ending belo...
