Background: As increase of cytokines (like IL-1 , IL-6 , IL-8 and TNF- ) in platelet concentrates (PCs) during storage are involved in Febrile Non Hemolytic Transfusion Reactions (FNHTRs) after Platelet transfusion, the aim of this study was the survey of these cytokines level in PCs produced in Tehran Blood Center. Materials and Methods: This study proposed to determine if WBC reduction in P...
The present investigation was carried out to assess the effect of Sephadex (G-15) filtration on the post thaw bull semen quality and conception rate. Post thaw unfiltered (control) and Sephadex filtered semen from four healthy bulls (three cross bred and one pure bred Holstein Friesian) were subjected to microscopic examination viz. sperm concentration, individual motility, live sperm count and...
BACKGROUND The relationship between impacted mandibular third molar and mandibular canal is important for removal of this tooth. Panoramic radiography is one of the commonly used diagnostic tools for evaluating the relationship of these two structures. OBJECTIVES To evaluate the accuracy of panoramic radiographic findings in predicting direct contact between mandibular canal and impacted thir...
introduction: the use of panoramic radiography has shown a remarkable expansion over the past 20 years. accurate positioning and preparation of patients is needed to avoid image distortion. the aim of this study was to evaluate the common errors on panoramic radiographs taken in the radiology department of rasht dental school. materials and methods: the study sample included 390 digital panoram...
INTRODUCTION This in vivo study assessed accuracy and reliability of tooth length measurements obtained from conventional panoramic radiographs and CBCT panoramic reconstructions to that of a digital caliper (gold standard). METHODS The sample consisted of subjects who had CBCT and conventional panoramic radiographic imaging and who required maxillary premolar extraction for routine orthodont...
Background and Aims: Overlapping of the proximal surfaces of posterior teeth in the panoramic radiography is a major concern. Therefore, an option has been developed in the panoramic unit of Planmeca Promax, namely improved interproximal mode. This mode causes lower horizental angle with the teeth contact region during the unit rotation decreasing overlapping of the panoramic images of the post...

background: one of the most frequent concerns encountered in dental implant treatments is inadequate pre‑operative planning. panoramic radiographs are readily accessible and cost efficient. the aim of this study is to assess the accuracy of vertical measurements in mandibular molar andpremolar region on panoramic radiography. materials and methods : panoramic radiographs were made of a partiall...
BV RI CCD-based and near-IR (J) imaging, together with unfiltered photometry of the hot subdwarf B star PG 0856+121 are reported. Two close, faint, red, point-like sources are resolved. They account for the previously reported IR excess observed in this hot subdwarf. In addition, the new unfiltered differential photometry of PG 0856+121 confirms its previously reported pulsational nature. A com...
