purpose: to report two cases of granulomatosis with polyangiitis (gpa) presented ocular manifestations. cases report: we report two cases of scleritis with red eye, one of them was a 30 years old female patient with saddle nose and positive c-anca and the other one was a 56 year-old female patient with lung cavitation and positive c-anca. both cases undergone corticosteroid and immunosuppressiv...

background staphylococcus aureus is a significant pathogen that can colonize the nares of different animals, causing a wide range of infections in various hosts. objectives we intended to determine the prevalence of s. aureus in the nasal cavity of healthy ruminants and also to investigate the presence of antibiotic resistance genes. materials and methods in the present study, healthy cattle (n...

In this paper we introduce the cone bounded linear mapping and demonstrate a proof to show that the cone norm is continuous. Among other things, we prove the open mapping theorem and the closed graph theorem in TVS-cone normed spaces. We also show that under some restrictions on the cone, two cone norms are equivalent if and only if the topologies induced by them are the same. In the sequel, we...

leprosy is an infectious and non-fatal disease that mainly involved skin and peripheral nervous system and caused by mycobacterium lepra. this case is a 41-year-old woman with intermittent nasal bleeding and a mass (1.5×2.5 cm) in the right side of lateral nasal wall and a (1×1 cm) mass on septum in the left side of the nose. considering the probability of intranasal tumor, endoscopic biopsy fo...

This study aimed to assess the effects of bone-borne and tooth-borne surgically assisted rapid maxillary expansion on the volumes of the nose and nasal airway 2 yr after maxillary expansion. This prospective cohort study included 32 patients with transverse maxillary hypoplasia. Expansion was performed with a tooth-borne distractor (Hyrax) in 19 patients and with a bone-borne distractor [transp...

PURPOSE Hyperbaric oxygen therapy has shown efficacies in the treatment of a number of diseases. The goal of this study was to develop a rodent hyperbaric chamber for MRI studies and to investigate the effects of hyperbaric air and hyperbaric oxygen on local magnetic field (B0 ) and MRI relaxation parameters in the rat brain. METHODS A hyperbaric chamber, constructed to fit inside an animal M...

SUMMARY Through analysis of earlier research and some recent on-road testing it is demonstrated that, with adequate precaution, accurate measurement of tire/pavement noise using on-board sound intensity (SI) can be accomplished with two intensity probes oriented vertically. As in the single probe method, SI is measured in the airflow alongside of a vehicle at locations opposite the leading and ...
