West Nile virus (WNV) non-structural protein 1 (NS1) elicits protective immune responses during infection of animals. WNV NS1-specific antibody responses can provide the basis for serological diagnostic reagents, so the antigenic sites in NS1 that are targeted by host immune responses need to be identified and the conservation of these sites among the(More)
PURPOSE The incidence of deep cervical space infections has decreased after the introduction of antibiotics and improvement of oral hygiene, but they still may be lethal especially when life-threatening complications occur. In this article, we try to find out whether there are predisposing factors related to complicated deep cervical space infections and(More)
This study involved seven patients with cerebral radionecrosis following radiation therapy for nasopharyngeal carcinoma (NPC). Their charts were reviewed and the relationship of extracranial malignancies to cerebral radionecrosis was investigated. The radiation dose ranged from 70 to 135 Gy, and the latency was from 6 to 39 months. Two of seven patients(More)
We present a case of polypoid sinusitis with maxillary sinus antrolith, which is composed of Aspergillus species. Unlike most muddy or necrotic fungal balls, this first reported fungal antrolith is solid and extremely hard. Aspergillus served as a central fungal nidus associated with long-standing sinusitis, and poor sinus drainage could be a possible(More)
A rhinolith is a stone that forms in the nose. It occurs as a result of the solidification of mucus and nasal debris by mineral salts, calcium, magnesium phosphate and carbonate. It can be seen on radiographs as a radiopaque object in the nasal fossa and may be confused with several pathologic entities that will call for more invasive surgical procedures.(More)
Matrix metalloproteinase (MMP) is involved in the upper airway remodeling process. We hypothesized that genetic variants of the MMP-9 gene are associated with cases of chronic rhinosinusitis with nasal polyposis. We conducted a case-control study where 203 cases of chronic rhinosinusitis with nasal polyposis and 730 controls were enrolled. Three tagging(More)
OBJECTIVE To study the farmer-workers'stress, their mental health and the effect of stress on mental health. METHODS The Stressors Scale and SCL-90 were used for the test in a sample of 500 farmer-workers. RESULTS The primary mental stressors of the farmer-workers were economic burden, protection of their rights and interests and working condition &(More)
Matrix metalloproteinase (MMP) is involved in the upper airway remodeling process. We hypothesized that MMP had an additive effect on the formation of recurrent nasal polyp. We also investigated the association between the functional promoter polymorphism of MMPs and the intensity of labeling index. Expressions of MMP-2 and MMP-9 were assessed via(More)
PURPOSE The etiology and mechanism of nasal polyps are still not well known. A newly discovered transcriptional factor, hypoxia-inducible factor (HIF), is a DNA-binding protein. Hypoxia-inducible factor is demonstrated to associate with various neoplasms. We investigate the expression of HIF-1alpha protein in nasal polyps compared with inferior turbinate(More)
BACKGROUND Matrix metalloproteinase (MMP) is involved in the remodeling process of inflammatory airway diseases and is correlated with the severity of asthma. We hypothesized that MMP was associated with the severity of chronic rhinosinusitis with nasal polyps (CRSwNPs). We also investigated the effect of allergy on the expression of MMP in the polyp.
