| It has been postulated that the nasal mucosa, like other human tissues, is affected by a complex interactive network of neuropeptides, cytokines, allergic and inflammatory mediators and hormones such as estrogen, in which associations between symptoms (e.g. nasal stuffiness and coryza) and hormonal variations deriving from pregnancy, use of hormonal contraceptives and menstrual cycle phases are observed. The objective is evaluating the presence of specific estrogen receptors (types alpha and beta) in inferior turbinate mucosa in healthy subjects without nasal symptoms. Samples of nasal inferior turbinate were removed from patients undergoing aesthetic nasal surgery, and analyzed using hematoxylin-eosin staining, followed by immunohistochemical preparations... |

| There is no consensus about the precise definition of what the cardia is. Although this term is often utilized in the medical literature, it takes on a variety of meanings, depending on the context. For histologists and endoscopists, the cardia is a region of the stomach immediately below the gastroesophageal junction. However, the concepts of gastroesophageal junction used by histologists and endoscopists are not the same as used by anatomists. This junction is histologically defined as the abrupt transition from the nonkeratinized stratified squamous epithelium of the esophagus to simple columnar epithelium and corresponds to the endoscopically defined Z-line. Nevertheless, this epithelial change does not occur exactly in the anatomical transition... |
