Abstract
The large variation of influenza A viruses (IAVs) in various susceptible hosts and their rapid evolution, which allows host/tissue switching, host immune escape, vaccine escape, and drug resistance, are difficult challenges for influenza control in all countries worldwide. Access and binding of the IAV to actual receptors at endocytic sites is critical for the establishment of influenza infection. In this chapter, the progress in identification of and roles of glycans and non-glycans on the epithelium and in the immune system in H1-H18 IAV infections are reviewed. The first part of the review is on current knowledge of H1-H16 IAV receptors on the epithelium including sialyl glycans, other negatively charged glycans, and annexins. The second part of the review focuses on H1-H16 IAV receptors in the immune system including acidic surfactant phospholipids, Sia on surfactant proteins, the carbohydrate recognition domain (CRD) of surfactant proteins, Sia on mucins, Sia and C-type lectins on macrophages and dendritic cells, and Sia on NK cells. The third part of the review is about a possible H17-H18 IAV receptor. Binding of these receptors to IAVs may result in inhibition or enhancement of IAV infection depending on their location, host cell type, and IAV strain. Among these receptors, host sialyl glycans are key determinants of viral hemagglutinin (HA) lectins for H1-H16 infections. HA must acquire mutations to bind to sialyl glycans that are dominant on a new target tissue when switching to a new host for efficient transmission and to bind to long sialyl glycans found in the case of seasonal HAs with multiple glycosylation sites as a consequence of immune evasion. Although sialyl receptors/C-type lectins on immune cells are decoy receptors/pathogen recognition receptors for capturing viral HA lectin/glycans protecting HA antigenic sites, some IAV strains do not escape, such as by release with neuraminidase, but hijack these molecules to gain entry and replication in immune cells. An understanding of the virus-host battle tactics at the receptor level might lead to the establishment of novel strategies for effective control of influenza.

Abstract
Chlorine is a toxic chemical that has been used as a chemical warfare agent in recent armed conflicts. There is an urgent need for methods to verify alleged uses of chlorine, and phospholipid chlorohydrins (PL-HOCl) derived from the pulmonary surfactant of exposed victims have previously been proposed as biomarkers of chlorine exposure. Here we describe an improved protocol for the chemical analysis of these biomarkers and its applicability to biomedical samples from chlorine-exposed animals. By the use of a polymeric solid phase-supported transesterification of PL-HOCl using ethanolamine, a common biomarker; oleoyl ethanolamide chlorohydrin (OEA-HOCl), was derived from all the diverse oleoyl PL-HOCl that may be formed by chlorine exposure. Compared to native lipid biomarkers, OEA-HOCl represents a larger biomarker pool and is better suited for nano-liquid chromatography tandem mass spectrometry (nLC-MS/MS analysis), generating 3 amol LOD and a reduced sample carry-over. With the improved protocol, significantly elevated levels of OEA-HOCl was identified in broncho-alveolar lavage fluid (BALF) of chlorine exposed rats, 2-48 hours after exposure. The difficulty of BALF sampling from humans limits the methods usefulness as a verification tool of chlorine exposure. Conversely, nasal lavage fluid (NLF) is readily collected without advanced equipment. In NLF from chlorine-exposed rats, PL-HOCl were identified and significantly elevated levels of the OEA-HOCl biomarker was detected 2- 24 hours after exposure. In order to test the potential of NLF as a biomedical sample for verification of human exposure to chlorine, in-vitro chlorination of human NLF samples was performed. All human in-vitro chlorinated NLF samples exhibited elevated OEA-HOCl biomarker levels, following sample derivatization. This data indicates the potential of human NLF as a biomedical sample for the verification of chlorine exposure but further work is required to develop and validate the method for the use on real-world samples.

Abstract
Since the discovery of surfactant, a large amount of knowledge has been accumulated about its biology and pharmacology. Surfactant is the cornerstone of neonatal respiratory critical care, but its proteins and phospholipids are produced in various tissues and organs, with possible roles only partially similar to that played in the alveoli. As surfactant research is focused mainly on its respiratory applications, knowledge about the possible role of surfactant in extrapulmonary disorders has never been summarized. Here we aim to comprehensively review the data about surfactant biology and pharmacology in organs other than the lung, especially focusing in the more promising surfactant extrapulmonary roles. We also review any preclinical or clinical data available about the therapeutic use of surfactant in these contexts. We offer a summary of knowledge and research/development milestones, as possible useful guidance for researchers of multidisciplinary background.

Abstract
Beside alveoli, surface active material plays an important role in the airway physiology. In the upper airways it primarily serves in local defense. Lower airway surfactant stabilizes peripheral airways, provides the transport and defense, has barrier and anti-edematous functions, and possesses direct relaxant effect on the smooth muscle. We tested in vitro the effect of two surfactant preparations Curosurf® and Alveofact® on the precontracted smooth muscle of intra- and extra-pulmonary airways. Relaxation was more pronounced for lung tissue strip containing bronchial smooth muscle as the primary site of surfactant effect. The study does not confirm the participation of ATP-dependent potassium channels and cAMP-regulated epithelial chloride channels known as CFTR chloride channels, or nitric oxide involvement in contractile response of smooth muscle to surfactant.By controlling wall thickness and airway diameter, pulmonary surfactant is an important component of airway physiology. Thus, surfactant dysfunction may be included in pathophysiology of asthma, COPD, or other diseases with bronchial obstruction.

Abstract
INTRODUCTION Surfactant protein (SP)-B is a hydrophobic protein secreted within pulmonary surfactant that facilitates the adsorption of surface-active lipids to the air-liquid interface of the alveoli and increases alveolar stability. SP-B may also have anti-inflammatory properties. It is implicated in decreasing the pulmonary inflammatory response to bacterial lipopolysaccharide. However, the expression and function of SP-B in the sinonasal cavities has not been elucidated. Our objective was to detect the presence of SP-B, measure alterations in several forms of chronic rhinosinusitis (CRS), and localize cellular protein expression. MATERIALS/METHODS Sinus mucosal biopsies were performed in patients with allergic fungal rhinosinusitis (AFRS), nonatopic CRS with nasal polyposis (NP), and cystic fibrosis (CF) and in healthy controls. SP-B mRNA was measured in CRS and control patients using quantitative polymerase chain reaction. Immunoblot analysis and immunolocalization of SP-B were also performed. RESULTS CF (n = 4) showed significantly increased levels of SP-B (169-fold) mRNA (P = .004) when compared with controls (n = 5). CRS with NP (n = 5) and AFRS (n = 7) also demonstrated elevated levels of SP- B (14-fold and 4-fold, respectively) when compared with the control group, although these were not statistically significant. Immunoblot analysis confirmed the presence of the translated product, and immunolocalization revealed expression in the epithelium and submucosal glandular elements. CONCLUSION This is the first study to detect and characterize SP-B in human sinus mucosa. Furthermore, SP-B is significantly up-regulated in CF CRS.

Abstract
BACKGROUND This study examined the light and the electron microscopic changes in the mucosa of primary atrophic rhinitis and compared them with the normal nasal mucosa to establish the changes in the surfactant system. A prospective original study was performed. METHODS Twenty cases of primary atrophic rhinitis were randomly selected in the outpatient clinic of Sohag University Ear, Nose, and Throat Department. Ten volunteers with no history of chronic nasal disease and with normal rhinopharyngeal picture were selected as control cases. A small punch biopsy was performed with a small forceps under local anesthesia from the medial edge of the inferior turbinate. After histological laboratory preparations, semithin sections (0.5-1 microm) were prepared by using an LKB ultramicrotome. The sections were stained by toluidine blue, examined by light microscope, and photographed. Ultrathin sections (500-800) from selected areas of the trimmed blocks were made and collected on copper grids. The ultrathin sections were then contrasted in uranyl acetate for 10 minutes and examined by electron microscope Jeol JEM-1010. RESULTS Light microscopy of primary atrophic epithelium revealed typical nonkeratinized stratified squamous epithelium to keratinized squamous epithelium with a thin layer of keratin on the surface. Well-developed desmosomes appeared between the epithelial cells. In the lamina propria, no submucosal glands could be seen. Electron microscopy of it revealed that the stratification of the epithelium increased. Sloughing of the superficial cells was observed in some regions of the proliferating epithelium. Epithelial penetration with neutrophils (mainly) and lymphocytes (some) could be seen. No numerous multilamellar bodies (MLBs) could be detected in these cases. An increased amount of collagenous fibers was observed in the basement membrane. CONCLUSION In primary atrophic rhinitis, the epithelial cells revealed that desmosomes are characteristic of the metaplastic squamous epithelium and had no MLB in their cytoplasm, and cells in which occasional MLBs had been established showed interdigitations between them and the surrounding cells, suggesting an association between the surfactant deficiency and the development of desmosomes.

Abstract
BACKGROUND Pulmonary surfactant originates from phospholipid lamellar bodies secreted from the type II epithelial cell of the alveolus. In the lower airway, surfactant optimizes surface tension and oxygen exchange, decreases mucus viscosity and aids in mechanical elimination of inhaled pathogens. In addition to the lung, lamellar bodies have been identified in many other cell types throughout the human body. However, no prior studies have identified lamellar bodies in human sinus mucosa. OBJECTIVES We performed ultrastructural studies to assess whether lamellar bodies are present in the human sinus in a variety of diseased and normal epithelium. METHODS We biopsied sinus mucosa from 5 subjects, 1 each with allergic fungal sinusitis, eosinophilic mucin rhinosinusitis, cystic fibrosis, frontal sinus mucocele, and cerebrospinal fluid leak (healthy control). Mouse lung served as a positive control. Specimens were prepared using ferrocyanide-reduced osmium tetroxide and thiocarbohydrazide for fixation (R-OTO method) to avoid extraction of phospholipids during dehydration and were viewed with transmission electron microscopy. RESULTS We identified lamellar bodies in the sinus mucosa of all patients. Additionally, preservation of mouse lung lamellar bodies confirms that the R-OTO method is a valid technique to preserve these structures. CONCLUSIONS We describe a simpler, faster technique for identification of cellular phospholipid components than those used previously. Definitive identification of these lamellar bodies within ciliated pseudostratified epithelium of the upper airway indicates that surfactant may have a role in sinus function and pathophysiology.

Abstract
Samples of the respiratory mucosa of children with recurrent respiratory infections suspected of having primary ciliary dyskinesia are routinely fixed with glutaraldehyde before ultrastructural examination. This standard technique, however, may not be optimal for visualizing ciliary components or for preserving several cellular and extracellular structures during dehydration and embedding procedures. In this study, brushes of nasal (28 samples) and/or tracheal (9 samples) mucosa from 32 children with recurrent respiratory tract infections were examined. Twenty-nine samples were fixed with glutaraldehyde supplemented with tannic acid to determine if the ultrastructural analysis of respiratory epithelium and bronchial secretions could be improved. Eight samples were conventionally fixed with glutaraldehyde alone. Lesions of the cellular membrane and damaged cells were easily visualized using tannic acid supplemented fixation. Internal ciliary structures including individual microtubules and dynein arms were also more clearly observed. In addition, the internal structure of microvilli of the respiratory epithelium could be studied and the presence of phospholipid-rich surfactant-like material within nasal and tracheal secretions were visualized after tannic acid supplemented fixation. We suggest that addition of tannic acid during fixation is useful for accurate ultrastructural evaluation of respiratory mucosa in both clinical and experimental situations.

Abstract
In the optic tectum of goldfish, the outer, middle and inner layers of the endomeninx were evident in animals ranging in age from 1 month to several years. The outer layer in young animals consisted of closely overlapping cells with intertwined processes, whereas in the older animals it contained large extracellular spaces. The intermediate layer cells were always arranged in a single continuous layer, but in young animals they overlapped extensively with one another toward their edges whereas in the oldest animals they became extremely flat and non-overlapping. The inner layer included an outer tier of cells with their bases adhering to the intermediate layer, and an inner tier of cells detached from both the intermediate layer and the basal lamina overlying the brain parenchyma. Inner layer cells contained many large vacuoles that were in continuity with the extracellular space. With age, the extracellular space and the vacuolar system expanded, and the inner layer evolved into a meshwork of attenuated cytoplasmic processes embedded in the granular extracellular matrix. Another age-related feature was the accumulation adjacent to the basal lamina of uniform disc-shaped membranous structures, resembling multilamellar bodies of lung surfactant. These "disc bodies" were apparently generated by the coalescence of vesicles formed at the surface of the inner layer cells, possibly as a by-product of protein secretion by these cells.
