Abstract
Besides maintaining a physical barrier with adherens junctional (AJ) and tight junctional proteins, airway epithelial cells have important roles in modulating the inflammatory processes of allergic asthma. E-cadherin and β-catenin are the key AJ proteins that are involved in airway remodeling. Various mediators such as transforming growth factor-β (TGF-β), epidermal growth factor (EGF), fibroblast growth factor (FGF), platelet derived growth factor (PDGF), insulin-like growth factor (IGF), tumor necrosis factor-α (TNF-α) and angiogenic factors, such as vascular endothelial growth factor (VEGF), are released by the airway epithelium in allergic asthma. The signaling pathways activated by these growth factors trigger epithelial-mesenchymal transition (EMT), which contributes to fibrosis and subsequent downregulation of E-cadherin. The present study used a mouse asthma model to investigate the effects of anti-VEGF, anti-TNF and corticosteroid therapies on growth factor and E-cadherin/β-catenin expression. The study used 38 male BALB/c mice, divided into 5 groups. A chronic mouse asthma model was created by treating 4 of the groups with inhaled and intraperitoneal ovalbumin (n= 8 per group). Saline, anti-TNF-α (etanercept), anti-VEGF (bevacizumab) or a corticosteroid (dexamethasone) were applied to each group by intraperitoneal injection. No medication was administered to the control group (n=6). Immunohistochemistry for E-cadherin, β-catenin and growth factors was performed on lung tissues and protein expression levels assessed using H-scores. Statistically significant differences were observed in E-cadherin, β-catenin, EGF, FG, and PFGF (P<0.001 for all) as well as the IGF H-scores between the five groups (P<0.005). Only anti-VEGF treatment caused E-cadherin and β-catenin levels to increase to the level of non-asthmatic control groups (P>0.005). All treatment groups had reduced TGF-β, PDGF and FGF H-scores in comparison with the untreated asthma group (P=0.001). The EGF and IGF levels were not significantly different between the untreated asthmatic and non-asthmatic controls. The results suggested that anti-VEGF and TNF-α inhibition treatments are effective in decreasing growth factors, in a similar manner to conventional corticosteroid treatments. Anti-VEGF and TNF inhibition therapy may be an effective treatment for remodeling in asthma while offering an alternative therapeutic option to steroid protective agents. The data suggested that anti-VEGF treatment offered greater restoration of the epithelial barrier than both anti-TNF-α and corticosteroid treatment.

Abstract
Background:While the pathophysiology of chronic disorders varies there are three basic mechanisms - inflammation, oxidative stress and endothelial dysfunction – that are common in many chronic diseases. These mechanisms, which have a dynamic structure, are key to homeostasis. However, the failure of these mechanisms to work synchronously can lead to morbidity complicating the course of many chronic diseases.Objectives:To evaluate the effect of anti-atherosclerotic liquid (AAL), anti-inflammatory capsules (AIC) and anti-oxidant liquid (AOL) supplementation on the flow-mediated dilatation (FMD), inflammatory, oxidative stress and endothelial dysfunction markers in patients with selected chronic diseasesMethods:We analyzed data of 178 patients from cohorts with selected chronic diseases (Rheumatoid arthritis, familial Mediterranean fever, DM type-2, Hypertension, Multiple sclerosis, Chronic obstructive pulmonary disease, Alzheimer disease and Cancer) in this quasi-experimental study. Endothelial dysfunction was determined by FMD and serum asymmetric dimethylarginine (ADMA) levels. Serum ADMA, high sensitive C-reactive protein (hs-CRP), serum PTX3, malondialdehyde (MDA), Cu/Zn-superoxide dismutase (Cu/Zn-SOD), glutathione peroxidase (GSH-Px) levels and FMD were studied in baseline and after 12 weeks of Morinda citrifolia (AAL, 3 ml once per day), omega-3 (AIC, 3 capsules once per day) and extract with Alaskan blueberry and 21 different red purple fruit vegetables (AOL, 30 ml once per day). Stepwise multivariate regression analysis evaluated the association of FMD with clinical and serologic parameters.Results:Serum ADMA, MDA, PTX3, hsCRP and albumin levels, and proteinuria were significantly decreased and CuZn-SOD, GSH-Px and FMD levels were significantly increased following AAL, AIC and AOL therapies. FMD was negatively correlated with serum ADMA, MDA, PTX3, hsCRP levels, SBP and DBP and positively correlated to CuZn-SOD and eGFR levels both at baseline and after the 12-weeks treatment period. Multivariate regression analysis revealed that ADMA and PTX3 levels were independently related to FMD both before and after AAL, AIC and AOL therapies (Table 1, Figure 1).Conclusion:Our study shows that serum ADMA, MDA, PTX3 levels are associated with endothelial dysfunction in patients with selected chronic diseases. Short-term AAL, AIC and AOL therapies significantly improves FMD and normalizes ADMA, PTX3, hsCRP and MDA. This may have implications for adjunctive therapy in a number of chronic disorders.References:[1] Yilmaz MI, Saglam M, Caglar K, Cakir E, Sonmez A, Ozgurtas T et al.

Abstract
The number of older patients admitted to emergency departments (ED) increases continuously. The Identification of Seniors at Risk (ISAR) score is currently recommended to screen patients in German ED, but its appropriateness is being criticized. ISAR scores and clinical characteristics from 98 emergency admissions (EA), 80 from acute geriatrics (AG) and 89 from a geriatric rehabilitation (GR) unit were compared retrospectively. No significant differences were found between groups, being the ISAR score positive in 87.7% of EA, 94.9% of AG and 94.4% of GR cases. None of positively identified geriatric patients in the EA was transferred to the geriatric ward of competence. EA patients showed significantly higher number of functional impairments (p = 0.001) and higher BI score (p < 0.0001) compared to AG and GR groups. A higher ISAR score threshold and additional functional information might be needed to better select patients in need of prompt treatment by a geriatric team.

Abstract
BACKGROUND AND PURPOSE The limitations inherent in the current methods of diagnosing mild cognitive impairment have constrained the use of early therapeutic interventions to delay the progression of mild cognitive impairment to dementia. This study evaluated whether quantifying enlarged perivascular spaces observed on MR imaging can help differentiate those with mild cognitive impairment from cognitively healthy controls and, thus, have an application in the diagnosis of mild cognitive impairment. MATERIALS AND METHODS We automated the identification of enlarged perivascular spaces in brain MR Images using a custom quantitative program designed with Matlab. We then quantified the densities of enlarged perivascular spaces for patients with mild cognitive impairment (n = 14) and age-matched cognitively healthy controls (n = 15) and compared them to determine whether the density of enlarged perivascular spaces can serve as an imaging surrogate for mild cognitive impairment diagnosis. RESULTS Quantified as a percentage of volume fraction (v/v%), densities of enlarged perivascular spaces were calculated to be 2.82 ± 0.40 v/v% for controls and 4.17 ± 0.57 v/v% for the mild cognitive impairment group in the subcortical brain (P < .001), and 2.74 ± 0.57 v/v% for the controls and 3.90 ± 0.62 v/v% for the mild cognitive impairment cohort in the basal ganglia (P < .001). Maximum intensity projections exhibited a visually conspicuous difference in the distributions of enlarged perivascular spaces for a patient with mild cognitive impairment and a control patient. By means of receiver operating characteristic curve analysis, we determined the sensitivity and specificity of using enlarged perivascular spaces as a differentiating biomarker between mild cognitive impairment and controls to be 92.86% and 93.33%, respectively. CONCLUSIONS The density of enlarged perivascular spaces was found to be significantly higher in those with mild cognitive impairment compared with age-matched healthy control subjects. The density of enlarged perivascular spaces, therefore, may be a useful imaging biomarker for the diagnosis of mild cognitive impairment.

Abstract
BACKGROUND Sinomenine (SIN), an alkaloid isolated from the root of Sinomenium acutum which has a variety of pharmacological effects, including anti-inflammation, immunosuppression and anti-angiogenesis. The present study aimed to evaluate the effects of SIN on airway remodelling, epithelial apoptosis, and T Helper (Th)-2 derived cytokine levels in a murine model of chronic asthma. METHODS Twenty-two BALB/c mice were divided into four groups; I (control), II (placebo), III, IV. Mice in groups III and IV received the SIN (100mg/kg), and dexamethasone (1mg/kg) respectively. Epithelium thickness, sub-epithelial smooth muscle thickness, number of mast and goblet cells of samples isolated from the lung were measured. Immunohistochemical scorings of the lung tissue for matrix metalloproteinase-9 (MMP-9), vascular endothelial growth factor (VEG-F), transforming growth factor-beta (TGF-β), terminal deoxynucleotidyl transferase-mediated dUTP nick endlabeling (TUNEL) and cysteine-dependent aspartate-specific proteases (caspase)-3 were determined. IL-4, IL-5, IL-13, Nitric oxide in bronchoalveolar lavage fluid (BALF) and ovalbumin-specific immunoglobulin (Ig) E in serum were quantified by standard ELISA protocols. RESULTS The dose of 100mg/kg SIN treatment provided beneficial effects on all of the histopathological findings of airway remodelling compared to placebo (p<0.05). All cytokine levels in BALF and serum and immunohistochemical scores were significantly lower in 100mg/kg SIN treated group compared to the placebo (p<0.05). CONCLUSIONS These findings suggested that the dose of 100mg/kg SIN improved all histopathological changes of airway remodelling and its beneficial effects might be related to modulating Th-2 derived cytokines and the inhibition of apoptosis of airway epithelial cells.

Abstract
Objective The aim of this study was to investigate the accuracy of bedside lung ultrasound (BUS) in the diagnosis of community-acquired pneumonia (CAP) in patients with dyspnoea presenting to the emergency department (ED) and to analyse the characteristic sonographic findings of CAP. Methods After a six-hour training program, BUS procedures were performed between October 2011 and February 2012 to prospectively evaluate patients presenting to the ED with dyspnoea. Chest X-ray (CXR) or computerised tomography (CT) were ordered, depending on the presence of consolidation signs on CXR. The outcome was determined by consolidation findings on CXR or CT. BUS results were compared using Chi-squared testing. Results Of the 112 enrolled patients with dyspnoea, 40 patients were excluded and 72 were included in the study. Thirty-four patients were BUS positive. Of these, CXR or CT findings agreed with the BUS findings in 27 patients. In 38 cases, BUS was negative, and one patient was diagnosed with pneumonia based on the CT report. The sensitivity, specificity, PPV, NPV, and the positive and negative likelihood ratios for BUS were 96.4%, 84.1%, 79.4%, 97.4%, 6.1 and 0.042, respectively. The diagnostic accuracy of BUS was 89%. The presence of consolidation signs, either shred or hepatisation, were the most frequent sonographic findings in our study. Conclusions Acute alveolar consolidation can be diagnosed easily by performing BUS with high degree of accuracy in EDs.

Abstract
Biofilm-related infections are chronic infections that cause serious increase in morbidity and mortality as well as significant economic loss. Galleria mellonella larva is shown as a reliable animal model for in vivo toxicology and pathogenicity tests due to its large size, ease of practice, ability to survive at 15-37°C and its similarity to mammals' natural immune system. The aim of this study was to evaluate the effects biofilm activity of Candida albicans in a G.mellonella larva model. Two C.albicans strains isolated as a disease agent were used for the model, where one was positive (BP), and the other one was negative (BN) for biofilm production. Eighty healthy G.mellonella larvae, all in the last larval stage and 2-2.5 cm long, were divided into 4 groups of equal size. Group 1 was set as the control group. Group 2 was injected with sterile phosphate buffer (PBS) group. Group 3 was injected with BP C.albicans strain and group 4 with BN C.albicans strain. A 5 μL volume of C.albicans prepared at 5 × 105 cfu/ml concentration with PBS was injected into the last left rear-legs of the larvae. The larvae were kept in sterile petri dishes at 37°C. They were observed for a total of 96 hours, for 4 hours in the first 24 hours, then in 12 hours intervals. Melanization, survival, total hemocyte count and fungal burden were evaluated as infection indicators. Melanization and death were not observed throughout the study period in group 1. One larva died in group 2. Small melanization spots (dark spots) and subsequent progressive melanization were observed from 3rd hour in the larvae infected with C.albicans. When compared with the BN C.albicans infected group, survival rate was 20% for BP C.albicans infected larvae at the end of 24 hours. Total hemocyte count was very low in the infected groups compared to groups 1 and 2, also significantly lower in group 3 than in group 4. In quantitative cultures, growth of C.albicans was detected in groups 3 and 4 while not in groups 1 and 2. Fungal load was significantly higher in BP C.albicans infected group than BN C.albicans infected group. In this study, G.mellonella larvae were used as live hosts to demonstrate the effects of biofilm activity of C.albicans. Our results suggest that larval models can be used to investigate the effects of fungal infections and biofilm like virulence factors on host cells, and invertebrate animal models can be widely used and can bridge between in vitro studies and mammalian models.

Abstract
Objective: Detection/localization of infection and inflammation is important for the initiation of correct treatment as well as its maintenance. Nuclear medicine imaging methods play an important role in determining infection and inflammation. 18F-2’-deoxy-2-fluoro-d-glucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) is highly sensitive in such cases when used with tomographic cross-sections. In this study, the development and progression of infection and inflammation were monitored on rats by using 18F-FDG via PET/CT. Methods: Sterile and infected abscesses were formed on rats using turpentine and S. aureus, respectively. For evaluation of the formation and progression of the abscess, 18F-FDG was injected into the rats and they were imaged by PET/CT at intervals of twenty-four hours for five days. Maximum standard uptake value (SUVmax) of 18F-FDG was calculated. Results: The highest activity involvement was seen on the first day of abscess formation. On the first day, SUVmax of the S. aureus abscess was 3.9±0.9 while in the sterile abscess SUVmax in the first day was 2.2±0.8. 18F-FDG uptake decreased day by day and it reached the background level on the fourth and fifth days. There were statistically significant differences between S. aureus and sterile abscess, and between sterile abscess and background activity in terms of SUVmax values during the first three days (p<0.05). On the fourth and fifth days, there was no statistically significant difference between S. aureus and sterile abscess, and between sterile abscess and background activity (p>0.05). Conclusion: The results demonstrated that the SUVmax value for 18F-FDG can be useful in the early differentiation of sterile and infected abscess. In addition, 18F-FDG-PET imaging has the advantage of local availability of equipment and labeled agents leading rapid diagnosis of differentiation of infection and inflammation.

Abstract
Bone marrow-derived mesenchymal stem cells (BMSCs) can ameliorate a variety of lung diseases such as asthma, lung fibrosis, and acute lung injury by its anti-inflammatory and immunmodulatory effects. In this study, we developed a mouse model of bronchiolitis obliterans (BO) and evaluated the effects of the intraperitoneal administration of BMSCs on lung histopathology and cytokine levels. 25 BALB/c mice were divided into four groups; control group (Group I), BO developed and 1x106 BMSCs-injected group (Group II), non-BO, 1x106 BMSCs-injected group (Group III), and BO developed and saline-injected group (Group IV). Histological and immunohistochemical findings of the lung tissue and the migration of BMSCs to the lung were evaluated using light and confocal microscopy techniques. Confocal microscopy evaluations showed that there was no noteworthy amount of BMSCs in the lung tissue of group III while significant amount of BMSCs was detected in group II. Wall thicknesses of terminal bronchiole and periterminal bronchiolar collagen deposition were significantly lower in group II compared to the group IV (p<0.05). Furthermore, according to the immunohistochemical staining results, CD3, CD4, CD8, CD20, CD68 and neutrophil elastase positive immune cells of group II were stained more positive than group IV cells (p<0.05). IFN-γ IL-2 and TNF-α levels in bronchoalveolar lavage fluid (BALF) were significantly lower in group II compared to group IV (p<0.05). The findings of this study indicate that intraperitoneally administered BMSCs have potent effects on histopatological changes of the lung tissue and cytokine levels in the murine model of BO.

Abstract
AIMS This study aimed to investigate the application of Origanum vulgare L. essential oil (EO) as an alternative antimicrobial agent against vaginal infections. METHODS AND RESULTS Microdilution methods were applied for the detection of the minimal inhibitory (MIC) and the minimal bactericidal/fungicidal (MBC/MFC) concentration of 15 clinical strains originating from women with symptoms of vaginal infection. Optical density determination (OD) was used for detection of the Candida growth rate. Staining with DAPI was used to detect the influence of EO on nuclear condensation and fragmentation, while the brine shrimp bioassay was used to determine the toxicity of EO. Chemical composition analysis was done using GS-MS. According to the MIC and MBC/MFC values, the most susceptible strains to EO were: Escherichia coli 1, E. coli 2, Staphylococcus aureus 3 and Candida albicans 1-3. Inhibition of C. albicans filamentation was detected at 0·45 μl ml-1 . CONCLUSIONS The obtained inhibition (%) from Candida growth curves points to a shorter period of time (24 h) for determining IC50 as MIC and IC99 as MFC value. These values could be recommended as valid parameters for the faster detection of the effectiveness of EO on Candida isolates. SIGNIFICANCE AND IMPACT OF THE STUDY Examination of potential of the O. vulgare EO as a main antimicrobial constituent within vaginalettes in gynaecological practice.

Abstract
Objective The aim of the study was to investigate the role of Hepatocyte Growth Factor (HGF)/c-Met pathway in testicular damage provoked by streptozotocin (STZ)- induced diabetes and the effects of insulin treatment on the HGF/c-Met pathway. Methods Total 21 paraffin-embedded testicular tissues of control (n=7), streptozotocin (STZ)-induced diabetic (n=7) and insulin-treated diabetic (n=7) Wistar albino rats were used in this study. Testicular damage was examined histologically and by Johnsen's score was also evaluated. Immunohistochemical stainings of HGF and c-Met were analysed by using antibodies against HGF and c-Met. Results We found the degeneration in seminiferous tubule epithelium and disorganization of spermatogenetic cell series in testis tissues of diabetic rats. We also determined decrease both in seminiferous tubule diameter and Johnsen's scores in diabetic group. The expressions of HGF and c-Met in seminiferous tubule epithelium and in spermatogenic cells (especially spermatocytes and spermatids) were significantly increased in diabetic rats compared to those of control. Insulin treatment significantly reduced the diabetes-induced morphological changes and HGF/c-Met over expressions in the diabetic rat testis. Conclusion HGF/c-Met pathway might have a role in diabetes- induced testicular damage. Drugs acting on this pathway might be effective to prevent or delay the testicular damage induced by diabetes.

Abstract
BACKGROUND Parthenolide is the active constituent of the plant 'Tanacetum parthenium' (Feverfew) which has been used for centuries as a folk remedy for inflammatory conditions. AIM OF THE STUDY In this study we aimed to investigate the effects of parthenolide in a murine model of chronic asthma. MATERIALS AND METHODS Thirty-five BALB/c mice were divided into five groups; I (control), II (placebo), III (dexamethasone), IV (parthenolide) and V (dexamethasone and parthenolide combination). Lung histology was evaluated after treatment with the study drugs. Levels of interleukin (IL)-4 and IL-5 were determined by ELISA. RESULTS Histologic parameters except the number of mast and goblet cells improved in the parthenolide group when compared with placebo. All parameters except basal membrane thickness and number of mast cells were improved significantly better in the group receiving dexamethasone when compared with the parthenolide group. Improvement of most of the histologic parameters was similar in Groups III and V. Interleukin-4 levels were significantly reduced in the parthenolide group when compared to the placebo group. CONCLUSION We demonstrated that parthenolide administration alleviated some of the pathological changes in asthma. But parthenolide alone is not efficient as dexamethasone therapy and the parthenolide and dexamethasone combination also did not add any beneficial effect to the dexamethasone treatment.

Abstract
Quercetin is a dietary flavonoid which has anti-inflammatory effects. This study aimed to evaluate the influence of quercetin on histopathological aspects and airway epithelium in allergic airway inflammation mice model. Twenty-eight BALB/c mice were randomly divided into four groups: Group I (control), Group II (untreated mice with allergic airway inflammation), Group III (allergic airway inflammation quercetin-treated [16mg/kg/day]), Group IV (allergic airway inflammation dexamethasone-treated [1mg/kg/day]). Ovalbumin was administered intraperitoneally and via inhalation to achieve allergic airway inflammation mice model and treatments were also given intraperitoneally. Epithelium thickness, subepithelial smooth muscle thickness, number of mast and goblet cells, and basement membrane thickness were examined on samples isolated from lung. Immunohistochemical evaluationof lung tissues was performed using IL-25, IL-33, thymic stromal lymphopoietin (TSLP), terminal deoxynucleotidyl transferase-mediated dUTP nick endlabeling (TUNEL) and cysteine-dependent aspartate-specific proteases(caspase)-3 antibodies. IL-4, IL-25, IL-33, TSLP were quantified in bronchoalveolar lavage (BAL) and OVAspecific IgE levels was measured in serum by standard ELISA protocols. IL-25, IL-33, thymic stromal lymphopoietin (TSLP) and cysteine-dependent aspartate-specific proteases (caspase)-3. Quercetin treatment led to lower epithelial thickness, subepithelial smooth muscle thickness, goblet and mast cell numbers compared to untreated mice with allergic airway inflammation (p<0.05). However, quercetin treatment was not effective on improving basal membane thickness. Immunohistochemical scores of IL-25, IL-33, TSLP, caspase-3 and TUNEL were lower in quercetin-treated mice t compared to untreated mice with allergic airway inflammation (p<0.05). IL-4, IL-25, IL-33, TSLP levels in BAL and OVA-specific IgE in serum were lower in quercetin treated mice compared to untreated mice (p<0.05). These findings suggest that quercetin improves chronic histopathological changes except basal membrane thickness in lung tissue and its beneficial effects on inflammation might be related to modulating epithelium derived cytokines and epithelial apoptosis.

Abstract
Previous studies showed that bone marrow-derived mesenchymal stem cells (BMSCs) could ameliorate a variety of immune-mediated and inflammatory diseases due to their immunomodulatory and anti-inflammatory effects. In this study, we developed a mouse model of ovalbumin (OVA) induced allergic inflammation in the upper airways and evaluated the effects of the intraperitoneal administration of BMSCs on allergic inflammation. Twenty-five BALB/c mice were divided into five groups; group I (control group), group II (sensitized and challenged with OVA and treated with saline-placebo group), group III (sensitized and challenged with OVA and treated with 1 × 106 BMSCs), group IV (sensitized and challenged with OVA and treated with 2 × 106 BMSCs), and group V (sensitized and challenged with phosphate buffered saline (PBS) and treated with 1 × 106 BMSCs). Histopathological features (number of goblet cells, eosinophils and mast cells, basement membrane, epithelium thickness, and subepithelial smooth muscle thickness) of the upper and lower airways and BMSCs migration to nasal and lung tissue were evaluated using light and confocal microscopes. Levels of cytokines in the nasal lavage fluid and lung tissue supernatants were measured using enzyme-linked immunosorbent assay (ELISA). Confocal microscopic analysis showed that there was no significant amount of BMSCs in the nasal and lung tissues of group V. However, significant amount of BMSCs were observed in group III and IV. In OVA-induced AR groups (group II, III, and IV), histopathological findings of chronic asthma, such as elevated subepithelial smooth muscle thickness, epithelium thickness, and number of goblet and mast cells, were determined. Furthermore, the number of nasal goblet and eosinophil cells, histopathological findings of chronic asthma, and IL-4, IL-5, IL-13, and NO levels was significantly lower in both BMSCs-treated groups compared to the placebo group. Our findings indicated that histopathological findings of chronic asthma were also observed in mice upon AR induction. BMSCs migrated to the nasal and lung tissues following intraperitoneal delivery and ameliorated to the airway remodeling and airway inflammation both in the upper and lower airways via the inhibition of T helper (Th) 2 immune response in the murine model of AR.

Abstract
Aminoglycoside antibiotics and imipenem are reported to stimulate exopolysaccharide alginate production and cause an increased biofilm volume in Pseudomonas aeruginosa. Recently, some remarkable studies have been conducted on the effects of curcumin (Turmeric), which is the fenolic form of Curcuma longa plant, on virulence factors of P.aeruginosa. In this study, we aimed to investigate the effects of MIC and sub-MIC concentrations of imipenem, tobramycin, and curcumin on biofilm formation of P.aeruginosa strains. P.aeruginosa strains (n= 2) used in this study were isolated from deep oropharyngeal swab samples of two cystic fibrosis patients. Antimicrobial susceptibilities of the two strains to imipenem, tobramycin, and curcumin were investigated by broth microdilution method, and biofilm production was assessed by using crystal violet staining method. In our study, MIC values of imipenem, tobramycin and curcumin for strain-1 were 8 µg/ml, 8 µg/ml and 16 µg/ml, respectively, while those values were 4 µg/ml, 8 µg/ml and 16 µg/ml for strain-2. Biofilm optical density values of the strain-1 and strain-2 before being treated with the test substances were 0.937 and 0.313 (control: 0.090), respectively, Biofilm optical densities of the both strains showed an increase following treatment with MIC concentrations of imipenem and tobramycin. The treatment of the strains with MIC and sub-MIC concentrations of curcumin led to no significant increase in biofilm optical density. The data obtained in this study supported the promising inhibitory effect of curcumin on P.aeruginosa biofilms. However, further more comprehensive studies are required to provide satisfactory data about the use of curcumin to treat P.aeruginosa infections characterized by biofilm formation.

Abstract
Background. Resveratrol is a natural polyphenol that exhibits anti-inflammatory effects. The aim of this study was to investigate the effects of resveratrol treatment on epithelium-derived cytokines and epithelial apoptosis in a murine model of atopic dermatitis-like lesions. Material and Methods. Atopic dermatitis-like lesions were induced in BALB/c mice by repeated application of 2,4-dinitrofluorobenzene to shaved dorsal skin. Twenty-one BALB/c mice were divided into three groups: group I (control), group II (vehicle control), and group III (resveratrol). Systemic resveratrol (30 mg/kg/day) was administered repeatedly during the 6th week of the experiment. After the mice had been sacrificed, skin tissues were examined histologically for epithelial thickness. Epithelial apoptosis (caspase-3) and epithelium-derived cytokines [interleukin (IL)-25, IL-33, and thymic stromal lymphopoietin (TSLP)] were evaluated immunohistochemically. Results. Epithelial thickness and the numbers of IL-25, IL-33, TSLP and caspase-3-positive cells were significantly higher in group II compared to group I mice. There was significant improvement in epithelial thickness in group III compared with group II mice (p < 0.05). The numbers of IL-25, IL-33, and TSLP-positive cells in the epithelium were lower in group III than in group II mice (p < 0.05). The number of caspase-3-positive cells, as an indicator of apoptosis, in the epithelium was significantly lower in group III than in group II mice (p < 0.05). Conclusion. Treatment with resveratrol was effective at ameliorating histological changes and inflammation by acting on epithelium-derived cytokines and epithelial apoptosis.

Abstract
BACKGROUND Demographic changes have resulted in an increase in the number of older (> 75 years) multimorbid patients in clinics. In addition to the primary acute diagnoses that lead to hospitalization, this group of patients often has cognitive dysfunctions, such as delirium. According to clinical experience, delirium patients are more time-consuming for clinicians and their function is often poor. The costs caused by delirium patients are currently unknown. In the present study, a retrospective examination of a database was carried out to calculate the costs that arise during the clinical treatment of documented delirium patients. SETTING AND METHODS The purpose of this retrospective analysis was to collect information recorded by nursing personnel trained in the treatment of delirium and information from a manual documentation matrix for additional time expenditure. In the database analysis anonymous data of previously discharged patients for a time window of 3 months were analyzed. Documented additional expenditure for patients with hyperactive delirium at hospitalization were analyzed by personnel. Material costs, the duration of hospitalization by main diagnosis and age clusters during hospitalization until discharge were also examined. The analysis was performed in a hospital with internal wards. RESULTS Data for 82 hyperactive delirium patients were examined and an average of approximately 240 min of additional personnel expenditure for these patients was found. These patients were approximately 10 years older (p < 0.01) and were hospitalized for an average of 4.2 days longer (p < 0.01) than non-delirium patients. Hyperactive delirium usually developed within the first 5 days of hospitalization and lasted 1.6 days on average. Patients for whom hyperactive delirium was detected early were hospitalized for significantly less time than those for whom it was detected late (6.85 versus 13.61 days, p = 0.002). Additionally, calculated personnel and material costs, including costs affecting the hospitalization period, amounted to approximately 1200 € per hyperactive delirium patient. This corresponds to approximately 0.3 CMP (casemix points) per patient. CONCLUSION The calculations of personnel and material costs and duration of hospitalization in patients with hyperactive delirium demonstrated significant additional costs. Early routine detection of delirium can be achieved through training and this approach leads to a shortening of the hospitalization period and lower costs.

Abstract
AIM: To investigate the effects of nilotinib in a rat model of indomethacin-induced enterocolitis.
METHODS: Twenty-one Wistar albino female rats obtained from Dokuz Eylul University Department of Laboratory Animal Science were divided into the following three groups: control (n = 7), indomethacin (n = 7) and nilotinib (n = 7). A volume of 0.25 mL of physiological serum placebo was administered to the control and indomethacin groups through an orogastric tube for 13 d. To induce enterocolitis, the indomethacin and nilotinib groups received 7.5 mL/kg indomethacin dissolved in 5% sodium bicarbonate and administered subcutaneously in a volume of 0.5 mL twice daily for three days. Nilotinib was administered 20 mg/kg/d in two divided doses to the nilotinib group of rats for 13 d through an orogastric tube, beginning on the same day as indomethacin administration. For 13 d, the rats were fed a standard diet, and their weights were monitored daily. After the rats were sacrificed, the intestinal and colonic tissue samples were examined. The macroscopic and microscopic pathology scores were evaluated. The pathologist stained all tissue samples using terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labeling method. Mucosal crypts and apoptotic cells were quantified. The platelet-derived growth factor receptor (PDGFR) α and β scores assessed by immunohistochemical staining method and tissue and serum tumor necrosis factor (TNF) α levels were determined by enzyme-linked immunosorbent assay.
RESULTS: Between days 1 and 13, the rats in the nilotinib and indomethacin groups lost significantly more weight than the controls (-11 g vs +14.14 g, P = 0.013; -30 g vs +14.14 g, P = 0.003). In the small intestinal and colonic tissues, the macroscopic scores were significantly lower in the nilotinib group than in the indomethacin group (1.14 ± 0.38 and 7.29 ± 2.98, P = 0.005; 1.14 ± 0.38 and 7.43 ± 2.64, P = 0.001, respectively), but the values of the nilotinib and indomethacin groups were similar to the control group. In the small intestinal and colonic tissues, the microscopic scores were significantly lower in the nilotinib group than in the indomethacin group (3.43 ± 2.99 and 7.67 ± 3.67, P = 0.043; 2.29 ± 0.76 and 8.80 ± 2.68, P = 0.003, respectively), but the values were similar to the control group. The PDGFR β scores in the small intestine and colon were significantly lower in the nilotinib group than in the indomethacin group (1.43 ± 0.79 and 2.43 ± 0.54, P = 0.021; 1.57 ± 0.54 and 3 ± 0, P =0.001), and the values were similar to controls. The colonic PDGFR α scores were significantly lower in the nilotinib group than in the indomethacin group (1.71 ± 0.49 and 3 ± 0, P = 0.001). The colonic apoptosis scores were significantly lower in the controls than in the nilotinib group (1.57 ± 1.13 and 4 ± 1.29, P = 0.007). Furthermore, the serum and tissue TNF-α levels were similar between the nilotinib and indomethacin groups.
CONCLUSION: In the indomethacin-induced enterocolitis rat model, nilotinib has a positive effect on the macroscopic and microscopic pathologic scores, ensuring considerable mucosal healing. Nilotinib decreases PDGFR α and β levels and increases the colonic apoptotic scores, but it has no significant effects on weight loss and the TNF-α levels.

Abstract
AIMS The aims of study were to examine the antibacterial potential of two commercial essential oils (EOs) from coriander (Coriandrum sativum L.) and thyme (Thymus vulgaris L.) against vaginal clinical strains of bacteria and yeast and their chemical composition. METHODS AND RESULTS Antimicrobial activities of commercial essential oils were determined using macro-diffusion (disc, well) and micro-dilution method in 96-well micro plates against twelve clinical strains of bacteria: Escherichia coli, Proteus mirabilis, Staphylococcus aureus and Enterococcus sp., Staph. aureus ATCC 25923, ATCC 6538 and E. coli 25922 and two clinical Candida albicans strains, including ATTC 10231. Spectrophotometric method was used for determination on C. albicans growth. An antimicrobial effect of EOs was strain specific. Bactericidal activity was higher for coriander EO (minimal inhibitory concentration (MICs) 0·4-45·4 μl ml(-1)) against almost all tested bacteria, except multiple resistant strains of Eneterococcus sp. and Proteus sp. Thyme EO showed slightly better fungicidal activity reaching MIC at 0·11 mg ml(-1) for all C. albicans strains. The effect of EOs on biofilm-forming ability was tested for two strains of Staph. aureus and E. coli, as well as on C. albicans filamentation ability. Brine shrimp lethality bioassay revealed thymus oil total toxicity and coriander oil intoxicity (LC50 = 2·25 mg ml(-1)). The chemical composition of oils was analysed by gas chromatography mass spectrometry showing oxygenated monoterepenes as dominant constituents. CONCLUSIONS The results provide in-vitro scientific support for the safety possible use of Coriander EO against E. coli, Staph. aureus and C. albicans vaginal infections in alternative gynaecological treatment. SIGNIFICANCE AND IMPACT OF STUDY To examine EOs as possible constituent of naturally based antimicrobial agents in vaginaletes for safety gynaecological application.

Abstract
Epithelial barrier dysfunction is important in the pathogenesis of asthma and allergic responses, and is therefore a therapeutic target. The aim of the present study was to investigate the effects of dexamethasone, a classic therapeutic agent, an anti-tumor necrosis factor agent (etanercept), which is used to treat difficult cases of asthma, and an anti-vascular endothelial growth factor (VEGF) agent (bevacizumab), which is an angiogenesis inhibitor, on zonula occludens (ZO) proteins in an experimental asthma model. The experimental model of asthma was developed using intraperitoneal (IP) and inhaled administration of ovalbumin in 38 BALB/c mice, which were divided into four groups. The control group (n=6) did not receive any treatment, while the four remaining groups (n=8 per group) received an IP injection of saline, etanercept, bevacizumab or dexamethasone, respectively. Occludin, claudin and junctional adhesion molecule (JAM) were immunohistochemically stained in the left middle lobe samples using an indirect avidin-peroxidase method, after which the staining was semiquantified with H-scores. Statistically significant differences were observed in the occludin, claudin and JAM H-scores among the four groups (P<0.001). In the untreated asthma, etanercept, bevacizumab and dexamethasone groups, the median H-scores for occludin were 93, 177, 280 and 198, respectively, while the H-scores for claudin were 82, 193.5, 274 and 202.5, respectively, and the median H-scores for JAM were 130, 210, 288 and 210, respectively. Pairwise comparisons revealed that all three ZO protein H-scores were significantly lower in the saline group when compared with each treatment group. However, the H-scores of the ZO proteins were not significantly different between the etanercept and dexamethasone groups. Furthermore, the bevacizumab group exhibited higher H-scores for all the proteins compared with the dexamethasone group. Therefore, antagonism of VEGF with bevacizumab restores the epithelial barrier to a greater extent when compared with dexamethasone treatment. This result may be promising for the development of novel therapeutic agents.

Abstract
Increased arginase activity in the airways decreases L-arginine and causes deficiency of bronchodilating and anti-inflammatory nitric oxide (NO) in asthma. As, it is suggested that L-arginine may have therapeutic potential in asthma treatment, we aimed to investigate the effects of inhaled L-arginine on oxygen saturation (SaO₂) and airway histology in a murine model of acute asthma. Twenty eight BALB/c mice were divided into four groups; I, II, III and IV (control). All groups except the control were sensitized and challenged with ovalbumin. After establishement of acute asthma attack by metacholine administration, the mice were treated with inhaled L-arginine (Group I), saline (Group II) and budesonide (Group III), respectively. SaO₂was measured by pulse oximeter just before and 5 min after methacholine. A third measurement of SaO₂was also obtained 15 min after drug administration in these study groups. Inflammation in the lung tissues of the sacrificed animals were scored to determine the effects of the study drugs. The number of eosinophils in bronchoalveolar lavage (BAL) was determined. The results indicated that inflammatory scores significantly improved in groups receiving study drugs when compared with placebo and L-arginine was similar in decreasing scores when compared with budesonide. SaO₂had a tendency to increase after L-arginine administration after acute asthma attack and this increase was statistically significant (p=0.043). Eosinophilia in BAL significantly reduced in group receiving L-arginine when compared with placebo (p<0.05). Thus in this study we demonstrated that L-arginine improved SaO₂and inflammatory scores in an acute model of asthma.

Abstract
Water management is very important in water mining regions for the sustainability of the natural environment and for industrial activities. This study focused on Acigol Lake, which is an important wetland for sodium sulphate (Na2SO4) production, a significant natural protection area and habitat for local bird species and endemic species of this saline environment, and a stopover for migrating flamingos. By a hierarchical classification method, ponds representing the industrial part were classified according to in-situ measured Baumé values, and lake water representing the natural part was classified according to in-situ measurements of water depth. The latter is directly related to the water level, which should not exceed a critical level determined by the regulatory authorities. The resulting data, produced at an accuracy of around 80%, illustrates the status in two main regions for a single date. The output of the analysis may be meaningful for firms and environmental researchers, and authorizations can provide a good perspective for decision making for sustainable resource management in the region which has uncommon and specific ecological characteristics.

Abstract
INTRODUCTION Suplatast tosilate is a medication that inhibits TH2-type cytokines. We aimed to investigate the effects of suplatast tosilate treatment and prophylaxis on lung histopathology and cytokine levels in a mouse model of chronic asthma. MATERIALS AND METHODS Forty-two BALB/c mice were divided into 6 groups: group I (control), group II (vehicle control), group III (dexamethasone), group IV (prophylaxis with suplatast tosilate), group V (treatment with suplatast tosilate), and group VI (prophylaxis and treatment with suplatast tosilate). All of the groups, except for the control and vehicle control groups, were sensitized and challenged with ovalbumin. The mice in the study groups, except those in the group receiving suplatast tosilate for prophylaxis only, were treated with study drugs. After the mice were killed, IL-4, IL-5, and interferon-γ levels were quantified in the lung tissue, which were examined histologically by light and electron microscopy. RESULTS There were significant improvements in all histopathological parameters in the group treated with suplatast tosilate compared with the vehicle control group. Similar improvements were observed when the group receiving prophylaxis and treatment with suplatast tosilate was compared with the vehicle control as well. There were no significant differences between the group receiving only prophylaxis with suplatast tosilate and the vehicle control group. Cytokine levels were significantly higher in the vehicle control group when compared with the control group. Although all of the groups had lower cytokine levels than those of the vehicle control group, the differences were not statistically significant. CONCLUSIONS Treatment with suplatast tosilate was effective in improving all histopathological parameters in a mouse model of chronic asthma. It was observed that the use of prophylactic suplatast tosilate was ineffective and had no additional effects when administered together with treatment.

Abstract
AIM: To investigate the effects of nilotinib in a rat model of trinitrobenzene sulfonic acid (TNBS)-induced colitis.
METHODS: Twenty-one Wistar albino female rats obtained from Dokuz Eylul University Department of Laboratory Animal Science were categorized into a control (n = 7), TNBS (n = 7) and nilotinib group (n = 7). Saline was administered orally for 14 d to the control and the TNBS group. The TNBS group received rectal TNBS on the first day while saline was administered to the control group. The nilotinib group received 20 mg/kg nilotinib for 14 d in 2 divided doses, starting the same day as TNBS administration. For 14 d, the rats were fed a standard diet, and their weights were recorded daily. After sacrifice, colon tissue samples from each group were scored for macroscopic and microscopic pathology. Apoptotic indices were determined by the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling method. Platelet-derived growth factor receptor (PDGFR) alpha and beta levels were assessed through immunohistochemistry staining scores and compared among the groups. Tissue and serum tumor necrosis factor (TNF) alpha levels were determined by enzyme-linked immunosorbent assay.
RESULTS: Between days 1 and 14, the nilotinib group rats lost significantly less weight than the TNBS group rats (-0.7 g vs -14.0 g, P = 0.047). The difference in weight between the control and nilotinib groups was also statistically significant (+8.3 g vs -0.7 g, P = 0.031). From day 7 to day 14, the weight differences of the control group vs the TNBS group, the TNBS group vs the nilotinib group, and the control group vs the nilotinib group were all statistically significant (+8.0 g vs -11.1 g, P = 0.007; -11.1 g vs +2.9 g, P = 0.015; +8.0 g vs +2.9 g, P = 0.042, respectively). Macroscopic and microscopic scores were significantly lower in the nilotinib group than in the TNBS group (0.00 ± 0.00 vs 1.43 ± 0.65, P = 0.009; 2.86 ± 0.55 vs 7.71 ± 1.48, P = 0.030, respectively). However, these scores were similar between the nilotinib and control groups. While no significant difference for the nilotinib vs control groups could be determined for PDGFR alpha and beta scores, PDGFR alpha and beta scores were lower in the nilotinib group than in the TNBS group. Furthermore, the TNF alpha levels in the serum, tissue and apoptosis scores were similar between the nilotinib and TNBS groups.
CONCLUSION: Nilotinib prevents weight loss, facilitates mucosal healing by improving the pathological scores without introducing variation into the apoptotic scores or TNF alpha levels.

Abstract
This longitudinal prospective study aimed to determine the prevalence of oropharyngeal colonization by C. albicans in children with cystic fibrosis (CF), and observe the continuity of candidal colonization and the changes in production of virulence factors, susceptibility to antifungal agents and RAPD patterns of the isolates. Thirty-seven children with CF were followed-up for oropharyngeal C. albicans colonization for 18 months. The colonization rate was detected in 54%. All isolates were susceptible to amphotericin B, but those isolated from one patient were resistant to fluconazole. Biofilm production, secretory acid proteinase, phospholipase and esterase activity rates were 30%, 60%, 75% and 80%, respectively. RAPD analysis with the primers OPE-03 and OPE-18 was performed for genotyping. RAPD patterns of the strains isolated from the same patient were related to each other, whereas they were not related with other strains isolated from different patients. Two C. albicans strains isolated from the same patient were found to be unrelated to one another. As a result, long-lasting colonization of the oropharyngeal mucosa of children with CF by endogenous C. albicans isolates having the same RAPD pattern was demonstrated. Colonization prevalance and development of resistance to antifungal agents and the increased production of virulence factors were not correlated.

Abstract
BACKGROUND Vascular endothelial growth factor (VEGF) is an important mediator of the neoangiogenesis component of remodeling in asthma. OBJECTIVE To evaluate the influence of VEGF blockage on airway remodeling, specifically epithelium thickness, subepithelial smooth muscle thickness, number of mast and goblet cells, and basement membrane thickness, in a mouse model of chronic asthma. METHODS We used 30 BALB/c mice. The control group was not exposed to ovalbumin or any medication (group 1). Other groups were exposed to intraperitoneal and inhaled ovalbumin to achieve chronic asthma. Each of these groups received intraperitoneal saline (group 2), intraperitoneal dexamethasone (group 3), or intraperitoneal bevacizumab (group 4). Histomorphologic examination for epithelium thickness, subepithelial smooth muscle thickness, number of mast and goblet cells, and basement membrane thickness was performed from the middle zone of the left lung. RESULTS Treatment with anti-VEGF caused significant reduction in epithelial, subepithelial muscle, and basement membrane thickness compared with untreated asthmatic mice (P = .001, P = .03, and P = .009, respectively). Goblet and mast cell numbers were significantly lower in mice treated with anti-VEGF than in untreated mice (P = .02 and P = .007, respectively). Dexamethasone treatment resulted in improvement of all histomorphologic markers, except goblet cell number. Influences of dexamethasone and anti-VEGF on epithelial and basement membrane thickness and mast and goblet cell numbers did not differ (P > .05), but subepithelial muscle layer was thinner in the former (P = .003). CONCLUSION VEGF blockage may provide adjunctive therapeutic options as steroid-sparing agents for more effective treatment of remodeling in asthma.
