Astımlı hastalarda depo akarı duyarlılığı ve ilişkili faktörler

Introduction: The aim of the study was to investigate the storage mite sensitivity and related factors in patients with asthma or asthma and rhinitis. Patients and Methods: 149 patients with asthma or asthma and rhinitis were included to the study. Prick test was performed after addition of Acarus siro (A. siro), Lepidoglyphus destructor (L. destructor), Glycophagus domesticus (G. domesticus) and Tyrophagus putrescentiae (T. putrescentiae) to the standart prick test. Living conditions, smoking history, allergic diseases status, seasonal variations in symptoms were evaluated by a questionnaire. Besides, respiratory screening spesific IgE, L. destructor spesific IgE was examined in a group of patients who were allergic to storage mites according to prick tests. Results: Prick test results showed that; 115 of the patients were sensitized while 34 of them were not. House dust mite sensitivity was detected as mite 58.3%.The storage mite sensitivity for at least one of the studied species was detected in 61.7% of patients. The sensitivity rates were 50.4%, 48.7%, 47%, %40 for A. siro, L. destructor, G. domesticus and T. putrescentiae, respectively. The storage mite sensivity was found higher in the patients from the rural areas (p< 0.05). L. destructor IgE positiveness was detected in 9.1% of the group that antibody levels were examined. Positive reaction was detected for at least one of the storage mite species in %22.7 of the patients who were considered as not sensitized according to the results of the standart prick tests. Conclusion: As a result, storage mites are important allergens in subjects who live in rural areas and close contact with barn, haymow, bin and pantry. Addition of storage mite allergens to the standart prick test panel of patients living in rural area is suitable

Mechanical Properties of Trip Aided Bainitic Ferrite TBF Steels in Production and Service Conditions

I n the automotive industry, one of the most common methods to reduce the weight of the body components is to downgage the sheets using higher strength steels. In the design phase, engineers typically use the material properties of the incoming material, such as the yield strength and the elongation. For forming analyses, however, more detailed characterization is required flow curves, anisotropy, forming limit curves, etc. . Once the components are formed in the press shop, the yield strength increases due to work strain hardening. The parts are then welded in the body shop, and the body-in-white goes to the paint shop where it is baked to cure the paint. Most steels’ yield strength changes during this paint bake cycle, which determines its final properties in service. Bake hardening and in some cases, bake softening is measured by Bake Hardening Index BHI as defined by EN 10325-2006. The standard dictates relatively low pre-strain 2% and baking temperature 170°C . In real production conditions however, higher strains are achieved and baking temperatures may exceed 170°C to shorten the baking time. In this study, a new generation Advanced High Strength Steel AHSS grade TBF 1050 was characterized for metal forming purposes and its bake hardening response was studied both as the standard suggests and as the real production cycle dictate

Composition of the essential oils of five subspecies of Scutellaria orientalis from Turkey

The chemical compositions of the essential oils obtained by hydrodistillation from aerial parts of five subspecies of Scutellaria orientalis L. (subsp. carica, subsp. haussknechtii, subsp. macrostegia, subsp. orientalis and subsp. santolinoides) were analyzed by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS), simultaneously. According to essential oil analysis in five subspecies of S. orientalis, germacrene D (57.2%), bicyclogermacrene (7.4%) and β-caryophyllene (5.2%) in subsp. carica; germacrene D (23.5%), β-caryophyllene (14.2%), bicyclogermacrene (9.0%) and caryophyllene oxide (8.1%) in subsp. haussknechtii; germacrene D (47.8%), β-caryophyllene (16.3%) and bicyclogermacrene (12.0%) in subsp. macrostegia; caryophyllene oxide (23.5%), germacrene D (20.1%) and β-caryophyllene (14.5%) in subsp. orientalis; germacrene D (42.1%), β-caryophyllene (13.7%) and bicyclogermacrene (11.3%) in subsp. santolinoides were determined as major components. To the best of our knowledge, this is the first report on the chemical composition of the essential oil of four subspecies of S. orientalis. © 2020 Informa UK Limited, trading as Taylor & Francis Group

Assessment of patient satisfaction with evaluation methods in open technique septorhinoplasty

WOS: 000374761200079PubMed ID: 26967078The aim of this study was to measure the postoperative satisfaction of patients who underwent open technique septorhinoplasty (SRP) using Nasal Obstruction Symptoms Evaluation (NOSE), Rhinoplasty Outcomes Evaluation (ROE) and visual analog scale (VAS), and to assess the reliability and usability of these forms in the outcome of SRP. Forty-five patients who underwent primary open technique SRP were included in the study. The levels of patient satisfaction were assessed before the surgery and in the long-term using NOSE, ROE, and VAS. Nasal Obstruction Symptoms Evaluation scores were found to be decreased significantly after surgery, whereas ROE scores were increased postoperatively (P 0.05). There was a statistically significant positive relationship between ROE difference before and after surgery, and functional VAS difference (r = 0.544, P = 0.001). There was a positive correlation between pre-postoperative ROE difference, and aesthetic VAS difference (r = 0.766, P = 0.001). The relationship between the pre-postoperative NOSE score difference and functional VAS difference was found to be significantly negative (r = -0.833, P = 0.001). The relationship between pre-postoperative NOSE difference and aesthetic VAS difference was also significantly negative (r = -0.475, P = 0.001). There was a significant negative correlation between ROE difference between before and after surgery, and NOSE difference (r = -0.640, P = 0.00). The disease-specific quality of life assessment forms used to evaluate patient esthetic and functional satisfaction correlate significantly with nasal obstruction and ROE

Essential oil compositions of subspecies of Scutellaria brevibracteata Stapf from Turkey

The essential oils obtained by hydrodistillation from the aerial parts of three subspecies of Scutellaria brevibracteata (subsp. brevibracteata, subsp. subvelutina and subsp. pannosula) collected from their natural localities in Turkey were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS), simultaneously. On the basis of chromatographic analysis and data analyzed, β-caryophyllene (22.8%) and caryophyllene oxide (16.0%) were determined as the main components in S. brevibracteata subsp. brevibracteata oil. In S. brevibracteata subsp. subvelutina oil, β-caryophyllene (28.3%), linalool (12.4%) and hexadecanoic acid (10.8%) were found as major constituents. β-Caryophyllene (36.4%), α-cadinol (9.8%), δ-cadinene (7.0%) and linalool (5.3%) were identified as major components in the oil of S. brevibracteata subsp. pannosula. To the best of our knowledge, this is the first report on the chemical composition of the essential oils of three subspecies of Scutellaria brevibracteata. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group
