Ortodontik malokluzyonlar ve tedavilerinin havayolu boyutlarına, dil ve hyoid kemik konumuna etkisi

Tongue and hyoid bone position, due to the muscle attachments surrounding them and the airway dimensions, depending on the structures that surround them are affected by the relationship of the maxilla and mandible. The malocclusions that influence the relationship between maxilla and mandible and the treatments of these malocclusions can change the airway dimensions, tongue and hyoid bone positions. İn this article, we will summarize how and to what extent that these structures are affected by various malocclusions and from the treatments of these malocclusions.Keywords: Malocclusion, orthodontic treatment, tongue position, airway dimension, hyoid position. ÖZET Dil ve hyoid kemiğin pozisyonu, bağlı olduğu kas ataçmanları itibariyle; havayolu boyutları da kendisini çevreleyen yapılar itibariyle maksilla ve mandibulanın ilişkisinden etkilenir.

CFD Modelling of Two Different Cold Stores Ambient Factors

AbstractObjective of the research was to determine ambient temperature and relative humidity distributions of two different cold stores which have two different cooling systems. One of the cold store which is called as Cold store-I, has classical cooling system such as compressor, condenser and evaporator. Second called Cold store-II, has air conditioning system for cooling, cold air ventilation and aspiration systems, and humidification system. Computational fluid dynamics was used for modelling of distribution of temperature and relative humidity of cold store walls. Storage temperature and relative humidity were assumed 2°C and 90%, respectively. Boundary conditions were set as; Inlet-Surface of fluid inlet, Outlet-Surface of fluid outlet, and walls-solid, proof against flow of fluid. A tetrahedral mesh was created by using ANSYS 14.0 and calculation finished when accessing a solution. Turbulence was modelled using the k-ɛ (k-epsilon). Spatial distribution in two cold stores for two different cooling systems were modelled and evaluated in this research. Data determined from CFD models were compared for both cold stores. Cold store-II was better than Cold store-I because it has air distribution holes located on ceiling

Dudak damak yarıklı bireylerin kendini-kabul düzeylerinin değerlendirilmesi

Purpose: To survey the self acceptance of cleft lip and palate (CLP) individuals. Material and Methods: This study consisted of 34 patients with age range of 11-16 from the Department of Orthodontics of Faculty of Dentistry at Cumhuriyet University. Study sample was divided into 2 groups. The first group consisted from 14 individuals with CLP and the second group includes 20 individuals without CLP. The data of the study obtained with “Self-Acceptance Inventory”. We used Mann- Whitney U Test to compare the Self Acceptance of both groups. Results: There were significant differences between the Self Acceptance of study and control groups (p< 0, 05). Conclusion: Beside aesthetic operations performed on CLP patients we should not neglect psychologic status of these patients. Also we should support and psychologically rehabilitate the parents of these patients. ÖZET Amaç: Dudak damak yarıklı (DDY) çocukların kendini kabul düzeyleri yönünden incelenmesi. Gereç ve Yöntem: Çalışmamız Cumhuriyet Üniversitesi, Diş Hekimliği Fakültesi, Ortodonti anabilim dalında tedavi gören ve yaşları 11 ile 16 arasında değişen toplam 34 hasta üzerinde yürütülmüştür. Hastalar iki guruba ayrılmış, birinci gurup 14 DDY’li bireyden, ikinci grup ise 20 adet sağlıklı bireyden oluşturulmuştur. Çalışmamızda veriler “Kendini Kabul Envanteri” ile toplanmıştır. Grupların kendini kabul düzeyi açısından karşılaştırılmasında Mann- Whitney U Testi kullanılmıştır. Bulgular: Deney ve kontrol gurubu kendini kabul düzeyi açısından karşılaştırıldığında, gruplar arasında fark anlamlı bulunmuştur (p<0,05). Sonuç: DDY’li bireylerin dış görünüşlerini düzeltmek için yapılan operasyonların yanı sıra psikolojik yapıları da ihmal edilmemelidir. Ayrıca DDY’li çocuğa sahip ebeveynler de çeşitli şekilde moral ve destek rehabilitasyonlarına tabi tutulmalıdır. Anahtar Kelimeler: dudak damak yarığı, kendini kabul, psikolojik duru

Bearing and Swelling Properties of Randomly Distributed Waste Jute Reinforced Soil

In this study, waste jute, which was provided from textile companies, was investigated to define effect of waste jute on swelling and bearing behavior of the sand used. Three different water content (17, 19 and 21%) and four different waste jute addition amount at different percentages (0, 1, 2, and 3) by mass of dry soil were selected as design variables. With defined variables Swelling Ratio and California Bearing Ratio (CBR) tests were conducted. According to test results it is concluded that minimum swelling ratio was observed in the test containing 3% jute with 19% water content and the highest value of CBR was observed in the sample containing 2% jute with 16% water content. In addition to that, CBR values of unreinforced samples were decreased when water content increased from 16% to 21%. However, CBR values of reinforced samples increased with increasing water content from 19% to 21%

Pregnancy-related carpal tunnel syndrome; non-invasive early diagnosis and postpartum evaluation

The diagnosis of pregnancy-related carpal tunnel syndrome (PRCTS) was made with noninvasive methods and evaluated the effect of PRCTS on quality of life, its treatment and prognosis. Third-trimester pregnant women between the ages of 18-45 and diagnosed with PRCTS were included. For diagnosis; the presence of pain, positive motor and sensory tests, Carpal Tunnel Symptoms Scale-6 (CTS-6), and Boston Carpal Tunnel Questionnaire (BCTQ) were evaluated. The criteria used to determine improvement were the regression of complaints and symptoms based on a VAS score of 0 and a CTS-6 score of less than 5. According to these criteria, patients whose complaints regressed in the postpartum eighth week were called group A, whose complaints regressed in the postpartum sixth month were called group B, and women who still did not meet the criteria were called group C. The study included 102 wrists of 94 women. When the type of delivery, gestational age at birth, gravida, and parity were compared according to the continuity of complaints and symptoms, no differences were found. When the first trimester body mass index (BMI) measurements were compared between groups A and B, it was observed that group B had higher first trimester BMI values; this difference was statistically significant. The mean age was 29.2 years in group A, was 32.6 years in group B and the difference was significant. Conclusions: We recommend that pregnant women over 30 years old with a high BMI should be screened for PRCTS using non-invasive diagnostic tools, CTS-6, and VAS. [Med-Science 2023; 12(1.000): 70-5

Effects of nicorandil on renal function and histopathology in rats with partial unilateral ureteral obstruction

To evaluate the effects of nicorandil in a rat kidney model of partial unilateral ureteral obstruction (PUUO). Thirty male rats were randomly divided into three groups as follows: (1) Group 1 (Sham-control), ureters of the rats were manipulated but not ligated; (2) Group 2 (PUUO-untreated), PUUO was performed with two-thirds of the left ureter embedded in the psoas muscle; and (3) Group 3 (PUUO-nicorandil treated). After PUUO was established, nicorandil (15 mg/kg/day) was administered by gastric lavage for 21 days to determine its effects on PUUO-induced histopathological-, functional-, and oxidative stress-induced changes. The serum levels of blood urea nitrogen and creatinine were reduced in Group 3. The level of urinary albumin and the ratio of urinary protein/creatinine were increased in the kidneys of Group 2 but decreased in Group 3. Malondialdehyde value was decreased in Group 3 compared with Group 2. Antioxidant enzyme activities (catalase, superoxide dismutase, and glutathione peroxidase) were decreased in Group 2. Nicorandil treatment caused an increase in these enzyme activities. In Group 3, leukocyte infiltration and tubular dilatation were significantly reduced. Other parameters, such as degeneration of tubular epithelium and fibrosis, also showed a marked improvement in Group 3. Expression of inducible nitric oxide synthase in Group 2 and expression of endothelial nitric oxide synthase in Group 3 were significantly elevated. Nicorandil can inhibit renal tubular damage and tubulointerstitial fibrosis by reducing the effects of oxidative stress after PUUO
