Introduction: Dental fear is one of the most common problems in dentistry, for both the patient and for the dentist. This issue can have an important effect on an individual’s dental health. Aim: The aim of this paper was to report on the prevalence of dental anxiety and to explore if high levels of anxiety are associated with sociodemographic factors, oral health status, and level of oral health awareness. Materials and Methods: The sample for this cross-sectional study included 294 patients (154 males and 140 females). All participants filled out a Dental Fear Survey (DFS) to evaluate their level of dental fear. Gender, age, education level, socioeconomic status and oral health awareness were also noted. Oral health behaviors and oral health awareness levels were investigated using seven questions. Also, the periodontal status of all participants was evaluated using the Community Periodontal Index of Treatment Needs (CPITN). Differences between different subgroups were tested using the chi-square test. Results: There was a statistically significant difference between the DFS groups with regard to sociodemographic data. Women had significantly higher scores than men, and young patients had significantly higher scores than others. Patients with low education levels and low socioeconomic status had high DFS scores. Periodontal status was better in groups that had scores in the low and moderate ranges compared to groups that had high scores on the DFS. There was a statistically significant difference between the groups of DFS and CPITN (p<0.05). Patients with low and moderate levels of DFS answered the oral health knowledge questions correctly.There was a statistically significant difference between the DFS groups based on correct answers to the oral health knowledge questions (p<0.05). Conclusion: The elimination of dental fear is very important and should be treated according to a patient-centered assessment. These individuals were informed about the dental treatment procedure so their prejudices were eliminated. Patients with a high level of dental fear may be given psychiatric support for comfortable treatment procedure. © Copyright 2007-2016, Journal of Clinical and Diagnostic Research, India.

In this study, the relationship between the hourly changes of the ionospheric critic frequency values of F2 layers in low latitudes and geomagnetic activity is examined by using statistical methods. The ionospheric critical frequency data has been taken from the Manila (121.1° E, 14.7° N) ionosonde station. In order to investigate the effect of sun activity on ionospheric critical frequency, the data of 1981 when the sun was active and of 1985 when the sun was less active has been used. According to the Granger causality test results, on 5 % significance level, a causality relationship from disturbance storm time (Dst) index values to ionospheric critical frequency values direction has been observed. However, a causality relationship from ionospheric critical frequency values to Dst values has not been observed. From the results of cause-and-effect analysis, it is evaluated that the effect of a shockwave occurring in geomagnetic activity on ionospheric critical frequency continues along 72 h, that is, geomagnetic activity has a long-term effect on ionospheric critical frequency. The response of ionospheric critical frequency to geomagnetic activity substantially depends on seasons. This response is more observed especially in equinox period when the sun is active and in winter months. The increase in geomagnetic activity causes ionospheric critical frequency to decrease in night hours and increase in day hours. The same relationship has not been observed exactly, though observed very little in winter months, for 1985 when the sun was less active. © 2013, Saudi Society for Geosciences. Source

In this paper, we study S – tangent surfaces according to Sabban frame in the Lorentzian Heisenberg group H. We obtained differential equations in terms of their geodesic curvatures in the Lorentzian Heisenberg group H. Finally, we found explicit parametric equations of one parameter family of S – tangent surfaces according to Sabban Frame. © 2014, Eduem - Editora da Universidade Estadual de Maringa.

Our objective was to determine the effects of the Trigonella foenum-graecum seed extract and chromium picolinate in streptozotocin (STZ) induced diabetes in rats. We used 60 female Sprague Dawley rats aged between 2-3 months, who were divided into 6 groups: control (C);vehicle received physiological saline solution intraperitoneally (i.p.) + physiological saline solution orally, diabetescontrol group (DC); 50 mg/kg STZ i.p. + physiological saline solution orally, T. foenum-graecum (TFG); 50 mg/kg STZ i.p + 150 mg/kg TFG seed extract orally, chromium picolinate (Crpic); 50 mg/kg STZ i.p + 30 μg/kg Chromium picolinate orally, T. foenum-graecum + chromium picolinate (TFG+Crpic); 50 mg/kg STZ i.p. + received 150 mg/kg TFG + 30 μg/kg Crpic orally, insulin (I); 50 mg/kg STZ i.p. + 1 IU insulin subcutaneously. The treatment lasted for 21 days. On the 14th and 21st days, we found a decrease in the FBG of animals treated with insulin, TFG, TFG + Crpic combined (all p < 0.001), and Crpic (p < 0.01) compared with the diabetes control group. Moreover, there was a significant decrease in the plasma triglyceride and very low density lipoprotein (VLDL) levels after a treatment with Crpic, I, TFG, and TFG+Crpic compared with diabetes control group (p < 0.001). Administration of TFG+Crpic caused a significant increase in plasma high density lipoprotein (HDL) levels (p < 0.05) compared with diabetes control group. There was a significant decrease in the plasma tumor necrosis factor alpha (TNF-α) level after a treatment with Crpic (p < 0.05). The TFG, TFG and Crpic combined, and insulin treatment significantly increased the insulin-positive β cells compared with diabetes control group (p < 0.001). These results show that the TFG extract may have an insulinotropic effect on the β cells of the islets of Langerhans, or may prevent the damage of the pancreatic β cells. Crpic did not stimulate insulin secretion from the β cells in the Langerhans islets. We concluded that Crpic may exert its antihyperglycemic effects by facilitating the interaction between insulin and its receptor. It is recommended that the TFG seed extract and Crpic supplements may help in alleviating or reducing the hyperglycemia-related chronic complications of diabetes. © 2016, National Institute of Science Communication and Information Resources (NISCAIR).

This experiment was performed to investigate the effect of dietary supplementation with olive leaf extract on some blood parameters and egg yolk fatty acid composition of laying quails. A total of 192 Japanese quail (Coturnix coturnix japonica) 60 d old were allocated to 4 treatment groups with 4 replicates each containing 12 birds. Birds housed in cages and water and feed were given ad libitum during the total period of experiment. The quails received a basal diet (maize and soyabean meal based; 19.1% CP, 2.940 kcal/kg ME, 3.0% Ca and 0.39% P av) that was formulated including vitamins and minerals. Diets were prepared as control (basal diet, group Control), basal diet plus 200 mg α-tocopherol acetat/kg (group E), and basal diet plus 80 or 120 ppm Oleuropein (OLE) (group OLE-80 and OLE-120). At the end of the experiment, egg yolks samples were analysed; cholesterol levels of groups fed diets with OLE-80 and OLE-120 were significantly higher than the groups fed control diet (p<0.01); vitamin A levels of groups fed diets with vit. E were significantly lower than the groups fed control diet and containing OLE-80 (p<0.05) and vitamin E levels were significantly higher than the other groups (p<0.001). The supplementation of olive leaf extract were influenced to fatty acid composition of egg yolk lipids. The concentration of oleic and linoleic acids in egg yolks were higher in OLE-80 than the others groups (p<0.05). The concentration of PUFA, n-6 fatty acids and n-6/n-3 fatty acids ratio were the highest in OLE-80 groups than the other groups. These results showed that the supplementation of 80 ppm OLE in quail diets was conducted to increase of oleic, linoleic and n-6 fatty acids, and n-6/n-3 fatty acids ratio in egg yolks. © 2016, Chartered Inst. of Building Services Engineers.
