Abstract

Abstract Background Schizophrenia is a multifactorial disease involving interactions between genetic and environmental factors. Vitamin D has recently been linked to many metabolic diseases and schizophrenia. Vitamin D plays essential roles in the brain in the context of neuroplasticity, neurotransmitter biosynthesis, neuroprotection, and neurotransmission. Vitamin D receptors are demonstrated in most brain regions that are related to schizophrenia. However, very few studies in the literature examine the effects of 25-hydroxyvitamin D (25OHD) on schizophrenia symptoms. Methods This study aimed to examine the effects of vitamin D replacement on positive, negative, and cognitive symptoms of schizophrenia. Serum 25OHD levels of 52 schizophrenia patients were measured. SANS and SAPS were used to evaluate the severity of schizophrenia symptoms, and the Wisconsin Card Sorting Test: CV4 was used for cognitive assessment. The study was completed with 40 patients for various reasons. The patients whose serum 25OHD reached optimal levels after vitamin D replacement were reevaluated with the same scales in terms of symptom severity. The SPSS 25 package program was used for statistical analysis. The Independent-Samples t-test was used to examine the relationship between the variables that may affect vitamin D levels and the vitamin D level and to examine whether vitamin D levels had an initial effect on the scale scores. Results The mean plasma 25OHD levels of the patients was 17.87 ± 5.54. A statistically significant relationship was found only between the duration of sunlight exposure and 25 OHD level (p

Abstract

Purpose: Investigate the effects of three different complete-arch digital implant scanning techniques used with a combined healing abutment–scan body (CHA-SB) system on the accuracy (trueness and precision) and scan time. Materials and Methods: A poly(methyl methacrylate) master model simulating an edentulous maxilla was fabricated with four parallelly inserted dental implants. A CHA-SB system was attached to each implant. The model surface was scanned using a structured blue light industrial extraoral scanner to achieve a reference model standard tessellation language file (MRM-STL). Three different scanning techniques—(1) conventional technique with unmodified master model, (2) scan body splinting technique using orthodontic elastic ligatures and plastic splint materials, and (3) land-marking technique using pyramid-shaped glass-ceramic markers—were performed. Fourteen consecutive digital scans were made by using an intraoral scanner (IOS) for each technique, converted to an STL file, and superimposed on the MRM-STL. Trueness and precision were calculated for each technique. The scan time was also recorded. The data were analyzed with one-way analysis of variance (ANOVA) and Tukey honest significant difference (HSD) tests (α = .05). Results: Effects of different scanning techniques on the trueness (distance and angular deviations; P < .001) and scan time (P = .002) were statistically significant. For precision, different scanning techniques had only a significant effect on the distance deviation (P < .001). Conclusion: Regarding trueness and precision, none of the scanning techniques was superior to others. The scan body splinting technique led to significantly less scan time. [ABSTRACT FROM AUTHOR]

Abstract

Objective: Laryngoscopy and intubation cause hypertension, tachycardia and arrhythmia. Ischemia modified albumin (IMA) is formed secondary to endothelial or extracellular hypoxia, acidosis and free oxygen radicals and can be detected in the early stages of ischemia. In this study, we aimed to compare the effects of two agents on preventing hypertension and tachycardia by measuring IMA levels. Methods: Following ethics approval and randomization, dexmedetomidine 0.5 μg kg-1 in Group D (n=21) or esmolol 0.5 mg kg-1 in Group E (n=21) diluted in 20 mL saline was given as infusion for 5 minutes prior to induction. Patients in Group C (n=21) received only 20 mL saline infusion. An automated perfusor was set at 4 mL min-1 for the delivery of study solutions. Blood samples for IMA measurement were taken following monitorization and at 10th and 20th minutes after intubation. Results: There was no statistically significant difference concerning IMA levels at 10 minutes following intubation. However, IMA levels in Group C were significantly lower compared to Group E and Group D (p=0.025 and 0.015 respectively) at 20 minutes. There was no significant difference between Group E and Group D (p=0.980). In Group D and E, a significant drop in systolic, diastolic and mean arterial pressures compared to baseline was observed after the study drugs were given. Groups were similar in terms of heart rate in the first 5 minutes however Groups E and D had lower heart rates compared to Group C starting from the 6th minute until the end of study period. Conclusion: Inhibiton of hemodynamic response to intubation may have negative results, and pharmacological interventions for this should be carried out with caution in critical patients and close hemodynamic monitorization should be kept in mind.

Abstract

(i) Objective: Changes in the mesiodistal axial angulations of teeth with orthodontic treatment have been a topic of interest in orthodontics for many years, although it has not been clarified enough yet. Therefore, this present study aimed to compare mesiodistal axial angulations of canine and first molar teeth by measuring from pre- and post-treatment panoramic radiographs in different types of orthodontic malocclusions. (ii) Materials and Methods: In the study, the mesiodistal axial angulation angles of the lower–upper canines (teeth numbered 13, 23, 33, and 43) and first molars (teeth numbered 16, 26, 36, and 46) were compared on panoramic radiographs taken pre- (T0) and post- (T1) orthodontic treatment of 353 patients: 237 female (mean age 14.74 ± 2.96) and 116 male (mean age 14.44 ± 2.50), who had not received any prior orthodontic treatment. The groups were formed according to pre-/post-treatment, gender, angle classification, skeletal classification, bilaterally first premolar extraction/non-extraction, and the use/non-use of miniscrews in the extraction cases. The mesiodistal angulations between the long axes of both the lower and upper canines and first molars and the interorbital plane were measured separately and recorded. The reliability analysis between the repeated measurements was evaluated using the intraclass correlation coefficient (ICC). For statistical analysis, a paired sample t-test and Wilcoxon test were used for the normally and non-normally distributed data, respectively. For the between-groups comparison, independent sample t-test and one-way ANOVA were used for normally distributed data, while the Mann–Whitney U and Kruskal–Wallis tests were used for non-normally distributed data. A value of p < 0.05 was considered statistically significant. (iii) Results: ICCs showed excellent reliability, ranging from 0.804 to 0.913 in other teeth, yet were good in tooth 43 (ICC = 0.712). Regardless of the groups, statistically significant differences were found between the T0 and T1 angulations for all teeth, except teeth 13 and 16. In all groups, the increase in the angulations of teeth 33 and 43 and the decrease in the angulations of teeth 36 and 46 (except skeletal class 3) were found to be statistically significant. The T0 and T1 angulation changes in the miniscrews in the used and non-used groups in extraction cases were similar to the differences found in all teeth, regardless of the groups. There was no significant difference between gender, skeletal classes, and angle classes in the amounts of change in the mesiodistal angulations. (iv) Conclusion: It was concluded that orthodontic treatment caused significant changes in the mesiodistal axial angulation of the canine and the first molar teeth. Furthermore, the fact that the angulations tended to increase in the lower canine teeth and decrease in the lower first molar teeth revealed the importance of tooth movement control, especially in orthodontic mechanics in the mandibula.

Abstract

Studies have shown the effect of the operator and scanned areas on the accuracy of single implant scans. However, the knowledge on the scan accuracy of the remaining dental arch during single implant scans, which may affect the occlusion, is limited. The aim of this study was to investigate the effect of scanned areas and the operator on the scan accuracy of a dentate arch while scanning a single implant. A dentate model with an anterior implant was digitized with a laboratory scanner (reference scan). Three operators with similar experience performed 10 complete- and 10 partial-arch scans (left 2nd molar to right canine) with an intraoral scanner (TRIOS 3), and these scans were superimposed over the reference. The accuracy was analyzed at 22 points in complete-arch and at 16 points in partial-arch scans on 2nd molars and incisors. Data were evaluated with 2-way ANOVA and Tukey HSD tests (α = 0.05). The trueness of the total scanned area was higher in partialthan in complete-arch scans (p < 0.001). The trueness and precision of the scans were higher in the anterior site compared with the posterior in complete- (trueness: p ≤ 0.022, precision: p ≤ 0.003) and partial-arch (trueness: p ≤ 0.016, precision: p ≤ 0.016) scans of each operator and when the operator scan data were pooled. The complete-arch scan’s precision was not influenced by the operator (p ≥ 0.029), whereas the partial-arch scans of operator 1 and 2 were significantly different (p = 0.036). Trueness was higher in partial- compared with complete-arch scans, but their precision was similar. Accuracy was higher in the anterior site regardless of the scan being a partial- or a complete-arch. The operator’s effect on the accuracy of partial- and complete-arch scans was small. 35887889

Abstract

İslami finans sektöründeki büyüme ve küreselleşme beraberinde şirket düzeyinde kurumsallaşma ve ulus-devlet düzeyinde düzenleme ve denetleme çabalarını getirmektedir. Modern kurumsal yönetim teorilerinin İslami finans kurumları için yetersiz kalması sonucu yeni bir yapılaşma ihtiyacı doğmuştur. İslami kurumsal yönetim bu ihtiyaç doğrultusunda, modern kurumsal yönetim yapısına danışma komiteleri yapısı eklenerek oluşturulmuştur. Özellikle İslami finans kuruluşlarında ortaya çıkan bu yapı, sunulacak ürünlerin İslam hukukuna uygunluğu konusunda fikir veren bir oluşumdur. Kurum bazlı danışma komiteleri haricinde ulusal düzeyde de merkezi danışma kurulları kurulmuş ve İslami finansın standartlaşması amaçlanmıştır. Bu çalışmada Bangladeş, Malezya, Endonezya, Birleşik Arap Emirlikleri, Umman ve Türkiye özelinde merkezi danışma kurulları incelenmiştir. Çalışmanın daha rahat anlaşılabilmesi ve ülkelerin birbirleri ile kıyaslanmasında kolaylık sağlaması açısından üç ana parça halinde incelemeler gerçekleştirilmiştir. İslami finans ile ilgili ülkelerin çıkarmış oldukları yasalar, merkezi danışma kurullarının yapıları ve kurum bazlı danışma kurullarının yapıları ülkeler için ayrı ayrı ele alınmıştır. Merkezi siyasi otorite, sivil toplum ve özel sektör arasındaki güç ilişkileri ve siyasi yapıyı oluşturma şekilleri ülkeden ülkeye değiştiği için farklı Müslüman toplumlarda Şer’i yönetim çerçevesinin farklı yapılarda oluştuğu görülmektedir. Bu bağlamda çalışmanın son kısmında incelenen ülkelerin siyasi otorite, sivil toplum ve özel sektör güç dengeleri arasında nereye konumlandığına dair bir sınıflama teklif edilmektedir.
