Evaluation of volumetric measurements on CBCT images using stafne bone cavities as an example
2015
Adisen, Mehmet Zahit/0000-0002-5493-8390; Yilmaz, Selmi/0000-0001-9546-6548; Yilmaz, Selmi/0000-0001-9546-6548; ATIL, Fethi/0000-0002-8286-4819 WOS: 000365269900009 PubMed: 26116844 Background: The aim of the present study is to evaluate the efficacy of CBCT in volume measuring using Stafne Bone Cavities (SBC) as an example. Material and Methods: The study was conducted with 14 subjects with SBC detected on panoramic radiographs. In order to evaluate lesions volumetric dimensions, CBCT images for each patient were captured. Files in Digital Imaging and Communications in Medicine (DICOM) format were transferred into a medical image processing program (ITK-SNAP 2.4.0) and volume in mm(3) of t…
Comparing indirect methods of digit ratio (2D:4D) measurement.
2008
The ratio of the lengths of the second and fourth finger (2D:4D) has been proposed to index prenatal exposure to androgens. Different methods have been utilized to measure digit ratio, however, their measurement precision and economy have not been systematically compared yet. Using different indirect methods (plastic ruler, caliper, computer software), three independent raters measured finger lengths of 60 participants. Generally, measurement precision (intraclass correlation coefficient, technical error of measurement, and relative technical error of measurement) was acceptable for each method. However, precision estimates were highest for the computer software, indicating excellent measur…
Comparison of RNA-seq and microarray-based models for clinical endpoint prediction
2015
Background Gene expression profiling is being widely applied in cancer research to identify biomarkers for clinical endpoint prediction. Since RNA-seq provides a powerful tool for transcriptome-based applications beyond the limitations of microarrays, we sought to systematically evaluate the performance of RNA-seq-based and microarray-based classifiers in this MAQC-III/SEQC study for clinical endpoint prediction using neuroblastoma as a model. Results We generate gene expression profiles from 498 primary neuroblastomas using both RNA-seq and 44 k microarrays. Characterization of the neuroblastoma transcriptome by RNA-seq reveals that more than 48,000 genes and 200,000 transcripts are being …
Application of mtDNA sequence analysis in forensic casework for the identification of human remains
2000
Abstract In four forensic cases of unidentified skeletal remains investigated in the last year, we were able to attach three to missing persons. In one case we could show that the discovered bone sample did not fit to a missing child. The method for mitochondrial DNA analysis for the routine identification of skeletal remains was established in our institute by typing bone samples of defined age obtained from Frankfurt's cemetery. Reproducible results were obtained for bones up to 75 years old. For analysis the bone samples were pulverised to fine powder, decalcified and DNA was extracted. From the DNA we amplified a 404-bp fragment from HV-1 and a 379-bp fragment from HV-2 of the mtDNA con…
Estimation of the age of majority through radiographic evaluation of the third molar maturation degree
2020
Background Although the third molar is the tooth with the greatest anatomical and developmental variability, some authors consider it important to estimate whether a subject is of legal age or not. The Demirjian’s technique is the most widely used tool to estimate dental age and was therefore used in our study to assess possible correlation between the age of majority and the maturational degree of the lower third molars, evaluated through radiographic images. Material and Methods This observational transversal study was conducted on 180 panoramic radiographs from consecutive patients. The degree of maturation of the lower third molar was independently classified by two observers, according…
Effectiveness of lingual versus labial fixed appliances in adults according to the Peer Assessment Rating index.
2019
Introduction: The purpose of this study was to compare the effectiveness of lingual treatment and labial fixed appliances in the treatment of adult orthodontic patients. Methods: We conducted a retrospective study of 72 patients. The Peer Assessment Rating (PAR) index was measured at the start (T0) and end (T1) of treatment. Significant differences between treatment means were determined by means of analysis of variancewith the Bonferroni correction or with the use of Fisher exact test. Results: The lingual group had a mean pretreatment age of 28.6 ± 6.7 years, and the labial group had a pretreatment age of 26.6 ± 9.5 years. This difference was statistically not significant. The mean pre- a…
Defining response and remission in psychotherapy research: A comparison of the RCI and the method of percent improvement
2011
There is no consensus as to how to define response and remission for mental disorder treatments. The Reliable Change Index (RCI) is most commonly used in psychotherapy research, whereas psychopharmacologists prefer to calculate percentage of improvement (PI). We compared both methods using the Beck Depression Inventory in 395 depressive outpatients. The overall pre-post effect size was d=1.18. The PI-50 (≥ 50% improvement from baseline) resulted in outcome estimates higher than the RCI: 66.3% vs. 59.2% for response and 50.6% vs. 45.8% for remission. We demonstrate that the PI approach is independent of arbitrarily chosen reliabilities and reference populations. Furthermore, it takes differe…
Daily eudaimonic well-being as a predictor of daily performance: A dynamic lens.
2019
Sustaining employees' well-being and high performance at work is a challenge for organizations in today's highly competitive environment. This study examines the dynamic reciprocal relationship between the variability in office workers' eudaimonic well-being (i.e., activity worthwhileness) and their extra-role performance. Eighty-three white-collar employees filled in a diary questionnaire twice a day, once in the morning and once in the afternoon, on four consecutive working days. The results show that eudaimonic well-being displays clear variability in a short time frame. In addition, Bayesian Multilevel Structural Equation Models (MSEMs) reveal a significant positive relationship between…
Statement of severe trauma management in France; teachings of the FIRST study
2013
Abstract Introduction The blunt trauma victim management is still a matter of debate and comparing studies involving different emergency medical services and health care organization remains fictitious. Hence, the French Intensive care Recorded in Severe Trauma (FIRST) was conducted in order to describe the severe blunt trauma management in France. The present paper aimed at recalling the main results of FIRST study. Methods The FIRST study was based on a multicenter prospective cohort of patients aged 18 or over with severe exclusive blunt trauma requiring admission to university hospital care unit within the first 72 h and/or managed by medical-Staffed Emergency Mobile Unit (SMUR). Multip…
Blood pressure for outcome prediction and risk stratification in acute pulmonary embolism.
2015
Abstract Introduction Risk stratification of patients with acute pulmonary embolism (PE) is crucial in deciding appropriate therapy management. Blood pressure (BP) is rapidly available and a reliable parameter. We aimed to investigate BP for short-term outcome in acute PE. Materials and methods Data of 182 patients with acute PE were analyzed retrospectively. Logistic regression models were calculated to investigate associations between BP and in-hospital-death as well as myocardial necrosis. Moreover, receiver operating characteristic (ROC) curves and cutoff values for systolic and diastolic BPs predicting in-hospital death and myocardial necrosis were computed. Results A total of 182 pati…
