    The aim of this study was to investigate the efficiency of different diagnostic methods in detection of residual dentinal caries in excavated cavities. Fifty extracted molar with deep dentinal carious lesions were excavated using a slow-speed handpiece. All cavities were assessed by laser fluorescence(LF) device, electronic caries monitor(ECM), and caries detector dye(CDD) by three independent observers blindly. The measurements were repeated after two weeks. Specimens containing dentin slices 150 μm in thickness were prepared for histological analyses. The existence and absence of carious dentin was determined using a lightmicroscope. The average intraobserver accuracy was 1.00 (perfect agreement) for CDD, 0.86 (excellent agreement) for ECM, and 0.50 (good agreement) for LF. The average interobserver accuracy values were 0.92 (excellent agreement), (0.36 marginal agreement) and 0.48 (good agreement), for CDD, ECM, and LF, respectively. The average specificity was 0.60 for CDD, 73% for ECM, and 0.50 for LF. The average sensitivity was 0.55 for CDD, 0.85 for LF, and 0.47 for ECM. The average accuracy values were 0.53, 0.51, and 0.81 for CDD, ECM, and LF, respectively. LF had the greatest sensitivity and accuracy values of any of the methods tested. As a conclusion, LF device is appeared to most reliable method in detection of remain caries in cavity. However, because of its technical sensitivity it may susceptible to variations in measurements. To pay attention to the rule of usage and repeated measurements can minimize such variations in clinical practice. It was concluded that LF is an improvement on the currently available aids for residual caries detection

    How website users segment a city: The geography of housing search in London

    This paper explores spatial patterns of housing search in London, using data generated by users of the UK's most popular real estate portal. By focusing on the variable geographies of ‘search extent’, it attempts to make a contribution to a long line of studies focused on understanding the fragmented geography of metropolitan housing markets. It also builds upon more recent work in economics on the utility of user-generated search data. After introducing our approach, we discuss the background to housing search and the wider emergence of ‘search’ as an object of study. We then provide further details on the data and methodology before exploring the spatial and sectoral characteristics of search in London. The results suggest that there is much to be gained by incorporating search studies into housing market analysis and that there is significant potential for future work in this area

    Aim: In this study, it was aimed to evaluate the excessive daytime sleepiness, anxiety and depression symptomatology in normal-weight, overweight and obese individuals. Methods: In the study, 605 people who applied to the family medicine outpatient clinic between 2020 November 25 and 2021 March 5 were included. The questionnaire form evaluating the sociodemographic characteristics of the participants, the Hospital Anxiety and Depression Scale and the Epworth Sleepiness Scale were administered using a face-to-face interview technique. Results: Overweight status in primary school, high school/adolescence, and university/twenties were higher in obese than in overweight. Additionally, it was higher in overweight than in normal weight. The risk of being overweight was 2.19 times higher and the risk of being obese was 6.07 times higher than those with obesity in their family compared to those who did not. Excessive daytime sleepiness was 2.95 times higher in obese than in normal weight. Anxiety symptoms were 1.97 times higher in obese than in normal weight. Depression symptoms were 2.77 times more in overweight and 2.99 times more in obese compared to normal-weight individuals. Conclusion: As a result of this study, it was revealed that excessive daytime sleepiness, anxiety and depression symptomatologies are more common in obese compared to normal weight

    Investigation of the Apoptotic Effects of <em>Pistacia vera</em> Nut Skin Methanol Extract on Human Gastric Cancer Cell Line HGC-27

    Gastric cancer (GC) is one of the most prevalent malignant types in the world and an aggressive disease with a poor 5-year survival. GC is the third greatest global cause of cancer-related deaths. It is well recognized that tumor heterogeneity, a fundamental feature of malignancy, plays an essential role in the cancer development and chemoresistance. In this study, we investigated the apoptotic effects of Pistacia vera nut skin methanol extract on human gastric cancer cell line HGC-27. The results of this study demonstrate for the first time the protective effect of Pistacia vera nut skin methanol extract on gastric carcinoma

    Background and objective: We compared the efficacy of intravenous (iv) paracetamol versus dipyrone via patient-controlled analgesia (PCA) for postoperative pain relief in children. Methods: The study was composed of 120 children who had undergone elective tonsillectomy after receiving general anesthesia. Patients were divided into 3 groups according to the dosage of postoperative intravenous-patient-controlled analgesia: paracetamol, dipyrone, or placebo. Pain was evaluated using a 0- to 100-mm visual analog scale and 1- to 4-pain relief score at 30 min, 1, 2, 4, 6, 12, and 24h postoperatively. Pethidine (0.25 mg kg 1) was administered intravenously to patients requiring rescue analgesia. Pethidine requirements were recorded during the first 24h postoperatively, and treatment related adverse effects were noted. Results: Postoperative visual analog scale scores were significantly lower with paracetamol group compared with placebo group at 6h (p 0.05). Postoperative pethidine requirements were significantly lower with paracetamol and dipyrone groups compared with placebo group (62.5%, 68.4% vs 90%, p 0.05). Conclusions: Paracetamol and dipyrone have well tolerability profile and effective analgesic properties when administered iv-PCA for postoperative analgesia in children after tonsillectomy.

    WOS: 000321086300017The aims of this study were to investigate the association of ovarian I/R injury with oxidant/antioxidant and cyclooxygenase activity and to examine the effect of nimesulide in I/R injury. Rats were divided into four groups: sham group, ischemia-reperfusion group (IR), nimesulide 25 mg/kg group (NIM 25), and nimesulide 50 mg/kg group (NIM 50). The severe oxidative stress and inflammation that occurred in the ovarian tissue treated I/R were recovered by treatment of nimesulide. The histopathological findings, severe haemorrhage, oedema, vascular congestion accompanied with migration and adhesion of polimorphonuclear leukocytes in the endothelium were observed in the IR group that MDA, MPO and COX-2 levels were found high whereas GSH and COX-1 levels were found low. The severe histopathological findings in IR group were moderate in NIM-25 group whereas those were slight in NIM-50 group. This finding suggests that nimesulide prevents injury due to reperfusion following ischemia better when used with dosage 50 mg/kg
