Objective: In patients with spontaneous intracerebral hematoma (ICH), early-stage hematoma expansion has been associated with poor prognosis in literature. This study aimed to develop predictive parameter(s) as well as a new scale to define hematoma expansion and short-term prognosis in patients with ICH. Methods: In 46 patients with ICH, Glasgow Coma Scale (GCS) scores, non-contrast CT (NCCT) markers (hematoma volume on admission and follow-up, hypodensity, intraventricular hemorrhage, blend and island sign, BAT score), and modified Rankin Scale scores were evaluated for predicting the hematoma expansion risk and mortality risk. Furthermore, a newly developed scale called the ‘HEMRICH scale’ was constituted using the GCS score, hematoma volumes, and some NCCT markers. Results: Roc-Curve and Logistic Regression test results revealed that GCS score, initial hematoma volume value, hypodensity, intraventricular haemorrhage, BAT score, and HEMRICH scale score could be the best markers in predicting hematoma expansion risk whereas GCS score, intraventricular haemorrhage, BAT score, hematoma expansion, and HEMRICH scale score could be the best markers in predicting mortality risk (p = 0.01). Moreover, Factor analysis and Reliability test results showed that HEMRICH scale score could predict both hematoma expansion and mortality risks validly (Kaiser-Meyer-Olkin test value = 0.729) and reliably (Cronbach’s alpha = 0.564). Conclusion: It was concluded that the GCS score, intraventricular haemorrhage, and BAT score could predict both hematoma expansion risk and mortality risk in the early stage in patients with ICH. Furthermore, it was suggested that the newly produced HEMRICH scale could be a valid and reliable scale for predicting both hematoma expansion and mortality risk. © 2021 Informa UK Limited, trading as Taylor & Francis Group.

Background/purpose: MS and LB, the primary bacteria groups responsible for dental caries, and high levels of these bacteria in the mother promote transmission from mother to infant. The aim of this study was prevention of maternal MS and LB transmission on infants by using different preventive strategies and inhibition of early childhood caries proggession. Materials and methods: This study was conducted with 50 mother-child pairs who were randomly allocated into either a study group or a control group (n = 25 each). Mothers in the study group were enrolled in a detailed preventive program that included elimination of dental caries with restorative and antibacterial procedures, whereas those in the control group received only a single episode of oral-health education. Results: After 18 months, significant MS and LB inhibition was observed in the study group (p < 0.0001). In addition, caries prevalence in the infants in the study and control groups was 0% and 20% respectively, and the difference between the two groups was statistically significant (p = 0.020). Conclusion: These results indicate that primary preventive intervention and oral-health instruction can significantly inhibit the MS and LB levels of mothers and prevent caries in their children during the early years of life. © 2020 Association for Dental Sciences of the Republic of China 2013/02 This study was financially supported by the Scientific Research Project of Kirikkale University , Turkey (project number: 2013/02 ).

ALAKAS, Haci Mehmet/0000-0002-9874-7588 WOS:000599463700004 Enterprises have started to establish partnerships both to use their internal resources efficiently and to increase their environmental performance. Partnerships and interoperability of enterprises with different processes enable them to benefit more from their benefits. Moving towards the local and regional economy, these partnerships that increase environmental and own resources have created industrial symbiosis practices. Industrial ecology fields are established in these applications. Both environmental and economic gains can be achieved through the efficient use of resources by enterprises and the minimization of wastes. For the sustainability of these partnerships to be established by enterprises, they need to analyze the measures they take internally. In this study, the concept of industrial symbiosis and the criteria that are effective for the sustainability of these industrial symbiosis are evaluated. Analytical network process method is used. Thus, the industrial symbiosis infrastructures to be established by enterprises have been enabled to move strategically.

WOS:000588093700428 PubMed: 32898537 Herein, thermo- and pH-sensitive pectin-graft-poly(dimethylaminoethyl methacrylate) copolymer-coated magnetic nanoparticles were synthesized via a green and rapid synthetic approach based on microwave irradiation. Firstly, a novel thermo- and pH-sensitive pectin-graft-poly(dimethylaminoethyl methacrylate) copolymer (Pec-g-PolyDMAEMA) was synthesized and then, Pec-g-PolyDMAEMA based magnetic nanoparticles (Pec-g-PolyDMAEMA@Fe3O4) were produced via microwave-assisted co-precipitation method. The thermo/pH/magnetic field multi-sensitive hybrid nanoparticle was characterized by techniques like TEM, VSM, FT-IR, and TGA/DSC. In vitro release studies of 5-Fluorouracil (FL) were carried out by altering the temperature (37 and 44 degrees C), pH (5.5 and 7.4) and presence of an AMF. The FL release of Pec-g-PolyDMAEMA@Fe3O4@FL exhibited pH-sensitive behavior. They showed thermo/pH-sensitive FL release features with the greatest release of FL at 37 degrees C (56%) than at 44 degrees C (40%) and at pH of 7.4 (63%) than at pH of 5.5 (45%) within 48 h. The FL release was also significantly increased (100%) with the presence of a 50 mT magnetic field. These results indicate that the developed Pec-g-PolyDMAEMA@Fe3O4 nanoparticles are promising in the application of multi-stimuli-sensitive delivery of drugs. (C) 2020 Elsevier B.V.

Objectives Obesity has become an important public health problem because of its increasing prevalence and relation with many diseases and mortality. Studies have shown its association with oxidative stress. In this study, the effect of obesity on total amount of thiol and some glutathione S-transferase (GST) isozymes were investigated which could serve as an important criteria in dose adjustment of some certain drugs in obese. Methods The gastric tissues removed by gastrectomy operation from 29 morbid obese female patients were analysed for thiol levels and activities of total GST, GSTT1-1 and GSTM1-1. Patients were grouped according to age, presence of hypertension and/or diabetes, and family history. Results The average total thiol was 131.22 (±7.74) nmol/mg protein with no significant differences in between the groups. GSTT1 specific activities were about 20% higher in four groups: with ages over 35 years old, with hypertension, without diabetes and finally without family history, with respect to other groups. The differences between total GST and GSTM1 activity levels of experimental groups were not significant. Conclusions This is the first study to compare activities of GST isozymes and total thiol content in the stomach tissues of obese female patients accompanying some common metabolic disorders, age and family history.

WOS:000591824600001 The purpose of this study is to develop a control system that optimizes the phase plan, sequence and signal timing using the flower pollination algorithm (FPA). At the same time, it is aimed to improve the fixed-time control system with the optimum cycle length search approach based on the differential evolution algorithm. The applicability and performances of these two control systems were examined in 15 different traffic situations according to 4 different intersection geometries. Fixed-time and optimized fuzzy logic traffic controller (FLC) developed by Dogan were used as the reference control systems in performance comparison. The optimum cycle length search system can achieve approximately 18% improvement over the fixed-time system, but showed lower performance than the FPA and FLC control systems. The FPA system has proven its applicability by achieving the best performance with about a 30% improvement compared to the fixed-time system and about 3% improvement compared to the FLC system. The FPA approach, which has a fast and effective performance, has been found to be an alternative method for intersection control, and it is foreseen that it can increase the intersection capacity and reduce the negative effects such as delay and fuel consumption.

GUN GOK, Zehra/0000-0001-6426-0395 WOS:000590515900001 Because of having high mechanical properties and cheapness of PET textiles, functionalization of them for new properties is an active research area. In the present work, methacrylic acid (MAA)-grafted PET fibers (PET-g-MAA) were obtained by grafting of MAA monomers to PET surface for an antimicrobial material synthesis. The morphologies of the obtained graft copolymers were examined with a scanning electron microscopy (SEM), and the chemical modification after grafting was determined with Fourier-transform infrared spectroscopy (FTIR) analysis. Subsequently, silver ions were adsorbed onto the PET-g-MAA fibers surface and the adsorbed ions to the surface were reduced to silver nanoparticles (AgNPs) by UVC light. The morphology of fiber surfaces modified with MAA and coated with AgNPs was examined by SEM studies, and it was observed that AgNPs were disturbed along the fibers. The presence of silver on the surface was also confirmed by energy-dispersive X-ray spectroscopy (EDS) and energy dispersion X-ray fluorescence spectrometry (EDXRF). The crystalline structure of the original PET fiber, PET-g-MAA fiber and PET-g-MAA fiber modified with AgNPs was investigated by X-ray diffraction (XRD). The thermal properties of the obtained fibers were investigated by thermogravimetric analysis (TGA). The immobilization of AgNPs on the grafted fibers leads to a change on the patterns of TGA curves. The most significant change is the less weight reduction in the temperature range of 200-300 degrees C. Disk diffusion test was performed using Staphylococcus aureus (ATCC 6538) and Escherichia coli (ATCC 25,922) bacteria in order to investigate the antibacterial ability of the obtained fibers, and it was found that the fibers coated with AgNPs had antibacterial effect on both bacterial species. The cytotoxicity of the groups with the best antibacterial properties was determined by MTT test, and the synthesized material did not have cytotoxic effects on L929 fibroblast cells. The material obtained has the potential to be used in antimicrobial applications. Krkkale University The project was financially supported by Krkkale University with the project number 2019/010.

Temocin, Zulfikar/0000-0001-7151-9772 WOS:000589568900001 The integration of the enzymes on the solid electrode surfaces is an indispensable step for the construction of the bioelectrochemical electrode. In the current work, the blend nanofibers consisting of poly (vinyl alcohol) and poly(ethyleneimine) were deposited by the electrospinning method on an H2O2-sensitive modified glassy carbon electrode. Glucose oxidase was immobilized on the glutaraldehyde-activated blend nanofibers. Bioelectrochemical electrode displayed a good linear response to the glucose concentration ranges with two separate calibration curves, from 2 to 8 mmol L-1 and from 10 to 30 mmol L-1. Besides, it showed a high anti-interference performance against ascorbic and uric acids as well as long-term storage stability over 63 days. Moreover, analysis results in a diluted human serum sample showed that the prepared bioelectrochemical electrode has the ability to measure glucose in real samples.

WOS:000588848000001 Helping students at all grade levels to develop inquiry skills has been an ambitious goal that science educators have been pursuing for the last three decades. Yet, studies consistently report cases of failure from science classrooms with regard to inquiry-based teaching. The purpose of this study was to develop an instrument for measuring primary teachers' self-efficacy to teach science through inquiry. An expert panel methodology was used to develop and validate the initial instrument. The final, and thus administered survey consisted of 29 Likert-scale questions. To further validate and develop the instrument, we collected data from 358 pre-service primary teachers enrolled in teacher education programs at five different universities in Turkey. According to exploratory factor analysis, there is only one interpretable factor. Cronbach's alpha internal consistency coefficient was found to be 0.97 for the reliability, indicating the robust scale reliability. We present the need for such an instrument and evidence on the validity and reliability of the instrument. We further discuss the potential contributions of this instrument to the field.

Ulgen, Asaf Tolga/0000-0002-7112-5607 WOS:000587111900001 This work is interested in the critical changes in the load-independent microhardness performance parameters with the partial substitution of Sr2+ inclusions for the Ti4+ impurities in the Bi-2212 inorganic solids with the help of the theoretical approximations as regards Meyer's law (ML), proportional sample resistance (PSR), modified proportional sample resistance (MPSR), elastic/plastic deformation (EPD), Hays-Kendall (HK) and indentation-induced cracking (IIC) models found on the experimental microhardness tests applied to a variety of test loads between 0.245 and 2.940 N for the first time. Moreover, Ti-substituted Bi-2212 bulk ceramics (Bi2.1Sr2.0-xTixCa1.1Cu2.0Oy) are prepared within mole-to-mole ratios of x = 0.000, 0.010, 0.030, 0.050, 0.070, 0.100 by the standard solid-state reaction method in the atmospheric pressure conditions. It is provided that Ti partial substitution in the superconducting system descends unsmilingly the mechanical durability, stability, strength, toughness, critical stress, stiffness and flexural strengths of Bi-2212 superconducting solids studied owing to the increment of crystal structural problems. Moreover, it is obtained that the degradation in the crystal structural leads to diminish the typical ISE characteristic of Bi-2212 superconducting ceramic compounds. At the same time, the results show that all the models (especially IIC approach) can serve as the suitable descriptors for the determination of the variation in the load-independent mechanical performances of the Bi-2212 superconducting materials.

Hamamci, Mehmet/0000-0001-7100-3952 WOS:000584996300001 Purpose The aim of this study was to investigate the sleep quality of spouses of patients with restless legs syndrome (RLS). Methods Total 49 spouses of patients with RLS (Group 1) and 47 age- and sex-matched healthy volunteers (Group 2) were enrolled. Sleep quality was assessed by Pittsburgh Sleep Quality Index (PSQI). Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) were applied to all participants. High risk of the sleep apnea was excluded by Berlin Questionnaire. The RLS severity of patients was determined by International Restless Legs Syndrome rating scale. Results The mean age was 44.91 +/- 12.81 in Group 1 (25 female, 24 male) and 41.48 +/- 8.20 in Group 2 (25 female, 22 male). 35 (71.4%) participants in Group 1 and 20 (42.6%) participants in Group 2 had poor sleep quality (p = 0.004). Sleep quality was poor in 84% (n = 21) of female and 58.3% (n = 14) of male in Group 1 (p = 0.05). Sleep quality, insomnia and daytime sleepiness found to be correlated significantly with RLS severity (p < 0.05). Scores of BDI and BAI also correlated with PSQI (p = 0.002, p = 0.03). The significant relationship was observed between subjective sleep quality, sleep latency, and disease severity (p = 0.03, p = 0.005). Conclusion Restless legs syndrome may be a factor that may impair the quality of sleep in spouses of patients. Sleep quality is important in an individual's relationship with his / her health and spouse. In the treatment and follow-up of patients with RLS, their spouses should also be evaluated in this respect.

WOS:000597061800006 PubMed: 33257608 Objective: This study is an investigation of the relationship between erectile dysfunction and epicardial adipose tissue and carotid intima-media thickness, which are indicators of endothelial dysfunction and subclinical atherosclerosis, in patients with newly diagnosed hypertension. Methods: The epicardial adipose tissue and carotid intima-media thickness of 101 male patients with newly diagnosed hypertension were measured using echocardiography between May 1, 2018 and May 31, 2019. Evaluation of erectile dysfunction was performed using the 5-item version of the International Index of Erectile Function (IIEF-5) in a face-toface interview in the urology outpatient clinic. The data of patients with and without erectile dysfunction were compared. Results: There was a significant relationship between the presence and severity of erectile dysfunction and epicardial fat tissue and carotid intima-media thickness in patients with newly diagnosed hypertension. Left ventricular diastolic function was found to be more impaired in patients with erectile dysfunction. Conclusion: Erectile dysfunction was determined to be related to increased epicardial fat tissue and carotid intima-media thicknesses in patients with newly-diagnosed hypertension.

WOS:000575131100001 Objectives The aim of this study was to investigate the role of CD68 (+) histiocytic macrophages (H-M) in the nasal polyp pathogenesis. Materials and Methods The study group consisted of 24 adult patients with nasal polyposis. The control group consisted of 11 adult patients without nasal polyps. A total of 36 nasal polyp samples (10-nasal cavity, 10-maxillary sinus, and 16-ethmoid sinus) from the study group and 11 inferior turbinate samples from the control group were analyzed by immunohistochemical staining, with monoclonal antibodies against CD68 (+) H-M. Results CD68 positivity was significantly higher than the control group in the subepithelial (SE) layer of the ethmoid sinus, and deep layers of nasal cavity, maxillary, and ethmoid sinuses. In SE and deep layers of ethmoid and maxillary sinuses, CD68 positivity was significantly higher than that of the epithelial layer. In the deep layer, histiocytic macrophages tended to gather around eosinophils. Conclusion The high numbers of CD68 (+) histiocytic macrophages mainly located in deep layer of lamina propria may be responsible for the phagocytosis of eosinophils within the polyp tissue. Therefore, it may be concluded that increased macrophages in nasal polyps do not trigger the growth of nasal polyps. Instead, they may serve to reduce the number of eosinophils in already-developed nasal polyps.

Tureci, RG/0000-0001-6309-6300 WOS:000575238200001 We study numerical solution of Singular Integral Equations (SIE) of particle transport theory. We convert them into matrix equations by standard discretization process. It is found that the matrices are highly ill-conditioned and can be solved by Singular Value Decomposition (SVD) method. One expects that matrices resulting from expansions over Partial Range will not be ill-conditioned. We find this is not true though their ill-conditioning is an order of magnitude less than those of full or half range. Reasons for this phenomenon are explained.

Dikmen, Fatih/0000-0001-8251-5881 WOS:000570613800001 Premise of research. Previous pollination ecology studies ofSalviahave shown that there is low specialization for certain subgroups of bees and that pollinator number varies with species and locality. We studied 12Salviaspecies (three clades with different corolla morphologies and staminal lever mechanisms) that in part co-occur and coflower to examine prezygotic isolation mechanisms and the degree of specialization versus generalization in pollination ecology. Methodology. Pollinators were identified using field observations, photos, and related literature across three sites in Turkey. Video documentation of the visitation rate and the site of pollen placement on the pollinator body, morphometric measurements between flowers and pollinators, flowering time, flower color, handling time, and stigma contact ratio were analyzed. Plant-pollinator networks were constructed. Pivotal results. Mechanical, phenological, and ethological isolation occurs among sympatricSalviaspecies. A morphological fit is evident between flower tube length and the proboscis length of the main pollinators. Pollinator networks indicate that most species are ecological generalists and that only a few are specialists. Conclusions. The 12Salviaspecies, though phenotypically and functionally specialized by their zygomorphic, bilabiate flowers and bee-pollination syndrome, differ in the degree of their ecological specialization. Most of the sympatricSalviaspecies tend to be ecologically generalized, with two or more main pollinators and a few additional secondary pollinators, while a fewSalviaspecies are clearly specialized. Some floral traits (e.g., flower color, morphology, size, corolla tube length and width of the corolla tube entrance, type and size of the staminal lever mechanism, small numbers of flowers in the inflorescence), a short flowering time, and a small population size appear to be correlated with the degree of ecological specialization.

Unexpected stops or entry/exit manoeuvres of vehicles on the road may cause the related lane to become blocked. When this blocking happens in a signalised intersection zone, it also affects intersection performance. Determining the extent of this effect will assist traffic engineers with intersection design and performance analysis. In this study, the effects of Lane Blockage (LB) on intersection performance under various traffic conditions were analysed according to two performance criteria. ANN (Artificial Neural Network) models were also developed to enable the prediction of intersection performance. As a result of the analysis, it was clearly determined that the effect of LB on intersection performance was limited at v/c 0.95 and will therefore be useful in LB-related intersection performance analysis.

GULNAR, EMEL/0000-0002-4766-8927 WOS: 000529396900001 PubMed: 32326833 This study was conducted to determine the effect of the storytelling technique on the attitudes of nursing students toward death as a mixed research design. The study sample consisted of 94 senior students attending the nursing department of a university in Turkey. Quantitative data were collected by using the introductory characteristics form and the Death Attitude Profile-Revised, while qualitative data were collected through focus group interviews with the semistructured interview form. The data were analyzed according to number, percentage, Wilcoxon test, paired samples ttest, and descriptive analysis method. The mean Death Attitude Profile-Revised Scale score of the students before receiving the relevant education was 4.17 +/- 0.21. This score increased to 4.25 +/- 0.24 after the students received the education and the difference was found to be statistically significant (p < .05). In the qualitative section of the study, the data obtained from the attitudes of the students toward death were coded, and four themes were determined. The qualitative data obtained from the focus group interviews with the participating students were presented under four themes: the contribution of the storytelling technique to learning, the effect of the storytelling technique on the attitude toward death, thoughts about the storytelling technique, and contribution of the course to knowledge, skills and attitude in giving care to the dying patient. As a result of the study, explaining the subject of death with the storytelling technique was determined to positively affect the attitudes of the students toward death.

Demirci, Cevher Savcun (Balikesir Author), BACKGROUND/AIMS This study aimed to determine exercise barriers in older individuals and to examine their relationship with physical activity, sleep, and fatigue. MATERIAL and METHODS A total of 100 older individuals aged more than 65 years who were staying in a private nursing home and elderly care center were involved in this study. The sociodemographic information of the individuals and the used scales were recorded through face-to-face interviews held by a physiotherapist. Their exercise barriers, physical activity levels, sleep conditions, and fatigue were evaluated by the Exercise Benefits/Barriers Scale, Physical Activity Scale for the Elderly (PASE), Pittsburgh Sleep Quality Index (PSQI), and Fatigue Severity Scale. RESULTS The mean age of older individuals was 71.32 +/- 6.33 years. There were significant positive and low relationships between exercise barriers in older individuals and the PSQI's sleep quality and day dysfunction owing to sleepiness (DAYDYS) subparameters, the PSQI total score and fatigue. Furthermore, significant negative and low relationships were found between the PASE(Leisure activity) and sleep duration, sleep quality, PSQI(MEDS), PSQI(Total), and fatigue severity, between the PASE(Home activity) and PSQI(Total) score, and between the PASE(Work activity) and sleep duration, sleep latency, and fatigue. CONCLUSION The study results suggest that conditions such as sleep quality and fatigue can be considered an exercise barrier. Regular exercise training planned for older individuals individually or as a group will improve sleep quality and provide improvement in their fatigue level. It is crucial to plan and implement in particular personal exercise and physical activity programs and lifestyle modifications, physiotherapy rehabilitation, and energy conservation techniques for sleep quality to maintain and improve the health of older individuals.

The objective of this study was to evaluate physical and mechanical properties of experimental panels manufactured from eastern red cedar (Juniperus virginiana L.) using modified starch as binder. Modulus of elasticity (MOE), modulus of rupture (MOR), internal bond strength (IB), hardness and dimensional stability in the form of thickness swelling and water absorption in addition to surface quality of the samples were tested. Panels were manufactured at three density levels, which are 0.60 g/cm3, 0.70 g/cm3 and 0.80 g/cm3. The highest MOE, MOR and IB values for the samples having 0.80 g/cm3 density were determined as 2207.16 MPa, 15.17 MPa and 0.87 MPa, respectively. Thickness swelling values of the samples soaked in water for 2 h ranged from 15.38 % to 23.23 %. Micrographs taken on the samples using scanning electron microscope revealed that starch was uniformly distributed within the particles. Based on the findings in this study, it appears that eastern red cedar would have a potential as a raw material to manufacture particleboard panel using modifi ed starch as green adhesive with accepted physical and mechanical properties., Cilj istraživanja bio je odrediti fizička i mehanička svojstva eksperimentalnih ploča proizvedenih od drva crvenog cedra (Juniperus virginiana L.) uz upotrebu modificiranog škroba kao veziva. U eksperimentu su na osnovi debljinskog bubrenja i upijanja vode ispitivani modul elastičnosti (MOE), modul loma (MOR), međuslojna čvrstoća (IB), tvrdoća i dimenzijska stabilnost, kao i kvaliteta površine uzoraka. Ploče su proizvedene u tri gustoće: 0,6; 0,7 i 0,8 g/cm3. Najveće vrijednosti MOE, MOR i IB za uzorke gustoće 0,8 g/cm3 bili su redom: 2207,16 MPa; 15,7 MPa i 0,87 MPa. Vrijednosti debljinskog bubrenja uzoraka potapanih u vodi tijekom dva sata kretale su se u rasponu od 15,38 do 23,23 %. Mikrografi je snimljene na uzorcima elektronskim pretražnim mikroskopom otkrile su da je škrob ravnomjerno raspoređen unutar iverja. Na temelju rezultata ovoga istraživanja, čini se da bi drvo crvenog cedra moglo biti potencijalna sirovina za proizvodnju iverica, uz uporabu modificiranog škroba kao ekološki prihvatljivog ljepila poželjnih fizičkih i mehaničkih svojstava.

The title compound crystallizes with a single mol­ecule in the asymmetric unit. The phenol ring makes a dihedral angle of 36.56 (3)° with the nitro­benzene ring. In the crystal, mol­ecules are linked by C—H⋯O inter­actions, forming chains along the b-axis direction., The title compound, C15H14N2O3, was prepared by condensation of 2-hy­droxy-5-methyl-benzaldehyde and 2-methyl-3-nitro-phenyl­amine in ethanol. The configuration of the C=N bond is E. An intra­molecular O—H⋯N hydrogen bond is present, forming an S(6) ring motif and inducing the phenol ring and the Schiff base to be nearly coplanar [C—C—N—C torsion angle of 178.53 (13)°]. In the crystal, mol­ecules are linked by C—H⋯O inter­actions, forming chains along the b-axis direction. The Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H⋯H (37.2%), C⋯H (30.7%) and O⋯H (24.9%) inter­actions. The gas phase density functional theory (DFT) optimized structure at the B3LYP/ 6–311 G(d,p) level is compared to the experimentally determined mol­ecular structure in the solid state. The HOMO–LUMO behaviour was elucidated to determine the energy gap.

WOS:000583802900045 Zeolite was investigated as a potential component in the production of medium-density fiberboard (MDF). A mixture of beech (40%), oak (30%), and pine (30%) wood chips was used for fiber production. Chips were cooked for 4 min in an Asplund defibrator with a vapor pressure of 8 bar, and a temperature of 180 degrees C. Chemicals were added on fibers in the blow line. The resins were added at 11 wt% based on oven-dried wood fibers. Ammonium sulphate was added at 0.72 wt% based on resins. Paraffin wax was added as 1.8 wt% based on resin. Zeolite was prepared in a separate tank for its use instead of lignocellulosic fibers in the production of 1 m(3) MDF. The fibers were dried to 12% moisture. A temperature of approximately 190 degrees C and a pressure of approximately 32 kg.m(-2) were applied to the mixture for 280 s to make MDF panels (500 x 490 x 14 mm). Mechanical properties of MDF boards were significantly increased for bending (MOE) and elastic modulus (MOR), but a little negatively affected on internal bond (16), physical properties were negatively increased thickness swelling (ThS) and water absorption (WA). Consequently, increasing zeolite minerals in MDF boards showed best results of formaldehyde emission properties of MDF.

WOS:000565809700014 PubMed: 32994776 Introduction: Eyelid tumours mostly originated from skin and its appendeges. External carcinogens like UV radiation causes cell damages in the eyelid skin and contributes to carcinogenesis. Apoptosis is a very important mechanism to prevent these damage and probable neoplatic change. Aim: To compare caspase-3, p53 and Bcl-2 levels between patients with basal cell carcinoma (BCC) of the eyelid and healthy individuals. Material and methods: Pathology archives from October 2012 to April 2015 were scanned for BCC biopsies of the eyelid and tissue removed during blepharoplasty and entropion procedures. A total of 36 specimens were found. The specimens were divided into two groups: BCC group and controls (consisting of eyelid tissue removed during routine blepharoplasty). The pathology specimens were then stained using p53, Bcl-2 and caspase-3 stains and the intensity of staining was graded on a 0-3 scale. Results: Samples from a total of 36 patients were included in the study. Eighteen (50.0%) patients were female. There were 13 patients in the BCC group and 23 patients in the control group. The mean age was 66.0 +/- 10.8 years in the BCC group, and 65.61 +/- 11.22 years in the control group. The caspase-3 staining was lower in the BCC group than in the control group. No significant differences were found between the BCC group and the control group in terms of p53 levels or Bcl-2 levels (both of them, p = 1.000). Conclusions: The caspase-3 level was lower in the BCC group. This result suggests that these enzymes can play a significant role in carcinogenesis of eyelid BCC.

PubMed: 32416307 In present work, temperature-responsive flurbiprofen (FLU) containing chitosan/hydroxypropyl cellulose (CS/HPC) blend nanospheres were prepared using emulsion method. The structures of blend nanospheres were characterized by ATR-FTIR, XRD, SEM, DSC/TGA, zeta potential and particle size analyses. Their lower critical solution temperatures (LCST) were determined and found to be 42 °C. In vitro release studies were performed in gastrointestinal-tract simulated conditions at 30 °C, 37 °C and 44 °C. As the medium temperature was increased, the release of FLU decreased, indicating that blend nanospheres had temperature-responsive feature. The FLU release demonstrated that release profiles depend upon CS/HPC ratio, amount of FLU present in the nanospheres and percentage of cross-linker used. Moreover, the cytotoxicity tests were performed via MTT method and it was observed CS/HPC nanospheres were biocompatible. Based on the in vitro release profile and cytotoxicity studies, the fabricated CS/HPC blend nanospheres could be a promising candidate as a temperature-responsive nano-carrier for controlled drug release. © 2020 Elsevier B.V. 2014/39 The authors are thankful to the Scientific Research Projects Coordination Unit of Kırıkkale University [Project number: 2014/39 ] for their financial support.

WOS:000563849800014 The objective of this research was to evaluate the strength of corner joints of box shaped furniture made from eastern red cedar (Juniperus virginiana L.) and corn starch binder southern sample. Various types of corner joint techniques were evaluated (glued, glued and screwed, and glued with dowel corners). Eastern redcedar particle samples with corn starch and glutaraldehyde were used. Overlaid and non-overlaid particleboards along with sandwich panels were used at "L" type corner joints. Tension and compression strength moment values were measured. Particleboard panel joint mounted with dowel resulted in the highest tension strength moment values followed by the specimens having a sandwich-type configuration combined with a dowel. Particleboard and overlaid sandwich-type panels glued with polyvinyl acetate (PVAc) had the lowest strength values. It appears that composite panels manufactured with modified starch have the potential to be used for corner joints.

Utar, Merve/0000-0002-5876-3743 WOS:000562984900001 PubMed: 32845029 This study intended to analyze microcracks and fractographic markings on the surface of all ceramic crowns after milling and compare the fracture loads. 90 crowns were manufactured from two feldspathic (Priticrown-Pr and Vita Mark II-Vi) and a lithium disilicate (EmaxCAD-Em) blocks (n= 30). Two groups (n= 15) were prepared for each ceramic. In the first group, crowns were analyzed twice via the fluorescent penetrant method for microcrack detection, after the manufacturing process and thermal cycles. The load to fracture test was applied at a crosshead speed of 0.5 mm/min until catastrophic failure. Second group crowns were directly cemented onto the Co-Cr dies following the manufacturing process and loaded to fracture. Fractographic markings were analyzed through scanning electron microscope. Spearman correlation analysis, Kruskal-WallisHtest, Mann-WhitneyUtest, and Wilcoxon Signed Rank test were applied (alpha= .05). Fracture loads of Em crowns were higher than other groups (p .05). Thermal cycling did not affect microcrack numbers and fracture loads (p > .05). Tooth-shaped multilayered Pr blocks did not provide an advantage in terms of microcrack and fracture loads.

WOS:000560855500001 This technical review article focuses on determining a robust and precise lower-level sulfur detection procedure. When measuring under 0.1 ppm and approaching zero values, the limits of the instrument are pushed to separate real signal response from noise. One of the performance parameters in method validation studies is to determine these near-zero value samples reliably when the instrument works near the noise signal level. The study examined the early stages of the method development process, regarding the determination of the validation parameters limit of blank, limit of detection (LOD), and limit of quantification (LOQ). The sulfur content in diesel fuel was determined with guidance from the standard ISO 20846:2011. The average sulfur readings of a diesel test sample and blank (99% iso-octane) were measured as 3.9 and 0.0196 ppm, respectively. For a 1.5% diluted diesel test sample the mean sulfur value was measured as 0.0613 ppm and this value was verified as the LOD. For a 3% diluted diesel test sample the mean sulfur value was measured as 0.1158 ppm and this result was verified as the LOQ. The LOD and LOQ were tested for conformity. The accuracy of these tested values was checked according to EUROCHEM guidelines.

WOS:000560981900001 PubMed: 32813169 Purpose The aim of this retrospective study was to investigate the soft tissue changes after maxillary advancement in class III patients. Methods Pre- and post-operative lateral cephalometric radiographs of 20 patients treated with maxillary advancement surgery were included in our study. Skeletal, dental and soft tissue measurements were performed by a single researcher using Dolphin Imaging software version 11.95 (Dolphin Imaging, Chatsworth, CA, USA). Pairedttest was used for statistical evaluation andp < 0.05 was considered statistically significant. Results The amount of motion in soft tissues, respectively, are UL-E: 2.05 mm, ST.A: 0.65 mm, ST.B: - 5 mm, ST.Pog: - 5.73 mm, ST.Conv: - 3.95 mm, nasal prominence: - 1.58 mm, nasal height: 2.76 mm and upper lip length: 2.22 mm. The change of distance to horizontal and vertical reference planes are, respectively, Prn-HRL: 3.02 mm Prn-VRL: 1.76 mm Sn-HRL: 2.76 mm Sn-VRL: 2.94 mm ST.A-HRL: 3.74 mm ST.A-VRL: 3.81 mm UL-HL: 3.93 mm UL-VRL: 4.57 mm LL-HRL: 2.29 mm LL-VRL: 5.31 mm. Conclusions It can be concluded that soft tissues related to maxilla moved anteriorly due to maxillary advancement.

WOS:000560988800009 This study aims at detecting antimicrobial resistance properties including extended spectrum beta-lactamase (ESBL), AmpC, carbapenemase activities (imipenem, meropenem and ertapenem), and colistin resistance of isolated and serotyped Salmonella spp. strains from various foods (mostly chicken and chicken products) that cause food poisoning. The ISO 6579-3 (Kaufmann-White scheme) method was used for serotyping of Salmonella spp. and for detection of antimicrobial resistance with Minimum Inhibitory Concentration (MIC) as reported by EURL-AR. Inoculums were separated into EUVSEC and EUVSEC2 panels using the Sensititre AIM Automated Inoculation Delivery System. The results were monitored in a semiautomatic vision reader and evaluated according to EUCAST Resistance to 14 different antibiotics of 34 serotyped Salmonella spp. strains were examined in the first panel in this study. Most of these strains were found to be resistant to ciprofloxacin, colistin, nalidixic acid, sulfonamides, tetracycline, tygecycline, and trimethoprim. Nine of these agents (26.4%) were determined as single-drug resistant and 20 of them (55.8%) were determined as multidrug-resistant. Only 2 strains were determined to be resistant to cefotaxime and ceftazidime; however, BBL activity was not observed in the second stage of the analysis, in which EUVSEC2 panels were used. All the strains for carbapenemase activities were determined as sensitive to imipenem, meropenem, and ertapenem. Also, all the strains for AmpC activities were found to be sensitive to cefoxitin. The same resistance properties of the isolates were detected against nalidixic acid, ciprofloxacin, and tetracycline. Colistin resistance was detected as 44.1%. Salmonella spp. strains isolated from foods that caused food poisoning were determined as multidrugresistant to antibiotics at a high rate. This study is the first one in Turkey that has evaluated ESBL, AmpC, carbapenemase activity, and colistin resistance of Salmonella spp., which was isolated from the food poisoning cases, by using MIC test (recommended by EURL-AR). In Turkey, antibiotics use should be avoided especially in chicken farms in order to prevent the increasing multidrug resistance of Salmonella spp.

Materials and methods A total of 50 patients were included in the study. Patients with a hump greater than 4 mm and mild septal deviation participated in the study. The patients were divided into two groups. Group 1 consisted of 26 patients who underwent Let Down rhinoplasty, while Group 2 consisted of 24 patients who underwent open rhinoplasty with spreader graft. NOSE, SNOT-22, and VAS scales were completed by both groups preoperatively and postoperatively. Results There was no significant difference between the groups in terms of age and gender. Postoperative values of scales were significantly lower than preoperative values in Group 1 (p < 0.001). In Group 2, postoperative values were significantly lower than preoperative values (p < 0.001). There was no significant difference between the two groups according to NOSE, SNOT-22 and VAS scores. Conclusion According to the comparison of scale scores, both Let Down rhinoplasty and open technique rhinoplasty using spreader graft improved nasal functional results such as nasal obstruction.

Bayram, Cem/0000-0001-8717-4668; Keceli, Huseyin Gencay/0000-0001-6695-2133 WOS:000557380800001 PubMed: 32776328 Objective To test the surface properties and in vitro effects of a new sequential release system on MC3T3-E1 cells for improved osseointegration. Background BMP6-loaded anodized titanium coated with PDGF containing silk fibroin (SF) may improve osseointegration. Methods Titanium surfaces were electrochemically anodized, and SF layer was covered via electrospinning. Five experimental groups (unanodized Ti (Ti), anodized Ti (AnTi), anodized + BMP6-loaded Ti (AnTi-BMP6), anodized + BMP6 loaded + silk fibroin-coated Ti (AnTi-BMP6-SF), and anodized + BMP6-loaded + silk fibroin with PDGF-coated Ti (AnTi-BMP6-PDGF-SF)) were tested. After SEM characterization, contact angle analysis, and FTIR analysis, the amount of released PDGF and BMP6 was detected using ELISA. Cell proliferation (XTT), mineralization, and gene expression (RUNX2andALPL) were also evaluated. Results After successful anodization and loading of PDGF and BMP6, contact angle measurements showed hydrophobicity for TiO(2)and hydrophilicity for protein-adsorbed surfaces. In FTIR, protein-containing surfaces exhibited amide-I, amide-II, and amide-III bands at 1600 cm(-1)-1700 cm(-1), 1520 cm(-1)-1540 cm(-1), and 1220 cm(-1)-1300 cm(-1)spectrum levels with a significant peak in BMP6- and/or SF-loaded groups at 1100 cm(-1). PDGF release and BMP6 release were delayed, and relatively slower release was detected in SF-coated surfaces. Higher MC3T3-E1 proliferation and mineralization and lower gene expression ofRUNX2andALPLwere detected in AnTi-BMP6-PDGF-SF toward day 28. Conclusion The new system revealed a high potential for an improved early osseointegration period by means of a better factor release curve and contribution to the osteoblastic cell proliferation, mineralization, and associated gene expression.

Introduction. The aim was to determine the validity and reliability of the Turkish version of the self-rated fall risk questionnaire (FRQ). Methods. The study included 100 individuals aged over 65 years. For test-retest reliability, firstly, the questionnaire was applied to volunteers, and, after 15–20 days, the individuals were asked to fill in the questionnaire again. For internal consistency, its correlation was evaluated with the Berg Balance Scale and Timed Up and Go test, of which Turkish reliability and validity studies had been previously performed in older individuals. Results. The internal consistency of FRQ results obtained in the first (test results) and second (retest results) tests was found to be moderate (Cronbach’s alpha coefficient: 0.771 and 0.854, respectively). The test-retest reliability of the FRQ total score and the total score of the other scales was excellent and turned out to be statistically significant. in the statistical analysis, correlations were observed between both the test results and the retest results (p < 0.05). Conclusions. in this study, the Turkish version of FRQ, which provides essential data for evaluating fall risk in older individuals and for consulting a specialist for detailed examination if necessary, was found to be highly valid and reliable. © University School of Physical Education in Wroc?aw The authors would like to thank all individuals who contributed to the completion of this work, especially the study participants.

Turkyilmaz, Ali/0000-0003-0641-0062 WOS:000553969300001 PubMed: 32735400 This in vitro study aimed to investigate the tubular penetration depth of four different sealers used with two different obturation methods in the apical, middle, and coronal root canal dentin. Eighty-four single-rooted teeth were instrumented until the F4 ProTaper universal rotary file and filled with AH26, AH Plus (Dentsply, DeTrey, Konstanz, Germany), RealSeal (SybronEndo, Orange, CA), and MTA Fillapex (Angelus, Londrina, Brazil) using cold lateral condensation (CLC) and single-cone (SC) obturation techniques. Thereafter, the roots were sectioned longitudinal and prepared for scanning electron microscope evaluation. The maximum and minimum sealers penetration depth into dentinal tubules at the apical, middle, and coronal regions and the average depth of sealer penetration were calculated. The data was statistically analyzed two-way ANOVA and post hoc Tukey and Dunnett tests and independent samplesttest using maximum mean values. There was no statistically difference between the obturation methods (p> .05). When the sealers are evaluated within themselves AH26 was affected by obturation methods significantly (p< .05). Also the results revealed a significant difference between root regions (p< .05). AH26 and RealSeal root canal sealers had the highest penetration values with CLC and SC obturation techniques, respectively. The obturation method did not affect the penetration amount of root canal sealers. RealSeal root canal sealer performed better penetration ability than the other sealers. Apical third of the root in all groups showed lowest penetration depth.

Bozaci, Ibrahim/0000-0002-9584-6126 WOS:000548482500048 The study seeks to understand the effects of boredom proneness on impulse purchasing and smartphone addiction of young consumers. Moreover, the possible mediating role of smartphone addiction is tested for the effect of boredom proneness on impulse purchasing. Nowadays, the effect of emotions on human behavior is generally accepted, and boredom is one of the important and common problematic feelings or moods at various levels of life due to factors like unemployment, not being able to work in a suitable job, not getting appropriate education matching individual abilities, monotony of tasks, and feeling life is meaningless. Investigating the effect of boredom on specific consumer behavior would increase our knowledge about consumer behavior. For the research, a survey was conducted 313 students from Kirikkale University, Keskin Vocational High School; the data were collected by convenience sampling method. The data were processed through statistical tools like exploratory factor analysis, coefficient alphas, and regression analysis. The results of the study reveal that boredom proneness affects impulse purchasing and smartphone addiction. In addition, it is understood that smartphone addiction plays a mediating role in the effect of boredom proneness on impulse purchasing. These results indicate that boredom can be an important factor affecting certain negative consumer behaviors.

AYDIN, TUNA/0000-0001-6808-9425; Casin, Eray/0000-0003-3698-2248 WOS:000552932700001 Raw materials and energy are among the most important costs in ceramic sanitaryware production. With the decrease in raw material sources and increasing costs of energy in recent years, researches on alternative raw materials and energy have started to gain importance. In this study, blast furnace slag and spodumene were used to reduce both energy and raw material costs. In standard vitreous china ceramic sanitaryware, a maximum of 15% blast furnace slag and 4% spodumene was used instead of sodium feldspar. In this study, the effects of CaO, MgO, and Li2O on microstructure, technological properties such as flexure strength, water absorption, porosity, bulk density; and also, thermal properties such as sintering analysis were investigated by using a non-contact optical dilatometer and thermal expansion. The dry strength and flexure strength of fired samples increased. The increase in dry strength was approximately 47%. The increase in flexure strength was approximately 67%. The reduction in the thermal expansion coefficient values was approximately 17%, which is also important in terms of stability of the final product. As a result, the use of blast furnace slag and spodumene will result in a reduction in both energy and raw material costs. The spodumene and BFS provided a reduction in sintering temperature at a rate of approximately 60 degrees C. The flue gas emissions may also reduce because flue gas emissions are higher as the temperature inside the furnace is higher. The spodumene and blast furnace slag addition provide a decrease in the peak of sintering temperatures so that flue gas emissions will reduce. [GRAPHICS] .

Bakour, Khaled/0000-0003-3327-2822 WOS:000550612900003 In this paper, VisDroid, a novel generic image-based classification method has been suggested and developed for classifying the Android malware samples into its families. To this end, five grayscale image datasets each of which contains 4850 samples have been constructed based on different files from the contents of the Android malware samples sources. Two types of image-based features have been extracted and used to train six machine learning classifiers including Random Forest, K-nearest neighbour, Decision trees, Bagging, AdaBoost and Gradient Boost classifiers. The first type of the extracted features is local features including Scale-Invariant Feature Transform, Speeded Up Robust Features, Oriented FAST and Rotated BRIEF (ORB) and KAZE features. The second type of the extracted features is global features including Colour Histogram, Hu Moments and Haralick Texture. Furthermore, a hybridized ensemble voting classifier has been proposed to test the efficiency of using a number of machine learning classifiers trained using local and global features as voters to make a decision in an ensemble voting classifier. Moreover, two well-known deep learning model, i.e. Residual Neural Network and Inception-v3 have been tested using some of the constructed image datasets. Furthermore, when the results of the proposed model have been compared with the results of some state-of-art works it has been revealed that the proposed model outperforms the compared previous models in term of classification accuracy, computational time, generality and classification mode.

Dogan, Deniz/0000-0003-2561-2946 WOS:000555566200010 This study aims to enhance the photocatalytic properties and stability of polyaniline (PANI) by preparing polyaniline-metal oxide composites. Polyaniline and polyaniline-metal oxide composites were synthesized via chemical polymerization method and characterized by using scanning electron microscopy, X-ray diffraction (XRD), energy-dispersive X-ray analysis, and Fourier transform infrared spectrometry. The morphological characteristics of the polymers synthesized in media with and without metal oxide are quite different from each other. These differences are due to the presence of metal oxides in the polymer structure, and the interactions between PANI-metal oxides, as mentioned in the XRD interpretations. The photocatalytic properties of polyaniline and each polyaniline-metal oxide composite were investigated using methylene blue (MB) under UV light and in the dark. (MB is one of the pollutant dyes found in wastewater.) The findings showed that photocatalytic property and stability of polyaniline can be enhanced by preparing the polyaniline-metal oxide composites. TheE(g)values of the selected metal oxides are around 3 eV values. The metal oxides, having the 3 eV energy bandgap range, exhibit better photocatalytic properties. Graphic It was aimed to investigate the photocatalytic properties and to increase the photocatalytic properties of polyaniline with the metal oxide. Polyaniline-metal oxide composites were synthesized and characterized. And their photocatalytic properties of each oxide composite were investigated by degradation of methylene blue under UV light and in dark media.

Materials and methods Thirty participants diagnosed with Graves' disease without ophthalmopathy and 30 healthy volunteers (control group) were prospectively examined between November 2018 and August 2019. SE and SWE findings in both groups were compared using the chi(2)test and the independent samplesttest. Results A statistically significant softening of the medial rectus muscle was observed in the SE patterns of the Graves' patients (p = 0.009). A statistically appreciable distinction was observed between the medial rectus muscle (7.64 +/- 2.1 and 9.20 +/- 1.7 kPa,p = 0.000) and the optic nerve (8.35 +/- 2.8 and 9.37 +/- 1.5 kPa,p = 0.019) in the SWE modulus of the Graves' patients and healthy volunteers. Conclusion SE and SWE can be used to identify structural alterations to the medial rectus muscle and optic nerve before clinically apparent Graves' ophthalmopathy has developed.

WOS:000551559000009 PubMed: 32792874 Introduction: Acitretin is a commonly used retinoid in dermatology. Although there are generally known side effects, the effects on the epiphyseal plaque and bone metabolism are not clear in the literature. Aim: To histopathologically investigate the effects on the epiphyseal plate and assess variations in bone metabolism caused by acitretin. Material and methods: Three groups were formed with 10 rats in each group. The 1st group (n = 10, 5 male, 5 female) were administered 10 mg/kg/day oral acitretin solution and the 2nd group (n = 10, 5 male, 5 female) were administered 3 mg/kg/day oral acitretin solution. The control group were given normal standard feed and water. Rats were sacrificed at the end of 4 weeks. The proximal tibias were excised and histopathologically and immunohistochemically assessed. Biochemical assessment was also carried out. Results: Staining with haematoxylin-eosin found reductions in the epiphyseal plate in the 1st and 2nd group compared to the control group, though this situation was not statistically significant. Immunohistochemical studies did not encounter Type II collagen in the epiphyseal bone, proliferative zone and hypertrophic zone in the control group, low dose acitretin solution group and high dose acitretin solution group. Type II collagen was not observed in osteoids and osteoblasts. Type I collagen was not observed in the hypertrophic zone and proliferative zone of any group. Conclusions: Our data show that though acitretin caused degeneration of the epiphyseal plate, it did not cause clear thinning and we identified no significant variations in bone metabolism markers.

The phenol ring is inclined by 45.73 (2)degrees from the plane of the aniline ring. In the crystal, molecules are linked along the b axis by O-H center dot center dot center dot N and C-H center dot center dot center dot O hydrogen bonds, forming polymeric chains. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the packing arrangement are from H center dot center dot center dot H (56.9%) and H center dot center dot center dot C/C center dot center dot center dot H (31.2%) interactions. The density functional theory (DFT) optimized structure at the B3LYP/ 6-311 G(d,p) level is compared with the experimentally determined molecular structure, and the HOMO-LUMO energy gap is provided. The crystal studied was refined as an inversion twin.

Evis, Zafer/0000-0002-7518-8162 WOS:000545315200013 PubMed: 31672424 Statement of problem. Recent commercial extended-pour irreversible hydrocolloid impression materials (EPIHIMs) claim to maintain dimensional stability up to 120 hours. However, data regarding their mechanical properties and performance after 120 hours of storage are lacking. Purpose. The purpose of this in vitro study was to test the elastic recovery, strain in compression, and tear strength properties of 5 commercially available EPIHIMs, immediately after preparation and after 120 hours of storage under specific storage conditions. Material and methods. A total of 150 specimens were prepared in accordance with the ISO 21563:2013 standard from 5 commercially available EPIHIMs (Blueprint Xcreme, Kromopan, Alginmax, Hydrogum 5, and Alginelle). The specimens were subjected to elastic recovery, strain in compression, and tear strength tests immediately after specimen preparation (n=5) and after 120 hours of storage inside clear plastic zipper bags held at 23 degrees C (n=5). Data were analyzed with a multivariate analysis of variance (MANOVA) test for brand and duration parameters. Normality of data was analyzed with the Shapiro-Wilk test. The Duncan test or Games-Howell test was used for multiple comparisons (alpha=.05). Results. Elastic recovery and strain in compression values of the EPIHIMs tested were affected by brand and duration parameters (P.05). Data distribution was normal except for Alginmax in terms of the elastic recovery values and Blueprint Xcreme in terms of the strain in compression values (P.05). However, 120 hours of storage led both to a statistically significant decrease in mean strain in compression values of the tested EPIHIMs (P.05) and a statistically significant difference among mean strain in compression values of the tested EPIHIM brands (P.05). However, statistically significant differences were present among mean tear strength values of the tested EPIHIM brands tested immediately after preparation (P

Onder, M Ercument/0000-0002-1488-616X; Altay, Berkan/0000-0003-0297-6501; Orhan, Kaan/0000-0001-6768-0176 WOS:000545324000029 PubMed: 32275899 Purpose: The main disadvantage of distraction osteogenesis is the prolonged treatment protocol. Recently, oxytocin (OT) has been found to have anabolic effects on bone metabolism. In this experimental study, the effects of OT on the mandibular distraction gap in rabbits at 2 different distraction rates were evaluated. Materials and Methods: This experimental study was conducted on 28 male New Zealand white rabbits. The animals were divided into 3 experimental groups and 1 control group. Group A (control group, n = 7) consisted of animals with distraction at a rate of 1 mm/day, and group B (n = 7) consisted of animals with a distraction rate of 2 mm/day; groups A and B received postoperative saline solution injection. Group C (n = 7) consisted of animals with distraction at a rate of 1 mm/day, and group D (n = 7) consisted of animals with a distraction rate of 2 mm/day; postoperative OT injection was performed in groups C and D. Results: Both histomorphologic and micro-computed tomography evaluations showed increased bone healing in the OT-treated groups. Conclusions: On the basis of the evaluation of both the histomorphometric and micro-computed tomographic data, systemic OT administration was found to increase new bone formation and bone healing with distraction osteogenesis.

DOGAN, Erdem/0000-0001-7802-641X WOS:000546566800002 Long short-term memory networks (LSTM) produces promising results in the prediction of traffic flows. However, LSTM needs large numbers of data to produce satisfactory results. Therefore, the effect of LSTM training set size on performance and optimum training set size for short-term traffic flow prediction problems were investigated in this study. To achieve this, the numbers of data in the training set was set between 480 and 2800, and the prediction performance of the LSTMs trained using these adjusted training sets was measured. In addition, LSTM prediction results were compared with nonlinear autoregressive neural networks (NAR) trained using the same training sets. Consequently, it was seen that the increase in LSTM's training cluster size increased performance to a certain point. However, after this point, the performance decreased. Three main results emerged in this study: First, the optimum training set size for LSTM significantly improves the prediction performance of the model. Second, LSTM makes short-term traffic forecasting better than NAR. Third, LSTM predictions fluctuate less than the NAR model following instant traffic flow changes.

Background: ‪Maturation is an important factor for exercise. The maturation effect on some anthropometric and motoric characteristics of students aged eight years was examined in this study. Material and methods: ‪535 primary education students voluntarily participated in this study. Anthropometric measurements (weight, height, sitting height, stroke length, stroke rate, leg length and body mass index), flexibility, handgrip strength, vertical jump (squat and countermovement jump), tapping (skipping) test paramaters (step frequency, flight times and contact times to ground of right and left foot, step/speed ratio), postural sway (anterior-posterior, medial lateral and total postural sway), visual reaction and reaction time, 20 meters sprint time, agility values were measured. The test parameters were compared in terms of gender and maturation level (early, normal and delayed maturation) by parametric (independent samples T-test, one way ANOVA) and non-parametric (Mann Whitney-U and Kruskal Wallis-H) tests. Results: A‪ significant difference was indicated between boy and girl students in most of the test parameters (p < 0.05). The analysis results indicated that students at early maturation level had better test values (p < 0.05). Conclusions: ‪The maturation factor positively affected some anthropometric and motoric parameters of students aged eight years.

WOS:000543953700001 PubMed: 32596805 In this retrospective study, we aimed to present important anatomical structures and distances for posterior fossa surgery by temporal multidetector computed tomography (MDCT). The temporal MDCT images of 317 adult patients (158 males and 159 females) were retrieved from the hospital's picture archiving and communication system (PACS). In the coronal temporal MDCT views, the cochlea-carotid canal and jugular bulb-mastoid bone outer surface were measured. In the axial MDCT views, the carotid canal-jugular bulb and carotid canal-posterior fossa distances were measured; the carotid canal and jugular bulb anterior-posterior (AP) and transverse dimensions were also measured. The bilateral cochlea-carotid canal, jugular bulb-mastoid bone outer surface, and right carotid canal-jugular bulb distances were significantly greater in the males than those in the females (p < 0.05). The carotid canal-posterior fossa distance was not different in both genders (p > 0.05). The carotid canal-jugular bulb and the carotid canal-posterior fossa distances were greater on the left side than those on the right side in both genders (p < 0.05). In males, the outer surface distance was greater on the left jugular bulb-mastoid bone than that on the right side of that bone (p < 0.05). The difference between the carotid canal AP dimensions was not significant between males and females (p > 0.05). However, the carotid canal transverse dimension, jugular bulb AP, and transverse dimensions were significantly greater in the males than those in the females, bilaterally (p < 0.05). In each gender separately, the carotid canal AP and transverse dimensions were greater on the left side and the jugular bulb AP and transverse dimensions were greater on the right side than those on the left side (p < 0.05). Positive correlations were found between the cochlea-carotid canal, the jugular bulb-mastoid bone outer surface, and the carotid canal-jugular bulb distances as well as between the jugular bulb-mastoid bone outer surface and the carotid canal-posterior fossa distances (p < 0.05). In older patients, the carotid canal-posterior fossa distances were shorter on the left side (p < 0.05). Vascular and neural localizations should be well understood in the operative area before applying the surgical approach in the posterior fossa. Computed tomography (CT) has a greater role in the evaluation of bone structures and vascular canals in this area.

Takci, Zennure/0000-0001-7257-5792 WOS:000539720000001 PubMed: 32433803 Background Data point to the importance of oxidative stress in rosacea. Glutathione S-transferases (GSTs) have substantial roles in a wide variety of oxidative stress-related conditions. Aim To evaluate the immunohistochemical staining characteristics of GST alpha (GSTA), mu (GSTM), pi (GSTP), and theta (GSTT) in patients with rosacea. Patients/Methods The study included 23 women and 7 men with rosacea (mean +/- SD age 49 +/- 11 year) and 15 healthy control subjects (10 women, 5 men; mean +/- SD age 47.86 +/- 10.88 year). For each patient, the average disease duration, disease subtype, ocular involvement, and severity score were recorded. A 3-mm punch biopsy was taken from the facial skin of each patient and control. Expression of GST isoenzymes was analyzed immunohistochemically. Results Expressions of GSTM1, GSTP1, and GSTT1 were significantly elevated in patients with rosacea compared to those in the control group (P = .0001,P = .0002,P < .0001, respectively). In the rosacea group, GSTT1 expression was significantly stronger than GSTP1 and GSTA1 expressions (P = .019,P < .0001, respectively). There were no significant associations between expressions of GST isoenzymes and gender, age, average duration of illness, disease subtype, ocular involvement, or severity score in the patient group (allP > .05). Conclusions In rosacea, the significant increase of GSTT1, GSTP1, and GSTM1 expressions might result from activation of GST as an outcome of extreme free radical generation from triggered neutrophils or ultraviolet vulnerability. These findings support the relevance of oxidant stress in the pathogenesis of rosacea.
