A 3D finite element analysis of stress distribution on different thicknesses of mineral trioxide aggregate applied on various sizes of pulp perforation
(Springer Heidelberg, 2020) Ozkurt-Kayahan, Zeynep; Turgut, B.; Akin, H.; Kayahan, M. B.; Kazazoglu, E.; Periodontoloji / Periodontology
Objectives The aim of this study was to evaluate the stress distribution on different thicknesses of mineral trioxide aggregate (MTA) placed on various widths of pulp perforations during the condensation of the composite resin material. Materials and methods The mandibular molar tooth was modeled by COSMOSWorks program (SolidWorks, Waltham, MA). Three finite elemental analysis models representing 3 different dimensions of pulp perforations, 1, 2, and 3 mm in diameter, were created. The perforation area was assumed as filled with MTA with different thicknesses, 1, 2, and 3 mm for each pulp perforation width, creating a total of 9 different models. Then, a composite resin material was layered on MTA for each model. A 66.7 N load was applied and an engineering simulation program (ANSYS, Canonsburg, US) was used for the analysis. Results were presented considering von Mises stress criteria. Results As MTA thickness increased, the stress values recorded within the area between pulp and MTA decreased. Strain was decreased when the thickness of MTA increased. Conclusions Stresses at MTA-pulp interface and strain on MTA decreased with the increase in MTA thickness.

ABSTRACT CAPACITY OF REGIONS AND COMPACT EMBEDDING WITH APPLICATIONS
(Springer, 2011) Shakhmurov, Veli
The weighted Sobolev-Lions type spaces W-p,gamma(l) (Omega; E) boolean AND L-p,L-gamma (Omega; E-0) are studied, where E-0, E are two Banach spaces and E-0 is continuously and densely embedded on E. A new concept of capacity of region Omega is an element of R-n in Wp,gamma(l)(Omega; E-0, E) is introduced. Several conditions in terms of capacity of region Omega and interpolations of E-0 and E are found such that ensure the continuity and compactness of embedding operators. In, particular, the most regular class of interpolation spaces E-alpha between E-0 and E, depending of alpha and l, are found such that mixed differential operators D-alpha are bounded and compact from W-p,gamma(l)(Omega; E-0, E) to E-alpha-valued L-p,L-gamma spaces. In applications, the maximal regularity for differential-operator equations with parameters are studied.

Aging Changes of the Superficial Fat Compartments of the Midface Over Time: A Magnetic Resonance Imaging Study
(Lippincott Williams & Wilkins, 2020) Cenkeri, Halime Cevik; Guduk, Sukran Sarigul; Cicek, Esin Derin
BACKGROUND Studies involving superficial facial fat compartments are few in number with conflicting results. Most of them involved small study groups and compared measurements between different populations of young and old subjects either on cadavers or living subjects. OBJECTIVE To clarify volumetric and dimensional changes in midfacial superficial fat compartment retrospectively in patients who underwent a repeat magnetic resonance imaging (MRI) without gross pathology. MATERIALS AND METHODS A total of 70 patients with a mean age of 60 years (range: 33-82 years) and a median elapsed time of 44.5 months (range: 32-64 months) between 2 MRIs were included. Magnetic resonance imaging scans were analyzed in the axial and sagittal planes to obtain measurements of the medial part of the superficial cheek fat. Superficial cheek fat was divided into 3 compartments. Thickness, width, and height were measured, and volumes were calculated for each compartment on both hemifaces. RESULTS Volume and thickness were decreased significantly in all compartments (p < .05). The width was decreased in superior and middle compartments, whereas increased in lower compartment indicating dislocation of the fat tissue (p < .05). Height was also significantly increased (p < .05). A subgroup analysis has shown that there was no significant difference between men and women. CONCLUSION This study clarifies that aging is associated with a significant decrease in superficial midfacial fat tissue volume and thickness both in women and men. The decrease in width in upper and middle compartments, but increase in lower compartment suggests a volume shift within superficial fat tissue.

Air Injection and Transillumination in Phonosurgery: A Novel Technique
(Mosby-elsevier, 2020) Kocak, Ismail; Alkan, Zeynep; Ovunc, Okan
Objectives/Hypothesis. The goal of this study was to introduce two novel techniques in phonomicrosurgery, air injection (AIR), and transillumination (TI), to improve the diagnosis and surgical excision of pathological tissue in vocal folds during suspension laryngoscopy while preserving the healthy tissue as much as possible. Study design. Prospective clinical case series. Methods. Thirty-four patients with benign vocal cord lesions who underwent phonomicrosurgery between January 2016 and May 2017 were evaluated. Pre- and intraoperative recordings were evaluated by three experienced laryngologists. Stroboscopic video images taken during the preoperative diagnosis and interoperative video recordings made before and after AIR and TI were performed were reviewed and compared. During the preoperative evaluation, the surgeons declared their surgical plans and noted changes while observing the intraoperative evaluation during AIR and TI. Results. Sixty-eight vocal folds were evaluated. The initial diagnosis was found to be consistent with the final diagnosis in only 10 patients (29.4%). The diagnoses of 29 vocal folds (42.6%) and the surgical plans changed after AIR and TI. In six cases, submucosal bands, additional morphological structures in the vicinity of the primary pathology, were observed; these could only be visualized with AIR and TI. AIR and TI revealed new pathologies in four vocal folds that were noted to be normal in the preoperative evaluation. Conclusion. AIR and TI are useful and promising techniques to identify undiagnosed lesions in vocal folds and to increase the success of minimally invasive phonosurgery.

Airborne pathogen projection during ophthalmic examination
(Springer, 2020) Bostanci Ceran, Basak; Karakoc, Alp; Taciroglu, Ertugrul
Purpose Microscale droplets act as coronaviruses (CoV) carriers in the air when released from an infected person and may infect others during close contact such as ophthalmic examination. The main objective of the present work is to demonstrate how CoV deposited droplets are projected during biomicroscopy and to discuss what kind of precautions should be taken in ophthalmic practice. Methods A coupled fluid-structure system comprising smoothed particle hydrodynamics and the finite element method has been built to assess the projection of droplets spreading from an infected person. Different conditions based on the maximum exit flow velocity from the infector's mouth during the ophthalmic examination were modeled. Results During exhalation, for which the exit flow is similar to 1000 mm/s, the average horizontal distance of the flow front was similar to 200 mm while individual particles can reach up to similar to 500 mm. In case of coughing or sneezing (corresponding to an exit flow of similar to 12,000 mm/s), the average horizontal distance of the flow front was similar to 1300 mm. Conclusion During the ophthalmic examination, the proximity to the patient's nose and mouth was observed to be less than the horizontal distance of flow front particles. Even though mounted breath shields are used, particles flew beyond the shield and contaminate the ophthalmologist. Compared with the current protective breath shields, the use of a larger shield with a minimum radius of 18 cm is needed to decrease viral transmission.

Analyses of Mossbauer experiments in a rotating system: Proper and improper approaches
(Academic Press inc Elsevier Science, 2020) Kholmetskii, Alexander L.; Yarman, Tolga; Yarman, O.; Arik, M.; Enerji Sistemleri Mühendisliği / Energy Systems Engineering
We examine various attempts to interpret the results of modern Mossbauer rotor experiments and show that the most recent approach developed by Podosenov et al. (0000) to understand these results implies an experimental configuration which has never been realized in the known experiments on this subject, and thus leaves the problem of the physical interpretation of the observed energy shift between emission and absorption lines in a rotating system under the framework of general relativity open.

Analysis of a Normalized Structure of a Complex Fractal-Fractional Integral Transform Using Special Functions
(Mdpi, 2024) Ibrahim, Rabha W.; Salahshour, Soheil; Pall-szabo, Agnes Orsolya
By using the most generalized gamma function (parametric gamma function, or p-gamma function), we present the most generalized Rabotnov function, called the p-Rabotnov function. Consequently, new fractal-fractional differential and integral operators of a complex variable in an open unit disk are defined and investigated analytically and geometrically. We address some inequalities involving the generalized fractal-fractional integral operator in some spaces of analytic functions. A novel complex fractal-fractional integral transform (CFFIT) is presented. A normalization of the proposed CFFIT is observed in the open unit disk. Examples are illustrated for power series of analytic functions.

Analysis of Entanglement Measures and LOCC Maximized Quantum Fisher Information of General Two Qubit Systems
(Nature Portfolio, 2014) Erol, Volkan; Ozaydin, Fatih; Altintas, Azmi Ali
Entanglement has been studied extensively for unveiling the mysteries of non-classical correlations between quantum systems. In the bipartite case, there are well known measures for quantifying entanglement such as concurrence, relative entropy of entanglement (REE) and negativity, which cannot be increased via local operations. It was found that for sets of non-maximally entangled states of two qubits, comparing these entanglement measures may lead to different entanglement orderings of the states. On the other hand, although it is not an entanglement measure and not monotonic under local operations, due to its ability of detecting multipartite entanglement, quantum Fisher information (QFI) has recently received an intense attraction generally with entanglement in the focus. In this work, we revisit the state ordering problem of general two qubit states. Generating a thousand random quantum states and performing an optimization based on local general rotations of each qubit, we calculate the maximal QFI for each state. We analyze the maximized QFI in comparison with concurrence, REE and negativity and obtain new state orderings. We show that there are pairs of states having equal maximized QFI but different values for concurrence, REE and negativity and vice versa.

Analysis of the effects of subthalamic nucleus deep brain stimulation on somatosensation in Parkinson's disease patients
(Springer-verlag Italia Srl, 2020) Huzmeli, Esra Dogru; Yilmaz, Atilla; Okuyucu, Esra
Objective Despite the subthalamic nucleus (STN) deep brain stimulation (DBS) is a treatment commonly used to ameliorate the motor symptoms of Parkinson's disease (PD), its effects on somatosensation is unclear. The purpose of this study was to investigate the potential effects of DBS on temperature, proprioceptive, tactile, exteroceptive, pain and cortical sensations, and odor identification in PD patients. Methods The study included 14 patients (with a mean age of 59.78 +/- 11.03 years; range, 44-70 years) with idiopathic PD who underwent DBS surgery for movement disorders caused by PD at the same Neurosurgery Department. All patients were tested while DBS was turned on (DBS-ON) and off (DBS-OFF). To clearly observe the effect of removing stimulation off, DBS devices were turned off by experimental clinical personnel for a minimum duration of 30 min prior to examination. Temperature, proprioceptive, tactile, exteroceptive, pain and cortical sensations, and odor identification were examined. Results We found that two-point discrimination was significantly lower during DBS-ON than DBS-OFF (p = 0.031). Tactile sensation and kinesthesia deviation degree were lower during DBS-ON than DBS-OFF, but were non-significant (p > 0.05). The number of correct answers on an assessment of graphesthesia was higher during DBS-ON, but was non-significant as well (p > 0.05). Odor identification was better during DBS-OFF. Conclusions DBS may have an effective role to improve somatosensation and DBS-related benefits may not be explained by improvements in motor function alone, but rather by enhanced somatosensory processing. Further studies with larger study groups are needed.

(Wiley, 2022) Gulmez, Gizem; Sen, Ali; Sekerler, Turgut; Algul, Fatma Kader; Cilingir-Kaya, Ozlem Tugce; Sener, Azize; Tıbbi Biyokimya / Medical Biochemistry
The prothrombotic and inflammatory state plays a significant role in the occurrence of cardiovascular complications in type 2 diabetes mellitus. In this study, the antidiabetic, anti-inflammatory, and antiplatelet potentials of the extracts obtained from Ribes rubrum were investigated. The antidiabetic, anti-inflammatory, and antioxidant activities of the ethanol and water extracts of R. rubrum were evaluated by in vitro methods. The total phenolic and flavonoid contents were also determined. The experimental diabetes model in rats was induced with streptozotocin (STZ). After hyperglycemia occurred, the ethanol extracts of R. rubrum (RRE, at 100 mg/kg and 500 mg/kg doses) were administered to the treatment groups for 14 days. Blood glucose, lipid profile, plasma, and pancreas tumor necrosis factor-alpha (TNF-alpha) levels were determined and compared at the end of the experiments. P-selectin levels and mitochondrial membrane polarization (MMP) of platelets were also measured. In vitro study, the RRE showed potent anti-inflammatory activity. Administration of RRE (at 100 mg/kg doses) to diabetic rats lowered blood glucose level insignificantly. The results showed that there was an increment in levels of TNF-alpha in plasma and pancreas tissue of the diabetic group compared to the control group. R. rubrum extract regulated and normalized their levels in plasma and pancreatic tissue. RRE at both doses significantly decreased platelet P-selectin levels and prevented STZ-induced loss of MMP in platelets. The results of current research indicate that RRE extract has potent anti-platelet and anti-inflammatory effects and may be beneficial in preventing diabetic complications. Practical applications Hyperglycemia causes dyslipidemia, advanced oxidative stress, platelet activation, and inflammation in diabetes mellitus. Plants with various medicinal properties are of worldwide interest for the treatment of diseases due to their biological activities. In this study, the antidiabetic, anti-inflammatory, and antioxidant effects of extracts of Ribes rubrum (%100 ethanol, 50% ethanol, water) were evaluated by in vitro and in vivo methods. The diabetes model was induced with streptozotocin (STZ). The rats were divided into control, diabetic control, R. rubrum-100 mg/kg, and R. rubrum-500 mg/kg doses groups. Blood glucose levels, tumor necrosis factor-alpha (TNF-alpha), platelet P-selectin levels, mitochondrial membrane polarization of platelets were examined. The present study has shown that R. rubrum has anti-inflammatory and antiplatelet activity. R. rubrum may be beneficial in the prevention and treatment of DM complications due to its anti-inflammatory and antithrombotic effects.

An appropriate artificial intelligence technique for plastic materials recycling using bipolar dual hesitant fuzzy set
(Nature Portfolio, 2024) Ramya, Lakshmanaraj; Thilagasree, Chakkarapani Sumathi; Jayakumar, Thippan; Peter, Antony Kishore; Akhir, Emelia Akashah P.; Ferrara, Massimiliano; Ahmadian, Ali
Plastic recycling has become more important than ever as the globe struggles with growing environmental issues. This research explores the significant environmental impact of recycling plastic and its growing relevance. The pervasive material known as plastic presents a complex risk to both human health and ecosystems in contemporary life. It exacerbates problems including marine pollution, habitat damage, and wildlife entanglement because of its persistence in landfills and seas, which leads to serious ecological deterioration. In addition, producing plastic uses a lot of energy and produces a lot of greenhouse gas emissions, which exacerbate climate change. Through the use of multi-criteria decision making (MCDM), this study emphasizes how vital it is to support recycling activities in order to protect the environment and promote a sustainable future. The elimination and choice ex-pressing reality (ELECTRE) approach is used to rank the alternatives in this proposed research study that employs bipolar dual hesitant fuzzy sets (BDHFs). The most efficient and versatile outranking method for making decisions is the BDHF-ELECTRE approach. The weights of environment, economic, social, technical, and finally safety is computed using the entropy distance metric. The economic factor received the highest score of 0.2945 among the other factors since economic considerations are crucial in choosing the most efficient plastic recycling method, as they ensure sustainability, cost-effectiveness, resource allocation, and overall feasibility in managing plastic waste. The decision-makers determined that the mechanical recycling approach ought to be prioritized over all others for the efficient recycling of plastic waste. The robustness of the system is examined in the sensitive and comparative analyses. The proposed MCDM technique thus presents a viable solution, mitigating the adverse effects of plastic waste by conserving resources, reducing energy consumption, and curbing pollution.

Artificial neural network modeling of thermal characteristics of WO3-CuO (50:50)/water hybrid nanofluid with a back-propagation algorithm
(Elsevier, 2024) Qu, Yiran; Jasim, Dheyaa J.; Sajadi, S. Mohammad; Salahshour, Soheil; Khabaz, Mohamad Khaje; Rahmanian, Alireza; Baghaei, Sh.
Thermophysical properties such as thermal conductivity (knf) make the use of fluid suitable for heat transfer. Fluids such as water have limited applications due to their low thermal conductivity. One of the new methods to improve the properties of fluids is to add nanoparticles with high thermal conductivity and create a nanofluid. Nanofluids combine the suspension of two or more nanoparticles in a base fluid or the suspension of hybrid nanoparticles in a base fluid. This study investigates the thermal behavior of WO3-CuO (50:50)/water nanofluid using an artificial neural network (ANN) and back -propagation algorithm. The results show that increasing the volume fraction of nanoparticles (phi) (due to increasing the surface -to -volume ratio) increases the knf. In this study, ANN modeling for WO3-CuO/water (50:50) hybrid nanofluid was performed to investigate the effect of nanofluid on knf. These two important parameters are phi and temperature. The results show that increasing the phi increases the knf due to increasing the surface -to -volume ratio and the collision between nanoparticles. Increasing the temperature shows a similar effect and improves the knf by increasing the interaction between the nanoparticles. The effect of temperature on the knf is more significant than the phi, equal to 16.33% and 6.72%, respectively. Function parameters such as correlation and error value for hidden layer 7 and 12 neurons are about 0.982, 0.981, and 10-6, respectively. As a result, ANN models offer acceptable performance in estimating knf, and the correlation coefficients and error values are 0.96 and 10-6, respectively. Given the absolute error value, it can be concluded that the proposed models can predict the knf of WO3-CuO (50:50)/water hybrid nanofluid.

ObjectiveTo investigate the comprehensive effects of daily chronic asprosin administration on various pubertal and reproductive parameters in female rats. This study aims to elucidate the role of asprosin in regulating the onset of puberty and its influence on hormonal profiles and ovarian histology.MethodsAsprosin was administered intraperitoneally (i.p.) at a dose of 500 ng/kg daily for eight weeks. Hormonal assays and histological analyses were performed to evaluate the effects of asprosin on the onset of puberty and reproductive function.ResultsDaily chronic administration of asprosin accelerated the onset of the first oestrus. Hormonal assays revealed significant elevations in serum levels of Follicle-Stimulating Hormone (FSH) and Oestradiol (E2), while Inhibin B levels decreased. Histological evaluations demonstrated an increased number of primary and secondary follicles in ovarian tissue, without affecting primordial follicle counts or reproductive organ weights.ConclusionsRole of adipokines in regulating puberty and reproductive function has increasingly gained recognition. This study aimed to provide the first comprehensive examination of the effects of daily chronic asprosin administration on pubertal and reproductive parameters in female rats. Utilising hormonal assays and histological analyses, asprosin was administered intraperitoneally (i.p.) at a dose of 500 ng/kg, daily, for eight weeks. Our findings revealed that daily chronic administration of asprosin accelerated the onset of the first oestrus. Hormonal assays showed significant elevations in serum levels of Follicle-Stimulating Hormone (FSH) and Oestradiol (E2), while Inhibin B levels decreased. Histological evaluations demonstrated an increased number of primary and secondary follicles in ovarian tissue, without affecting primordial follicle counts or reproductive organ weights. These results provide new insights into asprosin's role in advancing the age of first oestrus and modulating hormonal profiles, thereby offering potential benefits to the female reproductive system.

Assessment of the trabecular structure of mandibular condyles in patients with temporomandibular disorders using fractal analysis
(Elsevier Science inc, 2017) Arsan, Belde; Kose, Taha Emre; Cene, Erhan; Ozcan, Ilknur
Objectives. The aim of this study was to evaluate changes in the trabecular structure of the mandibular condyle in patients with temporomandibular disorders (TMDs) using fractal analysis. Study Design. A total of 100 patients ages 18 to 73 years were clinically assessed using the Diagnostic Criteria for Temporomandibular Disorders. The control group was age-and sex-matched with the patient group. Panoramic radiographs were obtained using a Kodak 8000 digital device with 73 kVp and 5 mA fixed parameters. The degree of degeneration in the mandibular condyles was calculated. Regions of interest (84 X 84 pixels) were selected within the cortical boundary of the mandibular condyle, and the fractal dimension (FD) was calculated using ImageJ version 1.48. Results. Radiographic degenerative changes were more frequently present and more severe in the patient group (P < .001). The mean value of FD was 1.22 +/- 0.06 in the patient group and 1.25 +/- 0.06 in the control group (P = .001). A significant decrease in FD was observed (P = .001) in the left temporomandibular joints of the patient group, whereas a nonsignificant decrease in FD was observed in the right temporomandibular joints (P = .073) as degenerative changes increased. Conclusions. Lower FD values were associated with more severe degenerative changes in the patient group. The trabecular structure of condyles in patients with TMD exhibited decreased complexity when erosive and sclerotic changes were evident. As a result, fractal analysis enhanced the use of panoramic radiography in detecting degenerative changes in patients with TMD. (Oral Surg Oral Med Oral Pathol Oral Radiol 2017;123: 382-391)

Association between Pityriasis Rosea (PR) and HHV-6/HHV-7 Infection: Importance of Sample Selection and Diagnostic Techniques
(Mdpi, 2024) Kurc, Mine Aydin; Erfan, Gamze; Kaya, Ayse Demet; Gulen, Dumrul; Oznur, Meltem; Yanik, Mehmet Emin; Tıbbi Mikrobiyoloji / Medical Microbiology; Tıbbi Mikrobiyoloji / Medical Microbiology
Recent studies have focused on the role of human herpesvirus 6 (HHV-6) and human herpesvirus 7 (HHV-7) in PR etiology with varying results. In our study, with the approach that the discrepancy between the results may be related to the different samples and techniques used, we aimed to clarify the etiology by examining tissue and plasma samples using molecular methods and evaluating the results together with serological parameters. Skin biopsies and plasma samples of twenty-five PR patients were tested to detect HHV-6 and HHV-7 DNA using calibrated quantitative real-time polymerase chain reaction (CQ RT-PCR). IgG and IgM antibodies against HHV-6 and HHV-7 were tested by enzyme-linked immunosorbent assay and indirect immunofluorescence. Of the patient group, 64% were positive for HHV-6 IgG without IgM positivity. HHV-6 DNA was present in seven tissue and ten plasma samples. HHV-7 positivity was 100% and 12% for IgG and IgM antibodies, respectively. HHV-7 DNA was detected in four tissue samples and one plasma sample. Patients with HHV-7 DNA-positive plasma and tissue samples had also HHV-7 IgM antibodies. In conclusion, our results seem to support the role of HHV-6/HHV-7 in the etiology of PR. To clarify the etiology of PR and avoid confusion, the collection of different biological materials simultaneously and the usage of CQ RT-PCR as a diagnostic technique are recommended.

Attitudes of Married Muslim Women Regarding Family Planning Methods During the COVID-19 Pandemic in Western Turkey
(Springer, 2021) Dal, Nursel Alp; Beydag, Kerime Derya
COVID-19 had negative effects upon family planning. Women cannot visit healthcare facilities because of a fear of curfew-related sanctions or exposure to COVID-19. It is seen that religious beliefs are influential especially in terms of family planning method preference and having abortions. This study was conducted to determine the attitudes of married Muslim women regarding family planning methods during the COVID-19 pandemic period. The descriptive and cross-sectional study was conducted with 611 married Muslim women who presented to the family planning outpatient clinic of a public hospital in Western Turkey between 1 September 2020 and 1 March 2021. The mean Family Planning Attitude Scale score of the women was found to be 137.53 +/- 27.11. It was observed that, as the mean age of the women increased, their family planning attitudes were more positive, and as their number of pregnancies, abortions and living children increased, their attitudes were more negative (p < 0.05). Women do not want to get pregnant during the pandemic process. This is because the effects of COVID-19 on both themselves and the baby to be born are not known, which worries women. Therefore, in order to transform positive attitudes regarding family planning into behavior, it is recommended to provide effective training and consultancy services during the pandemic period.

An augmented fuzzy decision support system to analyse compatible cosmetic face masks for various complexions
(Wiley, 2024) Brainy, Joseph Raj Vikilal Joice; Narayanamoorthy, Samayan; Kalaiselvan, Samayan; Saraswathy, Ranganathan; Ahmadian, Ali; Senu, Norazak; Jeon, Jeonghwan
Beauty face masks (BFM) are becoming increasingly popular among both men and women since they provide quick refreshment and nurture the skin. Given the wide range of skin types and the chemicals used in their formulation, it can be difficult to find a product that not only complements the skin type but is also free of potentially harmful ingredients that could endanger the consumer's health. When dealing with ambiguous situations, the multi-attribute decision making (MADM) approach combined with fuzzy set theory is more effective. Type-2 fuzzy sets (T2FS) provide greater flexibility in dealing with uncertainty in real-world issues since they are characterised by a main and secondary membership function. In this research, we present the innovative idea of type-2 linear diophantine fuzzy set (T2LDFS) as an intriguing tool for capturing expert reluctance about an issue. For analysing the discussed problem, a hybrid fuzzy VIKOR enhanced with the proposed fuzzy logic is suggested. A sensitivity and comparative analysis is carried out to establish the validity of the recommended approach.
