Patterns of balancing and compensating primary tooth extractions among paediatric dentists
No full textAbstract
Introduction Balancing and compensating extractions (BCEs) of primary teeth aims to minimise the development of
more severe malocclusions and reduce the need for subsequent complex orthodontics.
Purpose To assess the demographics, practice characteristics and clinical preferences of United Kingdom paediatric
dentists for BCEs of primary teeth.
Methods All members of the British Society of Paediatric Dentistry were sent an electronic questionnaire. Questions
offered frequency options (always/frequently, often/sometimes and rarely/never) for a range of clinical scenarios in
patients up to five years and between 6–9 years.
Results Of the 288 specialists invited, 67 (23.3%) completed the questionnaire. Respondents were mostly female
(n= 55; 82.1%), with most working in secondary care (n= 51; 77.3%). The majority (n= 54; 81.8%) supported the
application of guidelines. A total of 39 paediatric dentists (58.2%) always/frequently encountered BCEs, with 31
(46.2%) performing BCEs in over 40 patients in the past year. Additionally, 40 respondents (59.7%) reported always/
frequently complying with guidelines. Data from 65 respondents indicates that 83.6% (n= 56) rarely/never made
referrals to an orthodontist, while 65.7% (n= 44) rarely/never consulted an orthodontist (p<0.001).
Conclusions There was variation across clinical scenarios, with good adherence to guidelines in BCEs of primary teeth
among paediatric dentists. However, there was limited interdisciplinary collaboration with orthodontist
Gender disparity in authorship in high-impact obstetrics and gynecology journals over twenty years
Full text linkAbstract
In the present study, we evaluate the proportion of women authorship in the field of obstetrics and gynecology research by assessing five prominent journals spanning 2001-2021, analyzing article types, study types, sub-specificities, and regions. Our outcomes demonstrate a significant increase in women's authorship over time, highlighting progress in promoting gender equality. However, the rate of first and most senior women authors remains relatively unchanged. Notably, we determine a rise in the proportion of first authors who are women in experimental studies but not in studies that require surgical practice. This study sheds light on the challenges faced by women in scientific pursuits. Our study suggests that systemic barriers, prejudices, and inequalities likely continue to hinder gender equality in our discipline. By emphasising the continuance of this problem, we intend to encourage collective awareness and action. Together, we can transcend gender disparities and create a space where every voice, regardless of gender, can flourish. Through our study, we hope to inspire future generations and ignite change within the field of obstetrics and gynecology. By valuing and amplifying diverse perspectives, we can create a future where gender equality is the norm, enabling scientific discovery to reach new heights
ZnO-NF/Graphene/Nafion as electrode platform for some pharmaceutical active ingredients sensor and energy storage applications
Full text linkABSTRACT
This paper presents a simultaneous sensor for the detection of paracetamol (PAR)and ibuprofen (IBU). The sensor
is based on a ZnO nanoflower/Graphene/Nafion coated glassy carbon electrode (ZnO NF/GR/Nafion/GCE) and a
supercapacitor electrode with the same electrode component. The morphological characterisation of the pre
pared sensor and supercapacitor electrode was conducted via scanning electron microscopy (SEM), structural
characterisation by X-ray diffraction spectroscopy, chemical characterisation by Fourier transform infrared
spectroscopy (FT-IR) and Raman analysis. The electroactivity and selectivity of the ZnO NF/GR/Nafion sensor
platform towards IBU and PAR were simultaneously investigated by cyclic voltammetry (CV), differential pulse
voltammetry (DPV) and electrochemical impedance spectroscopy (EIS). Electrochemical tests of the sensor were
conducted in a three-electrode electrochemical system in 0.1 M B-R buffer (pH 4.0). The linear ranges of the ZnO
NF/GR/Nafion sensor towards PAR and IBU were determined in the range of 1.0 and 1000.0 μM. The detection
limits for PAR and IBU were calculated as 0.28 µM and 0.31 µM, respectively. In real sample analyses, the ef
ficiency of the investigated sensor in different drug formulations was found to respond to PAR and IBU with high
recovery (99.05 % and 103.35 %). The supercapacitor electrode was prepared by changing the same electrode
component, amounts and ratios of the components. The performance of the supercapacitor electrode was
investigated in the potential range from 0 V to 1.2 V in PVA-H2SO4 electrolyte. The supercapacitor electrode
demonstrated a specific capacitance of 488.1 F g− 1 at a scan rate of 5 mV s
− 1 and a capacitance value of
405.5 F g− 1 at a current density of 7 mA.cm− 2
. In this study, the ZnO NF/GR/Nafion/GCE hybrid electrode
produced is used as both sensor and supercapacitor electrode material and operates in dual mode. The pro
duction method is cheap and simple, and no additional modifications are needed in the production of electrode
components. In this study, for the first time in the literature, the electrode material with ZnO NF/GR/Nafion/
GCE component is used in the analysis of some pharmaceutical active ingredients and in supercapacitor
applications
Potential role of terpenes in recovery from olfactory dysfunction with olfactory training: a review
Full text linkAbstract
The sense of smell is an important part of everyday life, yet many people around the world live with olfactory dysfunc-
tion or smell loss. The most common causes of olfactory dysfunction include upper respiratory tract infections, sinus dis-
eases, and traumatic brain injury. Current treatment options are limited, and olfactory training is the most commonly used
method clinically. Terpenes are volatile organic compounds found in plants that exhibit anti-inflammatory, neuroprotective,
and anti-cancer effects. This review addresses the potential benefits of terpene use in olfactory training and proposes the
development of a new terpene-centered training protocol. Terpenes have been shown to provide anti-inflammatory effects
by inhibiting the NF-κB signaling pathway and may modulate olfactory receptors. Furthermore, they have the potential
to provide neuroprotection, tissue regeneration, and neuroprotection by interacting with the endocannabinoid system and
various cellular signaling pathways. This study aims to further understand the effects of terpenes in the treatment of olfac-
tory dysfunctions and to develop new strategies to increase the efficacy of olfactory training
Evaluation of Thrombomodulin, Heart-Type Fatty-Acid-Binding Protein, Pentraxin-3 and Galectin-3 Levels in Patients with Myocardial Infarction, with and Without ST Segment Elevation
Full text linkAbstract: Background: Medical history, ECG findings and cardiac markers are used in
the diagnosis of myocardial infarction (MI). Biomarkers used especially for the diagnosis
of MI include high-sensitivity troponins (hsTns), creatine kinase-MB (CK-MB), lactate
dehydrogenase (LDH), myoglobin, cardiac myosin-binding protein C and new cardiac
biomarkers. This study evaluated the levels of serum thrombomodulin (TM), heart-type
fatty-acid-binding protein (H-FABP), pentraxin-3 (PTX-3) and galectin-3 (Gal-3) to determine their utility in distinguishing between ST-elevation myocardial infarction (STEMI)
and non-ST-elevation myocardial infarction (NSTEMI). Methods: This study included a
total of 180 patients (90 patients with acute STEMI and 90 patients with NSTEMI) who
presented to the Gaziosmanpa¸sa Training and Research Hospital, Cardiovascular Surgery
and Emergency Department, with ischemic chest pain lasting longer than 30 min. Ninety
healthy volunteers were included as the control group. Results: Serum levels of N-terminal
pro-brain natriuretic peptide (NT-proBNP), TM, H-FABP, PTX-3 and Gal-3 were significantly different across the STEMI, NSTEMI and control groups (p < 0.001). Strong positive
correlations were observed between NT-proBNP and TM, H-FABP, PTX-3 and Gal-3 in the
STEMI group. ROC analysis demonstrated excellent diagnostic accuracy for these biomarkers in distinguishing STEMI from NSTEMI and control groups. Conclusions: Vascular
inflammation plays an important role in the pathophysiology of STEMI and NSTEMI. A
comprehensive cardiac biomarker panel enhances diagnostic accuracy and risk stratification, particularly when distinguishing between STEMI and NSTEMI. The biomarkers
hs-TnI, CK-MB, NT-proBNP, TM, H-FABP, PTX-3 and Gal-3 offer complementary information when used together as a panel. Further research and validation are essential to
establish standardized protocols for their widespread use
Comparative analysis of dimensional trueness and adaptation of 3-unit monolithic zirconia restorations fabricated with subtractive and additive technologies
No full textPurpose The purpose of this study was to assess the dimensional trueness and fit of 3-unit monolithic zirconia restorations fabricated using various additive manufacturing (AM) techniques-namely, stereolithography (SLA), digital light processing (DLP), and lithography-based ceramic manufacturing (LCM)-in comparison with the computer numerical control (CNC) method. Materials and Methods A total of 32 three-unit posterior fixed partial dentures (FPDs) were fabricated using 3 different additive AM methods (SLA, DLP, and LCM) and CNC as the control group. In all groups, 3 mol% yttria-stabilized tetragonal zirconia polycrystalline (Y-TZP) was used. The restorations, the restorations placed on the model, and the model itself were digitized. For the purpose of trueness and internal fit analysis, all STL datasets were imported into a high-precision metrology-grade 3-dimensional inspection software (Geomagic Control X 2022; 3D Systems) and virtually divided into four regions: intaglio, occlusal, axial, and marginal. Surface deviations were analyzed by using the root mean square (RMS) method, while the triple scan method was used for internal fit. Obtained data were then computed by using two-way ANOVA, followed by Bonferroni and Tukey post hoc tests (alpha = 0.05). Results SLA, CNC, and LCM provided similar and clinically acceptable marginal and internal trueness (p > 0.05). Conversely, the DLP method exhibited a significantly higher discrepancy in all regions, particularly in the marginal and intaglio surfaces (p <= 0.001). The lowest overall RMS deviation was observed in the SLA group (39.88 +/- 4.84 mu m), while the highest internal gap was found in the DLP group (218.29 +/- 11.88 mu m). Conclusion Additive manufacturing methods affected the fabrication trueness and fit of the 3-unit zirconia FPDs. Since the restorations produced by the DLP method had higher RMS and internal gap values, adjustment is required prior to clinical use
Examination of the effect of exercise training with upper extremity blood flow restriction on upper extremity muscle strength and performance in basketball players
No full textBasketbol, yüksek seviyede fiziksel uygunluk ve sportif becerilerinin sergilenmesini gerektiren zorlu bir spordur. Klasik direnç antrenmanlarının aksine kuvvet ve hipertrofi kazanımı için egzersiz esnasında kasa giden kanı kısıtlamayı amaçlayan KAKE ile arteriyel oksijen basıncının %40-80'ini kısıtlayarak ve 1-RM'nin %20-40'ında yapılması yeterlidir. Çalışmamızın amacı basketbolcularda üst ekstremiteye uygulanan KAKE'nin üst ektremite kas kuvveti ve performansına olan etkilerini incelemektir. Çalışmamıza 18-25 yaş arasındaki 11 sporcu katıldı. Çalışmamız quasi-experimental dizaynında yürütüldü. Sporculara ilk değerlendirmenin ardından üç hafta rutin antrenman programları uygulandı ve ikinci değerlendirmeler yapıldı. Kan akımı kısıtlayıcı egzersizler haftada bir gün direnç antremanı ile beraber ve iki gün saha içi egzersizler sırasında olmak üzere toplam üç hafta uygulandı ve üçüncü değerlendirmeler ile çalışma tamamlandı. Katılımcıların sosyodemografik bilgileri sorgulandı, kas kuvveti (1-RM), kavrama kuvveti (el dinamometresi), hız (20 metre sprint testi), çeviklik (T- Çeviklik Testi), spora özgü performans (serbest atış testi), yorgunluk (Modifiye Borg Ölçeği) ve değişim ve memnuniyet (Global Değişim Ölçeği-GDÖ) parametreleri program öncesi ve sonrasında değerlendirildi. Çalışmanın sonunda sporcuların 20 metre Sprint Testi süresi ve T Çeviklik Testi süresi hariç diğer primer sonuç ölçümlerinde zaman etkisi anlamlı değildi. Üst ekstremite kas kuvveti ve spora özgü performans parametrelerinde zamana bağlı artış görüldü fakat istatistiksel olarak anlamlı değildi. Basketbolcularda üst ekstremite kan akımı kısıtlayıcı egzersiz uygulamasının daha düşük yüklerde uygulanmasına rağmen kas kuvveti, kavrama kuvveti ve spora özgü performans parametrelerini iyileştirme potansiyeli olduğu görülmüştür. Anahtar Kelimeler: Basketbol; Kan akımı kısıtlayıcı egzersiz; PerformansBasketball is a challenging sport that requires a high level of physical fitness and athletic skills. Unlike classical resistance training, BFR aims to restrict blood flow to the muscle during exercise for strength and hypertrophy gains, and it is sufficient to perform it by restricting 40-80% of arterial oxygen pressure and 20-40% of 1-RM. . The aim of our study is to examine the effects of upper extremity BFR on upper extremity muscle strength and performance in basketball players. Eleven athletes between the ages of 18-25 participated in our study. Our study was conducted in a quasi-experimental design. After the first assessments, routine training programs were applied to the athletes for three weeks and second assessments were made. Blood flow restriction exercises were applied for a total of three weeks, one day a week with resistance training and two days during field exercises, and the study was completed with the third assessments. The participants' sociodemographic information was questioned, muscle strength (1-RM), grip strength (hand dynamometer), speed (20-meter sprint test), agility (T- Agility Test), sport-specific performance (free throw test), fatigue (Modified Borg Scale) and change and satisfaction (Global Change Scale-GROC) parameters were evaluated before and after the program. At the end of the study, except for the 20-meter Sprint Test time and T Agility Test time, there was no significant time effect in the other primary outcome measures. A time-dependent increase was observed in upper extremity muscle strength and sport-specific performance parameters, but it was not statistically significant. It was observed that the upper extremity blood flow restrictive exercise application in basketball players had the potential to improve muscle strength, grip strength and sport-specific performance parameters, despite being applied at lower loads.

Rogue waves in diatomic acoustic metamaterials with damping effect
No full textThe paper addresses the damping effects on MI and on Rogue waves in diatomic acoustic metamaterials. Through the semi-discrete approximation method, we show that the network can be governed by a new form of the generalized coupled nonlinear Schr & ouml;dinger equation (CNLSE). In the linear stability analysis, we generate the MI growth rate, and we assess the damping effect on the MI spectrum. The combination of similarity and Darboux transformations help us to obtain rogue wave solutions (RWs). The acquired RWs are plotted and we observe remarquable influence of the damping effect on their intensities
Floortime müdahalesi ve duyu bütünleme terapisi uygulanmış duyusal işlemleme bozukluğu olan çocuklarda uyku ve duyusal işlemleme becerilerinin değerlendirilmesi
No full textErgenekon, D. (2025). Floortime Müdahalesi ve Duyu Bütünleme Terapisi Uygulanmış Duyusal İşlemleme Bozukluğu Olan Çocuklarda Uyku ve Duyusal İşlemleme Becerilerinin Değerlendirilmesi. Yüksek Lisans Tezi, Biruni Üniversitesi Lisansüstü Eğitim Enstitüsü. Bu çalışmanın amacı, duyusal işlemleme bozukluğu olan çocukların uyku düzeni ve duyusal becerilerine yönelik daha önce uygulanmış terapötik süreçlerin etkilerini retrospektif olarak değerlendirmektir. Kidino Akademi'ye başvuran, 3–6 yaş aralığındaki 60 çocuğun (30 çalışma, 30 kontrol grubu) klinik kayıtları incelenmiştir. Çalışma grubunu Floortime ve duyu bütünleme terapisi almış çocuklar; kontrol grubunu ise yalnızca duyu bütünleme terapisi almış çocuklar oluşturmuştur. Değerlendirme sürecinde ebeveynlerce doldurulan demografik formlara ek olarak Çocuk Uyku Alışkanlıkları Anketi, Pittsburgh Uyku Kalitesi İndeksi ve Dunn Duyu Profili kullanılmıştır. Her iki grubun başlangıç verilerinin homojen dağıldığı istatistiksel analizle doğrulanmıştır. İkinci değerlendirmeler, araştırmacı tarafından aynı ölçeklerin ebeveynlere yeniden uygulanmasıyla gerçekleştirilmiştir. Sonuçlara göre, Floortime ve duyu bütünleme terapisi uygulanan çocukların uyku süresi artmış (p < .001), uykuya geçiş süresi kısalmış (p < .01), gece uyanıklık süresi azalmış (p < .001) ve duyusal işlemleme puanlarında anlamlı gelişmeler gözlemlenmiştir (p < .001). Bulgular, Floortime'ın sosyal-duygusal gelişimi destekleyen yapısının duyusal regülasyon ve uykuya geçişte olumlu etkiler yarattığını göstermektedir. Floortime'ın ebeveyn katılımını esas alması, çocuğun duygusal regülasyonuna ve ebeveynin destekleyici tutumuna katkı sağlamıştır. Kontrol grubunda da benzer yönde gelişmeler izlenmiş; bu durum, duyu bütünleme terapisinin tek başına da etkili olabileceğini göstermektedir. Ancak Floortime'ın eklenmesiyle bu gelişmelerin daha belirgin ve bütünsel olduğu görülmüştür. İki yöntemin birlikte kullanımı, çocukların çok yönlü gelişimsel ihtiyaçlarına daha bütüncül bir yanıt sunmuştur.Ergenekon, D. (2025). An Evaluation of Sleep and Sensory Processing Skills in Children with Sensory Processing Disorder Receiving Floortime and Sensory Integration Therapy. Master's Thesis, Biruni University Institute of Graduate Studies. This study aims to retrospectively evaluate the effects of previously implemented therapeutic processes on the sleep patterns and sensory processing skills of children with sensory processing disorder. Clinical records of 60 children aged between 3 and 6 years (30 in the study group and 30 in the control group) who applied to Kidino Akademi were reviewed. The study group included children who had received both Floortime and sensory integration therapy, while the control group consisted of those who had received only sensory integration therapy. Along with parent-completed demographic forms, the Children's Sleep Habits Questionnaire, the Pittsburgh Sleep Quality Index, and the Dunn Sensory Profile were used in the evaluation. Statistical analyses confirmed that the baseline data were homogeneously distributed across groups. The second assessments were conducted by re-administering the same scales to the same children's parents. According to the findings, children who received both Floortime and sensory integration therapy showed a significant increase in sleep duration (p < .001), a decrease in sleep onset latency (p < .01), a reduction in nighttime awakenings (p < .001), and significant improvements in sensory processing scores (p < .001). These results suggest that Floortime, with its focus on supporting socioemotional development, had a positive effect particularly on sensory regulation and the transition to sleep. The parent-involved nature of the Floortime approach contributed not only to the child's emotional regulation but also to the parent's ability to provide a more balanced and supportive environment. Similar improvements observed in the control group indicate that sensory integration therapy alone can also be effective. However, the inclusion of Floortime appeared to make these improvements more evident and holistic. The combined use of both methods offers a more comprehensive response to children's developmental needs and enhances therapeutic efficacy
Mixed convective flow of MHD tangent hyperbolic nanofluid over a radiative stretching sheet in porous media with chemical reaction
No full textThis work explores the mixed convective tangent hyperbolic nanofluid flow with magnetic field via radiative stretching sheet in a porous medium. While the flow problem is employed for non-Newtonian features, the Buongiorno nanofluid model is utilized for nanometer aspects that is, thermophoresis and Brownian motion. This model takes factors such as the heat source, chemical reaction effects, thermal conductivity, and for the porous medium uses Darcy-Forchheimer model. The nonlinear conservation equations of the partial differential are converted into nonlinear ordinary differential equations by appropriate transformations. To solve the evolving ordinary differential boundary value problem with suitable wall and free stream, an innovative numerical technique (Shooting Method) is applied. A rigorous parametric analysis is carried out to examine how various parameters affect the profiles of temperature, concentration, and velocity. Moreover, tables show the Sherwood and Nusselt numbers. More buoyancy ratio parameter causes the flow to slow, whereas improved mixed convection parameter raises the flow. The concentration profile falls as the Lewis number and chemical reaction parameter increase. The radiative parameter drastically raises temperatures. Concentration values decrease as the Brownian motion parameter increases. The study identifies uses for nanoparticles with specific properties in thermomagnetic processes
