Estudo morfológico do efeito do trauma mecânico sobre a amelogênese em incisivos de ratos
Authors: Neves Ilana Dantas , Aguiar Marcio Cajazeira 
Published: July 2019

<p><strong> </strong></p><p><strong>Introdução</strong>: A amelogênese compreende a formação do esmalte por células especializadas denominadas ameloblastos. Os ameloblastos secretam proteínas da matriz e são responsáveis pela criação de um ambiente extracelular que favorece a mineralização do esmalte. Contudo, diversos fatores, como o trauma dentário, podem interferir na amelogênese, contribuindo para a formação de um esmalte defeituoso. O trauma dentário tem sido responsável por muitos casos de hipoplasia que podem fragilizar o dente, além de trazer desconforto estético. <strong>Objetivo: </strong>Examinar as alterações morfológicas sobre o epitélio odontogênico e a matriz de esmalte de incisivos de ratos, produzidas por um trauma dentário. <strong>Metodologia: </strong>Incisivos de ratos foram extruídos e depois reposicionados em seus alvéolos originais. Decorridos 3, 7, 10, 20, 30 e 60 dias do procedimento cirúrgico, os dentes foram fixados em uma solução de formaldeído e glutaraldeído, processados histologicamente e corados com azul de toluidina. <strong>Resultados: </strong>A análise morfológica revelou a formação de uma matriz de esmalte bastante heterogênea, com espessura irregular, particularmente na porção mais apical dos incisivos. Algumas matrizes de esmalte expostas mostravam pequenas lacunas de reabsorção, muitas vezes com deposição de um material cementoide. <strong>Conclusão</strong>: O presente estudo mostrou que o trauma foi suficiente para produzir alterações hipoplásicas e de hipomineralização importantes no esmalte que se relacionaram com a fase funcional dos ameloblastos na região afetada. </p><p><strong> </strong></p>

AbstractThe fabrication of force sensors is reported using ZnO/ZnMgO coaxial nanorod arrays grown on a titanium (Ti) wire and their application for force monitoring inside a blood vessel during catheterization procedures. The core‐shell nanorod arrays are grown using catalyst‐free metal–organic chemical vapor deposition (MOCVD), enabling precise control over the growth and morphology of the nanorod arrays. The ZnO/ZnMgO heterostructures grown on Ti‐wires are characterized using various techniques and confirmed for suitability for force sensing applications. The force sensor is fabricated by creating Schottky metal contacts at the nanorod tips, while an insulating polyimide layer fills the gaps between the nanorod arrays, electrically separating the top metal contact from the bottom Ti‐wire. The sensor's performance is evaluated under various force conditions using a voice coil motor with a soft polydimethylsiloxane (PDMS) pressure stamp to mimic the contact force between the sensor and the blood vessel. The sensor demonstrated high sensitivity, stable, and fast force responses under periodic applied forces. Furthermore, the force sensor is integrated with catheter for contact force monitoring inside an artificial blood vessel. The fabrication of force sensor on a Ti‐wire substrate creates a flexible, biocompatible sensing element suitable for implantation and real‐time force monitoring in vascular environment.

AbstractTo advance the sustainable development of Li‐ion batteries, reducing the Co content in Li[NixCoy(Mn or Al)(1–x–y)]O2 has become essential, prompting the exploration of Co‐free Li[NixMn(1–x)]O2 alternatives. Among the promising solutions are Co‐free layered cathodes with compositional concentration gradients, which offer significant potential. However, their unique microstructure and compositional partitioning, key to their performance, are highly sensitive to synthesis temperatures. Over‐sintering can lead to the structural unpredictability of Co‐free cathode materials and detrimental effects on electrochemical properties. In this study, a highly stable Co‐free layered oxide cathode is developed by doping a concentration gradient Li[Ni0.9Mn0.1]O2, with high‐valence ions. This innovative strategy significantly reduces sensitivity to calcination temperatures, minimizing nano‐ and microstructural changes across a broad temperature range (750–810 °C). The particle‐level compositional gradation and grain‐level heteroelement encapsulation contribute to the cathode material's exceptional electrochemical performance. Mo doping, in trace amounts, plays a pivotal role in maintaining the stability of Co‐free cathodes, enabling the development of high‐potential (4.3 V vs graphite) Co‐free cathodes suitable for practical and sustainable Li‐ion battery applications.

Published: December 2024

AbstractSrNbO2N is a promising narrow‐bandgap semiconductor for sunlight‐driven water splitting but is generally subject to insufficient photocarrier separation and severe photocorrosion. Here, the targeted single‐crystalline SrNbO2N nanobelts are passivated by consecutive annealing in O2 and N2/NH4F to approach the right N/O ratio (1/2) and anion content (O + N = 60 at%). The passivation measures lead to both a low concentration (≈2.2 × 1015 cm−3) of defects including VO, Nb3+, Nb4+ for efficient photocarrier separation and unique fluorine‐rich, nitrogen‐poor surface with low surface energy for high stability against photocorrosion. Notably, the passivated SrNbO2N nanobelts deliver the highest values of photocurrent density of 4.5 mA cm−2 at 1.23 V versus RHE and stable photocatalytic (PC) Z‐scheme overall water splitting activity of ≈10 µmol h−1 H2 evolution under AM 1.5G illumination when used as photoanode materials for photoelectrochemical (PEC) water oxidation and the photocatalytic O2‐evolution moiety, respectively. These findings provide not only an effective guideline to upgrade the activity and stability of SrNbO2N but also fresh mechanistic insights into the role of passivation measures.
The velar chord and dynamic integration of the gular valve in crocodylians
Authors: Young Bruce A. , Cramberg Michael , Young Olivia G. 
Published: December 2024

AbstractCrocodylians evolved a unique gular valve that is capable of creating a water‐tight seal between the oral and pharyngeal cavities, allowing the animal to safely submerge with an open mouth. The gular valve has traditionally been described as consisting of two separate parts: an active mobile ventral portion (consisting of the tongue and portions of the hyolingual apparatus) and a dorsal portion, which is a static fold on the hard palate (often termed the palatal velum). The results of the present study argue that the two portions of the gular valve are functionally integrated, not separate, and that the dorsal portion (herein the dorsal gular fold) is a dynamic element the shape and tension of which are influenced by active and passive forces. Using gross dissection, histology, and DiceCT, the present study documents a previously underscribed component of the gular valve, the velar chord, which links the hyolingual apparatus to the dorsal gular fold, functionally integrating the two halves of the gular valve. Through endoscopic videography and a variety of manipulations on living crocodylians, this study demonstrates that changes in the tension on the velar chord directly alter the shape and tension of the dorsal gular fold. The shape changes observed in the dorsal gular fold could be accommodated by a shallow depression in the ventral surface of the palatine bones, herein termed the velar fossa. The velar fossa is a prominent feature of Alligator mississippiensis and was observed in other crocodilians; however, a survey of living and fossil crocodylians demonstrated that the velar fossa is not a universal feature in this clade. Understanding the functional linkage between the dorsal and ventral portions of the gular valve has implications beyond the dive reflex of crocodylians, since active manipulation of the dorsal gular fold likely plays a role in a variety of behavioral and physiological processes such as deglutition and vocalization.
Left–right difference in acetabular articular cartilage surface area and the quantification of acetabular fractures
Authors: Brueton Richard N. , Hughes Stephen W. 
Published: December 2024

AbstractX‐ray computer tomography scans were carried out on 11 female and 9 male dry bony pelvises. A 512 x 512 image matrix was used with a slice thickness and separation of 2 mm. Images were transferred onto a computer and the articular cartilage marked on each relevant image. The points were connected to form a triangle mesh and the total articular cartilage area calculated by summing the area of each triangle. There was a highly significant difference (p < 0.001) between the male and female acetabular areas, 25.4 ± 2.7 cm2 and 19.5 ± 2.0 cm2, respectively. The mean left–right difference was 0.2 ± 0.9 cm2 for males and—0.2 ± 0.47 cm2 for females. When the sign of the differences are removed, the mean and standard deviations of the differences is 0.5 ± 0.46 cm2 (2.3% ± 1.8%) for males and females, 0.66 ± 0.61 cm2 for males and 0.4 ± 0.27 cm2 for females. Each articular surface was outlined twice in order to assess the repeatability of the technique. The left–right variation in articular surface area was found to be similar to the variation in repeatability, suggesting that if any left–right difference does exist it is too small to be reliably detected by this technique. This enables the area of articular cartilage of the fragments of a fractured acetabulum to be compared directly with surface area of the contralateral intact acetabulum. Acetabular fractures can therefore be quantified by measurement of the articular surface area of the fracture components. Comparison with the clinical results will enable surface area to be developed as a prognostic factor in the management of acetabular fractures.

ABSTRACTRecent trends of rising temperatures and longer droughts between precipitation events are impacting water‐limited dryland ecosystems in the western United States. Although ecosystem drought response depends directly on soil moisture, trends in soil moisture (e.g., edaphic drought) remain more poorly explored than precipitation (e.g., meteorological drought), representing an important knowledge gap. Here, we applied the SOILWAT2 ecosystem water balance model to quantify long‐term trends of soil moisture and edaphic drought using observed daily weather from 1976 to 2019 at 337 stations across the western United States. We assessed edaphic drought for different plant community types (grass dominated vs. shrub dominated), and explored variations with soil depth and texture. The duration of the longest edaphic drought in a given year increased by 1.5 ± 0.2 days/decade for grassy and 1.7 ± 0.2 days/decade for woody vegetation. Importantly, these trends in edaphic drought were consistent with but greater in magnitude compared with meteorological drought indicating more severe water stress for both plants and ecosystems. The correlation between meteorological drought and edaphic drought was greater under woody vegetation (0.45) compared with grass (0.34) and greater at surface soil depths (0–20 cm; 0.46) compared with the deeper soil (20–100 cm; 0.34). Among soil textures, the correlation between meteorological and edaphic drought was highest on sandy soils and lowest on finer textured silty soils. Using the biogeographic domains (eight western NEON domains), we found that the Pacific Northwest, Pacific Southwest, and Desert Southwest exhibited the strongest increases in edaphic drought through time, but lower correlation between meteorological and edaphic droughts. These findings characterize strong but variable connections between edaphic drought and meteorological drought across the western United States and demonstrate the critical influences of vegetation type, soil depth, and soil properties in mediating the magnitude and spatial distribution of edaphic drought.

AbstractPhysicians' adherence to guideline‐recommended heart failure (HF) treatment remains suboptimal, especially regarding the target doses. In particular, there is evidence that non‐cardiologists are less compliant with HF guideline recommendations. This is likely to have a detrimental impact on patients' survival, readmissions and quality of life. Thus, the present document aims to address the reasons underlying low implementation and under‐dosing of guideline‐directed medical therapy in HF and to update a guidance for the initiation and rapid titration of HF drugs. In particular, aim of this document is to provide practical indications for drug implementation, to be applied not only by cardiologists but also by GPs and internal medicine doctors.

AbstractObjectiveCognitive behaviour therapy (CBT) online guided self‐help programs represent efficacious and accessible treatment options for adults with binge‐eating disorder (BED), but research on predictors of treatment outcome is scarce. This study aimed to investigate the predictive value of emotion regulation difficulties relative to that of negative mood on short‐ and longer‐term treatment outcomes in an online guided self‐help programme for BED above and beyond other predictors (age, sex, baseline BED severity).MethodsParticipants were 63 adults (87% female, mean age 37.2 years) with BED. Data was analysed using a hierarchical model approach.ResultsEmotion regulation difficulties better predicted both weekly binge‐eating frequency and eating disorder (ED) pathology at posttreatment than negative mood, after controlling for the effect of age, sex and baseline BED severity. At 6‐month follow‐up, neither emotion regulation difficulties nor negative mood further added to the prediction of weekly binge‐eating frequency, whereas negative mood, but not emotion regulation difficulties, did so for ED pathology.ConclusionThese findings indicate that emotion regulation difficulties at treatment begin might be a relevant predictor of immediate treatment outcome in online guided self‐help for adults with BED but might have lower impact on longer‐term treatment outcome than negative mood.Clinical trial register numberThe clinical trial register number is not given in this version of the manuscript due to anonymisation.

Published: December 2024

ABSTRACTThis study explores the factors affecting FinTech (Financial technology startups) equity financing and deals. Traditional and alternative financing are currently progressing together; however, alternative financing remains underexplored. Using panel data from 57 countries in 2010 to 2020 and one‐step difference generalised method of moments (Diff‐GMM) regressions, we show that, at the global level, gross domestic product (GDP), domestic credit to the private sector, regulations, innovations, globalisation, stock market return, information technology (ICT) goods export and internet users influence FinTech equity funding. With respect to FinTech deals, except GDP, regulations and globalisation, all other factors aforementioned have a substantial effect. Nevertheless, our category‐specific findings slightly differ from the global context. Our study emphasises the need for the rapid development of communication technology and increased accessibility to mobile internet services for users. Moreover, authorities should strike a balance between imposing regulations and facilitating FinTech equity funding growth. Innovations should prioritise user‐friendliness, affordability and commercial viability.
Transformation in the vernacular landscape of the Chatan weir irrigation area, China
Authors: Zhang Xukun , San Changjian , He Li 
Published: December 2024

AbstractOne of the most fascinating aspects of irrigation is the close connection between settlement networks and agricultural activities, with water infrastructure serving as the conduit. In particular, irrigation engineering serves as a testament to the evolution and development of local vernacular landscapes, exerting a profound influence on their formation. However, the contribution of irrigation to the development of the vernacular landscape and its internal interactions are poorly understood. This study aims to highlight the relationship between historical hydraulic systems and local landscapes, with a focus on the Chatan Weir Water Conservancy Project, an ancient irrigation engineering system in China. On the basis of archival records, historical materials and observations, this study constructed an analytical framework to analyse how the local landscape changed from 943 to the present. Specifically, this study delved into the evolution of water conservancy, farmland, settlement landscapes and their interactions in the Chatan weir irrigation area. The findings revealed that the local landscape of the Chatan weir irrigation area consists of a collection of landscapes created by residents through a bottom‐up approach. Furthermore, the water conservancy system has provided a stable water supply for both agricultural production and residential livelihoods, which has also shaped the spatial patterns of farmland and settlement landscapes. Finally, clan relations and rural management have played a vital role in the sustainability of the analysed irrigation system. The results of this study can provide insights into the sustainable coexistence of political and local landscapes.
Deconstructing imposter syndrome among BIPOC genetic counseling students: Insights from a longitudinal qualitative study
Authors: Carmichael Nikkola , Zayhowski Kimberly , Saenz Diaz Joselyn 
Published: December 2024

Abstract“Imposter syndrome” is a term used to describe feelings of pervasive self‐doubt despite evident success. It is the lay version of “imposter phenomenon,” a concept that was proposed as an explanation for why highly accomplished (mostly white and middle‐ to upper‐class) women persisted in believing that their success was due to luck or a mistake despite evidence to the contrary. However, the experience of imposter syndrome in genetic counseling, particularly among Black, Indigenous, and People of Color (BIPOC) individuals, remains underexplored. This study investigates the etiologies and impacts of imposter syndrome among BIPOC genetic counseling students with the aim of elucidating how the term is used and identifying potential interventions. We conducted semi‐structured interviews with 26 participants who were part of a longitudinal constructivist grounded theory study investigating the training experiences of BIPOC genetic counseling students. Using reflexive thematic analysis, we constructed themes related to self‐doubt, classroom and clinical performance, identity, and disclosing imposter syndrome feelings to others. Participants described imposter syndrome as arising from concerns that they were unprepared for their training program, less qualified than their peers, or admitted by accident or due to their BIPOC identity. Some participants attributed imposter syndrome to being a BIPOC student in a predominantly white profession. Comparisons to classmates and practicing genetic counselors, academic struggles, and anxiety about clinical rotations exacerbated imposter syndrome. Our findings underscore the multifaceted nature of imposter syndrome among BIPOC genetic counseling students and the need for a multipronged approach to mitigate its harmful effects. For BIPOC students, training programs should recognize that imposter syndrome is intertwined with racial inequities within the field that position them as imposters. We propose that supportive relationships with classmates, BIPOC mentors, and other BIPOC students can reduce imposter syndrome and enhance student well‐being and academic success.

AbstractBackgroundThe recycling or decomposition of plastic waste poses challenges due to its non‐organic nature. As a consequence of the unregulated production of plastic goods, a substantial quantity of plastic garbage has been generated. There is an increasing demand for sustainable substitutes for synthetic petrochemical‐derived plastic products. The utilization of cake molds made from plastic materials has become increasingly prevalent and they have become widely employed household items. Bio‐based bowls have the potential to serve as viable alternatives to their plastic counterparts. This study involved the fabrication of a bio‐based healthy edible bowl mold using natural ingredients, including multigrain flour, refined flour (maida), jaggery, flaxseed, and fenugreek essential oil. A nutrient‐rich edible bowl was developed by using different weight percentages (ranging from 0% to 10%) of wheat bran (WB).ResultThe addition of WB to the nutritious bowl resulted in the lowest levels of water absorption and oil absorption compared with the control group. The enhanced nutritional bowl demonstrated notable antioxidant activity. The inclusion of wheat bran resulted in a further enhancement of antioxidant action, with an approximate increase of 28% observed. The protein value of the nutritious bowl came to be 13.17 g/0.1 kg of protein. It was also revealed from an early soil degradation test that the bowl that was created exhibited biodegradability.ConclusionThe findings of this study offer a potentially viable method for developing a more sustainable substitute for cake molds/bowls made from plastic materials. © 2024 Society of Chemical Industry.
