Published: January 2025

In thermoelectrics, optimizing both carrier and phonon transport is crucial for enhancing thermoelectric performance. Strontium titanate, a representative N-type oxide thermoelectric material, often exhibits inferior figure of merit (zT ) due to its large band gap that limits carrier concentration, and high lattice thermal conductivity, attributed to strong Ti-O covalent bonds. Conventional approaches, such as aliovalent doping to increase carrier concentration or introducing structural defects to reduce lattice thermal conductivity, are insufficient as they fail to decouple the interdependent electrical and thermal properties. Herein, we introduce a high-pressure synthesis technique that concurrently modulates both the band gap and microstructure. This approach effectively enhances the carrier concentration by narrowing the band gap and increases the effective mass of the density of states through enhanced solubility limit of rare earth elements, significantly improving the power factor. Additionally, high-pressure condition induces microstructural defects, including point defects, dislocations, lattice distortions, and nanoscale grains, which promote broad-wavelength phonon scattering and minimize lattice thermal conductivity. Consequently, a peak zT value of 0.25 at 973 K is attained in high-entropy (Sr0.2La0.2Nd0.2Sm0.2Eu0.2)TiO3 synthesized at 5 GPa, representing a 5.3-fold improvement over undoped strontium titanate. This work highlights the pivotal role of high-pressure synthesis in decoupling the carrier and phonon transport in thermoelectrics.

El calentamiento global está generando importantes incrementos de la temperatura ambiental que está afectando a la calidad de vida de las personas. Hoy en día, el 30% de la población mundial reside en lugares que cuentan con condiciones climáticas de calor extremo y se espera que se incremente al 74% en las próximas dos décadas. En esta investigación se ha analizado la evolución que ha experimentado el índice de estrés por calor (Hi) entre los años 2008, 2012 y 2017 en las diferentes Zonas Climáticas Locales (ZCL) de la ciudad de Madrid mediante el modelo climático UrbClim de la Agencia Espacial Europea. Mediante imágenes satelitales Landsat 5 y 8 y para cada ZCL, se han tenido en cuenta las siguientes variables: Índice de vegetación de diferencia normalizada y el índice de edificación de diferencia normalizada. Nuestros resultados reportan que se ha producido entre los años un importante crecimiento de los valores de estrés por calor siendo mayor en las ZCL de uso urbano (ZCL-2, 3, 4, 5, 6, 8 y 9) y menor en las ZCL de uso rural (ZCL-A, B, C, D, E, F y G). Por tanto, es necesario el aumento de zonas y espacios verdes y el empleo de fachadas y cubiertas vegetales en las zonas urbanas al objeto de aumentar la resistencia al calor de las areas urbanas.

Background:

Periprosthetic joint infections (PJIs) are a major complication of total joint replacement surgeries. This study investigated the enhancement of mechanical properties and antibiotic release in ultra-high molecular weight polyethylene (UHMWPE) through the encapsulation of submicron gentamicin sulfate (GS) particles, addressing the critical need for improved implant materials in orthopaedic surgery, particularly in managing PJIs.

Methods:

The present study involved embedding submicron GS particles into UHMWPE flakes at concentrations of 2% to 10% by weight. These particles were prepared and blended with UHMWPE flakes using a dual asymmetric centrifugal mixer, and the blends were consolidated. The present study compared the mechanical properties and antibiotic release rate of UHMWPE containing submicron, medium (as-received), and large (resolidified) GS particles.

Results:

UHMWPE samples with submicron GS particles exhibited superior mechanical properties, including higher ultimate tensile and Izod impact strengths, compared with samples with larger particles. Additionally, the submicron GS UHMWPE blends demonstrated a markedly higher and more sustained antibiotic release rate.

Conclusions:

This study highlights the potential of incorporating submicron GS particles into UHMWPE to drastically improve the feasibility of using these therapeutic and functional spacer implants in expanded indications.

Clinical Relevance:

By offering improved mechanical strength and effective, prolonged antibiotic release, this innovative material could be used as a spacer implant to reduce the considerably high morbidity and mortality associated with PJIs. This material has the potential to prevent PJIs not only in high-risk revision cases but also in primary total joint arthroplasty procedures.

Published: January 2025

Focal Adhesion Kinase (FAK) is a key signaling molecule in focal adhesions (FAs) orchestrating the formation, maturation and turnover of the FA complex. A controlled FA lifecycle is essential for various cellular processes requiring mesenchymal cell migration and is harnessed by advanced cancers to initiate cancer invasion and metastasis. The mechanical force for migration is transmitted from actin stress fibers to FAs via specialized force transduction components in FAs. These forces are known to activate FA signaling, suggesting a communication between FA force transduction and FA signaling components, yet how this occurs mechanistically is unknown. Here we demonstrate that paxillin can act as an adaptor protein to connect FAK with the force transduction component vinculin. Our data show that this connection forms inefficient in the basal state but suggest Y925 phosphorylation in FAK as a key mechanism for optimal formation of the FAK:paxillin:vinculin linkage. This is achieved by switching binding of the paxillin LD2 motif from FAK to vinculin while keeping paxillin LD4 tethered to FAK. We further provide the first high-resolution crystal structure of LD2 bound to the vinculin tail domain, which importantly shows that vinculin can simultaneously link to actin. This therefore ensures an intact force transduction role of vinculin while tethered via paxillin to the signaling apparatus in FAs. With this data, all interactions of the force transmitting tether to FAK are structurally defined and we provide an atomic model for FAK force activation. In summary, we propose a phospho-regulated connection between signaling and force transduction components in FAs allowing for force induced activation of FA signaling.

Authors: Sezak Nurbanu , Korkmaz Ozge Eren , Arikan Burcu Acikalin , Kilic Osman Hasan Tahsin , Soydar Pelin
Published: January 2025

Background
Patients with chronic Hepatitis B (CHB) are more likely to experience mental health issues, which can become worse by liver fibrosis and inflammation. This study aimed to investigate the association of CHB-related necroinflammation and fibrosis on these psychiatric symptoms.
Methods
A cross-sectional analysis was conducted on 200 CHB patients. The degree of liver inflammation and fibrosis was evaluated using non-invasive (AAR, APRI, FIB-4, API) scores. Patients were asked to complete the HADS and FSS measures in order to gauge their psychological condition.
Results
In this study, 200 patients were examined. Anxiety was present in 6.5%, depression in 21%, and increased fatigue severity in 27%. AAR was significantly higher in patients with depression (p=0.008). FIB-4 score was significantly higher in those with anxiety (p=0.037) and showed a limited significant difference in fatigue (p=0.052). APRI values were significantly higher in the increased fatigue severity group (p=0.004). Multivariate analyses showed that liver fibrosis significantly increased the risk of depression (OR=2.35, p=0.036), and increasing age decreased the risk of depression (p=0.025). Significantly lower anxiety risk was associated with marriege (OR=0.06, p=<0.001). Patients on antiviral therapy had a 2-fold increase in fatigue severity (OR=2.07, p=0.027).
Conclusions
This study highlights the link between psychiatric symptoms and liver disease progression in CHB patients. The observed associations between liver fibrosis, depression, and fatigue underscore the importance of a holistic approach to CHB management that integrates mental health support. Such an approach may improve patient outcomes and overall quality of life.

Published: January 2025

Background
High rates of depression and anxiety have been reported in patients with fibromiyalgia (FM). Therefore, the aim of our study was to determine the volume of the amygdala, medial frontal cortex, limbic system and hippocampus in participants with anxiety and depression and to compare the fibromyalgia and control groups by determining the afferent and efferent fibers of the amygdala, which play an important role in anxiety and depression, which will be the first in the literature.
Methods
Only female subjects, 30 with fibromyalgia and 30 controls, were included in this study. Visual analog scale was used for pain sensation, BECK depression inventory, Hospital anxiety and depression scale were used for anxiety and depression. From brain diffusion MR images, tractography of the targeted pathway was calculated in DSI Studio software and the volume of targeted structures was calculated in VolBrain software program.
Results
The total volume of the medial frontal cortex, amygdala, limbic cortex and hippocampus was found to be statistically significant higher in the control group than in the fibromyalgia group (p < 0.05). It was also found statistically significant (p < 0.05) that the total number of fibers on the right side of the amygdala was higher in the patient group (13710.60 ± 4926.09) than in the control group (13099.14 ± 3677.12), but the number of fibers on the left side was higher in the control group (4057.37 ± 1388.57) than in the patient group (3552.70 ± 1493.35).
Conclusions
It is observed that depression and anxiety in fibromyalgia patients affect both white matter and gray matter volume in the central nervous system. Therefore, we believe that treatments on the central nervous system may be more effective in the treatment of anxiety and depression disorders in patients with fibromyalgia.

Published: January 2025

Background: The aim of this study was to investigate the relationship between minerals in domestic water and the incidence of rheumatoid arthritis (RA).
Methods: This longitudinal observational study included 434,958 British individuals from the United Kingdom. The study population consisted of RA-free participants with complete information on water minerals, genetic data, lifestyle habits, and physical measurements at baseline. The baseline assessment was conducted between 2006 and 2010, and the follow-up period was up to 2024. To assess individual genetic susceptibility, a polygenic risk score (PRS) of RA was calculated for each participant. Cox regression models were employed to examine the associations between water minerals, the PRS, and the occurrence of RA.
Results: A total of 5,880 new RA cases were reported during a median follow-up of 15 years. After controlling for multiple covariates, the concentration of calcium carbonate in domestic water was negatively associated with the risk of RA (hazard ratio [HR], 0.93; 95% confidence interval [CI], 0.90 to 0.95; p=1.74×10-9). Additionally, individuals in the highest tertile of the polygenic risk score (PRS) had a 53% to 74% increased risk of RA compared with those in the lowest tertile. Notably, individuals with a high PRS and soft water had a 92% (95% CI: 71% to 115%) increased risk of RA compared with those with a low PRS and very hard water.
Conclusions: The results suggest that exposure to soft water increases the risk of RA, especially in people who are genetically susceptible.

Published: January 2025

Hydrogen sulfide (H2S) is recognized as a critical gas signal molecule in the development and treatment of various diseases. Therefore, the development of a potent fluorescent probe for the detection of H2S is of great significance in biological systems. Herein, we synthesis of a new fluorescent probe, 3-(benzo[d]thiazol-2-yl)-2-(2,4-dinitrophenoxy)-5-methylbenzaldehyde (DPM-H2S) to detect H2S based on the recognition strategy that uses an ortho-aldehyde group to facilitate the thiolysis of dinitrophenyl ether, which results in its ultrafast response to H2S within 5 s together with a large Stokes shift of 106 nm. Under the excitation of 436 nm, after adding H2S to the probe, the fluorescence emission at 542 nm was greatly enhanced, and the fluorescence intensity was gradually strengthened with the increase of the amount of H2S, which had a good linear relationship with good limit of detection (LOD) of 4.9 µM. The probe DPM-H2S reacts with H2S to release its precursor 3-(benzo[d]thiazol-2-yl)-5-bromo-2-hydroxybenzaldehyde (DPM) and realizes the fluorescence “turn on” type response. Furthermore, the probe has been successfully applied for imaging hydrogen sulfide (H2S) in living HeLa cells. Additionally, the dual-side expansion strategy for regulating the optical features of traditional fluorophores could meet the increasing demands of sensing and imaging applications.

Published: January 2025

Introduction:
This study aimed to investigate the association and causality between central obesity and bone mineral density (BMD).
Methods
We utilized linkage disequilibrium score regression (LDSC) and Mendelian randomization (MR) to assess genetic correlations and causal relationships between waist circumference adjusted for BMI (WCadjBMI) and total body less head BMD (TB-BMD). Additionally, a cross-sectional analysis of 7,452 participants evaluated the relationship between A body shape index (ABSI) and TB-BMD using weighted multivariable linear regression and smooth curve fitting.
Results
LDSC and MR analysis confirmed a negative relationship between WCadjBMI and TB-BMD (β=-0.16; 95% CI: -0.26, -0.07). The cross-sectional study indicated that an increase of 0.01 ABSI corresponded to a decrease of 0.035 TB-BMD (g/cm2), with this negative effect being particularly pronounced in males and older adults. An inflection point was identified at ABSI = 0.076: below this threshold, ABSI positively correlated with pelvis BMD, whereas above it, the association became negative.
Conclusions
Central obesity is significantly negatively related to BMD. Maintaining ABSI within 0.058–0.078 is crucial for individuals in bone mass accrual (20–30 years) and stabilization (30–45 years) periods. In contrast, managing central obesity in people experiencing early bone loss (45–60 years) presents greater complexity and warrants further investigation.

Objectives
Globally, increasing numbers of people are living with multiple long-term conditions. When dementia is a co-occurring condition, contact with services is complicated due to the person’s cognitive difficulties and is often achieved as a dyad (person and carer). This realist review aimed to explain how dyads living with dementia alongside other long-term conditions are enabled (or not) to access and navigate health and care systems.
Method
An iterative, three stage approach synthesised evidence from empirical studies and stakeholders with lived and professional experience (ethics reference 23/LO/0829).
Results
Evidence from 61 studies and stakeholders (30 participants, 68 consulted) built and refined five programme theories for how health and care systems can achieve continuity of support, anticipate adverse events and maintain quality of life. Belief that concerns would be listened to and acted upon led dyads to seek assistance. Time and permission to discuss priorities, prognosis and acceptable levels of burden enabled uncertainties to be managed as a shared endeavour. The collective capacity of the dyad was enhanced by peer support, expertise they accrued over time and professionals who helped anticipate points of change.
Conclusion
Despite years of system changes, structural factors still create excessive burdens for dyads accessing services and constrain professionals’ ability to respond to complex needs.

Authors: Akpınar Muhammet Enes , Şenol Mümin Emre
Published: January 2025

Underground dam site selection is the process of selecting locations for dams constructed for the storage and management of groundwater to ensure the sustainable use of water resources. Underground dams store groundwater by utilizing underground aquifers, enabling more efficient and effective utilization of water resources. Particularly, the importance of underground dams has been observed to increase with global warming. They play a crucial role in various aspects, especially during periods of drought, in meeting agricultural irrigation and drinking water needs, among others. The construction of underground dams requires the simultaneous consideration of numerous criteria, thus turning the construction process into a decision-making problem. This decision problem is referred to in the literature as a multi-criteria decision-making (MCDM) problem. In this study, the site selection problem for a underground dam to be established in the province of Izmir has been addressed. In the problem at hand, there are five different alternatives consisting of districts within the province of Izmir and ten different criteria. These criteria and alternatives were determined by experts. In the study, the weights of the criteria were determined using the MAIRCA method, and the EDAS method was used for the selection of alternative locations. As a result of the study, Kınık district was identified as the most suitable alternative among the selected districts.

Authors: Atcı Duygu
Published: January 2025

Microelectromechanical systems (MEMS) are critical members of modern technological devices, due to their applications in various industrial fields. In the physical applications of MEMS, cracks are a common structural problem, affecting the static and dynamic behavior of the system. In this paper, the effects of cracks on microbeams with a tip mass under the influence of a magnetic field have been investigated. The micro-size effect of the beam has been involved into the model by using the modified couple stress theory. The crack has been modeled by using a torsional spring, with the spring coefficient corresponds to the severity of the crack. Thus, the beam has been modeled as consisting of two segments connected by a torsional spring. The equations of motion have been formulated using Hamilton’s principle. The obtained equations have been solved by using the method of multiple scales, a perturbation technique. Frequencies regarding both linear and nonlinear vibrations of the microbeams have been examined. The results obtained in this study have been validated by using available numerical results in the literature. The effects of parameters such as crack severity, crack location, tip mass and the magnetic field force on linear and nonlinear vibrations have been presented. The results indicate a significant decrease in the natural frequencies and nonlinear frequencies of microbeams with increasing crack severity.

Published: January 2025

The decrease in magnitude of maxillary dental anomalies at the primordial prevention level by using direct tracks, in addition to occlusal adjustments and masticatory guidance, has several features that can prove to be advantageous. The objective is to demonstrate how continuous in-person and online training performed by specialists in orthodontics and functional maxillary orthopedics of the Regional Hospital of Talca in the Maule region of Chile for odontologists in primary health care can be used to treat occlusopathy in its early stages. The cranial-cervical-mandibular system relies on genetic, environmental and functional factors for its development and the absence of functional stimuli can cause growth disturbances and malocclusions. The major advantage of Planas direct tracks is that it does not require patient collaboration because its basis is in selective wear and restoration with composite resin that acts continuously after construction. Additionally, it is low cost because sophisticated materials are not necessary for its execution and it is a simple technique that can be performed by general dentists, so it is not necessary to be a specialist in orthodontics.

Published: January 2025

Double-head machine tool has the advantages of high efficiency and high degree of automation. In order to reduce the weight of double-head machine tool and improve the stiffness of the entire machine. An optimization design method combining topology optimization, sensitivity analysis and adaptive multi-objective method is used. Firstly, simplify the model in SolidWorks and import it into ANSYS Workbench software to carry out finite element analysis on the entire double-head machine tool to find out the weak component as the beam. Afterwards, carry out topological optimization on the beam and redesign the beam structure, and complete the first optimization. Then, through sensitivity analysis of the input parameters, key parameters that significantly impact the objective function are identified. Subsequently, a multi-objective optimization function is constructed for these key parameters and the objective function. Finally, an adaptive multi-objective method is used to solve the problem and obtain a Pareto optimal solution set, completing the second optimization. The results show that the weight of the beam is reduced by 8.88 %, the deformation of the beam is reduced by 11.29 %, and the equivalent stress of the entire machine is reduced by 28.33 %. This design not only yields significant economic benefits but also serves as a valuable reference for the lightweight design of large machine tool crossbeams.
Urbanization-informed, uncertainty-based calibration approach for simulating the impact of urbanization on flooding in a data-limited region
Authors: Nithila Devi N. , Kuiry Soumendra Nath
Published: January 2025

Rapid urbanization necessitates reliable assessments of its impact on flooding. The two major challenges in data-sparse basins are the equifinality of the hydrological parameters and their dynamic updating with respect to changing land use and land cover. Existing calibration approaches typically address only one of these challenges. The existing approaches that allow for dynamic updating of parameters with changing land use and account for parametric uncertainty are referred to as Dyn_CN and uStat_CN, respectively. We propose a novel ‘urbanization-informed uncertainty-based calibration approach’, referred to as uDyn_CN, that combines the advantages of both these approaches. The existing and proposed calibration approaches were applied to India's data-limited, frequently flooded, urbanizing Adyar river basin comprising Chennai city. The performance assessment of the methodologies was done in an externally coupled hydrological-hydraulic modelling framework. In that light, the proposed hydrological calibration approach is more accurate than the existing approaches in both the hydrological and hydraulic simulations. For instance, the RMSE values for the simulated maximum water depths for uDyn_CN, uStat_CN, and Dyn_CN approaches are 0.22, 0.36, and 0.6 m, respectively. The study also demonstrates its subsequent application to analyze the impact of urbanization on flood hazard in the Adyar basin by 2050.

One of the most costly stages of activated sludge wastewater treatment plants is the treatment and dewatering of waste sludge. Chemical conditioning of sludge, as one of the most widespread methods to enhance sludge dewaterability, accounts for a significant portion of operational expenses due to the consumption of expensive polymeric compounds. This research aims to assess the cost-effectiveness of ochre soil, modified with hydrochloric acid, as an affordable mineral for conditioning waste sludge in an activated sludge system. The optimal conditions for acid modifications are obtained using response surface methodology. Then, its performance is compared with conventional coagulants (ferric chloride and alum) and in combination with cationic polyacrylamide (CPAM). To assess the conditioning process efficiency, the specific resistance to filtration (SRF) parameter was employed. At an optimal dose of modified ochre soil (MOS) equal to 300 (mg/g dry solids), the SRF value decreased from 31.96 to 2.7 Tm/kg. The combination of 100 (mg/gDS) MOS with 0.5 (mg/gDS) CPAM showed as the most cost-effective among the coagulants tested, with a 31% greater SRF reduction compared to CPAM used alone. This study shows the practical efficacy of an eco-friendly natural mineral as a polymer alternative, with the potential for sludge dewatering.

Published: January 2025

This study explores the dynamics of investor behavior in the context of Peer-to-Business (P2B) crowdlending, focusing on how investor experience influences their investment intensity and risk assumption. Utilizing data from the Spanish P2B lending platform MytripleA, the research analyzes the investment patterns of 1340 private investors across 798 loans. The study investigates the relationship between the length of investors' experience and their propensity to fund a larger number of projects and to undertake higher risk investments. It addresses key hypotheses that posit a positive correlation between investor experience and the decision to increase investment intensity and risk level. The methodology integrates a robust Partial Least Squares (PLS) structural equation modeling to validate the proposed relationships. Results indicate that experienced investors tend to diversify their investment portfolios by engaging in riskier projects, confirming the hypothesized positive relationships. These findings contribute to the understanding of investor behavior in crowdlending, offering insights for platform operators and potential investors regarding investment strategies and risk management. The study also highlights the importance of investor experience in influencing investment decisions, underlining its role in the dynamic and evolving landscape of crowdlending.

Percepção dos impactos socioeconômicos e ambientais dos parques eólicos em áreas agrícolas: estudo de caso do município de Serra do Mel-RN
Authors:   , Sobrinho Júnior Manoel Fortunato
Published: January 2025

Em virtude da degradação do meio ambiente e do esgotamento dos recursos naturais,
atualmente muitas nações buscam a autossuficiência em produção de energia e a diversificação
da sua matriz energética, sendo as energias renováveis fundamentais nesse processo. Desta
forma, a energia eólica por sua qualidade ambiental e por sua abundância em muitos lugares do
mundo vem sendo bastante utilizada. A região Nordeste do Brasil apresenta um elevado
potencial para a implantação de parques eólicos, principalmente na área do litoral, entretanto
nos últimos anos alguns empreendimentos se voltaram para locais onde se pratica a
agropecuária provocando impactos para as famílias camponesas, fazendo-se necessário uma
análise sobre esses impactos principalmente em áreas agrícolas da região semiárida. Neste
contexto, o presente trabalho tem como objetivo analisar os impactos socioeconômicos e
ambientais da implantação de parques eólicos em áreas agrícolas. A pesquisa foi realizada no
município de Serra do Mel, maior produtor de caju e também o maior em capacidade outorgada
de energia eólica do Estado do Rio Grande do Norte. Os métodos utilizados foram a realização
de entrevistas semiestruturadas com os agricultores locais, coleta de dados secundários em
orgãos oficiais e a identificação das mudanças ocorridas na região no período de 2014 a 2019
através de imagens de satélite, perfazendo uma série temporal das alterações no uso e ocupação
do solo. Os resultados obtidos nas entrevistas e nas áreas de levantamento foram processados
no sistema de informações geográficas QGIS e demonstrados através de mapas, gráficos e
tabelas. O estudo concluiu que a população convive sem maiores problemas e sem conflitos
aparentes com o empreendimento eólico. Do ponto de vista econômico a iniciativa tem sido
benéfica para o município de Serra do Mel, com geração de emprego e renda e melhoria da
qualidade de vida. Do ponto de vista social, são poucos os transtornos causados pela atividade
eólica e também são poucas as ações sociais realizadas pelas empresas envolvidas para
benefício da comunidade. Foi possível observar que os principais impactos ambientais
decorrentes da implantação dos parques eólicos até o presente momento causaram poucos
prejuízos nas atividades, nas propriedades e na vida dos agricultores e os mesmos se mostraram
otimistas em relação a viabilidade e conciliação do empreendimento com a atividade agrícola.
Constatou-se também que o uso e ocupação do solo do município de Serra do Mel não foi
significativamente afetado com a implantação dos parques eólicos.
Estudo genômico e proteômico do fitopatógeno Alternaria alternata na cultura do mamão
Authors:   , Brito Anna Luisa de Carvalho
Published: January 2025

O Brasil é o segundo maior produtor e terceiro maior exportador mundial de mamão. O
cultivo intensivo de mamoeiros em áreas fixas tem favorecido doenças fúngicas capazes de
causar perdas no campo e também no período pós-colheita. Lesões foliares de origem fúngica
prejudicam a capacidade fotossintética da planta podendo levá-la a morte, além de facilitar a
invasão no fruto de patógenos causadores de podridão durante o amadurecimento, sendo
responsáveis pelas perdas mais severas. Na cultura do mamão, a Alternaria alternata é capaz
de causar danos tanto no fruto como também na folha. O objetivo do presente trabalho foi
estabelecer um diagnóstico rápido e sensível da infecção de A. alternata na cultura do mamão,
e investigar proteínas relacionadas a tal infecção. No presente estudo, primers gene
específicos baseados na sequência do gene Al a 1 (AaltDAlta1 – CGCATCCTGCCCTGTCA/
AinfIAlta1 - GTTGGTAGCCTTGATGTTGAAGC), foram utilizados para se fazer o
diagnóstico molecular rápido e seguro da infecção de A. alternata em áreas produtoras do Rio
Grande do Norte. Além da análise genômica, análise proteômica baseada em SDS-PAGE foi
utilizada para separar proteínas extraídas de grupos controle e inoculado de mudas de mamão
das variedades Tainung e Feltrin, a fim de investigar proteínas diferencialmente expressas
com potencial de interferir no processo de estabelecimento da patologia. Os resultados da
análise genômica mostraram que em 100% das áreas produtoras analisadas, foi encontrada a
presença do fungo A. alternata, infectando mamoeiros no estado do Rio Grande do Norte. Na
avaliação dos sintomas após inoculação, foi percebido que a variedade Feltrin possivelmente
apresenta uma maior resistência à infecção, por ter apresentado sintomas mais brandos. Com
as avaliações proteômicas, foi visto que na variedade Tainung as mudas inoculadas com A.
alternata apresentaram redução do conteúdo proteico expresso. Dentre as proteínas inibidas,
identificou-se a proteína RuBisCo, envolvida no metabolismo fotossintético vegetal. Assim,
sugere-se que a inibição da proteína Rubisco possa estar envolvida nos mecanismos que
levam ao surgimento dos sintomas relacionados a patogenia.
Aplicação de coberturas comestíveis a base de fécula de mandioca, cera de abelha e extrato de romã na conservação de queijo tipo coalho
Authors:   , Freire Bárbara Camila Firmino
Published: January 2025

O queijo de coalho é um produto lácteo com elevada expressão no Nordeste brasileiro, onde é amplamente produzido e consumido. No entanto, as características inerentes deste produto, bem como a falta de padronização na produção, tendem a comprometer a sua qualidade e segurança. Assim, métodos de conservação se fazem necessários para manutenção de sua qualidade, existindo, atualmente, nesta área de pesquisa, uma maior busca por alternativas naturais. Como exemplo, tem-se então a utilização de coberturas comestíveis obtidas pela exploração de biopolímeros e compostos bioativos. Dessa forma, o seguinte estudo teve por objetivo, produzir uma cobertura comestível a base de fécula de mandioca, cera de abelha e extrato de romã e avaliar a sua eficiência na qualidade de queijo tipo coalho. Inicialmente foram produzidos diferentes tipos de filmes e coberturas para caracterização das propriedades e aplicação nas peças de queijo, respectivamente. Os filmes não apresentaram diferenças entre os tratamentos, exceto na cor, microestrutura e propriedades mecânicas, sendo o filme adicionado de extrato de romã e cera de abelha mais resistente à quebra e flexível. Após produção do queijo e aplicação das coberturas, realizou-se então a análise sensorial, demonstrando uma boa aceitação por parte dos provadores. Na avaliação da qualidade e vida útil, as amostras estocadas sob refrigeração (7±1°C) ao longo de 15 dias obtiveram resultados satisfatórios na redução de deteriorantes, principalmente sobre bactérias aeróbias mesófilas em todos os tratamentos. Na físico-química, as coberturas reduziram a acidez das amostras, mantendo-se estatisticamente relevante até o nono dia de análise e sem interferir na coloração dos queijos. A partir dos dados obtidos, conclui-se que as coberturas naturais surgem como uma alternativa na conservação do queijo tipo coalho, sendo os melhores resultados observados pela utilização da cobertura de fécula de mandioca, extrato de romã e cera de abelha.
