Authors: Li Yudie , Wang Dongqing , Fang Bo , Cao Jialun , Shen Jiayi , Han Xiaoyang
Published: December 2024

For the enrichment of photosensitive micelle systems, several novel types of UV light viscoelastic photosensitive micelle systems were prepared by compounding oleamidopropyl dimethylamine (PKO–O) and trans-o-methoxy-cinnamic acid (trans-OMCA). The flow curves and viscoelastic properties of the micelle systems were investigated before and after UV irradiation at a wavelength of 365 nm. The concentration of PKO–O was controlled at 1.0 wt% and 2.0 wt%, with a fixed molar ratio (MR) of PKO–O to trans-OMCA of 1:0.75, after exposure to UV light, the zero shear viscosity (η
0) of the optimal micellar system decreased by more than 99 %. Furthermore, when the mass concentration of PKO–O ranged from 3.0 wt% to 5.0 wt%, while maintaining the same molar ratio, the optimal micelle system achieved a more than 15-fold increase in η

0
. These phenomena are attributed to the isomerization of trans-OMCA to cis-OMCA under UV light irradiation. The Carreau-Yasuda model effectively describes the flow curves of the PKO–O/OMCA micelle systems. The viscoelastic response of the micelle systems can be well characterized by the Maxwell model. Furthermore, the four-parameter rheokinetic model was used to accurately describe the variation of η

0
with UV light exposure time. This study promises to explain the irreversible photosensitive thickening and thinning of tertiary amine viscoelastic micellar systems, while also providing valuable rheological references.
State-dependent gas chromatography based on flexible and tunable porous coordination polymers
Authors: Mertens Florian O.
Published: December 2024

Gas chromatography can be based on very different types of stationary phase materials such as porous crystalline, polymeric or even liquid materials. These materials are not supposed to change significantly when brought into contact with the analytes to be investigated. Analytes may overload the stationary phase which changes the interaction between analyte and stationary phase causing often tailing or fronting in the detected peaks. In contrast to these unintended effects, new materials such as flexible porous crystalline coordination polymers can be utilized as stationary phase allowing the crystal structure to undergo transformation induced by the analytes. Depending on the analyte concentration, even a complete collaps of the porous structure can be achieved. The generic theoretical investigation presented will address the possible effects caused by state-dependent transformations of stationary phases. A first experimental realization of such a system with a well-known metal-organic framework (MOF) demonstrating unconventional chromatographic behavior was also generated and investigated.
Modos de viver e normalização em uma sociedade de projetos
Authors: Hecktheuer Luiz Felipe Alcantara
Published: December 2024

Partindo do diagnóstico de que possamos estar vivendo em uma sociedade de projetos e apoiados em noções como, o diagnóstico do presente e a dobradinha biopolítica/biopoder (Michel Foucault), neste texto, são problematizados os projetos sociais esportivos (PSE) naquilo que mantêm de implicação com estratégias para intervir no seu público alvo. Tal diagnóstico, proveniente de pesquisa acerca desses projetos que se proliferam por toda sociedade, desenvolve-se em torno da tese de que seriam sempre a outros modos de viver que tais projetos visam. Deste investimento de pesquisa resultou a identificação da invenção de uma população e da inclusão “social” como estratégias para contrapor à vida e aos modos de viver existentes, outros, esperados e desejados, caracterizando certa não aceitabilidade que remete a modos de viver indignos de serem vividos.

Citrus are a horticultural commodity that has high economic value and tends to be liked by many people. In the Bawen area, Semarang Regency, there is a plantation that cultivates various types of orange plants. Many citrus plants have signs of pest attacks that have not yet been identified. This research aims to obtain data related to insect diversity and the level of damage caused by insect pest attacks on citrus plants. This research is an exploratory type of research, using a survey method. The research location was determined using purposive sampling by taking three fields of Siam Honey, Sumowono and Pamello oranges. Insect sampling was carried out using pitfall trap, yellow trap, direct observation and interviews. The results of the study showed that the diversity index was H' = 3.3, honey siam = 3.3, pamello orange (H' = 3.1) and sumowono siam (H' = 2.9). The similarity value of the three types of orange is 0.8 and the dominance is 0.05 (honey siamese), 0.06 (pamello) and 0.07 (sumowono). At the time of research, orange plants were in the generative phase so they could attract more insects. The level of damage due to pest attacks is classified as moderate. The conclusion of this research is that the highest species diversity value is Siam Honey, then Pamello orange and Siam Sumowono, the presence of insects is evenly distributed and no one species dominates. The benefit of this research is to obtain information regarding the diversity of insect types and the level of damage caused by insect pest attacks.

In brief

Because the study of endometrial stem or progenitor cells has focused more on their potential ability to repair the endometrium, it is necessary to investigate their role in preparing the tissue for embryo implantation. Therefore, we selected CD90 protein as a marker of the population of cells with progenitor properties to study their contribution to hormone-regulated endometrial processes.

The endometrium is a dynamic tissue that undergoes significant changes during the reproductive cycle and pregnancy. Its high regenerative capacity is because of the presence of progenitor cells, which maintain tissue homeostasis. Previous studies have identified small populations of endometrial progenitor cells and investigated their role in tissue repair. However, the involvement of these cells in hormone-mediated changes in the endometrial stroma during decidualization and implantation has not been fully understood. In this study, we used CD90 as a potential marker for endometrial progenitor cells. We demonstrated that CD90+ cells have a higher clonogenicity and lower proliferative potential than CD90−. The localization of this marker around the embryo during decidualization led us to hypothesize that CD90+ cells may be directly involved in preparing the endometrial stroma for implantation. The results demonstrated an increase in the percentage of CD90+ cells in the endometrium of pregnant mice compared with nonpregnant mice. Additionally, the embryos exhibited a greater ability to spread on CD90+ cells in vitro. Our data support the hypothesis that CD90+ cells play a functional role in implantation, although the exact hormone-dependent mechanisms require further investigation. Based on the subluminal localization of CD90+ cells, we suggested that the luminal epithelium maintains a CD90+ cell surface phenotype. Consequently, we established epithelial–mesenchymal organoids, and the localization of CD90 in these organoids resembled that observed in vivo. Overall, CD90+ cells demonstrate high clonogenicity and contribute to the preparation of the stroma for interaction with the embryo during the implantation process.
Change of the Optoelectronic Properties of Semiconductor Compounds Induced by Nanosecond Laser Irradiation Pulses
Authors: Levytskyi S. , Cao Z. , Koba О. , Koba М.
Published: December 2024

New research has discovered discrepancies in the melting points, plasma generation, and resulting changes in optoelectronic properties of semiconductor materials A2B6 and A3B5 when exposed to laser light, even when the experimental conditions are the same. Therefore, accurately determining the thresholds at which these complex semiconductor compounds melt and create plasma remains an unsolved task. This work utilizes nanosecond ruby laser irradiation to thoroughly examine fundamental characteristics of semiconductor compounds A2B6 and A3B5 when exposed to laser irradiation. This includes investigating the thresholds at which melting occurs, the production of plasma, and any changes in optoelectronic capabilities. The experimental results demonstrate notable discrepancies in the melting points and optoelectronic characteristics of various semiconductor materials when subjected to the same experimental conditions. The variations mostly arise from inherent statistical biases in the parameters of the sample. By employing photoacoustic and photoconductive techniques, we accurately ascertained the melting points of cadmium telluride, gallium arsenide, and aluminum gallium arsenide crystals, providing exact empirical data on the characteristics of these corresponding substances.
In addition, we performed photoconductive spectroscopy tests on cadmium telluride exposed to nanosecond ruby laser pulses. We noticed a significant impact of the creation of a tellurium layer on the photoconductivity. The investigations showed that the existence of a tellurium layer results in photoconductivity that varies depending on the spectrum, with the most significant improvement observed in the short-wavelength region.
Mujeres silenciadas por la historia. La visión de Rosa Montero y Cristina Fernández Cubas
Authors: Russo Lucia
Published: December 2024

Este estudio tiene la intención de demostrar cómo Rosa Montero y Cristina Fernández Cubas, en momentos determinados de su trayectoria narrativa abordan un tema que a finales del siglo pasado se convierte en objeto de investigación de los Estudios de género para luego consolidarse en el siglo XXI dentro del ámbito académico: dar a conocer a mujeres ilustres que han influido en distintos sectores del saber a lo largo de la historia y cuya importancia ha sido infravalorada por el canon tradicional hasta los años ochenta y noventa. Del análisis comparativo realizado, se puede concluir que ambas autoras abandonan el canon tradicional. De hecho, Montero y Fernández Cubas relatan la historia y la personalidad de estas mujeres recurriendo a medios literarios más tradicionales como la biografía, la novela o el ensayo que recrean a través de una visión y un estilo propio, hasta otros más novedosos y de mayor difusión como los programas de televisión.
Aproximación a los fundamentos de la invención retórica y la cosmovisión en el Romanticismo
Authors: Baena Criado Jesús Manuel
Published: December 2024

Los fundamentos, presupuestos y posibilidades de la cosmovisión en la Modernidad y, en particular, en el Romanticismo, conciben la creación ya no como el desvelamiento de lo Uno, la indagación sobre lo divino y lo Verdadero, sino que el poeta lo es en su condición de ser humano y a partir de su propia humanidad en el mundo. Es así que la fractura que se produce de forma paulatina con la cosmovisión cristiana dota al concepto de creación de una autoridad e imperio de los que carecía, y que son a su vez consustanciales al reconocimiento y emancipación de la individualidad en la afirmación de sí misma. De esta forma, el concepto de la invención deja de comprenderse como mímesis, en los términos en los que hemos tratado con anterioridad, para dotarse de una significación plena, ofreciendo una nueva concepción de la poesía y del poeta que completa su sentido teórico original. En este trabajo nos proponemos realizar unas aproximaciones a los fundamentos de la creación, comprendida desde la invención, y la cosmovisión en el Romanticismo.

Authors: MUSHII О. , PAVLOVA А. , BAZAS V. , ZADVORNYI T. , LUKIANOVA N.
Published: December 2024

Background. The development of breast cancer (BCa) is largely determined by the characteristics of the tumor microenvironment (ТМЕ), which undergoes significant changes during the progression of the disease. Mast cells (MCs) are among the least studied components of the TME. The aim of the work was to investigate the relationship between the density of infiltration and the functional activity of MCs with indicators of osteopontin (OP) expression in BCa tissue. Materials and Methods. The study was conducted on the postoperative material of 15 patients with fibroadenoma and 78 patients with stage I—II BCa. MCs in the tissue of benign and malignant breast tumors were detected by a histochemical method using toluidine blue. The functional activity of MCs was calculated by the degranulation index. The OP expression in tumor tissue was assessed by the immunohistochemical method. Results. The density of MCs infiltration and their functional activity are associated with such indicators of BCa malignancy as tumor size, lymph node involvement, tumor grade, molecular subtype, proliferative activity, and PR- and HER2/neu-expression status. A high expression of OP in the stromal component of BCa is associated with the growth of the tumoral MCs population, metastatic lesions in regional lymph nodes, and a low differentiation grade of the tumors. In addition, OP is involved in the regulation of MCs in the tissue of the luminal B and basal molecular BCa subtypes. The level of OP expression in the parenchymal component of BCa is associated with the number of infiltrated MCs in the presence of metastatic lesions of regional lymph nodes. Conclusions. The identified relationship of OP expression level with the topology and functional activity of MCs in BCa tissue, depending on the clinical status of patients, indicates the prospects for their use in predicting the aggressiveness of the tumor process.

Authors: STEPANOV Yu. , KOLESNIK D. , YAKSHIBAEVA Yu. , SOLYANIK G.
Published: December 2024

Background. The ability to metabolic reprogramming is a distinctive feature of metastatically active tumor cells. A classic example of metabolic reprogramming, characteristic of almost all malignant cells, is aerobic glycolysis. Therefore, inhibition of glycolysis in tumor cells is considered a promising strategy for antitumor therapy. Aim. To generate Lewis lung carcinoma (LLC) cell subpopulation after pretreatment by a lactate dehydrogenase (LDH) inhibitor — oxamate in adhesive growth conditions, and then to study the metabolism of this subpopulation in the anchorage-independent growth conditions. Materials and Methods. LLC cells were cultured without oxamate or with 17 mM oxamate in the adhesive growth conditions with the following transition to the anchorage-independent growth conditions without oxamate. A distribution of LLC cells by cell cycle phases, apoptosis rate, levels of reactive oxygen species (ROS), E-cadherin, and vimentin were determined by flow cytometry. Glucose consumption and lactate production were determined by spectrophotometry. Results. 48-h oxamate treatment in adhesive growth conditions resulted in a 30% decrease of the total number of LLC cells compared to the control. In 72 h after the transfer of both oxamate-treated and control cells into the anchorage-independent growth condition without oxamate, the number of viable cells pretreated with oxamate was reduced by 17% (p < 0.05) compared to the control cells. However, the distribution of cells by cell cycle phases did not differ. In cells pre-treated with oxamate, the rate of glucose consumption decreased by 20% (p < 0.05), ROS generation was reduced by 17%, vimentin expression decreased by 10% while the rate of lactate production was the same in oxamate-pretreated and control cells. Conclusion. The cytostatic effect of oxamate demonstrated in adhesive growth conditions persisted for 72 h in the anchorage-independent growth conditions. The absence of differences in the cell cycle phase distribution and a decrease in the ROS generation may indicate the initial stage of overcoming the cytostatic effect of oxamate after 72 h of culturing LLC cells in anchorage- independent growth conditions.
Information structure in Nda'nda'
Authors: Gueche Fotso Hugues Carlos
Published: December 2024

This paper describes how a syntactic constituent can be manipulated within the structure of a sentence in Nda’nda’ in order to give it pragmatic prominence. To achieve this, attention has to be paid to the various means used by Nda’nda’ speakers to bring listeners to focus their attention on the constituent bearing the special information they want to pass across. Two main categories of prominence in information structure are usually differentiated in language generally: topic and focus. Focus in Nda’nda’ is encoded by cleft constructions, pseudo-cleft constructions and the adverbial ndɑ̀ʔ ‘only’. While analyzing focus via cleft construction we argue that there is similarity between the object cleft construction and the relative clause. The focus marker ndaʔ marks restrictive focus with concomitant morphosyntactic changes. Topic constructions are restricted to noun phrases and are achieved essentially through left-dislocation to mark contrastive topic with an additional pronoun in resumptive function whose form varies depending on whether the topicalized element is human or non-human.
Numeral mutation and ablaut in Lower Fungom languages
Authors: Tschonghongei Nelson C. , Good Jeff
Published: December 2024

This paper provides new information on patterns of consonant mutation and vowel ablaut found in the numeral systems of four language varieties of the Lower Fungom region of Cameroon. This phenomenon is of interest in the context of the comparative investigation of noun class marking in Niger-Congo languages, and a particularly noteworthy pattern found in some of the varieties are apparent cases of mutated numeral roots being analogically extended to contexts where they would not be predicted to be found on the basis of regular patterns of sound change.
Whose rights? Which representation?
Authors: Tattay Szilárd
Published: December 2024

The legal conceptualisation of upcoming generations and their specific rights raises important theoretical issues and constitutes a special challenge to jurisprudence in general and legal philosophy in particular. Not even the most essential questions regarding the legal situation of unborn generations have been settled yet. Are future generations capable of being holders of rights? And if so, how can we conceptualise their rights? Can we use the conventional rights theories for that purpose? What does it mean and how is it possible to ‘represent’ the rights or interests of future generations? What kind of rights or interests can be attributed at all to not-yet-existing people? Can we identify the interests of future generations, and if so, how can we specify them? In this paper I will endeavour to address the questions raised above and make an attempt to offer an adequate conceptual framework for their analysis by merging two quite distinct theoretical discourses which are seldom combined: the legal theoretical discourse on the nature, scope and holders of rights, and the moral philosophical branch of the multifaceted discourse on intergenerational justice.
The Role of Parents in Preventing Children's Gadget Game Addiction Through Child-Friendly Sports
Authors: Kustanti Dewi , Nurlinah Nurlinah
Published: December 2024

Gadget addiction in children is a growing concern in the digital age, negatively impacting their physical, social, emotional, and academic development. Parents play a vital role in preventing this addiction by understanding their children's developmental needs and guiding them toward healthier activities. Engaging children in sports can effectively reduce gadget dependency, as studies indicate that excessive screen time decreases physical activity. Parental involvement is essential, particularly as mothers often take a more active role in their children's lives. This study utilizes parental guidance and a literature review to explore the importance of parental education in promoting balanced gadget use. Ultimately, the findings highlight that parents are crucial in shaping their children's personalities and fostering positive habits for healthy development.
Contribution: The findings underscore the necessity for targeted interventions that empower parents, particularly mothers, to take an active role in shaping their children's behaviors and promoting a balanced lifestyle in an increasingly digital world.
Statistical properties of English text produced by Korean and Chinese authors
Authors: Nelson Robert
Published: December 2024

This article presents findings from a comparison of the Zipf’s law and Heaps’ law properties of English texts produced by second language writers of English to similar texts produced by native writers. Zipf’s law is a famous statistical law capturing the distribution of words in texts, while Heaps’ law describes the rate at which new words are encountered as one reads a text. The analysis of the Zipf properties of texts by writers whose first language (L1) is Korean shows that the distribution of words and multiword sequences (n-grams) is different from that observed in native speakers’ texts. These differences imply that Korean writers do not fully exploit English pronominals. Analyses also indicate that the Heaps’ law properties of texts produced by the L1 and L2 writers show different rates of lexical innovation. A number of studies have estimated the Zipf’s and Heaps’ properties of native language texts in various contexts (e.g., Li, 1992; Cancho, 2005), while others have considered the consequences of Zipf’s law for second language acquisition (Laufer and Nation, 1995; Meara, 2005; Ellis, 2012). This study is the first attempt to estimate the parameters of these laws for texts produced by different populations of the second language writers.
Brassinosteroids: an alternative to vine cultivation to enhance drought tolerance, in semiarid land at Chihuahua, Mexico

Chihuahua is an internationally recognized state for its quality in the production of vines (Vitis vinifera), and wines. However, it is exposed to drought events and has presented economic and social problems due to the low availability of fresh water. The aquifers destined for intensive agriculture, such as Cuauhtémoc present the most pronounced deficit and they have been operating with deficits of −197 mm3 year-1. Chihuahua typically receives an average annual rainfall of 224.5 mm. These semiarid ecosystems, with water scarcity, are not suitable for viticulture unless supplementary irrigation is available. One alternative option is to apply brassinosteroids to enhance the response of antioxidant systems under drought stress. Although growers in Chihuahua use auxins, cytokinins, and gibberellins as enhancers in the vine crop, the application of brassinosteroids (BRs) is not yet used, because there is poorly knowledge about their role and its activity involved in the yield and quality components of the vines and their antioxidant capacity. The brassinosteroids are successfully used to increase production, the size and weight of bunches and berries, to improve the color of grapes, to extend their postharvest life, and to increase the tolerance of plants to abiotic stress, specifically drought. Therefore, this review collects, analyses, and summarizes recently published information and highlights the importance of the properties of brassinosteroids as an antioxidant response in metabolism, fruit production, and quality, their postharvest action in vine cultivation, and recommends their safety use for grape-growing areas in Chihuahua, Mexico, and regions in the world that suffer from drought.

Published: December 2024

The fall armyworm (Spodoptera frugiperda) is a major pest of several crops leading to significant yield losses. Developing effective and eco-friendly pest management strategies against fall armyworm (FAW) is crucial for sustainable agriculture. This study investigates the synthesis and evaluation of the insecticidal activity of silver nanoparticles based on an aqueous extract of Moringa oleifera leaves (MOL-AgNPs) against FAW. The synthesized MOL-AgNPs were characterized and confirmed using UV-Vis spectroscopy, Energy Dispersive X-ray Spectroscopy (EDX), Fourier Transform Infrared (FTIR), and Scanning Electron Microscopy (SEM) imaging. Four concentrations (200, 300, 400, and 500 ppm) of MOL-AgNPs and a deionized water as blank control were tested against larval mortality of the last three larval instars of FAW by food dipping method. Results showed different concentrations of MOL-AgNPs exhibited significantly higher larvicidal activity (p<0.05). In the 4th instar, 67.5%, 82.5%, and 95% larval mortality were observed in MOL-AgNPs at 500 ppm after 24, 48, and 72 h of the larval exposure, respectively. Similarly in the 5th instar larvae, 72.5% (24 h), 83.75% (48 h), and 90% (72 h) mortality was observed after larval exposures to maximum concentration (500 ppm) of MOL-AgNPs. The 6th instar larvae showed 52.5% (24 h), 57.5% (48 h), and 85% (72 h) percentage mortality at 500 ppm. The MOL-AgNPs demonstrated high larvicidal activity which increased with the increase in concentrations of MOL-AgNPs and duration of exposure. The concentration levels with increased duration of exposure resulted in higher larval mortalities in all three larval instars. However, a more pronounced impact of larvicidal activity was observed on the 4th and 5th instars as compared to the 6th instar. The mortality rates recorded for both the concentration of the nanoparticles and the duration of exposure highlighted the potential of MOL-AgNPs as an eco-friendly and effective pest management strategy.

Os Estruturalistas Latino-Americanos e as Teorias da Inflação Inercial
Authors: IASCO-PEREIRA HUGO C. , RONCAGLIA ANDRÉ , CURADO MARCELO
Published: December 2024

RESUMO O objetivo deste estudo consiste em reinterpretar as teorias da inflação inercial ante aos debates metodológicos sobre os determinantes da produção científica para entender se o inercialismo foi uma “revolução científica” em relação ao paradigma macroeconômico estabelecido na primeira metade da década de 1980 e/ou uma continuidade da abordagem dos estruturalistas dos anos 1950. Para tanto, buscou-se identificar um “núcleo duro” de elementos teóricos comuns das diferentes abordagens, reconstituindo o debate entre monetaristas e inercialistas na década de 1980 como uma segunda rodada da controvérsia monetarista-estruturalista da década de 1950. Os resultados indicam que o inercialismo é mais bem situado como um programa de pesquisa alternativo ao mainstream dos anos 1980, mas que mantém elevado grau de originalidade como um desenvolvimento teórico posterior da abordagem estruturalista latino-americana.

Abstract: Undergraduate students are often impacted by depression, anxiety, and stress. In this context, machine learning may support mental health assessment. Based on the following research question: “How do machine learning models perform in the detection of depression, anxiety, and stress among undergraduate students?”, we aimed to evaluate the performance of these models. PubMed, Embase, PsycINFO, and Web of Science databases were searched, aiming at studies meeting the following criteria: publication in English; targeting undergraduate university students; empirical studies; having been published in a scientific journal; and predicting anxiety, depression, or stress outcomes via machine learning. The certainty of evidence was analyzed using the GRADE. As of January 2024, 2,304 articles were found, and 48 studies met the inclusion criteria. Different types of data were identified, including behavioral, physiological, internet usage, neurocerebral, blood markers, mixed data, as well as demographic and mobility data. Among the 33 studies that provided accuracy assessment, 30 reported values that exceeded 70%. Accuracy in detecting stress ranged from 63% to 100%, anxiety from 53.69% to 97.9%, and depression from 73.5% to 99.1%. Although most models present adequate performance, it should be noted that 47 of them only performed internal validation, which may overstate the performance data. Moreover, the GRADE checklist suggested that the quality of the evidence was very low. These findings indicate that machine learning algorithms hold promise in Public Health; however, it is crucial to scrutinize their practical applicability. Further studies should invest mainly in external validation of the machine learning models.

METHODS: A total of 113 patients with normal pancreatic enzyme levels diagnosed with coronavirus disease 2019 and 120 patients with both coronavirus disease 2019 diagnosis and high pancreatic enzyme levels were included in the study. The rs7041 genotyping of the 11th single nucleotide variation in the vitamin D-connector protein gene was determined by polymerase chain reaction and restriction fragment length polymorphism methods. RESULTS: In the patient group with coronavirus disease 2019 diagnosis and high pancreatic enzyme levels, the vitamin D-connector protein gene rs7041 variance GG genotype ratio was determined to be higher than the normal coronavirus disease 2019 patients. As a result of comparisons between the two groups, the difference between the genotype ratios in the relationship was determined to be statistically significant (p=0.004). CONCLUSION: Coronavirus disease 2019 patients were determined that the rs7041 halves in the vitamin D-connector protein gene could be prone to pancreatitis formation. Different populations and work with more patient groups are needed to verify the results of the study.

Resumo Introdução: Nova estratégia de terapia de indução com dose única de 3 mg/kg de globulina antitimócitos de coelho (r-ATG) mostrou menor incidência de rejeição aguda. Métodos: O objetivo foi utilizar dados do mundo real para determinar a razão de custo-efetividade incremental (RCEI) da indução com r-ATG para prevenção da rejeição aguda (RA) no primeiro ano pós-transplante renal e para sobrevida do enxerto renal em 1, 4 e 10 anos pós-transplante, sob a perspectiva do sistema nacional de saúde pública. Desenvolveu-se um modelo de transição de estado de Markov utilizando dados do mundo real extraídos de faturas médicas de um único centro. A população do estudo consistiu em adultos com baixo risco imunológico submetidos ao primeiro transplante, recebendo rins de doadores vivos ou falecidos. A intervenção de indução com r-ATG foi comparada à não-indução. Os desfechos clínicos considerados para essa análise foram rejeição aguda, infecção/doença por citomegalovírus, óbito, perda do enxerto e retransplante. Resultados: Análise de custo-efetividade no primeiro ano revelou que o grupo r-ATG foi mais custo-efetivo, com RCEI de US$ 399,96 por episódio de RA evitado, ganho de efetividade de 0,01 ano na sobrevida do enxerto e custo incremental total de US$ 147,50. As análises de 4 e 10 anos revelaram ganho de efetividade de 0,06 e 0,16 anos na sobrevida do enxerto no grupo de indução com r-ATG e custo incremental total de US$ −321,68 e US$ −2.440,62, respectivamente. Conclusão: A dose única de 3 mg/kg de r-ATG é custo-efetiva na prevenção de episódios de RA e dominante no longo prazo do transplante, conferindo ganho de sobrevida.

Resumo Introdução: Pesquisa multicêntrica em centros de diálise brasileiros são escassas. Descrevemos as fases de recrutamento e implementação do estudo SARC-HD, visando investigar a sarcopenia e seu impacto em desfechos clínicos adversos. Métodos: O SARC-HD é um estudo de coorte realizado com pacientes em hemodiálise no Brasil. A fase de recrutamento foi considerada o período entre convite ao centro e início da inclusão de pacientes, enquanto a fase de implementação durou a partir de então até a conclusão do recrutamento e coleta de dados basais. Após a implementação, um questionário estruturado foi distribuído para coletar feedback dos principais pesquisadores. Resultados: 21 centros de três regiões brasileiras consentiram em participar, com duas desistências. Dez pesquisadores principais supervisionaram 19 locais. Nove centros (47%) eram totalmente financiados por planos de saúde. 1525 pacientes foram avaliados para elegibilidade e 1008 foram incluídos, com taxa de recrutamento de 66,1%. Recrutamento e coleta de dados basais levaram 12 semanas [intervalo interquartil: 5–15]. A análise qualitativa de conteúdo identificou barreiras como falta de infraestrutura e logística para pesquisa. Os facilitadores incluíram gestão e organização do comitê gestor. Os desafios da coleta de dados foram relatados principalmente quanto à avaliação global subjetiva de 7 pontos e o questionário internacional de atividade física. O principal desafio para a fase de manutenção será a falta de informações padronizadas nos prontuários eletrônicos. Conclusões: As fases de recrutamento e implementação do estudo multicêntrico SARC-HD foram viáveis. Barreiras e facilitadores identificados pelos pesquisadores principais podem auxiliar futuras iniciativas multicêntricas a integrar tarefas relacionadas à pesquisa na rotina clínica, facilitando experiências bem-sucedidas.

ABSTRACT Purpose: To mitigate ischemia-reperfusion injury (IRI) triggered in solid organ transplant procedures, we aimed to evaluate the effects of multi-organ abdominal ischemic preconditioning (MAIP) in the context of renal IRI. Methods: An experimental kidney transplant model was conducted. Rats were divided into three groups: an intervention free basal group from which physiological data was collected; a control group (CT), which consisted of transplanted animals without MAIP; and a treated group, in which a MAIP protocol was implemented in the donor during the procurement of the left kidney, monitoring the recipient for 24 hours. Results: Urea, creatinine, and lactate dehydrogenase, as well as histopathological analysis (Banff: CT 1,66 ± 0,57 vs. basal 0, and MAIP 1), showed a clear trend in favor of MAIP group. Similar results were observed for tumor necrosis factor-α, interleukin-6 and CXCL10, as well as indicators of oxidative stress, with statistically significant levels for CXCL10 [0,295 ± 0,0074 arbitrary units (AU) CT and 0,0057 ± 0,0065 AU MAIP] and TBARS (2,93 ± 0,08 nmol/μg CT; and 2,49 ± 0,23 nmol/μg MAIP; p 0.05). Conclusion: The findings indicated that the MAIP exerts a protective influence on the transplanted kidneys, functioning as an IRI-protective strategy and enhancing the parameters associated with renal graft functionality.
Casamento infantil e opressão de gênero: uma abordagem socioecológica

Published: December 2024

Neste artigo, argumentamos que o casamento infantil deve ser entendido como uma prática social opressiva direcionada a meninas e mulheres, sustentada por uma estrutura normativa complexa que reforça estruturas e dinâmicas patriarcais. Baseamos nossa análise em uma perspectiva feminista e socioecológica da teoria das normas sociais, destacando a influência das normas de gênero e do contexto social e político. Em seguida, exploramos o papel da agência e da deliberação de meninas e adolescentes em contextos marcados por injustiça e opressão de gênero, utilizando teorias não-ideais para aprofundar a compreensão das estratégias que orientam a escolha dessas jovens por essa prática.

Authors: Espinoza-Román Hector G.
Published: December 2024

En el presente trabajo de investigación se comparan varios métodos de solución para la ecuación de presión para un caso de flujo incompresible. El objetivo es medir el tiempo de cálculo y la memoria de trabajo requerida por cada método para determinar cuál de los métodos de solución funciona mejor para un caso de flujo en estado estable e incompresible. Se analizan seis métodos de solución: Cholesky incompleto diagonal (DIC), Cholesky incompleto diagonal rápido (FDIC), Gauss-Seidel, Gauss-Seidel simétrico, Cholesky incompleto diagonal combinado con Gauss-Seidel (DICGaussSeidel) y Gauss-Seidel no-bloqueante. Se utiliza el tutorial airFoil2D como problema modelo. Se trabaja con la malla original del tutorial y con una malla refinada basada en la original. Se determina que el mejor método en términos de tiempo de cálculo es el método FDIC. En cuanto a memoria requerida, todos los métodos tienen requerimientos similares.

We are grateful for the feedback on our paper. We support the respondent’s view that there is considerable opportunity to improve our understanding of existing bridge assets, and increase our collective ability to reuse, repurpose and extend the life of these structures. We highlight this issue in section 4.2 of our paper, where we make reference to structural health monitoring, data collection and analytics. We support the view that greater use of data from archive searches, instrumentation and monitoring, and structural investigations can provide the evidence base to support better decision-making. The Net Zero Bridges Group (NZBG) is working on further guidance which will be shared on our website, and we encourage others to share their ideas and activity in this area. We welcome any case studies where investment in obtaining better asset data has been shown to lead directly to lower-emission outcomes.
Transforming Scottish Water’s asset management to ensure sustainable investment decisions

Published: December 2024

In this article, we explain how Scottish Water, a water and wastewater management organisation, is transforming its asset management to ensure sustainable investment decisions, that is stakeholder aligned, transparent, and evidence-based investment decisions. This includes identification of the main types of investment decisions and the main areas of work required to ensure the decisions are made with the right data and analytics and with the right engagement with stakeholders. We also share Scottish Water’s reasons for embarking on the 10-year transformation and its vision for the future, as well as our experiences. The main takeaways in year 5 of the transformation are as follows: there is no one-size-fits-all blueprint for a transformation; modelling and understanding the organisational decision-making processes is an important step in transforming asset management; transparency as to the data used to develop analytical models, how the analytical models work, and which of the costs, benefits, and risks are considered is likely to identify that not all decision makers are fully aware of the limitations of the data and analytical models used in decision making; and the engagement and long-term commitment of both internal and external stakeholders are essential in a successful transformation.
