Nanoparticles of TiO2 doped with low amount of Fe were synthesized from natural ilmenite obtained from alluvial gold mine wastes. The obtained TiO2 were characterized using X-ray diffraction (XRD), X-ray fluorescence (XRF), Fourier-transform infrared spectroscopy (FTIR), UV-Vis diffuse reflectance, thermogravimetric analysis/differential scanning calorimetry (TGA/DSC), N2 adsorption-desorption isotherms, transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The results confirm the formation of mesoporous TiO2 nanoparticles in anatase phase with 0.05 wt.% of iron possibly replacing some titanium places. All the characterizations were performed to the synthesized solid and the reference materials (TiO2 anatase and Degussa P25). The photocatalytic activity of both the synthesized solid and references were evaluated in the photo-oxidation of cyanide in aqueous medium under UV illumination. An experimental design type Box-Behnken was performed choosing three different parameters: the initial concentration of cyanide (50, 150 and 250 ppm) the catalyst load (0.1, 0.5 and 1.0 g L-1) and the oxygen source. The percentage of cyanide conversion was chosen as response in the design obtaining as optimal conditions [CN-]0 = 50 ppm, catalyst load = 0.6 g L-1 and air bubbling. Under these conditions it was reached 32, 32 and 89% of cyanide conversion for Fe-TiO2 synthesized, TiO2 anatase and Degussa P25, respectively.

Cupuaçu (Theobroma grandiflorum Schum.) is an Amazonian fruit rich in antioxidants potential due to its phenolic compounds. Its seeds produce cupulate, a chocolate-like product, and the residue remains rich in biocompounds. This study aimed to optimize and compare microwave-assisted (MAE) and high pressure/temperature extraction (HPTE) of polyphenolic and flavonoid compounds from cupuaçu seed by-products. A Box-Behnken 33 factorial design assessed the influence of extraction time, solid/liquid ratio, and ethanol concentration. Responses included total polyphenol content, total flavonoid content, and anti-radical power via the ABTS (2,2-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid) method. In optimum conditions, MAE had the highest total polyphenol content and HPTE for flavonoids. Optimal conditions for both methods were 65% (m/v) ethanol concentration, 45 min extraction time, and 0.03 g mL−1 solid/liquid ratio. MAE and HPTE achieved greater recovery of (−)-epicatechin and (−)-epigallocatechin-3-gallate compared to percolation. Both techniques proved viable for recovering polyphenols from cupuaçu seed by-products, in less time and with less solvent. Thus, cupuaçu by-products can be a sustainable and functional food source, with MAE and HPTE providing high yields and quality extracts rich in polyphenols. Theobroma Schum.

ABSTRACT Introduction: This project aimed to recognize relational intelligence as an instrument of cohesion, satisfaction, and professional motivation with inherent repercussions on the quality and safety of care provided, as well as the promotion of healthy work environments. Diagnosis: Was use consensus research to identify the area of intervention, more specifically the “brainstorming” technique, prioritizing relational issues based on the number of times they were mentioned by employees. Objective: Promote relational intelligence in the team at the Surgery A unit, at Hospital Curry Cabral, as a management tool, increasing employee satisfaction in relation to the work environment by at least 20%. Methodology: The methodology used focused on two assessment moments, qualitative and quantitative. The qualitative assessment began with the project “Thinking outside the box…writing inside the box”, in which employees were encouraged to share emotions, suggestions, compliments, complaints, or any other subject they considered relevant. The anonymity of the contributions allowed sincerity and directness in the work environment to emerge without constraints, allowing psychological safety. This strategy was the “driver” of this project because, based on its contributions, it was possible to identify areas that could be improved. For a quantitative analysis, to measure the intended objective, was applied questionnaires on two evaluation moments. Results: With the contributions of the qualitative assessment, mas observed the need for intervention in terms of employees’ mental health. This began new routines, which include weekly reflection meetings, training on interpersonal relationships and health and well-being measures in the team. The strategies used allowed the results obtained in the quantitative evaluation with an increase of 44,1% in the satisfaction of this population. Conclusion: There is an association of the ability to actively listen to employees’ problems and their involvement. Participatory, transformative, and humanized leadership contributed to the well-being of professionals. If is therefore considered that this project added value in terms of improving the working environment, with repercussions on productivity and the quality of service provided to users.

RESUMO Introdução: Este projeto visa reconhecer a inteligência relacional como instrumento de coesão, satisfação e motivação profissional, com inerente repercussão na qualidade e segurança dos cuidados prestados, bem como na promoção de ambientes de trabalho saudáveis. Diagnóstico da situação: Procedeu-se ao diagnóstico da situação utilizando-se a pesquisa de consenso, mais especificamente a técnica de “brainstorming”, para identificar a área de intervenção, priorizando-se as questões relacionais pelo número de vezes que foram mencionadas pelos colaboradores. Objetivo: Promover a inteligência relacional na equipa da unidade Cirurgia A, do Hospital Curry Cabral, como instrumento de gestão, aumentando em pelo menos 20% a satisfação dos colaboradores, em relação ao ambiente de trabalho. Metodologia: A metodologia focou-se em dois momentos de avaliação, qualitativa e quantitativa. A primeira iniciou-se com o projeto “Pensar fora da caixa…escrevendo para dentro da caixa”- nesta os colaboradores foram estimulados a partilhar emoções, sugestões, elogios, reclamações ou qualquer outro assunto que considerassem pertinente. O anonimato dos contributos permitiu que a sinceridade e frontalidade sobre o ambiente de trabalho emergisse sem constrangimentos e em segurança psicológica. Esta estratégia foi, sem dúvida, o “motor” deste projeto pois, a partir dos seus contributos, foi possível identificar as áreas passiveis de melhoria. Para uma análise quantitativa, de forma que existissem indicadores para medir o objetivo pretendido, foram realizados dois momentos de avaliação através da aplicação de questionários. Resultados: Com os contributos da avaliação qualitativa observou-se a necessidade de intervenção a nível da saúde mental dos colaboradores. Deu-se assim inicio a novas rotinas, onde se incluíram reuniões semanais de reflexão, formação sobre relacionamento interpessoal e medidas de saúde e bem-estar na equipa. As estratégias utilizadas permitiram os resultados obtidos na avaliação quantitativa com um aumento de 44,1% na satisfação desta população. Conclusões: A capacidade de escuta ativa dos problemas dos colaboradores e o envolvimento dos mesmos na sua melhoria associado a uma liderança participativa, transformadora e humanizada contribuiu para o bem-estar dos profissionais. Considera-se assim que este projeto acrescentou valor no que diz respeito à melhoria do ambiente de trabalho, com repercussão na produtividade e na qualidade do atendimento feito aos utentes.

Abstract Background: Verbesina molinaria B.L. Rob. & Greenm. and V. oncophora B.L. Rob. & Seaton constitute species with conflicting circumscription; different authors consider them as two different or just one species (V. oncophora). Questions: ¿Are they one or two species of Verbesina? ¿A linear discriminant analysis (LDA) will differentiate them as two species? Species studied/Mathematic model: Verbesina molinaria and V. oncophora / Royston, Shapiro-Wilk, Levene, correlation (Pearson), Variance inflation factor (VIF), and LDA. Study site and years: Mexico; 2022-2023. Methods: Types, protologues, as well as herbarium specimens at ENCB, HUMO, MEXU, and UAMIZ of the two species were analyzed, assigning a preliminary name to each one. A data matrix with the characters and character states was created to carry out the statistical analyses. Box plots were generated to evaluate differences among characters and the statistical tests were done using the software Rstudio. Results: Types and protologs analyses revealed morphological differences between both species. Royston and Shapiro-Wilk tests supported normality among characters evaluated, and the Levene test suggests there are no significant differences among them. Finally, Pearson correlation and the VIF values suggested the absence of correlation or collinearity. The LDA analysis showed 100 % accuracy in the assigning of specimens to the a priori species allocated. Conclusions: The two species represent distinct taxa based on the morphological differences and statistical support, one of them widespread in central Mexico (V. oncophora) and the other (V. molinaria) restricted as far as now to the states of Mexico, Morelos, and Michoacán.

Rob. & Seaton son especies con circunscripción conflictiva; algunos autores las consideran como especies distintas mientras que otros como una sola (V. oncophora). Preguntas: ¿Son dos especies de Verbesina? ¿Un análisis linear discriminante (LDA) ayudará a diferenciarlas? Especies de estudio/Modelo matemático: Verbesina molinaria y V. oncophora / Pruebas de Royston, Shapiro-Wilk, Levene, correlación (Pearson), factor de inflación de la varianza (VIF) y LDA. Sitio y años de estudio: México; 2022-2023. Métodos: Se revisaron tipos, protólogos, así como ejemplares de ambas especies depositados en ENCB, HUMO, MEXU y UAMIZ, asignándoles un nombre preliminar y elaborando una matriz de datos. Se generaron diagramas de cajas para evaluar diferencias entre los caracteres analizados; las pruebas estadísticas se realizaron utilizando el software Rstudio. Resultados: Los tipos y protólogos permitieron identificar diferencias morfológicas entre ellas. Las pruebas de Royston y Shapiro-Wilk respaldaron la normalidad entre los caracteres evaluados. La prueba de Levene sugiere que no hay diferencias significativas entre los caracteres; finalmente, la correlación de Pearson y el VIF indican ausencia de correlación o colinealidad. El análisis LDA mostró una precisión del 100 % en la asignación de los ejemplares con las asignaciones a priori. Conclusiones: Las diferencias morfológicas y las pruebas estadísticas, apoyan el reconocimiento de dos entidades distintas, V. oncophora con amplia distribución en el centro de México y V. molinaria con distribución más restringida, mejor conocida hasta la fecha en los estados de México, Michoacán y Morelos.

ABSTRACT Introduction: According to Barros (2017), Bentonite is a mixture of clays, generally impure, very fine grained, formed mainly by 60 to 80% of montmorillonite and also Kaolinite, Calcite and Pyrite. At the operational base of Petromoc Maputo Company, there is a set of tanks for fuel storage, that from a complex of tanks with coupled pipelines for the entry and withdrawal of fuels and effluent disposal. Objective: To evaluate the use of bentonite in the removal of toxic cations from the effluents generated at Petromoc Company. Materials and Methods: Bentonite samples were collected at the Industrial Minerals company. The effluent and influent samples were collected in the separator box of the operational base. The physicochemical experiments were carried out at the Analytical Chemistry Laboratory of the Eduardo Mondlane University. For the physical characterization of the bentonite, the pycnometric density, porosity (P) and specific surface area were determined. The mineralogical characterization was performed by X-ray diffraction analysis. The chemical characterization of the effluent and influent was performed by Inductively Coupled Plasma Atomic Emission Spectroscopy. Results and Discussion: Mineralogical characterization showed the presence of bentonite minerals. The pH of the effluent before interacting with the bentonite was 3.22, after interaction the pH is between 5.8 and 9. High concentrations of Cadmium (Cd), Chromium (Cr), Copper (Cu), Titanium (Ti) and Zinc (Zn) were determined in the effluent before the interaction with the bentonite. After the interaction, a removal of toxic elements is verified. Conclusions: The bentonite showed high efficiency in the removal of toxic cations.

RESUMEN In recent decades, glacier retreat has been observed in all the world’s mountain ranges. Over the last 20 years, glaciers in the Andes have lost mass at one of the highest rates on record. Particularly, glaciers in the northern Patagonian Andes show the highest rate of loss of all the Andean regions for the last decade. Detailed records of long-term variations in glacier extent are crucial to put current climate change into context and quantify its impact on mountain areas. In the present study, a reconstruction of the extension (length and area) of the Alerce glacier (41.15° S-71.81° W) for the last 70 years was carried out. By means of historical documents and satellite images (Landsat and Pléiades), detailed maps of glacier fluctuations were generated for the period 1953-2020. Four methodologies were evaluated to measure the front position: i) central flow line; ii) curvilinear box; iii) multiline; and iv) variable box. The magnitude of the front position variations depends on the methodology applied. The method that best addresses glacier front variations over the period analyzed is the variable box method. Between 1953 and 2020, the Alerce glacier lost 35% of its area (1.1±0.1 km2) and 67% of its total length (1.49±0.04 km). It is possible to distinguish periods with different rates of retreat. A stage of slight retreat (-11.3±0.5 ma-1) between 1953 and 1976, followed by a period of stability (-6.7±0.5 ma-1) between 1977 and 1983, then a strong retreat (-58.7±0.5 ma-1) between 1984 and 1999, followed by another period of stability (-5.4±0.5 ma-1) between 2000 and 2009 and, finally, another retreat (-8.7±0.5 ma-1) between 2010 and 2020. The retreat rates for the Alerce glacier mimic those observed in other glaciers in the region, possibly representing a regional climatic signal.

ABSTRACT En las últimas décadas se ha observado un retroceso de los glaciares en todos los cordones montañosos del mundo. Durante los últimos 20 años, los glaciares de los Andes perdieron masa a una tasa sin precedentes en el registro histórico. En particular, los glaciares de Patagonia norte son los que presentan la mayor tasa de pérdida de todas las regiones andinas para la última década. Contar con registros detallados sobre las variaciones en la extensión de los glaciares en el largo plazo es crucial para poner en contexto el cambio climático actual y cuantificar su impacto en zonas de montaña. En el presente estudio se realizó la reconstrucción de la extensión (área y longitud) del glaciar Alerce (41,15° S-71,81° O) para los últimos 70 años. Utilizando una combinación de documentos históricos e imágenes satelitales (Landsat y Pléiades), se generó cartografía de detalle para cuantificar las fluctuaciones del frente del glaciar Alerce para el período 1953-2020. Se evaluaron cuatro metodologías para medir la posición del frente: i) línea central de flujo; ii) caja curvilínea; iii) multilínea; y iv) caja variable. La magnitud de la variación del frente depende de la metodología aplicada. El método que mejor contempla la variación del frente del glaciar a lo largo del período analizado es el de caja variable. Entre 1953 y 2020, el glaciar Alerce perdió el 35% de su superficie (1,1±0,1 km2) y el 67% de su longitud total (1,49±0,04 km). Es posible distinguir períodos con diferentes tasas de retroceso. Una leve (-11,3±0,5 ma−1) entre 1953 y 1976, seguida de un período de relativa estabilidad (-6,7±0,5 ma−1) entre 1977 y 1983, luego un marcado retroceso (-58,7±0,5 ma−1) entre 1984 y 1999, otro período de estabilidad (-5,4±0,5 ma−1) entre 2000 y 2009 y, finalmente, otra etapa de retroceso (-8,7±0,5 ma−1) entre 2010 y 2020. Las tasas de retroceso para el glaciar Alerce coinciden con las observadas en otros glaciares de la región, lo cual puede representar una señal climática regional.

ABSTRACT Techniques such as fertilization can be used more frequently to achieve higher crop yields. The problem of excessive use of fertilizers is related to losses of nutrients by leaching contaminating water bodies. Adopting controlled-release fertilizers may favor the reduction of losses and the total cost of fertilization as the number of applications is reduced. This research aimed to study the dynamics of nutrients from polymer-coated fertilizers (KNO3 controlled-release polymers) in sandy soil and analyze the spatial variation of soil solution storage at different depths when drip irrigation is adopted. Four soil boxes filled with Quartzipsamment and equipped with a mesh of 19 TDR probes were used to monitor soil moisture and electrical conductivity. Three soil boxes received the treatment of 50 g of the controlled-release polymer, and one soil box was used as a control. One liter of water was applied weekly through a drip irrigation system for ten weeks, followed by readings from the TDR probes to monitor the spatial variation of the soil solution storage in the soil profile. This monitoring allowed verifying that the release of nutrients happened slowly and gradually over the period without water retention by the material. The solution was displaced by advection (mass flow) and dispersion along with the irrigation water, which advanced more than the nutrients within the profile, reducing their leaching. Thus, controlled-release polymers maintained a slow and variable release over time. yields bodies controlledrelease controlled reduced polymercoated polymer coated KNO3 KNO (KNO adopted 1 conductivity 5 control weeks profile material mass flow Thus time

Abstract Time series analysis is a useful tool for many practical water resource management applications, such as planning and anticipating conflict around water use. These analyses are also necessary for the use, design and operation of hydrotechnical works and for the protection of aquatic ecosystems. Basically, his review focuses on classic models such as Box and Jenkins. However, restrictive assumptions about data and residuals make its use difficult. As an alternative, non-parametric approaches are interesting due to their application versatility. One of the techniques that has been widely used in the analysis of flow time series is Singular Spectral Analysis (SSA). However, its application is concentrated as a pre-processor or in hybrid approaches and, because of this, many studies focus only on the model to be improved, leaving gaps in the process understanding that underlie the SSA. Within this context, and because of this, the objective of this study is to present the SSA technique in detail, through an application to a time series of monthly average flows with complex behavior (Jucu River, located in Southeast Brazil), in order to overcome gaps associated to a rigorous understanding of the procedures that make up the SSA. The Sequential SSA technique was used to decompose signal and noise components. The reconstructed series preserved the dynamics of the observed series, suggesting a strong influence of the signal component (trend and seasonality) on its behavior. It’s expected that the technique can be used with greater fluidity by specialists and contribute to the management of water resources. applications ecosystems Basically Jenkins However difficult alternative nonparametric non parametric versatility .

Resumo A análise de séries temporais é uma ferramenta útil para muitas aplicações práticas de gestão de recursos hídricos, como no planejamento e antecipação de conflitos em torno do uso d'água. Estas análises são também necessárias para a concepção e operação de obras hidrotécnicas e para a proteção de ecossistemas aquáticos. Basicamente, sua análise se concentra em modelos clássicos, como Box e Jenkins. No entanto, suposições restritivas sobre dados e resíduos dificultam seu uso. Como alternativa, abordagens não paramétricas são interessantes devido a sua versatilidade de aplicação. Uma das técnicas que têm sido amplamente utilizada na análise de séries temporais de vazão é a Análise Espectral Singular (SSA). No entanto, sua aplicação é concentrada como pré-processador ou em abordagens híbridas e por conta disso, muitos estudos se concentram apenas no modelo a ser aprimorado, deixando lacunas de entendimento dos processos que fundamentam a SSA. Dentro desse contexto, e por conta disso, o objetivo deste estudo é apresentar detalhadamente a técnica SSA, através de uma aplicação à uma série temporal de vazões médias mensais com comportamento complexo (rio Jucu, localizado no Sudeste do Brasil), a fim de superar lacunas associadas ao entendimento rigoroso dos procedimentos que compõem a SSA. A SSA Sequencial foi utilizada para decompor os componentes sinal e ruído. A série reconstruída preservou a dinâmica da série observada, sugerindo forte influência do sinal (tendência e sazonalidade) em seu comportamento. Espera-se que a técnica possa ser usada com maior fluidez pelos especialistas e contribuir na gestão dos recursos hídricos. hídricos dágua. dágua d água. água d'água aquáticos Basicamente clássicos Jenkins entanto alternativa .

ABSTRACT The objective of this research was to evaluate the biochemical and physiological quality of peanut cultivar seeds under periods of imbibition and drying. A completely randomized statistical design was adopted, in factorial scheme, with four replications. The three peanut cultivars were: BR1, BRS 151-L7, and IAC 505. The imbibition and drying periods were: 0, 12, 24, 36 and 48 hours. The seeds were imbibition with the aid of germitest paper and distilled water, then dried on a metal screen in a plastic box with silica, according to the periods studied. Physiological variables were evaluated (percentage of germination, normal seedlings, abnormal seedlings in the first count and abnormal seedlings in the final count, accelerated aging, seedling length, electrical conductivity, speed index, and average germination time) and biochemical variables (sugar concentration total, reducing sugars, hydrogen peroxide, total superoxide dismutase proteins, and total proteins). The desiccation tolerance of peanut seeds is reduced as the period of water absorption followed by drying increases. Seeds of cultivar IAC 505 have greater tolerance to imbibition and subsequent desiccation compared to seeds of BR1 and BRS 151-L7. adopted scheme replications BR 151L7, 151L7 L 151 L7, L7 151-L7 0 12 24 3 4 hours silica studied percentage aging length conductivity index time sugar sugars peroxide proteins proteins. . proteins) increases 50 151L7.

ABSTRACT Introduction: Atrial fibrillation is one of the common complications of mitral valve disease. Currently, in the absence of freezing equipment, it’s still impossible to fully conduct a minimally invasive Cox-maze IV procedure to treat atrial fibrillation. Methods: We analyzed the clinical data of 28 patients who underwent thoracoscopic minimally invasive mitral valve full maze surgery in our hospital from October 2021 to September 2022; 13 patients were male and 15 were female, three suffered from paroxysmal atrial fibrillation, and 25 suffered from permanent atrial fibrillation; average age was 61.88±8.30 years, and mean preoperative left atrial diameter was 47.12±8.34 mm. Isolation of left atrial posterior wall (box lesion) was completed in all patients by cut-and-sew technique and bipolar clamp ablation. Results: For these subjects, the median cardiopulmonary bypass time was 169 (109.75-202.75) minutes, aortic cross-clamping time was 106 (77.75-125.50) minutes, and ventilator assistance time was 6.5 (0-10) hours. Among them, eight subjects had the endotracheal tubes removed immediately after surgical operation. Three subjects were in the blanking period; two subjects still had atrial fibrillation at three months after operation, one of whom resumed sinus rhythm after electrical cardioversion therapy; and all the remaining 23 subjects had sinus rhythm. Conclusion: The minimally invasive cut-and-sew technique for electrical isolation of left pulmonary veins can improve sinus conversion rate of patients suffering from both mitral valve disease and atrial fibrillation. In selected subjects, it is safe and has good results in the short-term postoperative period.

Abstract As opencast coal production increases, a crucial challenge is safeguarding the stability and management of overburden dumps while prioritizing both safety and cost-efficiency. Determining the optimal stable dump slope dimensions during and after mining remains a key challenge for mining operations worldwide. Assessing the stability of overburden (OB) dumps is necessary to maintain them at the steepest possible angle without compromising stability. Understanding the shear strength, including cohesion and angle of internal friction, of the heterogeneous dump mass is crucial for this assessment. To evaluate the shear strength behaviour of OB materials, a large direct shear machine (LDSM) was designed and developed at Central Mine Planning and Design Institute, Ranchi. The LDSM features a shear box with dimensions of 1000 mm × 1000 mm × 1000 mm to facilitate testing materials with larger particle sizes. It can test large specimens with a thickness up to 500 mm and a maximum particle size (Dmax) of 80mm in accordance with ASTM D3080-98. Seven different OB materials from Magadh Coalfields, India were collected and tested for their shear strength. Using the obtained shear strength parameters, various slope profiles are assessed for stability using 2D limit equilibrium software such as Slide2 and GALENA. Probabilistic modelling is employed to generate a statistically distributed factor of safety (FoS) instead of a deterministic value, accounting for uncertainties related to input parameters. This paper aims to forecast the maximum safe height for OB dumps based on the determined shear strength parameters. increases costefficiency. costefficiency cost efficiency. efficiency cost-efficiency worldwide (OB friction assessment (LDSM Institute Ranchi 100 sizes 50 Dmax (Dmax D308098.

ABSTRACT Advances in treatment of structural heart disease have been disruptive to cardiovascular surgery, and there have been discussions about how to incorporate these technologies into the surgeons’ therapeutic arsenal. Transcatheter procedures, complex redo interventions, and endovascular aortic approaches are already practiced by cardiovascular surgeons in Brazil. The expansion of these techniques, coupled with recent changes in the country’s medical residency program in cardiovascular surgery, has led to an urgent need to acquire catheter-based skills. In this article, we discuss these aspects in the light of the reality of cardiovascular surgery training in Brazil. arsenal procedures interventions Brazil techniques countrys country s catheterbased catheter based skills article

Forkhead Box O1 (FOXO1) has been reported to play important roles in many tumors. However, FOXO1 has not been studied in pan-cancer. The purpose of this study was to reveal the roles of FOXO1 in pan-cancer (33 cancers in this study). Through multiple public platforms, a pan-cancer analysis of FOXO1 was conducted to obtained FOXO1 expression profiles in various tumors to explore the relationship between FOXO1 expression and prognosis of these tumors and to disclose the potential mechanism of FOXO1 in these tumors. FOXO1 was associated with the prognosis of multiple tumors, especially LGG (low grade glioma), OV (ovarian carcinoma), and KIRC (kidney renal clear cell carcinoma). FOXO1 might play the role of an oncogenic gene in LGG and OV, while playing the role of a cancer suppressor gene in KIRC. FOXO1 expression had a significant correlation with the infiltration of some immune cells in LGG, OV, and KIRC. By combining FOXO1 expression and immune cell infiltration, we found that FOXO1 might influence the overall survival of LGG through the infiltration of myeloid dendritic cells or CD4+ T cells. Functional enrichment analysis and gene set enrichment analysis showed that FOXO1 might play roles in tumors through immunoregulatory interactions between a lymphoid and a non-lymphoid cell, TGF-beta signaling pathway, and transcriptional misregulation in cancer. FOXO1 was associated with the prognosis of multiple tumors, especially LGG, OV, and KIRC. In these tumors, FOXO1 might play its role via the regulation of the immune microenvironment.

The extensive use of pesticides promoted the need for bioremediation methods, including for pyrethroids. Therefore, biodegradation of gamma-cyhalothrin by fungi from a Brazilian cave known as Gruta do Catão (São Desidério, Bahia, Brazil) was investigated. Experiments were conducted with Aspergillus ustus CBMAI 1894, Talaromyces brunneus CBMAI 1895, and Aspergillus sp. CBMAI 1926 in 2% malt liquid medium with 300 mg L-1 gamma-cyhalothrin (25 °C, 130 rpm, 21 days, pH 7.0). All strains biodegraded this insecticide, and the most efficient biocatalyst was A. ustus CBMAI 1894 with 50% biodegradation, even though reduced mycelial mass was observed in the presence of gamma-cyhalothrin. A three factor Box-Behnken design was carried out. Temperature and pesticide concentration influenced biodegradation, whereas pH was non-significant. In conclusion, cave fungi can be explored for bioremediation, and future studies should focus on understanding the enzymatic apparatus, physiology, and genetics behind these microorganisms, which can present unique properties for biotechnological applications. methods pyrethroids Therefore gammacyhalothrin gamma cyhalothrin São Desidério Bahia Brazil investigated 1895 sp 192 2 30 L1 L 1 L- 25 (2 C °C 13 rpm days 7.0. 70 7.0 . 7 0 7.0) insecticide 189 50 gammacyhalothrin. cyhalothrin.
