Guidelines for minimal information on cellular senescence experimentation in vivo.

Cellular senescence is a cell fate triggered in response to stress and is characterized by stable cell-cycle arrest and a hypersecretory state. It has diverse biological roles, ranging from tissue repair to chronic disease. The development of new tools to study senescence in vivo has paved the way for uncovering its physiological and pathological roles and testing senescent cells as a therapeutic target. However, the lack of specific and broadly applicable markers makes it difficult to identify and characterize senescent cells in tissues and living organisms. To address this, we provide practical guidelines called "minimum information for cellular senescence experimentation in vivo" (MICSE). It presents an overview of senescence markers in rodent tissues, transgenic models, non-mammalian systems, human tissues, and tumors and their use in the identification and specification of senescent cells. These guidelines provide a uniform, state-of-the-art, and accessible toolset to improve our understanding of cellular senescence in vivo.

Inhibition of IL-11 signalling extends mammalian healthspan and lifespan.

For healthspan and lifespan, ERK, AMPK and mTORC1 represent critical pathways and inflammation is a centrally important hallmark1-7. Here we examined whether IL-11, a pro-inflammatory cytokine of the IL-6 family, has a negative effect on age-associated disease and lifespan. As mice age, IL-11 is upregulated across cell types and tissues to regulate an ERK-AMPK-mTORC1 axis to modulate cellular, tissue- and organismal-level ageing pathologies. Deletion of Il11 or Il11ra1 protects against metabolic decline, multi-morbidity and frailty in old age. Administration of anti-IL-11 to 75-week-old mice for 25 weeks improves metabolism and muscle function, and reduces ageing biomarkers and frailty across sexes. In lifespan studies, genetic deletion of Il11 extended the lives of mice of both sexes, by 24.9% on average. Treatment with anti-IL-11 from 75 weeks of age until death extends the median lifespan of male mice by 22.5% and of female mice by 25%. Together, these results demonstrate a role for the pro-inflammatory factor IL-11 in mammalian healthspan and lifespan. We suggest that anti-IL-11 therapy, which is currently in early-stage clinical trials for fibrotic lung disease, may provide a translational opportunity to determine the effects of IL-11 inhibition on ageing pathologies in older people.

Carvacrol Encapsulation in Chitosan-Carboxymethylcellulose-Alginate Nanocarriers for Postharvest Tomato Protection.

Advancements in polymer science and nanotechnology hold significant potential for addressing the increasing demands of food security, by enhancing the shelf life, barrier properties, and nutritional quality of harvested fruits and vegetables. In this context, biopolymer-based delivery systems present themselves as a promising strategy for encapsulating bioactive compounds, improving their absorption, stability, and functionality. This study provides an exploration of the synthesis, characterization, and postharvest protection applications of nanocarriers formed through the complexation of chitosan oligomers, carboxymethylcellulose, and alginate in a 2:2:1 molar ratio. This complexation process was facilitated by methacrylic anhydride and sodium tripolyphosphate as cross-linking agents. Characterization techniques employed include transmission electron microscopy, energy-dispersive X-ray spectroscopy, infrared spectroscopy, thermal analysis, and X-ray powder diffraction. The resulting hollow nanospheres, characterized by a monodisperse distribution and a mean diameter of 114 nm, exhibited efficient encapsulation of carvacrol, with a loading capacity of approximately 20%. Their suitability for phytopathogen control was assessed in vitro against three phytopathogens-Botrytis cinerea, Penicillium expansum, and Colletotrichum coccodes-revealing minimum inhibitory concentrations ranging from 23.3 to 31.3 µg·mL-1. This indicates a higher activity compared to non-encapsulated conventional fungicides. In ex situ tests for tomato (cv. 'Daniela') protection, higher doses (50-100 µg·mL-1, depending on the pathogen) were necessary to achieve high protection. Nevertheless, these doses remained practical for real-world applicability. The advantages of safety, coupled with the potential for a multi-target mode of action, further enhance the appeal of these nanocarriers.

Aedes albopictus in a recently invaded area in Spain: effects of trap type, locality, and season on mosquito captures.

Mosquitoes are primary vectors of pathogens impacting humans, wildlife, and livestock. Among them, the Asian tiger mosquito, Aedes albopictus, stands out as an invasive species with a global distribution, having established populations on every continent except Antarctica. Recent findings incriminate Ae. albopictus in the local transmission of several pathogens causing human diseases, including dengue, chikungunya, and Zika viruses and worm parasites as Dirofilaria. In Spain, the establishment of Ae. albopictus occurred in 2004 and it rapidly expanded, currently reaching southern provinces and creating novel epidemiological scenarios in recently invaded areas. In this study, we conducted captures of Ae. albopictus from May to November 2022 in two provinces, Granada and Malaga, situated near the current edge of the species' expanding range in Spain. The objective was to identify the primary factors influencing their captures in these regions. Mosquitoes were captured using BG-Sentinel traps baited with CO2 and BG-Lure, and miniature CDC-UV traps in five different localities. Our findings underscore the influence of both extrinsic factors, such as locality, and intrinsic factors, including mosquito sex, on the abundance of captured Ae. albopictus. A higher abundance of Ae. albopictus was observed in the Malaga province compared to localities in the Granada province. Furthermore, similar numbers of Ae. albopictus mosquitoes were captured in more urbanized areas of Granada, while the lowest counts were recorded in the less urbanized area. These results were compared to captures of another common species in the area, specifically Culex pipiens. Overall, these results represent the first monitoring of invasive Ae. albopictus in the area and are discussed in the light of the potential importance of the species as a nuisance for humans and vectors of pathogens of public health relevance.

Detection of senescence using machine learning algorithms based on nuclear features.

Cellular senescence is a stress response with broad pathophysiological implications. Senotherapies can induce senescence to treat cancer or eliminate senescent cells to ameliorate ageing and age-related pathologies. However, the success of senotherapies is limited by the lack of reliable ways to identify senescence. Here, we use nuclear morphology features of senescent cells to devise machine-learning classifiers that accurately predict senescence induced by diverse stressors in different cell types and tissues. As a proof-of-principle, we use these senescence classifiers to characterise senolytics and to screen for drugs that selectively induce senescence in cancer cells but not normal cells. Moreover, a tissue senescence score served to assess the efficacy of senolytic drugs and identified senescence in mouse models of liver cancer initiation, ageing, and fibrosis, and in patients with fatty liver disease. Thus, senescence classifiers can help to detect pathophysiological senescence and to discover and validate potential senotherapies.

Phytochemical study of 'tajy' (Handroanthus impetiginosus (Mart.) Mattos) and 'ka'a oveti' (Luehea divaricata Mart.) extracts.

This study explores the phytochemical composition of leaf extracts from Handroanthus impetiginosus (Mart.) Mattos and Luehea divaricata Mart., used in a contraceptive decoction by Mbya-Guarani women. The phytocompounds were identified by gas chro-matography-mass spectrometry, while Fourier-transform infrared spectroscopy, multi-elemental, and thermal analyses were used to characterise plant biomass. Notably, no phytoconstituent supporting the efficacy of these extracts as female contraceptives was found, except for a small amount (0.3%) of sitosterol. Conversely, L. divaricata leaves contained compounds like 1,3-dihydroxyacetone dimer, N-methyl-N-nitroso-2-propanamine, 2-methoxy-N-(2-methoxyethyl)-N-methyl-ethanamine, and 1,3,5-triazine-2,4,6-triamine, potentially exerting cytotoxic, genotoxic, and toxicogenomic effects. Due to the absence of scientific support for the claimed contraceptive efficacy and the presence of safety concerns, we propose an alternative valorisation pathway centred on the presence of phytochemicals exhibiting antimicrobial activity. This proposition is substantiated by their considerable in vitro efficacy against Botrytis cinerea.

Definition of a microbial signature as a predictor of endoscopic post-surgical recurrence in patients with Crohn's disease.

Background and aims: Although there are several effective drugs for the treatment of Crohn's disease (CD), almost 70% of patients will require surgical resection during their lifetime. This procedure is not always curative, as endoscopic recurrence occurs in 65%-90% of patients in the first year after surgery. The aetiology of the recurrence is unknown; however, several studies have shown how the resident microbiota is modified after surgery. The aim of this study was to evaluate samples from patients with Crohn's disease before and after an intestinal resection to determine whether there were differences in the abundance of different microbial markers, which may predict endoscopic recurrence at baseline. Methods: In this observational study, a stool sample was obtained from 25 patients with Crohn's disease before undergoing surgery, recruited at three Catalan hospitals. From each sample, DNA was purified and the relative abundance of nine microbial markers was quantified using qPCR. Results: An algorithm composed of four microbial markers (E. coli, F. prausnitzii phylogroup I, Bacteroidetes, and Eubacteria) showed a sensitivity and specificity of 90.91% and 85.71%, respectively, and a positive and negative predictive value of 83.33% and 92.31%, respectively. Conclusion: A microbial signature to determine patients who will have post-surgical recurrence was identified. This tool might be very useful in daily clinical practice, allowing the scheduling of personalized therapy and enabling preventive treatment only in patients who really require it.

Government effectiveness and child development in low-middle income countries: COVID-19 pre-pandemic time / Efectividad del gobierno y desarrollo infantil en países de ingresos bajos-medianos: período previo a la pandemia COVID-19

ABSTRACT Introduction: The effect of the COVID- 19 pandemic on the development of children is still uncertain; therefore, it is essential to estimate their development status in the time before the pandemic. The sustainable development goals favor all the resources and strategies to stimulate early childhood development. Government effectiveness is the central axis of developing such actions, policies, and procedures. Methods: We used the early child development module and index from national health surveys (MICS) of 33 countries to calculate the children on track. We also use the World Bank Governance Index, specifically the effective governance score. In addition, we carry out analysis with ArcGIS and GeoDa software to evaluate geographic correlations between the variables studied and identify geographic patterns of child development levels and effective governance. Pearson and Spearman correlation tests were performed in Stata 15.1 software. Results: We studied children from 33 low and middle-income countries; from 7 world regions. Thailand (91.1%) and Turkmenistan (90.7%) have the highest percentages of child development and the lowest in Burundi (39.6%). The lowest value on GE estimate is in Burundi (-1.3), and the highest in the Democratic Republic of Korea (1.0). In the GE Rank, the highest values are again in Korea (82.1%), and the lowest in Haiti (0.9%). The correlation grade between ECDI and GE Estimate was moderate positive (0.522, P-0.001, Correlation Spearman test), similarly to (0.518, P-0001, Pearson correlation test). The general spatial pattern prevails that the African regions present low government effectiveness and early child development scores, positively correlated in this study. Conclusions: With the most up-to-date data reported by countries, it is possible to establish the level of child development before 2019, the year in which the COVID-2019 pandemic began. Studies must be carried out during and after the pandemic to develop the direct and indirect damage received by children in the dimensions of development, in which the government response is decisive.

Resumen Introducción: El efecto que tendrá la pandemia de COVID- 19 en el desarrollo de los niños aún es incierto, por lo que es importante estimar su estado en el tiempo anterior a la pandemia. Los objetivos de desarrollo sostenible exigen favorecer todos los recursos y estrategias para estimular el desarrollo de la primera infancia. La efectividad del gobierno es el eje central del desarrollo de tales acciones, políticas y estrategias en todos los países, especialmente en los países de ingresos bajos y medianos. Métodos: se usó El módulo de desarrollo infantil temprano y el índice de las encuestas nacionales de salud (MICS) de 33 países, para calcular los niños que van por buen camino en su desarrollo. También se utilizó el Índice de Gobernanza del Banco Mundial, específicamente el puntaje de Gobernanza Efectiva. Además, se realizaron análisis con el software ArcGIS y GeoDa para evaluar correlaciones geográficas entre las variables estudiadas e identificar patrones geográficos de niveles de desarrollo infantil y gobernabilidad efectiva. Las pruebas de correlación de Pearson y Spearman se realizaron en el software Stata 15.1. Resultados: Se estudiaron niños de 33 países de ingresos bajos y medios; de 7 regiones del mundo. Tailandia (91,1%) y Turkmenistán (90,7%) tienen los porcentajes más altos de desarrollo infantil y Burundi el más bajo (39,6%). Según la estimación de GE, el valor más bajo se encuentra en Burundi (-1,3) y el más alto en la República Democrática de Corea (1). En el GE Rank, los valores más altos se encuentran en Corea con 82,1% y los más bajos en Haití (0,9%). El grado de correlación entre el ECDI y la estimación de GE fue positivo moderado (0,522, P-0,001, prueba de correlación de Spearman), similar (0,518, P-0001, prueba de correlación de Pearson). El patrón espacial general que prevalece es que las regiones africanas presentan un puntaje bajo de efectividad del gobierno y desarrollo infantil temprano, que se correlacionan positivamente en este estudio. Conclusiones: Con los datos más actualizados reportados por los países sobre desarrollo infantil, se pudo establecer el nivel de desarrollo infantil antes de 2019, año en que comenzó la pandemia de COVID-2019. Es crucial que se realicen estudios durante y después de la pandemia con el objetivo de establecer los daños directos e indirectos que reciben los niños en las dimensiones del desarrollo, en las que la respuesta del gobierno es determinante.

Síndrome de Wilkie / Managment of a Patient with a Diagnosis of Wilkie Syndrome

Introducción: El síndrome de Wilkie es una causa infrecuente de obstrucción intestinal alta, debido a una compresión del duodeno entre la aorta abdominal y la arteria mesentérica superior, de diagnóstico preoperatorio difícil. El estudio baritado y la arteriografía son las pruebas diagnósticas por excelencia. Se ha invocado un manejo conservador en individuos con poco tiempo de evolución. Sin embargo, aquellos con enfermedad crónica habitualmente requieren corrección por medio de la intervención quirúrgica. Objetivo: Exponer el tratamiento de un paciente con diagnóstico de síndrome de Wilkie. Caso clínico: Masculino de 57 años con síndrome emético y pérdida ponderal más de 3 meses de evolución. La gastroduodenoscopia mostró dilatación de la segunda porción duodenal por probable comprensión extrínseca y la serie contrastada reveló stop a nivel de la unión duodenoyeyunal. Se realizó una duodenoyeyunostomía latero-lateral transmesocólica, sin drenaje de vecindad con evolución favorable. Conclusiones: Un alto índice de sospecha se requiere para un diagnóstico acertado de esta entidad. La duodenoyeyunostomía es el proceder quirúrgico que ofrece mejores resultados(AU)

Introduction: Wilkie syndrome is a rare cause for upper intestinal obstruction, due to a compression of the duodenum between the abdominal aorta and the superior mesenteric artery, of difficult preoperative diagnosis. Barium study and arteriography are the gold-standard diagnostics. Conservative management has been preferred in individuals with short time of evolution. However, those with chronic disease usually require correction by surgical intervention. Objective: To present the management of a patient diagnosed with Wilkie syndrome. Case report: A 57-year-old male patient with emetic syndrome and weight loss of more than three months of evolution. Gastroduodenoscopy showed dilatation of the second duodenal portion due to probable extrinsic compression, while the contrast series revealed stop at the duodenojejunal junction. A transmesocolic latero-lateral duodenojejunostomy was performed, without neighboring drainage and with favorable evolution. Conclusions: A high index of suspicion is required for an accurate diagnosis of this entity. Duodenojejunostomy is the surgical procedure that offers the best outcomes(AU)

Antibacterial and hemolytic activity of extracts and compounds obtained from epicarps and seeds of Garcinia madruno(Kunth) Hammel / Actividad antimicrobiana y hemolítica de extractos y compuestos obtenidos del epicarpio y las semillas de Garcinia madruno (Kunth) Hammel

This paper describes the evaluation of the antimicrobial and hemolytic activity of the hexane, dichloromethane, ethyl acetate and methanol extracts from seeds and epicarps of Garcinia madruno; as well garcinol, morelloflavone and volkensiflavone isolated from the same species. In the preliminary test of bacterial susceptibility, hexane extracts from seeds and epicarps and the three compounds tested only displayed inhibitory growth effect against Gram-positive bacteria. The minimum inhibitory concentrations of extract and compounds ranging from 86.6 to 1253.4 µg/mL. The hemolytic activity was assessed; however, except for the methanol extract from seeds, none of the samples studied induced hemolysis. Thus, our results suggest that extracts and compounds from G. madruno have the potential to be used in the control of pathologies associated to Gram-positive bacteria. This is the first report of the antimicrobial and hemolytic activity of extracts of different polarity obtained from seeds and epicarps of this edible species.

El presente artículo describe la evaluación de la actividad antimicrobiana y hemolítica de los extractos de hexano, diclorometano, acetato de etilo y metanol, obtenidos de la semilla y el epicarpio de Garcinia madruno; así como de garcinol, morelloflavona y volkensiflavona; aislados de la misma especie. En el ensayo de susceptibilidad bacteriana, tanto el extracto de hexano obtenido a partir de la semilla y el epicarpio, y los tres compuestos aislados, únicamente mostraron actividad inhibitoria del crecimiento contra bacterias Gram-positivas. La concentración mínima inhibitoria presentó valores entre 86.6 y 1253.4 µg/mL. También se estableció la actividad hemolítica; sin embargo, con excepción del extracto metanólico obtenido a partir de las semillas, ninguna de las muestras evaluadas indujo hemólisis. Por lo tanto, los resultados sugieren que los extractos y compuestos de G. madruno tienen el potencial de ser usados en el control de bacterias Gram-positivas asociadas a diversas patologías. Este es el primer reporte de actividad antimicrobiana y hemolítica de extractos de diferente polaridad obtenidos de las semillas y epicarpios de esta especie comestible.

Performance of Soybean Seedlings Upon Nutrient Application by Seed Coating

ABSTRACT The aim of this study was to evaluate the effect of different seed coatings consisting of various combinations of three nutrients (calcium, magnesium and silicon) on two soybean cultivars (BRS 243 RR and CD 233 RR). Dolomitic limestone and aluminum silicate were chosen as the nutrient sources. Leaf area, plant height, shoots dry matter, crop growth rate, relative growth rate and net assimilation rate were the studied variables, evincing that the seed coating that comprised calcium, magnesium and silicon led to better performance in terms of growth rates 30 days after emergence. Significant differences in the response to the seed coatings were also observed between the two studied soybean genotypes.
