Comparative effect of the fungicide Prochloraz-Mn on Agaricus bisporus vegetative-mycelium and fruit-body cell walls

Fungicides to control mycopathogens of commercial Agaricus bisporus, a mushroom cultivated for human consumption, are a major field of study, since these chemicals are toxic to both the host and its fungal parasites. The fungicide Prochloraz-Mn, used at its LD50 for A. bisporus, partially inhibited protein biosynthesis in the vegetative mycelial cell walls of this mushroom and caused significant changes in cell-wall polysaccharide structure, as deduced by methylation analysis and gas liquid chromatography-mass spectrometry (GLC-MS). Furthermore, the aggregated mycelial walls showed distinct alterations in their overall chemical composition following the administration of Prochloraz-Mn at the LD50 and the LD50 ×1000. As expected, GLC-MS studies indicated that the latter dose caused more appreciable differences in polysaccharide structure. The decrease in mushroom crop yields obtained from industrial cultures treated with Prochloraz-Mn to control V. fungicola infection depended on the dose of the fungicide employed, whereas fruit-body morphology was only slightly affected at the highest Prochloraz-Mn concentration used.

From the Body to the City: Rethinking Our Territories from Collective Research with Social Cartography

[ES] En tiempos urbanos nuestros cuerpos han sido desconectados de su medio natural. Nuestros hogares han invisibilizado desigualdades estructurales. Nuestra individualidad ha roto lazos comunitarios y poco a poco hemos perdido nuestra capacidad de actuar para el bien común. Ante tal escenario, es necesario desarrollar metodologías innovadoras desde procesos de investigación colectiva capaces de reconectar a las futuras generaciones con las problemáticas y desigualdades de nuestros territorios. Somos territorio y el territorio es el reflejo de las personas que somos. En este sentido, el presente artículo pretende explorar la experiencia de innovación pedagógica desarrollada desde la investigación colectiva con cartografía social junto con el alumnado de 4º de Primaria del ceip Vicente Gaos de la ciudad de Valencia. El proceso es una iniciativa piloto impulsada por el Instituto de Gestión de la Innovación y del Conocimiento ¿ Ingenio (csic ¿ upv) y la maestra tutora de la clase, que han participado activamente en el co-diseño y facilitación de la cartografía social. La experiencia pretende conectar al alumnado con el territorio, desde la reflexión-acción sobre sus propios cuerpos, hogares y ciudad, con el fin de facilitar el desarrollo de habilidades, aptitudes y capacidades para el ejercicio del derecho a la ciudad hacia el desarrollo humano y sostenible.[EN] En temps urbans els nostres cossos han estat desconnectats del seu medi natural.

Our homes have made structural inequalities invisible. Our individuality has broken community ties, and we have gradually lost our ability to act for the common good. Given this scenario, innovative methodologies must be developed from collective research processes that can reconnect future generations with the problems and inequalities of our territories. We are territory and the territory is the reflection of the people we are. The present article follows this line to explore the experience of a pedagogical innovation developed through collective research using social mapping with year 4 pupils at the Vicente Gaos infant and primary school in Valencia. The process is a pilot initiative promoted by the Institute for Innovation and Knowledge Management - Ingenio (csic - upv) and the class tutor, who played an active part in co-designing and facilitating the social mapping project. The aim of the experience is to connect the students with the territory, by reflection-action on their own bodies, homes and city, to facilitate the development of skills, aptitudes and capacities with which to exercise the right to the city and promote human and sustainable development.Leivas-Vargas, M.; Boni Aristizábal, A.; Mendoza Crespo, M.

Trends in the medical repatriation of Filipino seafarers: a ten year study of a Philippine maritime shipping company (OSM Maritime)

Background: Seafarers, confronted with unique health challenges, occasionally necessitate medical repatriation.This study examines the trends in medical repatriation cases among Filipino seafarers employedby OSM Maritime shipping company over a 10-year period from 2013 to 2022.Materials and methods: Medical records of OSM Maritime seafarers were reviewed, obtaining causes forand dates of medical repatriation. International Classification of Diseases (ICD-11) was utilised to classifyrepatriation cases. Proportion of repatriation cases were calculated and their annual trends were analysed.Results: Our findings reveal that the majority of repatriation cases are attributed to injury/trauma (19.91%),musculoskeletal (18.40%), gastrointestinal (16.56%), cardiovascular (8.77%), infectious (6.82%),and genitourinary conditions (5.30%). Significantly, the study identifies a declining trend in the proportionof cardiovascular, gastrointestinal, and genitourinary conditions in annual repatriation cases, particularlyin ischaemic heart conditions, cholelithiasis, cholecystitis, and urinary calculus.Conclusions: These results emphasize the critical need for multisectoral collaboration to enhance seafarers’health and well-being. Prioritizing comprehensive care programmes, ensuring safe working conditions,and exploring holistic healthcare initiatives are essential steps to enhance seafarers’ occupational health

Although xylem embolism resistance thresholds (for example, Ψ50) and hydraulic safety margins (for example, HSM50) are important predictors of drought-induced mortality risk3-5, little is known about how these vary across Earth's largest tropical forest. Here, we present a pan-Amazon, fully standardized hydraulic traits dataset and use it to assess regional variation in drought sensitivity and hydraulic trait ability to predict species distributions and long-term forest biomass accumulation. Parameters Ψ50 and HSM50 vary markedly across the Amazon and are related to average long-term rainfall characteristics. Both Ψ50 and HSM50 influence the biogeographical distribution of Amazon tree species. However, HSM50 was the only significant predictor of observed decadal-scale changes in forest biomass. Old-growth forests with wide HSM50 are gaining more biomass than are low HSM50 forests. We propose that this may be associated with a growth-mortality trade-off whereby trees in forests consisting of fast-growing species take greater hydraulic risks and face greater mortality risk. Moreover, in regions of more pronounced climatic change, we find evidence that forests are losing biomass, suggesting that species in these regions may be operating beyond their hydraulic limits. Continued climate change is likely to further reduce HSM50 in the Amazon6,7, with strong implications for the Amazon carbon sink.Publisher PDFPeer reviewe

Fungal Systematics and Evolution: FUSE 8

In this 8th contribution to the Fungal Systematics and Evolution series published by Sydowia, the authors formally describe 11 species: Cortinarius caryae, C. flavolilacinus, C. lilaceolamellatus, C. malodorus, C. olivaceolamellatus, C. quercophilus, C. violaceoflavescens, C. viridicarneus, Entoloma meridionale (Agaricales), Hortiboletus rupicapreus (Boletales), and Paraglomus peruvianum (Paraglomerales). The following new country records are reported: Bolbitius callistus (Agaricales) from Russia and Hymenoscyphus equiseti (Helotiales) from Sweden. Hymenoscyphus equiseti is proposed as a new combination for Lanzia equiseti, based on ITS and LSU sequence data in combination with morphological study

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults

Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For schoolaged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference) and obesity (BMI >2 SD above the median). Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining underweight or thinness. Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesit
