Pesticides are among the most effective tools for pest control; however, their use involves significant exposure to toxic agents, and their use implies significant risks to human health and the environment. The present scientometric analysis and systematic review highlight the genotoxic and cytotoxic effects of pesticides with Organophosphates and Neonicotinoids being among the most relevant classes studied, which are linked mainly to mechanisms such as oxidative stress and DNA damage in human, animal and plant cells. Through biomarkers and standardized techniques such as comet and micronucleus assays, the correlation of these compounds in the generation of mutations and genetic alterations has been confirmed, with critical implications for public and environmental health. Additional research has evolved toward more precise approaches conducted by international collaboration and a special interest in emerging countries. This study highlights the need for stricter regulation, the development of less toxic pesticides considering other alternatives such as biopesticides, strategies to mitigate associated risks, and the establishment of a solid foundation for future research and sustainable policies.

This paper reports an advanced statistical physics modeling to elucidate the adsorption process of two relevant pharmaceuticals, namely amoxicillin (AMOX) and imipramine (IMP), on aluminum-pillared clay. A double-layer model was used to interpret the adsorption mechanism of these pharmaceuticals at 298–318. This model indicated the presence of molecular aggregation for IMP adsorption via the formation of dimers or trimers, and a monomolecular AMOX separation process. The removal of both compounds was endothermic, showing better adsorption capacity for IMP (82 mg/g) than for AMOX (37 mg/g). Calculated adsorption energies (ΔE1, ΔE2 < 40 kJ/mol) confirmed a physisorption mechanism, which may be governed by hydrogen bonding due to the adsorbent chemistry and adsorbate molecular structure. Configurational entropy and free enthalpy were calculated to analyze the thermodynamics of AMOX and IMP adsorption equilibria. These thermodynamic functions confirmed the molecular disorder during adsorption and system’s spontaneity. This study contributes with new theoretical findings for unraveling complex adsorption mechanisms, at the molecular level, of pharmaceutical molecules, with the aim of intensifying water depollution systems.

A gossypiboma (GPB), also referred to as a textiloma (TXT), is a mass formed as a result of the body’s inflammatory and granulomatous response to retained surgical textile material (RSTM), most commonly gauze or mesh fibers. Its reported incidence ranges from 1 in 1,000 to 1 in 10,000 surgical procedures, although the true frequency is believed to be significantly higher due to underreporting related to medicolegal concerns. This entity is clinically important because it may mimic more common postoperative complications such as abscess (ABS), seroma (SER), or mesh infection (MI), frequently leading to diagnostic delay and unnecessary morbidity.The purpose of this report is to present an uncommon instance of mesh-associated textiloma (MAT) following ventral hernia repair with polypropylene mesh (PPM) and to highlight its radiologic, histopathologic, and clinical features that allow differentiation from other postoperative collections.A 39-year-old female patient with a history of ventral hernia underwent surgical repair with mesh implantation. Postoperatively, she developed persistent umbilical discharge and, three months later, progressive abdominal fluid leakage. Contrast-enhanced computed tomography (CECT) revealed a well-defined hypodense intraperitoneal collection measuring 80 × 64 × 40 mm with a fistulous tract (FT) extending to the abdominal wall, without evidence of systemic inflammatory dissemination. These features, particularly the encapsulated nature of the collection and the organized fistulization pattern, were highly suggestive of a chronic foreign-body reaction (FBR) rather than an acute ABS, which typically presents with diffuse inflammatory infiltration, or MI, which is associated with diffuse mesh thickening and surrounding cellulitis.A second surgical exploration was performed, and the resected specimen underwent histopathological examination (HPE), which demonstrated foreign-body granulomatous inflammation (FBGI) with multinucleated giant cells (MGC) surrounding textile fibers embedded in fibrous tissue, consistent with MAT, and without evidence of dysplasia or malignancy. Following complete excision and aponeurotic closure, the patient recovered uneventfully, with no recurrence during follow-up.This case reinforces that MAT should be included in the differential diagnosis of persistent postoperative collections after mesh-based hernia repair and demonstrates that characteristic CECT findings combined with timely surgical management are essential to reduce morbidity and prevent long-term complications.

ABSTRACT This study investigates the impact of production systems, including: (1) open production system (OP) and (2) vertical farm (VF) on lettuce quality. The study aligns with SDG 2 (Zero Hunger) and SDG 12 (Responsible Consumption and Production). Germination experiments were carried out inside a climate‐controlled farm for 4 weeks with two varieties of lettuces: Ruby Sky Lettuce (LR) and Patrona Lettuce (LO). Then, seedlings were planted in two experimental settings: an open production system (OP) with a dripping irrigation system and a vertical farm treatment (VF) with an aero hydroponic irrigation system arrangement with a 200 L nutrient tank. A comparison test was carried out between Patrona Lettuce (LO) and Ruby Sky Lettuce (LR), which were harvested in two different production systems. The two lettuce varieties, Ruby Lettuce (RL) and Patrona Lettuce (PL), were sampled for microbiological analysis and counts using the following quality indicators: aerobic mesophilic microorganisms, coliforms, fungi, and yeast to compare the production systems. Microbial analysis revealed significantly lower counts of aerobic mesophilic microorganisms, coliforms, and fungi in vertical lettuce. For Ruby Sky, outdoor production resulted in 29‐, 32‐, and 37‐times higher counts, respectively. Patrona exhibited similar trends. These findings suggest that vertical farming enhances food safety by minimizing microbial contamination. VF can empower small‐scale farmers, improve agricultural productivity, and enhance food security, particularly in regions facing limited land and water resources, thus reaching towards SDG 2 and SDG 12.

Mycelium-based composites (MBCs) are organic materials that could replace expanded polystyrene (EPS) in various applications. In Mexico, prefabricated lightweight vaults used in roofing systems offer a cost-effective, time-efficient alternative for housing. This system is important for low-income groups due to its affordability and quick installation without specialized tools. The research compares the strength, water absorption, and fire resistance of MBCs made with the fungal species Pleurotus ostreatus, Pleurotus djamour, and Ganoderma lucidum, using substrates such as sawdust, straw, and coconut fiber, against commercial EPS. Results show 80% of MBC samples had higher compressive strength, up to 1200 kPa with Ganoderma and 171 kPa with P. ostreatus, without mechanical or hot pressing. All MBC samples exhibited a higher elastic modulus, ignited 30 times slower under heat, but had a density 20 times greater than EPS.

El presente trabajo se desarrolla una propuesta didáctica que tiene como objetivo fortalecer el pensamiento matemático y computacional en los estudiantes, favoreciendo la vinculación entre las matemáticas y la vida cotidiana. La propuesta utiliza escenarios elaborados en GeoGebra donde se ponen en juego elementos geométricos y algebraicos para construir el concepto de combinación, el cual se utiliza como base para aplicarlo posteriormente en el análisis de los diferentes recorridos posibles entre dos puntos mediante la métrica del taxista. Este enfoque permite que los estudiantes comprendan cómo las matemáticas modelan situaciones reales de desplazamiento urbano. La propuesta se fundamenta en la metodología del Aprendizaje Basado en Problemas (ABP), que promueve una participación activa y el desarrollo de aprendizajes significativos. En relación con los principios de la Nueva Escuela Mexicana (NEM), se busca fomentar la autonomía en el aprendizaje y el pensamiento crítico a partir de situaciones contextualizadas. El uso de GeoGebra potencia la exploración y la formulación de conjeturas, aspectos esenciales para el desarrollo del pensamiento matemático.

This study reports the design, fabrication, and optical characterization of stereolithography-printed waveguides doped with graphite and zinc oxide (ZnO). Effective refractive indices were predicted using the Bruggeman effective medium approximation and experimentally validated. The doped structures exhibited total internal reflection and were evaluated as optofluidic sensors for detecting variations in alcoholic beverages and telomeric DNA concentrations. Raman spectroscopy further confirmed molecular discrimination between male and female samples. The results demonstrate a reproducible approach for producing low-cost, application-specific optical waveguides suitable for chemical and biological sensing platforms, with tunable performance enabled through dopant selection.
