Article Abstract
This study investigated the sorption characteristics of methylphosphonic acid (MPn) on marine sediments, focusing on the effects of sediment composition and environmental factors. The results indicated that MPn showed good stability on sediment samples and physical process was the main fraction for MPn sorption. Light fraction organic matter (LFOM) significantly enhanced the sorption ability of the sediments. The interactions between minerals and OM in sediments reduced MPn retention. Analysis of organic phosphorus (OP) fractions revealed that the OP sorbed by the sediments mainly existed in exchangeable or loosely sorbed organic phosphorus (Ex-OP) and iron/aluminium-bound organic phosphorus (Fe/Al-OP). Environmental factors influenced the sorption of MPn on sediments. Compared with the artificial seawater (ASW), the sorption ability was stronger in the diluted media. The pH affected the forms of MPn and the surface properties of sediments, significantly increasing MPn sorption under high acidic and alkaline conditions, while the electrostatic repulsion at pH = 8 partially inhibited the sorption. Thermodynamic parameters indicated that the MPn sorption was a spontaneous endothermic process.

Background: Children in low- and middle-income countries face obstacles to optimal language and cognitive development due to a variety of factors related to adverse socioeconomic conditions. One of these factors is compromised caregiver-child interactions and associated pressures on parenting. Early development interventions, such as dialogic book-sharing (DBS), address this variable, with evidence from both high-income countries and urban areas of low- and middle-income countries showing that such interventions enhance caregiver-child interaction and the associated benefits for child cognitive and socioemotional development.

Aim: To investigate the phenotypic and genomic features of three multidrug-resistant (MDR) clinical mucoid and non-mucoid uropathogenic Escherichia coli (UPEC) strains to understand their antimicrobial resistance, biofilm formation, and virulence in urinary tract infections (UTIs).
Methods And Results: The UPEC strains A5, A10, and A15 were isolated from two UTI patients. Phenotypic assays included colony morphology, antibiotic susceptibility, motility, and biofilm formation.

While the cancer genome is well-studied, the nongenetic exposome of cancer remains elusive, particularly for regionally prevalent cancers with poor prognosis. Here, by employing a combined knowledge- and data-driven strategy, we profile the chemical exposome of plasma from 53 healthy controls, 14 esophagitis and 101 esophageal squamous cell carcinoma (ESCC) patients, and 46 esophageal tissues across 12 Chinese provinces, integrating inorganic, endogenous, and exogenous chemicals. We first show that components of the ESCC chemical exposome mediate the relationship between ESCC-related dietary/lifestyle factors and clinic health status indicators.
