The mode of action, bioaccumulation potential and toxicity of Rare Earth Elements (REE), with several applications in the technology, medical and agricultural fields, are still understudied. The nitrates acute effects on single exposures, binary and ternary mixtures of lanthanum (La), neodymium (Nd) and samarium (Sm) on Lactuca sativa lettuce seed germination and wet biomass in an artificial soil (AS) and an Ultisol were assessed. Germination (EC), wet biomass (IC) and germination inhibition (% GI) were evaluated. EC values show La was the most toxic in Ultisol, Sm in AS, and Nd appears with intermediate values on both substrates. The IC, both single and mixed, decreased from 3- to 181-fold with increasing test concentrations in relation to the control in AS, while increases in Ultisol were observed, followed by decreases at higher doses which may be associated with the low-dose stimulation effect (hormesis). Our findings may be used to subsidize REE risk assessment studies and reinforce the hormesis effect to prevent the use of high application of REE fertilizers, avoiding the accumulation of REE in agricultural soils.

Visual perspective taking often involves transitioning between perspectives, yet the cognitive mechanisms underlying this process remain unclear. The current study draws on insights from task- and language-switching research to address this gap. In Experiment 1, 79 participants judged the perspective of an avatar positioned in various locations, observing either the rectangular or the square side of a rectangular cube hanging from the ceiling.

Setting: Despite Canada's single-payer health system, marginalized populations often experience poor health outcomes and barriers to healthcare access. In response, mobile health clinics (MHCs) have been deployed in several cities across Canada. MHCs are well established in the United States; however, little is known about their role and impact in a country with universal healthcare.

Proximity labeling (PL) has emerged as a powerful technique for the in situ elucidation of biomolecular interaction networks. However, PL methods generally rely on single-biological-hierarchy control of spatial localization at the labeling site, which limits their application in multi-tiered biological systems. Here, we introduced another enzymatic reaction upstream of an enzyme-based PL reaction and targeted the two enzymes to markers indicating different biological hierarchies, establishing a two-level spatially localized proximity labeling (P2L) platform for in situ molecular measurement and manipulation.

Background: Thinking Healthy Programme (THP) is an evidence-based psychosocial intervention that can be delivered by non-psychologists and does not require the implementer to have a mental health background or field experience. The THP has been tested in maternal health in many countries. However, the application of the THP model in Chinese maternal and child health has not been reported.
