Non-invasive brain stimulation (NIBS) has gained increasing popularity as a modulatory tool for drawing causal inferences and exploring task-specific network interactions. Yet, a comprehensive synthesis of reading-related NIBS studies is still missing. We fill this gap by synthesizing the results of 78 NIBS studies investigating the causal involvement of brain regions for reading processing, and then link these results to a neurobiological model of reading. The included studies provide evidence for a functional-anatomical double dissociation for phonology versus semantics during reading-related processes within left inferior frontal and parietal areas. Additionally, the posterior parietal cortex and the anterior temporal lobe are identified as critical regions for reading-related processes. Overall, the findings provide some evidence for a dual-stream neurobiological model of reading, in which a dorsal stream (left temporo-parietal and inferior frontal areas) processes unfamiliar words and pseudowords, and a ventral stream (left occipito-temporal and inferior frontal areas, with assistance from the angular gyrus and the anterior temporal lobe) processes known words. However, individual differences in reading abilities and strategies, as well as differences in stimulation parameters, may impact the neuromodulatory effects induced by NIBS. We emphasize the need to investigate task-specific network interactions in future studies by combining NIBS with neuroimaging.Phosphorus (P) is a critical macronutrient that is essential for many life-sustaining processes. Despite decades of work on plant performance under P deficiency and the importance of microbes in ecosystem processes, little is known about how bacterial and fungal flora respond to P gradients and determine the vegetation health. In current study, we examined soil edaphic conditions and microbial communities in 39 untouched natural forests representing phosphorous deficient (Pp) and phosphorus rich (Pr) soils (due to naturally occurring phosphate rocks) in Yunnan Province, China. We also considered the effect of plant functional types by including the dominant tree species. Bacterial and fungal diversity was greater across the Pp sites compared with Pr sites. The relative abundance of Actinobacteria and Gemmatimonadetes was higher across Pp sites, while Chlamydiae and Verrucomicrobia showed the opposite pattern, with greater relative abundance across the Pr sites. Bacterial taxa that were observed in low P soils were more likely having oligotrophic life history strategies. Interestingly, ectomycorrhizal (ECM) fungal diversity was promoted in the Pp sites, indicating that the decreasing soil P concentration and the increasing host P demand foster stimulated the ECM species for hyphal soil exploration. selleck chemicals llc Moreover, the high P level caused saprophytic fungi (SAP) to diverge, causing its enrichment only under Q. variabilis compared to low P soil, where there is no difference in relative abundance of SAP between the two tree species. This likely resulted in an enhanced decomposition process by SAP and elevation of soil properties (Carbon and Nitrogen) under Q. variabilis across the Pr sites. Taken together, our findings highlight the highly diverse microbiome in low P soils. The higher soil P caused shifts of fungal functional guilds, which likely influence tree growth and health (ECM), along with divergence of ecosystem services between tree functional types.We evaluated the potential impacts of atmospheric deposition on marine productivity and inorganic carbon chemistry in the northwestern Pacific Ocean (8-39°N, 125-157°E). The nutrient concentration in atmospheric total suspended particles decreased exponentially with increasing distance from the closest land-mass (Asia), clearly revealing anthropogenic and terrestrial contributions. The predicted mean depositional fluxes of inorganic nitrogen were approximately 34 and 15 μmol m-2 d-1 to the west and east of 140°E, respectively, which were at least two orders of magnitude greater than the inorganic phosphorus flux. On average, atmospheric particulate deposition would support 3-4% of the net primary production along the surveyed tracks, which is equivalent to ~2% of the dissolved carbon increment caused by the penetration of anthropogenic CO2. Our observations generally fell within the ranges observed over the past 18 years, despite an increasing trend of atmospheric pollution in the source regions during the same period, which implies high temporal and spatial variabilities of atmospheric nutrient concentration in the study area. Continued atmospheric anthropogenic nitrogen deposition may alter the relative abundances of nitrogen and phosphorus.Dual modification in which carboxymethyl cellulose (CMC) stabilization and sulfidation are coupled is an effective strategy to solve the insufficient electron selectivity, reactivity, and mobility of nanoscale zerovalent iron (nZVI). We compared the sulfur content, suspension composition, viscosity, zeta potential, and sedimentation of dual-modified nZVI suspensions synthesized in different modification sequences to analyze the interaction among CMC, the sulfidation reagent, and nZVI. The results show that the dissolved CMC does not take up S2-, and the CMC coating on the surface does not block S2- during sulfidation. However, CMC can peel off the FeS shell, resulting in a low sulfur content in nZVI. The Na+ of the sulfidation reagent and the Fe2+ dissolved from the FeS precipitates reduce the CMC viscosity, causing accelerated sedimentation and reduced mobility of nZVI. The peeled off FeS shell increases the free Fe2+ concentration, thereby enhancing nitrobenzene reduction. Additionally, CMC promotes nitrobenzene reduction and hydrogen evolution reactions due to the increased nZVI dispersibility. These findings explain why postsulfidated and one-pot nZVI has higher reactivity and electron selectivity, while presulfidated nZVI has higher mobility. This study highlights the importance of the modification sequence for the dual-modified nZVI properties and provides support for the synthesis method.
