Abstract:
... Vitamin D supplementation during pregnancy has been studied since the early 1980′s and, while many clinical trials have been performed, we remain at a crossroads in our conclusions about vitamin D’s effects during pregnancy and the optimal dose and timing of supplementation [...] ...

Abstract:
... The demands for genuine remediation of heavy metal contaminated soil have triggered extensive studies in the soil washing method. However, numerous soil washing methods show poor sustainability for target soil, due to the tremendous cost, hidden secondary pollution and severe soil deterioration. Here, an asymmetrical alternating current electrochemically-mediated remediation platform (ACRP) is dev ...

Abstract:
... MAIN CONCLUSION: Peptide-receptor complexes activate distinct downstream regulatory networks to mediate plant adaptions to abiotic environmental stress. Plants are constantly exposed to various adverse environmental factors; thus they must adjust their growth accordingly. Plants recruit small secretory peptides to adapt to these detrimental environments. These small peptides, which are perceived b ...

Abstract:
... Health researchers may struggle to choose suitable validated dietary assessment tools (DATs) for their target population. The aim of this review was to identify and collate information on validated UK DATs and validation studies for inclusion on a website to support researchers to choose appropriate DATs. A systematic review of reviews of DATs was undertaken. DATs validated in UK populations were ...

Abstract:
... High‐phenotypic plasticity has long been considered as a characteristic promoting exotic plant invasions. However, the results of the studies testing this hypothesis are still inconsistent. Overlooking the effects of species resource requirements and environmental resource availability may be the main reasons for the ambiguous conclusions. Here, we compared phenotypic plasticity between five noxio ...

Abstract:
... Plastic products are widely used around the world, but waste plastic is not reasonably managed and causes serious plastic pollution. Biodegradable plastics (BPs) provide an alternative to conventional plastics, but not all BPs can be completely degraded under natural conditions. Instead, they may break down into microplastics (MPs) faster than conventional plastics, posing an additional threat to ...

Abstract:
... This study provides the first contribution to the knowledge of the non-calcareous grasslands of the arenaceous sector of the Monti Sibillini National Park (central Italy). We conducted 55 relevés using the Braun-Blanquet phytosociological method and analysed the ecology of plant communities by Redundancy analysis using topographic variables and Ellenberg Indicator Values as predictors. We identifi ...
... The transformation of natural habitats into cropland is a major issue in ecological conservation. Of particular concern is the large-scale biotic homogenization (reduced β-diversity) of soil microbial communities. Paddy fields represent the largest anthropogenic ecosystem in the world; however, bacterial homogenization and reduced biodiversity in paddy fields caused by intensive modern agricultura ...

... In addition to their central functions in translation, ribosomes can adopt inactive structures that are fully assembled yet devoid of mRNA. We describe how the abundance of idle eukaryotic ribosomes is influenced by a broad range of biological conditions spanning viral infection, nutrient deprivation, and developmental cues. Vacant ribosomes may provide a means to exclude ribosomes from translatio ...

Abstract:
... Iron (Fe) is an essential element for almost all living organisms. In addition, microbial Fe cycling drives the biogeochemical cycles of other elements, although little is known about characteristics of Fe cycling and its driving mechanism in desert ecosystems. Here, we investigated the key microbial functional genes involved in Fe(II) oxidation and Fe(III) reduction and the associated factors aff ...
... PURPOSE: Plants growing in the soils of karst forests associate with arbuscular mycorrhizae (AM) or ectomycorrhizae (ECM) to acquire nutrients. We researched how these different mycorrhizal associations affect rhizosphere soil nutrient economy in these calcareous soils. METHODS: Bulk and rhizosphere soils were sampled beneath 25 AM and 9 ECM plants growing in primary forests at the Puding Karst Cr ...
