Isatin–pyridine oxime hybrids as potential reactivators of A-242-inhibited acetylcholinesteraseNARA Subscribed
Three new isatin–pyridine-2-oxime hybrids (AM01–03) were synthesized and experimentally evaluated as reactivators of acetylcholinesterase (AChE) inhibited by a surrogate of the nerve agent A-242, in comparison with their 4-oxime isomers previously reported by our research group. Furthermore, the interactions of these molecules within the AChE/A-242 complex were assessed through docking and molecular dynamics (MD) simulations....
Atta robusta is a narrow endemic leaf-cutting ant restricted to restinga habitats along Brazil’s southeastern coast. Despite its conservation status, little is known about its evolutionary history and genetic structure. Here, we investigate patterns of genetic variation in A. robusta using mitochondrial (COI–IGS–tRNALeu–COII) and nuclear (EF1alpha copy one) DNA markers sampled across its known range. We assess genetic diversit...
Diversity of terpenoids in arthropod–plant interactionsNARA Subscribed
Terpenoids are among the most diverse and abundant classes of plant secondary metabolites, with over 134,000 structures identified to date across green plants. In addition to plants, numerous microorganisms and animals, including arthropods, can synthesise terpenoids. All terpenoids are derived from the 5-carbon isoprene units. These compounds play crucial roles in mediating interactions between plants and arthropods and funct...
A metabolomic clock of population ageing: cross-cohort validation and associations with frailty and cognitive functionNARA Subscribed
Understanding the links between metabolism, ageing, and age-related phenotypes may clarify the role of ageing in disease onset and improve risk prediction. We conducted a cross-cohort assessment of biological age using broad-spectrum LC–MS metabolomics of 3,686 plasma samples in 2,295 participants, aged 20–89, from the UK Airwave study ( N = 960) and the Irish Longitudinal Study of Ageing ( N = 1,335). The nucleoside N 2 ,N 2...
Ascophyllum nodosum extract modulates the antioxidant response of olive cultivars to water deficit stressNARA Subscribed
Aligned with the Green Deal strategy to reduce the impacts of climate change on the agri-food sector, this study assessed the potential of a commercial biostimulant based on Ascophyllum nodosum extract to improve olive tolerance to drought. Potted plants of Olea europaea (cultivars Arbequina and Galega) were pre-treated with the extract or water. One group was maintained at 100% field capacity and another under water-deficit (...
Codium tomentosum is currently cultivated through vegetative propagation (cuttings) in tumble culture systems targeting niche markets. To scale up and expand its aquaculture production, optimization of propagation and culture methods is key. In Asia, artificial seed production via regeneration of isolated utricles and medullary filaments has already been established for the commercial production of Codium fragile . Our prelimi...
Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...
Soil Microbial Diversity and Network Organization Respond to Land Use and Agricultural Inputs WorldwideNARA Subscribed
Soil microbiomes are critical for ecosystem functioning, yet the global influences of climate and agricultural practices on their diversity and structure remain incompletely characterized. Here we analyzed 1921 soil samples from 33 countries worldwide across diverse biomes to assess how climate gradients and agricultural inputs, including pesticides and fertilizers, shape prokaryotic and fungal communities. We found that micro...
Detection and mitigation of Paraphysomonas sp., a chrysophycean responsible for the collapse of industrial Tisochrysis lutea culturesNARA Subscribed
Microalgae are increasingly recognized as a sustainable resource to address challenges associated with climate change and population growth, owing to their capacity to produce high-quality biomass for applications in feed, food, and cosmeceuticals. However, the expansion of microalgae-based industries remains constrained by harmful biological contaminants (HBCs), which can rapidly reduce productivity, often signalled by visibl...
Phytoremediation for indoor air quality (IAQ) improvement: removal efficiency of formaldehyde by epiphytic TillandsiaNARA Subscribed
Formaldehyde (FA) is a high-priority indoor pollutant with proven adverse effects on human health. Recent preliminary evidence has demonstrated that epiphytic Tillandsia plants can uptake airborne pollutants directly from the gas-phase. This study aims to further investigate on the phytoremediation potential of two Tillandsia species, T. velutina and T . ionantha , specifically focusing on their efficiency in removing FA. To c...
