Defining an ageing-related pathology, disease or syndrome: International Consensus StatementNARA Subscribed
Around the world, individuals are living longer, but an increased average lifespan does not always equate to an increased health span. With advancing age, the increased prevalence of ageing-related diseases can have a significant impact on health status, functional capacity and quality of life. It is therefore vital to develop comprehensive classification and staging systems for ageing-related pathologies, diseases and syndrom...
Purpose of Review Environmental chemical exposures may disrupt child development, with long-lasting health impacts. To date, U.S. studies of early environmental exposures have been limited in size and diversity, hindering power and generalizability. With harmonized data from over 60,000 participants representing 69 pregnancy cohorts, the National Institutes of Health’s Environmental influences on Child Health Outcomes (ECHO) P...
Rationale Major depressive disorder (MDD) is a leading cause of disability worldwide but currently prescribed treatments do not adequately ameliorate the disorder in a significant portion of patients. Hence, a better appreciation of its aetiology may lead to the development of novel therapies. Objectives In the present study, we have built on our previous findings indicating a role for protease-activated receptor-2 (PAR2) in s...
Common, low-frequency, rare, and ultra-rare coding variants contribute to COVID-19 severityNARA Subscribed
The combined impact of common and rare exonic variants in COVID-19 host genetics is currently insufficiently understood. Here, common and rare variants from whole-exome sequencing data of about 4000 SARS-CoV-2-positive individuals were used to define an interpretable machine-learning model for predicting COVID-19 severity. First, variants were converted into separate sets of Boolean features, depending on the absence or the pr...
Regulation of host‐infection ability in the grass‐symbiotic fungus Epichloë festucae by histone H3K9 and H3K36 methyltransferasesNARA Subscribed
Summary Recent studies have identified key genes that control the symbiotic interaction between Epichloë festucae and Lolium perenne . Here we report on the identification of specific E. festucae genes that control host infection. Deletion of setB , which encodes a homologue of the H3K36 histone methyltransferase Set2/KMT3, reduced histone H3K36 trimethylation and led to severe defects in colony growth and hyphal development....
Epichloe novae‐zelandiae , a new endophyte from the endemic New Zealand grass Poa matthewsiiNARA Subscribed
Epichloe endophytes (Clavicipitaceae) infect pooid grass genera worldwide but predominantly in the Northern Hemisphere, but appear to be rare in native grasses of the Southern Hemisphere. Because of benefits that hosts may receive from the symbiosis, Epichloe endophytes have been extensively studied and are considered important components of sustainable agriculture. There are only a few studies available on the incidence of en...
Summary Peramine is a non‐ribosomal peptide‐derived pyrrolopyrazine (PPZ)‐containing molecule with anti‐insect properties. Peramine is known to be produced by fungi from genus Epichloë , which form mutualistic endophytic associations with cool‐season grass hosts. Peramine biosynthesis has been proposed to require only the two‐module non‐ribosomal peptide synthetase (NRPS) peramine synthetase (PerA), which is encoded by the 8.3...
Assessing ecological correlates of marine bird declines to inform marine conservationNARA Subscribed
Identifying drivers of ecosystem change in large marine ecosystems is central for their effective management and conservation. This is a sizable challenge, particularly in ecosystems transcending international borders, where monitoring and conservation of long‐range migratory species and their habitats are logistically and financially problematic. Here, using tools borrowed from epidemiology, we elucidated common drivers under...
