The main pigment for oxygenic photosynthesis, chlorophyll (Chl) a , is structurally related to several other Chl variants, naturally occurring mostly with mono-oxidized substitutions. These include Chl b , Chl d and Chl f and divinyl chlorophylls (DVChls) a and b . In this contribution, we computationally explore an expanded set of over 250,000 Chl variants, looking for potentially interesting targets for synthetic biology. We...
Plankton communities today and tomorrow—potential impacts of multiple global change drivers and marine heatwavesNARA Subscribed
In the context of global change, marine organisms are subjected not only to gradual changes in abiotic parameters, but also to an increasing number of extreme events, such as heatwaves. However, we still know little about the influence of heatwaves on the structure of marine communities, and experimental studies are needed to test the impact of heatwaves alone and in combination with other environmental drivers. Here, we condu...
New mouse model for inducible hACE2 expression enables to dissect SARS-CoV-2 pathology beyond the respiratory systemNARA Subscribed
The Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection is not limited to the respiratory tract as receptors, including the angiotensin-converting enzyme 2 (ACE2), are expressed across many tissues. This study employed a new conditional mouse model, Rosa26 creERT2/chACE2 , which expresses human ACE2 (hACE2) across multiple organs, to investigate the effects of SARS-CoV-2 infection beyond the respiratory syst...
Microplastic in long-term soil monitoring: first spatial and temporal data on plastics in agricultural topsoilsNARA Subscribed
Purpose Within the emerging field of soil related microplastic (MP) research, little is known about spatio-temporal variations of MP concentrations in soils. To overcome this current knowledge gap, we suggest the exploitation of long-term soil monitoring programmes (LTSM) and its archived soil samples, to gain first data on spatio-temporal variations within soil MP contamination. Methods We analysed 32 archived topsoil samples...
Surface effects on deep-water gravity waves are investigated theoretically by the application of a Robin boundary condition with a complex Robin parameter, R = R r + i R i . The Robin condition combines the shear stress and the horizontal velocity at the ocean surface. We show that this condition describes wave damping related to surface phenomena like elastic films or thin viscous fluid layers. It may also model wave generati...
Wave-induced Lagrangian drift in a porous seabedNARA Subscribed
The mean drift in a porous seabed caused by long surface waves in the overlying fluid is investigated theoretically. We use a Lagrangian formulation for the fluid and the porous bed. For the wave field we assume inviscid flow, and in the seabed, we apply Darcy’s law. Throughout the analysis, we assume that the long-wave approximation is valid. Since the pressure gradient is nonlinear in the Lagrangian formulation, the balance...
The mammalian insulin antagonist S961 does not exhibit insulin receptor antagonism in rainbow trout in vivoNARA Subscribed
Due to their reported ‘glucose‐intolerant’ phenotype, rainbow trout have been the focus of comparative studies probing underlying endocrine mechanisms at the organismal, tissue and molecular level. A particular focus has been placed on the investigation of the comparative role of insulin, an important glucoregulatory hormone, and its interaction with macronutrients. A limiting factor in the comparative investigation of insulin...
Purpose The mobility of left atrial appendage (LAA) thrombi and changes hereof under anticoagulation may serve as a marker of both risk of embolism and efficacy of treatment. In this study, we sought to evaluate thrombus mobility and hypothesized that LAA dynamics and thrombus mobility could serve as a baseline marker of thrombus dissolvability. Methods Patients with two-dimensional transesophageal echocardiographic images of...
The diversity of Sclerotinia sclerotiorum (Lib.) de Bary isolates from western PolandNARA Subscribed
Sclerotinia sclerotiorum (Lib.) de Bary is one of the most dangerous pathogens of rapeseed ( Brassica napus L.). Rape plants are infested most often in spring during the flowering phase. The aggressive nature of this fungus as well as its pathogenicity is attributed to its mycotoxin, particularly oxalic acid. Oxalic acid is responsible for the development of acid environment in the plant which triggers off activity of hydrolyt...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
