Our study showed that increases in seasonal productivity drive earlier autumn senescence of temperate trees. Norby argues that this finding is contradicted by observations from free-air CO2 enrichment (FACE) experiments, where elevated CO2 has been found to delay senescence in some cases. We provide a detailed answer showing that the results from FACE studies are in agreement with our conclusions.
As the use of engineered nanomaterials increases, so does the risk of them spreading to natural ecosystems. Hitherto, knowledge regarding the toxic properties of nanoparticles (NP’s) and their potential interactions with natural bio-organic molecules adsorbed to them, and thereby forming surface coronas, is limited. However, we show here that the toxic effect of NPs of tungsten carbide cobalt (WC–
Aims/hypothesis. We assessed how the role of genes genetic causation in causing maturity-onset diabetes of the young (MODY) alters the response to an oral glucose tolerance test (OGTT). Methods. We studied OGTT in 362 MODY subjects, from seven European centres; 245 had glucokinase gene mutations and 117 had Hepatocyte Nuclear Factor-1 alpha (HNF-1alpha) gene mutations. Results. BMI and age were si
Objective— Stretch-induced growth of the vascular wall plays a role in hypertension and neointima formation. Its signal pathways involve integrins, cytoskeleton, membrane receptors, and ion channels, some of which are organized in cholesterol-rich, membrane domains such as lipid rafts or caveolae. This study tested the role of rafts/caveolae in stretch-induced vascular growth by manipulation of me
This study aims to investigate a potential convergence between the Green and Liberal parties of Europe regarding cultural issues of the GAL-TAN-scale, such as the environmental issue in particular. The focus on this issue is inspired by the increased debate and focus on the issue in relation to the 2019 European Parliament elections and by the theory of issue entrepreneuring strategies of the Gree
The present study explored the nature of the auditory P300 in response to filtered words in ten normal hearing adults. P300 waveforms were elicited by a classic oddball paradigm, and recorded using a net of 128 electrodes (HydroCel Geodesic Sensor Net 128 1.0.). P300 waveforms from central, parietal, temporal right and temporal left regions were selected for data collection. P300 latencies and amp
In, pheromone extracts of calling female Chiasma clathrata, L. (Lepidoptera: Geometridae), a defoliator pest of alfalfa, (Z,Z,Z)-3,6,9–heptadecatriene and (Z,Z)-6,9–cis-3,4–epoxyhepta-decadiene was identified. Chiral gas chromatography using a modified cyclodextrin and synthetic reference samples proved the natural epoxide to show (3 R.4 S)-configuration. In field trapping tests, only the pure (3/
Over the past 50 years, the concept existential question has played a less prominent role in upper secondary school curricula. The interpretation of the world view perspective has been retained until the curriculum 2000. Perspectives of personal development and interpretation of life in upper secondary school have almost disappeared. The syllabus has been content centred, reflective and analytical
The Swedish response to the Corona-crisis has been relatively moderate compared to most other countries. Sweden did not opt for a total lockdown, did not close elementary schools, day cares, bars, restaurants, movie theaters, and other places of business. Public gatherings of up to 50 people are still allowed until further notice. Sweden’s intra EU borders remain open – in contrast to its neighbor
In the present study, expression of pituitary adenylate cyclase-activating polypeptide (PACAP) in rat dorsal root ganglion (DRG) neurons and sciatic nerve following experimental sciatic nerve compression was studied with the use of quantitative immunohistochemistry and in situ hybridization. Previously, we have investigated changes in PACAP expression after nerve transection and, here, the far mor
Two species of obligate brood-parasitic Cuculus cuckoos are expanding their ranges in Beringia. Both now breed on the Asian side, close to the Bering Strait, and are found in Alaska during the breeding season. From May to July 2017, we used painted 3D-printed model eggs of two cuckoo host-races breeding in northeastern Siberia to test behavioral responses of native songbirds on both sides of the B
During a meeting held in Trento, Italy in March 2017, and organised by the COST Action CHIP ME (IS1303) to discuss about ELSI of genome-editing, many different positions emerged on the possibility to intervene on reproduction and especially on the human embryo. At the time, the Nuffield Council on Bioethics had commissioned a background paper on genome editing, and the corresponding Working Group
Regime shifts in lake ecosystems can occur in response to both abrupt and continuous climate change, and the imprints they leave in paleolimnological records allow us to investigate and better understand patterns and processes governing ecological changes on geological time scales. This synthesis investigates paleolimnological records that display apparent regime shifts and characterizes the shift
Aim: The study was undertaken to explore whether shortening of striated muscle during activity is associated with release of bound Ca2+ into the myofibrillar space as has previously been proposed in order to explain the depressant effect of active shortening. Methods: The experiments were carried out on single muscle fibres isolated from the anterior tibialis muscle of Rana temporaria. The fibres
