A series of abrupt climate events linked to circum-North Atlantic meltwater forcing have been recognised in Holocene paleoclimate data. To address the paucity of proxy records able to characterise robustly the regional impacts of these events, we retrieved a sub-centennial resolution, well-dated core sequence from Lake Kuutsjarvi, ¨ northeast Finland. By analysing a range of paleo-environmental ...

n the Staphylococcus aureus genome, a set of highly conserved two-component systems (TCSs) composed of histidine kinases (HKs) and their cognate response regulators (RRs) sense and respond to environmental stimuli, which drive the adaptation of the bacteria. This study investigates the complex interplay between TCSs in S. aureus USA300, a predominant methicillin-resistant S. aureus strain, revealing ...

Objective: This study aimed to quantitatively investigate the accumulation of Streptococcus mutans biofilm on enamel and root surfaces and assess the amount of biofilm removal using (1) experimental toothpaste and (2) water, in a closed system of flow chamber.<p> <p<Methods: Eight sound premolars were embedded in epoxy resin and polished with silicon carbide grinding papers to display enamel ...

Enterococcus faecium (Efm) is a versatile pathogen, responsible for multidrug-resistant infections, especially in hospitalized immuno compromised patients. Its population structure has been characterized by diverse clades (A1, A2, and B (reclassified as E. lactis (Ela)), adapted to different environments, and distinguished by their resistomes and virulomes. These features only partially explain ...

Background The identification of cell type-specific genes and their modification under different conditions is central to our understanding of human health and disease. The stomach, a hollow organ in the upper gastrointestinal tract, provides an acidic environment that contributes to microbial defence and facilitates the activity of secreted digestive enzymes to process food and nutrients into ...

While Henry and Levinas are often juxtaposed, little attention has been given to their shared views on pain and pleasure. Both phenomenologists converge on the argument that an adequate account of pain and pleasure requires a critical confrontation with the theory of intentionality. This raises further questions. What roles do interiority and exteriority play in pain and pleasure? Should they be ...

Herbivores play a crucial role in shaping tundra ecosystems through their effects on vegetation, nutrient cycling, and soil abiotic factors. Understanding their habitat use, co-occurrence, and overlap is therefore essential for informing ecosystem-based management and conservation. In the High Arctic, only a marginal proportion of the land area is vegetated, and climate change is impacting ...

Fungi can be found in every marine habitat, but our knowledge about their diversity, function, and potential is still limited Studies show that marine fungi play an important role in ecosystems by contributing to nutrient cycling and forming symbiotic relationships with marine organisms. Saccharina latissima, also known as sugar kelp, is a brown algae with a circumpolar distribution in the Northern ...

Det er ca. 5-10% av Norges befolkning som har dysleksi. Denne prosentandelen gjelder også på verdensbasis. Mange av de individene det gjelder har fått påvist dysleksi i sen alder. I dagens samfunn er en avhengig av å kunne lese og skrive, og det gjelder innenfor utdanning, arbeidsmiljø og fritid. Med bakgrunn i dette er problemstillingen min: «Hvilke faktorer kan spille inn på sen oppdagelse av ...

Denne kvalitative studien utforsker norske ungdommers kommunikasjon gjennom psykiske diagnoser, med tematikken "Ungdommers bruk av diagnosespråk". Ved å innhente data gjennom semistrukturerte intervjuer med seks ungdommer fra ungdomsklubber, fikk jeg resultater som knyttes til studiens tre forskningsspørsmål: (1) Hvordan bruker ungdom psykiske diagnoser i dagligtalen? (2) Hvor har ungdom fått ...
