Vascular Reactivity in Newly-Formed and Mature Arterialized Collateral Capillaries
Peripheral arterial occlusive disease (PAOD) is a globally-prevalent cardiovascular disease in which atherosclerotic plaques narrow arterial lumen diameters and restrict blood flow to downstream tissues. The impact of these occlusions can be mitigated by collateral vessels that connect parallel arterial branches and act as natural bypasses to maintain perfusion. In animal models that lack collateral arterioles, capillaries that connect terminal arteriolar segments can arterialize and form functional collaterals following an ischemic event; however, in the early stages of development, vasodilation is impaired. We explored the mechanism of impaired vasodilation in arterialized collateral capil...
Beyond Generalists: The Brassicaceae Pollen Specialist Osmia Brevicornis as a Prospective Model Organism when Exploring Pesticide Risk to Bees
Abstract: Bees are under threat from agricultural intensification, and species which are pollen specialists (oligolectic) are thought to have declined disproportionately compared to pollen generalists (polylectic). When assessing the risks of dietary pesticide (plant protection products) exposure to non-target beneficial insects such as wild bees, effects on pollen specialist species have seldom been considered. Research and risk assessment on pesticide risk to bees mainly use a small selection of model species, only representing pollen generalist species. Moreover, the foraging preferences of the existing model species are not always adequately matched to the crops investigated, which may l...
Mason Bees and Honey Bees Synergistically Enhance Fruit Set in Sweet Cherry Orchards
Abstract: Mason bees (Osmia spp.) are efficient fruit tree pollinators that can be encouraged to occupy and breed in artificial nesting material. In sweet cherry orchards, they are occasionally used as an alternative managed pollinator as a replacement for or in addition to honey bees (Apis mellifera). Yet, the lack of practical guidelines on management practices, for example optimal stocking rates, for both mason bee nesting material and honey bees might compromise pollination service provision. In this study, we assessed the relationship between stocking rates (honey bee hives and mason bee nesting material) and the abundance of honey bees and mason bees in 17 sweet cherry (Prunus avium) o...

COLOMBIA Piet Hoffmann arbejder som livvagt for El Mestizo, en livsfarlig, skruppelløs narkoforbryder. Hoffmann er det eneste menneske, El Mestizo stoler på. Hvad han ikke ved er, at Hoffmann arbejder undercover for den amerikanske regering. USA Kampen mod narkokartellerne i Colombia ledes fra inderkredsen i Det Hvide Hus. Lederen af kampen er nummer tre på rangstigen, lige efter præsidenten og vicepræsidenten. Han rejser til Colombia for at vise sin styrke og motivere sine soldater. Det skulle han aldrig have gjort. SVERIGE Kommissær Ewert Grens får en hemmelig opgave af sin chef. Noget er gået helt galt i Colombia. En svensk statsborger, der arbejder undercover, er indblandet. Grens og Hoffmann har mødt hinanden før – men denne gang er de på samme side.
