Background: One of the main causes of mortality and morbidity following subarachnoid haemorrhage (SAH) is the development of cerebral vasospasm, a frequent complication arising in the weeks after the initial bleeding. Despite extensive research, to date no effective treatment of vasospasm exists. Prostacyclin is a potent vasodilator and inhibitor of platelet aggregation. In vitro models have shown
Some theological schools consider the human conscience to be subordinate as a means to revelation of God’s nature compared to the biblical text. This can lead the reader of these texts to do violence to their own conscience by conforming it to the perceived biblical witness, although the two (the reader’s conscience and the biblical witness) can appear as in stark contrast to one another. A cognit
Scapolite-bearing orthogneisses underlying the Proterozoic Varena Iron Ore Deposit, eastern Lithuania, the western East European Craton, represent the development of a sodic alteration zone. Scapolite chemistry records fluid salinity increase with temperature, reaching its maximum at temperatures of ∼750 °C. Fluid-mineral reactions controlled the fluid KCl/NaCl ratio, enabling partial melting at p
The browning of freshwater ecosystems is increasingly evident in temperate and northern regions, with widespread ramifications for lake physics, chemistry, and biology. Contrasting results on how freshwater browning may impact fish have been reported, but there has been no comprehensive examination of how browning may cause cascading effects on individual- to population- to community-level traits
Understanding variation in survival and reproduction is key for conservation and management of bird populations. By compiling and analysing data on hatching success (i.e. proportion of nests with at least one hatched egg) from Common Eider Somateria m. mollissima, Velvet Scoter Melanitta fusca and Red-breasted Merganser Mergus serrator, all breeding on a single island in the Baltic Sea, we demonst
Experience gained from cooperation between dermatologists and vascular surgeons in 177 patients evaluated at a joint leg ulcer clinic is reported. Patients were divided into two subgroups: (i) 86 patients with healed ulcers and (ii) 91 patients with ongoing therapy-resistant ulcers. Venous insufficiency was the most common etiology in both subgroups (87% and 55%, respectively). Of previous therapy
A variety of viruses tightly pack their genetic material into protein capsids that are barely large enough to enclose the genome. In particular, in bacteriophages, forces as high as 60 pN are encountered during packaging and ejection, produced by DNA bending elasticity and self-interactions. The high forces are believed to be important for the ejection process, though the extent of their involveme
The adverse effects from reactions of reactive aggregates in concrete dams are well known worldwide. The mechanisms ruling alkali silica reactions (ASR) are partly but not fully understood. A majority of the Swedish concrete dams are so far considered to be protected from ASR due to the common use during the 50:s, 60:s and 70:s of the Swedish low alkali cement Limhamn LH. Today there is a discussi
