Background: Outcome after acute spontaneous (non-traumatic) intracerebral haemorrhage (ICH) is influenced by haematoma volume. ICH expansion occurs in about 20% of people with acute ICH. Early haemostatic therapy might improve outcome by limiting ICH expansion.

Issues related to illumination should therefore constitute the main focus, since it is the availability of photons in time and space that drives synthesis of biomass. Further, artificial illumination (e.

Natural diversity in the catalytic properties of Rubisco indicates possibilities for improvement. Oceanic phytoplankton contain some of the most efficient Rubisco enzymes, and diatoms in particular are responsible for a significant proportion of total marine primary production as well as being a major source of CO sequestration in polar cold waters.

Due to their key roles in lipid and carbohydrate metabolism, the PPARs are important drug targets. However, for several of the PPAR drugs currently in use, adverse side effects have been reported.

The aim of this study was to evaluate whether the CellaVision preclassification feature, without a subsequent re-classification, was a sufficient approach to follow up flags reported by Sysmex XE-5000.
Methods: Pairs of blood smears from 400 samples reported with suspect flags were examined using conventional microscopy and the CellaVision features.
Isolates of five pelagic North Atlantic marine diatoms (Bacillariophyceae): , , , and were cultivated in large photobioreactors at two light and two temperature regimes to test if this affected bioactivity. We screened for bioactivity in assays representing five different therapeutic areas: diabetes II (PTP1b), cancer (melanoma cells, A2058), anti-oxidants (FRAP), immunomodulation (TNFa) and anti-infection (MRSA, , , and ). All the diatom strains showed activity in two or more assays.

It is believed that the compounds responsible for these detrimental effects are oxylipins resulting from oxidized polyunsaturated fatty acids, and that they may function as grazing deterrents. Most studies reporting these effects have exposed test organisms to diatom extracts or purified toxins, but data from in vivo exposure to intact diatoms are scarce.

This study investigated whether nocebo information provided during administration of an analgesic cream could reverse topical analgesia to hyperalgesia. Furthermore, we tested whether nocebo effects were mediated by negative emotional activation.

It has been achieved with variable success in a number of freshwater species and can be attained by artificial fertilization of genetically inactivated eggs following exposure to gamma (γ), X-ray or UV irradiation (haploid androgenesis) and by restoration of diploidy by suppression of mitosis using a pressure or thermal shock. The conditions for the genetic inactivation of the maternal genome in the European sea bass (Dicentrarchus labrax L.

The effect of freeze/thaw cycles on the metabolic profiling of microalgal extracts using HR-MS was investigated. Methanolic extracts of monocultures of Arctic marine diatoms were analyzed immediately after extraction, after seven days of storage at -78 °C (one freeze/thaw cycle), and after additional seven days at -20 °C (two freeze/thaw cycles).

This study investigated the usefulness of the "Imm Gran?" flag and the analytical and diagnostic performance of the IG measurements in a side-by-side evaluation.
Methods: In total, 408 samples were analyzed on three XE-5000 instruments.
In this study, we investigate how metabolic fingerprints are related to temperature. Six common northern temperate diatoms (Attheya longicornis, Chaetoceros socialis, Chaetoceros furcellatus, Porosira glacialis, Skeletonema marinoi, and Thalassiosira gravida) were cultivated at two different temperatures, 0.5 and 8.

The objective of the study was to determine the unnatural manner and causes of death in older people, defined as individuals at least 60 years of age at the time of death. A series of medico-legally examined deaths in older people, who were examined between January 1, 1999 and December 31, 2003, and whose deaths were considered unnatural after forensic examination were studied. All deaths took place in western Norway, in two whole counties and the north part of a third county, including one large Norwegian city and one medium-sized city on the west coast of Norway.

As part of the Norwegian Medical Association's quality assurance programme for the primary health care sector we have investigated the lasting quality of the specimens drawn for determination of Thrombotest. Blood drawn into siliconated glass tubes resulted in varying Thrombotest values, depending on the time of analysis after specimen collection. Reliable Thrombotest values are needed to be able to administer the correct dosage of warfarin.
