Memantine is a medium-affinity uncompetitive N-methyl-d-aspartate receptor antagonist and has been clinically used as a neuroprotective agent to treat Alzheimer's and Parkinson's diseases. We have examined the effect of memantine (ip 5-50 mg/kg; 4 h) on the expression of brain-derived neurotrophic factor (BDNF) and trkB receptor mRNAs in rat brain by in(More)
Since May 2009, the pandemic influenza A(H1N1) virus has been spreading throughout the world. Epidemiological data indicate that the elderly are underrepresented among the ill individuals. Approximately 1,000 serum specimens collected in Finland in 2004 and 2005 from individuals born between 1909 and 2005, were analysed by haemagglutination-inhibition test(More)
Despite vaccines and antiviral substances influenza still causes significant morbidity and mortality world wide. Better understanding of the molecular mechanisms of influenza virus replication, pathogenesis and host immune responses is required for the development of more efficient means of prevention and treatment of influenza. Influenza A virus, which(More)
OBJECTIVES To investigate the association between the geometrical properties of episiotomy and obstetric anal sphincter injuries (OASIS) because episiotomies angled at 40-60° are associated with fewer OASIS than episiotomies with more acute angles. DESIGN Case-control study. SETTING University Hospital of North Norway, Tromsø and Nordland Hospital,(More)
A hormone manipulation was performed to examine the effects of testosterone on basal and b-glucan-induced immune functions in wild-caught male and female tench Tinca tinca. Testoster-one administration elevated testosterone concentration in plasma, but did not suppress lytic activity of plasma or the chemiluminescence response of blood or head kidney(More)
BACKGROUND AND AIMS Early detection of fibrosis is important in identifying individuals at risk for advanced liver disease in non-alcoholic fatty liver disease (NAFLD). We tested whether second-harmonic generation (SHG) and coherent anti-Stokes Raman scattering (CARS) microscopy, detecting fibrillar collagen and fat in a label-free manner, might allow(More)
