Effect of poly(I).poly(C12U) (Ampligen) on enteric virus (rotavirus, poliovirus and Coxsackie B3 virus) infections
1994
The effects of poly(1)-poly(C 12 U) (Ampligen) on infections with enteric viruses (rotavirus, poliovirus and Coxsackie B3 virus) were studied in vitro. Ampligen exhibited antiviral activity against rotavirus, especially when treatment was performed prior to inoculation of the virus. It was partially effective against Coxsackie B3 virus, but not against poliovirus. It is suggested that the observed effects may be due to the production of interferon induced by Ampligen
Strongavidiini - biotiinia sitova merisiilestä peräisin oleva avidiinin kaltainen proteiini
2009
Biotiinia eli vitamiinia H suurimmalla luonnossa tavatulla ei-kovalenttisella affiniteetilla sitovaa avidiinia ja sen bakteeriperäistä sukulaisproteiinia streptavidiini käytetään laajasti erilaisissa avidiini-biotiini teknologian sovellutuksissa. Alun perin avidiini löydettiin kananmunan valkuaisesta ja sen rakenne on myöhemmin selvitetty tarkasti. Avidiinilla ja streptavidiinilla on monia hyödyllisiä ominaisuuksia. Avidiinin ja streptavidiinin on havaittu biotiiniin sitouduttuaan olevan erittäin stabiileja proteiineja, jotka kestävät hyvin mm. proteolyyttisiä entsyymejä ja ne omaavat voimakkaan lämmönkestävyyden. Yksi avidiini koostuu neljästä samanlaisesta monomeeristä, joista jokainen py…
Cost analysis of the first two year of universal mass vaccination against rotavirus in Sicily
2015
Background Rotavirus vaccination (RV) is recognized by international health authority as the best strategy to prevent rotavirus gastroenteritis (RVGE) in children. Costs of RVGE were estimated in several studies and were classified into direct and indirect costs, that should be further divided into Health care and social perspective. This study aims to evaluate RVGE hospitalization costs in Sicily, before and after universal mass RV (UMRV) introduction. Methods Cases of RVGE were defined as all hospitalizations with an ICD-9-CM diagnosis code of 008.61 on any diagnosis position among children aged 0 to 59 months. Data were obtained from Hospital discharge records (HDR) of the Health Regiona…
Data from: Temporal dynamics of Puumala hantavirus infection in cyclic populations of bank voles
2017
Understanding the dynamics of zoonotic pathogens in their reservoir host populations is a prerequisite for predicting and preventing human disease epidemics. The human infection risk of Puumala hantavirus (PUUV) is highest in northern Europe, where populations of the rodent host (bank vole, Myodes glareolus) undergo cyclic fluctuations. We conducted a 7-year capture-mark-recapture study to monitor seasonal and multiannual patterns of the PUUV infection rate in bank vole populations exhibiting a 3-year density cycle. Infected bank voles were most abundant in mid-winter months during years of increasing or peak host density. Prevalence of PUUV infection in bank voles exhibited a regular, seas…
Layer-by-layer deposited multilayer assemblies of polyelectrolytes and proteins: from ultrathin films to protein arrays
2008
We have recently introduced a new method of creating ultrathin films of polyelectrolytes based on the electrostatic attraction between opposite charges. Multilayer assemblies are adsorbed in a layer-by-layer fashion from aqueous solutions of the polymers. The total film thickness can easily be adjusted by varying the ionic strength of the solution. Here, we report on the temperature stability and the water content of the multilayer assemblies. Furthermore, we have extended our concept to the incorporation of protein layers into films of synthetic polyelectrolytes. The well established system biotin/streptavidin was used to construct such multilayers, also by biospecific recognition. Adsorpt…

Konstruksjonen av EØS i norske nettaviser
2016
Masteroppgave samfunnskommunikasjon- Universitetet i Agder, 2016 Det europeiske økonomiske samarbeidsområde (EØS) er Norges tilknytning til EU. Avtalen som sikrer Norge deltakelse i EUs indre marked har vært og er fortsatt et debattert tema hvor det hersker motsetningsfylte meninger om norsk deltakelse. Avtalen i seg selv fremstår som et nasjonalt kompromiss som gjør Norge stadig mer delaktig i den europeiske integrasjonsprosessen. I et journalistisk politisk debattklima som blir stadig mer personifisert, og hvor nettavisene konkurrerer om klikk og sidevisninger, forsøker denne studien å se nærmere på hvordan EØS kommuniseres i norske nettaviser og hva som kjennetegner kommunikasjonen. Gjen…
Electroweak Gauge-Boson and Higgs Production at Small qT: Infrared Safety from the Collinear Anomaly
2012
We study the differential cross sections for electroweak gauge-boson and Higgs production at small and very small transverse-momentum $q_T$. Large logarithms are resummed using soft-collinear effective theory. The collinear anomaly generates a non-perturbative scale $q_*$, which protects the processes from receiving large long-distance hadronic contributions. A numerical comparison of our predictions with data on the transverse-momentum distribution in Z-boson production at the Tevatron and LHC is given.
The impact of wildlife and environmental factors on hantavirus infection in the host and its translation into human risk
2023
Identifying factors that drive infection dynamics in reservoir host populations is essential in understanding human risk from wildlife-originated zoonoses. We studied zoonotic Puumala orthohantavirus (PUUV) in the host, the bank vole ( Myodes glareolus ), populations in relation to the host population, rodent and predator community and environment-related factors and whether these processes are translated into human infection incidence. We used 5-year rodent trapping and bank vole PUUV serology data collected from 30 sites located in 24 municipalities in Finland. We found that PUUV seroprevalence in the host was negatively associated with the abundance of red foxes, but this process did no…
Experimental ecology on the interaction between the Puumala hantavirus and its host, the bank vole
2006
Eva Kallio tutki väitöskirjatyössään ihmisissä myyräkuumetta aiheuttavan, Hantaviruksiin kuuluvan Puumala-viruksen ja sen isäntälajin metsämyyrän välistä vuorovaikutussuhdetta. Tutkimuksessa selvisi viruksen säilyvän infektiokykyisenä pitkään isännän ulkopuolellakin ja voivan tarttua myyrästä toiseen tai myyrästä ihmiseen ilman suoraa kontaktia. Kallio osoitti myös ensimmäisen kerran hantaviruksen olevan haitallinen isäntälajilleen.Kallion osoittaman Puumala-viruksen ja metsämyyrän välisen vuorovaikutussuhteen piirteet voivat osaltaan vaikuttaa ihmisten myyräkuume-epidemioiden ilmentymiseen. Uuden tiedon avulla pystytään myös yhä luotettavammin mallintamaan ja ennustamaan epidemioiden esiin…
