A prospective study of incident hepatitis C in 515 gastroenterology patients was conducted by follow-up sampling at 3-6 months after admission to the gastroenterology unit to test for antibodies to hepatitis C virus and for hepatitis C virus RNA. Universal precautions were implemented, and the use of multidose vials had been banned in this unit. Despite 5,964 exposure-days for several risk factors

Vernalization, the acceleration of flowering by a long period of cold temperature, ensures that many plants overwinter vegetatively and flower in spring. In Arabidopsis, allelic variation at the FRIGIDA (FRI) locus is a major determinant of natural variation in flowering time. Dominant alleles of FRI confer late flowering, which is reversed to earliness by vernalization. We cloned FRI and analyzed

The purpose was to investigate whether a new biphasic and injectable ceramic bone substitute Cerament™ that rapidly remodels to bone, may contribute to the retention of titanium implant screws during the healing period, and to analyze the pattern of bone formation around titanium implants.Titanium screws were implanted in rat tibiae and embedded with or without Cerament™ on the cortical surface. T

Popular Abstract in Swedish Utveckling och tillämpning av laserfragmentationsteknik för visualisering av väteperoxider Laserinducerad fluorescens är en etablerad optisk mätmetod för kemiskt specifik detektion och avbildning med tillämpning inom fysik, kemi och biologi. Tekniken bygger på att molekyler ska absorbera laserljus och sedan spontant sända ut ljus som kan detekteras. Det finns dock mångaThe work presented in this thesis is mainly motivated by the need for an optical diagnostic technique which can be used to visualize hydrogen peroxide (H2O2) in its gas phase. Due to the lack of bound electronic states, H2O2 cannot be detected using laser-induced fluorescence based on electronic excitation. Absorption in the ultraviolet leads to photodissociation. Thus a technique called photofrag

Overwash, the flow of water and sediment over the crest of a beach, contributes to flooding and the deposition of sand landward of the beach crest. Washover, the sand deposited by overwash, contributes to the sediment budget and migration of barrier islands. The ability to predict the occurrence, location, and thickness of overwash deposits is important for coastal residents, coastal town planners

Evaluation of incidence and survival of patients with borderline ovarian tumors in Sweden MATERIAL AND METHODS: All women diagnosed with borderline ovarian tumor in the Swedish Cancer Register 1960-2007 (n=6,252) combined with follow-up in the Swedish Death Registry to 1 July 2009 were included. Estimation of age-standardized relative survival rate according to time periods for diagnosis RESULTS:

It is investigated how the erasure efficiency for a single bit of data, stored using photon echoes, depends on the data writing time and data storage time. A comparative analysis of the erasure efficiency using a Ti:S laser system and a ring dye laser system is performed. The results clearly establish that the Ti:S laser system, which has a narrower line width than the dye laser system, could be u
