- A preschool-based dietary survey, using 7-d records, was carried out in a suburb of Stockholm. The aim was to assess the intake of food and the quality of the diet of preschool children aged 3-5 y at preschool and at home, and to compare the dietary intake with the Swedish dietary recommendations for preschool children. The respective mean intakes of protein, fat, carbohydrates and sucrose, expressed as a percentage of total energy intake were 14, 38, 50 and 9 at preschool, and at home 14, 36, 52 and 12 on weekdays, 14, 34, 55 and 16 on weekend days. The mean intakes of seven vitamins and minerals were low only for selenium as compared with the recommended level. No differences were found in nutrient density between diet at preschool and diet at home, with the exception of dietary fibre (higher at preschool). On weekdays there was a significantly higher nutrient density for calcium, zinc, selenium, vitamin A, riboflavin, vitamin C and dietary fibre compared with weekend days. Conclusion: The average intakes of energy and nutrients per meal at preschool compared with the recommended levels for children aged 4-6 y were low for all meals (breakfast, lunch and afternoon snack). This, however, was compensated for by home meals.

Context and methodological decontextualisation in nursing research with examples from phenomenography

- In both human science and nursing research the concept of context is important. However, context can be understood in different ways. The aim of this article is to elucidate, discuss and problematize context, decontextualization and recontextualization in some health care-related phenomenographical studies. A further aim is to problematize the concept of context in a wider perspective of human science, in order to gain a better understanding of phenomenographical research related to nursing care. Our analysis indicates that the complex phenomena which characterize nursing research demand a broad contextual understanding. Both the local or immediate context and the global or mediated context must be considered, as they are dialectically related. This includes the informants' experiences of the phenomenon of interest as well as the socio-cultural discourse. A balance between openness and pliability to the phenomenon is suggested. Reflection is considered an important tool in this process. Within phenomenography, the interest is directed towards conceptions of certain aspects of the world. Thus, context in a wider sense is given a subordinate role. Accordingly, phenomenography is considered to have limited applicability in nursing research when complex phenomena are to be studied.

Genetic re-targeting of adenovirus using a hyperstable scFv domain and an affibody (R) molecule against Her2/neu

- One important goal in gene therapy is to develop adenovirus (Ad) vectors that are genetically de-targeted as well as re-targeted. Genetic re-targeting of Ad using complex cell-binding ligands has previously not been possible. We have previously demonstrated that ligands for genetic re-targeting of adenoviruses must be able to fold correctly in the cytoplasm of virus producing cells, a milieu that is not conducive to the formation of disulphide bonds. Here, we describe functional Ad5 viruses with fibers and pIX capsid proteins genetically modified to contain two types of complex ligands. One is affibody® molecules, corresponding to small (6 kDa) binding proteins developed by combinatorial protein engineering using a single three-helix bundle staphylococcal protein A domain. The other type is hyperstable antibody scFv domains. The affibody molecule used here (ZH2N) is directed against Her2/neu. Recombinant viruses were constructed with ZH2N in three different positions: (i) at the C-terminus of shaft repeat 7 of de-knobbed fibers; (ii) at the C-terminus of pIX; and (iii) in the HI-loop of the fiber knob. Each of the viruses exhibited a characteristic phenotype regarding fiber content, growth and ability to infect Her2/neu expressing cells. In order to test the potentials of scFv liganded Ad vectors, a hyperstable antibody scFv against b-galactosidase was genetically incorporated into knobless fibers, in tandem with a mutated protein A domain reactive with IgG1 Fc that targeted the virus to Fc-expressing 293 cells. These fibers could be rescued into viable virions that retained the original antigen binding specificity of the scFv, demonstrating the basic potential of hyperstable scFvs for genetic re-targeting of Ad. Quite unexpectedly, the fiber content of Ad with knobless, scFv containing fibers was close to normal in contrast to other Ad with knobless fibers that generally has a much reduced fiber content. The hyperstable scFv was further fused to the C-terminus of the capsid protein pIX. The recombinant molecules could be rescued into viable viruses with wt fibers. The scFv retained its binding-specificity on the recombinant virions. The results demonstrate that, contrary to current beliefs, it is possible to construct Ad that genetically incorporates functional scFvs and other complex ligands into the virus fiber and pIX. The feasibility is demonstrated by the creation of different viruses that are re-targeted to Her2/neu. These viruses are currently in pre-clinical development.

The dopaminergic stabiliser ACR16 counteracts the behavioural primitivization induced by the NMDA receptor antagonist MK-801 in mice: implications for cognition

- The Carlsson research group has developed a series of compounds capable of stabilising the dopamine system without inducing the deleterious hypodopaminergia that encumbers the currently used antipsychotic drugs. In the present study one of these dopaminergic stabilisers, ACR16, was tested in a mouse model for cognitive deficits of schizophrenia and autism. Since we believe that hypoglutamatergia is a key element in both schizophrenia and autism we used mice rendered hypoglutamatergic by treatment with the N-methyl-D-aspartate (NMDA) antagonist MK-801. MK-801 causes both hyperactivity and a behavioural primitivization. ACR16 attenuated the MK-801-induced hyperactivity and, in addition, caused a marked improvement of behavioural quality with a movement pattern approaching that of control animals. Since we believe that the impoverishment of the behavioural repertoire caused by MK-801 may correspond to the cognitive deficits seen in schizophrenia and autism, these results suggest that ACR16 may improve cognitive status in these disorders.
