Tidskriftsartikel (refereegranskat)abstract
- In a cross-over design, 82 women and men recorded their food intake by a precoded 7-day record book (PR) including both standard portions in household measures and photographs, and a weighed 7-day record (WR), respectively. Single 24-h urine samples, for determination of nitrogen excretion, were collected for 39 subjects during the WR period. Comparing the PR to the WR method, the mean intake of some foods, as cheese, was higher, and bread and vegetables lower. For energy and nutrients, the fat energy percent (E%) was higher, and protein E%, dietary fibre, iron, thiamin, folate, carotene and α-tocopherol were all lower. Protein intake registered by the PR method was 20% lower compared to 24-h urine samples, and 11% lower for the WR method. The results indicate that some of the standard portion sizes, used by the PR method, contributed to the observed differences in food and nutrient intakes. The subjects found it easier and less time-consuming to record their food intake with the PR than with the WR method. The time spent on processing data was reduced by 50% when using the PR method. The results of the study will be used for improvements in the design of the PR for use in large-scale dietary surveys for monitoring dietary habits.

Tidskriftsartikel (refereegranskat)abstract
- The herpes simplex virus type 1 (HSV-1) origin binding protein, OBP, is a DNA helicase specifically stimulated by the viral single strand DNA-binding protein, ICP-8. The stimulation is dependent on direct protein-protein interactions between the C-terminal domain of OBP, delta OBP, and ICP 8 (Boehmer, P.E., Craigie, M.C., Stow, N.D., and Lehman, I.R. (1994) J. Biol. Chem. 269, 29329-29334). We have now observed that this interaction is dramatically influenced by the nature of the DNA ligand. Stable complexes between delta OBP, ICP 8, and double-stranded DNA, presented either as a specific duplex oligonucleotide or a restriction fragment containing the HSV-1 origin of replication, oriS, can be detected by gel chromatography and gel electrophoresis. In contrast, a single-stranded oligonucleotide, oligo(dT)65, will completely disrupt the complex between delta OBP and ICP 8. We therefore suggest that the interaction between delta OBP and ICP 8 serves to position the single strand DNA-binding protein with high precision onto single-stranded DNA at a replication fork or at an origin of DNA replication.

Molecular Weight Distribution, Measured by HPSEC, and Viscosity of Water-Soluble Dietary Fiber in Carrots following Different Types of Processing
- 1995

Ingår i: Journal of Agricultural and Food Chemistry. - : American Chemical Society (ACS). - 0021-8561 .- 1520-5118. ; 43:10, s. 2692-2697

Tidskriftsartikel (refereegranskat)abstract
- The molecular weight distribution, measured by HPSEC, and the viscosity of the water-soluble dietary fiber isolated from variously processed/cooked carrots were investigated. The carrots were studied raw, frozen, blanched, soured, microwaved, and boiled. The fibers were isolated after enzymatic digestion of protein and starch to simulate the situation in the gastrointestinal tract. The degree of polymerization (DP) and the viscosity were highly dependent on the type of processing/cooking and in general followed the degree of heat treatment. Thus, the DP values were similar with raw and frozen carrots, whereas blanched carrots had a lower DP. Further, only minor differences in DP could be observed among blanched, soured, and microwaved material, and the most pronounced degradation was obtained in boiled material. The viscosity was in accordance with the DP measurements and decreased in the order raw > blanched > boiled.

Competition between thyroid hormone receptor-associated protein (TRAP) 220 and transcriptional intermediary factor (TIF) 2 for binding to nuclear receptors. Implications for the recruitment of TRAP and p160 coactivator complexes

Tidskriftsartikel (refereegranskat)abstract
- Transcriptional activation by nuclear receptors (NRs) involves the concerted action of coactivators, chromatin components, and the basal transcription machinery. Crucial NR coactivators, which target primarily the conserved ligand-regulated activation (AF-2) domain, include p160 family members, such as TIF2, as well as p160-associated coactivators, such as CBP/p300. Because these coactivators possess intrinsic histone acetyltransferase activity, they are believed to function mainly by regulating chromatin-dependent transcriptional activation. Recent evidence suggests the existence of an additional NR coactivator complex, referred to as the thyroid hormone receptor-associated protein (TRAP) complex, which may function more directly as a bridging complex to the basal transcription machinery. TRAP220, the 220-kDa NR-binding subunit of the complex, has been identified in independent studies using both biochemical and genetic approaches. In light of the functional differences identified between p160 and TRAP coactivator complexes in NR activation, we have attempted to compare interaction and functional characteristics of TIF 2 and TRAP220. Our findings imply that competition between the NR-binding subunits of distinct coactivator complexes may act as a putative regulatory step in establishing either a sequential activation cascade or the formation of independent coactivator complexes.

Rapport (populärvet., debatt m.m.)abstract
- Studierna har koncentrerats på tre problemzoner i det angivna snittet, nämligen varuhuskvarterens ovårdade block, parkeringskvarterens ödemarker och de nya bostadskvarterens oklara blandning av buskar och bilar. Möjligheterna i dessa tre zoner har utvecklats och bearbetats individuellt och i grupp, i projekt och riktlinjer.
