- Public health policies in most European countries are concerned with how to keep older people living independently with a qualitatively good life in the community as long as possible. However, knowledge about what may characterise those seemingly 'healthy' older people is sparse. The aim of the study was to investigate the characteristics of a sample of people (75+) reporting various degrees of Quality of Life (QoL) with respect to QoL in different areas, as well as self-rated health, health problems, social support, everyday activities and sense of coherence. A postal questionnaire was sent out in spring 2001 to a randomly selected population-based sample (n= 600) in the southern parts of Sweden. A two-step cluster analysis was performed (n= 385, mean age 84.6, SD = 5.7) with 'present QoL' as clustering attribute. Three groups were disclosed, classified as high, intermediate and low present QoL, of which 33.8% could be regarded being at risk of low QoL. Those with low present QoL (18.4%) were the oldest and most vulnerable, a majority were women with 'poor or bad' self-rated health, high frequencies of health problems, low total QoL, low social support and sense of coherence and less physically active. Those with high present QoL (47.8%) reported more 'excellent or good' self-rated health, physical activity, satisfactory social support and higher sense of coherence and total QoL than the other two groups. Those with intermediate present QoL (33.8%) had more of 'poor or bad' self-rated health, more health problems were less physically active, had lower total QoL and sense of coherence, and less social support than those with high present QoL. The sample seemed to reflect the ageing process in that the respondents were at different stages of ageing. However, the fact that the level of social support, sense of coherence and self-rated health followed the same curve as QoL may indicate that some are more vulnerable to low present QoL given the same health and these should be targeted in preventive programmes since they report low QoL.

Crystal structure of YegS, a homologue to the mammalian diacylglycerol kinases, reveals a novel regulatory metal binding site

- The human lipid kinase family controls cell proliferation, differentiation, and tumorigenesis and includes diacylglycerol kinases, sphingosine kinases, and ceramide kinases. YegS is an Escherichia coli protein with significant sequence homology to the catalytic domain of the human lipid kinases. We have solved the crystal structure of YegS and shown that it is a lipid kinase with phosphatidylglycerol kinase activity. The crystal structure reveals a two-domain protein with significant structural similarity to a family of NAD kinases. The active site is located in the interdomain cleft formed by four conserved sequence motifs. Surprisingly, the structure reveals a novel metal binding site composed of residues conserved in most lipid kinases.

Tidskriftsartikel (refereegranskat)abstract
- A versatile parallel synthetic method to obtain three series of non-cyclic analogues of the first drug-like selective angiotensin II AT2 receptor agonist (1) has been developed. In analogy with the transformation of losartan to valsartan it was demonstrated that a non-cyclic moiety could be employed as an imidazole replacement to obtain AT2 selective compounds. In all the three series, AT2 receptor ligands with affinities in the lower nanomolar range were found. None of the analogues exhibited any affinity for the AT1 receptor. Four compounds, 17, 22, 39 and 51, were examined in a neurite outgrowth cell assay. All four compounds were found to exert a high agonistic effect as deduced from their capacity to induce neurite elongation in neuronal cells, as does angiotensin II.

- Structural alterations in the 2- and 5-positions of the first drug-like selective angiotensin II AT(2) receptor agonist (1) have been performed. The imidazole ring system was proven to be a strong determinant for the AT(2) selectivity, and with few exceptions all variations gave good AT(2) receptor affinities and with retained high AT(2)/AT(1) selectivities. On the contrary to the findings with AT(1) receptor agonists, the impact of structural modifications in the 5-position of the AT(2) selective compounds were less pronounced regarding activation of the AT(2) receptor. The butyloxyphenyl (56) and the propylthienyl (50) derivatives were found to exert a high agonistic effect as deduced from their capacity to induce neurite elongation in neuronal cells, as does angiotensin II.
