Research review (peer-reviewed)abstract
- The enzyme catalysing the reduction of protochlorophyllide (Pchlide) to chlorophyllide (Chlide), NADPH:Pchlide oxidoreductase (POR; EC 1.6.99.1), is a nuclear-encoded protein that is post-translationally imported to the plastid, In barley and Arabidopsis thaliana, the reduction of Pchlide is controlled by two different PORs, PORA and PORE. To characterise the possible Pchlide dependency for the import reaction, radiolabelled precursor proteins of barley PORA and PORE (pPORA and pPORB, respectively) were used for in vitro assays with isolated plastids of barley and pea with different contents of Pchlide, To obtain plastids with different endogenous levels of Pchlide, several methods were used. Barley plants were grown in darkness or in greenhouse conditions for 6 days. Alternatively, greenhouse-grown pea plants were incubated for 4 days in darkness before plastid isolation, or chloroplasts isolated from greenhouse-grown plants were incubated with delta-aminolevulinic acid (ALA), an early precursor in the Chi biosynthesis resulting in elevated Pchlide contents in the plastids, Both barley pPORA and pPORB were effectively imported into barley and pea chloroplasts isolated from the differentially treated plants, including those isolated from greenhouse-grown plants. The absence or presence of Pchlide did not significantly affect the import capacity of barley pPORA or pPORB, Assays performed on stroma-enriched fractions from chloroplasts and etioplasts of barley indicated that no post-import degradation of the proteins occurred in the stroma, irrespective of whether the incubation was performed in darkness or in light.

Patient satisfaction with nursing care in the context of health care : A literature study
- 2002

In: Scandinavian Journal of Caring Sciences. - Oxford : Wiley. - 0283-9318 .- 1471-6712. ; 16:4, s. 337-344

Research review (peer-reviewed)abstract
- To evaluate and improve the quality of care provided, it is of vital importance to investigate the quality of care in the context of health care. Patient satisfaction is a significant indicator of the quality of care. Consequently, quality work includes investigations that map out patient satisfaction with nursing care. To improve the quality of nursing care, the nurse needs to know what factors influence patient satisfaction. The aim of this literature study was to describe the influences on patient satisfaction with regard to nursing care in the context of health care. In the description of nursing care, we have used Henderson's nursing care model. The results describe eight domains that have an influence on patient satisfaction with nursing care: the socio-demographic background of the patients, patients' expectations regarding nursing care, the physical environment, communication and information, participation and involvement, interpersonal relations between nurse and patient, nurses' medical-technical competence, and the influence of the health care organization on both patients and nurses. The bulk of the literature included in the study came from the UK, Sweden and the USA. This means that the results should be applicable to health care in the western world. An important implication for future research is to continue to elucidate the factors that influence satisfaction with nursing care, as seen from the patient's perspective.

Neuropeptides and their interaction with exercise and immune function
- 2000
-
In: Immunology and Cell Biology. - Oxford : Blackwell Publishing. - 0818-9641 .- 1440-1711. ; 78:5, s. 562-570

Research review (peer-reviewed)abstract
- It is known today that the immune system is influenced by various types of psychological and physiological stressors, including physical activity. It is well known that physical activity can influence neuropeptide levels both in the central nervous system as well as in peripheral blood. The reported changes of immune function in response to exercise have been suggested to be partly regulated by the activation of different neuropeptides and the identification of receptors for neuropeptides and steroid hormones on cells of the immune system has created a new dimension in this endocrine-immune interaction. It has also been shown that immune cells are capable of producing neuropeptides, creating a bidirectional link between the nervous and immune systems. The most common neuropeptides mentioned in this context are the endogenous opioids. The activation of endogenous opioid peptides in response to physical exercise is well known in the literature, as well as the immunomodulation mediated by opioid peptides. The role of endogenous opioids in the exercise-induced modulation of immune function is less clear. The present paper will also discuss the role of other neuroendocrine factors, such as substance P, neuropeptide Y and vasoactive intestinal peptide, and pituitary hormones, including growth hormone, prolactin and adrenocorticotrophin, in exercise and their possible effects on immune function.

Climate change : using robustness as a policy response
- 2004
-
In: Building Research & Information. - London : Taylor & Francis Group. - 0961-3218 .- 1466-4321. ; 32:1, s. 71-74
-
Research review (peer-reviewed)abstract
- This commentary paper deals two issues: There is an insecurity of the predicted climate change and its impact on the built environment and there is a big time gap between the timescale for the climate change predictions and the timescale that is used for making decisions about the built environment. It is advocated that long term decisions for the built environment must be based on reliable predictions and if they are not the decisions will often make more damage than if no decisions were made at all. It is also stated that very few of the stakeholders in the building process have taken any actions to respond to the expected climate change. There is a total discrepancy between the climate change perspective and the stakeholders’ decision making perspective and it is therefore probably more efficient to cope to the current climate situation than to adapt to an uncertain very long-term climate change. For long term climate changes, robustness in the built environment probably is a more valid strategy.
