- 2001

Ingår i: Annu Rev Pharmacol Toxicol. - 0362-1642. ; 41, s. 237-60

Forskningsöversikt (refereegranskat)abstract
- In spite of its proven heuristic value, the dopamine hypothesis of schizophrenia is now yielding to a multifactorial view, in which the other monoamines as well as glutamate and GABA are included, with a focus on neurotransmitter interactions in complex neurocircuits. The primary lesion(s) in schizophrenia does not necessarily involve any of these neurotransmitters directly but could deal with a more general defect, such as a faulty connectivity of developmental origin. Nevertheless, a precise identification of neurotransmitter aberrations in schizophrenia will probably provide clues for a better understanding of the disease and for the development of new treatment and prevention strategies.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- It has been proposed that the evaluation and coordination of commitments in different areas of life, such as work and family, becomes an important developmental task in late emerging adulthood (e.g., Pals, 1999). In the present study we explore how this coordination takes place by investigating how 33 (23 women) Swedish parents in late emerging adulthood reason around priorities between work and family. The participants took part in a semi-structured interview concerning their attitudes towards work/family priorities. Thematic analysis was used to analyze the material (Braun & Clarke, 2006). When describing their work/family priorities most parents talked about family as being more important than work, but many also talked about a strive for work/family balance. A small group said that work and family were equally important, but none of the participants said that they prioritized work over family. However, the results showed that wanting to prioritize family had different consequences for how different participants organized their work life. Most participants talked about how they were simply working their “regular hours”. Some, but not all, of these participants thought that working regular hours meant that their children had to spend too many hours in daycare, and some of them expressed a wish to work part time. A smaller group of participants (only women) work part time. These participants often talked about wanting to downshift and spend time with their children. In contrast, some participants talked about working long hours and putting in a lot of overtime. These participants often explained how this choice was a way for them to prioritize their family. For example, they talked about how working long hours would benefit their family financially or give them other advantages. Many participants said that their view of work/family priorities had changed when they became parents. Some of these participants said that before becoming parents they had thought that it would not be so difficult to combine work and family as it later turned out to be. Some also said that before becoming parents they had not thought much about work/family issues at all, or that their career had been more important to them before they became parents. A smaller group of participants also talked about how they expected, or had already experienced, that their view on work/family priorities would change during parenthood. For example, when their child got older and more independent they would be able to engage more in their work life. In conclusion, this study indicates that to prioritize family before work is normative among emerging adult Swedish parent, but that doing so can mean very different things to different people. Moreover, the results show that when emerging adults become parents work/family priorities is often a more pressing issue than it was before. This suggests that the transition to parenthood requires young people to negotiate their commitments in different life areas in relation to the new social realities of adult life.

Tidskriftsartikel (refereegranskat)abstract
- We have used the site-directed labeling approach to study the Ca 2+-dependent docking of factor VIIa (FVIIa) to soluble tissue factor (sTF). Nine Ca2+ binding sites are located in FVIIa and even though their contribution to the overall binding between TF and FVIIa has been thoroughly studied, their importance for local protein-protein interactions within the complex has not been determined. Specifically we have monitored the association of the ?-carboxyglutamic acid (Gla), the first EGF-like (EGF1), and the protease domains (PD) of FVIIa to sTF. Our results revealed that complex formation between sTF and FVIIa during Ca2+ titration is initiated upon Ca2+ binding to EGF1, the domain containing the site of highest Ca2+ affinity. Besides we showed that a Ca 2+-loaded Gla domain is required for an optimal association of all domains of FVIIa to sTF. Ca2+ binding to the PD seems to be of some importance for the docking of this domain to sTF. © 2003 Elsevier Science B.V. All rights reserved.

Schizophrenia: from dopamine to glutamate and back.
- 2004

Ingår i: Current medicinal chemistry. - 0929-8673. ; 11:3, s. 267-77
-
Tidskriftsartikel (refereegranskat)abstract
- The first part of the present review describes the exciting journey of dopamine stabilizers, starting in the early eighties with the development of the partial dopamine agonist (-)-3-PPP of phenylpiperidine structure, via various compounds with aminotetraline structure with preferential autoreceptor antagonist properties, and then back again to phenylpiperidine compounds carrying substituents on the aromatic ring that transformed them from partial dopamine agonists to partial dopamine receptor antagonists, such as OSU6162. OSU6162 was brought to the clinic and has in preliminary trials showed antidyskinetic and antipsychotic efficacy. The second part of this review describes results from a hypoglutamatergia mouse model for cognitive symptoms of schizophrenia, where we have tested traditional neuroleptics, new generation antipsychotics with marked 5-HT2 vs dopamine D2 receptor blockade as well as a dopamine stabilizer belonging to the partial dopamine receptor antagonist category.

The 5-HT2A receptor antagonist M100907 is more effective in counteracting NMDA antagonist- than dopamine agonist-induced hyperactivity in mice

Tidskriftsartikel (refereegranskat)abstract
- The purpose of the present study was to compare the effectiveness of the selective 5-HT2A antagonist M100907 in different psychosis models. The classical neuroleptic haloperidol was used as reference compound. Two hyperdopaminergia and two hypoglutamatergia mouse models were used. Hyperdopaminergia was produced by the DA releaser d-amphetamine or the DA uptake inhibitor GBR 12909. Hypoglutamatergia was produced by the un-competitive NMDA receptor antagonist MK-801 or the competitive NMDA receptor antagonist D-CPPene. M100907 was found to counteract the locomotor stimulant effects of the NMDA receptor antagonists MK-801 and D-CPPene, but spontaneous locomotion, d-amphetamine- and GBR-12909-induced hyperactivity were not significantly affected. Haloperidol, on the other hand, antagonized both NMDA antagonist- and DA agonist-induced hyperactivity, as well as spontaneous locomotion in the highest dose used. Based on the present and previous results we draw the conclusion that 5-HT2A receptor antagonists are particularly effective against behavioural anomalies resulting from hypoglutamatergia of various origins. The clinical implications of our results and conclusions would be that a 5-HT2A receptor antagonist, due to i a the low side effect liability, could be the preferable treatment strategy in various disorders associated with hypoglutamatergia; such conditions might include schizophrenia, childhood autism and dementia disorders.

- The use of English language as the official language in science had an undoubtable role in moving science forward but posed an extra challenge for people whose first language is not English. In this Viewpoint, six non-Native English speakers share their experience as academics, clinicians, researchers and editors who carry out the core tasks of their jobs in a second language, and suggest potential solutions to help overcome issues associated with a linguistic barrier. Their stories show the substantial challenges that non-native English speakers have to face every day regardless of their career status, but also highlight the opportunities that this form of diversity can offer.

- Eosinophils have been linked to functional dyspepsia; however, less is known about their role in irritable bowel syndrome (IBS). This study tested the hypothesis of alterations in levels of fecal eosinophil-derived neurotoxin (F-EDN) and eosinophil density and degranulation within the colonic mucosa of IBS patients compared with healthy controls (HC). Colonic biopsies were collected from 37 IBS patients and 20 HC and analyzed for eosinophil numbers and local degranulation of eosinophil cationic protein (ECP) by histologic procedures. Fecal samples were collected for F-EDN and microbiota analysis. Differentiated 15HL-60 cells were used in vitro to investigate the direct effect of live bacteria on eosinophil activation measured by a colorimetric assay with o-phenylenediamine (OPD) substrate. We observed a higher number of eosinophils and increased extracellular ECP in the mucosa of IBS patients compared with HC. Moreover, F-EDN levels in IBS samples were elevated compared with HC and positively correlated to extracellular ECP. Metagenomic analysis showed significant correlations between bacterial composition and eosinophil measurements in both HC and IBS patients. In vitro experiments revealed an increased degranulation of 15HL-60 after stimulation with Salmonella typhimurium, Salmonella enterica, and Yersinia enterocolitica. To conclude, we could demonstrate alterations related to eosinophils in IBS, and, for the first time, a positive correlation between F-EDN levels and degranulated eosinophils in the colonic mucosa of IBS patients. Together our results suggest that eosinophils play a role in the pathophysiology of IBS and the mechanisms might be linked to an altered microbiota.

I see you're in pain : the effects of partner validation on emotions in people with chronic pain
- 2015
-
Ingår i: Scandinavian Journal of Pain. - : Elsevier. - 1877-8860 .- 1877-8879. ; 6, s. 16-21

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background and aimsChronic pain not only affects the person in pain, but can also have a negative impact on relationships with loved ones. Research shows that chronic pain is associated with difficulties in marital relationships, which in turn is related to a variety of negative outcomes such as psychological distress and conflict within the family. This suggests that couples where chronic physical pain is present also struggle with emotional pain and relationship problems, and thus targeting relationship skills and interpersonal functioning might be helpful for these couples. Although studies in this area are promising, their numbers are few. In the present study, validation as a way of communicating is suggested for handling emotional expression in interpersonal interactions. Validation communicates understanding and acceptance of the other person's experience, and it has been shown to have a down-regulating effect on negative emotions. It has previously been demonstrated to be important for these couples. However, the feasibility and effects of increasing partner validation in these couples are unknown. Therefore, the aim of the present study was to investigate if a brief training session in validation for spouses would result in more validating and fewer invalidating responses towards their partners with pain, and to investigate if changes in these behavioural responses were associated with changes in emotion and pain level in the partner with pain.MethodsParticipants were 20 couples where at least one partner reported chronic pain. The study employed a within-groups design in which spouses of people with pain received validation training (without their partner's knowledge), and their validating and invalidating responses were rated pre- and post-intervention using a reliable observational scale. Also, positive and negative affect and subjective pain level in the persons with pain were rated pre- and post-intervention.ResultsResults showed that the validation training was associated with increased validating and decreased invalidating responses in the partners. Their spouses with chronic pain reported a decrease in negative affect from pre- to post-training.ConclusionsOur results indicate that the partner or closest family member, after brief validation training, increased validating responses and decreased invalidating responses towards the person with pain, which had an immediate positive impact on emotions in the other person.ImplicationsThis study suggests that using validation in interpersonal interactions is a promising tool for couples where chronic pain is present.
