- In plants changes in cytosolic calcium ion concentrations ([Ca2+]cyt) have been detected after various stress treatments, including salt treatment. The involvement of a Ca2+ signal as an essential component of signalling pathways leading to downstream responses, such as gene expression, is supported only by a few studies. In this study the possible involvement of the salt stress-induced increase in [Ca2+]cyt in the signalling pathway leading to the induction of ATHB7, a homeobox gene encoding a homeodomain leucine zipper (HDZip) transcription factor was analysed. The salt-induced expression of ATHB7 was found to be independent of the Ca2+ signal evoked by salt. Instead, it was found that ATHB7 expression in shoots was not dependent on a direct contact with salt or osmoticum, whereas in roots, ATHB7 seemed to be induced by the direct contact, indicating that signals from roots cause systemic induction of ATHB7. Abscisic acid (ABA) or ABA-dependent components were found to, at least partly, to function as the systemic signal.

I solitärens skugga : Nyttobyggnadens kreativa restaurering
- 2015
-
Rapport (populärvet., debatt m.m.)abstract
- Ekonomibyggnader har alltid behövts för de huvudbyggnader som finns inom våra bevarade kulturmiljöer. Några nyttobyggnader uppskattas och används fortfarande, andra betraktas som problematiska överloppsbyggnader, många rivs. Alltför få har dokumenterats eller fått sin historia klarlagd vilket undanhållit viktig kunskap om samhällets framväxt. Vi vill synliggöra och betona vikten av att bevara och utveckla hela bebyggelsemiljöer, ofta med ett antal hus utöver huvudbyggnaden och tillhörande yttre miljö i staden eller på landet. Denna rapport visar kursdeltagarnas projektarbeten om nyttobyggnader. De har dokumenterat med traditionella och nya arbetsmetoder, inventerat och intervjuat, läst och besökt arkiv, värderat, analyserat och därefter föreslagit hur man ska ta hand om och utveckla nyttobyggnaderna i sina kulturmiljöer.

Kraft Lignin: A Valuable, Sustainable Resource, Opportunities and Challenges

Forskningsöversikt (refereegranskat)abstract
- Kraft lignin, a by-product from the production of pulp, is currently incinerated in the recovery boiler during the chemical recovery cycle, generating valuable bioenergy and recycling inorganic chemicals to the pulping process operation. Removing lignin from the black liquor or its gasification lowers the recovery boiler load enabling increased pulp production. During the past ten years, lignin separation technologies have emerged and the interest of the research community to valorize this underutilized resource has been invigorated. The aim of this Review is to give (1) a dedicated overview of the kraft process with a focus on the lignin, (2) an overview of applications that are being developed, and (3) a techno-economic and life cycle asseeements of value chains from black liquor to different products. Overall, it is anticipated that this effort will inspire further work for developing and using kraft lignin as a commodity raw material for new applications undeniably promoting pivotal global sustainability concerns.

Bilateral Prophylactic Mastectomy in Swedish Women at High Risk of Breast Cancer: A National Survey.

- BACKGROUND/OBJECTIVE:: This study attempted a national inventory of all bilateral prophylactic mastectomies performed in Sweden between 1995 and 2005 in high-risk women without a previous breast malignancy. The primary aim was to investigate the breast cancer incidence after surgery. Secondary aims were to describe the preoperative risk assessment, operation techniques, complications, histopathological findings, and regional differences. METHODS:: Geneticists, oncologists and surgeons performing prophylactic breast surgery were asked to identify all women eligible for inclusion in their region. The medical records were reviewed in each region and the data were analyzed centrally. The BOADICEA risk assessment model was used to calculate the number of expected/prevented breast cancers during the follow-up period. RESULTS:: A total of 223 women operated on in 8 hospitals were identified. During a mean follow-up of 6.6 years, no primary breast cancer was observed compared with 12 expected cases. However, 1 woman succumbed 9 years post mastectomy to widespread adenocarcinoma of uncertain origin. Median age at operation was 40 years. A total of 58% were BRCA1/2 mutation carriers. All but 3 women underwent breast reconstruction, 208 with implants and 12 with autologous tissue. Four small, unifocal, invasive cancers and 4 ductal carcinoma in situ were found in the mastectomy specimens. The incidence of nonbreast related complications was low (3%). Implant loss due to infection/necrosis occurred in 21 women (10%) but a majority received a new implant later. In total, 64% of the women underwent at least 1unanticipated secondary operation. CONCLUSIONS:: Bilateral prophylactic mastectomy is safe and efficacious in reducing future breast cancer in asymptomatic women at high risk. Unanticipated reoperations are common. Given the small number of patients centralization seems justified.

A pilot study of body awareness programs in the treatment of fibromyalgia syndrome

- Objective. To compare in a pilot study the effect of two physical therapies, the Mensendieck system (MS) and body awareness therapy (BAT) according to Roxendal, in fibromyalgia patients and to investigate differences in effect between the two interventions. Methods. Twenty female patients were randomized to either MS or BAT in a program lasting 20 weeks. Evaluations were tender point examination and questionnaires, including visual analog scales (pain intensity at worst site, muscular stiffness, evening fatigue, and global health), Fibromyalgia Impact Questionnaire (FIQ), Coping Strategies Questionnaire, Quality of Life Scales, Arthritis Self-Efficacy Scale (ASES), and disability before, immediately after, and at 6 and 18 months followup. Results. The BAT group had improved global health at 18 months followup, but lower results than the MS group. The MS group had improved FIQ, ASES other symptoms, and pain at worst site at 18 months followup. Conclusion. In the present pilot study, MS was associated with more positive changes than BAT.
