Bannlys alla politiska beslut som ger mer klimatutsläpp
- 2014
-
Ingår i: Dagens Nyheter.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Torftig valdebatt. Dagspolitiken klarar inte att hantera ödesfrågan om klimatet, vilket oroar oss. Vi föreslår därför ett ”utsläppsmoratorium”: inga beslut får tas som ökar utsläppen av växthusgaser. Principen måste kopplas till mål om exempelvis förnybar energi och grön infrastruktur, skriver 23 forskare och debattörer.

Förändring i ett skandinaviskt perspektiv

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Inom ämnet organisationsteori är studier av planerade förändringar vanliga, dels därför att dagens organisationer är mycket förändringsbenägna, dels för att vi som studerar organisationer tycker att det är viktigt att förstå varför och hur förändringar sker. Syftet med plaerade förändringsprocesser kan vara att utöka eller dra ner på verksamheten, att effektivisera och öka produktivitet och kvalitet. Detta görs ofta genom införande av exempelvis ny teknik och nya management verktyg/modeller. Planerade förändringaprocesser blir avgörande för vår tolkning och förståelse av dem. I det här kapitlet kommer vi att presentera översättning som ett sätt att studera förändring.

The intranasal adjuvant Endocine((TM)) enhances both systemic and mucosal immune responses in aged mice immunized with influenza antigen
- 2017

Tidskriftsartikel (refereegranskat)abstract
- Despite availability of annual influenza vaccines, influenza causes significant morbidity and mortality in the elderly. This is at least in part a result of immunosenescence; the age-dependent decrease in immunological competence that results in greater susceptibility to infections and reduced responses to vaccination. To improve protective immune responses in this age group, new vaccines strategies, such as the use of adjuvants, are needed. Here, we evaluated the mucosal vaccine adjuvant Endocine(TM), formulated with split influenza antigen and administered intranasally in aged (20-month old) mice. Humoral immune responses were assessed and compared to unadjuvanted intranasal and subcutaneous vaccines. We show that formulation with Endocine(TM) significantly enhances hemagglutination inhibition (HI) titers, as well as serum IgG and mucosal IgA antibody titers, compared to both types of unadjuvanted vaccines. Thus, our results indicate that intranasal vaccination with Endocine(TM) is a possible approach for the development of mucosal influenza vaccines for the elderly.

The mucosal adjuvant 1 Endocine™ increases immune responses to influenza antigen in aged mice
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- More effective influenza vaccines for the elderly population is needed. The vaccines used today are less effective in elderly compared to in adults. It is more difficult to stimulate a protective immune response in elderly due to immunosenescence. Elderly people have a decline in both humoral and cell mediated immunity, which make them more susceptible to viral infections. The aim of this study was to evaluate the mucosal adjuvant Endocine™ together with split influenza antigen in different ages of BALB/c mice (15, 20 and 25 months old). The results from this study show that a nasal influenza vaccine formulated with Endocine™ enhanced both systemic and mucosal immune responses compared to an unadjuvanted vaccine delivered subcutaneously or intra nasal in aged mice. However, in the 25 months old mice only a very modest immune response was detected. Although the influenza-specific immune responses in aged mice were not induced to the same levels as achieved in young mice, the results show that nasal vaccine formulated with Endocine™ could provide benefits for the elderly.

Uncontrolled asthma predicts severe COVID-19: a report from the Swedish National Airway Register.

Tidskriftsartikel (refereegranskat)abstract
- Severe asthma increases the risk of severe COVID-19 outcomes such as hospitalization and death. However, more studies are needed to understand the association between asthma and severe COVID-19.A cohort of 150,430 adult asthma patients were identified in the Swedish National Airway Register (SNAR) from 2013 to December 2020. Data on body mass index, smoking habits, lung function, and asthma control test (ACT) were obtained from SNAR, and uncontrolled asthma was defined as ACT ⩽19. Patients with severe COVID-19 were identified following hospitalization or in death certificates based on ICD-10 codes U07.1 and U07.2. The Swedish Prescribed Drug register was used to identify comorbidities and data from Statistics Sweden for educational level. Multivariate logistic regression analyses were used to estimate associations with severe COVID-19.Severe COVID-19 was identified in 1067 patients (0.7%). Older age (OR=1.04, 95% CI=1.03-1.04), male sex (1.42, 1.25-1.61), overweight (1.56, 1.27-1.91), obesity (2.12, 1.73-2.60), high-dose inhaled corticosteroids in combination with long-acting β-agonists (1.40, 1.22-1.60), dispensed oral corticosteroids ⩾2 (1.48, 1.25-1.75), uncontrolled asthma (1.64, 1.35-2.00), cardiovascular disease (1.20, 1.03-1.40), depression (1.47, 1.28-1.68), and diabetes (1.52, 1.29-1.78) were associated with severe COVID-19, while current smoking was inversely associated (0.63, 0.47-0.85). When comparing patients who died from COVID-19 with those discharged alive from hospital until 31 December 2020, older age, male sex, and current smoking were associated with COVID-19 death.Patients with uncontrolled asthma and high disease burden, including increased asthma medication intensity, should be identified as risk patients for severe COVID-19. Furthermore, current smoking is strongly associated with COVID-19 death in asthma.

Comparison of different sampling schemes for wireless control subject to packet losses
- 2015

Ingår i: First International Conference on Event-Based Control, Communication, and Signal Processing. - 9781467378888

Konferensbidrag (refereegranskat)abstract
- Three different approaches to reduce the amount of communication in wireless control subject to packet losses have been evaluated in an extensive simulation study. The sampling approaches are: slow periodic, event-based and self-triggered sampling. They are ranked based on their integrated absolute error (IAE) control performance and also compared with fast periodic sampling. The three approaches have surprisingly equal control performance in the nominal case (without packet losses) for a wide range of test scenarios (process models, controller tunings etc.). With packet losses the importance of re-transmissions becomes evident.

- Molecular motor-based nanodevices require organized cytoskeletal filament guiding along motility-promoting tracks, confined by motility-inhibiting walls. One way to enhance motility quality on the tracks, particularly in terms of filament velocity but also the fraction of motile filaments, is to optimize the surface hydrophobicity. We have investigated the potential to achieve this for the actin myosin II motor system on trimethylchlorosilane (TMCS)-derivatized SiO2 surfaces to be used as channel floors in nanodevices. We have also investigated the ability to supress motility on two new polymer resists, TU7 (for nanoimprint lithography) and CSAR 62 (for electron beam and deep UV lithography), to be used as channel walls. We developed a chemical-vapor deposition tool for silanizing SiO2 surfaces in a controlled environment to achieve different surface hydrophobicities (measured by water contact angle). In contrast to previous work, we were able to fabricate a wide range of contact angles by varying the silanization time and chamber pressure using only one type of silane. This resulted in a significant improvement of the silanization procedure, producing a predictable contact angle on the surface and thereby predictable quality of the heavy meromyosin (HMM)-driven actin motility with regard to velocity. We observed a high degree of correlation between the filament sliding velocity and contact angle in the range 10-86 degrees, expanding the previously studied range. We found that the sliding velocity on TU7 surfaces was superior to that on CSAR 62 surfaces despite similar contact angles. In addition, we were able to suppress the motility on both TU7 and CSAR 62 by plasma oxygen treatment before silanization. These results are discussed in relation to previously proposed surface adsorption mechanisms of HMM and their relationship to the water contact angle. Additionally, the results are considered for the development of actin-myosin based nanodevices with superior performance with respect to actin-myosin functionality.
