The genome of the model beetle and pest Tribolium castaneum.
- 2008
-
In: Nature. - 1476-4687. ; 452:7190, s. 949-55
-
Journal article (peer-reviewed)abstract
- Tribolium castaneum is a representative of earth’s most numerous eukaryotic order, a powerful model organism for the study of generalized insect development, and also an important pest of stored agricultural products. We describe its genome sequence here. This omnivorous beetle has evolved an ability to interact with a diverse chemical environment as evidenced by large expansions in odorant and gustatory receptors, as well as p450 and other detoxification enzymes. Developmental patterns in Tribolium are more representative of other arthropods than those found in Drosophila, a fact represented in gene content and function. For one, Tribolium has retained more ancestral genes involved in cell-cell communication than Drosophila, and some are expressed in the growth zone crucial for axial elongation in short germ development. Systemic RNAi in T. castaneum appears to use mechanisms distinct from those found in C. elegans, but nevertheless offers similar power for the elucidation of gene function and identification of targets for selective insect control.

To be at one's best : The evolution of Optimal Functionality and its possible implementation in an ICT-platform
- 2016
-
Doctoral thesis (other academic/artistic)abstract
- At the Nutrition and Physical Activity Research Centre for Optimal Health and Functionality through Life (NUPARC), a research gap was uncovered regarding the concept optimal functionality based on the older adult’s own perspective. The overall aim was to explore the concept of optimal functionality among older adults and the possibility of creating and developing an ICT-platform to measure it. Method: An existing cohort from NUPARC was used for recruitment in studies I-III and to some extent study IV. A scoping study design and framework was adopted for the inclusion of the articles in Study I. Study II had a descriptive design. Six focus group discussions were conducted and analysed using qualitative deductive content analysis to extend the qualitative understanding. Study III used a phenomenological approach describing the experience of mental health and its impact on the ability to function as optimally as possible. Six interviews were analysed using Giorgi’s phenomenological approach. Study IV was a feasibility study and included 8 older adults using an ICTplatform for a period of four weeks. Results: Optimal Functionality comprises three major corner stones: Body-related factors, Self-related factors and External factors (I) accompanied by nine aspects, and according to older adults it is a matter of functioning as optimally as possible (II). The three major cornerstones are intricately linked and all but the mental aspects were included in the discussions (II). Life situations affecting mental health, consequences of mental health and strategies for maintaining good mental health were described by older adults as having an impact on mental health and affecting their ability to function as optimally as possible (III). The older adults managed the usage of an ICT-tool well and it was perceived as meaningful (IV). Conclusion: Optimal functionality is holistic, subjective, dynamic and applicable to all older adults. Identification of the factors involved can help the older adults on their path to health. An ICT-platform can facilitate the identification of the factors for optimal functionality and the eventual measurement of it.

Solubilization method for isolation of photosynthetic mega- And super-complexes from conifer thylakoids
- 2021
-
In: Bio-protocol. - 2331-8325. ; 11:17
-
Journal article (peer-reviewed)abstract
- Photosynthesis is the main process by which sunlight is harvested and converted into chemical energy and has been a focal point of fundamental research in plant biology for decades. In higher plants, the process takes place in the thylakoid membranes where the two photosystems (PSI and PSII) are located. In the past few decades, the evolution of biophysical and biochemical techniques allowed detailed studies of the thylakoid organization and the interaction between protein complexes and cofactors. These studies have mainly focused on model plants, such as Arabidopsis, pea, spinach, and tobacco, which are grown in climate chambers even though significant differences between indoor and outdoor growth conditions are present. In this manuscript, we present a new mild-solubilization procedure for use with “fragile” samples such as thylakoids from conifers growing outdoors. Here, the solubilization protocol is optimized with two detergents in two species, namely Norway spruce (Picea abies) and Scots pine (Pinus sylvestris). We have optimized the isolation and characterization of PSI and PSII multimeric mega- and super-complexes in a close-to-native condition by Blue-Native gel electrophoresis. Eventually, our protocol will not only help in the characterization of photosynthetic complexes from conifers but also in understanding winter adaptation.

Evaluation of multiple transcriptomic gene risk signatures in male breast cancer
- 2021
-
In: npj Breast Cancer. - : Springer Science and Business Media LLC. - 2374-4677. ; 7:1
-
Journal article (peer-reviewed)abstract
- Male breast cancer (BCa) is a rare disease accounting for less than 1% of all breast cancers and 1% of all cancers in males. The clinical management is largely extrapolated from female BCa. Several multigene assays are increasingly used to guide clinical treatment decisions in female BCa, however, there are limited data on the utility of these tests in male BCa. Here we present the gene expression results of 381 M0, ER+ve, HER2-ve male BCa patients enrolled in the Part 1 (retrospective analysis) of the International Male Breast Cancer Program. Using a custom NanoString™ panel comprised of the genes from the commercial risk tests Prosigna®, OncotypeDX®, and MammaPrint®, risk scores and intrinsic subtyping data were generated to recapitulate the commercial tests as described by us previously. We also examined the prognostic value of other risk scores such as the Genomic Grade Index (GGI), IHC4-mRNA and our prognostic 95-gene signature. In this sample set of male BCa, we demonstrated prognostic utility on univariate analysis. Across all signatures, patients whose samples were identified as low-risk experienced better outcomes than intermediate-risk, with those classed as high risk experiencing the poorest outcomes. As seen with female BCa, the concordance between tests was poor, with C-index values ranging from 40.3% to 78.2% and Kappa values ranging from 0.17 to 0.58. To our knowledge, this is the largest study of male breast cancers assayed to generate risk scores of the current commercial and academic risk tests demonstrating comparable clinical utility to female BCa.

Design of Robotic Care : Ethical Implications of a Multi-actor Perspective
- 2022
-
In: Service Design Practices for Healthcare Innovation. - Cham : Springer. - 9783030872724 - 9783030872731 ; , s. 381-398

Book chapter (other academic/artistic)abstract
- The topic of ethically-sound robotic design is timely and societally relevant as service robots have roles with increasingly social demands in diverse service contexts. Robots fill caregiving roles for vulnerable consumers, including older adults and children. This chapter presents an empirical study investigating social and ethical ramifications of robotic elderly care from the perspective of those receiving and those providing care. Consequently, 36 actors (i.e., older adults, informal, and formal caregivers) were interviewed through generative phenomenographic interviews. This approach leveraged data-rich narratives and informant-made visualizations of future networks of care to uncover their expectations and concerns. A multi-actor perspective on the ethical implications of robotic care is captured with three thematic maps built around: (1) assistance, (2) monitoring, and (3) companionship. The results indicate that care robots could improve the wellbeing of older adults and wider care-providing networks through service, constant presence, and increased reliability. However, the visualizations of future robotic care uncovered informants’ latent fears, in addition to ethical concerns found (e.g., decline in agency, loss of privacy, and delusion). For example, formal caregivers who emphasized that they do not fear robots replacing their jobs would not place the robot close to the older person in the visualization of future care constellations. This suggests that although formal caregivers tend to give “desirable” responses in interviews, they are still reluctant to accept robots as care co-providers.

Graphene ribbons with suspended masses as transducers in ultra-small nanoelectromechanical accelerometers
- 2019
-
In: Nature Electronics. - : Nature Publishing Group. - 2520-1131. ; 2:9, s. 394-404
-
Journal article (peer-reviewed)abstract
- Nanoelectromechanical system (NEMS) sensors and actuators could be of use in the development of next-generation mobile, wearable and implantable devices. However, these NEMS devices require transducers that are ultra-small, sensitive and can be fabricated at low cost. Here, we show that suspended double-layer graphene ribbons with attached silicon proof masses can be used as combined spring–mass and piezoresistive transducers. The transducers, which are created using processes that are compatible with large-scale semiconductor manufacturing technologies, can yield NEMS accelerometers that occupy at least two orders of magnitude smaller die area than conventional state-of-the-art silicon accelerometers. With our devices, we also extract the Young’s modulus values of double-layer graphene and show that the graphene ribbons have significant built-in stresses.
