AHA! festival 2015
- 2015
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The AHA festival investigates the borders between art and science in a three-day event at the Chalmers University of Technology hosted by the Department of Architecture. An international festival intended to provide enlightening experiences, staging surprises, new thoughts and displaced perspectives that lead to alternative modes of thinking about the space between art and science. We invite scientists (physicists, historians, mathematicians, medical students), artists (dancers, musicians, painters, poets, chefs) and not least architects, who reside in these borderlands and wish to share their vision and work. The key intention is to celebrate both art and science as key knowledge building devices.

- All biosynthetically active cells are able to export and import metabolites, the small molecule intermediaries of metabolism. In dense cell populations, this hallmark of cells results in the intercellular exchange of a wide spectrum of metabolites. Such metabolite exchange enables metabolic specialization of individual cells, leading to far reaching biological implications, as a consequence of the intrinsic connection between metabolism and cell physiology. In this chapter, we discuss methods on how to study metabolite exchange interactions by using self-establishing metabolically cooperating communities (SeMeCos) in the budding yeast Saccharomyces cerevisiae. SeMeCos exploit the stochastic segregation of episomes to progressively increase the number of essential metabolic interdependencies in a community that grows out from an initially prototrophic cell. By coupling genotype to metabotype, SeMeCos allow for the tracking of cells while they specialize metabolically and hence the opportunity to study their progressive change in physiology.

Microfluidic technology for investigation of protein function in single adherent cells
- 2019

Ingår i: Methods in Enzymology. - : Elsevier. - 1557-7988 .- 0076-6879.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Instrumental techniques and associated methods for single cell analysis, designed to investigate and measure a broad range of cellular parameters in search of unique features, address key limitations of conventional cell-based assays with their ensemble average response. While many different single cell techniques exist for suspension cultures, which can process and characterize large numbers of individual cells in rapid succession, the access to surface-immobilized cells in typical 2D and 3D culture environments remains challenging. Open space microfluidics has created new possibilities in this area, allowing for exclusive access to single cells in adherent cultures, even at high confluency. In this chapter, we briefly review new microtechnologies for the investigation of protein function in single adherent cells, and present an overview over related recent applications of the multifunctional pipette (Biopen), a microfluidic multi-solution dispensing system that uses hydrodynamic confinement in open volume environments in order to establish a superfusion zone over selected single cells in adherent cultures.

Effects of Long-Term Storage Time and Original Sampling Month on Biobank Plasma Protein Concentrations
- 2016

Tidskriftsartikel (refereegranskat)abstract
- The quality of clinical biobank samples is crucial to their value for life sciences research. A number of factors related to the collection and storage of samples may affect the biomolecular composition. We have studied the effect of long-time freezer storage, chronological age at sampling, season and month of the year and on the abundance levels of 108 proteins in 380 plasma samples collected from 106 Swedish women. Storage time affected 18 proteins and explained 4.8–34.9% of the observed variance. Chronological age at sample collection after adjustment for storage-time affected 70 proteins and explained 1.1–33.5% of the variance. Seasonal variation had an effect on 15 proteins and month (number of sun hours) affected 36 proteins and explained up to 4.5% of the variance after adjustment for storage-time and age. The results show that freezer storage time and collection date (month and season) exerted similar effect sizes as age on the protein abundance levels. This implies that information on the sample handling history, in particular storage time, should be regarded as equally prominent covariates as age or gender and need to be included in epidemiological studies involving protein levels.

Considering a Baby? Responsible Screening for the Future : Ethical and social implications for implementation and use of preconception expanded carrier screening in Sweden
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Preconception expanded carrier screening is a novel technology that involves the offer of a screening test for many recessive diseases (via an expanded screening panel) to prospective parents, with no priori risk. Test positive couples have a number of reproductive choices; prenatal diagnosis and aborting affected fetus, IVF and preimplantation genetic diagnosis, sperm or ovum donation or simply accept the risk. The test had been piloted in studies and can potentially be implemented in Europe. Therefore, it seemed pertinent to evaluate stakeholders’ perspectives on ethical and social implications of implementing and using preconception ECS in Sweden.Two main stakeholders were examined; healthcare professionals and health policymaking experts, via a mix of qualitative methods for data collection and data analysis. In Study I, we employed in-depth interviews to collect data and content analysis to analyze it. In Studies III and IV, expert interviews were used to gather data while thematic analysis was utilized to interpret it. Furthermore, in Study II, an ethical concept namely; reproductive autonomy, was critically discussed within a setting that expects a couple to make a conjoint reproductive decision about preconception ECS, while each partner still upholds his or her individual autonomy.The main findings of the empirical studies (Studies I, III and IV) echo to a great extent the prevailing ethical and social debates associated with the novel technology. Respondents expressed concerns with reproductive autonomy, medicalization, prioritization of health resources, discrimination and long term societal changes. Furthermore, respondents emphasized the importance to observe Swedish values, such as human dignity, equality and solidarity, when assessing a preconception ECS program. In addition, they described practicalities of implementation and political considerations that are pertinent to the Swedish context. Finally, some respondents recognized the advantages of reduced suffering and decrease in fetal anomalies and abortion as a consequence of preconception ECS.Study II, proposed a notion of couple autonomy, where certain demands if met, a couple’s reproductive decision can be accepted by healthcare staff as autonomous.The findings, in this thesis, steer towards non implementation of preconception ECS in its current status within the publicly-funded healthcare system in Sweden. This is because healthcare providers and experts were of the opinion that it would not solve a medical need, threaten Swedish values and use up resources extensively.

Definition of Tubular Anatomic Structures from Arbitrary Stereo Lithographic Surface

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- An accurate description of anatomies and dynamics of vessels is crucial to understand their characteristics and improve surgical techniques, thus it is the basis, in addition to surgeon experience, on which stent design and operation procedures rely. The process of producing this description is user intensive, and recent improvement in image processing of medical3D imaging allows for a more automated workflow. However, there is a need to bridge the gap from a processed geometry to a robust mathematical computational grid. By sequentially segmenting a tubular anatomic structure, here defined by a stereo lithographic (STL) surface, an initial centerline is formed by connecting centroids of orthogonal cross-sectional contours along the length of the structure. Relying on the initial centerline, a set of non-overlapping 2D cross sectional contours are defined along the centerline, a centerline which is updated after the 2D contours are produced. After a second iteration of producing 2D contours and updating the centerline, a full description of the structure is created. Our method for describing vessel geometry shows good coherence to existing method. The main advantages of our method include the possibility of having arbitrary triangulated STL surface input, automated centerline definition, safety against intersecting cross-sectional contours and automatic clean-up of local kinks and wrinkles.
