Tidskriftsartikel (refereegranskat)abstract
- This article provides nomenclature recommendations developed by an international workgroup to increase transparency and standardization of pharmacogenetic (PGx) result reporting. Presently, sequence variants identified by PGx tests are described using different nomenclature systems. In addition, PGx analysis may detect different sets of variants for each gene, which can affect interpretation of results. This practice has caused confusion and may thereby impede the adoption of clinical PGx testing. Standardization is critical to move PGx forward.

A Marine Biodiversity Observation Network for Genetic Monitoring of Hard-Bottom Communities (ARMS-MBON)
- 2020
-
Ingår i: Frontiers in Marine Science. - : Frontiers Media SA. - 2296-7745. ; 7

Tidskriftsartikel (refereegranskat)abstract
- Marine hard-bottom communities are undergoing severe change under the influence of multiple drivers, notably climate change, extraction of natural resources, pollution and eutrophication, habitat degradation, and invasive species. Monitoring marine biodiversity in such habitats is, however, challenging as it typically involves expensive, non-standardized, and often destructive sampling methods that limit its scalability. Differences in monitoring approaches furthermore hinders inter-comparison among monitoring programs. Here, we announce a Marine Biodiversity Observation Network (MBON) consisting of Autonomous Reef Monitoring Structures (ARMS) with the aim to assess the status and changes in benthic fauna with genomic-based methods, notably DNA metabarcoding, in combination with image-based identifications. This article presents the results of a 30-month pilot phase in which we established an operational and geographically expansive ARMS-MBON. The network currently consists of 20 observatories distributed across European coastal waters and the polar regions, in which 134 ARMS have been deployed to date. Sampling takes place annually, either as short-term deployments during the summer or as long-term deployments starting in spring. The pilot phase was used to establish a common set of standards for field sampling, genetic analysis, data management, and legal compliance, which are presented here. We also tested the potential of ARMS for combining genetic and image-based identification methods in comparative studies of benthic diversity, as well as for detecting non-indigenous species. Results show that ARMS are suitable for monitoring hard-bottom environments as they provide genetic data that can be continuously enriched, re-analyzed, and integrated with conventional data to document benthic community composition and detect non-indigenous species. Finally, we provide guidelines to expand the network and present a sustainability plan as part of the European Marine Biological Resource Centre (www.embrc.eu).

Tidskriftsartikel (refereegranskat)abstract
- The first experimental investigation of the electron affinity (EA) of a radioactive isotope has been conducted at the CERN-ISOLDE radioactive ion beam facility. The EA of the radioactive iodine isotope I-128 (t(1/2) = 25 min) was determined to be 3.059 052(38) eV. The experiment was conducted using the newly developed Gothenburg ANion Detector for Affinity measurements by Laser PHotodetachment (GANDALPH) apparatus, connected to a CERNI-SOLDE experimental beamline. I-128 was produced in fission induced by 1.4 GeV protons striking a thorium/tantalum foil target and then extracted as singly charged negative ions at a beam energy of 20 keV. Laser photodetachment of the fast ion beam was performed in a collinear geometry inside the GANDALPH chamber. Neutral atoms produced in the photodetachment process were detected by allowing them to impinge on a glass surface, creating secondary electrons which were then detected using a channel electron multiplier. The photon energy of the laser was tuned across the threshold of the photodetachment process and the detachment threshold data were fitted to a Wigner law function in order to extract the EA. This first successful demonstration of photodetachment at an isotope separator on line facility opens up the opportunity for future studies of the fundamental properties of negatively charged radioactive isotopes such as the EA of astatine and polonium.

β -delayed fission of isomers in Bi 188
- 2020

Ingår i: Physical Review C. - 2469-9985. ; 102:1
-
Tidskriftsartikel (refereegranskat)abstract
- β-delayed fission (βDF) decay of a low-spin (ls) and a high-spin (hs) isomer in Bi188 was studied at the ISOLDE facility at CERN. Isomer-selective laser ionization and time gating were employed to investigate each isomer separately and their βDF partial half-lives were determined: T1/2p,βDF(188Bihs)=5.6(8)×103 s and T1/2p,βDF(188Bils)=1.7(6)×103 s. This work is the first βDF study of two states in one isotope and allows the spin dependence of low-energy fission to be explored. The fission fragment mass distribution of a daughter nuclide Pb188, following the β decay of the high-spin isomer, was deduced and indicates a mixture of symmetric and asymmetric fission modes. Experimental results were compared with self-consistent mean-field calculations based on the finite-range Gogny D1M interaction. To reproduce the measured T1/2p,βDF(188Bihs), the calculated fission barrier of Pb188 had to be reduced by ≈30%. After this reduction, the measured T1/2p,βDF(188Bils) was in agreement with calculations for a few possible configurations for Bils188. Theoretical βDF probabilities for these configurations were found to be lower by a factor of 4-9 than the βDF probability of Bihs188. The fission fragment mass distribution of Pb188 was compared to the scission-point model SPY and the calculations based on the finite-range liquid-drop model. The first observation of βDF for Bi190 is also reported. © 2020 authors. Published by the American Physical Society.

- Management of acute chest pain focuses on diagnosis or safe rule-out of an acute coronary syndrome (ACS). We aim to determine the additional value of self-reported computerised history taking (CHT).Methods and analysisProspective cohort study design with self-reported, medical histories collected by a CHT programme (Clinical Expert Operating System, CLEOS) using a tablet. Women and men presenting with acute chest pain to the emergency department at Danderyd University Hospital (Stockholm, Sweden) are eligible. CHT will be compared with standard history taking for completeness of data required to calculate ACS risk scores such as History, ECG, Age, Risk factors and Troponin (HEART), Global Registry of Acute Coronary Events (GRACE), and Thrombolysis in Myocardial Infarction (TIMI). Clinical outcomes will be extracted from hospital electronic health records and national registries. The CLEOS-Chest Pain Danderyd Study project includes (1) a feasibility study of CHT, (2) a validation study of CHT as compared with standard history taking, (3) a paired diagnostic accuracy study using data from CHT and established risk scores, (4) a clinical utility study to evaluate the impact of CHT on the management of chest pain and the use of resources, and (5) data mining, aiming to generate an improved risk score for ACS. Primary outcomes will be analysed after 1000 patients, but to allow for subgroup analysis, the study intends to recruit 2000 or more patients. This ongoing project may lead to new and more effective ways for collecting thorough, accurate medical histories with important implications for clinical practice.Ethics and disseminationThis study has been reviewed and approved by the Stockholm Regional Ethical Committee (now Swedish Ethical Review Authority). Results will be published, regardless of the outcome, in peer-reviewed international scientific journals.Trial registration numberThis study is registered athttps://www.clinicaltrials.gov(unique identifier:NCT03439449).

Antibodies targeting the shared cytokine receptor IL-1 receptor accessory protein invoke distinct mechanisms to block all cytokine signaling
-
Ingår i: Cell Reports. - 2211-1247.
-
Tidskriftsartikel (refereegranskat)abstract
- Interleukin-1 (IL-1)-family cytokines are potent modulators of inflammation, coordinating a vast array of immunological responses across innate and adaptive immune systems. Dysregulated IL-1-family cytokine signaling, however, is involved in a multitude of adverse health effects, such as chronic inflammatory conditions, autoimmune diseases, and cancer. Within the IL-1 family of cytokines, six—IL-1α, IL-1β, IL-33, IL-36α, IL-36β, and IL-36γ—require the IL-1 receptor accessory protein (IL-1RAcP) as their shared co-receptor. Common features of cytokine signaling include redundancy of signaling pathways, sharing of cytokines and receptors, pleiotropy of the cytokines themselves, and multifaceted immune responses. Accordingly, targeting multiple cytokines simultaneously is an emerging therapeutic strategy and can provide advantages over targeting a single cytokine pathway. Here, we show that two monoclonal antibodies, CAN10 and 3G5, which target IL-1RAcP for broad blockade of all associated cytokines, do so through distinct mechanisms and provide therapeutic opportunities for the treatment of inflammatory diseases.

Low-molecular-weight heparin adherence and effects on survival within a randomised phase III lung cancer trial (RASTEN)
- 2019

Tidskriftsartikel (refereegranskat)abstract
- Background: Coagulation activation is a hallmark of cancer, and anticoagulants have shown tumour-inhibiting properties. However, recent trials have failed to demonstrate improved survival with low-molecular-weight heparin (LMWH) in cancer populations. This has raised the question of suboptimal adherence as a possible explanation for the lack of benefit. Still, there is no standardised method to directly monitor LMWH in patient plasma. Here, we directly determine LMWH levels in patients using the Heparin Red assay to objectively assess adherence and how this associates with the patient outcome in the RASTEN trial. Methods: RASTEN is a multicentre, randomised phase III trial investigating if the addition of LMWH to standard therapy can improve survival in small-cell lung cancer. LMWH was measured in plasma (N = 258) by the Heparin Red assay and compared with the anti-factor Xa (anti-FXa) activity assay. Results: Both methods could differentiate patients in the LMWH arm from the control arm and patients receiving therapeutic LMWH owing to thrombosis. Receiver Operating Characteristic (ROC) analysis yielded adherence rates of 85% for anti-FXa and 68% for Heparin Red. No survival benefits were found in the adherent subgroup compared with the control arm (hazard ratio [HR]: 1.26; 95% confidence interval [CI]: 0.95-1.67; P = 0.105 and HR: 1.19; 95% CI: 0.89-1.60; P = 0.248 for anti-FXa and Heparin Red, respectively). Heparin Red could define patients with high probability of adherence to LMWH treatment, which warrants prospective studies for further validation. Our finding that the LMWH-adherent subpopulation did not show improved survival excludes that the negative outcome of RASTEN was due to poor adherence. (C) 2019 The Authors.

- Common volume measurements by the Resolute Bay Incoherent Scatter Radar-North (RISR-N) and Optical Mesosphere and Thermosphere Imagers (OMTI) have been used to clarify the electrodynamic structure of a Sun-aligned arc in the polar cap. The plasma parameters of the dusk-to-dawn drifting arc and surrounding ionosphere are extracted using the volumetric imaging capabilities of RISR-N. Multipoint line-of-sight RISR-N measurements of the plasma drift are inverted to construct a time sequence of the electric field and field-aligned current system of the arc. Evidence of dramatic electrodynamic and plasma structuring of the polar cap ionosphere due to the arc is described. One notable feature of the arc is a meridionally extended plasma density depletion on its leading edge, located partially within a downward field-aligned current region. The depletion is determined to be a by-product of enhanced chemical recombination operating on a time scale of 15 min. A similarly shaped electric field structure of over 100 mV/m and line-of-sight ion temperatures nearing 3000 K were collocated with the depletion.

Association of metabolic gene polymorphisms with tobacco consumption in healthy controls
- 2004

- Polymorphisms in genes that encode for metabolic enzymes have been associated with variations in enzyme activity between individuals. Such variations could be associated with differences in individual exposure to carcinogens that are metabolized by these genes. In this study, we examine the association between polymorphisms in several metabolic genes and the consumption of tobacco in a large sample of healthy individuals. The database of the International Collaborative Study on Genetic Susceptibility to Environmental Carcinogens was used. All the individuals who were controls from the case-control studies included in the data set with information on smoking habits and on genetic polymorphisms were selected (n = 20,938). Sufficient information was available on the following genes that are involved in the metabolism of tobacco smoke constituents: CYPIAI, GSTMI, GSTTI, NAT2 and GSTPI. None of the tested genes was clearly associated with smoking behavior. Information on smoking dose, available for a subset of subjects, showed no effect of metabolic gene polymorphisms on the amount of smoking. No association between polymorphisms in the genes studied and tobacco consumption was observed; therefore, no effect of these genes on smoking behavior should be expected.

- Aim: This study aims to investigate the possible association between the risk of colorectal cancer (CRC) and allelic variants of CYP2W1 and their functional properties. Materials & methods: The distribution of three different CYP2W1 alleles (CYP2W1*1, CYP2W1*2 and CYP2W1*6) in 1785 CRC patients and 1761 healthy blood donors was determined using the TaqMan® (Applied Biosystems, CA, USA) allelic discrimination assay or allele-specific amplification. Corresponding gene products (CYP2W1.1, CYP2W1.2 and CYP2W1.6) were expressed in human colon cancer SW480 cells and their activities towards two different substrates, the duocarmycin analogs ICT2706 and ICT2726, were monitored. Results: No significant differences in the distribution of CYP2W1*1, CYP2W1*2 and CYP2W1*6 alleles were found between CRC patients and controls. The CYP2W1.1, CYP2W1.2 and CYP2W1.6 variant enzymes were expressed at the similar levels in the transfected SW480 cells and had comparable kinetics in terms of the metabolism of the duocarmycin ICT2726, as well as in the bioactivation of ICT2706 into a cytotoxic product. Conclusion: These epidemiological data obtained from a large population of CRC patients and controls cannot confirm the previously suggested decreased risk for CRC among carriers of CYP2W1*2. On the molecular level, this conclusion is further supported by the similar catalytic characteristics of the CYP2W1.1, CYP2W1.2 and CYP2W1.6 variants of CYP2W1.

- Background: In the front line in cancer care is to systematically integratepatient reported outcomes (PRO) in clinical practice. The development ofthis research program is based on The Participatory Care Model, and buildson how patients can be integrated in their care. The aim is to evaluate the effects of an interactive e-health solution for assessment of symptom burden, generating instant self-care advice and instant access to health care professionals.Methods: The hypothesis is that the intervention promotes safe and participatory care and thereby improves clinical management and health care costs. The experimental multicenter studies incorporate a mixedmethod approach. Ongoing studies include patients with pancreatic and prostate cancer using the mobile phone application in comparison to control groups in standard care. Outcomes are collected before and after treatment by questionnaires concerning capacity to understand, communicate health needs and promote healthy behaviors (health literacy), symptom burden and management and quality of life and from records and registers about disease progress and health care costs. Interviews concern participatory and meaningful care. Studies are ongoing for patients with prostate and pancreatic cancer and elderly populations living at home or in care homes.Results: By using technology patients are able to communicate symptoms and receive instant support while cared for on an outpatient basis and at the same time feel reassured that their condition is monitored by health care professionals facilitating safe and participatory care.

The toxicity of ribbon worms: alpha-nemertides or tetrodotoxin, or both?

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The marine ribbon worms (nemerteans) are predators which capture their prey by everting a proboscis carrying a mixture of toxins which brings on rapid paralysis [1]. Moreover, ribbon worms have a thick layer of epidermal mucus of similar constitution. Tetrodotoxin (TTX) has been identified as one of these toxins [2]. The extreme toxicity of TTX (lethal by ingestion of 0.5-2 mg) is due to its ability to block voltage-gated sodium channels. Although several bacterial species (among these Vibrio sp.) have been linked to its synthesis, the biogenic origin and biosynthesis is unclear. One hypothesis is that TTX production occurs in a symbiotic relationship with its host, in this case the ribbon worm [3]. We have made significant effort to identify TTX in a setup for production through the cultivation of Vibrio alginolyticus in nutrient broth infused with mucus from the ribbon worm Lineus longissimus. Toxicity was demonstrated by fraction injections into shore crabs, but no TTX was found, and it could be shown conclusively that toxicity was unrelated to TTX and the Vibrio culture itself, and rather a constituent of the ribbon worm mucus [4]. The following studies led us to the discovery of a new class of peptides, the alpha-nemertides, in the mucus of the ribbon worms, which could be directly linked to the toxic effects. A literature review of the available evidence for TTX in ribbon worms show that the evidence in most cases are indirect, although notable exceptions exist. This points to the necessity to further investigate the presence and roles of TTX and alpha-nemertides in ribbon worms.
