Simultaneous isolation of proximal and distal lung progenitor cells from individual mice using a 3D printed guide reduces proximal cell contamination of distal lung epithelial cell isolations
The respiratory epithelium consists of multiple, functionally distinct cell types and is maintained by regionally specific progenitor populations that repair the epithelium following injury. Several in vitro methods exist for studying lung epithelial repair using primary murine lung cells, but isolation methods are hampered by a lack of surface markers distinguishing epithelial progenitors along t

Site-specific CRISPR-based mitochondrial DNA manipulation is limited by gRNA import
Achieving CRISPR Cas9-based manipulation of mitochondrial DNA (mtDNA) has been a long-standing goal and would be of great relevance for disease modeling and for clinical applications. In this project, we aimed to deliver Cas9 into the mitochondria of human cells and analyzed Cas9-induced mtDNA cleavage and measured the resulting mtDNA depletion with multiplexed qPCR. In initial experiments, we fou

Experimental and theoretical near-edge x-ray-absorption fine-structure studies of NO+
Experimental near-edge x-ray-absorption fine-structure (NEXAFS) spectra of the nitrosonium NO+ ion are presented and theoretically analyzed. While neutral NO has an open shell, the cation is a closed-shell species, which for NEXAFS leads to the simplicity of a closed-shell spectrum. Compared to neutral NO, the electrons in the cation experience a stronger Coulomb potential, which introduces a shif
Individual Genetic Heterogeneity
Genetic variation has been widely covered in literature, however, not from the perspective of an individual in any species. Here, a synthesis of genetic concepts and variations relevant for individual genetic constitution is provided. All the different levels of genetic information and variation are covered, ranging from whether an organism is unmixed or hybrid, has variations in genome, chromosom

Obesity is associated with coronary artery stenosis independently of metabolic risk factors : The population-based SCAPIS study
Background and aims: Previous studies reported divergent results on whether metabolically healthy obesity is associated with increased coronary artery calcium and carotid plaques. We investigated this in a cross-sectional fashion in a large, well-defined, middle-aged population using coronary CT angiography (CCTA) and carotid ultrasound. Methods: In the SCAPIS study (50–65 years, 51% female), CCTA
A camera trap-based assessment of climate-driven phenotypic plasticity of seasonal moulting in an endangered carnivore
For many species, the ability to rapidly adapt to changes in seasonality is essential for long-term survival. In the Arctic, seasonal moulting is a key life-history event that provides year-round camouflage and thermal protection. However, increased climatic variability of seasonal events can lead to phenological mismatch. In this study, we investigated whether winter-white (white morph) and winte

On the Oxidative Valorization of Lignin to High-Value Chemicals : A Critical Review of Opportunities and Challenges
The efficient valorization of lignin is crucial if we are to replace current petroleum-based feedstock and establish more sustainable and competitive lignocellulosic biorefineries. Pulp and paper mills and second-generation biorefineries produce large quantities of low-value technical lignin as a by-product, which is often combusted on-site for energy recovery. This Review focuses on the conversio
New development : Marketization versus politicization in a perpetual strive for public audit independence
This article reports on an investigation of audit independence in the context of local public audit in Sweden. The article focuses on the influence of two different sets of interests. The results show that there is a risk that the way the results of the audit process are communicated and disseminated in an organization is influenced by political, as well as market, interests. The article reveals t
Antiretroviral therapy non-adherence among children living with HIV in Dire Dawa, Eastern Ethiopia : a case-control study
Background: In 2018, nearly 90% of the global children living with human immunodeficiency virus (HIV) were in sub-Saharan Africa (SSA). Compared to the adult population, antiretroviral therapy (ART) coverage among children was limited. However, adherence remained a problem among children though they had limited access to ART. This study was conducted to identify the risk factors of non-adher
Exploring the influence of innovativeness on the pace of internationalisation of university spin-outs : a born global perspective
To date, understanding and empirical investigation of the internationalisation processes of university spin-outs (USOs) have been limited. Few studies have explored the role of the specific characteristics of their core technology, in particular their innovativeness, as a determinant of their early internationalisation. This is also an issue which is under-explored within the general international
Comparison of two semiotic perspectives : How do students use representations in physics?
The study of students' use of representations is one of the main topics of physics education research and is guided by the overarching field of semiotics. In this paper we compare two semiotic frameworks, one coming from didactics of mathematics and one from physics education research; the theory of registers of semiotic representations and social semiotics, using the networking of theories method
Neuroinflammation in Parkinson’s Disease and its Treatment Opportunities
Parkinson’s disease (PD) is a complex, chronic, and progressive neurodegenerative disease that is characterized by irreversible dopaminergic neuronal loss in the substantia nigra. Alpha-synuclein is normally a synaptic protein that plays a key role in PD due to pathological accumulation as oligomers or fibrils. Clustered alpha-synuclein binds to the Toll-like receptors and activates the microglia,
A Novel Method for Smart Fire Detection Using Acoustic Measurements and Machine Learning : Proof of Concept
Fires are a major hazard resulting in high monetary costs, personal suffering, and irreplaceable losses. The consequences of a fire can be mitigated by early detection systems which increase the potential for successful intervention. The number of false alarms in current systems can for some applications be very high, but could be reduced by increasing the reliability of the detection system by us
Rydberg atomic antenna in strongly driven multielectron atoms
We study the role of intermediate excitations of Rydberg states as an example of Kuchiev's "atomic antenna"in above-threshold ionization of xenon, in particular their effect on the coherence between the spin-orbit-split states of the ion. We focus on the case of a laser frequency close to resonant with the spin-orbit splitting, where a symmetry (parity) argument would preclude any coherence being
