C-terminal α-amidation is the final and essential step in the biosynthesis of several peptide hormones. Peptidylglycine α-amidating monooxygenase (PAM) is the only known enzyme to catalyse this reaction. PAM amidating activity (AMA) is known to be present in human circulation, but its physiological role and significance as a clinical biomarker remains unclear. We developed a PAM-specific amidation
Background: Treatment-related white blood cell (WBC) toxicity has been associated with an inferior prognosis in different malignancies, including anal cancer. The aim of the present study was to investigate predictors of WBC grade ≥ 3 (G3+) toxicity during chemoradiotherapy (CRT) of anal cancer. Methods: Consecutive patients with locally advanced (T2 ≥ 4 cm—T4 or N+) anal cancer scheduled for two
Spinel iron oxide nanoparticles of different mean sizes in the range 10-25 nm have been prepared by surfactant-free up-scalable near- and super-critical hydrothermal synthesis pathways and characterized using a wide range of advanced structural characterization methods to provide a highly detailed structural description. The atomic structure is examined by combined Rietveld analysis of synchrotron
Introduction:It has been suggested that the future of diagnostic imaging relies on engagement inresearch and evidence-based practice. This implies a role transition from a clinical radiographer to aclinical radiographer-researcher. Clinical radiographers’stimuli for engaging in research in Nordiccountries are unknown. This study aimed to address this gap.Methods:Cross-sectional data collection via
Pollinators face multiple pressures and there is evidence of populations in decline. As demand for insect-pollinated crops increases, crop production is threatened by shortfalls in pollination services. Understanding the extent of current yield deficits due to pollination and identifying opportunities to protect or improve crop yield and quality through pollination management is therefore of inter
The intensive discussions of the digitalization of everyday life in the decades around 2000 often focused on how media invaded the home, reorganizing many mundane activities and sociabilities, creating new dependencies and skills of multitasking, as well as dangers of mental overload. Easily forgotten was how the new digital life was based upon a platform of domesticated media use created earlier.
Nowadays, interactions of proteins in salt solutions and at the interface with inorganic surfaces are widely investigated as their understanding has numerous applications in medical, pharmaceutical, and biotechnological industries. However, studying these interactions is a complex task that requires appropriate strategies. Combining computational models with conventional experimental represents a
The pathogenesis of paediatric appendicitis is still an enigma. In recent years, it has become more evident that our inherent immunological responses affect the trajectory of the disease course. Long-term stress has an impact on our immune system; however, it is practically and ethically challenging to prospectively track blood measurements of cortisol-levels in asymptomatic children should an acu
The medial temporal lobe (MTL) is a nidus for neurodegenerative pathologies and therefore an important region in which to study polypathology. We investigated associations between neurodegenerative pathologies and the thickness of different MTL subregions measured using high-resolution post-mortem MRI. Tau, TAR DNA-binding protein 43 (TDP-43), amyloid-β and α-synuclein pathology were rated on a sc
Molecular additives are widely utilized to minimize non-radiative recombination in metal halide perovskite emitters due to their passivation effects from chemical bonds with ionic defects. However, a general and puzzling observation that can hardly be rationalized by passivation alone is that most of the molecular additives enabling high-efficiency perovskite light-emitting diodes (PeLEDs) are che
Following stroke, attenuation of detrimental inflammatory pathways might be a promising strategy to improve long-term outcome. In particular, cascades driven by pro-inflammatory chemokines interact with neurotransmitter systems such as the GABAergic system. This crosstalk might be of relevance for mechanisms of neuronal plasticity, however, detailed studies are lacking. The purpose of this study w

Suicide among students enrolled in post-secondary education, including university or college, is a major public health concern. Previous research has examined the effectiveness of suicide prevention programs for this population. However, the effective elements of these interventions remain unknown. This study reviewed the literature on suicide prevention programs for post-secondary students, explo
Do workers benefit from proximity to other workers with similar skill sets? This question dates back at least to Alfred Marshall. We use occupation groups to proxy skill sets and show that the answer likely depends on geographical levels, as well on regional hierarchy. Using longitudinal Swedish data, we document robust evidence consistent with highly localized spillovers at the level of sub-city
Controlling infinite dimensional models remains a challenging task for many practitioners since they are not suitable for traditional control design techniques or will result in a high-order controller too complex for implementation. Therefore, the model or the controller need to be reduced to an acceptable dimension, which is time-consuming, requires some expertise and may introduce numerical err
This paper concerns trajectory tracking control of attitude dynamics configured on SU(2). Inspired by a popular geometric tracking controller on SO(3), differential geometric tools are used to derive both continuous and discontinuous attitude controllers on the SU(2) manifold, relating these to preexisting controllers operating with imaginary quaternion errors. Additionally, a robustness result is
This paper concerns the robustness of attitude controllers for dynamics configured on the SO(3) manifold and poses a set of bilinear matrix inequalities to find an optimal controller tuning with respect to (i) the ultimate bound of the error-state trajectories when perturbed by naturally arising disturbances, and (ii) the worst-case decay rate of the tracking errors. The presented optimization pro
