Postcardiotomy Venoarterial Extracorporeal Membrane Oxygenation in Patients Aged 70 Years or Older

Background: There is uncertainty whether venoarterial extracorporeal membrane oxygenation (VA-ECMO) should be used in older patients with cardiopulmonary failure after cardiac surgery. Methods: This was a retrospective multicenter study of 781 patients who required postcardiotomy VA-ECMO for cardiopulmonary failure after adult cardiac surgery from 2010 to 2018 at 19 cardiac surgery centers. A para

Humidity-dependent colour change in the green forester moth, Adscita statices

The colours of insects serve important visual functions in aiding mate recognition, camouflage and warning. The display of insects is usually static, as cuticle coloration does not (or hardly) change during the lifespan of a mature imago form. Here, we describe a case of humidity-dependent, brilliant coloration in the green forester moth, Adscita statices. We show, by employing spectroscopic and u

Chronic Inflammation and Atherosclerosis

Inflammation is a vital response and necessary for maintaining homeostasis. Inflammation protects against tissue damage and pathogens-but is also one of the main driving forces of the atherosclerotic plaque progression. How and why the inflammatory response is initiated in the atherosclerotic disease is not fully known, but evidence suggests modified lipids as potential antigens activating the imm

The Molecular Chaperone DNAJB6, but Not DNAJB1, Suppresses the Seeded Aggregation of Alpha-Synuclein in Cells

Alpha-synuclein (α-Syn) can misfold and aggregate, causing the degeneration of dopaminergic neurons, as seen in Parkinson's disease (PD). We recently demonstrated that DNAJB6, a co-chaperone found in Lewy bodies (LB), suppresses the aggregation of α-Syn in cells and in vitro. In this study, we compared the capacities of DNAJB1 and DNAJB6 to suppress the seeded α-Syn aggregation in HEK293 cells exp

Discovery of selective nonpeptidergic neuropeptide FF2 receptor agonists

We report the discovery and initial characterization of a novel class of selective NPFF2 agonists. HTS screening using R-SAT, a whole cell based functional assay, identified a class of aryliminoguanidines as NPFF1 and NPFF2 ligands. Subsequent optimization led to molecules exhibiting selective NPFF2 agonistic activity. Systemic administration showed that selective NPFF2 agonists (1 and 3) are acti

Analysis of carbon steels affected by bacteria using electrochemical impedance and direct current techniques

The failure of metal structures in contact with natural, untreated waters is frequently ascribed to bacterial corrosion. This study compares the corrosive effects of Vibrio natriegens (V. natriegens) when in batch and continuous flow culture. Evidence is presented for enhanced corrosion of carbon steel resulting from aerobic culture of V. natriegens with two sulfate-reducing bacteria (SRB). The co

Disease Modification by Combinatorial Single Vector Gene Therapy : A Preclinical Translational Study in Epilepsy

Gene therapy has been suggested as a plausible novel approach to achieve seizure control in patients with focal epilepsy that do not adequately respond to pharmacological treatment. We investigated the seizure-suppressant potential of combinatorial neuropeptide Y and Y2 receptor single vector gene therapy based on adeno-associated virus serotype 1 (AAV1) in rats. First, a dose-response study in th

Autocatalytic amplification of Alzheimer-associated Aβ42 peptide aggregation in human cerebrospinal fluid

Alzheimer’s disease is linked to amyloid β (Aβ) peptide aggregation in the brain, and a detailed understanding of the molecular mechanism of Aβ aggregation may lead to improved diagnostics and therapeutics. While previous studies have been performed in pure buffer, we approach the mechanism in vivo using cerebrospinal fluid (CSF). We investigated the aggregation mechanism of Aβ42 in human CSF thro

Celebrities, air travel, and social norms

The year 2018 saw the rise of a new global youth movement, Fridays for Future. The organization underlines the importance of personal accountability for greenhouse gas emissions, specifically in the context of air travel. This position is in stark contrast to views associating aeromobility with status. Celebrities in particular maintain personal brands based on frequent flying. This paper assesses

Does size matter? Attendance numbers at SI-sessions and how it affects learning conditions

Supplemental Instruction (SI) is today a well-known academic support model to address retention and student performance in higher education. However, in studies reporting the effect of SI, the number of attendees at SI-sessions are seldom mentioned or reflected upon.This study investigates if there is a lower, optimal, and upper number of SI-attendees for SI-sessions with viable learning condition

Contributions to Preventive Measures in Cyber Security

Organizations and individuals maintain and use an ever increasing amount of computer systems, either deployed locally, or in the cloud.These systems often store and handle vast amounts of data, some of which is sensitive and should be kept private.Regardless of where the data is located, there is a need to prevent data from falling into the wrong hands.To this end, this dissertation presents contr
