Ferroptosis in Parkinson's disease : glia–neuron crosstalk

Parkinson's disease (PD) is characterized by dopaminergic (DA) neuron loss and the formation of cytoplasmic protein inclusions. Although the exact pathogenesis of PD is unknown, iron dyshomeostasis has been proposed as a potential contributing factor. Emerging evidence suggests that glial cell activation plays a pivotal role in ferroptosis and subsequent neurodegeneration. We review the associatio

Flood insurance : A governance mechanism for supporting equitable risk reduction and adaptation?

Private insurance is an important governance mechanism to prepare for environmental disasters triggered by floods. It forms part of risk management and climate adaptation approaches aimed at the reduction of vulnerability and the rebuilding of damaged structures. However, flood coverage is often low. Germany is no exception to this, although it is a member state of the EU and involved in implement

Prediction of good neurological outcome in comatose survivors of cardiac arrest : a systematic review

Purpose: To assess the ability of clinical examination, blood biomarkers, electrophysiology or neuroimaging assessed within 7 days from return of spontaneous circulation (ROSC) to predict good neurological outcome, defined as no, mild, or moderate disability (CPC 1–2 or mRS 0–3) at discharge from intensive care unit or later, in comatose adult survivors from cardiac arrest (CA). Methods: PubMed, E

Can trainees safely perform pancreatoenteric anastomosis? A systematic review, meta-analysis, and risk-adjusted analysis of postoperative pancreatic fistula

Background: The complexity of pancreaticoduodenectomy and fear of morbidity, particularly postoperative pancreatic fistula, can be a barrier to surgical trainees gaining operative experience. This meta-analysis sought to compare the postoperative pancreatic fistula rate after pancreatoenteric anastomosis by trainees or established surgeons. Methods: A systematic review of the literature was perfor

The association of mitochondrial DNA copy number with incident mental disorders in women : A population-based follow-up study

BACKGROUND: Available evidence suggests that mitochondrial DNA copy number (mtDNA-CN) may differ among patients with mental disorders compared to the general population. However, whether mtDNA-CN is independently associated with the subsequent incidence of mental disorders remains unclear.MATERIAL AND METHODS: We used droplet digital PCR to measure the absolute mtDNA-CN in DNA samples obtained fro

A study of DNA interactive proteins and their origin from thermophilic Siphoviridae phages

This thesis covers the results of studies on the amino acid sequence, three-dimensional structure, and activities of two types of DNA-interactive proteins: Holliday Junction resolving enzyme (represented by Hjc_15-6 isolated from phage Tth15-6) and DNA Polymerase I (represented by PolI_G20c, isolated from phage G20c), including studies on their homologous counterparts. As these proteins originate

The Ghent system in transition: unions’ evolving role in Sweden’s multi-pillar unemployment benefit system

This article discusses the multi-faceted and changing role played by trade unions in providing unemployment benefits in Sweden, a country using the so-called Ghent system. As an important institutional feature explaining the high rate of unionisation in the Nordics, the system has been much debated. This article provides a comprehensive account of the retrenchment of the state unemployment benefit

Testosterone and coronary flow reserve: A study on Swedish men from the general population

Background: Coronary flow reserve (CFR) is an index of coronary microcirculation. No previous reports exist on the association between testosterone levels and CFR. Therefore, the aim of the present study is to explore the association between testosterone and CFR in a group of men from the general population.Material and Methods: The study consisted of 66 men with no history of cardiovascular disea

Development and applications of NMR relaxation methods to study protein and ligand dynamics.

I denna avhandling studeras proteiner. Dessa molekyler finns i många varianter, och tillsammans utför de stora delar av kroppens funktioner. Detta inkluderar olika former av signalering (till exempel närvaro av kapsaicin som ger mat hetta), molekyltransport (som till exempel syre), katalys (av till exempel matnedbrytning) och delar av kroppens struktur (som till exempel muskler). Det är därmed kanThis thesis involves the study of proteins. These molecules exist in many variants, and perform most of our bodily functions. This includes signaling (for example the presence of capsaicin, which makes food spicy), molecular transport (including oxygen), catalysis (including food digestion) and part of our body structure (such as muscles). So it is perhaps not too strange that an overwhelming frac

Administration of probiotics to healthy volunteers : effects on reactivity of intestinal mucosa and systemic leukocytes

Background: Oral administration of health-promoting bacteria is increasingly used in clinical practise. These bacteria have anti-inflammatory characteristics and modulate the immune system without major reported side effects. The mechanisms of action are not yet fully defined. Our aim was to study systemic effects of probiotics by measurements of leukocytes as well as local effects on rectal mucos

Plasma proteome changes linked to late phase response after inhaled allergen challenge in asthmatics

Background: A subset of individuals with allergic asthma develops a late phase response (LPR) to inhaled allergens, which is characterized by a prolonged airway obstruction, airway inflammation and airway hyperresponsiveness. The aim of this study was to identify changes in the plasma proteome and circulating hematopoietic progenitor cells associated with the LPR following inhaled allergen challen

Ventilation management and outcomes in out-of-hospital cardiac arrest : a protocol for a preplanned secondary analysis of the TTM2 trial

INTRODUCTION: Mechanical ventilation is a fundamental component in the management of patients post cardiac arrest. However, the ventilator settings and the gas-exchange targets used after cardiac arrest may not be optimal to minimise post-anoxic secondary brain injury. Therefore, questions remain regarding the best ventilator management in such patients. METHODS AND ANALYSIS: This is a preplanned

A combined cell and gene therapy approach for homotopic reconstruction of midbrain dopamine pathways using human pluripotent stem cells

Midbrain dopamine (mDA) neurons can be replaced in patients with Parkinson's disease (PD) in order to provide long-term improvement in motor functions. The limited capacity for long-distance axonal growth in the adult brain means that cells are transplanted ectopically, into the striatal target. As a consequence, several mDA pathways are not re-instated, which may underlie the incomplete restorati

Aortic regurgitation management : A systematic review of clinical practice guidelines and recommendations

Guidelines for the diagnosis and management of aortic regurgitation (AR) contain recommendations that do not always match. We systematically reviewed clinical practice guidelines and summarized similarities and differences in the recommendations as well as gaps in evidence on the management of AR. We searched MEDLINE and Embase (1 January 2011 to 1 September 2021), Google Scholar, and websites of

Causes, pattern, predictors, and prognostic implications of new hospitalizations after transcatheter aortic valve implantation : A long-term nationwide observational study

Aims: The aim of this study was to investigate the pattern, causes, and predictors of all new hospitalizations in patients who underwent transcatheter aortic valve implantation (TAVI). Methods and results: The nationwide Swedish TAVI registry was merged with other mandatory healthcare registries, which enabled the analysis of all TAVI procedures, new hospital admissions, and death between the year

Surveillance of COVID-19 vaccine effectiveness : A real-time case-control study in southern Sweden

The extensive register infrastructure available for coronavirus disease 2019 surveillance in Scania county, Sweden, makes it possible to classify individual cases with respect to hospitalisation and disease severity, stratify on time since last dose and demographic factors, account for prior infection and extract data for population controls automatically. In the present study, we developed a case

Picornavirus May Be Linked to Parkinson’s Disease through Viral Antigen in Dopamine-Containing Neurons of Substantia Nigra

Parkinson’s disease (PD) is a neurodegenerative disease linked with the loss of dopaminer-gic neurons in the brain region called substantia nigra and caused by unknown pathogenic mecha-nisms. Two currently recognized prominent features of PD are an inflammatory response manifested by glial reaction and T-cell infiltration, as well as the presence of various toxic mediators derived from activated g
