Permeability of the blood‐brain barrier induced by 915 MHz electromagnetic radiation, continuous wave and modulated at 8, 16, 50, and 200 Hz

Biological effects of electromagnetic fields (EMF) on the blood‐brain barrier (BBB) can be studied in sensitive and specific models. In a previous investigation of the permeability of the blood‐brain barrier after exposure to the various EMF‐components of proton magnetic resonance imaging (MRI), we found that the exposure to MRI induced leakage of Evans Blue labeled proteins normally not passing t

Electromagnetic field calculations used for exposure experiments on small animals in TEM-cells

Three-dimensional electromagnetic calculations for loaded transverse electromagnetic (TEM) transmission cells are presented. Based on those calculations a prediction of the perturbation of the standard uniform field in the TEM-cell, due to the scattering by inhomogeneous structures placed inside the cell cavity, is given. The influence of the dimensions of a lossy structure and its position in the

Self-reactive T cells induce and perpetuate chronic relapsing arthritis

Background: CD4+ T cells play a central role during the early stages of rheumatoid arthritis (RA), but to which extent they are required for the perpetuation of the disease is still not fully understood. The aim of the current study was to obtain conclusive evidence that T cells drive chronic relapsing arthritis. Methods: We used the rat pristane-induced arthritis model, which accurately portrays

Proteolysis of Iron Oxide-Associated Bovine Serum Albumin

Proteins are a substantial nitrogen source in soils provided that they can be hydrolyzed into bioavailable small peptides or amino acids. However, the strong associations between proteins and soil minerals restrict such proteolytic reactions. This study focused on how an extracellular fungal protease (Rhizopus sp.) hydrolyzed iron oxide-associated bovine serum albumin (BSA) and the factors that af

Managing a Century of Debt

This paper provides a consistent series for the Irish national debt since the foundation of the state. It also provides a continuous series for bond yields over the same period. The paper examines the factors behind the fluctuations in the debt burden over almost a century. The management of the debt burden by the Irish authorities has evolved over time, seeking to minimise both the burden on the

Suicide mortality after discharge from inpatient care for bipolar disorder : A 14-year Swedish national registry study

Bipolar disorder has long been associated with increased risks for suicidality; though factors associated with dying by suicide remain obscure. Here, we retrospectively examine the associations between the different phases of bipolar illness and other common comorbidities with death by suicide in the 120 days following each discharge for Swedes first admitted as inpatients for bipolar disorder dur

Impact of nasal resistance on the distribution of apneas and hypopneas in obstructive sleep apnea

Background: This study aims to investigate how increased nasal resistance affects respiratory variables in obstructive sleep apnea (OSA). In this setting, to assess how nasal resistance, as measured by 4-phase rhinomanometry, affects the distribution of hypopneas and apneas when measured with routine Sleep Polygraphy (PG). Methods: PG recordings were analysed and 4-phase rhinomanometry was conduct

Physics of viral infectivity : Matching genome length with capsid size

In this work, we review recent advances in the field of physical virology, presenting both experimental and theoretical studies on the physical properties of viruses. We focus on the double-stranded DNA (dsDNA) bacteriophages as model systems for all of the dsDNA viruses both prokaryotic and eukaryotic. Recent studies demonstrate that the DNA packaged into many dsDNA viral capsids is highly pressu

International Comparison of nature-based solutions : Project report

The four-year NATURVATION project (2016-2020), funded through the EU Horizon 2020 Programme, seeks to map and analyse existing experiences and practices in the use of nature-based solutions (NBS) to understand what enables NBS innovations and ultimately use this knowledge to inform policy and practice. One of the tasks of the project was to analyse the processes, mechanisms and tools which support
