Cephalopod versus vertebrate eyes

Vertebrates and cephalopods are the two major animal groups that view the world through sophisticated camera-type eyes. There are of course exceptions: nautiloid cephalopods have more simply built pinhole eyes. Excellent camera type eyes are also found in other animals, such as some spider groups, a few snails, and certain marine worms, but the vast majority of large camera-type eyes belong to cep

Nanotools for biosensing and manipulating cells

In medical research and within the field of Biology, it is important to find effective tools for probing and manipulating cells, as well as tools for detecting biomolecules. These tools should be sensitive, with high specitivity, and, if aimed at interacting with cells, they should be minimally invasive. In this thesis, I investigated the potential of various nanotools for these purposes. Specific

Maternal Serum Concentrations of Per- and Polyfluoroalkyl Substances in Early Pregnancy and Small for Gestational Age in Southern Sweden

Small for gestational age (SGA) is considered an adverse birth outcome. Per- and polyfluoralkyl substances (PFAS) have become increasingly investigated as contributing environmental factors, thus far with inconclusive results. The current study aimed to investigate the hypothesized association between increased maternal PFAS levels in early pregnancy and an increased risk for SGA birth. This popul

Oxidised IL-33 drives COPD epithelial pathogenesis via ST2-independent RAGE/EGFR signalling complex

Background Epithelial damage, repair and remodelling are critical features of chronic airway diseases including chronic obstructive pulmonary disease (COPD). Interleukin (IL)-33 released from damaged airway epithelia causes inflammation via its receptor, serum stimulation-2 (ST2). Oxidation of IL-33 to a non-ST2-binding form (IL-33ox) is thought to limit its activity. We investigated whether IL-33

Development and characterization of the Portable Ice Nucleation Chamber 2 (PINCii)

The Portable Ice Nucleation Chamber 2 (PINCii) is a newly developed continuous flow diffusion chamber (CFDC) for measuring ice nucleating particles (INPs). PINCii is a vertically oriented parallel-plate CFDC that has been engineered to improve upon the limitations of previous generations of CFDCs. This work presents a detailed description of the PINCii instrument and the upgrades that make it uniq

Environmental Benefits of Rapid Fire Detection

A study has been undertaken to investigate the environmental implication of early detection of a fire for the environmental impact of the fire when taking into account the global impact of the intervention itself and the need to replace building and contents as a function of the size and duration of the fire. The various scenarios investigated show that the greatest benefit is gained if a fire is

Avskaffa den tredje uppgiften

Den så kallade tredje uppgiften är inskriven i högskole­lagen. Tanken är att högskolorna ska samverka med det omgivande samhället och verka för att kunskap och kompetens kommer samhället till nytta. Men den tredje uppgiften faller kort och bör avskaffas, menar Per Holmgren och Peter Svensson.

Numerical schemes for a moving-boundary convection-diffusion-reaction model of sequencing batch reactors

Sequencing batch reactors (SBRs) are devices widely used in wastewater treatment, chemical engineering, and other areas. They allow for the sedimentation and compression of solid particles of biomass simultaneously with biochemical reactions with nutrients dissolved in the liquid. The kinetics of these reactions may be given by one of the established activated sludge models (ASMx). An SBR is opera

Soluble CD163 predicts outcome in both chemoimmunotherapy and targeted therapy–treated mantle cell lymphoma

The outcome for patients with mantle cell lymphoma (MCL) has drastically improved with new treatments directed toward the tumor immune microenvironment, where macrophages play an important role. In MCL, the presence of M2 macrophages defined by CD163 expression in diagnostic biopsies has been associated with a worse prognosis. An alternative way to assess the abundance of M2 macrophages is by meas

The Effect of Low-Dose Glucocorticoids Over Two Years on Weight and Blood Pressure in Rheumatoid Arthritis : Individual Patient Data From Five Randomized Trials

Background: Weight gain and hypertension are well known adverse effects of treatment with high-dose glucocorticoids. Objective: To evaluate the effects of 2 years of low-dose glucocorticoid treatment in rheumatoid arthritis (RA). Design: Pooled analysis of 5 randomized controlled trials with 2-year interventions allowing concomitant treatment with disease-modifying antirheumatic drugs. Setting: 12

“They Stopped the Lives of Others”: Stateless Palestinians Facing Bureaucratic Violence in Sweden

Official calls for “failed” asylum seekers to leave Sweden ignore the difficulties and harms befalling stateless people who cannot return to previous countries of residence because they lack citizenship. Stateless people are caught in limbo, a position where they have no prospects of return or of attaining a residence permit in a predictable future.

Smooth band termination at high spin in 113I

The 113I nucleus has been studied using the 58Ni(58Ni,3p) reaction at 250 MeV with the Gammasphere/ Microball facility. Gamma-ray three-and four-fold data gated by charged particle combinations were analyzed. Multipolarities of the γ rays were assigned following the angular correlation measurements. The present study is focused on the high spin properties, where the structure is dominated by 2p-2h

Sepsis hos barn – nya nationella rekommendationer

Nationell konsensus om identifiering och akut behandling av sepsis hos barn har hittills saknats. En arbetsgrupp utsedd av Svensk barninfektionsförening har nu sammanställt ett nationellt vårdprogram som gäller barn över 28 dagars ålder (korrigerat), utan tidigare känd immunbrist, övrig immunnedsättning eller misstänkt meningit. Vårdprogrammet har grans­kats av Svensk förening för pediatrisk akutsA task force appointed by the Swedish Society of Pediatric Infectious Diseases developed national treatment recommendations for pediatric sepsis. It is limited to previously healthy children between 28 days (corrected) to 18 years of age and presented as a flow chart. Sepsis should be thought of as a life-threatening organ dysfunction caused by a dysregulated host response to infection. If the chi
