Background: Air pollution, mainly from combustion, is one of the leading global health risk factors. A susceptible group is the more than 200 million people worldwide suffering from chronic obstructive pulmonary disease (COPD). There are few data on lung deposition of airborne particles in patients with COPD and none for combustion particles. Objectives: To determine respiratory tract deposition o

Besides traditional atmospheric frying, high pressure (super-atmospheric) frying might be an alternative approach to the frying of food products. In this study, convective heat transfer coefficient during atmospheric and high pressure frying was compared. For this purpose, a pressure cooker was modified to allow the immersion of a sample into frying oil under pressure and temperature measurement o

The last two decades have seen a noticeable increase in cognitive science studies that has changed the understanding of human thinking. Historians cannot ignore this any more. Cognitive history could be explained as the study of how humans in history used their cognitive abilities in order to understand the world around them and to orient themselves in it, but also how the world outside their bodi

This work is underlain by broad-based expectations that policy interventions such as EU 2020 goals for renewable energy will continue to drive increased international trade in biomass for energy. This work focuses on where and how large volumes of biomass for bioenergy may be brought to the market in the short to medium term and sought insights in the following areas: • the manner in which demand

Aim: To investigate if the early electroencephalogram (EEG) and amplitude-integrated EEG (aEEG) in very preterm infants is affected by perinatal inflammation and brain injury, and correlates with long-term outcome. Methods: Sixteen infants born at 24-28 gestational weeks (median 25.5) had continuous EEG/aEEG during the first 72 h of life. Minimum and maximum EEG interburst intervals (IBI), and aEE

This paper presents a front-end architecture for fully integrated 60 GHz phased array receivers. It employs LO-path beamforming using a phase controlled phase-locked loop (PC-PLL). To demonstrate the architecture a circuit is implemented featuring a two stage low noise amplifier, two cascaded active mixers, and a PC-PLL. The receiver downconverts the 60 GHz signal in two steps, using LO signals fr

Background: Diabetic retinopathy and retinopathy of prematurity are diseases caused by pathological angiogenesis in the retina as a consequence of local hypoxia. The underlying mechanism for epiretinal neovascularization (tuft formation), which contributes to blindness, has yet to be identified. Neural cell adhesion molecule (N-CAM) is expressed by Muller cells and astrocytes, which are in close c

Popular Abstract in Swedish Psoriasis är en av våra vanligaste folksjukdomar, som drabbar 2-3 % av den vuxna befolkningen. Man vet i dag att många patienter med psoriasis lider av psykisk ohälsa och sänkt livskvalitet. Sjukdomen i sig innebär ofta en stor psykologisk påfrestning för patienten, men stress och psykisk ohälsa också kan vara en viktig orsak till insjuknande och återfall av psoriasis. Psychological distress is well known to be associated with psoriasis, both as a disease consequence, and as a causative factor for onset and exacerbations. Psychoneuroimmunological mechanisms have been suggested to be involved in the pathogenesis of psoriasis and have often been shown to be related to psychological distress and pruritus in psoriasis. The general aim of this thesis was to investig

Expression of the RNA-binding motif protein 3 (RBM3) has been shown to correlate with favourable clinicopathological parameters and prognosis in several cancer diseases. The aim of this study was to examine the expression and prognostic ability of RBM3 in patients with testicular non-seminomatous germ cell tumours (NSGCT).

Popular Abstract in Swedish Hur gör bakterier för att komma undan immunförsvaret? Vi har studerat hur en vanligt förekommande bakterie, grupp A streptokocker, gör för att undvika kroppens immunförsvar vid infektion. Vi har upptäckt enzymer som bidrar till bakteriens förmåga att undvika immunförsvaret genom att avväpna antikroppar. De bakteriella enzymerna kan användas i bioteknisk industri och eveA majority of the proteins of the immune system are glycosylated and the glycans of IgG are essential for its functionality. Bacteria display enzymes that modulate the glycans of the immune system to weaken the host defense and favor bacterial survival. In this thesis we aimed at exploring bacterial modulation of host glycosylation in infection and to evaluate the usefulness of bacterial enzymes i

Adolescents with psychoses usually have full recovery from their first psychotic episode, but the first relapse often arises within 2 years of the first episode. Cannabis-related psychoses are difficult to distinguish from schizophrenic psychoses. Here, we describe a particularly severe clinical case, with a first psychotic episode occurring after heavy cannabis smoking, an atypically long symptom

We report on ultrafast spectroscopy study of beta-crustacyanin, the carotenoprotein responsible for the coloration of the lobster shell. beta-Crustacyanin is formed by two closely positioned astaxanthin molecules encapsulated in protein. The 2D electronic spectroscopy together with two-color pump-probe was applied to investigate the electronic structure, the excited-state dynamics, and the influen
