Den kognitiva vändningen. Idéhistoria och det mänskliga tänkandets historia

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

Mobilising Global Bioenergy Supply Chains: Keys to unlocking the potential of bioenergy

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

Early amplitude-integrated EEG correlates with cord TNF-alpha and brain injury in very preterm infants

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

A 60 GHz receiver front-end with PLL based phase controlled LO generation for phased-arrays

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

N-CAM Exhibits a Regulatory Function in Pathological Angiogenesis in Oxygen Induced Retinopathy

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

Psychological aspects of patients with psoriasis: Biological and clinical studies

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

Low RBM3 Protein Expression Correlates with Clinical Stage, Prognostic Classification and Increased Risk of Treatment Failure in Testicular Non-Seminomatous Germ Cell Cancer.

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).

Bacterial modulation of host glycosylation - in infection, biotechnology, and therapy

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

Atypical course in severe catatonic schizophrenia in a cannabis-dependent male adolescent: a case report.

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

Origin of the Bathochromic Shift of Astaxanthin in Lobster Protein: 2D Electronic Spectroscopy Investigation of beta-Crustacyanin

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

Expression and Prognostic Significance of Human Epidermal Growth Factor Receptors 1 and 3 in Gastric and Esophageal Adenocarcinoma.

Gastric and esophageal adenocarcinomas are major global cancer burdens. These cancer forms are characterized by a poor prognosis and a modest response to chemo- radio- and targeted treatment. Hence there is an obvious need for further enhanced diagnostic and treatment strategies. The aim of this study was to examine the expression and prognostic impact of human epidermal growth factor receptor 1 (

Prognostication after cardiac arrest.

The best predictor of good outcome after cardiac arrest is awakening from coma. The longer it takes to regain consciousness, the greater the risk of permanent brain injury. A reliable neurological assessment could previously be performed on day 3 after arrest; absence of or a stereotypic motor reaction to pain and absence of cranial nerve reflexes were reliable predictors of poor outcome, but this
