Laccases are multicopper oxidases capable of oxidizing a broad range of phenolic and non-phenolic compounds, making them attractive biocatalysts for lignin valorization and environmental applications. In this work, two bacterial laccases, LacA from Bacillus amyloliquefaciens and MEK from Psychrobacter sp., were recombinantly produced in Escherichia coli BL21 (DE3), purified, and characterized to s
Various factors may impact the process of reading. The depth of the orthography influences the reading strategy for readers of shallow and deep orthographies because the complexity of the mapping between graphemes and phonemes increases with depth. In this thesis, reading comprehension in Danish, considered a deep orthography, is examined. While phonological awareness is commonly recognized as an
Neuronal ceroid lipofuscinoses (NCLs) represent a large group of inherited neurodegenerative disorders characterized by an abnormal accumulation of lipopigment in neuronal and extraneuronal cells. The authors present a case of juvenile neuronal ceroid lipofuscinosis in a 7-year-old boy. Ultrastructural examination of a skin biopsy disclosed deposits of curvilinear profiles and fingerprint-like str
The main focus in this licentiate thesis is a description of the environmentally introduced action of diffusing and chemically reactive (e.g. carbonation and chemical-physical adsorption-desorption) matter in the pore solution and in the air-filled space in the pore system of the material. The governing equations describing the variation of concentrations of different substances and temperature wi
A diagnosis-antibiotic prescribing study was performed in 5 counties in Sweden during 1week in November in the y 2000 and 2002, respectively. As part of the study, the characteristics and clinical management of patients who received diagnoses of urinary tract infections (UTIs) ( n = 1564) in primary care, were analysed. 85% of the visits were by women, and 74% of all consultations were diagnosed a
Background: Termites of the subfamily Macrotermitinae live in a mutualistic symbiosis with basidiomycete fungi of the genus Termitomyces. Here, we explored interaction specificity in fungus-growing termites using samples from 101 colonies in South-Africa and Senegal, belonging to eight species divided over three genera. Knowledge of interaction specificity is important to test the hypothesis that
Exterior letter pairs (e.g., d_k in dark) play a major role in single-word recognition, but other research (D. Briihl & A. W. Inhoff, 1995) indicates no such role in reading text. This issue was examined by visually degrading letter pairs in three positions in words (initial, exterior, and interior) in text. Each degradation slowed reading rate compared with an undegraded control. However, whe
The individual of a species is the basic unit which responds to climate and UV-B changes, and it responds over a wide range of time scales. The diversity of animal, plant and microbial species appears to be low in the Arctic, and decreases from the boreal forests to the polar deserts of the extreme North but primitive species are particularly abundant. This latitudinal decline is associated with a
Pineal evolution is envisaged as a gradual transformation of pinealocytes (a gradual regression of pinealocyte sensory capacity within a particular cell line), the so-called sensory cell line of the pineal organ. In most non-mammals the pineal organ is a directly photosensory organ, while the pineal organ of mammals (epiphysis cerebri) is a non-sensory neuroendocrine organ under photoperiod contro
Three healthy young male subjects were given a single load of ethanol (approximately 3 g/kg body weight) over 5 hours. Liver aspiration biopsies were performed at the start of the experiment and 6, 14, 24, and 48 hours after the start. Blood alcohol and serum transaminase activity levels were measured simultaneously. Triglycerides and phospholipids of the liver biopsy material were determined by a
Increased intraluminal pressure of the rat portal vein in vivo causes hypertrophy and altered contractility in 1 to 7 days. We have used organ cultures to investigate mechanisms involved in this adaptation to mechanical load. Strips of rat portal vein were cultured for 3 days, either undistended or loaded by a weight. Length-force relations were shifted toward longer length in stretched cultured v
We studied the effect of hyperbaric oxygen treatment on axonal outgrowth in grafts of sciatic nerves in 40 rats. The sciatic nerve was transsected and a 10 mm long segment from the opposite side was immediately sutured in as a nerve graft. Postoperatively 17 animals were treated with 100% oxygen at 3.2 atmospheres absolute pressure for 45 minutes and the treatment was repeated at four and eight ho
