Popular Abstract in Swedish Växter får energi att växa till och fortplanta sig genom fotosyntes och cellandning. Vid fotosyntesen använder växterna ljusenergin från solen medan vid cellandningen kolföreningar bryts ner för att frigöra den energi som behövs till olika kemiska processerna i cellen. Enzymer är proteiner som katalyserar dessa kemiska processer. För att omvandla ett utgångsämne (t ex sMost cells are crowded with solutes, enzymes, nucleic acids, structural proteins and membranes. Crowding promotes macromolecular interactions and determines major properties of the cellular environment such as viscosity, diffusion and inhomogeneity. Macromolecular interactions that involve enzymes can affect the kinetic and regulatory properties of these, hence the interactions are part of the met

Hemicellulosic materials are among the most abundant renewable resources on earth, but have not yet found any broad application. However, if a cost effective extraction method is developed, hemicelluloses have the potential to be utilized to a much larger extent in the future. Ultrafiltration (UF) is a low energy demanding separation process that can be used to concentrate and purify hemicellulose

In addition to its well-known hematopoietic effects, erythropoietin (EPO) also has neuroprotective properties. However, hematopoietic side effects are unwanted for neuroprotection, underlining the need for EPO-like compounds with selective neuroprotective actions. One such compound, devoid of hematopoietic bioactivity, is the chemically modified, EPO-derivative carbamylerythropoietin (CEPO). For c

Popular Abstract in Swedish I denna avhandling diskuteras olika aspekter av tillverkning av nanostrukturer med nanoimprint litografi (NIL). Detta är en relativt ny metod som möjliggör snabb tillverkning av högupplösta strukturer på stora ytor. För att skapa dessa strukturer med NIL använder man sig av mekanisk deformation av mönstringsmaterialet. Detta skiljer sig från de mer etablerade mönstringsThis thesis describes different aspects of nanotechnology manufacturing with nanoimprint lithography (NIL), a relatively new nanofabrication tool capable of high resolution and high throughput. Surface structure creation with NIL is based on mechanical deformation of the patterning material. This is radically different from the two main established methods, ultra violet lithography (UVL) and elect

BACKGROUND AND PURPOSE: The etiology of subarachnoid hemorrhage (SAH) is poorly understood. Reduced lung function, expressed as low forced expiratory volume in 1 second (FEV(1)) and low forced vital capacity (FVC), is a predictor of cardiovascular disease, but whether reduced lung function is a risk factor for SAH is not known. The association between lung function and incidence of SAH was invest

Duchenne muscular dystrophy (DMD) is the most common childhood myopathy, characterized by muscle loss and cardiorespiratory failure. While the genetic basis of DMD is well established, secondary mechanisms associated with dystrophic pathophysiology are not fully clarified yet. In order to obtain new insights into the molecular mechanisms of muscle dystrophy during earlier stages of the disease, we

Autoantibodies against glutamic acid decarboxylase (GAD65Ab) are used in the classification of diabetes in adults. We assessed the concordance in GAD65 autoantibody levels within subjects between three different GAD65Ab radio binding assays (RBA). Plasma samples from 112 diabetes patients (median age 50 years) initially classified with type 2 diabetes was randomly selected from a local diabetes re

Black liquor is a side-stream in the production of kraft pulp. The extraction of lignin and hemicelluloses from black liquor would reduce the load on the recovery boiler and give valuable by-products. Lignin was separated from black liquor by membrane filtration, using one ceramic and three polymeric nanofiltration membranes, with molecular weight cut-offs in the range of 200 Da to 1 kDa. Ultrafil

Objectives: Evaluate if socioecological and biological factors, at the age of 8 years, are associated with lower level of physical activity (PA) 2 years later. Method: In a study cohort of 199 children aged 7.8±0.6 years, we used questionnaires and physical measurements to evaluate biological (eg, sex), social (eg, parental PA) and environmental (eg, school settings) factors. Objective PA was meas

BACKGROUND: The incidence of skin diseases in children is influenced by hereditary, social, and environmental factors. The objective of this study was to determine the incidence of pediatric dermatoses at a University Hospital in Northern Greece.PATIENTS AND METHODS: We reviewed epidemiologic data of 940 patients, aged 0-18 years, who were referred to the outpatient clinic of a University Hospital

A search for flavour-changing neutral current decays of a top quark into an up-type quark (q = u, c) and the Standard Model Higgs boson, t → Hq, is presented. The search is based on a dataset of pp collisions at s = 13 TeV recorded in 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider and corresponding to an integrated luminosity of 36.1 fb−1. Two complementary analyses are pe

A series of quinone-based compounds were tested for their ability to act as external electron acceptors in the 1-dehydrogenation of-αmethyl-hydrocortisone-21-acetate, with polyurethane-entrapped Arthrobacter simplex cells in buffer-saturated n-decan-1-ol. This organic solvent was needed to solubilize the steroid substrate. In aqueous medium, the conversion with free cells virtually stopped after o

1. The effects of various neuropeptide Y (NPY) and peptide YY (PYY) fragments on electrically-evoked twitches in the rat isolated vas deferens were studied and compared with the effects of full length NPY and PYY. The aim was to identify the shortest NPY/PYY fragments that are capable of suppressing the contractions. 2. NPY (1-36) and C-terminal fragments of NPY (from 11-36 to 22-36) suppressed th

Objective: To compare long term outcome between childhood-onset Anorexia Nervosa (AN) and low-weight Avoidant/Restrictive Food Intake Disorder (ARFID) in regard to psychiatric diagnoses, social and occupational functioning. Method: A consecutive series of 56 children originally treated for low-weight restrictive eating disorder (ED) were followed up after a mean of 15.9 years. ARFID-diagnoses were

This paper introduces a surface model with two soil-layers for use in a high-resolution circulation model that has been modified with an extrapolated surface temperature, to be used for the calculation of turbulent fluxes. A quadratic temperature profile based on the layer mean and base temperature is assumed in each layer and extended to the surface. The model is tested at two sites on the Tibeta

Xylose forms the direct carbohydrate-protein link in extra- or pericellular proteoglycans (PGs) that are substituted with either chondroitin sulfate (CS)/dermatan sulfate (DS) and/or heparan sulfate (HS). Cell surface PGs carrying HS are important regulators of cell growth. Xylose coupled to an aromatic compound can enter cells and initiate either CS/DS synthesis or both HS and CS/DS synthesis, de

In very recent years, growing efforts have been devoted to the development of all-polymer solar cells (all-PSCs). One of the advantages of all-PSCs over the fullerene-based PSCs is the versatile design of both donor and acceptor polymers which allows the optimization of energy levels to maximize the open-circuit voltage (Voc). However, there is no successful example of all-PSCs with both high Voc

BACKGROUND AND OBJECTIVES: The aims of this multi-institutional study were to assess the feasibility of iterative cytoreductive surgery (iCRS)/hyperthermic intraperitoneal chemotherapy, iCRS in colorectal peritoneal carcinomatosis (CRPC), evaluate survival, recurrence, morbidity and mortality outcomes, and identify prognostic factors for overall survival.METHODS: Patients with CRPC that underwent
