Clinical course and mortality by etiology of liver cirrhosis in Sweden : a population based, long-term follow-up study of 1317 patients

Background: Liver cirrhosis is characterized by a silent phase until decompensation, which is defined by ascites, bleeding from esophageal varices or hepatic encephalopathy. Aim: We compare the clinical course, patterns of survival and causes of death by etiology during long-term follow-up in a large population-based cohort of patients with incident cirrhosis. Material and methods: We used populat

A method for calculating contact pressure and tip contact in spur gear sets with manufacturing errors

To investigate how manufacturing errors affect the gear set, a method is developed to calculate the contact stress of a gear set with pitch and involute incline errors. The method is parametric, and a hybrid model is used to model the gear stiffness. Contact outside the line of action is considered.A numerical example is used to show how manufacturing errors can change the contact pressure and cau

Continuous glucose monitoring in pregnant women with type 1 diabetes : an observational cohort study of 186 pregnancies

Aims/hypothesis: The aim of this study was to analyse patterns of continuous glucose monitoring (CGM) data for associations with large for gestational age (LGA) infants and an adverse neonatal composite outcome (NCO) in pregnancies in women with type 1 diabetes. Methods: This was an observational cohort study of 186 pregnant women with type 1 diabetes in Sweden. The interstitial glucose readings f

Activation of immune responses against the basement membrane component collagen type IV does not affect the development of atherosclerosis in ApoE-deficient mice

Oxidation of low-density lipoprotein (LDL) in the arterial extracellular matrix results in malondialdehyde (MDA)-modifications of surrounding matrix proteins. We have recently demonstrated an association between high levels of autoantibodies against MDA-modified collagen type IV and risk for development of myocardial infarction. Collagen type IV is an important component of the endothelial baseme

18 F-Flortaucipir in TDP-43 associated frontotemporal dementia

Retention of 18 F-Flortaucipir is reportedly increased in the semantic variant of primary progressive aphasia (svPPA), which is dominated by TDP-43 pathology. However, it is unclear if 18 F-Flortaucipir is also increased in other TDP-43 diseases, such as bvFTD caused by a C9orf72 gene mutation. We therefore recruited six C9orf72 expansion carriers, six svPPA patients, and 54 healthy controls. A

Mapping of apparent susceptibility yields promising diagnostic separation of progressive supranuclear palsy from other causes of parkinsonism

There is a need for methods that distinguish Parkinson’s disease (PD) from progressive supranuclear palsy (PSP) and multiple system atrophy (MSA), which have similar characteristics in the early stages of the disease. In this prospective study, we evaluate mapping of apparent susceptibility based on susceptibility weighted imaging (SWI) for differential diagnosis. We included 134 patients with PD,

Moonlighting of Haemophilus influenzae heme acquisition systems contributes to the host airway-pathogen interplay in a coordinated manner

Nutrient iron sequestration is the most significant form of nutritional immunity and causes bacterial pathogens to evolve strategies of host iron scavenging. Cigarette smoking contains iron particulates altering lung and systemic iron homeostasis, which may enhance colonization in the lungs of patients suffering chronic obstructive pulmonary disease (COPD) by opportunistic pathogens such as nontyp

Design, Synthesis and Thermodynamic Studies of Galectin Ligands

The word “medicine” has its origin from the Latin word medeor or medicor, which means to heal or to cure. Since ancient times, medicines helped to soothe the pain, which eventually resulted in general improvement of life. In a course of a lifetime, the use of medicines can vary according to the necessity. We can have medicines, or drugs, for most of the diseases, and for many others the available The signaling within and between cells in biology is governed by molecular recognition between natural or synthetic ligands and proteins. This thesis project aimed to investigate the thermodynamic properties of specific interaction between synthetic ligands and galectin proteins. The choice of galectins as model proteins resides in the availability of applicability in a full range of complementary

Large eddy simulation of an aerated Rushton stirred tank

Simulations of aerated stirred reactor is performed using Large Eddy Simulation (LES). The gas phase is modelled using Lagrangian Particle Tracking (LPT). The reactor is stirred by a single impeller Rushton turbine, centred in the reactor. The air is introduced at the bottom wall through a circular sparger. The main focus is to investigate how the gas phase affects the liquid in the reactor. Effec

Microscopic insight into non-radiative decay in perovskite semiconductors from temperature-dependent luminescence blinking

Organo-metal halide perovskites are promising solution-processed semiconductors, however, they possess diverse and largely not understood non-radiative mechanisms. Here, we resolve contributions of individual non-radiative recombination centers (quenchers) in nanocrystals of methylammonium lead iodide by studying their photoluminescence blinking caused by random switching of quenchers between acti

Norovirus epidemiology in community and health care settings and association with patient age, Denmark

Norovirus (NoV) is a major cause of gastroenteritis. NoV genotype II.4 (GII.4) is the predominant genotype in health care settings but the reason for this finding is unknown. Stool samples containing isolates with a known NoV genotype from 2,109 patients in Denmark (patients consulting a general practitioner or outpatient clinic, inpatients, and patients from foodborne outbreaks) were used to dete
