Background. Airborne SARS-CoV-2 plays a prominent role in COVID-19 transmission. Numerous studies have sampled air from patient rooms, but airborne spread to other hospital areas such as corridors is less investigated. Methods. Size-fractionated aerosol particles were collected weekly, with 12 hours of sampling time daily, in corridors at two infectious disease wards in southern Sweden between Mar
Peptides representing the C-terminal end of secretin were synthetized and their effects tested along with secretin on column-perifused isolated mouse pancreatic islets. Insulin release induced by 10 mmol/l D-glucose was potentiated by secretin tested in a concentration range of 0.01-10 μg/ml; the maximal effect was obtained with 1 μg/ml secretin. This effect was mimicked by 50-500 μg/ml NH2-Leu-Le
Blood mononuclear cells obtained from 17 newly diagnosed insulin-dependent diabetic (IDDM) patients treated with insulin for 5-7 days were assessed for the number of spontaneous and pokeweed mitogen (PWM)-stimulated immunoglobulin-secreting cells in a reverse haemolytic plaque assay. The spontaneous in vitro immunoglobulin secretion was evanescent and decreased in individual patients within 1-4 mo
This master thesis is commissioned by the company Haldex Brake Products AB based in Landskrona. The company is acting on the road vehicle market. Amongst other products the company produces disc brakes for the heavy road vehicle industry. Disc brakes developed by Haldex, based on the sliding caliper principle, are during certain circumstances experiencing problems with malfunction of the brake due
Neurogenesis in the adult mammalian brain is well studied, in the two main regions subventricular zone (SVZ) and subgranular zone (SGZ), under different physiological and pathological condition. Recent studies also revealed newly formed neurons in other parts of the brain including the hypothalamus. However, how robust neurogensis in this area is, is still unclear. In this study we used a novel re
Author: Ebba Eiroff Title: Students narratives of loneliness Supervisor: Kristina Göransson Assessor: Mats Hilte The aim for this qualitative study was to examine university students experiences of loneliness based on Erving Goffman’s dramaturgy theory, together with the conceptions of normality, shame and guilt. How students describe feelings of loneliness and how they relate their experiences t
The purpose of the study was to investigate how companies can harness the power of social media by utilizing Social CRM. It was investigated how integrating social media channels into existing Client Relationship Management platforms can influence customer service and customer loyalty. A mixture of both qualitative and quantitative research methods with an abductive approach was used. The researc
Trots att kunskaperna om och intresset för smärta och smärtlindring har ökat de senaste åren drabbas fortfarande många patienter en inadekvat smärtlindring och många patienter förväntar sig smärta postoperativt. Syftet med denna studie var att undersöka kvinnor i olika åldrar avseende förväntningar och upplevelser av postoperativ smärta och smärtlindring samt hur stor betydelse den preoperativa in
The objective of the present work is to, in a single material, combine a number of molecular design strategies that have proven successful in the preparation of high-performance anionexchange membranes (AEMs) for alkaline fuel cells. Hence, we here report on highly conductive and alkali-stable poly(phenylene oxide)s carrying flexible side chains attached via alkyl spacer units, where each side cha
In this study, effects of a dust hole and its location on the flow structure, endwall heat transfer and friction factor in a U bend channel used for a gas turbine blade tip cooling are numerically studied. The dust hole is placed on the endwall of a U bend at different locations. The U bend channel without dust hole is considered as Baseline. The Reynolds number ranges from 50,000 to 440,000. Resu
In the present study, wild type and three mutants of pyranose 2-oxidase (PyOx-WT, PyOx-MT1, PyOx-MT2, PyOx-MT3), which showed improved properties for D-galactose oxidation, were investigated for their oxidising ability when immobilised on graphite electrodes. Four different flexible Os polymers with formal potentials ranging between −0.140 and 0.270 V vs. Ag|AgCl0.1 M KCl were applied together wit
Background: Early hospital arrival and rapid intervention for acute myocardial infarction is essential for a successful outcome. Several studies have been unable to identify explanatory factors that slowed decision time. The present study examines whether personality, psychosocial factors, and coping strategies might explain differences in time delay from onset of symptoms of acute myocardial infa
Background: To study the diabetes related CVD risk between men and women of different ages. Methods: Hazards ratios (HRs) (95%CI) for acute CHD and ischaemic stroke events were estimated based on data of Finnish and Swedish cohorts of 5111 women and 4167 men. Results: 182 (3.6%) women and 348 (8.4%) men had CHD and 129 (2.5%) women and 137 (3.3%) men ischaemic stroke events. The multivariate adjus
In this overview the technique of accelerator mass spectrometry (AMS) and its use are described. AMS is a highly sensitive method of counting atoms. It is used to detect very low concentrations of natural isotopic abundances (typically in the range between 10(-12) and 10(-16)) of both radionuclides and stable nuclides. The main advantages of AMS compared to conventional radiometric methods are the
The role of nitric oxide (NO) in migraine has been studied in the experimental glyceryl trinitrate (GTN)-infusion headache model. We hypothesized that GTN-induced headache may activate the trigeminovascular system and be associated with increased levels of sensory neuropeptides, including calcitonin gene-related peptide (CGRP). CGRP, vasoactive intestinal peptide (VIP), neuropeptide Y (NPY) and so
Background: Plasma use has increased since studies have suggested that early treatment with blood components in trauma with severe hemorrhage may improve outcome. Plasma is also commonly used to correct coagulation disturbances in non-bleeding patients. Little is known about the effects of plasma transfusion on plasma volume. We report a prospective interventional study in which the plasma volume-
