Background: Podocalyxin-like 1 (PODXL) is a cell-adhesion glycoprotein and stem cell marker that has been associated with an aggressive tumour phenotype and adverse outcome in several cancer types. We recently demonstrated that overexpression of PODXL is an independent factor of poor prognosis in colorectal cancer (CRC). The aim of this study was to validate these results in two additional indepen
Katalysatorer påskyndar en reaktion utan att själva förbrukas; denna mening känner nog många igen från sin skoltid. Andra har hört talas om katalysatorer som något de "har i bilen". Mycket riktigt är det främst i bilar där vi i våra vardagliga liv stöter på katalysatorer. Här används de för att omvandla de mycket giftiga gaserna kolmonoxid och kväveoxid till för människorna ofarligt kvävIn order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. Planar Lase
Quantification using the Centiloid (CL) scale has become a valuable information to consider when interpreting amyloid-PET images and is now implemented in several software packages. This work aims to assess the comparability of CL from [18F]flutemetamol scans derived using several research and commercial quantification pipelines. Methods: This analysis relies on three datasets: a test-retest cohor
BACKGROUND: Long COVID has emerged as a global health challenge, with increasing evidence of cardiovascular sequelae. Most previous studies have focused on hospitalised cohorts, whereas cardiovascular risk in community-managed long COVID cases remains less explored. We aimed to investigate the incidence of major cardiovascular events in individuals with long COVID compared to those without long CO
Forests form the backbone of the European terrestrial carbon sink (State Forest Service & Ministry of Environment, 2018). As the European Union (EU) strives to become climate neutral by 2050, forests are accounted for the natural carbon absorption mechanism (European Commission, n.d.). Currently, the European net land carbon sink is decreasing largely due to forest ageing (Pilli et al., 2022),
The transition from animal-based to plant-based proteins is rapidly increasing because of different concerns about meat consumption, some being the nutritional and environmental effects of meat consumption. During this transition, there needs to be a holistic approach to assessing plant-based food. This master thesis is focused on investigating the nutritional and environmental impact of three pla
Background The two main functional goals of postural control are postural stability (balance) and postural orientation. Postural orientation is the ability to maintain alignment between body segments and the environment during a static or dynamic activity. Nae et al. have evaluated the measurement properties of a clinical test battery for assessing postural orientation errors (POEs) in patients wi
Att förutsäga framtiden – modellering som ett verktyg för att förutsäga vattenkvantitet och vattenkvalitet Inom 100 år så kommer klimatet förändrats avsevärt om utsläpp av växthusgaser fortsätter i samma takt som idag. Detta kommer påverka temperatur, nederbörd vilka i sin tur påverkar flödet av vatten i Sverige. Ett avrinningsområde består av olika jordtyper, vegetation och topografi, vilka allClimate change will alter the hydrological cycle in the 21st century with implications for the water balance and water quality. As characteristics of the landscape may vary significantly between nearby locations, hydrological models need to be able to delineate responses attributed to specific landscape characteristics, to estimate their responses to altered climatic drivers. Small streams are the
This master thesis project was performed in collaboration with Johnson Matthey. Johnson Matthey is a worldwide company working with sustainable technologies. The site in Perstorp, where this work was performed, focus on formaldehyde production. In order to continuously improve chemical processes, simulation and modeling are advantageous tools. They can give a better understanding of the processes
This thesis explores the implementation and acceptability of blanket (population-wide coverage of active case finding and prevention) Post-Exposure Prophylaxis (PEP) as a preventive measure for leprosy transmission in the Achham district of Sudurpaschim (Far-west) Province in Nepal. Leprosy remains a significant public health concern in Nepal, with persistent challenges in prevention and control e
Recent global warming trends, particularly in the arctic regions and Himalayas are modifying forest structure and function, notably biogeographical changes in tree species distribution together with alteration in Net Primary Production (NPP), Leaf Area Index (LAI) and Carbon biomass. These alterations are most pronounced in mountain environments, carrying significant impacts on woody species which
Objective: Transcatheter valve-in-valve implantation has emerged as an option, in addition to reoperative surgical aortic valve replacement, to treat failed biologic heart valve substitutes. However, the clinical experience with this approach is still limited. We report the comprehensive experience of transcatheter valve-in-valve implantation in the Nordic countries from May 2008 to January 2012.
Purpose: To assess the additional value of subtraction ictal single-photon emission computed tomography (SPECT) coregistered to MRI (SISCOM) for localization of the epileptogenic zone in patients with drug-resistant epilepsy scheduled for invasive video-EEG (VEEG) before epilepsy surgery by a descriptive study from clinical practice. Methods: Forty-nine consecutive epilepsy patients between Januar
Background: The aim of this study was to examine in elderly men a relationship between depressive symptoms, peripheral vascular disease and cerebral blood flow (CBF). Methods: Population-based cohort study started with an examination of 809 men at age 55, followed by the first (age 68ys) and second follow up (age 82ys). 128 survivors were examined at age 82 with Tc-99m-HMPAO-SPECT to estimate CBF,
We assessed hepatocellular carcinoma (HCC) risk associated with smoking and alcohol consumption and their interactions, using both questionnaire data and objective serum biomarkers. Information on smoking and alcohol consumption was collected at baseline from 450,112 participants of the EPIC cohort, among whom 255 developed HCC after a median follow-up of 14 years. In a nested case–control subset
Aircraft observations of precipitating clouds with cloud top temperatures higher than -38°C have revealed that Secondary Ice Production (SIP) is responsible for presence of majority of ice particles. One such SIP mechanism is fragmentation via collisions between ice particles. The central theme of this study is to understand the dependencies of this SIP mechanism and improve its existing numerical
Popular Abstract in Swedish Esofagektomi (kirurgiskt avlägsnande av matstrupen) är ett omfattande ingrepp som främst utförs pga cancer, men som även utförs vid vissa godartade sjukdomar. Matstrupen sträcker sig från svalget, via bakre delen av bröstkorgen ned till övre delen av buken. Det anatomiska läget gör att man ur kirurgisk synpunkt oftast måste avlägsna matstrupen via en kombination av inciIn a prospective randomised study following oesophagectomy and gastric tube reconstruction patients with hand-sutured neck anastomoses were compared with patients with circular stapled chest anastomoses. The two groups had equal rates of anastomotic or conduit leaks of 7.3 % (3/41) and 7.1 % (3/42) and of benign anastomotic strictures of 19.5 % (8/41) and 28.6 % (12/42). Another prospective random
