Anesthesiology is the medical specialty dedicated to the relief of pain and care of the surgical patient before, during and after surgery. Most of the work in anesthesiology is routine patient care, but because patients are sick and surgical procedures may develop in unexpected ways, anesthesiology by its nature often involves medical crises. In recent years, two concepts have gained increasing i

Idiopatisk normaltryckshydrocephalus (iNPH) är en neurologisk sjukdom som påverkar hjärnans vätskecirkulation och kan leda till symtom som gång- och balanssvårigheter, kognitiv nedsättning och urininkontinens. Sjukdomen drabbar omkring 1.5 % av 70-åringar, och prevalensen ökar med åldern. Det är en svårdiagnostiserad sjukdom där hjärnvätska (CSF) ansamlas i hjärnans hålrum, vilket påverkar hjärnanIntroduction: Idiopathic normal pressure hydrocephalus (iNPH) is a treatable but largely underdiagnosed neurological condition affecting the elderly population. It is characterised by gait and cognitive impairment, as well as urinary incontinence. For the most part, it is diagnosed via imaging and clinical assessments. Abnormalities in cerebrospinal (CSF) flow in the cerebral aqueduct have been li

Cancer kan drabba vem som helst och kan ha sitt ursprung i många olika områden i kroppen. Antalet nya cancerfall ökar varje år, men vissa typer av cancer har bättre prognos än andra. Den vanligaste cancertypen i Sverige är prostatacancer och den drabbar framför allt äldre män. Prostatacancer har god prognos och det finns effektiva metoder att helt bota prostat- acancer om den behandlas i ett tidigPurpose: Recent developments in external radiotherapy and its utilization with artificial in- telligence (AI) enables advanced treatment plans for a range of different disease sites. By adapting to the anatomy of the day, target coverage can be ensured while sparing more healthy tissue. The purpose of this project was to study the feasibility and benefits of daily cone beam computed tomography (CB

Today, we are creating and building more than ever. While buildings rise from the horizon, the consumption of building materials increases massively. More than 22% of global carbon dioxide emissions come from the consumption of building materials such as concrete, steel, and aluminum, etc. 55% of embodied carbon in a conventional building is in the structure and substructure (Smedley, 2019). Hence

Data-driven optimering en succé för skärande bearbetning Optimeringsmetod från maskininlärning mycket lovande vid användning för komplexa processer inom skärande bearbetning En otrolig mängd av industriell tillverkning idag förlitar sig på ett till synes enkelt koncept, att forma metall genom svarvning eller fräsning. Skärande bearbetning letar sin väg in i många industrier och alla sätt att ökThe purpose of this study was to investigate the applicability of data-driven experimental design for the optimization of a hard coating for cutting tools in metal machining. The complexity of metal machining leads to difficulty in theoretically modeling and understanding the interactions and correlations between parameters and performance. Because of this and the importance of incremental perform

Background: Aftermarket logistics is important for a manufacturing company to maintain customer satisfaction in the long run. However, the supply chain set for aftermarket parts is equally crucial as the original equipment. Modification or optimization of the logistics systems for slow-moving aftermarket items is inevitable. Sandvik, an engineering company in the mining industry is now interested

Purpose - Food lost or wasted constitutes a substantial environmental, economic and social problem; today roughly one-third of edible parts of food that is produced for human consumption globally gets lost or wasted. Thus, a reduction of waste would contribute to a sustainable use of resources. It has been highlighted that packaging development has the potential to play an important role in this p

The principal rule of the common market is that goods and services are able to move freely across the borders of Member States. State monopolies in control of supply and demand are, therefore, only under exceptional circumstances compatible with the conditions of the common market. The compatibility of Swedish State monopolies with EC law is a controversial matter. The case-law of the ECJ lets us

There is an urgent need for accurate and validated methods to measure plasma phosphorylated tau (p-Tau) biomarkers in Alzheimer’s disease (AD). In this study, we compared the performance of new commercially available plasma p-Tau217 assay developed by ALZpath to other established p-Tau assays in an autopsy-confirmed sample. We included 72 participants from the Arizona Study of Aging and Neurodegen

Background: Disorders affecting the nervous system are diverse and include neurodevelopmental disorders, late-life neurodegeneration, and newly emergent conditions, such as cognitive impairment following COVID-19. Previous publications from the Global Burden of Disease, Injuries, and Risk Factor Study estimated the burden of 15 neurological conditions in 2015 and 2016, but these analyses did not i

Before performing 177Lu-DOTATATE therapy for neuroendocrine tumors, somatostatin receptor (SSTR) PET imaging is currently used to confirm sufficient tumor SSTR expression, but it also has potential to be used to personalize treatment by predicting absorbed doses to critical organs. This study aims to validate the predictive capability of SSTR PET in anticipating renal absorbed dose in the first cy

Evidence from neuropathological cohorts indicates that a CSF α-synuclein (α-syn) seed amplification assay (SAA) might provide quantitative kinetic parameters correlating with α-syn pathology burden in patients with Lewy body disease (LBD). Studies are needed to assess their longitudinal trend during the presymptomatic and clinical disease phases and their correlation with measures of disease progr

Background: Thrombolysis is a common method in the treatment of lower extremity bypass graft occlusion. The purpose of this study was to investigate the results of thrombolytic therapy in the management of acute bypass graft occlusion and to identify risk factors for technical failure and amputation. Methods: All patients at two tertiary referral centers undergoing thrombolysis for acute graft occ

The presented thesis work is concerned with the study of molecular dynamics using liquid nuclear magnetic resonance (NMR) spectroscopy. Spin relaxation dispersion experiments in the rotating frame (R_1ρ) are employed to provide a detailed, atomic-resolution view of protein dynamics. Comprehensive investigations of ¹⁵N backbone and ¹³C methyl side-chain confor

BACKGROUND: The use of nitrous oxide (N2O) during hemodilution has been questioned. Nitrous oxide reduces the inspired oxygen fraction (F1O2), depresses myocardial function and may reduce cardiac output (CO) and systemic oxygen delivery (DO2SY). The aim of this study was to evaluate the importance of the effects of nitrous oxide on systemic and myocardial circulation and oxygenation during extreme

Cross-sectional studies have associated obesity and other components of the so-called metabolic syndrome with low-grade inflammation. The temporal and causal relations of this association have not been fully explored. This study explored whether elevated levels of inflammation-sensitive plasma proteins (ISPs) (fibrinogen, orosomucoid, {alpha}1-antitrypsin, haptoglobin, and ceruloplasmin) are assoc

Background and objective: Human studies of arterio-venous (AV) differences in drug concentrations and the consequences for pharmacokinetic modelling and concentration-effect relationships are very limited. We therefore investigated the intravenous and intra-arterial concentrations of alcohol (ethanol) during the absorption, distribution and elimination stages of alcohol metabolism in healthy men.

OBJECTIVE: To study the pharmacodynamics of amoxicillin/clavulanic acid against different strains of Haemophilus influenzae in an in vitro kinetic model. The concentrations used corresponded to human serum levels obtained after 875 mg amoxicillin/clavulanic acid given b.i.d., 500/125 mg amoxicillin/clavulanic acid given t.i.d. and those obtained with a pharmacokinetically enhanced formulation cont

Popular Abstract in Swedish Levande organismer, inklusive människor, har en 14C/12C-kvot som återspeglar miljön. När materialet dör slutar kroppen att fylla på 14C och kroppens 14C börjar sönderfalla till 14N. Detta gav upphov till den klassiska 14C-dateringsmetoden, vilken utvecklades av professor W.F. Libby, 1949 och gav honom Nobelpriset i kemi 1960. 14C-datering används huvudsakligen inom arkeThe testing of nuclear weapons in the atmosphere, in the middle of the 20'h century, resulted in a bomb-pulse excess of atmospheric 14C. A bomb-pulse dating method was thus developed. The latter is a method to determine the time of formation of formerly living modern (i.e. living after 1955) material , based on the 14C/ 12C ratio in it. The objective of this work was to evaluate the factors that c
