Magnetkameran används vanligen för att generera anatomiska bilder som används vid diagnostik av olika sjukdomstillstånd. Normala anatomiska bilder avspeglar magnetresonanssignalens (MR-signalens) magnitud, vilket är signalvektorns längd. Denna är proportionell mot bl.a. antalet vätekärnor i varje volymselement. Ett annat sätt att använda MR-signalen är att skapa en bild av signalvektorns fasvinkelIntroduction: The main purpose of this study was to extract global values of oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen (CMRO2) in healthy volunteers, using magnetic resonance imaging (MRI) phase maps. The repeatability of the method was evaluated, and the age dependences of OEF and CMRO2 were analyzed. Material and methods: Phase data were acquired using a 3T MRI scann

Miljöpåverkan är ett ständigt återkommande ämne i samhällsdebatten. Många företag strävar efter att minimera sin miljöpåverkan, vilket kan ske genom att återanvända material i stället för att producera nya. I fallet med betongproduktion finns det flera sätt att göra den bättre för miljön. Till exempel kan rivningstegel användas som alternativ till den traditionella ballasten, som ett sätt att minsEnvironmental impact is a recurring topic in the social debate. Many companies strive to minimize their environmental impact, which can be done by reusing materials instead of producing new ones. In the case of concrete production, there are several ways to make it better for the environment. For example, brick waste can be used as an alternative to the traditional stone aggregate as a way to redu

The triple planetary crisis exerts high pressure on countries to transform their current economic system. The transition to a green economy is not only necessary to ensure sustainable development but also essential for countries to remain economically competitive. The neighbouring countries Panama and Costa Rica are both facing significant challenges under the green transition, despite their diffe

I dagens digitaliserade samhälle möter utgivare och publicister av traditionellt tryckt media stora ekonomiska motgångar vid försäljningen av exempelvis nyhetstidningar eller andra tidskrifter. Således har majoriteten av utläggare idag gjort sina publikationer tillgängliga för läsare online. De digitala intäkterna lyckas dock inte väga upp för de förluster utgivarna lider av den nedåtgående försälIn today's digitized society, publishers of legacy printed media face major financial hardships in the sale of newspapers and other magazines. Thus, most publishers today have made their publications available to readers online. However, digital revenues do not make up for the losses that the publishers suffer from the decreasing sales of printed media. This can in part be attributed to the fa

En ny underfamilj av cellulära vakter i växter Heterologt överuttryck av proteiner innebär att en gen som kodar för ett protein uttrycks i en annan värdorganism som normalt inte har den genen i sin arvsmassa. Inom biokemisk forskning är detta en viktig metod för att kunna studera proteiners struktur och funktion. Tyvärr kan uttrycket av en främmande gen medföra skador på värdorganismens celluläraHeterologous overexpression of proteins signifies that the encoding gene of a protein in one organism is expressed in another host organism that normally does not have that gene in its genome. In basic biochemical research, this is an important method for studying various protein functions such as activity and interactions in biological processes, as well as obtaining sufficient amounts to determi

There is strong evidence that climate change has a direct impact on humans and extreme temperatures have been linked to negative health impacts and increasing mortality. The heat wave of 2018 caused up to 8.2% more deaths compared to the year before in Sweden, with higher impacts in other parts of the world. The fact that people spent almost 90% of their times indoors makes the indoor environment

The main monitoring method during labor is cardiotocography, CTG, which measures the fetal heartbeat, FHR, as well as the uterine contractions, TOCO. The CTG is a valuable tool in assessing the fetal status and it is evaluated intermittently by clinicians during the progress of the labor. However, abnormalities in the CTG are often non-specific which makes the interpretation difficult and inconsis

The aim of this thesis is to design two patch antenna arrays for dual-frequency harmonic radar application, one for the transmitter and the other for the receiver. The arrays are used to track the Bogong moth that migrates from the countryside to the Australian Alps during spring. The tracking is done at the radar by operating the transmitter at one frequency and the receiver at twice the frequenc

Lifestyle modifications could be crucial in preventing and managing type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVD), including diet and postprandial glycaemic control. Previous studies on the effects of polar lipids (PLs) on postprandial metabolic responses at Lund University have shown conflicting results. To reconcile these findings and contribute to the existing literature, th

Background: The impact of surgical specialization on long-term survival in patients undergoing emergent colon cancer resections remains unclear. Method: A retrospective analysis was conducted on all patients who underwent emergent colon cancer resections at a secondary care hospital between 2010 and 2020. The most senior surgeon performing the procedures was classified as colorectal surgeon (CS) o

Climate warming is expected to influence the prevalence of vector-transmitted parasites. Understanding the extent to which this is ongoing, or has already occurred, requires empirical data from populations monitored over long periods of time, but these studies are sparse. Further, vector-disease research involving human health is often influenced by disease control efforts that supersede natural t

BACKGROUND AND AIMS: Adhering to the EAT-Lancet diet has been observed to be associated with lower risks of various morbidities. This study aimed to investigate the association of adhering to the EAT-Lancet diet with incident chronic obstructive pulmonary disease (COPD) and identify plasma proteins mediating such association.METHODS: This prospective study involved 202 340 participants free of COP

PURPOSE: To assess the risk of self-fulfilling prophecy from withdrawal of life-sustaining therapy (WLST) in comatose cardiac arrest patients undergoing neuroprognostication.METHODS: Post-hoc multicentre study matching adults resuscitated from out-of-hospital cardiac arrests, in WLST-permitting cohorts (TTM and TTM2), and non-WLST-permitting cohorts (KORHN and ProNeCA). We matched patients in a 1:

Background: Racial differences in metastatic castration-resistant prostate cancer (mCRPC) genomes have not yet been fully studied. We aimed to investigate transcriptomic, mutational, and clinical differences by race in a large multi-institutional cohort of men with mCRPC. Methods: Genomic and clinicopathologic data from four mCRPC tumor biopsy cohorts were obtained and aggregated. Gene set enrichm

Introduction Systemic inflammation is postulated to mediate heat stroke and heat-related organ injury, yet acute inflammatory responses among heat-stressed workers remains poorly understood. We aimed to describe neutrophil mobilisation and potential release of DNA during heat stress in multiple hot occupational settings and a controlled experimental setting. Methods Neutrophil:lymphocyte ratio (NL

Objectives: Panax ginseng (P. ginseng, C.A. Meyer) is suggested to improve blood glucose regulation, but evidence remains inconsistent. We examined whether consuming P. ginseng as a preload before a carbohydrate-rich meal modulates postprandial glucose and insulin responses. Methods: In a randomized, double-blind, crossover trial, 22 healthy middle-aged adults consumed P. ginseng tablets containin

The longitudinal and multidisciplinary research project Malmö Youth Sport Study measured the sports results achieved by two cohorts of pupils using a variable named ACHIEVE, dividing the pupils into three categories (an elite group competing at the national or international level, a group competing at the district level, and a third group either not competing at all or below district level). This

Strukturella och petrologiska studier av komplext veckade mafiskt- och felsiskt varvade sekvenser har genomförts i den paraautoktona delen av Svekonorvegiska provinsen i sydvästra Sverige. Tre deformationsfaser (D1, D2, D3) innefattande minst två veckfaser (F2, F3) och två lineationsfaser (L2, L3) karakteriserar ett flerfasigt veck i migmatiserad och mycket kompetent granatamfibolit. Denna enhet vStructural and petrological studies on complexly folded mafic and felsic layered sequences have been mapped in the parautochthonous basement of the Sveconorwegian Province, Sweden.

Background: Cognitive impairment in trauma-affected refugees is often unassessed due to the absence of suitable cross-cultural neuropsychological measures, the high prevalence of psychiatric symptoms, and the need for interpreter mediation. This poses both a clinical challenge and a health inequality for trauma-affected refugees who are left without access to much needed rehabilitation. Untreated
