Kvaliteten på kliniska bilder har stor betydelse för korrekt medicinsk diagnostik. I konventionella morfologiska MR-bilder är signalen normalt relativt hög i förhållande till bruset. Vissa nya MR-metoder för s.k. funktionsdiagnostik bygger emellertid på en avsiktlig degradering av signalen för att vissa kvantitativa parametrar skall kunna beräknas. I sådana studier kan följaktligen signal-till-bruNoise is a well-known problem in many imaging modalities. In magnitude magnetic resonance images, obtained by quadrature detection, the associated Rician distribution of noise constitutes a further complication. This type of noise is especially problematic at low signal-to-noise ratio (SNR) regions. The Rician noise distribution causes a non-zero minimum signal in the image, often referred to as t

Exaggerated neutrophil activation and formation of neutrophil extracellular traps (NETs) are reported in systemic sclerosis (SSc) but its involvement in SSc pathogenesis is not clear. In the present study we assessed markers of neutrophil activation and NET formation in SSc patients in relation to markers of inflammation and disease phenotype. Factors promoting neutrophil activation in SSc remain

The present article analyses the relation between politics and historiography in communist Romania (1948- 1989). Since the beginning of the four-decades-long communist dictatorship, history has been turned into an ancillary discipline of the political discourse. The analysis of this peculiar kind of historiography starts from the processes that have determined its political nature and brought to i

Background: Around 70% of all ICU patients are treated with antibiotics whereas up to 30% are suggested as unnecessary. Measuring antibiotic consumption is a prerequisite to improving its use and the purpose of the present investigation was to explore the use of antibiotics in Swedish ICUs. Material and methods: Daily Defined Doses (DDDs) of antimicrobials delivered to Swedish ICUs, 2016–2018, wer

Purpose: Etoposide to standard R-CHOP is used for high-risk diffuse large B-cell lymphoma (DLBCL) in some countries. Due to the lack of randomized trials, a real-world data study using matching methods was used to test the potential effectiveness of R-CHOEP over R-CHOP. Patients and Methods: This study included patients from the Danish Lymphoma Register diagnosed between 2006 and 2020 at the age o

Background: Fentanyl is commonly administered for procedural pain management in preterm infants, but target concentrations have not yet been defined. Methods: To investigate pharmacokinetics (PK), -dynamics (PD), and -genetics (PG), 25 infants (gestational age 23.3–34.1 weeks) received a fentanyl dose before a skin-breaking procedure (0.5 µg/kg) or tracheal intubation (2 µg/kg). Four pain scales w

Rubella virus encodes a nonstructural polyprotein with RNA polymerase, methyltransferase, and papain-like cysteine protease activities, along with a putative macrodomain of unknown function. Macrodomains bind ADP-ribose adducts, a post-translational modification that plays a key role in host-virus conflicts. Some macrodomains can also remove the mono-ADP-ribose adduct or degrade poly-ADP-ribose ch

Background: Medication overuse headache is a prevalent secondary headache due to the overuse of analgesics, mainly over-the-counter analgesics. Over-the-counter analgesics have been associated with disrupted male endocrinology, while the effects on female endocrinology remain nearly unknown. The aim was to understand the effect of long-term analgesic exposure in females with medication overuse hea

We live in a time where capitalism has long since eliminated any notion of alternative systems from our imaginaries, so that it “occupies the horizon of the thinkable” (Fisher 2009). At the same time, we have seen a (re)turn to positivism and acceptance of the neoliberal system in academia, even in the humanities and studies of art (Grønstad 2020, Poenar 2018). The rejection of the political proje

Context: It is an enigma that agile projects can succeed ‘without requirements’ when weak requirements engineering is a known cause for project failures. While agile development projects often manage well without extensive requirements test cases are commonly viewed as requirements and detailed requirements are documented as test cases.Objective: We have investigated this agile practice of using t

Recently several distinct literatures have thematically converged around the topic of non-European state-making: political scientists – both comparativists and international relations scholars, historical sociologists, comparative and world historians, anthropologists, archaeologists and others, have begun to interest themselves in state making or state formation in non-European settings, and also

This thesis examines the role of beamlines with publication metadata from the European Synchrotron Radiation Facility (ESRF a large scientific facility offering diverse conditions for scientific research. As a user-oriented Big Science facility, the ESRF channels extremely brilliant light into different experimental areas called beamlines that house specific instruments that cater to the needs of

Background: Baleen whales are a clade of gigantic and highly specialized marine mammals. Their genomes have been used to investigate their complex evolutionary history and to decipher the molecular mechanisms that allowed them to reach these dimensions. However, many unanswered questions remain, especially about the early radiation of rorquals and how cancer resistance interplays with their huge n

Background: Access to safe and timely blood transfusion is a cornerstone of modern healthcare but depends on a stable supply of voluntary donations and rigorous hemovigilance systems. O-negative red blood cells are universally compatible and essential for emergency transfusions; however, their scarcity, particularly in low-resource regions, poses significant challenges. To address this challenge,

Abstract in DanishLars-Johan Ekerots bog om svensk som andetsprog foreligger nu i dansk oversættelse og med et noteapparat henvendt til dansksprogede læsere.Bogen har siden udgivelsen i 1995 været et standardværk på læreruddannelser og andre uddannelser i svensk i Sverige og Finland samt på kurser i svensk som fremmedsprog.Bogen har også længe været flittigt brugt af studerende og kommende undervi

Background: Postmastectomy radiotherapy (PMRT) impairs the outcome of immediate breast reconstruction in patients with breast cancer, and the sentinel lymph node (SLN) status is crucial in evaluating the need for PMRT. The aim of this study was to develop and validate models to stratify the risk of clinically significant SLN macrometastases (macro-SLNMs) before surgery. Methods: Women diagnosed wi
