Mutations in the NRF2-KEAP1 pathway are common in non-small cell lung cancer (NSCLC) and confer broad-spectrum therapeutic resistance, leading to poor outcomes. The cystine/glutamate antiporter, system xc-, is one of the >200 cytoprotective proteins controlled by NRF2, which can be non-invasively imaged by (S)-4-(3-18F-fluoropropyl)-l-glutamate ([18F]FSPG) positron emission tomography (PET). Throu

In this study, we assess the impact of an image restoration pipeline, designed for digital mammography, on the detectability of microcalcifications of different sizes across varied radiation exposures. The restoration pipeline first removes the noise of the image considering a Poisson-Gaussian noise model that incorporates quantum and electronic noise. Then, it appropriately merges the noisy and d

Axonal injuries commonly contribute to poor functional outcomes following traumatic brain injury (TBI). To assess cerebral blood flow (CBF) and energy metabolic disturbances in a TBI model of widespread axonal injury, we exposed 105 adult mice to the central (midline) fluid percussion injury (cFPI) diffuse TBI model, or sham injury, and used 9.4 T magnetic resonance (MR) arterial spin labeling (AS

Background: Out of hospital cardiac arrest (OHCA) is a significant public health problem associated with high mortality and high healthcare costs. The Targeted Therapeutic Mild Hypercapnia after Resuscitated Cardiac Arrest (TAME) randomised clinical trial showed that targeted mild hypercapnia did not lead to better neurologic outcomes at 6 months compared to normocapnia after OHCA. We aimed to est

Introduction: Cranioplasty, a surgical procedure to restore skull integrity and aesthetic contour following decompressive craniectomy, poses challenges in material selection and timing, driven by the lack of guidelines and ongoing regulatory changes. Research question: This study aimed to provide an overview of current cranioplasty practices in Europe, explicitly addressing a potential shift towar

BACKGROUND: Head impacts are common in contact sports such as boxing and occur at times of elevated core body and brain temperatures induced by the exercise. Following impact, elevated brain temperature may lead to the development of exacerbated brain injury that can be monitored by blood biomarkers. Blood-brain biomarkers S100B and glial fibrillary acidic protein (GFAP) reflect glial injury; neur

Denna avhandling breddar rådande förståelser av stipendier och deras systematiska användning inom internationell högre utbildning genom att introducera en ny uppsättning teoretiska verktyg för att undersöka sådana satsningar. Med fokus på organisationer i Mexiko och Indonesien samt de studenter de sponsrade till svenska masterprogram mellan 2013 och 2020, utforskar studien värderingsprocesser, samThis thesis broadens prevailing understandings of scholarships and their systematic use in international higher education, introducing a novel set of theoretical tools for examining such endeavors. Focusing on organizations in Mexico and Indonesia and the students they sponsored in Swedish master’s degree programs between 2013-20, the study explores valuation processes, coordination puzzles and et

Background: All available recommendations about the management of antithrombotic therapies (ATs) in patients who experienced traumatic brain injury (TBI) are mainly based on expert opinion because of the lack of strength in the available evidence-based medicine. Currently, the withdrawal and the resumption of AT in these patients is empirical, widely variable, and based on the individual assessmen

The thermal sensitivity of early life stages can play a fundamental role in constraining species distributions. For egg-laying ectotherms, cool temperatures often extend development time and exacerbate developmental energy cost. Despite these costs, egg laying is still observed at high latitudes and altitudes. How embryos overcome the developmental constraints posed by cool climates is crucial kno

The aim of these guidelines is to provide evidence‑based guidance for temperature control in adults who are comatose after resuscitation from either in-hospital or out-of-hospital cardiac arrest, regardless of the underlying cardiac rhythm. These guidelines replace the recommendations on temperature management after cardiac arrest included in the 2021 post-resuscitation care guidelines co-issued b

We have developed a method for simultaneous tomosynthesis and mechanical imaging, called DBTMI. Mechanical imaging measures the stress distribution over the compressed breast surface. Malignant tissue is usually stiffer than benign, which results in higher stress on the compressed breast and enables to distinguish malignant from benign findings. By combining tomosynthesis and mechanical imaging, w

Tumor growth rate estimations can provide useful information about tumor progression and aggressiveness. Understanding the breast cancer progression and aggressiveness could aid with personalized screening/follow-up, treatment options, and prognosis. This paper reports a preliminary estimation of the tumor volume doubling time (TVDT) for cancers detected during the Malmö Breast Tomosynthesis Scree

Objects created by 3D printers are increasingly used in various medical applications. Today, affordable 3D printers, using Fused Deposition Modeling are widely available. In this project, a commercially available 3D printer was used to replicate a conventional radiographic contrast detail phantom. Printing materials were selected by comparing their x-ray attenuation properties. Two replicas were p

Purpose: To compare the performance of targeted temperature management (TTM) at 33 °C using intravascular (IC) vs. surface-cooling (SFC) devices after out-of-hospital cardiac arrest (OHCA). Methods: A post hoc analysis including OHCA patients randomized to hypothermia in the TTM2-trial (NCT02908308) comparing hypothermia with normothermia. The main outcome was cooling performance, defined as the p

Background and Objectives: This project explored the needs of art galleries and collectors for Digital Asset Management Systems (DAMS), in order to fill an existing knowledge gap and help companies to analyse these needs. Bespoken difficulties in the field significantly challenge the development of DAMS and have thus also hampered the evolvement of high-quality systems for the art market. There se

Historiskt sett har människor gjort invändningar grundade på tankefrihet, samvetsfrihet och religionsfrihet i förhållande till obligatorisk värnpliktstjänstgöring. Denna samvetsvägran inom militären är en erkänd rätt i nationella, regionala och internationella människorättsinstrument. I den Europeiska konventionen om skydd för de mänskliga rättigheterna och de grundläggande friheterna är denna rätHistorically, objections based on the freedom of thought, conscience and religion have been invoked in relation to compulsory military service. These conscientious objections are protected by national, regional and international human rights instruments. In the European Convention on Human Rights this right is grounded in Article 9 on the freedom of thought, conscience and religion. In Europe, the

The central theme of this thesis is anthropogenic climate change; governments' inability to create an effective, inclusive response mechanism that manages to mitigate anthropogenic emissions; and advocates efforts to coerce States to act by invoking State responsibility in adjudicatory dispute settlement processes. States' failure to act in accordance with scientific risk assessments and

Background T-cell activation and clonal expansion are essential to effective immunotherapy responses in non-small cell lung cancer (NSCLC). The distribution of T-cell clones may offer insights into immunogenic mechanisms and imply potential prognostic and predictive information. Methods We analyzed α/β T-cell receptor (TCR) clonality using RNA-sequencing of bulk frozen tumor tissue from 182 patien
