China’s influence in extractive industry sectors worldwide has expanded in tandem with the rising global demand for the natural resources integral to producing such low carbon products as electric vehicles. Many Chinese-operated mining projects overseas have hence generated broad concern on the ground about their negative environmental and social impacts. Chinese actors, meanwhile, have begun to e

Background: MRI is an important tool in the prostate cancer work-up, with special emphasis on the ADC sequence. This study aimed to investigate the correlation between ADC and ADC ratio compared to tumor aggressiveness determined by a histopathological examination after radical prostatectomy.Methods: Ninety-eight patients with prostate cancer underwent MRI at five different hospitals prior to radi

The COVID-19 pandemic, the surge of populism, the climate crisis and many other destabilizing factors in our time, all point at the expectation of trustworthy knowledge and reliable organization devoted to knowledge production and dissemination. However, universities remain enmeshed in economic liberalization and ensuing cultural struggles where their funding, governance and practices reflect mark

For many years, universities represented the ultimate outpost for professional autonomy in Western democracies. Despite little insight into the professional practices of scholars or administrators, governments provided the academic profession with extensive discretion, including the freedom to regulate qualifications for positions, terms for promotion, quality standards, goals, performance indicat

Background Celiac disease has an increasing incidence worldwide and is treated with lifelong adherence to a gluten-free diet. We aimed to describe gluten-free diet adherence rates in children with screening-identified celiac disease, determine adherence-related factors, and compare adherence to food records in a multinational prospective birth cohort study. Methods Children in The Environmental De

Background Intravesical recurrence (IVR) after surgery for upper tract urothelial carcinoma (UTUC) is a clinical problem. We investigated if preoperative invasive diagnostic modalities (IDM) such as antegrade/retrograde uretero-pyelography and/or selective urine cytology/barbotage, and URS with or without concomitant biopsy are associated with IVR after radical surgery for UTUC. Risk of death from

While mechanics was developed under the idea of reciprocal action (interactions), electromagnetism, as we know it today, takes a form more akin to unilateral action. Interactions call for spatial relations, unilateral action calls for space, just one reference centre. In contrast, interactions are matters of relations that require at least two centres. The development of the relational electromagn

Semiquantitative PET measures such as SUV ratio (SUVr) have several advantages over quantitative measures, such as practical applicability and relative computational simplicity. However, SUVr may potentially be affected by changes in blood flow, whereas quantitative measures such as nondisplaceable binding potential (BPND) are not. For 18F-flortaucipir PET, the sensitivity of SUVr for changes in b

Group A streptococcus (GAS) is a highly adapted, human-specific pathogen that is known to manipulate the immune system through various mechanisms. GAS’ M protein constitutes a primary target of the immune system due to its spatial configuration and dominance on the bacterial surface. Antibody responses targeting the M protein have been shown to favor the conserved C region. Such antibodies (Abs) c

During the last decades, more and more devices have been connected to the Internet.Today, there are more devices connected to the Internet than humans.An increasingly more common type of devices are cyber-physical devices.A device that interacts with its environment is called a cyber-physical device.Sensors that measure their environment and actuators that alter the physical environment are both c

Background: Repolarization prolongation can be the earliest electrophysiological change in ischemia, but its role in arrhythmogenesis is unclear. The aim of the present study was to evaluate the early ischemic action potential duration (APD) prolongation concerning its causes, expression in ECG and association with early ischemic ventricular fibrillation (phase 1A VF). Methods: Coronary occlusion

Neuroblastoma is a childhood cancer derived from the sympathetic nervous system. High-risk neuroblastoma patients have a poor overall survival and account for ~15% of childhood cancer deaths. There is thus a need for clinically relevant and authentic models of neuroblastoma that closely resemble the human disease to further interrogate underlying mechanisms and to develop novel therapeutic strateg

Trots att ytan av formellt skyddade områden ökar så minskar den biologiska mångfalden i Sverige. För att naturvården i Sverige ska bli effektivare krävs det ökad kunskap om varför områdesskyddet inte räcker till för att bevara den biologiska mångfalden. En effektiv naturvård kräver kunskap om vilken effekt områdesskydd har på den biologiska mångfalden. Eftersom biologisk mångfald påverkas av ekolo
