Background: In this study, we further developed an artificial intelligence (AI)-based method for the detection and quantification of tumours in the prostate, lymph nodes and bone in prostate-specific membrane antigen (PSMA)-targeting positron emission tomography with computed tomography (PET–CT) images. Methods: A total of 1064 [18F]PSMA-1007 PET–CT scans were used (approximately twice as many com

Purpose of review Myocardial infarction survivors are at a high risk of a recurrent event despite receiving guideline preventive therapy. There is accumulated evidence that persistent atherosclerotic plaque inflammation contributes to this risk. Oxidized low-density lipoprotein (LDL) is widely recognized as a key factor in plaque inflammation and instability; however, no therapies that directly ta

Background During the last decade, evidence has emerged on selective glomerular hypofiltration syndromes (SGHS), defined by selectively reduced filtration of middle-sized molecules irrespective of kidney function and resulting in a low ratio between cystatin C- and creatinine-based estimated glomerular filtration rates (eGFRcys/eGFRcr). We aimed to examine whether SGHS is a hallmark of premature k

EVs increase demand for critical raw materials (CRMs). Many of the CRMs are mined in just a handful of countries, raising security concerns among business and policymakers. Lithium is particularly precarious due to its high geographic supply concentration, high demand growth rate and few near term substitutes. This study conducts a bottom-up assessment of European lithium extraction projects. The

Bone contains diverse structures. In fast-growing large animals, fibrolamellar bone is formed first and is then gradually replaced by remodelled bone with secondary osteons. Using position-resolved X-ray diffraction and X-ray fluorescence as a 2D multimodal microscopy technique, the nature of biomineral nanocrystals is investigated in bovine bone. Systematic spatial variations are found, for examp

This study explores the informal and formal collaboration networks of teachers in the United States and Sweden, focusing on how teachers construct their professional ego networks of trusted individuals for collaboration. Using Ecological Systems Theory (EST) with an emphasis on the microsystem, the research investigates how teacher ego networks are shaped by factors like experience, access to subj

We present a Raman study of axially heterostructured InP/InGaP nanowires (NWs) for tandem solar cells. The study is carried out using both microRaman spectroscopy (µ-Raman), and tip enhanced Raman spectroscopy (TERS). The results obtained by both methods are compared. The results obtained with each one is supported by the simulation of the light/NW interaction using finite element methods. This si

The ecological conditions show synchronous differences between southern and northern Sweden, due to the delayed immigration of flora and fauna in such a long, narrow country. One of the first forest animals to immigrate was the elk. It was also among the first to disappear from southern Sweden. Mattock-heads made from elk antlers have been found in both southern and northern Sweden. In the south,

In Chapter 11, Oksana Mont and Yuliya Voytenko Palgan examine the relationship between the sharing economy and the concept of sufficiency. The chapter highlights how shared access to goods and services can change consumption patterns, maximising resource use and reducing the need for new production. This can decrease resource extraction and reduce greenhouse gas emissions. The authors discuss how

When, how and why does farming become capitalist? This question has long shaped debates in agrarian studies and economic history. Although traditional analyses emphasize market dependency and competitive pressures, this paper argues for a shift in focus towards the diverse strategies of reproduction that farmers have employed in different historical contexts. Rather than searching for common capit

The chapter describes and discusses the Nordic welfare state approach to governance of the arts using data from Sweden. It enquires into how the Swedish system for public governance of the arts works, in particular with focus on answering the question of whether public governance of the arts does secure artistic freedom, and if so how. In other words, is Swedish public governance of the arts a ben

AimPeak oxygen uptake (VO2peak) is closely related to total heart volume (THV) in healthy individuals. This study aimed to investigate 1) the association between VO2peak and THV in subjects with subclinical diastolic dysfunction, athletes, healthy controls, and patients with established heart failure with and without preserved ejection fraction (HFpEF, HFrEF), and 2) whether VO2peak/THV-index can

Background: The global food system is a major contributor to climate change, accounting for about one-third of human-induced greenhouse gas emissions (GHGE). Shifting toward plant-based diets offers potential benefits for both planetary health and chronic disease prevention. However, epidemiological evidence linking dietary GHGE to health outcomes remains limited and inconsistent. Objective: To ex

Introduction: Most neurodegenerative diseases, including Alzheimer's disease (AD) and multiple sclerosis (MS), feature abnormal tau phosphorylation (p-tau) in the brain. Prior immunostaining studies have shown p-tau accumulation in the AD retina, suggesting it may mirror brain tau pathology. Methods: We used mass spectrometry to quantify p-tau peptides in matched retinal and hippocampal samples fr

Tuberculosis (TB) remains a major public health challenge, with financial and health impacts extending beyond treatment. Both the perspective adopted in cost-effectiveness analyses-which critically determines choices such as the inclusion of patient-incurred costs-and the extent to which long-term post-treatment considerations are incorporated have important policy implications. This study examine

BACKGROUND Orthostatic hypotension (OH), defined as a sustained drop in systolic or diastolic blood pressure upon standing, is known to negatively affect survival in the general population. However, its impact on outcomes in patients with advanced coronary artery disease remains unclear. The aim of this study was to assess the prevalence and prognostic value of OH in patients undergoing isolated c

Purpose: Glomerular filtration rate (GFR) is used to evaluate kidney function. Creatinine and cystatin C levels C are the two endogenous substances used to estimate GFR (eGFRCR and eGFRCYS). Agreement between the two is reflected by the eGFRCYS/eGFRCR-ratio, and an eGFRCYS/eGFRCR-ratio <0.70 is strongly associated with mortality and morbidity. An explanation is a selective decrease in the filtrati
