Galaxies are complex objects, yet the number of independent parameters to describe them remains unknown. We present here a non-parametric method to estimate the intrinsic dimensionality of large data sets. We apply it to wide-band photometric data drawn from the COSMOS2020 catalogue and a comparable mock catalogue from the HORIZON-AGN simulation. Our galaxy catalogues are limited in signal-to-nois

Soil aggregate stability has been asserted as an indicator of soil quality. Earthworms are essential for the stability of soil aggregates due to their activities, including burrowing and organic matter decomposition. In this study, we focused on how differences in plant litter quality influences earthworm abundance and composition and, subsequently, macroaggregate stability in an agroforestry ecos

DOPA Decarboxylase (DDC) has been proposed as a cerebrospinal fluid (CSF) biomarker with increased concentrations in Lewy body disorders (LBDs) and highest levels in patients receiving dopaminergic treatment. Here we evaluate plasma DDC, measured by proximity extension assay, and the effect of dopaminergic treatment in three independent LBD (with a focus on dementia with Lewy bodies (DLB) and Park

A series of rigid spiro-acetal-containing diol monomers derived from citric acid were synthesized and reacted with five different diisocyanates to form partially biobased thermoplastic polyurethanes (PUs) with different chemical and physical properties. The PUs had a renewable carbon content between 48 and 71%, and all formed transparent and colorless films with glass-transition temperatures betwe

The intersection of Tolkien’s writing and his environmental agenda have long been studied and the Ents are easily identified as one of the envoys of environmental messages in The Lord of the Rings. The Ents are anthropomorphic Hybrids in their function within the narrative, which can lead to a paradox when considering that ecocritical theories rather disapprove of humanising tools to convey ecolog

Objective: To investigate whether tangential versus segmental portomesenteric venous resection (PVR) impacts surgical and oncological outcome in patients undergoing pancreatoduodenectomy for pancreatic cancer with portomesenteric vein (PMV) involvement. Summary Background Data: Current comparative studies on tangential versus segmental PVR as part of pancreatoduodenectomy for pancreatic cancer inc

ER-positive/HER2-negative (ERpHER2n) breast cancer classified as PAM50 HER2-enriched (ERpHER2n-HER2E) represents a small high-risk patient subgroup. In this study, we investigate genomic, transcriptomic, and clinical features of ERpHER2n-HER2E breast tumors using two primary ERpHER2n cohorts comprising a total of 5640 patients. We show that ERpHER2n-HER2E tumors exhibit aggressive clinical feature

Triple-negative breast cancer (TNBC) is a clinically challenging and molecularly heterogenous breast cancer subgroup. Here, we investigate the DNA methylation landscape of TNBC. By analyzing tumor methylome profiles and accounting for the genomic context of CpG methylation, we divide TNBC into two epigenetic subtypes corresponding to a Basal and a non-Basal group, in which characteristic transcrip

X-ray ptychography provides the highest resolution non-destructive imaging at synchrotron radiation facilities, and the efficiency of this method is crucial for coping with limited experimental time. Recent advancements in multi-beam ptychography have enabled larger fields of view, but spatial resolution for large 3D samples remains constrained by their thickness, requiring consideration of multip

Insoluble tau aggregates within neurofibrillary tangles are a defining neuropathological feature of Alzheimer's disease (AD) and closely correlate with clinical symptoms. Although tau pathology can be assessed using tau positron emission tomography, a more accessible biomarker is needed for diagnosis, prognosis and tracking treatment effects. Here we present a new plasma tau species, the endogenou

LTx remains the definitive treatment for end-stage lung disease, but the increasing demand for donor lungs outpaces the available supply. This chapter explores innovative approaches to expand the pool of viable donor lungs and reduce waiting times, which is crucial to lowering mortality rates among patients on transplant lists. Xenotransplantation, which has made its greatest strides using porcine

The field of organ transplantation is experiencing a transformative shift with the rise of Advanced Therapy Medicinal Products (ATMPs), which include gene therapies, somatic cell therapies, and tissue-engineered products. These therapies offer new, potentially curative treatments for longstanding medical challenges, impacting numerous patients. However, their adoption is hindered by complex regula

As advancements in transplantation techniques continue, the challenge remains the limited availability of suitable donor organs. This chapter explores strategies to expand the donor pool and optimise transplant outcomes, which include the use of extended criteria donors, living lobar transplantation, donor-to-recipient graft size matching, and innovations in hypothermic storage and ex vivo lung pe

Dissolved organic carbon (DOC) affects the acidity in soil and lake waters and buffers both against acidification and against recovery from acidification. Current acidification assessments, based on the widely used MAGIC (Model of Acidification of Groundwater In Catchments) model, often assume constant DOC concentrations through time, but observations suggest this assumption may not be warranted.

Objective. To investigate the course of disability related to the upper extremities (UEs) in early rheumatoid arthritis (RA), and to assess correlations between such disability and clinical variables, including grip force. Methods. In an inception cohort of patients with early RA (diagnosed 1995-2005, N = 222, follow-up 10 yrs), disability of the UEs was assessed using a subscore of the Health Ass
