Genomic characterization of the HER2-enriched intrinsic molecular subtype in primary ER-positive HER2-negative breast cancer

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

The DNA methylation landscape of primary triple-negative breast cancer

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

Multi-beam multi-slice X-ray ptychography

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

Plasma MTBR-tau243 biomarker identifies tau tangle pathology in Alzheimer's disease

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

New frontiers in lung transplantation : a bioengineering perspective

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

ESOT Roadmap for Advanced Therapy Medicinal Products in Transplantation : Navigating Regulatory Challenges to Enhance Access and Care

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

Methods and practices to increase the donor pool in adult lung transplantation

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

The Impact of Variable DOC Concentrations on Acidification Assessments

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.

Disability Related to the Upper Extremities in Early Rheumatoid Arthritis—Long-Term Course and Disease Variable Impact : A Cohort Study

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

High prevalence of undocumented SARS-CoV-2 infections revealed by analysis of nucleocapsid-specific IgG responses in diagnosed and undiagnosed individuals

Acute SARS-CoV-2 infections are not always diagnosed; hence an unknown proportion of all infections are not documented. SARS-CoV-2 can induce spike and nucleocapsid protein specific IgG antibodies, which can be detected in seroprevalence studies to identify a previous infection. However, with the introduction of vaccines containing the spike protein it is no longer possible to use spike-IgG as a m

Enhanced small intestinal organoid-derived epithelial cell adhesion and growth in organ-on-a-chip devices

Organ-on-a-chip devices are predominately made of the polymer polymethylsiloxane (PDMS), exhibiting several attractive properties e.g., transparency, gas permeability, and biocompatibility. However, the attachment of cells to this polymer has proven challenging, especially for delicate primary cells e.g., small intestinal organoid-derived epithelial cells. Hence, a need to functionalize and coat t

demo film for Impossible Colors (score follower video)

Impossible colors is not a hypothesis, but rather more hyperbole. In this musical piece "impossible colors" refer to illusions of timbre in sound, not vision.Impossible colors are colors that we do not normally see; that some fictional colors are beyond the functional perceptual space of humans. Some theories looking at forbidden colors, borrowed from color research in vision are applied in this p

Jarash in the Islamic Ages (c. 700–1200 CE) : a critical review

To Alan Walmsley, at sixty-fiveJarash (also Jerash, Greek Gerasa) ranks among the principal urban centres of Late Antique and Early Islamic Jordan. Despite being one of the most intensively investigated urban sites within the region, the history of Jarash during the Islamic ages, in particular after the massive earthquake of 749, remains a topic of profound disagreement. Drawing on previously unpu

Quality of Life, Anxiety and Depressive Symptoms in North Sea–Progressive Myoclonus Epilepsy : A Comparative Analysis With Other Hyperkinetic Movement Disorders

Objectives: North Sea–Progressive Myoclonus Epilepsy (NS-PME) is a rare, childhood-onset disorder primarily characterized by movement disorders including progressive myoclonus and ataxia; subsequently accompanied by varying degrees of epilepsy. While motor symptoms are clearly defined, quality of life (QoL) has never been investigated in NS-PME. Additionally, nonmotor symptoms (NMS) including anxi
