Kidney Segmentation in Renal Magnetic Resonance Imaging - Current Status and Prospects
(Journal article; Peer reviewed, 2021)Magnetic resonance imaging has achieved an increasingly important role in the clinical work-up of renal diseases such chronic kidney disease (CKD). A large panel of parameters have been proposed to diagnose CKD among them ... -
Kinetic and oligomeric study of Leishmania braziliensis nicotinate/ nicotinamide mononucleotide adenylyltransferase
(Journal article; Peer reviewed, 2020)Nicotinamide adenine dinucleotide (NAD) is an essential coenzyme involved in REDOX reactions and oxidative stress defense systems. Furthermore, NAD is used as substrate by proteins that regulate essential cellular functions ... -
Labor epidural analgesia and subsequent risk of offspring autism spectrum disorder and attention-deficit/hyperactivity disorder: A cross-national cohort study of over 4.5 million individuals and their siblings in Finland, Norway, and Sweden
(Journal article; Peer reviewed, 2023)Background A recent study has suggested that labor epidural analgesia may be associated with increased rates of offspring autism spectrum disorder. Subsequent replication attempts have lacked sufficient power to confidently ... -
Lack of collagen XVIII leads to lipodystrophy and perturbs hepatic glucose and lipid homeostasis
(Journal article; Peer reviewed, 2020)Liver and adipose tissues play important roles in the regulation of systemic glucose and lipid metabolism. Extracellular matrix synthesis and remodelling are significantly altered in these tissues in obesity and type 2 ... -
Lack of functional normalisation of tumour vessels following anti-angiogenic therapy in glioblastoma
(Peer reviewed; Journal article, 2017)Neo-angiogenesis represents an important factor for the delivery of oxygen and nutrients to a growing tumour, and is considered to be one of the main pathodiagnostic features of glioblastomas (GBM). Anti-angiogenic therapy ... -
Lactate dehydrogenases promote glioblastoma growth and invasion via a metabolic symbiosis
(Journal article; Peer reviewed, 2022)Lactate is a central metabolite in brain physiology but also contributes to tumor development. Glioblastoma (GB) is the most common and malignant primary brain tumor in adults, recognized by angiogenic and invasive growth, ... -
The laminin response in inflammatory bowel disease: Protection or malignancy?
(Peer reviewed; Journal article, 2014-10-27)Laminins (LM), basement membrane molecules and mediators of epithelial-stromal communication, are crucial in tissue homeostasis. Inflammatory Bowel Diseases (IBD) are multifactorial pathologies where the microenvironment ... -
Leukocyte transmigration into tissue-engineered constructs is influenced by endothelial cells through Toll-like receptor signaling
(Peer reviewed; Journal article, 2014-12-20)Introduction Inflammation plays a crucial role in tissue regeneration, wound healing, and the success of tissue-engineered constructs. The aim of this study was to investigate the influence of human umbilical vein endothelial ... -
The life cycle and enigmatic egress of coronaviruses
(Journal article; Peer reviewed, 2022)There has been considerable recent interest in the life cycle of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), the causative agent of the Covid-19 pandemic. Practically every step in CoV replication—from ... -
Linking metabolism and histone acetylation dynamics by integrated metabolic flux analysis of Acetyl-CoA and histone acetylation sites
(Journal article; Peer reviewed, 2024)Objectives Histone acetylation is an important epigenetic modification that regulates various biological processes and cell homeostasis. Acetyl-CoA, a hub molecule of metabolism, is the substrate for histone acetylation, ... -
Linking resting state metabolite concentrations in the dorsal anterior cingulate cortex to response inhibition in OCD, a combined fMRI-MRS study
(Journal article; Peer reviewed, 2023)Introduction Obsessive-compulsive disorder (OCD) has been associated with abnormal brain activation in regions related to response inhibition, such as the dorsal anterior cingulate cortex (dACC), as well as dysregulation ... -
Lipopolysaccharide induces filtrate leakage from renal tubular lumina into the interstitial space via a proximal tubular Toll-like receptor 4–dependent pathway and limits sensitivity to fluid therapy in mice
(Journal article; Peer reviewed, 2019-12-16)Sustained oliguria during fluid resuscitation represents a perplexing problem in patients undergoing therapy for septic acute kidney injury. Here, we tested whether lipopolysaccharide induces filtrate leakage from the ... -
LncRNAs Predicted to Interfere With the Gene Regulation Activity of miR-637 and miR-196a-5p in GBM
(Journal article; Peer reviewed, 2020)Rigorous molecular characterization of biological systems has uncovered a variety of gene variations underlying normal and disease states and a remarkable complexity in the forms of RNA transcripts that exist. A recent ... -
Long-term consumption of an obesogenic high fat diet prior to ischemia-reperfusion mediates cardioprotection via Epac1-dependent signaling
(Peer reviewed; Journal article, 2016-11-28)Background: Obesity is still considered a risk factor for cardiovascular disease, although more recent knowledge also suggests obesity to be associated with reduced morbidity and mortality - the “obesity paradox”. This ... -
Long-term treatment with valganciclovir improves lentiviral suicide gene therapy of glioblastoma
(Peer reviewed; Journal article, 2019)Background: Suicide gene therapy for malignant gliomas has shown encouraging results in the latest clinical trials. However, prodrug application was most often restricted to short-term treatment (14 days), especially when ... -
Loss of COPZ1 induces NCOA4 mediated autophagy and ferroptosis in glioblastoma cell lines
(Journal article; Peer reviewed, 2021)Dysregulated iron metabolism is a hallmark of many cancers, including glioblastoma (GBM). However, its role in tumor progression remains unclear. Herein, we identified coatomer protein complex subunit zeta 1 (COPZ1) as a ... -
Loss of N-terminal acetyltransferase A activity induces thermally unstable ribosomal proteins and increases their turnover in Saccharomyces cerevisiae
(Journal article; Peer reviewed, 2023)Protein N-terminal (Nt) acetylation is one of the most abundant modifications in eukaryotes, covering ~50-80 % of the proteome, depending on species. Cells with defective Nt-acetylation display a wide array of phenotypes ... -
