BACKGROUND: The aim of the study was to determine the role of Vascular Endothelial Growth Factor (VEGF) on the microvasculature and on angiogenetic gene expression after partial hepatectomy (PH) in the rat model.METHODS: To determine the effect of exogenous and endogenous VEGF after PH, rats were subjected to 70% PH and treated either with VEGF, anti-VEGF or NaCl. Postoperatively (3-168 h), vessel
BACKGROUND AND AIM: Hepatorenal syndrome (HRS) occurs in about 20 % of patients with liver cirrhosis and ascites and is characterized by intensive renal vasoconstriction, low glomerular filtration rate but preserved tubular function and normal renal histology. The potential of terlipressin and albumin to reverse HRS after a time period of 14 days has already been shown. However, intravenous albumi
The central component of the complement cascade, C3, is involved in various biological functions, including opsonization of foreign bodies, clearance of waste material, activation of immune cells, and triggering of pathways controlling development. Given its broad role in immune responses, particularly in phagocytosis and the clearance of microbes, a deficiency in complement C3 in humans is often
The humoral barrier in transplant biology is the result of preformed donor-specific antibodies (DSAs), directed either against human leukocyte antigens (HLA) or non-HLA antigens such as blood group (ABO) molecules. The term "sensitization" applies to patients carrying these antibodies. Transplantation is widely accepted as a life-saving opportunity for patients with terminal end-organ disease. How
Non-differentiating bacteria adapt to starvation induced growth arrest by a complex turn-on/turn-off pattern of protein synthesis. This response shows distinct similarities with those of spore formation in differentiating organisms. A substantial amount of information on the non-growth biology of non-differentiating bacteria can be derived from studies on Vibrio strains. One important result is th
Virtual reality can be a useful research tool to investigate how people behave in different fire situations. For the results from such experiments to have good validity, i.e., to represent behaviours that can occur in a real environment, the VR environment must be perceived as a good substitute for the real environment. The project focuses on how to achieve such high-quality VR environments. Two d
Background This prospective cohort study aimed to assess whether postoperative radiotherapy could safely be omitted in women aged 65 years and older with low-risk, estrogen receptor-positive T1N0 breast cancer treated with breast-conserving surgery and adjuvant endocrine therapy. Methods Eligible patients were women aged 65 years and older with unifocal, nonlobular, grade 1 or 2, estrogen receptor
A transcriptional reporter fusion has been introduced into the chromosomal ftsZ locus in such a way that all transcription that normally reaches ftsZ can be monitored. The new Φ(ftsZ-lacZ) fusion yields four times more β-galactosidase activity than a ddlB-ftsQAZ-lacZ fusion on a lambda prophage vector. A strongly polar ddlB::Ω insertion prevents contributions from signals upstream of the ftsQAZ pr
Inherited retinal diseases (IRDs) are a genetically heterogeneous group of Mendelian disorders that often lead to progressive vision loss and involve approximately 300 distinct genes. Although variants in these loci account for the majority of molecular diagnoses, other genes associated with IRD await molecular identification. In this study, we uncover bi-allelic assortments of 23 different (22 lo
The rarity of preserved soft tissues in the fossil record has limited our understanding of the life appearance of extinct vertebrates. However, through examination of various osteological features and comparisons with extant ecomorphological analogues, we can predict some of the external characteristics of ancient taxa. Specifically, for the Cretaceous mosasaurians (a group of seagoing squamates),
Importance: Depressive symptoms are associated with cognitive decline in older individuals. Uncertainty about underlying mechanisms hampers diagnostic and therapeutic efforts. This large-scale study aimed to elucidate the association between depressive symptoms and amyloid pathology. Objective: To examine the association between depressive symptoms and amyloid pathology and its dependency on age,
The medieval church and cemetery of Westerhus (Västerhus) is situated on the island of Frösön in the province of Jämtland, Mid-Sweden. The site was completely excavated and underwent anthropological analysis, published by Nils-Gustaf Gejvall in 1960. A number of early radiocarbon datings were later obtained (Gejvall 1968). In 2009 a new study of the church, site, burials and humans was presented b
Transcriptome-wide association studies (TWAS) are powerful tools for identifying gene-level associations by integrating genome-wide association studies and gene expression data. However, most TWAS methods focus on linear associations between genes and traits, ignoring the complex nonlinear relationships that may be present in biological systems. To address this limitation, we propose a novel frame
Eosinophils are increasingly recognized as adaptable immune cells that exhibit diverse phenotypes and effector functions across different tissues and disease states. While they can induce pathology through degranulation and cytotoxic mediator release, eosinophils also fulfill regulatory and tissue repair roles. Advances in single-cell and spatial technologies have begun to reveal how microenvironm
Summary: The relationship between rheumatoid arthritis (RA) and fracture risk was estimated in an international meta-analysis of individual-level data from 29 prospective cohorts. RA was associated with an increased fracture risk in men and women, and these data will be used to update FRAX®. Introduction: RA is a well-documented risk factor for subsequent fracture that is incorporated into the FRA
Context. Wind dynamics play a pivotal role in governing transport processes within planetary atmospheres, influencing atmospheric chemistry, cloud formation, and the overall energy budget. Understanding the strength and patterns of winds is crucial for comprehensive insights into the physics of ultra-hot-Jupiter atmospheres. Current research has proposed different mechanisms that limit wind speeds
Background Human papillomavirus (HPV) is associated with an increased risk for a variety of squamous cell carcinomas in the general population. The risk for subsequent squamous cell carcinomas in blood or marrow transplantation survivors that are potentially related to HPV (cervical, oropharyngeal, vulvar, vaginal, anal, and penile cancer; HPV-related squamous cell carcinomas) remains unknown. Met
Background: Left-sided pancreatic cancer is associated with worse overall survival (OS) compared with right-sided pancreatic cancer. Although neoadjuvant therapy is currently seen as not effective in patients with resectable pancreatic cancer (RPC), current randomized trials included mostly patients with right-sided RPC. The purpose of this study was to assess the association between neoadjuvant t
