The properties of the arterial vasculature depend to a large extent on the activities of smooth muscle cells, which, in turn, are determined by their extracellular environment. During pathological conditions, such as atherosclerosis, this interaction is altered. In close proximity to medial smooth muscle cells are basement membrane components, such as different isoforms of laminin. These proteins
Objectives: Irreversible electroporation (IRE) is a new modality for tumor ablation. Electrodes are placed around the tumor, and a pulsed, direct current with a field strength of 2000 V/cm is delivered. The direct current drives cells into apoptosis and cell death without causing significant heating of the tissues, which spares the extracellular matrix and proteins. The purpose of this review was
Osteoinduction can be enhanced by combining scaffolds with bone morphogenic protein-2 (BMP-2). However, BMP's are known to also cause bone resorption. This can be controlled using bisphosphonates like zoledronic acid (ZA). In this study, we produced two different scaffolds containing silk-fibroin, chitosan, agarose and hydroxyapatite (HA) with and without bioactive glass. The aims of the study wer
The etiology of human leukocyte antigen (HLA)-associated organ-specific autoimmune diseases is incomplete. In type 1 diabetes and celiac disease, the strongest associations are with the HLA-DR3-DQ2 and DR4-DQ8 haplotypes, whereas the DQB1*06:02 allele has a strong negative association. In contrast, narcolepsy, especially as recently triggered by the Pandemrix® H1N1 vaccine (GlaxoKlineSmith (GSK),
Natural habitats are rapidly declining due to urbanisation, with a concomitant decline in biodiversity in highly urbanised areas. Yet thousands of different species have colonised urban environments. These organisms are exposed to novel urban conditions, which are sometimes beneficial, but most often challenging, such as increased ambient temperature, chemicals, noise and light pollution, dietary
Insulin-dependent diabetes mellitus (IDDM) is associated with autoreactivity against GAD but the diagnostic sensitivity (positivity in disease) and specificity (negativity in health) of isoform-specific GAD antibodies have yet to be defined in assay systems suitable for screening large number of samples. One set of IDDM patient (n=10) and control (n=50) standard sera were used to develop quantitat
The loss of p53 induces spontaneous tumors in mice, and p53 mutations are found in approximately 50% of human tumors. These tumors are generally caused by a number of events, including genomic instability, checkpoint defects, mitotic defects, deregulation of transcriptional targets, impaired apoptosis, and G 1 deregulation or a combination of these effects. In order to determine the role of protei
A growing body of research highlights the importance of cognition for prediction of falls in Parkinson's disease (PD). However, a previously proposed prediction model for future near falls and falls in PD, which includes history of near falls, tandem gait, and retropulsion, was developed without considering cognitive impairment. Therefore, by using a sample of 64 individuals with relatively mild P
Background: Parents with small children constitute a vulnerable group as they have an increased risk of sick leave due to stress-related disorders compared to adults without children. It has been shown that mothers and fathers to small children together spend more time in paid work than any other group, which could create negative stress and an experience of low occupational balance. Aim: The aim
Penetration of the viral genome into a host cell nucleus is critical for initiation of viral replication for most DNA viruses and a few RNA viruses. For herpesviruses, viral DNA ejection into a nucleus occurs when the capsid docks at the nuclear pore complex (NPC) basket with the correct orientation of the unique capsid portal vertex. It has been shown that capsid vertex-specific component (CVSC)
Chronic obstructive pulmonary disease (COPD) is characterized by airway inflammation, small airway remodeling, and emphysema. Airway remodeling in patients with COPD involves both the airway epithelium and the subepithelial extracellular matrix (ECM). However, it is currently unknown how epithelial remodeling in COPD airways depends on the relative influence from inherent defects in the epithelial
Most patients with anti-glomerular basement membrane (anti-GBM) disease present with rapidly progressive glomerulonephritis with or without pulmonary haemorrhage; however, there are several variants and vigilance is necessary to make a correct diagnosis. Such variants include overlap with anti-neutrophil cytoplasm antibodies-associated vasculitis and membranous nephropathy as well as anti-GBM occu
Human use of natural resources poses a great challenge to social-ecological and socio-technical sys- tems alike: supply risks, pollutant and greenhouse gas emissions, waste generation on the one hand, but also issues of global justice and societal well-being on the other hand. In order to test potential im- pacts of developments and strategies relevant to resource policy, the SimRess project first
Existing event detection algorithms for eye-movement data almost exclusively rely on thresholding one or more hand-crafted signal features, each computed from the stream of raw gaze data. Moreover, this thresholding is largely left for the end user. Here we present and develop gazeNet, a new framework for creating event detectors that do not require hand-crafted signal features or signal threshold
Eradicating poverty and achieving food and nutrition security in a sustainable environment is difficult to achieve without adequate access to affordable cooking fuel. It is therefore important to understand the common sources of cooking energy used by people in rural areas and the challenges faced in making fuel sources economically viable, socially acceptable and ecologically sustainable. In the
We investigated the accuracy of a linear soft tissue artefact (STA) model in human movement analysis. Simultaneously recorded bone-mounted pin and skin marker data for the thigh and shank during walking, cutting and hopping were used to measure and model the motion of the skin marker clusters within anatomical reference frames (ARFs). This linear model allows skin marker movements relative to the
Klebsiella pneumoniae and Pseudomonas aeruginosa are two leading causes of burn and wound infections, pneumonia, urinary tract infections, and more severe invasive diseases, which are often multidrug resistant (MDR) or extensively drug resistant. Due to this, it is critical to discover alternative antimicrobials, such as bacteriophage lysins, against these pathogens. Unfortunately, most lysins tha
Efficiently finding covariate model structures that minimize the need for random effects to describe pharmacological data is challenging. The standard approach focuses on identification of relevant covariates, and present methodology lacks tools for automatic identification of covariate model structures. Although neural networks could potentially be used to approximate covariate-parameter relation
Purpose: This study examined if speed reduction effects from animal-vehicle collision (AVC) countermeasures are merely local or do extend to a wider area, and what implications the results have on road planning practice regarding AVCs. Methods: Twenty-five drivers drove repeatedly on a 9-km long road stretch in a high-fidelity driving simulator. The development of vehicle speed in the surrounding
Pro-inflammatory and amyloidogenic S100A9 protein is an important contributor to Alzheimer’s disease (AD) pathology. Traumatic brain injury (TBI) is viewed as a precursor state for AD. Here we have shown that S100A9-driven amyloid-neuroinflammatory cascade was initiated in TBI and may serve as a mechanistic link between TBI and AD. By analyzing the TBI and AD human brain tissues, we demonstrated t
