<i>Background</i> - Liver sinusoidal endothelial cells (LSECs) and Kupffer cells (KCs; liver resident macrophages) form the body’s most effective scavenger cell system for the removal of harmful blood-borne substances, ranging from modified self-proteins to pathogens and xenobiotics. Controversies in the literature regarding the LSEC phenotype pose a challenge when determining distinct functionalities ...

<i>Background</i> - Recurrent aphthous stomatitis (RAS) is the most common form of oral ulcerative disease, whose cause is still unknown. Researchers have found the association of many factors with the occurrence of RAS, and proposed oral bacterial infection could be a cause for this disease.<p> <p><i>Methods</i> - To investigate whether the occurrence of RAS is associated with oral bacterial ...

<i>Background</i> - The majority of oral cavity cancers arise in the oral tongue. The aim of this study was to evaluate the prognostic value of tumor budding in oral tongue squamous cell carcinoma, both as a separate variable and in combination with depth of invasion. We also assessed the prognostic impact of the 8th edition of the American Joint Committee on Cancer’s TNM classification (TNM8), where ...

<p><i>Purpose:</i> The goal was to investigate potential roles played by vitamin D in the regulation of joint cartilage biology. We studied the expression of two central elements of vitamin D metabolism, namely the vitamin D receptor and its converting enzyme 1­α­hydroxylase in human knee cartilage and chondrocytes. <p><i>Methods and Materials:</i> Expression of receptor and enzyme was determined ...

The γ-aminobutyric acid (GABA) type B receptor (GABA<sub>B</sub-R) belongs to class C of the G-protein coupled receptors (GPCRs). Together with the GABA_A receptor, the receptor mediates the neurotransmission of GABA, the main inhibitory neurotransmitter in the central nervous system (CNS). In recent decades, the receptor has been extensively studied with the intention being to understand ...

Increased knowledge about the role of horizontal gene transfer is key to improve our understanding of the spread of antimicrobial resistance (AMR) in human populations. We therefore studied the dissemination of the <i>bla</i>_CTX-M-15 extended-spectrum-β-lactamase (ESBL) gene in <i>Klebsiella pneumoniae</i> isolates obtained from stool samples from hospitalized children and healthy controls ...

The Norwegian Scientific Committee for Food Safety (VKM) has appointed an ad hoc-group of experts to answer a request from the Norwegian Food Safety Authority regarding benefit and risk assessment of B. lactis Bb12 in baby foods focusing on the age groups 4-6 months, 6-12 months and 1-3 years. This assessment is based on the literature provided by the notifier as well as that found by a MEDLINE search.

VKM ga i 2006 to risikovurderinger vedrørende introduksjon av høypatogent aviært influensavirus til Norge. Den foreliggende vurderingen er en oppdatering av disse vurderingene og besvarer spørsmål om risiko i ulike situasjoner i Norge våren 2007.

S. diarizonae er et subspecies av Salmonella som påvises endemisk hos sau i enkelte regioner i Norge. Det er derfor stilt spørsmål om mikrobens potensielle og reelle betydning for både folke- og dyrehelsen. Det er også stilt spørsmål ved påstanden om at Norge har en tilnærmet salmonella-fri husdyrpopulasjon kan forsvares når S. diarizonae påvises relativt ofte hos sau i Norge i dag. Mattilsynet har ...

<p><i>Background - </i>Telementored ultrasound (US) connects experts to novices through various types of communication and network technologies with the overall aim to bridge the medical imaging gap between patients’ diagnostic needs and on-site user experience. The recurrent theme in previous research on remote telementored US is the limited access to US machines and experienced users. This study ...
