Background: Accurate and internationally comparable human papillomavirus (HPV) DNA detection and typing services are essential for HPV vaccine research and surveillance. Objectives: This study assessed the proficiency of different HPV typing services offered routinely in laboratories worldwide. Study design: The HPV Laboratory Network (LabNet) has designed international proficiency panels that can
The Late Ordovician mass extinction (LOME) coincided with dramatic climate changes, but there are numerous ways in which these changes could have driven marine extinctions. We use a palaeobiogeographic database of rhynchonelliform brachiopods to examine the selectivity of Late Ordovician-Early Silurian genus extinctions and evaluate which extinction drivers are best supported by the data. The firs
Thymic stromal lymphopoietin (TSLP) is a pleiotropic cytokine, hitherto mostly known to be involved in inflammatory responses and immunoregulation. The human tslp gene gives rise to two transcription and translation variants: a long form (lfTSLP) that is induced by inflammation, and a short, constitutively-expressed form (sfTSLP), that appears to be downregulated by inflammation. The TSLP forms ca
This paper studies the consequences on high temperature corrosion when biomass is co-fired with coal in oxy-fuel combustion, a concept that would enable negative CO2 emissions by combining renewable fuels with CO2 capture. The particular focus of the work is the sulphation of alkali chlorides which is studied by means of experiments and modelling. The melting point of alkali sulphates is higher th
An assay has been established for quantitative evaluation of lentivirus coreceptor use with the help of GHOST(3) cells. GHOST(3) cells were derived from the human osteosarcoma cell line, HOS, and have been engineered to stably express CD4 and one or another of the chemokine receptors CCR3, CCR5, CXCR4, CXCR6/STRL33/Bonzo, or the orphan receptor GPR15/BOB. The indicator cell line carries the HIV-2
The Sanfilippo syndrome type B is a lysosomal storage disorder caused by deficiency of alpha-N-acetylglucosaminidase; it is characterized by profound mental deterioration in childhood and death in the second decade. For understanding the molecular genetics of the disease and for future development of DNA-based therapy, we have cloned the cDNA and gene encoding alpha-N-acetylglucosaminidase. Clonin
A multiwell tissue culture system was developed to study the influence of various substances on hepatitis A virus (HAV) propagation. A panel of 20 substances of different structure types, each with known effect against at least some viruses, was studied at a concentration of 100 microM. Three substances showed reproducible inhibition. The strongest inhibitor, arabinosylcytosine, also produced cyto
Antibodies provide some protection against cytomegalovirus-mediated disease. All aspects of antibody recognition of important viral antigens are however not fully appreciated. Glycoprotein B (gB), a key protein in the viral membrane, participates in viral infection and it is a component of prototype vaccines. By using combinatorial antibody library and selection technology, novel antibody specific
Large international biobank studies can make substantial contributions to scientific research by validation of the biological importance of previous research and by identification of previously unknown causes of disease. However, regulations for patient consent that are too strict and discrepancies in national policies on informed consent might hinder progress. Therefore, establishment of common g
Numerous studies have reported a positive association between ambient fine particles and daily mortality, but little is known about the particle properties or environmental factors that may contribute to these effects. This study assessed potential modification of radon on PM2.5 (particulate matter with an aerodynamic diameter <2.5 ?m)-associated daily mortality in 108 U.S. cities using a two-stag
COVID-19 represents a risk to people's life and societies in their current shapes and functions, with institutionalised responses redefining everyday life. Crises in society can induce fear and tensions that can unite and divide people, inducing acts of solidarity and polarisation. The study explored articulations of solidarity and polarisation in relation to the COVID-19 pandemic and related risk
BACKGROUND: Environmental contamination of norovirus (NoV) is believed to be a significant source for further transmission in hospitals.AIM: To investigate the risk of acquiring NoV in a cleaned room previously occupied by a patient with NoV infection. The risk of having a roommate with recent NoV infection was also assessed.METHODS: In a retrospective cohort, comprising 33,788 room stays at five
Importance: Although tramadol is increasingly used to manage chronic noncancer pain, few safety studies have compared it with other opioids. Objective: To assess the associations of tramadol, compared with codeine, with mortality and other adverse clinical outcomes as used in outpatient settings. Design, Setting, and Participants: Retrospective, population-based, propensity score-matched cohort st
During severe inflammatory and infectious diseases, various mediators modulate the equilibrium of vascular tone, inflammation, coagulation and thrombosis. This Review describes the interactive roles of the renin–angiotensin system, the complement system, and the closely linked kallikrein–kinin and contact systems in cell biological functions such as vascular tone and leakage, inflammation, chemota
Eunuchs and members of the transgender community are yet to be recognized as an effective human resource and this diversity in the workforce is still invisible. A tiny portion of the transgender community is employed, and they are tagged as purple collar employees. It is generally claimed that coworkers do not accept members of the transgender community in the workplace and are not willing to work
This chapter presents two case analyses, one situated in Sweden and the other in Poland, where attempts have been made to intervene in the existing laws regulating access to abortion. The first case involves the lawsuits filed by midwives in Sweden who claimed to have been discriminated against on the grounds of their religion when they had been turned down for work due to their objection to perfo
Building information modeling (BIM) and building energy modeling (BEM) are two key tools to make the transition to net-zero energy buildings (NZEB). However, a recent literature review indicated that the conversion from BIM to BEM is currently dysfunctional, due to limitations regarding competencies, processes, and technology. In this article, a case study is presented to show how the information
This research explores teacher educators' self-reported preparedness to teach students with special educational needs. Teacher educators are concerned with preparing the next generation of teachers who will, in turn, be addressing the needs of students with special educational needs within schools. Being able to address this important task also in their own teaching at the teacher education progra
Between 15 and 27kyrb2k (thousands of years before 2000CE) during the last glacial, Greenland experienced a prolonged cold stadial phase, interrupted by two short-lived warm interstadials. Greenland ice-core calcium data show two periods, preceding the interstadials, of anomalously high atmospheric dust loading, the origin of which is not well understood. At approximately the same time as the Gree
