An overview of optical techniques for environmental monitoring is presented. Range-resolved measurements of atmospheric pollutants can be performed using the differential absorption lidar technique. Fluorescence lidar allows assessment of vegetation status and also the conditions of the facades of historical buildings. Diode lasers provide particularly realistic schemes for atmospheric gas analysi
Research on HIV vaccines, as well as studies on HIV pathogenesis in human and SIV in the macaque model, require the availability of simple and standardized assays for quantification of neutralizing antibodies to primary virus isolates. We have recently developed and standardized assays using human cell lines engineered to express CD4 and co-receptors for HIV and SIV entry. One cell line originated
Escherichia coli K1 and Group B Streptococcus (GBS) are the most common bacteria that cause meningitis during the neonatal period. Complement, the first line of defence in the host, acts on these bacteria to opsonize with various components of complement for subsequent presentation to phagocytes. To counteract these opsonization effects, E. coli and GBS bind to the complement regulators C4 binding
We very briefly discuss proposed in the literature possible scenarios for intermediate mass black holes formation in globular clusters. We also discuss the results of the MOCCA simulations of about 2000 models (BigSurvey) regarding the distribution of events connected with electromagnetic and gravitational radiations, namely: mass transfer on IMBH, collisions and mergers with IMBH and mergers with
Human exposures to metals and metalloids such as arsenic frequently occur as mixtures, and hence it is important to consider interactions among these elements in terms of both mechanisms of action and for risk assessment purposes. Interactions among these elements may produce additive, synergistic/potentiative, or antagonistic effects that may be manifested as direct cellular toxicity (necrosis or
Data on longitudinal lung function change in the elderly are scarce. Uncertainty remains about whether to use absolute or relative change and how it relates to subject demographics.We studied absolute and relative forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) change in a population-based geriatric sample using a repeated measurements model adjusted for age, sex, smoking ha
Pathogens that invade the human host are confronted by a multitude of defence mechanisms aimed at preventing colonization, dissemination and proliferation. The most frequent outcome of this interaction is microbial elimination, in which the complement system plays a major role. Complement, an essential feature of the innate immune machinery, rapidly identifies and marks pathogens for efficient rem
Introduction To assess differences in initial symptoms, treatments, and bowel function between children with Hirschsprung's disease (HD) with or without a cognitive dysfunction (CD). Materials and Methods The study included children with HD who underwent transanal endorectal pull-through. A retrospective chart review was performed to collect data on patient characteristics, diagnosis, and treatm
Incubation experiments are the most common approach to measure methane (CH 4 ) oxidation potential in soils from various ecosystems and land-use practices. However, the commonly used headspace CH 4 injection into microcosms and the shaking of the soil slurry duri
Traditionally tourists are treated as passive media consumers but this chapter departs from a performance perspective emphasizing tourists’ active role. This chapter deals with how popular music affects tourists’ experiences in destinations by exploring the performance of place-making practices by tourists as they engage with music. The performance perspective is complemented with a ritual perspec
Many retail chains believe that the personal service encounter is the solution to declining sales figures. Via a large-scale study of Swedish fashion consumers, we demonstrate, that this may not necessarily be the case. We argue that retailers can potentially save money and convert more customers by providing a more automated journey, which includes self-service technologies, for some customers, a
Introduction: Under-dosing is a recognized problem with current nicotine replacement therapy (NRT). Therefore, a new 6mg nicotine gum has been developed. To compare the nicotine uptake from the 6mg gum versus currently available NRT products, two pharmacokinetic studies were performed.Methods: In one randomized crossover study, 44 healthy adult smokers received single doses of 6, 4, and 2mg nicoti
About 8000 Swedish women are diagnosed with breast cancer each year, and around 1500 die from the disease. Triple-negative breast cancer (TNBC) constitutes 7-14% of all breast cancer and is characterized by an aggressive phenotype with poor prognosis and no targeted therapy available. The aim of this thesis was to evaluate new potential prognostic biomarkers in breast cancer, and with special focu
Aluminium-based adjuvants (ABAs) have been used in human and veterinary vaccines for decades, and for a long time, the adjuvant properties were believed to be mediated by an antigen depot at the injection site, prolonging antigen exposure to the immune system. The depot hypothesis is today more or less abandoned, and instead replaced by the assumption that ABAs induce an inflammation at the inject
Despite the fact that the origin of human immunodeficiency virus (HIV) being a contamination and a mutation originating from primates is well-documented alternative narratives are often being heard ofespecially in sub-Saharan Africa. One such narrative is about HIV being man-made in a military laboratory in the United States. In this article, it is shown how this narrative was fabricated by the in
Antibody microarray based technology is a powerful emerging tool in proteomics, target discovery, and differential analysis. Here, we report the first study where recombinant antibody fragments have been used to construct large scale antibody microarrays, composed of 127 different antibodies against mostly immunoregulatory antigens. The arrays were based on single framework recombinant antibody fr
In order to evaluate three common human papillomavirus (HPV) DNA tests for key performance indices in population-based cervical screening, we sampled 12,527 women aged 3238 years who attended invitational, population-based screening and followed them for 4 years with comprehensive registry linkages. Three different HPV DNA tests (GP5+/6+general primer PCR (using either AmpliTaq or AmpliTaq Gold DN
To test whether the arrangement of fibre types in the human muscle (m. vastus lateralis) from clinically healthy and young males can be regarded as random, fascicles at different parts of the muscle and with different fibre type proportions were studied. The randomness of the arrangement of fibre types was assessed by the number of enclosed fibres in a fascicle and, on the basis of a model, tested
