Functional test measures as risk indicators for low back pain among fixed-wing military pilots.
2015
Purpose The purpose of this study was to find out the risk value of functional fitness test (FFT) results for low back pain (LBP) among fixed-wing military pilots. Methods A total of 104 male military pilots were recruited for this study. The study was conducted with a self-administered questionnaire and FFT. The functional tests were performed in the beginning of study (baseline). The questionnaire was carried out at the baseline and 5 years later. Results The isometric low back endurance test result was associated with physical activity-related LBP experienced 5 years later. Demographic information was not associated with LBP. The prevalence of overall LBP was 71% and the flight-related L…
Research Article <i>CD40</i> rs4810485 <i>T>G</i> polymorphism and susceptibility to ankylosing spondylitis in the Latvian…
2018
Ankylosing spondylitis (AS) is a potentially disabling form of a systemic chronic inflammatory arthritis affecting mainly the axial skeleton, with or without extraspinal manifestations. The genetic basis of AS is partly known. Moreover, many autoimmunityrelated genes have pleiotropic effects. Multiple functional polymorphisms in the genes encoding the tumor necrosis factor (TNF) superfamily of cytokines, their receptors, and signaling proteins, are associated with susceptibility to autoimmune diseases. These arguments prompted us to conduct a study evaluating a possible association of single nucleotide polymorphism (SNP) rs4810485 of the CD40 gene, found previously to be involved in other i…
Giant cell arteritis (Horton's disease) in very elderly patients aged 80 years and older: A study of 25 cases
2015
Aim Analysis of the characteristics of very elderly patients with giant cell arteritis (GCA). Methods Patients aged 80 years and older diagnosed with GCA in our department between 1 January 2002 and 31 July 2008 were retrospectively included. For each patient, we recorded general characteristics, reason(s) for hospitalization, specialty of the physician or department that referred the patient to us, medical history, treatment at admission, GCA clinical features, time to diagnosis of GCA, biological screening and GCA treatment. Results We analyzed 25 clinical records, 18 women and seven men with a mean age of 83.9 years. General weakness, visual loss and inflammatory syndrome were the princi…
Real-life practice: rapid improvement in itch symptomatology in patients with atopic dermatitis treated with dupilumab

Sir,Atopic dermatitis is a chronic relapsing inflammatory skin disorder that affects up to 20% of children and 2–5% of the adult population (1). The disease is characterized by erythematous, xeroti...
Challenges and opportunities regarding the use of alternative protein sources: Aquaculture and insects
2019
The world population is constantly growing so that the needs of food, including protein sources, will also increase considerably in the coming years. Animal farming has been related to numerous environmental consequences such as soil erosion, exaggerated water consumption, generation of large quantities of waste and accumulation of greenhouse gases. This is a situation that demonstrates the suitability and importance of finding more sustainable protein alternatives without losing the quality and the nutritional benefits of current common protein sources. In this context, it is worth highlighting the potential of insects and products derived from aquaculture. Particularly, farmed aquatic foo…
The effect of peracetic acid on microbial community, water quality, nitrification and rainbow trout (Oncorhynchus mykiss) performance in recirculatin…
2020
Abstract Microbial biofilters control water quality and enable the overall function of recirculation aquaculture systems (RAS). Changes in environmental conditions can affect the abundance and interactions of the diverse microbial populations of the biofilter, affecting nitrification of harmful ammonium and thus fish health. Here, we examined the effect of different application frequencies (0, 1, 2 and 4 times per week) of a common disinfectant, peracetic acid (PAA, applied 1.1 mg l−1 twice per day), on biofilter microbial communities, focusing especially on nitrifying microbial groups and using a high throughput sequencing of 16S rRNA gene and quantitative PCR (qPCR). In addition, we measu…
Leisure-time physical activity and artery lumen diameters: A monozygotic co-twin control study
2010
Exercise is thought to increase the diameter of the conduit arteries supplying the muscles involved. We studied the effects of a physically active vs inactive lifestyle on artery diameters in monozygotic (MZ) twin pairs discordant over 30 years for leisure-time physical activity habits. In a population-based co-twin control study design, six middle-aged (50-65 years) same-sex MZ twin pairs with long-term discordance for physical activity were comprehensively identified from the Finnish Twin Cohort (TWINACTIVE study). Discordance was initially defined in 1975 and the same co-twin remained significantly more active during the 32-year follow-up. The main outcomes were arterial lumen diameters …
Effects of Food Label Health and Nutrition Claims on Consumer Perceptions
2009
Two experiments are reported that examined consumers' perceptions of food package labels where health and nutrition claims were present and where they had been removed. Unlike previous studies examining the influence of information on perception, realistic materials were used. This was accomplished by presenting information on a computer as photo-realistic images of packages where claims had been removed by editing to give a without-claims condition. Automatic presentation of materials and data collection meant participants proceeded through the computer questionnaire without the presence of an experimenter. The experiment was conducted with both British and French consumers. No significant…
Kinship, acquired and inherited status, and population structure at the Early Bronze Age Mokrin necropolis in northern Serbia
2020
AbstractTwenty-four ancient genomes with an average sequencing coverage of 0.85±0.25 X were produced from the Mokrin necropolis, an Early Bronze Age (2,100-1,800 BC) Maros culture site in Serbia, to provide unambiguous identification of biological sex, population structure, and genetic kinship between individuals. Of the 24 investigated individuals, 15 were involved in kinship relationships of varying degrees, including 3 parent-offspring relationships. All observed parent-offspring pairs were mother and son. In addition to the absence of biological daughters, we observed a number of young women and girls with no biological relatives in our sample. These observations, together with the high…
Alternative NF-κB signaling regulates mTEC differentiation from podoplanin-expressing precursors in the cortico-medullary junction
2015
The thymic epithelium forms specialized niches to enable thymocyte differentiation. While the common epithelial progenitor of medullary and cortical thymic epithelial cells (mTECs and cTECs) is well defined, early stages of mTEC lineage specification have remained elusive. Here, we utilized in vivo targeting of mTECs to resolve their differentiation pathways and to determine whether mTEC progenitors participate in thymocyte education. We found that mTECs descend from a lineage committed, podoplanin (PDPN)-expressing progenitor located at the cortico-medullary junction. PDPN(+) junctional TECs (jTECs) represent a distinct TEC population that builds the thymic medulla, but only partially supp…
