Considerable attention has been paid in recent years to the fundamental changes in the global tourism system related to the emergence of information technologies (IT), and, specifically, the rise of social media. Opportunities to search travel-related information, to reserve and book, evaluate and judge; to receive travel advice and to communicate one's mobility patterns have all profoundly change

The mean time in target range for each centre, cTTR, has previously been shown to correlate to the rate of complications in poorly managed warfarin treatment. However less is known about the correlation when warfarin treatment is well managed.

In vitro mutagen binding ability of human Lactobacillus rhamnosus 231 (Lr 231) was evaluated against acridine orange (AO), N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), 2-amino-3, 8-dimethylimidazo[4,5-f]-quinoxaline (MeIQx) and 4-nitro-o-phenylenediamine (NPD). Binding of AO by Lr 231 is due to adsorption, thereby leading to removal of mutagen in solution and is instantaneous, pH- and concentratio

Tumor cells often evade killing by the complement system by overexpressing membrane-bound complement inhibitors. However, production of soluble complement inhibitors in cells other than hepatocytes was rarely reported. We screened several breast cancer cell lines for expression of soluble complement inhibitor, complement factor I (FI). We also analyzed local production of FI in tissue microarrays

Chondroadherin (CHAD) is a leucine-rich protein promoting cell attachment through binding to integrin alpha(2)beta(1) and syndecans. We observed that CHAD mRNA and protein were lower in bone biopsies of 50-year-old to 65-year-old osteoporotic women and in bone samples of ovariectomized mice versus gender/age-matched controls, suggesting a role in bone metabolism. By the means of an internal cyclic

Neuroblastoma is a highly malignant neoplasm found in young children. Although children with high-risk neuroblastoma respond to chemotherapy, relapses are common. On account of poor treatment outcome, new treatment strategies are constantly sought for neuroblastoma. Polyamine analogues are potentially novel substances for treatment of neuroblastoma. In this study, we have treated two neuroblastoma

Background Patients with severe hemophilia A and factor VIII inhibitors are at increased risk for serious bleeding complications and progression to end-stage joint disease. Effective strategies to prevent bleeding in such patients have not yet been established. Methods We enrolled patients with hemophilia A who were older than 2 years of age, had high-titer inhibitors, and used concentrates known

Preeclampsia remains a major problem worldwide for mothers and babies. Despite intensive study, we have not been able to improve the management or early recognition of preeclampsia. At least part of this is because of failure to standardize the approach to studying this complex syndrome. It is possible that within the syndrome there may be different phenotypes with pathogenic pathways that differ

The European Male Ageing Study (EMAS) was designed to examine the hypothesis that inter-individual and regional variability in symptomatic dysfunctions, alterations in body composition and health outcomes in ageing men can be explained by different rates of decline in anabolic hormones, the most important of which being testosterone. Between 2003 and 2005, 3369 community-dwelling men, aged between

We have studied the homolytic dissociation of a methyl radical from a model of methyl cobalamin. For this reaction, density functional theory with an atom-pairwise dispersion correction (DFT-D) gives a dispersion contribution to the bond dissociation energy (BDE) of 22-51 kJ mol(-1) depending on the functional, i.e. much more than common estimates for the total dispersion interaction energy of the

We have studied the transverse-momentum (p(T)) dependence of the inclusive J/psi production in p-Pb collisions at root s(NN) = 5.02 TeV, in three center-of-mass rapidity (y(cms)) regions, down to zero p(T). Results in the forward and backward rapidity ranges (2.03 < y(cms) < 3.53 and -4.46 < y(cms) < -2.96) are obtained by studying the J/psi decay to mu(+)mu(-), while the mid-rapidity region (-1.3

OBJECTIVE: The aim of this study was to evaluate fetal hemoglobin (HbF) and alpha(1)-microglobulin (A1M) in maternal serum as first-trimester biomarkers for preeclampsia (PE). STUDY DESIGN: The design was a case-control study. We included 96 patients in the first trimester of pregnancy (60 with PE and 36 controls). Venous serum samples were analyzed for HbF and total hemoglobin (Hb) by enzyme-link

To compare causes of death and mortality among subjects with and without mood disorder in the Lundby Cohort and to analyse additional mental disorders as risk factors for mortality in subjects with mood disorders.

The identification of the regions where vector-borne diseases are transmitted is essential to study transmission patterns and to recognize future changes in environmental conditions that may potentially influence the transmission areas. SGS1, one of the lineages of Plasmodium relictum, is known to have active transmission in tropical Africa and temperate regions of Europe. Nuclear sequence data fr

OBJECTIVE: To study the effect of paracetamol (acetaminophen) on maternal and fetal temperatures in labour. STUDY DESIGN: From a cohort of 185 women with continuous maternal axillary and fetal scalp temperature recordings in labour, 18 women treated with 1000mg paracetamol orally for pyrexia and 36 untreated controls matched for parity, cervical dilatation, and epidural analgesia were selected. El

Until recently, only retrospective studies had been published on salvage high-dose melphalan (HDM) with autologous stem cell 'transplantation' (ASCT). In a prospective, nonrandomized phase-2 study, we treated 53 bortezomib-naïve patients with bortezomib-dexamethasone as induction and bortezomib included in the conditioning regimen along with the HDM. Median progression-free survival (PFS), time to

Aims of the present stud were to describe the distribution of corticotropin releasing factor (CRF) immunoreactivity in rat small and large intestines, to quantify the percentage of CRF-immunoreactive (CRF-IR) enteric neurons, to reveal possible CRF immunoreactivity in cultured myenteric neurons from rat ileum and to examine if additions of CRF, urocortin 1 (Ucn1), CRF antagonist or vasoactive inte

Yangia sp. ND199, a moderate halophile isolated from mangrove soil sample in Vietnam, was found to accumulate poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) from unrelated carbon sources in a medium with 4.5 % (w/v) NaCl. Cultivation with glycerol as carbon source and yeast extract as nitrogen source resulted in maximum cell dry weight of 5.7 g/l and PHBV content of 52.8 wt% (containing 2.9 m

Spinal disorders and especially back and neck pain affect more people and have greater impact on work capacity and health-care costs than any other musculoskeletal condition. One of the difficulties in reducing the burden of spinal disorders is the wide and heterogeneous range of specific diseases and non-specific musculoskeletal disorders that can involve the spinal column, most of which manifest

Deoxyribonucleoside kinases (dNKs) phosphorylate deoxyribonucleosides to their corresponding monophosphate compounds. dNks also phosphorylate deoxyribonucleoside analogues that are used in the treatment of cancer or viral infections. The study of the mammalian dNKs has therefore always been of great medical interest. However, during the last 20 years, research on dNKs has gone into non-mammalian o
