The present study is aimed at investigating whether eco-tourists are more ecologically oriented than nature tourists and city tourists. In questionnaire surveys, in line with the hypotheses, the ecotourists expressed more general environmental beliefs than the nature tourists, who, in turn, had more pro-environmental beliefs than the city tourists. Similar results were found in the attitudes the t
The influence of different pressures of CO2 and the addition of caprylic acid methyl ester as an entrainer was studied for the extraction process of borage seed. The increase of CO2 pressure from 100 to 350 bar resulted in the increase in extract yield from 0.14 to 24.29% (w/w) while the changes in the extract composition were not so considerable. The highest solubility of pure caprylic acid methy
The retinoblastoma tumor-suppressor gene, RB, has been implicated in tumor suppression, in regulation of the cell cycle, and in mediating cell differentiation. RB is necessary for hematopoiesis in mice, and aberrant RB-expression is associated with the progress and prognosis of leukemia. We have used antisense oligonucleotides, established clones stably expressing an antisense RB construct, and al
Background: Some, but not all, reports suggest that patients with Gaucher disease are at increased risk of developing malignancies, particularly hematopoietic tumors. The aim of this study was to assess the pattern of Gaucher disease and subsequent malignancies among male veterans admitted to US Veterans Affairs hospitals. Methods: Among 832 294 African American and 3 668 983 white male veterans w
X-linked agammaglobulinemia (XLA) is a hereditary defect of B-cell differentiation in man caused by deficiency of Bruton tyrosine kinase (BTK). A three-dimensional model for the BTK kinase domain, based on the core structure of cAMP-dependent protein kinase, was used to interpret the structural basis for disease in eight independent point mutations in patients with XLA. As Arg-525 of BTK has been
The permeability of skin to nanoparticles of titanium dioxide (TiO2) used in sunscreens as a reflector of the UV wavelengths of sunlight, was examined using nuclear microscopy techniques. Special attention was given to the permeation characteristics of these nanoparticles across the outer layers of skin, the stratum corneum, in healthy and psoriatic skin condition. Aspects that may influence the i
Unlike the Quebec classification system, which is based primarily on pathoanatomy, a new Swedish classification system is based on the site of functional impairment and disability. A prospective study was performed on 85 patients with whiplash-associated disorders grade II according to the Quebec classification. The patients were examined 3-36 months following trauma. A team of professionals with
Tropical agroforests are diverse systems where several predator groups shape animal communities and plant-arthropod interactions. Ants, birds and bats in particular can reduce herbivore numbers and thereby increase crop yield. However, the relative importance of these groups, whether they interact, and how this interaction is affected by management and landscape context, is poorly understood. We j
Background and purpose — Early postoperative mortality is relatively high after total hip arthroplasty (THA) that has been performed due to femoral neck fracture. However, this has rarely been investigated after adjustment for medical comorbidity and comparison with the mortality in an age-matched population. We therefore assessed early mortality in hip fracture patients treated with a THA, in the
The case of a female with moderate haemophilia B is reported. She is the only affected member of her family, and factor IX RFLP analysis shows her to have inherited no maternal markers for polymorphisms located in the first intron and 8 Kb 3' of the polyadenylation signal (DdeI and HhaI, respectively). This clearly indicates a deletion involving at least the last 7 exons of the factor IX gene. Her
English oak (Quercus robur) and European beech (Fagus sylvatica) are amongst the most common tree species growing in Europe, influencing the annual biogenic volatile organic compound (BVOC) budget in this region. Studies have shown great variability in the emissions from these tree species, originating from both genetic variability and differences in climatic conditions between study sites. In thi
New Caledonian crows (Corvus moneduloides) rely heavily on a range of tools to extract prey. They manufacture novel tools, save tools for later use, and have morphological features that facilitate tool use. We report six observations, in two individuals, of a novel tool-use mode not previously reported in non-human animals. Insert-and-transport tool use involves inserting a stick into an object an
Purpose: The vast majority of previous studies suggest that there is no relationship between the acceptable noise level (ANL) and pure-tone hearing thresholds reported as the average pure-tone hearing thresholds (pure-tone average). This study aims to explore (a) the relationship between hearing thresholds at individual frequencies and the ANL and (b) a measure of the slope of the audiogram and AN
In the near future, the number of connected mobile devices and data-rates are expected to dramatically increase. Demands exceed the capability of the currently deployed (4G) wireless communication systems. Development of 5G systems is aiming for higher data-rates, better coverage, backward compatibility, and conforming with “green communication” to lower energy consumption. Massive Multiple-Input
BACKGROUND: We sought to identify potential clinical variables associated with outcomes after radium-223 therapy in routine practice. METHODS: Consecutive non-trial mCRPC patients who received ≥1 dose of radium dichloride-223 at four academic and one community urology-specific cancer centers from May 2013 to June 2014 were retrospectively identified. Association of baseline and on-therapy clinical
Aims: Pulmonary hypertension (PH) patients have high mortality due to right ventricular failure. Predictors of poor prognostic outcome are increased right atrial volume (RAV) and elevated mean right atrial pressure (mRAP). Our aim was to determine whether RAV measured with 2D echocardiography (2DE) and 3D echocardiography (3DE) can detect elevated mRAP in patients evaluated for PH. Methods: Of 85
Background: Falls and fear of falling (FOF) are common in persons with late effects of polio, but there is limited knowledge of associated factors. Objective: To determine how knee muscle strength, dynamic balance, and gait performance (adjusted for gender, age, and body mass index) are associated with falls and FOF in persons with late effects of polio. Design: A cross-sectional study. Setting: A
