Guangdong Province in China runs a risk of gradually increasing pollution of its agricultural land as a consequence of toxic agricultural products. We concentrate here on the situation for cadmium, copper and lead. For these metals we describe the toxicology, the current pollution and its sources, and what can be done to improve the situation by cleaning the soil from pollutants, by choice of crop

In order to compare the two species’ flight performance over the exposed and windy Falsterbo Peninsula, where thermal conditions seldomly are very favorable, we used tracking radar to study flight parameters of sparrowhawks Accipiter nisus and common buzzards Buteo buteo during autumn migration. The results showed a clear difference between sparrowhawks and common buzzards in their flight altitude

Many migratory bird species fly mainly during the night (nocturnal migrants), others during daytime (diurnal migrants) and still others during both night and day. Need to forage during the day, atmospheric structure, predator avoidance and orientation conditions have been proposed as explanations for the widespread occurrence of nocturnal migration. However, the general principles that determine t

Background and purpose - Epidemiological studies of full-thickness rotator cuff tears (FTRCTs) have mainly investigated degenerative lesions. We estimated the population-based incidence of acute FTRCT using a new diagnostic model. Patients and methods - During the period November 2010 through October 2012, we prospectively studied all patients aged 18-75 years with acute onset of pain after should

A 6-cm fresh proximal ileum surgical specimen from a blood group A(1)Le(a-b+) secretor individual was used for stepwise isolation of epithelial cells from villus tip to crypt bottom by gentle washing with ethylenediaminetetraacetic acid-containing buffer. Acid and non-acid sphingolipids were prepared from the epithelial cell fractions and the non-epithelial intestinal residue. Molecular informatio

Introduction. Rituximab has significantly improved the prognosis for patients with both indolent and aggressive non-Hodgkin's lymphoma. An economic evaluation was carried out to assess the cost-effectiveness in Sweden of rituximab as maintenance therapy for patients with follicular lymphoma in remission after second line therapy. Materials and methods. The incremental cost and effectiveness of rit

This work investigates the imaging performance, in terms of contrast and resolution, of two different time-gated ballistic imaging setups commonly used in spray research. It is shown that the two setups generate similar spatial resolution in the presence of scattering media. The simpler (2f) setup, however, is less sensitive to component misalignments and time-gate induced aberrations than the com

Emissions of greenhouse gases in many European countries are declining, and the European Union (EU) believes it is on track in achieving emission reductions as agreed upon in the Kyoto Agreement and the EU's more ambitious post-Kyoto climate policy. However, a number of recent publications indicate that emission reductions may also have been achieved because production has been shifted to other co

We examine the applicability of the extended law of corresponding states (ELCS) to equilibrium and non equilibrium features of the state diagram of the globular protein lysozyme. We provide compelling evidence that the ELCS correctly reproduces the location of the binodal for different ionic strengths, but fails in describing the location of the arrest line. We subsequently use Mode Coupling Theor

Diabetic retinopathy is an ophthalmic complication of diabetes that currently affects 93 million people worldwide. Diabetic macular edema is a subtype of diabetic retinopathy that is characterized by leaking blood vessels in the central part of the retina, and it is a major cause of vision loss in individuals with diabetes. Screening for retinopathy is performed at regular intervals to identify su

Objectives To describe clinical and ultrasound features of Brenner tumors of the ovary. Methods In this retrospective study, the databases of the International Ovarian Tumor Analysis (IOTA) studies and one tertiary center were searched to identify patients who had undergone an ultrasound scan before surgery for an adnexal mass that proved to be a Brenner tumor. Twenty-eight patients with 29 Brenne

Samples of settled dust were collected in 14 animal houses and examined for the presence of bacterial endotoxin with the Limulus (LAL) test and the gas chromatography - tandem mass spectrometry (GC-MSMS) technique, based oil the detection of 3-hydroxy fatty acids (3-OH-FAs) as chemical markers of the endotoxin lipopolysaccharide. The median concentrations of the endotoxin in dust determined with L

Popular Abstract in Swedish Every breath you take – Every move you make Astma och allergier tillhör våra vanligaste folksjukdomar och de har ökat under de senaste fyra decennierna, särskilt bland barn och ungdomar. Under samma period så har inställningen till fysisk aktivitet och olika livsstilsfaktorer i samhället förändrats. Det är allmänt accepterat att fysisk aktivitet är bra for hälsan och viAsthma and allergies are common diseases in adolescents and have increased during the last few decades. All elite level sports activities result in increased risk of asthma and rhinitis regardless of sport practised. Physical activity is at the same time regarded as a health-promoting factor and is recommended both for the prevention and treatment of diseases. The aim of this study was to explore
