Arable weeds in organically managed fields may foster arthropod generalist predators by the provision of shelter and favorable microclimate (structure-mediated effects) and the provision of additional animal and floral food resources (resource-mediated effects). In three organically managed winter wheat fields in Central Germany, we investigated the impact of weed removal and introduction of artif
The role of peripheral arterial disease in ulcerated diabetic feet has long been underestimated. Progressive claudication, rest pain and the extent of irreversible tissue loss have frequently been indications for revascularization for neuroischaemic ulcers in diabetic patients. These typical ischaemic symptoms are warning signs that are less frequent in diabetic individuals with ischaemia than tho
The authors report on the fabrication of subsurfaced 100-600 nm wide nanochannels in fused silica with top slit openings in the size range of 5-10 nm. Such nanochannels can be used in combination with a nanofluidics system to guide molecular motors and quickly switch the chemical environment inside the nanochannels through diffusion via the top slits. To realize nanochannel top slits in this size
We use three different polymer solvent mixture models to theoretically determine the existence of capillary-induced phase separation in simple pores under supercritical bulk conditions. These models undergo bulk demixing, due to quite different mechanisms, yet readily display supercritical transitions without the use of esoteric interactions in the capillary. The theoretical method used to analyze
Three experiments were conducted to study on a more fine-grained level how processing a picture facilitates learning from text. In Experiment 1 (N = 85), results from a drawing task revealed that the global spatial structure of a pulley system picture was extracted even from its brief inspection (for 600 ms, 2 s). In Experiment 2 (N = 105), students who initially inspected the pulley system pictur
BACKGROUND: Open abdomen (OA) therapy frequently results in a giant planned ventral hernia. Vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) enables delayed primary fascial closure in most patients, even after prolonged OA treatment. Our aim was to study the incidence of hernia and abdominal wall discomfort 1 year after abdominal closure. METHODS: A prospective multicenter
Aims: Multiple lines of evidence have implicated beta-amyloid (A beta) in the pathogenesis of Alzheimer's disease (AD). However, the mechanism(s) whereby A beta is involved in the disease process remains unclear. The dominant hypothesis in AD has been that A beta initiates the disease via toxicity from secreted, extracellular A beta aggregates. More recently, an alternative hypothesis has emerged
Objective: Childhood cancer survivors are commonly treated with GH for GH deficiency that develops either as a result of primary malignancy or its treatment. One study - the Childhood Cancer Survivor Study (CCSS) demonstrated increased risk of second neoplasm (SN) in GH-treated childhood cancer survivors compared with non-GH treated, after adjusting for key risk factors. We assessed the incidence
This work presents a new mathematical formulation of biologically effective dose (BED) for radiation therapy where effects of repair need to be considered. The formulation is based on the observation that the effects of repair, both during protracted irradiation and of incomplete repair between fractions, can be written using a convolution, i.e. [Formula: see text] where T is the total irradiation
In 2010, the Swedish Stroke Register (Riksstroke; RS) established a module for transient ischemic attacks (RS-TIA). We report a diagnostic validation study of patients included in RS-TIA.
In the period 2009–2011, Member States discussed whether the EU should increase its emissions reduction target for 2020 beyond the existing 20%. This discussion has not resulted in any agreement, the different actors being deeply divided between those calling for a step-up to a higher target (for instance 30%) and those opposed to any kind of increase. The division can be seen as a result of a con
Glomus tumours are rare in adults, and such tumours may be associated with neurofibromatosis-1 (Nf-1). Here we describe successful treatment of two glomus tumours initially in the long finger and, one year later, in the thumb in a 17-year young girl with Nf-1.
Postprandial glucose, together with related hyperinsulinemia and lipidaemia, has been implicated in the development of chronic metabolic diseases like obesity, type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). In this review, available evidence is discussed on postprandial glucose in relation to body weight control, the development of oxidative stress, T2DM, and CVD and in maintain
Objectives We sought to replicate the association between the kinesin-like protein 6 (KIF6) Trp719Arg polymorphism (rs20455), and clinical coronary artery disease (CAD). Background Recent prospective studies suggest that carriers of the 719Arg allele in KIF6 are at increased risk of clinical CAD compared with noncarriers. Methods The KIF6 Trp719Arg polymorphism (rs20455) was genotyped in 19 case-c
Impaired interatrial conduction or interatrial block is well documented but is not described as an individual electrocardiographic (ECG) pattern in most of ECG books, although the term atrial abnormalities to encompass both concepts, left atrial enlargement (LAE) and interatrial block, has been coined. In fact, LAE and interatrial block are often associated, similarly to what happens with ventricu
Intradialytic hypotension (IDH) is the most common adverse complication during hemodialysis. Its early prediction and prevention will dramatically improve the quality of life for patients with an end stage renal disease. In a recent study, changes in the normalized envelope of the test statistic of the photoplethysmograpic (PPG) signal were found to predict acute symptomatic IDH. In the present st
Objective. Uterine sarcomas (US) are rare malignancies with unclear aetiology. Studies on uterine sarcomas in the setting of second primary malignant tumours can provide clues to aetiology and identify side effects of different treatments. Methods. A cohort of 8606 cases of US was extracted from the data from 13 cancer registries and followed for second primary cancers within the period 1943-2000.
