Objective. To study the clinical recovery from acute otitis media ( AOM) in children, 2-16 years of age, managed with or without treatment with phenoxymethylpenicillin ( PcV). Design. An open, prospective randomized trial. Children aged between 2 and 16 years, presenting with one- or double-sided AOM ( without perforation) with symptom duration of less than four days, were included. The children w

Background: While plasma-derived concentrates containing large amounts of von Willebrand factor (VWF) are effective in treating von Willebrand disease (VWD), optimal dosing remains to be fully characterized. Objectives: To determine the feasibility of dosing Haemate P-(R) VWF/factor VIII (FVIII) concentrate based on pharmacokinetics (PK) in the management of surgical subjects with VWD. Methods: VW

Background: In a public health perspective, it is of interest to assess the magnitude of geographical variations in ischaemic heart disease (IHD) mortality and quantify the strength of contextual effects on IHD. Objective: To investigate whether area effects vary according to the individual and contextual characteristics of the population, socioeconomic contextual influences were assessed in diffe

Acoustic actuation can be used to perform several tasks in microfluidic systems. In this paper, we investigate an acoustic separator through micro-PIV analysis in stop-flow mode and numerical simulations, and a good agreement between the two is found. Moreover, we demonstrate that it is not sufficient only to characterize devices in flow-through mode, since in these systems much different resonant

The two most frequently examined biomarkers in the diagnosis of dementia are cerebrospinal fluid (CSF) tau and beta-amyloid(1-42) (Abeta(1-42)). An assay for tau phosphorylated at threonine 181 (phospho-tau) has recently been developed. We studied these three markers in patients with possible Alzheimer's disease (AD; n = 23), probable AD (n = 50), AD with relevant cerebrovascular disease (AD with

We discuss how techniques from multiresolution analysis and phase space transforms can be exploited in solving a general class of evolution equations with limited smoothness. We have wave propagation in media of limited smoothness in mind. The frame that appears naturally in this context belongs to the family of frames of curvelets. The construction considered here implies a full-wave description

From clinical studies it is known that recurrent depressive episodes associate with a reduced hippocampal volume. Conversely, preclinical studies have shown that chronic antidepressant treatment increases hippocampal neurogenesis. Consequently, it has been suggested that a deficit in hippocampal neurogenesis is implicated in the pathophysiology of depression. To study a potential correlation betwe

The microfungal communities of a mire in northern Sweden were studied. Three plant communities were sampled at two depths, one dry ombrotrophic, one wet ombrotrophic, and one wet minerotrophic site. The fungi were isolated on malt agar using the dilution-plate technique. The most commonly isolated species were Chaunopychnis alba, Mortierella isabellina, Mortierella pulchella, Mycelium radicis atro

We examine the evolutionary stability of year-round residency in territorial populations, where breeding sites are a limiting resource. The model links individual life histories to the population-wide competition for territories and includes spatial variation in habitat quality as well as a potential parent-offspring conflict over territory ownership. The general form of the model makes it applica

BACKGROUND: Early age at first full-term pregnancy and increasing parity are associated with a reduced risk of breast cancer. However, whether pregnancy decreases the risk of early-onset hereditary breast cancer is unknown. There is concern that pregnancy may increase breast-cancer risk in carriers of BRCA1 and BRCA2 germline mutations. We aimed to establish whether pregnancy is a risk factor for

The filamentous fungus Penicillium cyclopium conidiates in the presence of calcium ions in submerged culture without nutrient limitation according to a precisely timed program. Conidiation could be prematurely induced in a nutritionally sufficient medium which had previously supported growth, suggesting that a metabolite which influenced the process was produced. A diterpenoid with conidiation-ind

In acidic soils, monomeric aluminium (Al3+) can reach levels that are toxic to plants, thus preventing many species from growing there. Organic acids chelate Al and render it non-toxic. It has been shown that exudation of organic acids by Al-tolerant crops increases their tolerance to Al. We have extended this observation to wild plants by comparing the ability of ten herbs to exude organic acids

Objective: GH causes insulin resistance, impairs glycemic control and increases the risk of vascular diabetic complications. Sulphonylureas stimulate GH secretion and this study was undertaken to investigate the possible stimulatory effect of repaglinide and nateglinide, two novel oral glucose regulators, on critical steps of the stimulus-secretion coupling in single rat somatotrophs. Methods: Pat

Wind direction conditions during the 20th century in Scania, southern Sweden, are investigated using an estimated series of monthly wind vector components (east-west u component and north-south v component). The series is developed from a regression relationship between pairwise (1973 to 1997) monthly averages of 10-m surface wind from Scania and a monthly geostrophic wind, based on mean sea level

Abstract in UndeterminedIt has recently been argued that giving is spontaneous while greed is calculated (Rand et al. 2012). If greed is calculated we would expect that cognitive load, which is assumed to reduce the influence of cognitive processes, should affect greed. In this paper we study both charitable giving and the behavior of dictators under high and low cognitive load, to test if greed i

Abstract in UndeterminedThe recent MPEG Reconfigurable Media Coding (RMC) standard aims at defining media processing specifications (e.g. video codecs) in a form that abstracts from the implementation platform, but at the same time is an appropriate starting point for implementation on specific targets. To this end, the RMC framework has standardized both an asynchronous dataflow model of computat

Consider a parametrized family of general hidden Markov models, where both the observed and unobserved components take values in a complete separable metric space. We prove that the maximum likelihood estimator (MLE) of the parameter is strongly consistent under a rather minimal set of assumptions. As special cases of our main result, we obtain consistency in a large class of nonlinear state space
