Purpose: We compared the rates of febrile urinary tract infection, kidney damage and reflux resolution in children with vesicoureteral reflux treated in 3 ways, including antibiotic prophylaxis, endoscopic therapy and surveillance with antibiotics only for symptomatic urinary tract infection. Materials and Methods: Children 1 to younger than 2 years with grade reflux were recruited into this prosp

Temporal coding of spike-times using oscillatory mechanisms allied to spike-time dependent plasticity could represent a powerful mechanism for neuronal communication. However, it is unclear how temporal coding is constructed at the single neuronal level. Here we investigate a novel class of highly regular, metronome-like neurones in the rat brainstem which form a major source of cerebellar afferen

Ordered nanoporous structures are among the most fascinating and industrially important materials currently in use. The archetypal zeolite material has now been joined by an eclectic array of new structures that exhibit porosity over a wide range of length scales and with order/disorder expressed in a multitude of ways. This raises the bar in terms of characterization and extends a real challenge

The Cambrian 'Orsten' fauna comprises exceptionally preserved and phosphatised microscopic arthropods. The external morphology of these fossils is well known, but their internal soft-tissue anatomy has remained virtually unknown. Here, we report the first non-biomineralised tissues from a juvenile polymerid trilobite, represented by digestive structures, glands, and connective strands harboured in

By the end of 2020, all EU member states need to ensure that all newly constructed buildings consume ` nearly zero' energy and that their energy needs are produced locally as much as possible and with renewable sources; a concept called nearly Zero Energy Buildings (ZEB). At the same time, more and more people live in cities, where the access to local renewable energy sources -wind and solar-is li

The effects of color reconnection (CR) at e(+) e(-) colliders are revisited, with focus on recently developed CR models. The new models are compared with the LEP2 measurements for e(+) e(-) -> W+W- -> q(1)(q) over bar (2)q(3)(q) over bar4 and found to lie within their limits. Prospects for constraints from new high- luminosity e(+) e(-) colliders are discussed. The novel arena of CR in Higgs decay

A major barrier for cancer immunotherapy is the presence of suppressive cell populations in patients with cancer, such as myeloid-derived suppressor cells (MDSC) and tumor-associated macrophages (TAM), which contribute to the immunosuppressive microenvironment that promotes tumor growth and metastasis. Tasquinimod is a novel antitumor agent that is currently at an advanced stage of clinical develo

The recent increase in R&D offshoring has raised fears that knowledge and competitiveness in advanced countries may be at risk of 'hollowing out'. At the same time, economic research has stressed that this process is also likely to allow some reverse technology transfer and foster growth at home. This paper addresses this issue by investigating the extent to which R&D offshoring is associa

A search for pair-produced massive coloured scalar particles decaying to a four-jet final state is performed by the ATLAS experiment at the LHC in proton-proton collisions at root s = 7 TeV. The analysed data sample corresponds to an integrated luminosity of 4.6 fb(-1). No deviation from the Standard Model is observed in the invariant mass spectrum of the two-jet pairs. A limit on the scalar gluon

In Meru, Tanzania, technological and institutional change has turned milk into one of the most reliable and important sources of income for smallholder households. Decades of increased population density have caused land scarcity, leading smallholders to intensify their farming methods and land use, including introducing stall-fed exotic breeds of dairy cows. Meanwhile, a growing urban and rural d

Background Sex determination processes vary widely among different vertebrate taxa, but no group offers as much diversity for the study of the evolution of sex determination as teleost fish. However, the knowledge about sex determination gene cascades is scarce in this species-rich group and further difficulties arise when considering hybrid fish taxa, in which mechanisms exhibited by parental spe

To improve the biologic understanding of the Polycystic Ovarian Syndrome (PCOS) condition by examining the circadian variation and relationship between Anti Müllerian Hormone (AMH), gonadotropins and ovarian steroids in PCOS patients compared to normally ovulating and menstruating women. By comparing the pattern of co-variation between AMH and Luteinizing Hormone, two compounds closely linked to h

Photosynthetic organisms need protection against excessive light. By using non-photochemical quenching, where the excess light is converted into heat, the organism can survive at higher light intensities. This process is partly initiated by the formation of zeaxanthin, which is achieved by the de-epoxidation of violaxanthin and antheraxanthin to zeaxanthin. This reaction is catalyzed by violaxanth

BACKGROUND: The aim of this work was to study the influence of steam cooking on pectin methylesterase (PME) and endogenous alpha- and beta-amylase activities in different tissues (cortex and pith) of raw and heat-treated potatoes cv. Agria. Three different cooking temperatures were chosen (55, 70 and 85 degrees C). For each cooking trial, time-temperature profiles were recorded and the degree of c

Objective and methods: Time-use methodologies have been proposed to be established research techniques when exploring aspects of daily occupations. In this study, two graphs illustrating the time arrangement of occupations as they appear in a continuous sequence were used in order to encourage individuals to reflect on their everyday life. The aim was to investigate the usefulness of a time-geogra

Suboptimal listening conditions interfere with listeners' on-line comprehension. A degraded source signal, noise that interferes with sound transmission, and/or listeners' cognitive or linguistic limitations are examples of adverse listening conditions. Few studies have explored the interaction of these factors in pediatric populations. Yet, they represent an increasing challenge in educational se
