The composition of the egg parasitoid guild of the golden egg bug, Phyllomorpha laciniata, in Spain

The golden egg bug (Phyllomorpha laciniata (Villers)) is a phytophagous insectwith an unusual reproductive system. Females use the bodies of conspecifics,bothmales and females, as oviposition substrates. In addition, a varying fractionof the eggs is laid on the food plant. Egg carrying on conspecifics increases offspring survival. Predators and, especially, hymenopteran parasitoids are the main ca

Complement evasion strategies of pathogens-Acquisition of inhibitors and beyond.

Activation of the complement system and resulting opsonisation with C3b are key events of the innate immune defense against infections. However, a wide variety of bacterial pathogens subvert complement attack by binding host complement inhibitors such as C4b-binding protein, factor H and vitronectin, which results in diminished opsonophagocytosis and killing of bacteria by lysis. Another widely us

Design space exploration and implementation of RVC-CAL applications using the TURNUS framework

While research on the design of heterogeneous concurrent systems has a long and rich history, a unified design methodology and tool support has not emerged so far, and thus the creation of such systems remains a difficult, time-consuming and error-prone process. The absence of principled support for system evaluation and optimization at high abstraction levels makes the quality of the resulting im

On some microlocal properties of the range of a pseudo-differential operator of principal type

The purpose of this thesis is to obtain microlocal analogues of results by L. Hörmander about inclusion relations between the ranges of first order differential operators with smooth coefficients which fail to be locally solvable. Using similar techniques, we shall study the properties of the range of classical pseudo-differential operators of principal type which fail to satisfy condition (ψ).

Lactate concentration in umbilical cord blood is gestational age-dependent: a population-based study of 17 867 newborns.

OBJECTIVE: To study the influence of gestational age on lactate concentration in arterial and venous umbilical cord blood at birth and to define gestational age-specific reference values for lactate in vigorous newborns. DESIGN: Population-based comparative. SETTING: University hospitals. SAMPLE: Vigorous newborns with validated umbilical cord blood samples. MATERIAL AND METHODS: From 2000 to 2004

Extended-spectrum beta-lactamase-producing Escherichia coli in patients with travellers' diarrhoea.

Abstract The identification of patients carrying extended-spectrum beta-lactamase (ESBL)-producing bacteria is important, since these patients are at risk of receiving inappropriate empirical therapy if they become infected. The purpose of this study was to investigate the occurrence of ESBL-producing bacteria in patients with travellers' diarrhoea. Patients with travellers' diarrhoea (N = 242) ha

Designing for Peer Learning : Mathematics, Games and Peer Groups in Leisure-time Centers

Constrained by national tests and the mathematics curriculum, teachers have problems finding time for exploratory and hands-on mathematical activities, especially so in classes with a reduced pace of progression, for example because of a large proportion of second-language learners. Could the leisure-time center, where time is not earmarked, provide such opportunities? The conclusion of this thesi

Trade languages in the world: general overview

In this paper, we discuss common features found in what we term trade languages. Some languages change their grammatical shape dramatically after intense contacts with other languages. Pidgin and creole languages are often discussed in terms of contacts, but trade languages are slightly different from them on the following points: trade languages are normally formed with mutually intelligible lang

Immunizations with IFNgamma secreting tumor cells can eliminate fully established and invasive rat gliomas.

Immunotherapy of malignant primary brain tumors holds the potential to improve the dismal prognosis after current clinical therapy. Although immunotherapy of experimental gliomas has been demonstrated to have the capacity to cure intracerebral tumors no convincing effects of immunotherapy have been shown in clinical trials. One reason for this could be that some of the models used do not display f

Minimizing Contrast Medium Doses to Diagnose Pulmonary Embolism with 80-kVp Multidetector Computed Tomography in Azotemic Patients.

Background: In diagnosing acute pulmonary embolism (PE) in azotemic patients, scintigraphy and magnetic resonance imaging are frequently inconclusive or not available in many hospitals. Computed tomography is readily available, but relatively high doses (30-50 g I) of potentially nephrotoxic iodine contrast media (CM) are used. Purpose: To report on the diagnostic quality and possible contrast-ind

Spontaneous movements: Effect of denervation and relation to the adaptation of nociceptive withdrawal reflexes in the rat.

Spontaneous movements are a ubiquitous phenomenon during development. Recently, we demonstrated that these movements play a key role in the functional adaptation of spinal reflex circuits. Here, we analyse the role of afferent input in the generation of spontaneous movements and characterize the occurrence of different types of spontaneous movements and their relation to the functional adaptation

Expression of GADS enhances FLT3-induced mitogenic signaling.

GADS is a member of a family of SH2 and SH3 domain-containing adaptors that functions in tyrosine kinase-mediated signaling cascades. Its expression is largely restricted to hematopoietic tissues and cell lines. Therefore, GADS is mainly involved in leukocyte-specific protein tyrosine kinase signaling. GADS is known to interact with tyrosine-phosphorylated SHC, BCR-ABL and KIT. The SH2 domain of G
