Early terminal complement blockade and C6 deficiency are protective in enterohemorrhagic Escherichia coli-infected mice

Complement activation occurs during enterohemorrhagic Escherichia coli (EHEC) infection and may exacerbate renal manifestations. In this study, we show glomerular C5b-9 deposits in the renal biopsy of a child with EHEC-associated hemolytic uremic syndrome. The role of the terminal complement complex, and its blockade as a therapeutic modality, was investigated in a mouse model of E. coli O157:H7 i

Nonmedical use of prescription drugs in the European Union

Background: Nonmedical prescription drug use (NMPDU) refers to the self-treatment of a medical condition using medication without a prescriber's authorization as well as use to achieve euphoric states. This article reports data from a cross-national investigation of NMPDU in five European Countries, with the aim to understand the prevalence and characteristics of those engaging in NMPDU across the

Nondestructive Complete Mechanical Characterization of Zinc Blende and Wurtzite GaAs Nanowires Using Time-Resolved Pump− Probe Spectroscopy

We have developed and demonstrated an experimental method, based on the picosecond acoustics technique, to perform nondestructive complete mechanical characterization of nanowires, that is, the determination of the complete elasticity tensor. By means of femtosecond pump−probe spectroscopy, coherent acoustic phonons were generated in an ensemble of nanowires and their dynamics was resolved. Specif

Cost minimization of network services with buffer and end-to-end deadline constraints

Cloud computing technology provides the means to share physical resources among multiple users and data center tenants by exposing them as virtual resources. There is a strong industrial drive to use similar technology and concepts to provide timing sensitive services. One such is virtual networking services, so called services chains, which consist of several interconnected virtual network functi

On understanding of external and internal integration in supply chains : Challenges and evaluation

Benefits of implementing Supply Chain Integration (SCI) are acknowledged in existing integration literature. Integration extending beyond functional silos and firm boundaries is expected to provide value for customers in terms of higher quality, improved service level, and reduced costs. In addition, internal integration allows business functions to align around a single company goal. This type of

Differentiation in putative male sex pheromone components across and within populations of the African butterfly Bicyclus anynana as a potential driver of reproductive isolation

Sexual traits are often the most divergent characters among closely related species, suggesting an important role of sexual traits in speciation. However, to prove this, we need to show that sexual trait differences accumulate before or during the speciation process, rather than being a consequence of it. Here, we contrast patterns of divergence among putative male sex pheromone (pMSP) composi

MHC-I provides both quantitative resistance and susceptibility to blood parasites in blue tits in the wild

Major histocompatibility complex (MHC) genes are central for the adaptive immune response against parasites. Here, we investigated potential associations among MHC-I alleles and blood parasite infections in a natural breeding population of a passerine bird, the blue tit Cyanistes caeruleus, in central Spain. We screened both infection status (presence/absence of infection) and infection intensity

Composition and structure of high temperature dairy fouling

The fouling structure and composition is dependent on the product, but also on the heating process applied to it. The structure will have profound effect on the cleaning process and the down time in the production plant. Here, the structure of high temperature (137 °C) milk fouling has been investigated, which so far has not been sufficiently studied in a systematic way. This particular fouling ha

Palaeozoic 'conodont pearls' and other phosphatic micro-spherules

Sub-millimetre-sized phosphatic spherules are often found in acetic acid-insoluble residues produced for microfossil extraction. As they are typically associated with conodont elements and have a similar chemical composition, they are informally known as 'conodont pearls'. Still, the origin of these micro-spherules has been controversial, and authors have disagreed regarding their mode of formatio

Living the neurochemical self? : Experiences after the success of the SSRIs

This is an exploration, in dialogue with Nikolas Rose’sconceptualization of the neurochemical self, of how people takingantidepressants through in-depth interviews make sense of theirexperiences of using selective serotonin reuptake inhibitors. Theneurochemical self, according to Rose, is a self understood asregulated by neurochemical processes, where how we feel ismapped onto the body, more preciThis is an exploration, in dialogue with Nikolas Rose’s conceptualization of the neurochemical self, of how people taking antidepressants through in-depth interviews make sense of their experiences of using selective serotonin reuptake inhibitors.

Acute lymphoblastic leukemia

Acute lymphoblastic leukemia (ALL) is classified as B-lineage ALL (B-ALL) and T-lineage ALL (T-ALL). The incidence of ALL is almost three times higher in white than black children. Among adults, ALL is more frequent in younger patients, with a median age of less than 30 years. The morphology-immunology-cytogenetics (MIC) subgroups are associated with nonrandom karyotypic abnormalities in a manner

Timesat for processing time-series data from satellite sensors for land surface monitoring

The TIMESAT software package has been developed to enable monitoring of dynamic land surface processes using remotely sensed data. The monitoring capability is based on processing of time-series for each image pixel using either of three smoothing methods included in TIMESAT: asymmetric Gaussian fits, doublelogistic fits, and Savitzky-Golay filtering. The methods have different properties and are
