Mafic magmatism in the Bakhuis Granulite Belt (western Suriname) : relationship with charnockite magmatism and UHT metamorphism

The Bakhuis Granulite Belt (BGB) is a metamorphic terrain within the Guiana Shield that experienced ultrahigh-temperature (UHT) metamorphism at 2.07–2.05Ga. In the southwest of the BGB, the Kabalebo charnockites were emplaced at ca. 1.99Ga and thus postdate UHT metamorphism by at least 60Myr. Two generations of gabbroic intrusions have been recognized within the BGB, which could act as a heat sour

Dissecting platelet proteomics to understand the pathophysiology of immune thrombocytopenia : studies in mouse models

Immune thrombocytopenia (ITP) is an autoimmune disease characterized by enhanced platelet clearance and defective platelet production. Diagnosis by exclusion and trial-and-error treatment strategies is common practice, and despite the advancement in treatment options, many patients remain refractory. Although the existence of different pathophysiological entities is acknowledged, we are still far

Tyr-701 is a new regulatory site for neurotrophin receptor TrkA trafficking and function

Tropomyosin-related kinase A (TrkA) receptor mediates the effects exerted by nerve growth factor on several subpopulations of neuronal cells. Ligand binding to TrkA induces receptor autophosphorylation on several tyrosine residues and the activation of signaling cascades. In this study, we describe a new site relevant for TrkA regulation, the tyrosine 701 (Y701), which is important for receptor tr

Dynamic expression of HOPX in alveolar epithelial cells reflects injury and repair during the progression of pulmonary fibrosis

Mechanisms of injury and repair in alveolar epithelial cells (AECs) are critically involved in the progression of various lung diseases including idiopathic pulmonary fibrosis (IPF). Homeobox only protein x (HOPX) contributes to the formation of distal lung during development. In adult lung, alveolar epithelial type (AT) I cells express HOPX and lineage-labeled Hopx+ cells give rise to both ATI an

Regulating Germline Editing in Assisted Reproductive Technology : An EU Cross-disciplinary Perspective

Potential applications of genome editing in assisted reproductive technology (ART) raise a vast array of strong opinions, emotional reactions and divergent perceptions. Acknowledging the need for caution and respecting such reactions, we observe that at least some are based on either a misunderstanding of the science or misconceptions about the content and flexibility of the existing legal framewo

Glutaric aciduria type III : A distinctive non-disease?

Glutaric aciduria type III is a rare metabolic abnormality leading to persistent isolated glutaric acid excretion. We report the clinical and biochemical phenotypes of three affected children. The first patient is a boy with dysmorphic features and a chromosomal deletion (monosomy 6q26-qter) in whom a persistent glutaric aciduria (500mmol/mol creatinine, normal <10) was detected during a routine m

Viremia during pregnancy and risk of childhood leukemia and lymphomas in the offspring: Nested case-control study.

A possible role for infections of the pregnant mother in the development of childhood acute leukemias and lymphomas has been suggested. However, no specific infectious agent has been identified. Offspring of 74,000 mothers who had serum samples taken during pregnancy and stored in a large-scale biobank were followed up to the age of 15 years (750,000 person years) through over-generation linkages

Time and frequency synchronization scheme for multiuser OFDM

We present a multiuser synchronization scheme for tracking the mobile's uplink time and frequency offsets. It uses the redundancy introduced by the cyclic prefix and does not need additional pilots. We show performance results of an orthogonal frequency division multiplexing (OFDM)-based radio interface based on the universal mobile telecommunication system (UMTS) parameters. For a UMTS-typical mo

No survival benefit associated with routine surveillance imaging for Hodgkin lymphoma in first remission: a Danish-Swedish population-based observational study.

The use of routine imaging for patients with classical Hodgkin lymphoma (HL) in complete remission (CR) is controversial. In a population-based study, we examined the post-remission survival of Danish and Swedish HL patients for whom follow-up practices were different. Follow-up in Denmark included routine imaging, usually for a minimum of 2 years, whereas clinical follow-up without routine imagin

Evolution of conventional communication : A cross-cultural study of pantomimic re-enactments of transitive events

This study addresses the postulate of non-conventionality of pantomime, inherent in pantomimic scenarios of language origin. Since lack of semiotic conventions does not preclude micro-conventions resulting from cultural differences, pantomimes should be easier to interpret when the actor and recipient share the same culture than between two different cultures. In the study, Italian and Polish amat

Enhanced orbital anisotropy through the proximity to a SrTi O3 layer in the perovskite iridate superlattices

We have used angle-dependent soft x-ray absorption spectroscopy (XAS) at the O K edge and first-principles calculations to investigate the electronic structures of iridate-based superlattices (SrIrO3)m/(SrTiO3) (m=1, 2, 3, and ∞). We focus on the pre-edge Ir 5d t2g-O 2p orbital hybridization feature in the XAS spectra. By varying the measurement geometry relative to the incident photon polarizatio

Utilisation of biomass for the supply of energy carriers

Because biomass is a widely available, renewable resource, its utilisation for the production of energy has great potential for reducing CO2 emissions and thereby preventing global warming. In this mini-review the `state of the art' of several fermentation processes is discussed, starting with the most advanced process of ethanol production. This is followed by methane production, an established p

Molecular Investigations of high-risk Mantle Cell Lymphoma : Genetic factors and the impact of the microenvironment

Mantle cell lymphoma (MCL) is an aggressive disease, with variable clinical course and heterogenous molecular characteristics. In this thesis, which is based upon six original papers, we aimed to understand MCL deregulations, both at intrinsic and extrinsic levels, to identify companion biomarkers that would allow patient stratification. With the aim to bridge the gap between research and clinical

Adjuvants in fungicide formulations can be skin sensitizers and cause different types of cell stress responses

New approaches based on -omics technologies can identify biomarkers and processes regulated in response to xenobiotics, and thus support toxicological risk assessments. This is vital to meet the challenges associated with “cocktail effects”, i.e. combination effects of chemicals present simultaneously in a product, our environment, and/or our body. For plant protection products (PPPs), investigati

Dynamically Reconfigurable Architectures for Real-time Baseband Processing

Motivated by challenges from today's fast-evolving wireless communication standards and soaring silicon design cost, it is important to design a flexible hardware platform that can be dynamically reconfigured to adapt to current operating scenarios, provide seamless handover between different communication networks, and extend the longevity of advanced systems. Moreover, increasingly sophisticated

Design of Oversampled Uniform DFT Filter Banks with Reduced Inband Aliasing and Delay Constraints

Subband adaptive filters have been proposed to avoid the drawbacks of slow convergence and high computational complexity associated with time domain adaptive filters for acoustic echo cancellation. Subband processing introduces transmission delays caused by the filter bank and signal degradations due to aliasing effects. One efficient way to reduce the aliasing effects is to allow a higher sample

Measuring Niche-Associated Metabolic Activity in Planktonic and Biofilm Bacteria

Most pathobionts of the respiratory tract form biofilms during asymptomatic colonization to survive and persist in this niche. Environmental changes of the host niche, often resulting from infection with respiratory viruses, changes of the microbiota composition, or other host assaults, can result in biofilm dispersion and spread of bacteria to other host niches, resulting in infections, such as o

Radial Neck Fractures in Children and Adolescents : An Examination of Operative and Nonoperative Treatment and Outcomes

BACKGROUND: Although most pediatric radial neck fractures can be treated with either immobilization alone or closed reduction and immobilization, a small subset result in permanent loss of motion despite surgical management. We sought to characterize the most problematic fractures and correlate final outcomes with both presenting fracture characteristics and the reduction achieved through surgical
