Densely interconnected transcriptional circuits control cell states in human hematopoiesis

Though many individual transcription factors are known to regulate hematopoietic differentiation, major aspects of the global architecture of hematopoiesis remain unknown. Here, we profiled gene expression in 38 distinct purified populations of human hematopoietic cells and used probabilistic models of gene expression and analysis of cis-elements in gene promoters to decipher the general organizat

A Comprehension of Spinoza's God : through the Dichotomy of Labels

The 17th century philosopher Spinoza is known for his concept of God as One Substance, God or Nature and therefore considered as a monist and categorized as a naturalist. He has been labeled an atheist and God-intoxicated man, as well as a determinist and pantheist, which I perceive to be dichotomies. The problem, as I see it, is that Spinoza’s philosophy and concept of God has mainly been interpr

Outlining an analytical framework for mapping research evaluation landscapes

This paper suggests an infrastructure perspective, as suggested by Star and Bowker (2006), as an analytical framework for studying the research evaluation landscape. An infrastructure is suggested to be understood, not as a concrete technology, but as a system of contextual factors including ‘Actors/Stakeholders’, ‘Technical systems’, and ‘Evaluation practices’. How the framework can be operationaThis paper suggests an infrastructure perspective, as suggested by Star and Bowker (2006), as an analytical framework for studying the research evaluation landscape.

Multiscale modeling approaches of transport phenomena in fuel cells

Modeling is of key importance in fuel cell development beyond the current-state-of-the-art because it is beneficial to understand the mechanisms of various interacting phenomena and effects on the cell performance. It is also hard to measure the local parameters inside fuel cells, particularly inside the small scale functional materials. Modeling and simulation of charge transfer and electrochemic

Functionalization of Recombinant Amelogenin Nanospheres Allows Their Binding to Cellulose Materials

Protein engineering to functionalize the self-assembling enamel matrix protein amelogenin with a cellulose binding domain (CBD) is used. The purpose is to examine the binding of the engineered protein, rh174CBD, to cellulose materials, and the possibility to immobilize self-assembled amelogenin nanospheres on cellulose. rh174CBD assembled to nanospheres ≈35 nm in hydrodynamic diameter, very simila

Age influences inflammatory responses, hemodynamics, and cardiac proteasome activation during acute lung injury

BACKGROUND: Acute lung injury (ALI) is a significant source of morbidity and mortality in critically ill patients. Age is a major determinant of clinical outcome in ALI. The increased ALI-associated mortality in the older population suggests that there are age-dependent alterations in the responses to pulmonary challenge. The objective of this observational study was to evaluate age-dependent diff

Count rate characteristics and image distortion in preclinical PET systems during intratherapeutic radiopharmaceutical therapy imaging

Positron emission tomography (PET) may provide important information on the therapeutic response of radiopharmaceutical therapy (RPT) during therapy. The radiation emission from the RPT radionuclide may disturb the coincidence detection and impair the image resolution. In this study we tested the feasibility to perform intratherapeutic PET on three preclinical PET systems.METHODS: Using (22)Na poi

Environmental and climate reconstruction of the late-glacial-Holocene transition from a lake sediment sequence in Aubrac, French Massif Central : Chironomid and diatom evidence

The analysis of fossil chironomid and diatom assemblages from a sedimentary record from Les Roustières peat bog (Massif Central, France, 1196 m asl) allows the reconstruction of past environmental and climate changes during the late-glacial and early Holocene. Chironomid assemblages showed that the infilling of the palaeolake had commenced during the Oldest Dryas (GS-2b) as suggested by the rapid

Zeolite Beta Formation from Clear Sols : Silicate Speciation, Particle Formation and Crystallization Monitored by Complementary Analysis Methods

The formation of silicate nanoaggregates (NAs) at the very early stages of precursor sols and zeolite beta crystallization from silicate nanoparticles (NPs) are investigated in detail using a combination of different analysis methods, including liquid-state 29Si, 27Al, 14N, and 1H NMR spectroscopy, mass spectrometry (MS), small-angle X-ray scattering (SAXS), X-ray diffraction (XRD), and transmissi

Analysis of 210Pb in water samples with plastic scintillation resins

210Pb is a radioactive lead isotope present in the environment as member of the 238U decay chain. Since it is a relatively long-lived radionuclide (T1/2 = 22.2 years), its analysis is of interest in radiation protection and the geochronology of sediments and artwork. Here, we present a method for analysing 210Pb using plastic scintillation resins (PSresins) packaged in solid-phase extraction colu

Naturvetenskapliga ideal i svensk elektronisk konstmusik

Den här presentationen tar sin utgångspunkt i en idéhistorisk diskussion om relationen mellan naturvetenskapliga ideal och den elektroniska musikens framväxt i Sverige under slutet av 1950-talet. Denna relation markerar i mångt och mycket en ny tidsålder på flera sätt. Inom den modernistiska konstmusiken argumenteras det bland annat att det äger rum en musikestetisk revolution, där exempelvis den

Aspects of prophylactic treatment of hemophilia

Retrospective and prospective studies unambiguously show that prophylactic treatment of severe hemophilia A or B should be started as primary prophylaxis at 1-2 years' of age and ideally before the first joint bleed. The dose and dose frequency should be individually tailored depending on the goal of treatment, venous access and the bleeding phenotype. The circumstances during the first exposures

Inter-subject variability and normal limits of the SITA Standard, SITA Fast, and the Humphrey Full Threshold computerized perimetry strategies, SITA STATPAC

PURPOSE: To establish and evaluate inter-subject variability and normal threshold limits for the new SITA strategies and to compare them with those obtained with the traditional Humphrey Full Threshold algorithm.METHODS: Data from 330 eyes of 330 normal subjects were collected at 10 centres in order to establish limits of normality for the new SITA strategies and thus, to make it possible to subje
