Blastic plasmacytoid DC neoplasm (BPDCN) is a rare haematopoietic malignancy with an aggressive behaviour. We evaluated five patients allografted as consolidative treatment with an unrelated donor in first or subsequent remission. Four patients received a reduced intensity-conditioning regimen because of age or co-morbidities. As the stem cell sources, two umbilical ...

Noble metallic nanostructures exhibit a phenomenon known as surface-enhanced Raman scattering (SERS) in which the Raman scattering cross-sections are dramatically enhanced for the molecules adsorbed thereon. Due to their wide accessible potential range in aqueous solutions and the high biocompatibility, Au supports are preferred for spectro-electrochemical investigations. But the optical ...

We designed a facile one-pot method to synthesize iron oxide/activated carbon nanotubes (IO/ACNTs) using as-prepared carbon nanotubes (APCNTs) modified by alkali solid-activation. The open-ended CNTs and iron oxide loading could be realized in one step. The resulting IO/ACNT hybrids, as an anode material for lithium-ion batteries (LIBs), exhibited high reversible ...

The plant hormones cytokinins (CKs) regulate multiple developmental and physiological processes in Arabidopsis thaliana. Responses to CKs vary in different organs and tissues, e.g., the response to CKs has been shown to be opposite in shoot and root samples. However, the tissue-specific targets of CKs and the mechanisms underlying such ...

Patients on antithrombotic therapy (ATT) have the highest risk of ongoing bleeding and mortality. Hemospray (Cook Medical, Winston-Salem, North Carolina, USA) is a novel hemostatic agent for the treatment of upper gastrointestinal bleeding (UGIB). Initial reports on its use appear promising in terms of initial hemostasis and rebleeding rates. It ...

When stressed, people typically show elevated rates of displacement behaviour - activities like scratching and face touching that seem irrelevant to the ongoing situation. Growing evidence indicates that displacement behaviour may play a role in regulating stress levels, and thus may represent an important component of the coping response. Recently, ...

Introduction: Regulation of phosphate homeostasis is essential for mineralization and enchondral ossification. Fibroblast growth factor 23 (FGF23) and its obligatory co-receptor Klotho (KL) play a key role in this process by influencing both renal phosphate reabsorption and vitamin D metabolism. In disease, excessive action of FGF23 leads to hypophosphatemic rickets ...

BACKGROUND AND OBJECTIVE:Adults born preterm score lower on performance-based tests of executive functioning (EF) than their term-born peers. These test scores do not necessarily translate to application of these skills in an everyday environment. The objective of the study was to test differences between very low birth weight (VLBW; <1500 ...

The applicability of gallium-based liquid metal alloy has been limited by the oxidation problem. In this paper, we report a simple method to remove the oxide layer on the surface of such alloy to recover its non-wetting characteristics, using hydrochloric acid (HCl) vapor. Through the HCl vapor treatment, we successfully ...

Recent electrophysiological evidence has shown that perceptual load and negative affective state can produce very similar, early-attention gating effects in early visual areas, modulating the processing of peripheral stimuli. Here we assessed the question of whether or not these modulatory effects of perceptual load and negative affect (NA) lead to ...

Marine-origin Brucella infections and serologic evidence of exposure have been documented in multiple cetacean species. A dolphin-specific indirect enzyme-linked immunosorbent assay (ELISA) was developed to screen bottlenose dolphin sera for anti-Brucella antibodies. A total of 131 serum samples collected over a 2 to 18 yr period from 6 bottlenose dolphins ...

The epidemiology of vector-borne pathogens is largely determined by the host-choice behaviour of their vectors. Here, we investigate whether a Plasmodium infection renders the host more attractive to host-seeking mosquitoes. For this purpose, we work on a novel experimental system: the avian malaria parasite Plasmodium relictum, and its natural vector, ...

Allopatric speciation may be the principal mechanism generating new species. Yet, it remains difficult to judge the generality of this process because few studies have provided evidence that geographic isolation has triggered the development of reproductive isolation over multiple species of a regional fauna. Here, we first combine results from ...

Recently, several studies reported a relationship between immune system activation and anger expression. Consequently, the aim of this study was to explore immunitary molecular mechanisms that potentially underlie anger expression. To this end, we applied the Frustration-Aggression Theory in a contact sport model, utilizing the nearing of sporting events to ...

Recent theories in sexuality highlight the importance of automatic and controlled attentional processes in viewing sexually relevant stimuli. The model of Spiering and Everaerd (2007) assumes that sexually relevant features of a stimulus are preattentively selected and automatically induce focal attention to these sexually relevant aspects. Whether this assumption proves ...

Convergent phenotypic evolution may or may not be associated with convergent genotypic evolution. Agricultural weeds have repeatedly been selected for weed-adaptive traits such as rapid growth, increased seed dispersal and dormancy, thus providing an ideal system for the study of convergent evolution. Here, we identify QTL underlying weedy traits and ...

ABSTRACT: BACKGROUND: Using reduced doses of Cyclosporine A immediately after heart transplantation in clinical trials may suggest benefits for renal function by reducing serum creatinine levels without a significant change in clinical endpoints. However, these trials were not sufficiently powered to prove clinical outcomes. METHODS: In a prospective, multicentre, open-label, ...

N-alkyl substituted pyrroloindacenodithiophene (PIDT) and their phenyl substituted derivatives were synthesized. Their single-crystal structures, electrochemical and spectroscopic properties were investigated. Experimental results showed PIDT displayed strong electron-donating properties, reversible redox behaviors and strong fluorescence, and could be controlled to oxidize to radical cation and dication with distinctive optical changes. These ...
