The presence of phytoplankton, like other particulate organic matter, can interfere with the effects of hydrophobic contaminants such as pyrethroid pesticides. However, the reduction or elimination of toxicity by algae added as food during testing is not taken into account in standard US EPA whole effluent toxicity (WET) zooplankton tests. ...

At present there are no nephrology facilities in Greenland. Greenlandic patients with renal failure needing dialysis thus have to travel to Denmark to obtain treatment. For patients in haemodialysis this necessitates a permanent residence in Denmark. Our study was aimed at examining Greenlanders' preferences for establishing nephrology facilities in Greenland ...

BACKGROUND: Impairments in gluconeogenesis have been implicated in the pathophysiology of fasting hypoglycemia in medium-chain acyl-CoA dehydrogenase deficiency. However, whole body glucose and fat metabolism have never been studied in vivo. METHODS: Stable isotope methodology was applied to compare fat and glucose metabolism between four adult patients with MCADD and ...

Seasonal time constraints can pose strong selection on life histories. Time-constrained animals should prioritise fast development over predation risk to avoid unfavourable growing conditions. However, changes in phenology could alter the balance between anti-predator and developmental needs. We studied variation of anti-predator strategies in common frog (Rana temporaria) tadpoles in ...

We describe here the determination of the alkylation rate of a set of organic superbases by iodomethane in DMF using a microfluidic continuous flow reactor. Surprisingly, log k(Alkylation) follows the inverse trend of pK(BH+) of the base. Mayr's equation allows a more quantitative approach. From a synthetic point of view, ...

INTRODUCTION: The essential issue in conservative treatment is the quality in breast preservation. When risk factors for local relapse exist, a tumour bed boost is required, but the boost choice remains controversial. Prospectively, we studied long-term toxicity, cosmetic outcome and prognostic factors. MATERIALS AND METHODS: After conservative treatment, 115 patients ...

PURPOSE: Postoperative hypocalcaemia has been reported to be more common after total thyroidectomy (TT) for Graves' disease than after TT for benign atoxic multinodular goitre (MNG). The reasons for this potential association are not clear. In the present study, the frequency and risk factors of hypocalcaemia after TT for Graves' ...

Fast and reversible photonic-bandgap tunability is achieved in silica artificial opals by local heating. The effect is fully reversed as is heat rapidly dissipates through the non-irradiated structure without active cooling, and water is readsorbed. The performance is strongly enhanced by decreasing the photoirradiated opal volume, allowing bandgap shifts of ...

Previous studies have shown that 17β-estradiol has a pivotal function by blocking voltage-gated K(+) (Kv) channels in several different types of cells such as cardiac myocytes and neurons. Outward Kv currents can also be measured in osteoblasts, although little is known about the effects of 17β-estradiol on these currents. In ...

Matrix-assisted laser desorption/ionization (MALDI) is now a mature method allowing the identification and, more challenging, the quantification of biopolymers (proteins, nucleic acids, glycans, etc). MALDI spectra show mostly intact singly charged ions. To obtain fragments, the activation of singly charged precursors is necessary, but not efficient above 3.5 kDa, thus ...

Activation of CD8(+) cytotoxic T cells is crucial for the adaptive immune response against viral infections and the control of malignant transformed cells. Together with activation of costimulatory molecules like CD3 and CD28, CD8(+) T cells need activation of their unique T cell receptor via recognition of foreign peptide epitopes ...

BACKGROUND: Studies investigating early developmental factors in relation to psychopathology have mainly focused on schizophrenia. The personality dimension of neuroticism seems to be a general risk factor for psychopathology, but evidence on associations between early developmental precursors and personality traits is almost non-existent. This study is therefore the first to ...

Non-alcoholic steatohepatitis is a burgeoning health problem. To diagnose NASH with magnetic resonance imaging (MRI), an effective contrast agent, a stable suspension of superparamagnetic Fe(3)O(4) nanoparticles, were newly developed. The negatively charged Fe(3)O(4) nanoparticles were coated with positive chitosan (CS) firstly, and then assembled with poly(vinyl acetate-methylacrylic acid) (P(VAc-MAA)). Transmission ...

Adoptive transfer of virus-specific donor-derived CD8 T cells is a therapeutic option to prevent cytomegalovirus (CMV) disease in recipients of hematopoietic cell transplantation. Due to their high coding capacity, human as well as animal CMVs have the potential to encode numerous CD8 T cell epitopes. Although the CD8 T cell ...
