In this letter, we show the results achieved using a hydrogenated amorphous silicon photosensor for a "label-free" deoxyribonucleic acid (DNA) analysis based on the measurements of the absorbance in the ultraviolet range. The optimization of the sensor str ...
We investigate the average erasure probability of the belief propagation algorithm over the binary erasure channel (BEC) for various finite-length low- density parity-check (LDPC) ensembles. In particular, we give tight upper bounds on the "error floor", i ...
We studied the factors that determine the differing growth requirements of low-iron-tolerant (LIT) versus high-iron-dependent (HID) cells for extracellular nontransferrin iron. The growth of LIT cells HeLa and THP-1, when transferred from transferrin (5 mi ...
BACKGROUND: Existing animal models of anemia inadequately reflect the hematocrit usually present in chronic renal failure (CRF) patients and do not permit long-term treatment studies. The transgenic mouse strain 134.3LC (Epo-TAg(H)) displays a severe chron ...
Iron-regulatory proteins (IRPs) 1 and 2 are closely related molecules involved in animal iron metabolism. Both proteins can bind to specific mRNA regions called iron-responsive elements and thereby control the expression of proteins involved in the uptake, ...
Duodenal enterocytes adjust intestinal iron absorption to the body's state of iron repletion. Here we tested how iron supply from the blood modulates the RNA-binding activity of iron regulatory proteins (IRP-1 and IRP-2) in immature duodenal rat enterocyte ...
Sediment analysis using wet extraction techniques and model simulations were carried out to investigate the role of ferric iron during biodegradation of dissolved petroleum hydrocarbon compounds at a field site in Perth, Western Australia. Sediment cores w ...
Cognitive deficits in human infants at risk for gestationally acquired perinatal iron deficiency suggest involvement of the developing hippocampus. To understand the plausible biological explanations for hippocampal injury in perinatal iron deficiency, a n ...
Many human anaemias are caused by defects in haemoglobin synthesis. The zebrafish mutant sauternes (sau) has a microcytic, hypochromic anaemia, suggesting that haemoglobin production is perturbed. During embryogenesis, sau mutants have delayed erythroid ma ...
We studied the effects of iron supplied as transferrin-bound iron and iron supplied as non-transferrin iron on transferrin receptor expression by human cell lines. Defined conditions of iron supply were represented by (i) 5 microg/ml of iron-saturated tran ...
