We studied the effects of lead pollution on testate amoebae communities living on Sphagnum fallax by growing this moss under controlled conditions. A progressive series of lead (Pb) concentration was used in the growing solution of the mosses: 0 (control), 625 and 2,500 microgL(-1). The mosses were sampled and analysed for accumulated Pb and testate amoeba communities after 0, 6, 12, and 20 wee...

The distribution of lead (Pb) accumulated in the pteridophyte Blechnum niponicum, a Pb-hyperaccumulator, was measured using synchrotron-radiation micro X-ray fluorescence (SR-micro-XRF) at BL37XU of SPring-8. From two-dimensional (2D) imagings of Pb at the root, petiole, leaf vein, pinna epidermis and sorus in the Blechnum niponicum, the mechanism for the transportation and accumulation of Pb c...

Concentrations and isotopic compositions of lead in the total and mobile (acid-soluble and carbonatebound) forms were determined in remote and roadside Chestnut soils in the dry steppe region of Low Volga, Russia. As a reference to evaluate the level of modern soil contamination with lead, we used ancient soil buried under a Bronze Age kurgan about 4500 years ago. In comparison with buried soil...

We have investigated U-Pb discordance and oxygen isotopic composition of zircon using high– spatial resolution !O measurement by ion microprobe. !O in both concordant and discordant zircon grains provides an indication of the relationship between fluid interaction and discordance. Our results suggest that three characteristics of zircon are interrelated: (1) U-Pb systematics and concomitant age...

The mechanism of Pb-induced disruption of Na(+) and Cl(-) balance was investigated in the freshwater rainbow trout (Oncorhynchus mykiss). Na(+) and Cl(-) influx rates were reduced immediately in the presence of 2.40 +/- 0.24 and 1.25 +/- 0.14 muM Pb, with a small increase in efflux rates occurring after 24-h exposure. Waterborne Pb caused a significant decrease in the maximal rate of Na(+) infl...

The fluctuations in pseudorapidity density are well described by Fritiof and IRIS, model for a bulk of the data at a few high multiplicity events remain unexplained. In these events, the estimated energy density is within the range of values predicated for the onset of the deconfinement phase transition. It is important to know whether fluctuations are, in fact, of statistical nature or geometr...

The ATLAS Collaboration is embarked in a detailed study of the dense and opaque extended system formed in Pb-Pb collisions at LHC. Comparisons of jet yields obtained in different classes of events confirm the presence of strong energy loss of partons in the medium at this energy. The study of jet shapes provides detailed information on the flow of energy as partons traverse the medium.

BACKGROUND Status epilepticus (SE) is a neurological emergency condition. Intravenous phenobarbital (PB) is recommended for refractory SE treatment. However, intravenous PB is unavailable in Thailand. Enteral PB has been shown to be effective in SE children. METHODS In adult SE patients, the efficacy of enteral PB as an adjunctive therapy has been reported. This is a case series of adult SE p...
