Interest in quotidian (daily) hemodialysis (HD) is growing. Some advocate short-hours high-efficiency daily HD (SDH) and others long-hours slow-flow nocturnal HD (NH) while the patient is asleep, both being used 5 to 7 d/week. The London Daily/Nocturnal Hemodialysis Study was the first attempt to obtain data of SDH and NH that may be compared with conventional thrice weekly HD (CH). This was a ...

Advanced photolithography developed for the semiconductor industry has been used to fabricate interdigitated microelectrode arrays that pass steady-state limiting currents of up to 230 nArmM analyte — 2.5 times more than the most sensitive interdigitated array built to date, and exhibit response times of ;5 ms. This performance results from the small interelectrode gap and the large active area...

O objetivo desse trabalho foi produzir mudas de espécie florestal da caatinga (Sabiá – Mimosa caesalpiniifolia Benth) submetidas a diferentes níveis irrigação, no viveiro do Centro Saúde e Tecnologia Rural/CSTR, Campus Patos PB. Seguiu-se um delineamento inteiramente casualisado (DIC), com 5 irrigação (L) acordo as necessidades hídricas das plantas (NH), sendo os seguintes: L1 (100%NH); L2 (80%...

A series of aluminium derivatives containing substituted bidentate and symmetrical tridentate pyrrolyl ligands, [C(4)H(3)NH(2-CH(2)NH(t)Bu)] and [C(4)H(2)NH(2,5-CH(2)NH(t)Bu)(2)], in toluene or diethyl ether were synthesized. Their reactivity and application for the ring opening polymerization of ε-caprolactone have been investigated. The reaction of AlMe(3) with one equiv. of [C(4)H(3)NH(2-CH(...

To assess differences in the receipt of preventive health services by race/ethnicity among older women with endometrial cancer enrolled in Medicare, we conducted a retrospective population-based cohort study of women diagnosed with endometrial cancer from 2001 to 2011 in the Surveillance Epidemiology and End Results (SEER)-Medicare database. Women with stage I or II endometrial cancer of epithe...

Nitrogen excreted in dairy manure can be potentially transformed and emitted as NH, which can create livestock and human respiratory problems and be an indirect source of NO. The objectives of this study were to: (i) investigate environmental factors influencing NH emissions from dairy housing; and (ii) identify key explanatory variables in the NH emissions prediction from dairy housing using a...

ABSTRACT We present the first characterization of K(+) optimization of N uptake and metabolism in an NH(4)(+)-tolerant species, tropical lowland rice (cv. IR-72). (13)N radiotracing showed that increased K(+) supply reduces futile NH(4)(+) cycling at the plasma membrane, diminishing the excessive rates of both unidirectional influx and efflux. Pharmacological testing showed that low-affinity NH...

It is proposed that the glycine precursor NH(2)CH(2)CN may be synthesised in interstellar dust clouds by the radical combination reactions NH(2)˙ + ˙CH(2)CN → NH(2)CH(2)CN (ΔG = -302 kJ mol(-1)) and/or NH(2)CH(2)˙ + ˙CN → NH(2)CH(2)CN (ΔG = -414 kJ mol(-1)). All calculations at the CCSD(T)/aug-cc-pVDZ//B3LYP/6-31+G(d) level of theory. This paper extends that concept to radical/radical coupling ...
