background: natural methods of wastewater treatment, such as wetlands, are simple, cheap and acceptable for developing countries, especially small and remote cities. the aim of this study was to evaluate the efficiency of typha latifolica in subsurface flow constructed wetland for wastewater treatment. methods: in this experimental research, the efficiency of typha latifolica in subsurface flow...

BACKGROUND Kidney hypertrophy is stimulated by both partial nephrectomy and NH(4)Cl administration. Also, parathyroidectomy (PTX) has been reported to prevent kidney hypertrophy induced by a high protein diet. Our goal was to determine in the azotaemic rat: (i) the combined effects of NH(4)Cl administration and dietary phosphorus on the development of kidney hypertrophy and calcium deposition i...

This work reports that ammonia (NH(3)) can be used as an efficient co-reactant for tris(2,2'-bipyridine)ruthenium(II) (Ru(bpy)(3)(2+)) electrochemiluminescence (ECL) in ionic liquids (ILs), on the basis of which a signal-on ECL sensor for directly detecting gaseous NH(3) has been developed. The NH(3) ECL sensor has a very high sensitivity, with a detection limit of 10 ppt NH(3) (at signal-to-no...

The purpose of this study was to determine the prevalence of pancreatic nodular hyperplasia (NH) and its relation to age in the dog. A total of 101 dogs were enrolled. The pancreas was evaluated by histology and hyperplastic lesions were detected and scored. Age was recorded from the medical records. Correlation of age with inflammation and presence of hyperplastic lesions was evaluated. Of the...

The framework of the title compound, {(NH(3)CH(2)CH(2)NH(3))[CdCl(4)]}(n), is built upon layers parallel to (100) made up from corner-sharing [CdCl(6)] octa-hedra. NH(3)CH(2)CH(2)NH(3) (2+) cations are situated between the layers and are linked to the layers via an N-H⋯Cl hydrogen-bonding network. The Cd atom is located on an inversion centre and the coordination environment is described as hig...

Alkylation of [{Ti(η(5)-C(5)Me(5))(μ-NH)}(3)(μ(3)-N)] with MeOTf occurs at the imido ligands to produce the methylamido derivative [Ti(3)(η(5)-C(5)Me(5))(3)(μ(3)-N)(μ-NH)(2)(μ-NHMe)(OTf)] which readily rearranges to form the methylimido complex [Ti(3)(η(5)-C(5)Me(5))(3)(μ(3)-N)(μ-NH)(μ-NH(2))(μ-NMe)(OTf)].

Here we show that in aging Saccharomyces cerevisiae (budding yeast) cells, NH(4) (+) induces cell death associated with shortening of chronological life span. This effect is positively correlated with the concentration of NH(4) (+) added to the culture medium and is particularly evident when cells are starved for auxotrophy-complementing amino acids. NH(4) (+)-induced cell death is accompanied ...
