Thus, copper induced the synthesis of ascorbate, glutathione and PCs in U. compressa suggesting that these compounds are involved in copper tolerance. Interestingly, U. compressa is, until now, the only ulvophyte

showing ASC, GSH and PCs synthesis in response to copper excess. (C) 2011 Elsevier Masson SAS. All rights reserved.”
“We report the cases of 3 children with plastic Apoptosis Compound Library cell line bronchitis associated with 2009 H1N1 influenza virus infection. These 3 children shared common clinical and radiologic features: rapid and progressive respiratory distress with whole lung atelectasis on chest radiograph. In children with severe respiratory symptoms accompanied by H1N1 influenza, plastic bronchitis should be considered.”
“Metastable paramagnetic face-centered cubic (fcc) Fe films grown on a Cu(100) single crystal at room temperature can be transformed to the ferromagnetic body-centered cubic (bcc) structure by ion irradiation. We have employed this technique to write small ferromagnetic patches by Ar+ irradiation through a gold coated SiN mask with regularly arranged 80-nm diameter holes, which was placed on top of the as-prepared fcc Fe films. Nanopatterning was performed on both 8-monolayer (ML) Fe films grown in ultrahigh vacuum as well as 22-ML films stabilized by dosing carbon monoxide during growth. The structural transformation

of these nano-patterned films was investigated GSK 4529 using scanning tunneling microscopy. In both 8 and 22-ML fcc Fe films, the Cell Cycle inhibitor bcc needles are found to

protrude laterally out of the irradiated part of the sample, limiting the resolution of the technique to a few 10 nm. The magnetic transformation was confirmed by magnetic force microscopy. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3609078]“
“In general, wild tomato species are more salt tolerant than cultivated species, a trait that is related to enhanced Na+ accumulation in aerial parts in the wild species, but the molecular basis for these differences is not known. Plant NHX proteins have been suggested to be important for salt tolerance by promoting accumulation of Na+ or K+ inside vacuoles. Therefore, differences in expression or activity of NHX proteins in tomato could be at the basis of the enhanced salt tolerance in wild tomato species. To test this hypothesis, we studied the expression level of four NHX genes in the salt sensitive cultivated species Solanum lycopersicum L cv. Volgogradskij and the salt tolerant wild species Solanum pimpinelifolium L in response to salt stress. First, we determined that in the absence of salt stress, the RNA abundance of LeNHX2,3 and 4 was comparable in both species, while more LeNHX1 RNA was detected in the tolerant species. LeNHX2 and LeNHX3 showed comparable expression levels and were present in all tissues, while LeNHX4 was expressed above all in stem and fruit tissues.
