A donor-acceptor compound based on N,N,N',N'-tetramethyl-p-phenylene-diamine and 1,2,4,5-tetracyanobenzene (TMPD:TCNB) has been synthesized. The crystal structure of the black 1:1 complex formed between TMPD and TCNB has been determined by single crystal X-ray diffraction at room temperature. The compound crystallizes in the triclinic space group P-1 with cell dimensions: a = 7.4986(15) å, b =7...

The crystal structures of ds-(«-Bu4N)2[ReBr4(NCS)2] (1) (triclinic, space group Pi, a = 11.475(6), b = 20.096(16), c = 22.144(11) A, a = 110.56(6), ß = 92.97(5), 7 = 99.77(7)°, Z = 4), m-(n-Bu4NMReBr4(NCSe)i] (2) (triclinic, space group PI, a = 11.527(3), b = 20.237(7), c = 22.07(2) Ä, a = 110.05(4), ß = 93.86(6), 7 = 99.49(4)°, Z = 4) and cis-{nBu4N)2[ReBr4(NCS)(NCSe)] (3) (triclinic, space gr...

Page 4 PSG Request for Datamining Abstract Parkinson’s disease (PD) has many paradoxes. For example, although smoking is highly associated with cancer and cardiovascular disease, smoking is associated with a much lower risk of PD (which itself is associated with a lower occurrence of cardiovascular disease). Whereas the apolipoprotein E ε4 allele is associated with higher risk of Alzheimer’s di...

We studied the uptake metabolism, and distribution of a fluorescent analog of CDP-diacylglycerol [cytidine diphosphate-1, 2-oleoyl, (N-(4-nitrobenzo-2-oxa-1,3-diazole) aminocaproyl) diacylglycerol; CDP-NBD-DAG]. When cells were incubated with CDP-NBD-DAG for 60 min at 11 degrees C and washed, the fluorescent lipid was localized to the plasma membrane. However, upon warming to 37 degrees C, the ...

The importance of SPX domain-encoding proteins to phosphate (Pi) homeostasis and signaling pathways has been well-documented in rice and Arabidopsis. However, global information and responses of SPX members to P stress in allotetraploid Brassica napus, one of the world's major oil crops that is sensitive to P deficiency, remain undefined. We identified a total of 69 SPX domain-containing genes ...

The development of antiretroviral (ARV) drugs and their use in human immunodeficiency virus type 1 (HIV-1) has led to the effective control of HIV replication in infected patients. However the emergence of resistant HIV-1 strains still remains a problem. Literature has shown that mutations may accumulate in the protease (PR) and gag regions of HIV-1 patients who fail therapy with protease inhib...

the padmakar-ivan (pi) index is a wiener-szeged-like topological index which reflectscertain structural features of organic molecules. the pi index of a graph g is the sum of alledges uv of g of the number of edges which are not equidistant from the vertices u and v. inthis paper we obtain the second and third extremals of catacondensed hexagonal systems withrespect to the pi index.

To evaluate the characteristics of atmospheric particle retention by plant leaves during the tourism season in Buddhism-based scenic areas, plants distributed in the core area of the Mount Wutai scenic area were selected for study: Populus davidiana (Po. davidiana), Rosa hugonis Hemsl. (R. hugonis), Betula platyphylla Suk. (B. platyphylla), Rosa xanthina Lindl. (R. xanthina), Periploca sepium B...
