1. The dephosphorylation of 3'-AMP, 3'-dAMP, 3'-CMP and 3'-dCMP was studied in the postmicrosomal supernatant of rat spleen and liver. In both organs 3'-AMP and 3'-dAMP were dephosphorylated at an appreciable rate, in both the presence and the absence of Mg(2+). The pH optimum for this dephosphorylation was in the range 4.5-5.0. 3'-CMP and 3'-dCMP were very slowly degraded, though the activity ...

In recent years there has been renewed activity in the literature concerning the 1,3-dipolar cycloaddition reaction (1,3-DCR) of organic azides (R-N₃) with alkynes (R'-C≡CH) to form 1,2,3-triazoles, i.e. the Huisgen synthesis. The use of catalytic Cu(I) leads to a dramatic rate enhancement (up to 10(7)-fold) and exclusive synthesis of the 1,4-disubstituted 1,2,3-triazole product. The reaction, ...

Fungi Mikoriza Arbuskular (FMA) berasosiasi dengan sebagian besar tanaman dan mempunyai peranan yang sangat penting dalam meningkatkan pertumbuhan produktivitas tanaman. Penelitian ini bertujuan untuk menguji efektivitas inokulum FMA terhadap 2 jenis kehutanan (Samanea saman Calliandra surinamensis) 1 pertanian (Zea mays) di tanah tailing. Percobaan pot Rancangan Acak Lengkap dilakukan screen h...

As sessile organisms, plants have evolved effective mechanisms to protect themselves from environmental stresses. Damaged (i.e., wounded) plants recognize a variety of endogenous molecules as danger signals, referred to as damage-associated molecular patterns (DAMPs). ATP is among the molecules that are released by cell damage, and recent evidence suggests that ATP can serve as a DAMP. Although...

Persistent oscillation in constant conditions is a defining characteristic of circadian rhythms. However, in plants transferred into extended dark conditions, circadian rhythms in mRNA abundance commonly damp in amplitude over two or three cycles to a steady state level of relatively constant, low mRNA abundance. In Arabidopsis, catalase CAT3 mRNA oscillations damp rapidly in extended dark cond...

Branding has become immensely important for digital based organizations in the recent years because electronic Re tailing are identical and difficult to differentiate their product services is highly attracting public, make use of organization especially E-Tailing. Customer play an role, with increased competition Electronic Retailing sector, For that, developing implementing customer centric s...

Damage-associated molecular pattern molecules (DAMPs) signal the presence of tissue damage to induce immune responses in plants and animals. Here, we report that High Mobility Group Box 3 (HMGB3) is a novel plant DAMP. Extracellular HMGB3, through receptor-like kinases BAK1 and BKK1, induced hallmark innate immune responses, including i) MAPK activation, ii) defense-related gene expression, iii...

world apricot (prunus armeniaca l.)  production is increasing steadily due to breeding of new high yielding cultivars in different countries. more recently, breeding programs have been modified according to consumers’ demands and also improvement in resistance to diseases (sharka, monilinia etc.), frost damages, and determination of self-(in) compatibility. in this study, fourteen apricot breed...

In addition to the Poiseuille effect, a so-called temporal effect was proposed recently to elucidate the commonly observed tailing peak signals of flow injection analysis (FIA). A multi-channel absorbance detector was used in this study to obtain the FIA peaks on both the spatial and temporal coordinates. The temporal effect was analyzed by comparison of the profiles between the experimental an...

A pot experiment was conducted to investigate the feasibility of growing energy sugarcane (Saccharum spp.) in three different metal mine tailings (Cu, Sn and Pb/Zn tailings) amended with uncontaminated soil at different mixing ratios. The results indicated that sugarcane was highly tolerant to tailing environments. Amendments of 20% soil to Sn tailings and 30% soil to Cu tailings could increase...
