A batch sorption system using tree fern as biosorbent was investigated to remove Basic Red 13 from aqueous solutions. The system variables studied include sorbent particle size and temperature and results revealed the potential of tree fern, an agriculture product, as a low-cost sorbent. The Lan...

1.1. Injection of 2,2-difluoroputrescine (DFPut) into the yolk sac of chick embryos causes the formation of 6,6-difluorospermidine (6,6DFSpd) and 6,6-difluorospermine (6,6DFSpm), demonstrating that the difluoroanalogs of putrescine and spermidine are in vivo substrates of spermidine and spermine...

Coordination polymers, [–M(L)(μ-dppp/dppb/dpph)–]n(X)n, (M = Cu(I), Ag(I); L, N-{(2-pyridyl)methyliden}-6-coumarin; X = NO3− or ClO4−; dppp, 1,3-bis(diphenylphosphino)propane; dppb, 1,4-bis(diphenylphosphino)butane; dpph, 1,6-bis(diphenylphosphino)hexane) have been spectroscopically character...

Structural modifications of nicotinamide, a form of vitamin B3, gave rise to a series of compounds (8aa–8ce) that exhibit activities as type I positive allosteric modulators (PAMs) of human α7 nAChR expressed in Xenopus oocytes in two-electrode voltage clamp assay. The compound 8ai was a poten...

Retinoic acid inducible gene I (RIG-I) can recognize influenza viruses and evoke the innate immune response. RIG-I is absent in the chicken genome, but is conserved in the genome of ducks. Lack of RIG-I renders chickens more susceptible to avian influenza infection, and the clinical symptoms are...

In many industrial applications, (CF3)2CFCN has been suggested as SF6 substitute, which possess a global warming potential (GWP100-yr) of 23500 relative to CO2. The temperature dependence of the rate coefficient (kOH) for the OH + (CF3)2CFCN reaction is reported for the first time: kOH(278–358 ...

Although total UBA1 levels were unchanged, after oxidation for 60 min, we observed dramatic changes in the levels of BIAM-labeled UBA1 in both the membrane and cytosol fractions that suggested oxidative stress induces translocation of UBA1 from the cytosol to the membrane. Notably, in PrdxII−/− ...

The self-diffusion of parabens (methylparaben, propylparaben) and tetramethylsilane in the binary solvents carbon tetrachloride – co-solvent (methanol‑d4, acetone‑d6) has been investigated by the pulsed gradient spin-echo nuclear magnetic resonance (PGSE NMR) method in the range of temperatures...

The N-terminal fragment of Aβ (β = beta) peptide is able to bind essential transition metal ions like, copper, zinc and iron. Metal binding usually occurs via the imidazole nitrogens of the three His residues which play a key role in the coordination chemistry. Among all the investigated syste...

Retinoic acid-inducible gene I (RIG-I) detects viral RNAs and induces antiviral responses. During viral RNA recognition by RIG-I, tripartite motif protein 25 (TRIM25) plays a critical regulatory role by inducing K63-linked RIG-I polyubiquitination. Previous proteomics analysis revealed several p...

A comparison is reported between the products formed by the (n, α) reaction in hydrated and anhydrous sodium hexachloroiridate (IV), as well as in the ammonium salt. The effects of hydration and dehydration after the neutron irradiation are also described. The results show that both water of hy...

The adsorption and decomposition of trimethylamine on a Pt(111) surface have been investigated, using high resolution electron energy loss spectroscopy, Fourier transform infrared reflection—absorption spectroscopy and temperature-programmed desorption.Trimethylamine adsorbs molecularly at 85 K...

Organoelement derivatives with aluminium—aluminium, gallium—gallium and indium—indium bonds were synthesized for the first time in our group eight years ago. They show a remarkable and unprecedented chemical reactivity and up to now six different types of reaction have been found, which are s...

Growth of multifunctional nanohybrids with ordered porous structures is a much sought aspect for real time applications of mesoporous materials in detecting trace biomarkers in exhaled breathe. Here, we demonstrate the utilization of mesoporous silica (KIT-6) exhibiting 3-D porous structure as h...

Chemistry of indium phosphide clusters is studied using the powerful trapped ion cell techniques of Fourier transform ion cyclotron resonance (FTICR) mass spectrometry in conjunction with an external cluster source and ion guide. The external source is capable of generating a wide range of clust...

Equimolar reactions of tin (II) chloride, tin(IV) chloride or dimethyltin dichloride with macrocyclic Schiff bases lead to the formation of a new series of tin(II) and tin(IV) complexes. An attempt has been made to prove the structures of the resulting complexes on the basis of elemental analysi...

Variable-temperature 119Sn Mössbauer spectroscopic (VTMS) data for six tin phthalocyanine (pc) derivatives have been collected in order to ascertain the restrictions imposed by the macrocyclic ring on the vibrational motion of the tin atom. Thermal condensation of [(t-Bu)4pc]Sn(OH)2 yields the c...

Publisher SummaryThis chapter reviews the physical and inorganic chemistry of the phthalocyanines. It focuses on nuclear unsubstituted derivatives, except where mention of a substituted derivative is pertinent to the discussion. Phthalocyanine contained a ring system of four isoindole units link...
