The strong LAC4 promoter (P(LAC4)) from Kluyveromyces lactis has been extensively used to drive expression of heterologous proteins in this industrially important yeast. A drawback of this expression method is the serendipitous ability of P(LAC4) to promote gene expression in Escherichia coli. This can interfere with the process of assembling expression constructs in E. coli cells prior to thei...

Stepwise construction of a 1D heterotrimetallic coordination polymer containing all three group 10 metal ions via an ammineplatinum(ii) metalloligand with d-penicillamine is reported. This system showed a significant enhancement in heterogeneous catalytic activity for electrochemical hydrogen evolution by the stepwise introduction of PdII and NiII into the PtII metalloligand.

The pyridine-rich complex [NiII(LN2Py3)(MeCN)](ClO4)2 (1) acts as an efficient electro- and photocatalyst in the generation of H2 from water. Observed TONs reach 1050 for electrocatalysis and a remarkable 3500 for photocatalysis. Experimental and DFT data support the ligand-reduced [NiIL˙] as the catalytically active species, contrasting with the [CoIL] observed for cobalt catalysts.

Phase-resolved VLT spectroscopy of the bursting Low Mass X-ray Binaries 4U 1636536/V801 Ara and 4U 1735-444/V926 Sco is presented. Doppler images of the NIII λ4640 Bowen transition reveal compact spots which we attribute to fluorescent emission from the donor star and enable us to define a new set of spectroscopic ephemerides. We measure Kem = 277 ± 22 km s and Kem = 226 ± 22 km s from the NIII...

abstract herbicides are the main sources of soil and water pollution in paddy fields. herbicides mobility to the surface and ground water is a major concern for human health and the environment. it is, therefore, necessary to investigate their fate and their interactions in natural ecosystems. to meet this purpose, field experiments were conducted to measure kinetic of thiobencarb dissipation i...

A nickel(ii) complex [Ni2LR2(CH3CN)4](ClO4)2·2CH3CN (1) has been synthesized by using a tridentate reduced Schiff base ligand, HLR, 2-[(3-methylamino-propylamino)-methyl]-4-nitrophenol and Ni(ClO4)2·6H2O. Stoichiometrically controlled addition of NH4SCN to the acetonitrile-water solution of 1 produced two other complexes, [Ni2LR2(μ1,1-NCS)(CH3CN)2](ClO4)·CH3CN (2) and [Ni2LR2(NCS)2 (CH3CN)2] (3...

The pond turtle (Trachemys scripta elegans) exhibits a notably sluggish pupillary light reflex (PLR), with pupil constriction developing over several minutes following light onset. In the present study, we examined the dynamics of the efferent branch of the reflex in vitro using preparations consisting of either the isolated head or the enucleated eye. Stimulation of the oculomotor nerve (nIII)...
