It has beed showed that perivascular adipose tissue (PVAT) of human internal thoracic artery (ITA) releases adventitia/adipocyte-derived relaxing factor (ADRF). The precise mechanism of vasodilatatory effect of ADRF is still unknown. It was suggested that various potassium channels may be involved in the action of ADRF. The aim of this study was to assess the involvment of potassium channels in...

the hydrogenation characterizations of the hydrogen storage alloy mmni4.22co0.48mn0.15al0.15 (mm= mischmetal), and the effect of hydrogenation/dehydrogenation (h/d) cycling on its structural and morphological properties are investigated. the results indicate that after several h/d cycles the alloy was pulverized into fine particles, but it kept its hexagonal cacu5-type structure. the pressure-c...

In the structure of the title compound, [Mn(C(11)H(8)N(5)O)(N(3))](n), the Mn atoms are hexa-coordinated by five N atoms and one O atom. The coordination polyhedron of the Mn atom is a slightly distorted octa-hedron. The Mn atoms are connected by azide anions with a μ(2)-1,1 mode and by 5-(8-quinolyloxymeth-yl)tetra-zolate ligands in a μ(2)-η(1)(N),η(3)-(N,N,O) fashion to form a two-dimensional...

Manganese (Mn) plays an important role in the etiology of several neurobehavioral disorders, but there is a lack of data regarding its specific effects on neurotransduction, especially dopaminergic neurotransduction. We investigated the relationship between motor deficits and alterations in the expression of tyrosine hydroxylase (TH) and dopamine D2-like receptors (DR), including the three dopa...

A combined experimental and time-dependent density functional theory (TDDFT) investigation of the title reaction is presented. Both 'hot' and 'cold' laser-ablated Mn atom beams have been employed to determine the translational excitation functions for production of MnCl*(c(5)Σ(+), d(5)Π, e(5)Δ, e(5)Σ(+), A(7)Π). Analysis in terms of the multiple line-of-centres approach shows that the 'hot' res...

Ca(2+) is an integral component of the Mn(4)O(5)Ca cluster of the oxygen-evolving complex in photosystem II (PS II). Its removal leads to the loss of the water oxidizing functionality. The S(2)' state of the Ca(2+)-depleted cluster from spinach is examined by X- and Q-band EPR and (55)Mn electron nuclear double resonance (ENDOR) spectroscopy. Spectral simulations demonstrate that upon Ca(2+) re...

The study was aimed at investigating the effects of Bacillus velezensis LSG2-5 isolated from host’s intestinal tract on growth performance, immune response, antioxidant capacity, and disease resistance Amur minnow (Rhynchocypris lagowskii Dybowski). 535 fish were divided into 5 groups with 3 replicates per group. Diets containing different doses (0, 106, 107, 108, 109 CFU/g, respectively) B. us...

To understand the reaction mechanism between high Mn-high Al steel and slag, experiment of Fe-Mn-Al melts with CaO-SiO2-type flux was carried out in MgO crucible at 1873 K. The evolution morphology interface inspected firstly, then global kinetics modeled consideration effect dynamic interfacial phenomena. results show that Fe-5 mass % alloy SiO2 or low protective strong chemical affinity metal...

The authors regret a spelling mistake in the surname of one of authors. The surname given as ‘Vasilev’ should be ‘Vasiliev’. Furthermore a second affiliation for the author A. D. Vasiliev was inadvertently omitted. The correct spelling and affiliations of all the authors for this paper is as shown above. The Royal Society of Chemistry apologises for these errors and any consequent inconvenience...

The reactions o f M n(CF3COO)2 (1) with N,N,N',N'-tetramethylethylenediamine (tmen), 2,2'-bipyridine (bipy) and triethanolamine (tea) yield three new mononuclear coordination compounds: rra«5-[Mn(tmen)2(CF3COO)2] (2), cw-[Mn(bipy)2(C F3COO)2] (3), and [Mn(tea)2](CF3COO)2 (4). The X-ray structures o f the compounds 2, 3, and 4 are described. The seven-coordination o f the manganese(II) ion in 4,...
