Tris(1,10-phenanthroline-κ2 N,N′)iron(II) bis­[(1,10-phenanthroline-κ2 N,N′)tetra­kis­(thio­cyanato-κN)chromate(III)] acetonitrile tris­olvate monohydrate

Single crystals of the title heterometallic compound, [Fe(C12H8N2)3][Cr(NCS)4(C12H8N2)]2·3CH3CN·H2O or [Fe(Cphen)3][Cr(NCS)4(phen)]2·3CH3CN·H2O, were pre­pared using the one-pot open-air reaction of iron powder, Reineckes salt and 1,10-phenanthroline (phen) in acetonitrile. The asymetric unit consists of an [Fe(phen)3]2+ cation, two [Cr(phen)(NCS)4]− anions, three acetonitrile solvent mol­ecules and a water mol­ecule. The Fe and Cr atoms both show a slightly distorted octa­hedral FeN6 and CrN6 coordination geometry with adjacent angles in the range 79.67 (12)–95.21 (12)°. No classical hydrogen bonding involving the water molecule is observed

High energy hadrons in EAS at mountain altitude

An extensive simulation has been carried out to estimate the physical interpretation of dynamical factors such as , in terms of high energy interaction features, concentrated in the present analysis on the average transverse momentum. It appears that the large enhancement observed for versus primary energy, suggesting in earliest analysis a significant rise of with energy, is only the result of the limited resolution of the detectors and remains in agreement with a wide range of models used in simulations.Comment: 13 pages, 6 PostScript figures, LaTeX Subm. to JPhys

Hexa­kis­(dimethyl­formamide-κO)manganese(II) (dimethyl­formamide-κO)pentakis(­thio­cyanato­-κN)chromate(III)

The title compound, [Mn(C3H7NO)6][Cr(NCS)5(C3H7NO)], was obtained unintentionally as a product of an attempted synthesis of heterometallic complexes based on Reineckes anion using manganese powder, Reineckes salt and 1-(2-hy­droxy­eth­yl)tetra­zole as starting materials. The crystal structure of the complex consists of an [Mn(dmf)6]2+ cation and a [Cr(NCS)5(dmf)]2− anion (dmf = dimethyl­formamide). The MnII and CrIII atoms show a slightly distorted octa­hedral MnO6 and CrN5O coordination geometries with adjacent angles in the range 85.29 (13)–95.96 (14)°

Diammine(2,2′-bipyridine)­bis(thio­cyan­ato­-κN)cobalt(III) diamminetetra­kis(thio­cyanato­-κN)chromate(III) aceto­nitrile disolvate

The new heterometallic title complex, [Co(NCS)2(C10H8N2)(NH3)2][Cr(NCS)4(NH3)2]·2CH3CN, has been prepared using the open-air reaction of cobalt powder, Reineckes salt and 2,2′-bipyridine (dpy) in acetonitrile. The crystal structure consists of discrete cationic [Co(NCS)2(NH3)2(dpy)]+ and anionic [Cr(NCS)4(NH3)2]− building blocks, both with 2 symmetry, and acetonitrile solvent mol­ecules, which are linked together by N—H⋯N hydrogen bonds, forming extended supra­molecular chains. Furthermore, N—H⋯S, C—H⋯S and C—H⋯N hydrogen bonds inter­link neighbouring chains into a three-dimensional framework. The Co atom is in an elongated octa­hedral coordination environment with two N atoms from the dpy ligands and two NCS-groups in the equatorial plane and with two NH3 mol­ecules at the axial positions. The CrIII ion is octa­hedraly coordinated by two NH3 mol­ecules at the axial positions and four NCS-groups in the equatorial plane. Intensity statistics indicated non-merohedral twinning with the twin matrix [100; 00; 0]. The refined ratio of the twin components is 0.530 (1):0.470 (1)

Gel with Ectoine improves wound healing on a thermal burn model in rats

Due to the ability to create complexes of water molecules on the surface of the mucous membrane, ectoine is a promising compound for the treatment of burns. Evaluate the reparative activity of Ectoine using the thermal burn model in rats. In male rats (n=30), 2 thermal burns were counteracted under counter-anesthesia, one of which was treated by topical application of the test drugs for 7 days, and the other served as a contro

X-ray film chamber with carbon target of Tien-Shan complex array

X-ray films were exposed inside the ionization calorimeter under 74g/sq cm of carbon and 5 cm of lead. The X-ray film chamber area is 35 sq. m. Moving X-ray films were used, 50% of the events, which succeeded to determine incidence time, were identified with corresponding extensive air showers (EAS). For such events the size spectrum of associated EAS was derived. Two methods of energy measurement using X-ray films and ionization calorimeter were compared. The energy transfer from selected hadron to electromagnetic component is illustrated. It is found that in cascades with high energy release into electromagnetic components the hadron component is practically absent

IN VITRO EXPERIMENTAL REWIRING OF 4 NEUTROPHILIC GRANULOCYTE SUBSETS FROM THE PRO-INFLAMMATORY TO THE ANTI-INFLAMMATORY PHENOTYPE IN CHILDREN WITH SURGICAL PURULENT INFECTION OF SOFT TISSUE

Treatment of young children with atypical or recurrent purulent soft tissue infections (PSTD) that do not respond well to surgery and antibiotics is most challenging. PSTD occurs against the background of impaired functioning of the immune system and, first of all, the system of neutrophilic granulocytes (NG). The vector effect of immunotropic therapy on a specific NG subsets may allow the correction of NG dysfunctions without compromising host protection, including strategies to enhance, inhibit or restore their functions.The aim of study: to evaluate in vitro the modulating effects of arginyl-alpha-aspartyl-lysyl-valyl-tyrosyl-arginine (HP) on the transformed phenotype of 4 NG subsets, as well as on the functional activity of NG in children with purulent-inflammatory soft tissue diseases.We studied samples of peripheral blood (PB) from young children 2-4 years old: 17 children with atypical acute PSTD and 10 apparently healthy children. At stage I, a comparative assessment of the content and phenotype of 4 NG subsets CD16+CD62L+СD63- , CD16+CD62L+СD63+, СD64- CD16+CD32+CD11b+, СD64+CD16+CD32+CD11b+, phagocytic and microbicidal functions of NG was carried out. At stage II, the in vitro system determined the effects of HP on NG in children with PSTD according to the studied parameters. By the method of flow cytometry (FC500 “Beckman Coulter” (USA), conjugates of MkAT “Beckman Coulter International S.A.” (France)), the relative number of NGs of the studied subsets and the density of receptor expression (MFI) were determined. To assess the phagocytic function of NG a microbiological method was used to assess the completeness of phagocytosis with S. aureus (strain 209). The activity of NG NADPH oxidase was investigated in the NBT-spontaneous test (NBTsp.) and in the in vitro NBT-induced test (NBTind.). A comparative study of PB samples from conventionally healthy children and children with PSTD made it possible to identify various variants of transformation of the phenotype of the studied NG subsets, associated with defects in their functional activity. In the in vitro system the effects of HP were demonstrated, manifested by a decrease in the amount of CD16+CD62L+CD63+NG and an increase in CD16+CD62L+CD63- NG, modulation of the negatively altered phenotype of subsets CD64- CD32+CD16+CD11b+NG and CD64+CD32+CD16+CD11b+NG, aimed at restoring phagocytic function and maintaining the tension of NADPH oxidases.As a result of the study it was found the immunomodulatory effects of HP, which is manifested in the reorientation of NG from the pro-inflammatory phenotype to the anti-inflammatory one, which can be used in the future when creating personalized targeted immunotherapy aimed at correcting defective functioning NG in early children, suffering from PSTD
