Патриотическое воспитание молодежи на примере малой Родины
В статье поднята важнейшая тема - патриотическое воспитание подрастающего поколения России. Этот вопрос особенно актуален сейчас, учитывая то, что в современном обществе произошла переоценка значимости жизненных ценностей: материальное благополучие стало основным, духовно-нравственное стало вторичным. Авторы анализируют сложившуюся ситуацию, приводят успешные примеры работы с молодежью на примере Юргинского района. В статье даны рекомендации по возрождению патриотического воспитания, как на местном уровне, так и на уровне государства

Preparation and complex formation of lipophilic derivatives of 1,3,5-Triamino-1,3,5-trideoxy-cis-inositol
In dieser Arbeit wurden die Liganden 1,3,5-Tris{[(E)-(2-hydroxyphenyl)¬methyl¬iden]¬amino}-1,3,5-tridesoxy-cis-inosit (thici), all-cis-2,4,6-Trimethoxy-N1,N2,N3-tris(2-hydroxybenzyl)-1,3,5-cyclohexantriamin (thbca), 1,3,5-Tridesoxy-1,3,5-tris(2-hydroxybenzylamino)-cis-inosit (thci), all-cis-2,4,6-Trimethoxy-N1,N2,N3-tris[(E)-2-hydroxybenzyliden]-1,3,5-cyclohexantriamin (thbci), all-cis-2,4,6-Trimethoxy-N1,N3,N5-tris[(E)-(2-pyridylmethyliden)-1,3,5-cyclohexan-triamin (tpmci), all-cis-2,4,6-Trimethoxy-N1,N3,N5-tris(2-pyridylmethyl)-1,3,5-cyclohexan-triamin (tpmca) und 1,3,5-Tridesoxy-1,3,5-tris(2-pyridylmethyl¬amino)-cis-inosit (pmaci) synthetisiert und ihr koordinationschemisches Verhalten durch Röntgenstrukturanalysen, Potentiometrie, mittels ein- und zweidimensionaler NMR-Spektroskopie sowie durch Cyclovoltammetrie untersucht. Der Co(tpmca)Cl3-Komplex spaltet im basischen Milieu sukzessive alle drei Pyridylmethylsubstituenten ab. Zwischenstufen dieser Reaktion sind hydrolyseempfindliche Iminkomplexe, die durch oxidative Dehydrogenierung entstehen. Kondensationsreaktionen der Co(taci)- und Ni(taci)-1:1-Komplexe mit Pyridin-2-carbaldehyd führten zur Bildung der Komplexe Co(pmenci)(pic) und Ni(pmenci)(pic), die durch Röntgenstrukturanalysen nachgewiesen wurden. Die pKS-Werte und die Stabilitätskonstanten der Kupferkomplexe des Liganden all-cis-2,4,6-Trimethylcyclohexan-1,3,5-triamin (tmeca) wurden mittels potentiometrischer und NMR-Titration bestimmt.New lipophilic ligands derived from 1,3,5-Triamino-1,3,5-trideoxy-cis-inositol (taci), namely, 1,3,5-Trideoxy-1,3,5-tris(2-hydroxybenzylamino)-cis-inositol (thci), all-cis-2,4,6-Trimethoxy-N1,N2,N3-tris(2-hydroxybenzyl)-1,3,5-cyclohexane-triamine (thbca), 1,3,5-Tris{[(E)-(2-hydroxyphenyl)¬methyl¬iden]¬amino}-1,3,5-trideoxy-cis-inositol (thici), all-cis-2,4,6-Trimethoxy-N1,N3,N5-tris[(E)-(2-pyridylmethyliden)-1,3,5-cyclohexane-triamine (tpmci), all-cis-2,4,6-Trimethoxy-N1,N2,N3-tris[(E)-2-hydroxybenzyliden]-1,3,5-1,3,5-cyclohexane-triamine (thbci), all-cis-2,4,6-Trimethoxy-N1,N3,N5-tris(2-pyridylmethyl)-1,3,5-cyclohexane-triamine (tpmca) und 1,3,5-Trideoxy-1,3,5-tris(2-pyridylmethyl¬amino)-cis-inositol (pmaci) have been synthesized. The conformation equilibrium of thbca was studied in solution and a strong dependence on pH and temperature was found.
The complexing properties of the ligands towards Zn2+, Cd2+, Ga3+, Ni2+, Cu2+ and Co3+ have been investigated in solution and in solid state using NMR-spectroscopy, potentiometry, cyclic voltammetry and X-ray analysis. For the CoIII(tpmca)-complex, an oxidation of the ligand was observed in alkaline solution. Intramolecular condensation reactions between coordinated polyamino-polyalcohols and pyridine-2-carboxyaldehyde have been examined as part of a route to the synthesis of polydentate ligands and complexes. The pKA-values and the stability constants of all-cis-2,4,6-Trimethylcyclohexane-1,3,5-triamin (tmeca) with Cu2+ were measured with potentiometric and NMR-titration experiments

Qualitative Profiling of Polyglucose Degradation Products in Peritoneal Dialysis Fluids
Heat
sterilization of peritoneal dialysis (PD) fluids leads to
partial degradation of the osmotic agent to form reactive carbonyl
structures, which significantly reduce the biocompatibility of PD
fluids and impair long-term PD therapy. Hence, it is important to
know the exact composition of the degradation products to improve
biocompatibility of PD fluids. Our study conducted targeted screening
for degradation products in polyglucose (icodextrin)-containing PD
fluids (pGDPs) by applying <i>o</i>-phenylenediamine (OPD)
to form stable derivatives, which were analyzed by ultrahigh-performance
liquid chromatography with hyphenated diode array tandem mass spectrometry
(UHPLC–DAD–MS/MS). For the first time, specific degradation
products of polyglucose, namely, 4-deoxyglucosone (4-DG) and 3,4-dideoxypentosone
(3,4-DDPS), could be identified in PD fluids. Further, a reaction
product of 5-hydroxymethylfurfural (5-HMF) and OPD could be characterized
to be (5-(1<i>H</i>-benzo[<i>d</i>]imidazol-2-yl)furan-2-yl)methanol.
Additionally, 3-deoxyglucosone (3-DG) and 3-deoxygalactosone (3-DGal),
both known to be present in glucose-based PD fluids, were also detected
in polyglucose-containing fluids. Trapping a hitherto unknown degradation
product with OPD yielded 1,4-bis(1<i>H</i>-benzo[<i>d</i>]imidazol-2-yl)-3,4-dihydroxybutan-1-one, which was present
in heat- as well as filter-sterilized PD fluids
