Opis:
Odmiana GAJ (PGR 294) została wyselekcjonowana z krzyżówki międzygatunkowej szwedzkiej odmiany Fiskeby V (Glycine max) z linią 11 (Glycine soja), którą wykonano w KGiHR AR Poznań w 1987 roku. Rośliny tej odmiany charakteryzowały się obfitym wzrostem i tworzeniem licznych pędów bocznych powodujących krzaczasty typ wzrostu. Rośliny odmiany GAJ osiągały wysokość 84 cm i zawiązywały najniższy strąk na poziomie 13,1 cm od powierzchni gleby w łanie o zagęszczeniu około 60 roślin na metrze kwadratowym. Rośliny odmiany GAJ były sztywne i odporne na wylęganie. Odmiana GAJ przewyższała pod względem plonu nasion i białka z hektara dotychczas zarejestrowane odmiany soi w Polsce. Szczególnie dobrze plonowała w lata bardzo ciepłe i suche, co wskazuje na jej odporność na suszę.
The GAJ (PGR 294) cultivar was selected out of interspecies cross between Swedish cultivar Fiskeby V (Glycine max.) and breeding line 11 (Glycine soja), carried out in 1987 by the Department of Plant Breeding and Genetics of Agricultural University in Poznań. Growth of the breeding line was lush and the plants developed many branches, giving bushy growth. Plants were 84 cm high, upright and resistant to lodging. The lowest pod was set on 13.1 cm level above soil surface at density of about 60 plants per square meter. Seed and protein yield of GAJ cultivar was significantly higher than that of other cultivars registered in Poland. GAJ yielded especially well in hot summers because of its resistance to dry weather.

Opis:
Celem pracy była ocena zmian właściwości tekstury nasion soi odmiany Polan i Legenda spowodowanych moczeniem. Nasiona soi poddawano obróbce polegającej na moczeniu w wodzie o temperaturze 20ºC przez 2 godziny, a następnie poddawano je badaniom wytrzymałościowym. W trakcie procesu moczenia następował spadek wartości twardości i żujności nasion soi. Zmiany twardości oraz żujności dla odmiany Polan opisano funkcją liniową. Z każdą minutą moczenia wartość twardości spadała średnio o 1,71 N, a żujności o 0,3 N. Zmiany wartości twardości oraz żujności dla odmiany Legenda opisano funkcją wykładniczą. Wyznaczone współczynniki równań wskazują na to, że z każdą minutą notowano 2-procentowy spadek twardości oraz 4-procentowy spadek żujności.
Changes in textural properties of Polan and Legenda cultivars of soybean seeds resulting from hydrothermal processing were analyzed. The seeds were subjected to treatment consisting of soaking them in water on 20ºC for 120 minutes and were taken out each time and were subjected to compression tests. During the process of soaking a decrease in the values of hardness and chewiness of soybean seeds occurs. Changes in hardness and chewiness of the Polan variety are described by means of the linear function. For every minute the values of hardness dropped by 1.71 N on the average, and of chewiness by 0.3 N. Changes in hardness and chewiness of the seeds Legenda variety were described by means of the exponential function. The coefficients of equations determined here suggest that for every minute there is a 2% reduction in hardness and a 4% reduction in chewiness.

Staphylococcus aureus is responsible for many types of infections related to biofilm presence. As the early diagnostics remains the best option for prevention of biofilm infections, the aim of the work presented was to search for differences in metabolite patterns of S. aureus ATCC6538 biofilm vs. free-swimming S. aureus planktonic forms. For this purpose, Nuclear Magnetic Resonance (NMR) spectroscopy was applied. Data obtained were supported by means of Scanning Electron Microscopy, quantitative cultures and X-ray computed microtomography. Metabolic trends accompanying S. aureus biofilm formation were found using Principal Component Analysis (PCA). Levels of isoleucine, alanine and 2,3-butanediol were significantly higher in biofilm than in planktonic forms, whereas level of osmoprotectant glycine-betaine was significantly higher in planktonic forms of S. aureus. Results obtained may find future application in clinical diagnostics of S. aureus biofilm-related infections.

Opis:
The glycine receptor belongs to the ligand-gated ion channel superfamily. It is a chloride conducting channel composed of four transmembrane domains. It was previously shown that the second transmembrane domain (M2) of the glycine receptor forms an ion conduction pathway throught lipid bilayers. The amino-acid sequence of the transmembrane segment M2 of the glycine receptor has a high homology to all receptors of the ligand-gated ion channel superfamily. In our report, we have used a synthetic M2 peptide. It was incorporated into a planar membrane of known lipid composition and currents induced by M2 were measured by the Black Lipid Membrane technique. When the planar lipid bilayer was composed of 75% phosphatidylethanolamine and 25% phosphatidylserine, the reversal potential measured in a 150/600 mM KCl (cis/trans) gradient was -19 mV suggesting that the examined pore was preferential to anions, PK/PCl = 0.25. In contrast, when 75% phosphatidylserine and 25% phosphatidylethanolamine was used, the reversal potential was +20 mV and the pore was preferential to cations, PK/PCl = 4.36. Single-channel currents were recorded with two predominant amplitudes corresponding to the main-conductance and sub-conductance states. Both conductance states (about 12 pS and 30 pS) were measured in a symmetric solution of 50 mM KCl. The observed single-channel properties suggest that the selectivity and conductance of the pore formed by the M2 peptide of the glycine receptor depend on the lipid composition of the planar bilayer.

A reversible effect of pH on the ionization of amino-acid residues at the active center of choline oxidase was observed near the optimum pH (8). Inactivation of choline oxidase took place in the pH ranges 3-6 and 9-11, in which irreversible changes in the structure occur leading to the enzyme inactivation. The first order rate constants of the enzyme's inactivation at various pH values were estimated for the irreversible changes. The Arrhenius analysis revealed no significant changes in the activation enthalpy, while an increase in the activation entropy reflected an increase in the conformational freedom.

Metal ions can modify plant metabolism and change the level of biologically active components. In the present study, the impact of short-term exposure to strontium on the accumulation of the metal as well as the content of isoflavones in soybean sprouts was investigated. The seeds were germinated in hydroponics with 0, 1, 1.5, 2.5, 5.0, or 10.0 mM of Sr for 72 hours. The content of strontium was assessed using flame atomic absorption spectrometry and the amount of isoflavones was determined with high performance liquid chromatography. dose-dependent accumulation of Sr and a linear correlation between the Sr concentration in the growth medium and the content of the element in the plant samples were observed. The largest changes in the isoflavone content, compared to the control, were noted in soy sprouts germinated in the presence of 5 and 10 mM of strontium. daidzin, genistin, malonyldaidzin, and malonylgenistin were the dominant isoflavones and their content increased by approx. 28, 44, 34, and 47%, respectively, compared to the control. low amounts of aglycones were found; moreover, their content decreased by ca. 19–30%. Our research can be important for obtaining a natural product enhanced with strontium and isoflavones, which contribute to prevention of osteoporosis associated with endog- enous oestrogen deficits

Opis:
It is demonstrated that amino acids such as glycine, betaine, and lysine may be applied as selective copper leaching agents in the process of hydrochemical oxidation of chalcopyrite at atmospheric pressure and in the temperature range 25÷65 °C. The advantage of the proposed method is its relative environmental friendliness. Solid samples of the initial mineral and leached chalcopyrite residues were analyzed by X-ray diffraction analysis, and Mössbauer and Raman spectroscopy. The results of the atomic absorption analysis showed that copper's extraction efficiency increased when the experiment's duration was raised and when the process temperature was higher. The leaching ability of amino acids was evaluated by the specific leaching rate of chalcopyrite in these reagents. Amino acid leaching was thought to be mainly due to the complexation of copper (II) glycinates, copper (II) betainates and copper (II) lysinates. This reaction can be enhanced by adding hydrogen peroxide to the system as an oxidant. It was determined that glycine was more effective as a leaching agent than betaine and lysine. Based on experimental data, it was assumed that the most possible mechanism is selective copper leaching due to the formation of chalcopyrite-based solid solution Cu1-XFeS2.

The aim of the paper was to present the possibility of applying the novel method (RP-HPLC ion pair method) for the simultaneous dissolution determination of combined tablet dosage form containing acetylsalicylic acid and glycine in pharmaceutical industry. The samples were gradient eluted using a Pursuit XS Ultra C18 column (150x3.0 mm, with a particle size of 2.8µm) with variable composition of mobile phase A (1-heptanesulfonic acid sodium salt aqueous solution (2.8 g/L), pH 2.2 ± 0.05 adjusted with orthophosphoric acid) and phase B (methanol). The detection was carried out at 210 nm with a consist flow rate of 0.4 mL min−1. The method was validated by determining precision (repeatability and intermediate precision), accuracy, specificity, linearity, range, system suitability, robustness and stability in accordance with ICH guidelines. The method was accurate, precise and linear within the range of 0.03 – 0.18 mg mL−1 for acetylsalicylic acid and 0.016 – 0.096 mg mL−1 for glycine. The method is simple, convenient and suitable for analyzing acetylsalicylic acid and glycine in pharmaceutical formulations. The method could also be used for routine assay determination after small modification of sample preparation.

Opis:
Among the methods applied to ensure optimal pharmaceutical availability of a drug is the incorporation of solid dispersions, i.e. combinations containing a therapeutic substance and a carrier deprived of its pharmacological activity. While manufacturing solid dispersions, special attention must be paid to carriers with a polymeric structure and hydrophilic properties, e.g. polyvinylpyrrolidone (PVP) and also phosphatidylcholine (PC). The aim of this study has been to evaluate the influence of the carriers PVP and PC 45 on pharmacokinetic parameters of Mg2+ absorption from Mg(Lev)2, Mg(LevGly), Mg(LevArg) as well as from solid dispersions containing these salts. The o/w partition coefficient was determined and the log P value calculated for pure salts and for solid dispersions containing the salts during this study. The process of Mg2+ absorption was examined in vitro on a model of the rat’s small intestine. Our analysis of the results indicates that addition of PVP or PC 45 to solid dispersions (containing magnesium levulinate salts) significantly improves the degree of Mg2+ ion absorption. It has been found that addition of PVP and PC 45 to solid dispersions with magnesium levulinate salts significantly influences the rate of Mg2+ absorption from the formulations. Moreover, the results indicate that additional ligand (glycine or arginine) in the structure of magnesium levulinate triggers the effect consisting in depressed lipophilicity for these compounds. Using the PVP or PC 45 carriers for making solid dispersions containing magnesium levulinate and derivatives with glycine or arginine ligands is quite a promising solution for attaining improved pharmaceutical availability of drugs.
Jedną z metod osiągnięcia optymalnej dostępności farmaceutycznej leku jest zastosowanie stałych rozproszeń, układów zawierających substancję leczniczą i nośnik, który jest pozbawiony własnego działania farmakologicznego. Przy wytwarzaniu stałych rozproszeń na szczególną uwagę zasługują nośniki o budowie polimerowej i właściwościach hydrofilowych. Należą do nich m.in. poliwinylopirolidon (PVP), a także fosfatydylocholina. Celem badań była ocena wpływu wybranych nośników: poliwinylopirolidonu (PVP) i roztworu fosfatydylocholiny (PC 45) na poprawę parametrów farmakokinetycznych procesu wchłaniania jonów Mg2+ z soli lewulinianu magnezowego Mg(Lev)2, Mg(LevGly), Mg(LevArg) oraz ze stałych rozproszeń zawierających te sole. W badaniach wyznaczono współczynnik podziału o/w i wyliczono wartość log P dla czystych soli oraz dla stałych rozproszeń zawierających te sole. Badania procesu wchłaniania jonów Mg2+ przeprowadzono metodą in vitro na modelu jelita cienkiego szczura. Wykazano, że dodatek PVP lub PC 45 do stałych rozproszeń zawierających sole lewulinianu magnezowego znacząco wpływa na poprawę stopnia wchłaniania. Na podstawie tych badań stwierdzono, że dodatek PVP lub PC 45 do stałych rozproszeń z solami lewulinianu magnezowego istotnie (p=0.01) wpływa na szybkość procesu wchłaniania jonów Mg2+ z otrzymanych formulacji. Ponadto wyniki badań wskazują, że dodatkowy ligand (glicyna, arginina) w strukturze cząsteczki lewulinianu magnezowego wywołuje efekt zmniejszenia lipofilowości dla tych związków. Zastosowanie nośników PVP lub PC 45 do wytwarzania stałych rozproszeń zawierających lewulinian magnezowy i pochodne z ligandami glicyny lub argininy jest obiecujące w poprawie dostępności farmaceutycznej.

Opis:
Two experiments were conducted during 2010 and 2011 main cropping seasons under different farmer fields at Pawe District of Northwestern Ethiopia in order to evaluate different commercially produced microbial inoculants, referred to as commercial rhizobial strains, on soybean yield. The first experiment was conducted with the aim of evaluating four commercial rhizobial strains (Legume fix, TSBF-531, TSBF-442 and MAR-1495) on soybean yield, while the second experiment conducted with the aim of evaluating and selecting the best rhizobial strain from the two rhizobial strains (Legume fix and MAR-1495). Non-inoculated soybean with and without the recommended rate (RR) of nitrogen (N) fertilizer treatments also included in the experiments. Treatments were arranged in a single replicate per field. Recommended rate of phosphorous (P) fertilizer was applied uniformly to all treatments. The two experiments analysis of variance indicated that there was significant difference (P < 0.05) among treatments in number of nodules, nodule weight, biomass yield and grain yield of soybean. Accordingly, the first experiment result indicated that the highest number of nodules, nodule weight, biomass yield and grain yield were recorded by using rhizobial strains of legume fix and MAR-1495. The second experiment result revealed that rhizobial strain MAR-1495 resulted consistent and highest number of nodules, nodule weight, biomass yield and grain yield of soybean. The increment in grain yield over the un-inoculated control, legume fix and full RR of N fertilized treatments recorded by MAR-1495 was 25.5, 9.7 and 9.9%, respectively. Moreover, inoculation of soybean seeds with rhizobial strain MAR-1495 also resulted to higher protein content in soybean plant tissue. Therefore, this study recommends use of the most suitable commercial rhizobial strain MAR-1495 for the study area to inoculate seeds before sowing for the production of soybean crop.

Opis:
Soybean (Glycine max (L.) Merrill) is an exotic crop to Ethiopia. Hence, inoculation with effective Bradyrhizobia spp. is crucial to improve its productivity. This study was therefore conducted in West Gojam Zone of Amhara Region in 2015 and 2016 aimed at evaluating the effect of bradyrhizobia strains (MAR-1495, SB-12 and TAL-379) with and without phosphorus fertilizer (23 kg P2O5 ha-1) on root nodulation and yield of soybean, and on residual soil nitrogen. The treatments were laid in randomized complete block design including a satellite control treatment with three replications. Effect of the use of rhizobia strains and P fertilizer on nodulation, yield and yield components of soybean was found statistically significant (P<0.05). The highest grain and dry matter yields of 2.7 and 6.4 t ha-1, respectively, were obtained from MAR-1495+P which was statistically at par with the yields obtained from MAR-1495 alone. A grain yield advantage of 30.8% over the control treatment was found from the use of MAR-1495 alone. Similarly, the maximum number of effective nodules (14.9) per plant was recorded from MAR-1495+P which was statistically at par with the number of effective nodules (11.6) per plant counted from MAR-1495 inoculated treatment. The highest residual soil N exceeding the control treatment by 0.029% (0.29 g total N per kg soil) was obtained from MAR-1495 alone. Therefore, inoculation with the strain MAR-1495 was found the most effective for improved soybean production in the study district and similar agroecologies.

Opis:
Hydrate complexes of magnesium aspartate, magnesium aspartate glycinate, magnesium aspartate arginate have been synthesized and characterized by the elemental and spectral analysis. The formulae of the magnesium complexes were Mg(C4H6O4N) • 4H2O, Mg(C6H10O5N2) • 5H2O, and Mg(C10H19O5N5) • 7H2O. The main thermal process: dehydration of the complexes, was studied using the thermoanalytical methods: differential thermal analysis (DTA), thermogravimetric analysis (TG), and differential scanning calorimemtry (DSC) measurements. The influence of additional ligands (glycinate or arginate) introduced to the structure of magnesium aspartate on the physicochemical properties of the newly synthesized compounds was analysed.
Metodą analizy elementarnej i spektralnej scharakteryzowano syntezowane hydraty kompleksów asparaginianu magnezowego, glicynianoasparaginianu magnezowego, arginiano-asparaginianu magnezowego, Kompleksy magnezowe o wzorach : Mg(C4H6O4N) • 4H2O, Mg(C6H10O5N2) • 5H2O, and Mg(C10H19O5N5) • 7H2O. Zastosowano metody termoanalityczne: różnicową termiczną analizę (DTA), termograwimetryczną analizę (TG), skaningową kalorymetrię różnicową (DSC) do badania głównego procesu termicznego: dehydratacji badanych kompleksów. Potwierdzono wpływ wprowadzonych do struktury asparaginianu magnezowego dodatkowych ligandów glicyny lub argininy na fizykochemiczne właściwości nowo syntezowanych związków.
