Abstract:Ensuring food security, increasing farmers’ income and improving people’s living standards are the focus of attention of all countries in the world today. “Centrey Tianwang” biological organic fertilizer has been upgraded to multi-functional biological organic fertilizer innovation, accepted as a new invention patent. “Centrey Tianwang” multifunctional biological organic fertilizer is a long-term natural biological organic fertilizer with high concentration. It is a new kind of slow-release fertilizer, with both quick and long-term effects. It can both fully meet the nutrient requirements of the crop, and maintain water and fertilizer, improve soil and prevent disease. It can not only control agriculture pollution, improve the crop quality and promote the yield of various crops, but also have special effects on the improvement of saline-alkali land, restoration of polluted cultivated land and degradation of agricultural residues. It is a kind of slow-release, long-acting bio-organic fertilizer that does not need any other fertilizer to be used with field crops and does not need topdressing during the whole growing period of crops. “Centrey Tianwang” multi-functional bio-organic fertilizer collects the essences of various medicinal plants, natural minerals, nano organic compounds and aerospace microbial agents, through special process, refined and processed, non-toxic, harmless, without side effects.

Salinity is considered to be one of the most severe problems in worldwide agricultural production, but the published investigations give contradictory results of the effect of ionic and osmotic stresses on photosynthesis. In the present study, long-term effects of both ionic and osmotic stresses, especially on photosynthesis, were investigated using the moderately halotolerant cyanobacterium Synechocystis sp. PCC 6803. Our results show that the PSII activity and the photosynthetic capacity tolerated NaCl but a high concentration of sorbitol completely inhibited both activities. In line with these results, we show that the amount of the D1 protein of PSII was decreased under severe osmotic stress, whereas the levels of PsaA / B and NdhF3 proteins remained unchanged. However, high concentrations of sorbitol stress led to a drastic decrease of both psbA (encoding D1) and psaA (encoding PsaA) transcripts, suggesting that severe osmotic stress may abolish the tight coordination of transcription and translation normally present in bacteria, at least in the case of the psaA gene. Taken together, our results indicate that the osmotic stress component is more detrimental to photosynthesis than the ionic one and, furthermore, under osmotic stress, the D1 protein appears to be the target of this stress treatment.

Mineralization Processes

SummaryThe mineralization kinetics of nitrogen in acid soils, and their modification by the addition of an organic fertilizer (cattle slurry), were studied by incubating a humic cambisol for 36 weeks using a method based on that of Keeney & Bremner (1967). The cumulative curve of the quantity of nitrogen mineralized in soil not given fertilizer departs significantly from Stanford's theoretical model, which predicts linear dependence of nitrogen mineralized upon √t. The observed kinetics are interpreted as due to the superposition of two mineralization processes involving different substrates.The cumulative mineralized nitrogen curves for soil samples enriched with the various slurry fractions likewise reflect complex kinetics involving at least two main substrates. Consideration of the net mineralized nitrogen shows that F,, the solid fraction with the highest C/N ratio, clearly induced immobilization of nitrogen during the first 130 days of incubation, and analysis of the NO3/NH4 ratio suggests that this immobilization was probably at the expense of nitrate. F3, the liquid fraction, first induced a brief period of mineralization and then stabilized nitrogen levels, giving rise to a reduction in net mineralized nitrogen. The addition to the soil of F2, the semi-liquid fraction, produced results intermediate between those of the other two fractions.In conclusion, the increase in organic nitrogen in the soil after addition of cattle slurry depends in the short term on the liquid and semi-liquid fractions, whereas long-term effects involve both the stable residues of these fractions and the more solid fraction. The labile fraction of the pool of mineralizable N benefits more than the recalcitrant fraction, and the time constants of the mineralization process are reduced.

Children With Asthma

To evaluate the long-term effects of slow-release formulations of theophylline and terbutaline on pulmonary function, clinical symptoms, and side effects, 24 children with stable and moderately severe perennial asthma participated in a prospective double-blind crossover study. The patients and the treatments were randomized according to the Latin square design to eliminate all possible period/climate biases throughout the protracted study period. The treatments consisted of terbutaline, 5 mg, theophylline, 200 mg, the combination, and placebo, given twice daily orally and crossing over every 28 days. The two drugs, administered alone or in combination, improved lung function and symptoms when compared with placebo. The interaction of theophylline and terbutaline was quantitatively shown by 2 x 2 factorial statistical design to be essentially additive rather than synergistic in the control of asthma. No increase in side effects was noted when the combined therapy was used. These findings suggest therapeutic advantages to combining submaximal oral doses of sustained-release theophylline and terbutaline for the long-term treatment of children with asthma.

The long-term field experiment with new high yielding perennial energy crop - cup plant (Silphium perfoliatum L.) was conducted in order to evaluate its biomass productivity in Vėžaičiai branch of the Lithuanian Research Centre for Agricultural and Forestry. Experimental site – naturally acid Bathygleic Dystric Glossic Retisol, pH 4.2-4.4. Granulated sewage sludge was applied (at 45 and 90 t ha-1 rates) as an alternative organic fertilizer. The fertilization was done at the beginning of the experiment, prior to cup plant’s sprouts planting in 2013. Each experimental year, traditional N60P60K60 fertilization was performed in a separate treatment. Cup plant’s biomass was harvesting once per season at the end of vegetation. Cup plant’s dry mass (DM) yield substantially increased from 2.80 t ha-1 (in 2014) to 13.41 t ha-1 (in 2016). The use of sewage sludge fertilization was notably superior to that of mineral fertilization for cup plant’s biomass productivity. In all experimental years, the optimal was the application of 45 t ha-1 rate of sewage sludge - in compare with unfertilized treatment (control), DM yield increased by 66 %, on average. Increasing of sewage sludge rate up to 90 kg ha-1 did not give any DM yield supplement. Energy evaluation of growing technology revealed that the application of 45 t ha-1 sewage sludge rate caused the substantial increase of energy output from 1 ha; and on the contrarily, sharply decreased net energy ratio. In order to determine the long-term effects of fertilization on biomass yield, these studies will continue a few more years.

Preparation And Evaluation

Background: Oral mucositis is a common debilitating complication of cancer chemotherapy and radiotherapy that can reduce the quality of patient’s lives. Hence, treating this condition plays an important role in increasing the patient’s tolerance. Objectives: Doxepin mucoadhesive gel is useful for treating oral mucosa inflammation caused by long-term effects of chemotherapy, which has low adverse effects. Methods: Doxepin gel’s formulation was prepared with various concentrations of poloxamer 407 and hydroxypropyl methylcellulose in deionized water. The prepared gels were evaluated for pH, appearance, viscosity, spreadability, stability, and drug release. Results: After providing gels containing doxepin, formulations 1, 2, 8, and 9 had low quality and, thus, were removed from the study. Based on qualitative evaluations, formulations 3 and 4 did not meet the criteria for mucoadhesive gel and were removed from the study. The best formulation contained 17% w/w poloxamer 407, 10% w/w hydroxypropyl methylcellulose, and 5% w/w doxepin. Conclusions: Suitable physicochemical properties of prepared doxepin mucoadhesive gel enable it to well cover inflamed and damaged oral mucosa. On the other hand, doxepin’s slow release from formulation (8 hours) can increase therapeutic effects and reduce side effects, which can heal and soothe inflammations of the oral mucosa and be useful in cancer patient’s treatment.
