Organic matter (straw (S) and manure (M)) has been widely applied to the black soil. This study aims to explore the effect of mean annual temperature on soil enzyme measurement in the cold region. According to the latitude in western Heilongjiang Province, China, 12 positioning test sites were selected with the application period of organic matter greater than five years. A mixed-effects model was established to analyze the relationship between mean annual temperature and soil enzyme activity that related to carbon (C), nitrogen (N), and phosphorus (P) acquisition. In addition, a systematic analysis was made to determine the relationship among the vector angle and vector length, soil nutrient, microbial biomass C:N ratio, and extracellular enzyme stoichiometry. The results show that the C acquisition enzyme activity of M and S treatment decreased, as the mean annual temperature increased, whereas, there was an increase in the N acquisition enzyme activity. There was a significant difference in the P acquisition enzyme activity of M and S treatment. The P acquisition enzyme activity decreased in the M treatment, as the mean annual temperature increased, whereas increased in the S treatment. Moreover, there was a negative correlation between the vector length and vector angle of soil extracellular enzymes. All soil samples were limited by microbial N, while some ones were limited by microbial C. In addition, the natural logarithmic ratio of NAG+LAP and BG+CBH was significantly negatively correlated in the M and S treatments. The combination of the Mantel test and the heat map showed that the soil C, N, and P acquisition enzyme activities were significantly correlated with the mean annual temperature. Redundancy analysis and hierarchical segmentation showed that the individual factors greater than 10% in the M treatment were the mean annual temperature, pH, and soil C:N ratio, accounting for 30.13%, 22.32%, and 12.27%, respectively. The extracellular enzyme N:P was positively correlated with the mean annual temperature and pH. The extracellular enzymes C: N and C:P were positively correlated with the soil C: N. The individual factors greater than 10% in the S treatment were pH, the application period of organic matter, C input, mean annual temperature, and soil C:P, accounting for 21.3%, 20.01%, 18.48%, 11.46%, and 11.31%, respectively. The extracellular enzyme C: N was positively correlated with pH, soil C:P, and mean annual temperature. The extracellular enzyme C:P was positively correlated with pH and soil C:P. The extracellular enzyme N:P was positively correlated with the C input, the application period of organic matter, and the mean annual temperature. In conclusion, the microbial N mainly limited the organic matter (straw and manure) application into black soil in the northeast cold region, according to the soil extracellular enzyme measurement and vector analysis. Both manure and straw application were driven by mean annual temperature, whereas the straw application was further influenced by carbon input and the application period. This finding can provide the data support and theoretical basis for the C, N, and P fertilization model for the black soil nutrient restoration in the cold region. [ABSTRACT FROM AUTHOR]

Mollisols (from Latin mollis, "soft") are the types of highly fertile soil with a thick layer of humus, high organic matter content, and strong nutrient capacity. The natural granary has played an indispensable role in the crucial agricultural and livestock production activities in many countries. A perfect tradeoff can be required for high crop yields with less nutrient loss in the soil under intensified farming practices. Among them, the organic matter greatly contributes to the high fertility, particularly at the medium to high latitudes in the cold and cool regions. Excessive depletion of organic matter can directly impact grain production in the sustainable development. An important approach to restoring organic carbon can be returning the organic materials to the soil via organic matter incorporation. Two common approaches are employed in conventional cultivation: straw incorporation and organic fertilizer application. However, there is an ongoing debate regarding which one is more beneficial for sequestering organic carbon. It is of significant importance to investigate the conditions under which straw incorporation or organic fertilizer application is more advantageous for carbon sequestration. Additionally, the organic matter incorporation is also dependent on various factors, such as fertilization duration and carbon input. The organic materials vary significantly in the decomposition with the increasing fertilization duration, leading to different effects on the soil organic carbon retention. Carbon input is one of the most important limiting factors in soil organic carbon sequestration and the carbonto-nitrogen ratio. Previous studies have focused mostly on controlled experiments to investigate the effects of different organic matter incorporation on soil organic carbon sequestration. Less attention was paid to the different fertilization durations and carbon inputs under organic matter incorporation. In this study, a meta-analysis approach was utilized to examine the impact of straw incorporation and organic fertilizer application on soil carbon sequestration under various fertilization durations and carbon inputs in Mollisols. A systematic search of peer-reviewed articles was conducted to apply the following criteria for reliability: 1) The experiments included both laboratory and field trials, consisting of control groups without fertilizer application, and experimental groups with either straw incorporation or organic fertilizer application; 2) The trials were performed on Mollisols to record the latitude, longitude, and climatic conditions of the experimental sites; 3) Relevant indicators of soil property with their means, standard deviations, and the number of replicates was directly extracted from the articles' text, tables, or figures. A total of 41 articles with 2012 observations were obtained after the screening process. The results indicated that the organic manure return was more effective in increasing the soil organic carbon content, compared with the straw return. There was a significant increase of 42.99% in soil organic carbon, 39.97% in total soil nitrogen, and 74.01% in total soil phosphorus in Mollisols. By contrast, the straw return resulted in a significant increase of 14.96% in soil organic carbon, 15.03% in total soil nitrogen, and 20.03% in total soil phosphorus. Moreover, the organic manure return was more effective than the straw return with the increase of treatment years, in terms of the soil organic carbon content. There were different effects of organic manure return to the field on the soil carbon sequestration under different carbon input conditions. The organic carbon sequestration of organic manure returning to the field can be significantly higher than that of straw under medium carbon input conditions. Some suggestions were proposed that the organic manure return under long-term medium carbon input was more beneficial to the increase of organic carbon sequestration. Overall, the findings can provide valuable insights for the scientific selection of organic materials in the field return in Mollisols. [ABSTRACT FROM AUTHOR]

A series of Na1+xSr4-2x (BO3)3 ∶xCe3+ phosphors which can be excited by ultraviolet light were prepared by high temperature solid phase method. The phase structure, morphology and luminescence characteristics of the samples were characterized and analyzed by X-ray diffraction, scanning electron microscopy and fluorescence spectrum. X-ray diffraction results show that Ce3+ is successfully doped into NaSr4(BO3)3. It is found that luminescence center of Ce3+ occupied Sr2+ (1) and Sr2+ (2) in NaSr4(BO3)3 by means of Gaussian peak fitting and contrastive analysis of multiple spectra. The effects of Ce3+ doping concentration on the luminescence location and luminescence intensity were studied. With the increase of Ce3+ doping concentration, the emission spectra show a red shift and the luminescence intensity shows a trend of enhancing→ weakening→re-enhancing. By comparing the emission spectra of phosphors with the absorption spectra of plant photosynthetic pigments, it is found that the phosphors can not only absorb 300 ~350 nm UV light, but also well cover the absorption band of blue light region required by plant photosynthetic pigments. This results show that the phosphor has potential value in agricultural production as a light conversion agent. [ABSTRACT FROM AUTHOR]

Objective To explore the effects of single injection of varying doses of pilocarpine on hippocampal injury in mice and to providea reference for creating the model of epilepsy. Methods A total of 100 healthy C57BL/6 mice were divided into the normal group and three treated groups with various doses of pilocarpine injection, namely 250 mg/kg, 290 mg/kg and 350 mg/kg. After that, the success rate and mortality were compared. The lesions of hippocampus were detected by immunohistochemical staining for the neurons and glial cells. The pathological changes of hippocampus were analyzed. Results In this series, 12% of mice could reach level 4(Racine scale) in 250 mg/kg group, and no mortality was found. In 290 mg/kg group, 70% of mice could get to the level 4, and the mortality was 32%. In the 350 mg/kg group, 86% of mice could reach level 4, and the mortality rate was 56%. Immunohistochemical staining results showed that the number of neurons in the hippocampus was significantly reduced compared with that in the normal group after injection of different concentrations of pilocarpine. Meanwhile, the number of microglia and astrocytes in the three groups was significantly higher than that in the normal group. However, there was no significant change in the number of activated microglia between the 250 mg/kg group and normal group, which was significantly increased in the other two groups. Conclusion The single injection of 290 mg/kg pilocarpine induced epilepsy model with high success rate, low mortality and obvious damage in hippocampus can be used as a reference method for creating the model of epilepsy.

Not only dose vitamin D play a principal role in the bone metabolism and calcium homeostasis, but also make an attributed additional effects to the immunomodulatory, anti-inflammatory, and the protection of neuroprotective capacity which indicates the vitamin D in autoimmune diseases like multiple sclerosis (MS). The data of the epidemiological and clinical have showed that the low level or metabolic disorder of VD could be a risk factor for multiple sclerosis. Another study has reported that the serum concentrations of VD and multiple sclerosis might be correlated to the activity and progress of disease. However, there is disagreement about the role of VD in the treatment and prevention of multiple sclerosis. It is suggested that the available data could not enough or even contradictory to draw a conclusion that the VD supplement existing as a treatment for MS measures of clinical intervention.
