Effect of Different Vegetation Types on the Rhizosphere Soil Microbial Community Structure in the Loess Plateau of China

The Loess Plateau in China is one of the most eroded areas in the world. Accordingly, vegetation restoration has been implemented in this area over the past two decades to remedy the soil degradation problem. Understanding the microbial community structure is essential for the sustainability of ecosystems and for the reclamation of degraded arable land. This study aimed to determine the effect of different vegetation types on microbial processes and community structure in rhizosphere soils in the Loess Plateau. The six vegetation types were as follows:two natural grassland (Artemisia capillaries and Heteropappus altaicus), two artificial grassland (Astragalus adsurgens and Panicum virgatum), and two artificial shrubland (Caragana korshinskii and Hippophae rhamnoides) species. The microbial community structure and functional diversity were examined by analyzing the phospholipid fatty acids (PLFAs) and community-level physiological profiles. The results showed that rhizosphere soil sampled from the H. altaicus and A. capillaries plots had the highest values of microbial biomass C, average well color development of carbon resources, Gram-negative (G~-) bacterial PLFA, bacterial PLFA, total PLFA, Shannon richness, and Shannon evenness, as well as the lowest metabolic quotient. Soil sampled from the H. rhamnoides plots had the highest metabolic quotient and Gram-positive (G~+) bacterial PLFA, and soil sampled from the A. adsurgens and A. capillaries plots had the highest fungal PLFA and fungal:bacterial PLFA ratio. Correlation analysis indicated a signiifcant positive relationship among the microbial biomass C, G~- bacterial PLFA, bacterial PLFA, and total PLFA. In conclusion, plant species under arid climatic conditions signiifcantly affected the microbial community structure in rhizosphere soil. Among the studied plants, natural grassland species generated the most favorable microbial conditions.
Evaluation of Physicochemical, Microbiological and Sensory Stability of Frozen Stored Vacuum-Packed Lamb Meat

Nowadays, lamb meat represents only 7% of all meat produced in the world. In recent years the demand for standardized lamb meat cuts has been considered of great importance and the marketing occurs predominantly in the form of frozen cuts. Herewith, the main of this work was to evaluate the stability and safety of lamb meat during frozen storage. Meats were vacuum packed in high barrier multilayer plastic iflms and stored during 12 mon at (-18±1)oC. The meat stability was assessed by physical and chemical (lipid oxidation, objective color, pH value, cooking losses and instrumental texture), microbiological (total count of psychrotrophic, coliform count at 45°C, coagulase-positive staphylococci and the presence of Salmonella) and sensory analysis (acceptance test and visual evaluation). The vacuum packed lamb meat remained stable as to most physical and chemical indexes. Microbiological indexes showed good stability throughout the storage period according to Brazilian legislation standards to pathogenic microorganisms. Although a signiifcant reduction in tenderness (shear force increase from 3 to 8 kg), it showed a good sensorial acceptance for all attributes tested, including texture, with scores of around 7 (like moderately) during the 12 mon of storage. Therefore, it can be concluded that, under the conditions applied in this study, lamb meat presents a shelf life of at least 12 mon when stored at-18°C.
Soil pH Dynamics and Nitrogen Transformations Under Long-Term Chemical Fertilization in Four Typical Chinese Croplands

Long-term fertilization experiment provides the platform for understanding the proton budgets in nitrogen transformations of agricultural ecosystems. We analyzed the historical (1990-2005) observations on four agricultural long-term experiments in China (Changping, Chongqing, Gongzhuling and Qiyang) under four different fertilizations, i.e., no-fertilizer (control), sole chemical nitrogen fertilizer (F_N), sole chemical phosphorous and potassium fertilizers (F_(PK)) and chemical nitrogen, phosphorous and potassium fertilizers (F_(NPK)). The significant decline in topsoil pH was caused not only by chemical N fertilization (0.29 and 0.89△pH at Gongzhuling and Qiyang, respectively) but also by chemical PK fertilization (0.59△pH at Gongzhuling). The enhancement of available nutrients in the topsoil due to long-term direct nutrients supply with chemical fertilizers was in the descending order of available P (168-599%)>available K (16-189%)>available N (9-33%). The relative rate of soil pH decline was lower under long-term judicious chemical fertilization (-0.036-0.034 △pH yr~(-1)) than that under long-term sole N or PK fertilization (0.016-0.086 △pH yr~(-1)). Long-term judicious chemical fertilization with N, P and K elements decreases the nutritional limitation to normal crop growth, under which more N output was distributed in biomass removal rather than the loss via nitrate leaching. We concluded that the N distribution percentage of nitrate leaching to biomass removal might be a suitable indicator to the sensitivity of agricultural ecosystems to acid inputs.
Influence of B source materials on the synthesis of TiB_2-Al_2O_3 nanocomposite powders by mechanical alloying

An Al_2O_3-TiB_2 nanocomposite was successfully synthesized by ball milling of Al, TiO_2 and two B source materials of B_2O_3 (system (1)) and H_3BO_3 (system (2)). Phase identification of the milled samples was examined by X-ray diff raction. The morphology and microstructure of the milled powders were monitored by scanning electron microscopy and transmission electron microscopy. It was found that the formation of this composite was completed after 15 and 30 h of milling time in systems (1) and (2), respectively. More milling energy was required for the formation of this composite in system (2) due to the lubricant properties of H_3BO_3 and also its decomposition to HBO_2 and B_2O_3 during milling. On the basis of X-ray diff raction patterns and thermodynamic calculations, this composite was formed by highly exothermic mechanically induced self-sustaining reactions (MSR) in both systems. The MSR mode took place around 9 h and 25 h of milling in systems (1) and (2), respectively. At the end of milling (15 h for system (1) and 30 h for system (2)) the grain size of about 35-50 nm was obtained in both systems.
miR-133 links to energy balance through targeting Prdm16

Adipose (fat) tissues contain white, brown, and beige adipocytes. White adipocytes store extra energy in the form of lipids; ectopic and excessive accumulation of white adipose in the body leads to overweight and obesity, which often causes insulin resistance and Type 2 diabetes. Brown adipocytes, in contrast, contain hundreds of mitochondria per cell, dissipate energy into heat, and are negatively correlated to body weight and insulin resistance (Wu et al., 2013). Under cold temperature or β-adrenergic drug stimulation, a population of ‘beige’ or ‘brite’ adipocytes can be formed in the subcutaneous white adipose, containing intermediate levels of mitochondria and consume energy (Wu et al., 2013; Ye et al., 2013). Both brown and beige adipocytes are considered as good fats; and expansion or activation of these types of adipocytes thus represents a novel therapeutic strategy against obesity and diabetes.
Transient receptor potential channel A1 involved in calcitonin gene-related peptide release in neurons

Transient receptor potential channel A1 is one of the important transducers of noxious stimuli in the primary afferents, which may contribute to generation of neurogenic inflammation and hyperalgesia. The present study was designed to investigate if activation of transient receptor potential channel A1 may induce calcitonin gene-related peptide release from the primary afferent neurons. We found that application of al yl isothiocyanate, a transient receptor potential channel A1 activator, caused calcitonin gene-related peptide release from the cultured rat dorsal root ganglion neurons. Knock-down of transient receptor potential channel A1 with an antisense oligodeoxynucleotide prevented calcitonin gene-related peptide release by al yl isothiocyanate application in cultured dorsal root ganglion neurons. Thus, we concluded that transient receptor potential channel A1 activation caused calcitonin gene-related peptide release in sensory neurons.

Ketanserin improves cardiac performance after myocardial infarction in spontaneously hypertensive rats partially through restoration of baroreflex function

Aim: Baroreflex dysfunction is associated with a higher rate of sudden death after myocardial infarction (MI). Ketanserin enhances baroreflex function in rats. The present work was designed to examine whether ketanserin improves the post-MI cardiac function and to explore the possible mechanism involved. Methods: Spontaneously hypertensive rats (SHR) were treated with ketanserin (0.3 mg?kg~(?1_?d~(?1)). Two weeks later, blood pressure and baroreflex function were measured, followed by a ligation of the left coronary artery. The expressions of vesicular acetylcholine transporter (VAChT) and α7 nicotinic acetylcholine receptor (α7-nAChR) in ischemic myocardium, angiogenesis, cardiac function, and left ventricular (LV) remodeling were evaluated subsequently. Results: Ketanserin significantly improved baroreflex sensitivity (0.62±0.21 vs 0.34±0.12 ms/mmHg, P<0.01) and vagal tonic activity (heart rate changes in response to atropine, 54.8±16.2 vs 37.6±13.4 bpm, P<0.01) without affecting the blood pressure or basic heart rate in SHR. Treatment of SHR with ketanserin prominently improved cardiac function and alleviated LV remodeling, as reflected by increases in the ejection fraction, fractional shortening, and LV systolic pressure as well as decreases in LV internal diameter and LV relative weight. The capillary density, vascular endothelial growth factor expression, and blood flow in the ischemic myocardium were significantly higher in the ketanserin-treated group. In addition, ketanserin markedly increased the expression of VAChT and α7-nAChR in ischemic myocardium. Conclusion: Ketanserin improved post-MI cardiac function and angiogenesis in ischemic myocardium. The findings provide a mechanistic basis for restoring baroreflex function using ketanserin in the treatment of MI.

Deep Desulfurization of Diesel Fuels with Plasma/Air as Oxidizing Medium, Diperiodatocuprate (III) as Catalyzer and Ionic Liquid as Extraction Solvent

In this paper, the oxidative desulfurization (ODS) system is directly applied to deal with the catalytic oxidation of sulfur compounds of sulfur-containing model oil by dielectric barrier discharge (DBD) plasma in the presence of air plus an extraction step with the oxidation-treated fuel put over ionic liquid [BMIM]FeCl 4 (1-butyl-3-methylimidazolium tetrachloroferrate). This new system exhibited an excellent desulfurization effect. The sulfur content of DBT in diesel oil decreased from 200 ppm to 4.92 ppm (S removal rate up to 97.5%) under the following optimal reaction conditions: air flow rate (v) of 60 mL/min, amplitude of applied voltage (U) on DBD of 16 kV, input frequency (f) of 79 kHz, catalyst amount (ω) of 1.25 wt%, reaction time (t) of 10 min. Moreover, a high desulfurization rate was obtained during oxidation of benzothiophene (BT) or 4,6-DMDBT (4,6-dimethyl-dibenzothiophene) under the aforementioned conditions. The oxidation reactivity of different S compounds was decreased in the order of DBT, 4,6-DMDBT and BT. The remarkable advantage of the novel ODS system is that the desulfurization condition applies in the presence of air at ambient conditions without peroxides, aqueous solvent or biphasic oil-aqueous solution system.

A Sand Control and Development Model in Sandy Land Based on Mixed Experiments of Arsenic Sandstone and Sand: A Case Study in Mu Us Sandy Land in China

Serious desertification caused by human activity and climate change,in addition to water loss and soil erosion related to arsenic sandstone in the Mu Us Sandy Land,lead to severe scarcity of soil and water resources,which causes worse local agricultural conditions accordingly.Many physical properties of arsenic sandstone is complementary with that of sand,arsenic sandstone is therefore supposed to be blended to enhance water productivity and arability of sandy land.Container experiments are carried out to study the enhancement of water holding capacity of the mixture,the blending ratio of arsenic sandstone and sand,and the proper size of the arsenic sandstone particles,respectively.The results of the experiments show that particle size of 4 cm with a ratio of 1∶2 between arsenic sandstone and sand are the proper parameters on blending.Both water content and fertility increase after blending.Water use efficiency in the mixture is 2.7 times higher than that in sand by the water release curves from experiments.Therefore,a new sand control and development model,including arsenic sandstone blending with sand,efficient water irrigation management and reasonable farming system,is put forward to control and develop sandy land so that water-saving agriculture could be developed.Demonstration of potato planting about 153.1 ha in area in the Mu Us Sandy Land in China indicates that water consumption is 3018 m~3/ha in the whole growth period.It means that about 61%of irrigation water can be saved compared with water use in coarse sand without treatment.Recycle economic mode and positive feedback of sand resource-crop planting-soil resource are constructed,which changes sand into arable soil and make it possible to develop water-saving agriculture on it.The proposed model will be helpful for soil-water resources utilization and management in the Mu Us Sandy Land.
Labile Organic Matter Content and Distribution as Affected by Six-year Soil Amendments to Eroded Chinese Mollisols

Labile organic carbon(LOC)is a fraction of soil organic carbon(SOC)with rapid turnover time and is affected by soil fertilization.This investigation characterized the SOC content,LOC content and LOC distribution in the treatment plots of surface soil erosion at five levels(0-,5-,10-,20-and 30-cm erosion).The soil had received contrasting fertilizer treatments(i.e.,chemical fertilizer or chemical fertilizer+manure)for 6 years.This study demonstrated that both SOC and various LOC fractions contents were higher in the plots with fertilizer+manure than in those with fertilizer alone under the same erosion conditions.The SOC and LOC contents decreased as the erosion depth increased.Light fraction organic carbon,particulate organic carbon,easily oxidizable organic carbon(KMnO_4-oxydizable organic carbon),and microbial biomass carbon were 27%–57%,37%–47%,20%–25%,and 29%–33%higher respectively in the fertilizer+manure plots,than in the fertilizer alone plots.Positive correlations(p<0.05)between SOC content and different fractions contents were observed in all plots except the correlation between total SOC content and water-soluble organic carbon content in the different fertilization treatments.Obviously,fertilizer+manure treatments would be conducive to the accumulation of LOC and SOC in the Black soil of Northeast China.
Assimilating ASAR Data for Estimating Soil Moisture Profile Using an Ensemble Kalman Filter

Active microwave remote sensing data were used to calculate the near-surface soil moisture in the vegetated areas. In this study, Advanced Synthetic Aperture Radar (ASAR) observations of surface soil moisture content were used in a data assimilation framework to improve the estimation of the soil moisture profile at the middle reaches of the Heihe River Basin, Northwest China. A one-dimensional soil moisture assimilation system based on the ensemble Kalman filter (EnKF), the forward radiative transfer model, crop model, and the Distributed Hydrology-Soil-Vegetation Model (DHSVM) was developed. The crop model, as a semi-empirical model, was used to estimate the surface backscattering of vegetated areas. The DHSVM is a distributed hydrology-vegetation model that explicitly represents the effects of topography and vegetation on water fluxes through the landscape. Numerical experiments were conducted to assimilate the ASAR data into the DHSVM and in situ soil moisture at the middle reaches of the Heihe River Basin from June 20 to July 15, 2008. The results indicated that EnKF is effective for assimilating ASAR observations into the hydrological model. Compared with the simulation and in situ observations, the assimilated results were significantly improved in the surface layer and root layer, and the soil moisture varied slightly in the deep layer. Additionally, EnKF is an efficient approach to handle the strongly nonlinear problem which is practical and effective for soil moisture estimation by assimilation of remote sensing data. Moreover, to improve the assimilation results, further studies on obtaining more reliable forcing data and model parameters and increasing the efficiency and accuracy of the remote sensing observations are needed, also improving estimation accuracy of model operator is important.

Proliferation and differentiation of mouse embryonic stem cells lacking all lamins

Dear Editor, Lamins are the major components of the nuclear lamina (NL), which is located underneath the inner nuclear membrane. Diverse array of functions have been assigned to lamins, and alterations of lamins are associated with a number of human diseases. Of the three lamin genes in mammals, Lmna expresses all isoforms of Atype lamins, referred to as lamin-A/C, through alternative splicing, while Lmnb1 and Lmnb2 express B-type lamins. Despite subtype-specific sequence variations and different expression patterns, lamin proteins exhibit overall sequence similarity. Therefore, a potential functional redundancy among different lamin proteins has made it difficult to precisely address the role of lamins in mammals.
Metabolites from intestinal microbes shape Treg

Geochemical Characters of Water Coproduced with Coalbed Gas and Shallow Groundwater in Liulin Coalfield of China

To reveal the geochemical characters of water coproduced with coalbed gas and shallow groundwater, water samples were collected from 12 wells of coalbed methane and 7 wells of shallow groundwater. The pH, COD_(Mn), fCO_2, total dissolved solids (TDS), total hardness, and concentrations of metasilicic acid, sodium and kalium, calcium ion, magnesium ion, ammonium iron, bicarbonate ion, carbonate, chloride, sulfate ion, nitrate ion, fluoride, lithium, zinc, nickel, manganese, iron, boron, barium, etc. of the samples were measured. Research results showed the following: (1) Concentrations of TDS, chloride, fluoride, sodium and kalium, ammonium, iron, and barium in the water coproduced with coalbed gas exceeded the national standards of China; however, physical, chemical, and biological properties of shallow groundwater could meet the national standard. (2) The water produced from coalbed contained mainly Na–Cl?HCO_3, with average TDS of 4588.5 ppm, whereas shallow groundwater contained a mixture of chemicals including Na?Mg?Ca-HCO_3?SO_4 and Na?Mg-HCO_3?SO_4, with average TDS of 663.8 ppm. (3) In general, it was observed that bicarbonate and sodium accumulated in a reducing environment and deeper system, while depletion of hydrogen ions and dissolution of sulfate, calcium, and magnesium occurred in a redox environment and shallow system. (4) Sodium and kalium, ammonium, chloride, and bicarbonate ions were the main ions found in the study area.
Early Miocene Mosses from Weichang, North China, and their Environmental Significance

Twenty-seven moss specimens collected from the Guangfayong section (Early Miocene, 22.1 Ma) of the Weichang District, North China were investigated in the present study. Based on the morphological and anatomical features of gametophytes, all specimens were found to belong to three species: Leptodictyum riparium, Drepanocladus subtrichophyllus sp. nov., and Amblystegium varium, all of which belong to the family Amblystegiaceae. The microhabitats and living environments of fossil mosses were also investigated based on comparison with living mosses. The results suggest that these mosses grew primarily at the edges of rivers, streams, and lakes and favored being submerged in streams or lakes in the Weichang District in the Early Miocene.
