A comparative study on the composition, biodiesel production and fuel properties of non-edible oils from Euphorbia lathyris L. (EL), Sapium sebiferum L. (SS), and Jatropha curcas L. (JC) was conducted. Under optimal conditions, the FAME content and yield of the three oils were greater than 97.5. wt.% and 84.0%, respectively. The best biodiesel was produced from EL due to its high monounsaturation (82.66. wt.%, Cn: 1), low polyunsaturation (6.49. wt.%, Cn: 2, 3) and appropriate proportion of saturated components (8.78. wt.%, Cn: 0). Namely, EL biodiesel possessed a cetane number of 59.6, an oxidation stability of 10.4. h and a cold filter plug point of -11 °C. However, the cetane number (40.2) and oxidative stability (0.8. h) of dewaxed SS kernel oil (DSSK) biodiesel were low due to the high polyunsaturation (72.79. wt.%). In general, the results suggest that E. lathyris L. is a promising species for biodiesel feedstock. © 2010 Elsevier Ltd.

Enterobacterial repetitive intergenic consensus (ERIC)-PCR was applied to analyze the difference of intestinal microbial community diversity between healthy and orally infected rabbits with Entamoeba histolytica. The dynamic changes in different parts of digestive system including the duodenum, jejunum, ileum, caecum, and rectum in healthy and infected rabbits at different time points were also tested. The intestinal microbial community of the control healthy rabbits was steady, and the total number of ERIC-PCR bands in the control healthy rabbit was the least in the rectum and the most in the caecum. ERIC-PCR bands of orally inoculated rabbits did not obviously change until 24 h after postinoculation (p.i.). The numbers of the ERICPCR bands gradually decreased from 24 to 72 h p.i., and then, with the development of disease, the band numbers gradually increased until 6 days p.i. Sequence analysis showed that the nucleotide sequence homologies of the fragment about 1,200 bp of infected ileum sampled at 32 h p.i. were above 95 % with Sinorhizobium meliloti enterobacterial, Erwinia amylovora and Salmonella typhimurium, and the nucleotide sequence homologies of the fragment about 300 bp of infected ileum sampled at 48 h p.i. were more than 90%with Xanthomonas campestris enterobacterial, Yersinia enterocolitica subsp., Shigella flexneri, S. meliloti enterobacterial, Yersinia pestis, Klebsiella pneumoniae subsp., and Escherichia coli. The prominent bacteria had changed after E. histolytica infection. The DNAstar of staple of ERICPCR showed that aerobe and facultative aerobe (E. coli, Shigella, and Salmonella) became preponderant bacilli in the intestine of orally infected rabbits with E. histolytica. ©Springer-Verlag 2012.

Mycorrhiza | Year: 2014
Both arbuscular mycorrhizal (AM) fungi and root hairs play important roles in plant uptake of water and mineral nutrients. To reveal the relative importance of mycorrhiza and root hairs in plant water relations, a bald root barley (brb) mutant and its wild type (wt) were grown with or without inoculation of the AM fungus Rhizophagus intraradices under well-watered or drought conditions, and plant physiological traits relevant to drought stress resistance were recorded. The experimental results indicated that the AM fungus could almost compensate for the absence of root hairs under drought-stressed conditions. Moreover, phosphorus (P) concentration, leaf water potential, photosynthetic rate, transpiration rate, stomatal conductance, and water use efficiency were significantly increased by R. intraradices but not by root hairs, except for shoot P concentration and photosynthetic rate under the drought condition. Root hairs even significantly decreased root P concentration under drought stresses. These results confirm that AM fungi can enhance plant drought tolerance by improvement of P uptake and plant water relations, which subsequently promote plant photosynthetic performance and growth, while root hairs presumably contribute to the improvement of plant growth and photosynthetic capacity through an increase in shoot P concentration. © 2014, Springer-Verlag Berlin Heidelberg.

Cupping therapy of Chinese medicine is able to relieve a variety of diseases or clinical conditions, which results from the comprehensive effects of multiple types of stimulation exerted onto the regional acupoint areas. Among the stimuli, the negative pressure from cupping is one of the main factors inducing therapeutic effects. In the present paper, the authors review development of researches on the underlying mechanism of therapeutic effects of cupping-negative pressure from 1) the factor of intra-cup negative pressure; 2) influence of intra-cup negative pressure on cup-blackspot formation; 3) influence of cupping on regional blood vessels and blood flow; 4) effect of cupping on regional ultrastructure of the capillary in the raw-surface tissue; 5) effect of cupping-negative pressure on regional endothelial cells; and 6) biological effects of negative pressure drainage. Generally, cupping induced negative pressure can dilate local blood vessels to improve microcirculation, promote capillary endothelial cells repair, accelerate granulation and angiogenesis, etc., in the regional tissues, normalizing the patients' functional state at last.

Astilbin in 28 Smilax glabra (red and white cross-section) from different sources was determined by HPLC. Pharmacodynamics and component of S. glabra was investigated through inflammation experiment (penetration type). The analysis was performed on a Hypersil ODS2 column (4.6 mm x 250 mm, 5 microm) with the mobile phase of acetonitrile and 0. 1% acetic acid aqueous (21: 79) at a flow rate of 1.0 mL x min(-1). The detection wavelength was 291 nm, and the column temperature was 25 degrees C. Anti-inflammatory effect was compared from two type cross-section of Smilax glabra in capillary permeability experiment. Linear correlation was good in the range of 0.003 379-4.004 microg, and the average recoveries were 100.1%, 101.9%, 99.3%, respectively. The content of astilbin in white and red transverse section were 0.19%-2.46% and 2.10%-5.92%, respectively. Anti-inflammatory efficiency of sectioned red and white were were 21% and 32%, respectively. Astilbin content and anti-inflammatory effect is significantly different between red and white transverse section of S. glabra, the content of astilbin is not positively related with anti-inflammatory effect.

In classical virus spread model, the virus spreading process is described by infected probability, this process ignored some spreading details and the duration of contact. For this reason, we proposed a delay included dynamic virus spreading model and simulated the viruses' spreading process by cellular automata method. The unexpected result shows that the individual's moving behavior can hinder the viruses' spreading process as delay is existed. This conclusion broke with the idea that individuals' moving behavior improves viruses' spreading process, which is helpful for people to understand viruses' spreading phenomenon. © 2013 IEEE.

To study the feasibility of repairing bone defect by combined autologous bone marrow transplantation, cuttebone, and sodium hyaluronate. Forty-eight New Zealand rabbits were randomly divided into four groups. The 10-mm bone defect of the radial shaft animal model was established, with the periosteum remained. Rabbits of Group A were treated by autologous bone marrow transplantation, cuttlebone, and sodium hyaluronate. Those of Group B were treated by autologous bone marrow transplantation and cuttlebone. Rabbits of Group C were implanted with cuttlebone and sodium hyaluronate. And rabbits of Group D were taken as the blank control. There were twelve rabbits in each group. All rabbits were sacrificed, and the general histological examination, X-ray test, the pathohistological observation and scoring, the new born formation area measurement were performed at 2-week, 4-week, 8-week, and 12-week after transplantation respectively. The capacities for bone transplantation and defect repairing were compared and analyzed as well. The bone defect of Group A was completely repaired at week 12. The comprehensive indices at each time point were superior to those of the rest groups, showing statistical significance (P<0.05). The bone repair in Group B and Group C were somewhat poor, with the repairing effect inferior to that of Group A. The bone repairing was better in Group B than in Group C. Most portion of the bone defect in Group D was filled with fibrous tissue and muscular tissue, with little bone repairing. The combined autologous bone marrow transplantation, cuttlebone, and sodium hyaluronate showed obviously synergistically bone forming capacities. It could be taken as a substitute material for transplantation.

To observe the effect of needle-implantation (NI) at "Neiguan" (PC 6) on the expression of myocardial transforming growth factor-beta 3 Protein(TGF-beta 3) and mRNA in Chinese miniswine with myocardial ischemia (MI) injury. A total of 32 Chinese Guizhou miniswine were randomly and equally divided into Sham-operation group, model group, NI-PC 6 group and NI-Geshu (BL17, NI-BL17) group. MI injury model was established by occlusion of the descending anterior branch of the left coronary artery. Two acupuncture needles (veterinary use) were separately and subcutaneously implanted into "Neiguan" (PC 6) and "Geshu" (BL17) areas for 7 days. TGF-beta 3 protein and mRNA expressions were determined by Western blot and real-time PCR techniques, separately. In comparison with the sham-operation (sham) group, TGF-beta 3 protein and mRNA expressions in model group were upregulated significantly (P < 0.05). While compared with the model group, myocardial TGF-beta3 mRNA expression was upregulated considerably in NI-PC 6 group (P < 0.01), rather than in NI-BL17 group (P > 0.05), and myocardial TGF-beta 3 expression in both NI-PC 6 and NI-BL17 groups was upregulated obviously (P < 0.01). Comparison between NI-PC 6 and NI-BL17 groups showed that the expression levels of myocardial TGF-beta 3 protein and mRNA were significantly higher in NI-PC 6 group than in NI-BL17 group (P < 0.05). Needle-implantation of "Neiguan" (PC 6) can upregulate myocardial TGF-beta 3 protein and mRNA expression in MI Chinese miniswine, which may contribute to its effect in improving the ischemic myocardial injury by way of enhancing the angiopoiesis.
