Effects of Ginseng Protein on Gut Microbiota and BDNF/TrkB Signaling Pathway in Alzheimer s Disease Mice

[Objectives] To investigate the effects of ginseng protein on gut microbiota and BDNF/TrkB signaling pathway in Alzheimer s disease (AD) mice. [Methods] D-galactose/AlCl 3 co-induction was used to establish AD model, and mice were randomly divided into normal group 1, normal group 2, model group 1, model group 2, ginseng protein group, and microbiota transplantation group. Morris water maze experiment was used to evaluate learning and memory ability, and Western blot method was used to detect the expression of APP, p-Tau, BDNF, TrkB, p-TrkB proteins in brain tissue, and 16S rDNA was used to detect diversity of fecal microbiota. [Results] Ginseng protein and microbiota transplantation can shorten the escape latency of mice ( P <0.05), increase the number of crossing platforms ( P <0.05), reduce the expression of APP and p-Tau proteins in brain tissue ( P <0.05, P <0.01), increase the expression of BDNF, p-TrkB, p-TrkB/TrkB proteins ( P <0.05, P <0.01), and reduce the abundance of Alloprevotella, Ruminococcaceae _UCG-014, Prevotellaceae _UCG-001, and Ruminococcus _1 ( P <0.05, P <0.01). [Conclusions] The action mechanism of ginseng protein anti AD may be through regulating gut microbiota diversity and activating the BDNF/TrkB signaling pathway.

The Dos and Don’ts of the African Continental Free Trade Agreement Pose the Ghana’s Maritime Industry Vis-A-Vis Its National Industrialization Drive

The direct and indirect immensely contributions of free trade blocs/single market integration to the steadilygrowth of developed emergence and least developed economies are unmeasurable. The increasing insatiable demand and approval of the free trade model by almost all of the six continents to enhance their economic development has proved that its benefits have indeed outweighed the challenges. Therefore, this research just like the other internationally recognised literatures on this market system, intends to analysis the impacts of the important/dos, don’ts, opportunities, prospects and other important factors of the recent AU member States unanimously endorsement of AfFCTA’s implementation, will have on Ghana’s maritime industry. The possible quantitative findings in this study do uphold its immensely potential benefits impact on the African and Ghana’s maritime industry development and at the same time, indicate an irresistible gap pertaining to the downward progress of its implementation within the sector. These findings have apparently revealed that loss of revenue from scrapping off customs tariffs carries the highest percentage of all the challenges facing AfCFTA’s implementation and recommend that there must be an effective investment-oriented measures-FDI in harnessing the opportunities and prospects embedded in AfCFTA so as to accelerate Ghana’s maritime industry development in its implementation process.

Total saponins of Panax ginseng effects on proliferation and differentiation of human embryonic neural stem cells and in a Parkinson's disease mouse model

BACKGROUND： Total saponins of Panax ginseng （TSPG） exhibits neuroprotection against Parkinson＇s disease in the substantia nigra. OBJECTIVE： To investigate the effects of TSPG on human embryonic neural stem cells （NSCs） proliferation and differentiation into dopaminergic neurons using in vitro studies, and to observe NSC differentiation in a mouse model of Parkinson＇s disease, as well as behavioral changes before and after transplantation. DESIGN, TIME AND SETTING： In vitro neural cell biology trial and in vivo randomized, controlled animal trial were performed at the Institute of Basic Medical Sciences, Chongqing Medical University between September 2004 and December 2007. MATERIALS： TSPG （purity 〉 95%） was isolated, extracted, and identified by Chongqing Academy of Chinese Materia Medica. Recombinant human basic fibroblast growth factor （bFGF） and recombinant human epidermal growth factor （EGF） were purchased from PeproTech, USA. A total of 25 C57/BL6J mice, aged 18-20 weeks were included. Twenty were used to establish a Parkinson＇s disease model with i.p. injection of MPTP （1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine） and TSPG alone or combined with interleukin-1 （IL-1）-treated NSCs prior to transplantation into the corpus striatum. The remaining five mice were pretreated for 3 days with TSPG prior to MPTP injection, serving as the TSPG prevention group. METHODS： Primary NSCs were isolated, cultured and purified from embryonic cerebral cortex. Immunocytochemistry was employed to detect specific antigen expression in the NSCs. In vitro experiment： （1） to induce proliferation, NSCs were treated with TSPG, EGF＋bFGF, or TSPG＋EGF＋bFGF, respectively; （2） to induce dopaminergic neuronal differentiation, NSCs were treated with TSPG, IL-1, or TSPG＋IL-1, respectively. MAIN OUTCOME MEASURES： In vitro experiment： the effects of TSPG on NSCs proliferation were evaluated with flow cytometry and MTT assay. Tyrosine hydroxylase expression was determined by immunocytochemistry assay to observe effects of TSPG on dopaminergic neuronal differentiation. In vivo experiment： differentiation of grafted NSCs in the mouse brain was determined by immunohistochemical staining. Behavioral changes were evaluated by spontaneous activity frequency, memory function, and score of paralysis agitans. RESULTS： （1） NSCs were cultured and passaged for more than three passages. Immunocytochemistry revealed positive nestin staining, as well as neurofilament protein and glial fibrillary acidic protein. （2） TSPG significantly increased NSC proliferation, in particular when combined with EGF and bFGF, which was twice as effective as FGF or bFGF alone. TSPG also induced dopaminergic differentiation in NSCs, in particular when TSPG was added together with IL-1, resulting in an effect five times greater than that of IL-1 alone. （3） At day 30 following transplantation, most NSCs in the TSPG prevention group differentiated into dopaminergic neurons, and the scores of paralysis agitans, spontaneous activity, and memory function were significantly increased compared with TSPG alone or TSPG＋IL-1 groups （P 〈 0.05）. CONCLUSION： TSPG stimulated NSC proliferation, in particular when combined with FGF and bFGF. TSPG significantly induced dopaminergic neuronal differentiation of NSCs, and the effect was greater when combined with IL-1. In addition, TSPG greatly improved behavior in the Parkinson＇s disease mouse model following NSC transplantation. Following NSC transplantation, TSPG pretreatment exhibited superior efficacy over either TSPG alone or TSPG in combination with IL-1, in terms of behavioral improvements in the Parkinson＇s disease mouse model.

Leak Detection and Repair (LDAR) Standard Review for Self-Inspection and Management for VOC Emission in China’s Traditional Energy Chemical Industry

The emission of the traditional energy chemical industry accounts for 20% of the total manmade VOC emission in China, of which coal chemical and petrochemical plants are one of the most important VOC emission sources. VOC emission sources mainly include the leakage of oil refinery units and equipment, pipes and valves, respiration and leakage of various types of storage tanks, effusion of oils during loading and unloading, effusion of sewage treatment systems, all kinds of process tail gas, etc. In this paper, the current management status of VOC emission in China’s coal chemical industry and petrochemical industry are analyzed, which divides VOC management into intentional and fugitive emission. The Leak Detection and Repair (LDAR) management method and technology for equipment, pipes and valves implemented in the United States are studied to propose self-inspection management methods and measures for VOC emissions in the energy chemical industry, providing strategies and recommendations for energy conservation, emission reduction and cleaner production in the traditional energy chemical industry.

Strategies for Prioritizing Ecological Construction with Consideration of Agricultural Industry Development in Northern China’s Agro- pastoral Ecotone : A Perspective of Opportunity Cost

In northern China’s agro-pastoral ecotone,there are conflicts between agricultural industry and ecological construction resource competition,and also problems urgently to be solved for economic growth and sustainable ecological improvement.Taking the development concept of"lucid waters and lush mountains being mountains of gold and silver"as the guiding principle of prioritizing ecological and green development,this paper studied the strategies for prioritizing ecological construction with consideration of economic development of agricultural industry from the perspective of opportunity cost.Through the analysis of opportunity cost,externality,and Pareto optimal theory,and using the calculation method of the unit equivalent factor value of terrestrial ecological service function,this paper calculated the ecological service value of forest,grassland,and farmland.It found that the ecological value of forest and grassland per unit area was greater than the ecological value of agricultural industry.This indicates that the opportunity cost of farmland for ecological construction was less than that of agricultural industry.Based on the theoretical and quantitative analysis,it came up with recommendations for establishing a comprehensive system for prioritizing ecological construction with consideration of agricultural industry development and establishing and improving the incentive mechanism of ecological construction.
