Crude glycerol impurities improve lipase production by .

Crude glycerol, a by-product of biodiesel production, was employed as the carbon source to produce lipase using . Under identical fermentation conditions, cell growth and lipase activity were improved using crude glycerol instead of pure glycerol. The impacts of crude glycerol impurities (methyl ester, grease, glycerol, methanol, and metal ions Na, Ca, and Fe) on lipase production were investigated.

Synthesis of a novel nano-rod-shaped hierarchical silicoaluminophosphate SAPO-11 molecular sieve with enhanced hydroisomerization of oleic acid to iso-alkanes.

In this article, a novel nano-rod-shaped SAPO-11 molecular sieve (SAPO-11-A-F) with a thickness of 100 nm was successfully fabricated by the seed-induced steam-assisted method using the cationic surfactant cetyltrimethylammonium bromide (CTAB) as a mesoporous template and a nonionic copolymer poly(ethylene oxide)--poly(propylene oxide)--poly(ethylene oxide), F, as the crystal growth inhibitor. The fabricated nano-rod-shaped SAPO-11-A-F possessed nanocrystalline size, a hierarchical porous structure, and enhanced acidic sites. The added CTAB was mainly used to enhance the mesoporous structure and acid, and F acted as a grain growth inhibitor.

BIBLIOMETRIC ANALYSIS OF ACUPUNCTURE RESEARCH FRONTS AND THEIR WORLDWIDE DISTRIBUTION OVER THREE DECADES.

Background: Considerable research has been conducted on acupuncture worldwide. This study chronologically examined the changing features and research fronts of acupuncture and elucidated the differences among the six most productive countries.

Methods: Bibliographic coupling is a powerful tool for identifying the research fronts of a field.

[A bibliometric overview of traditional Chinese medicine research in Medline].

Objective: To analyze the publication activity in traditional Chinese medicine (TCM) and learn more about the development and perspective of TCM as well as its subfields.

Methods: TCM-related publications (from 1964 to 2008) indexed in Medline were analyzed, including publication number and proportion of TCM papers, TCM clinical research papers, papers in TCM subfields such as Chinese medicine, Chinese herbs and acupuncture. We also analyzed the journals in which they got published.

[Current status of research on complementary and alternative medicine in the United States: in comparison with that on traditional Chinese medicine in China].

Researches on complementary and alternative medicine (CAM), including traditional Chinese medicine (TCM), are attracting more and more attention in the United States, and their scale and investment are progressively increasing. The differences between China and the United States in application of TCM therapies, background of Eastern and Western knowledge, thinking model, as well as the recognition of TCM theories lead to the differences in content and design of TCM researches.

[Analysis of international application of complementary and alternative medicine].

Traditional Chinese medicine (TCM) is an important part of complementary and alternative medicine (CAM) in the world medical market. The basis of globalization of TCM was to make sure the current situation of CAM and the role that TCM plays. It will improve the application and reputation of TCM by analyzing the global usage rate, sort of diseases, social-demographic characteristics of users and medical economics of CAM.
