The report elaborates experimental observations of magnetically induced convection in a nonconducting diamagnetic fluid. Suspension of Deionized (DI) water and Lycopodium pollen grains was used as the fluid in a test tube. Permanent magnets having field strength of 0.12T each were used to provide the static gradient magnetic field. The convections were visually observed and recorded using trave...

Huperzine A (HupA), a novel Lycopodium alkaloid isolated from Chinese folk medicine Huperzia serrata (Qian Ceng Ta), is a potent, selective and well-tolerated inhibitor of acetylcholinesterase (AChE). It has been proven to significantly improve the learning and memory impairment in Alzheimer's disease (AD) and vascular dementia (VaD) patients in China. Interestingly, our recent data indicate th...

Parasitological analysis of 5 sediment samples from latrine deposits spanning the time period from about 1880 to the 1930s are presented. Two sediment samples are from a latrine used by EuropeanAmericans. Three sediment samples are from latrines used by ChineseAmericans on the property of Wong Nim, an important member of the Chinese community. Two of the Chinese latrines were positive for human...

Investigation of the ignition behavior (minimum ignition temperature (MIT)) of hybrid mixtures of dusts and gases has been undertaken. This was achieved by performing series of test in the modified Godbert-Greenwald furnace. The materials used are, gases (methane, propane and hydrogen) and dust (starch, lycopodium, toner, wood and CN4 (mixture of bituminous and brown coal)). The test protocol f...

Endophytic fungi were used not only for their producing bioactive products but also for their ability to transform natural compounds. An endophytic fungus, isolated from medicinal plant Huperzia serrata, was identified as Umbelopsis isabellina based on the internal transcribed spacer of ribosomal DNA (rDNA-ITS) region. It was used to transform ursolic acid (1), a pentacyclic triterpene. Incubat...
