Taxus wallichiana, collected from the Himalayan region of Nepal, yielded, among others, three different endophytic fungi including Sporormia minima, Trichothecium sp., and an unidentified dimorphic fungus. Each was shown to produce paclitaxel in a culture medium. Each of these fungi represents a new report as a paclitaxel producer. The production of(More)
Some empirical evidence suggests that the expected real interest and expected inflation rates are negatively correlated. This hypothesis of negative correlation is sometimes known as the Mundell-Tobin hypothesis. In this article we reinvestigate this negative relation from a long-term point of view using cointegration analysis. The data on the historical(More)
In this article, monthly data on 30-year fixed-rate conventional mortgage rate and 10-year constant maturity Treasury yield for the period from April, 1971 to December, 2003 is used to test for the integration of the mortgage market with the broader capital markets.

Using the model that follows the dynamic simultaneous equation models of Pesaran (1997) and Hsiao (1997), we find evidences of long-run relationships between the US real interest rate and the other six G-7 countries. However, the estimated(More)
An ethanolic extract of Podocarpus neriifolius D. Don (Podocarpaceae) showed antiproliferative activity against two major tumor cell lines, viz. human HT-1080 fibrosarcoma and murine color 26-L5 carcinoma. Bioassay guided fractionation showed the highest antiproliferative activity in chloroform-soluble fraction. Nagilactone C, the major constituent of this(More)
