Background and objectivesMyrica nagi Thunb., belonging to the family Myricaceae, is used in Indian traditional medicine treat diarrhea. This study aimed assess anti-diarrheal activity of aqueous extract stem bark Myrica (AEMN) using castor oil-induced diarrhea charcoal meal tests albino rats.

The rate of acetylene reduction was measured as a function of time after addition of 10% acetylene in Alnus, Casuarina, Ceanothus, Datisca, and Myrica. The maximum rate occurred after 45 to 60 seconds and was maintained for an additional 0.5 to 4 minutes before a decline in rate to 30 to 90% of the maximum. The rate then recovered to a value of 63 to 98% of the maximum. Removal of the shoot and...

Aqueous and ethanolic leaf extracts of Blighia sapida was assessed for some lipid profile parameters in normal albino rats. Daily administration of the extracts (50 and 100 mg/kg body weight) for 21days showed that the extract significantly (p<0.05) reduced the levels of total cholesterol, triglycerides and LDL-cholesterol in all the treated groups w hen compared with the control. While signifi...

Yeon-Koo Che and Ian Gale (1998) [CG, hereafter] studied the impact of imposing a cap on lobbying expenditures. They showed that a cap may lead to (1) greater expected aggregate expenditure and (2) a less efficient allocation of a political prize. In their comment, Todd Kaplan and David Wettstein (2005) [KW, hereafter] show that if the cap is not rigid (i.e., its effect on the cost of lobbying ...

The discovery of remarkably rounded pebbles by the rover Curiosity, within an exhumed alluvial fan complex in Gale Crater, presents some of the most compelling evidence yet for sustained fluvial activity on Mars. While rounding is known to result from abrasion by inter-particle collisions, geologic interpretations of sediment shape have been qualitative. Here we show how quantitative informatio...
