Objective: The purpose of the current study was to investigate the in vivo (analgesic, antidiarrheal, neurological, and cytotoxic) and in vitro (antioxidant, antimicrobial, thrombolytic and anthelmintic) activity of different fractions of methanolic extract of Momordica charantia. Materials and Methods: The antioxidant property ...
This study aimed to recycle sawdust and blood powder using Eisenia foetida earthworm and investigate some biochemical changes of these waste materials during vermicomposting. Blood powder was mixed with sawdust in proportions of 0, 5 and 10% and the mixture was allowed to pass through earthworm guts for four months. At intervals of 1, 2, 3, 4, 6, 8, 12 and 16 weeks, the biological activity (i.e...
Stock market liberalizations lead private investment booms. In a sample of 11 developing countries that liberalized, 9 experience growth rates of private investment above their non-liberalization median in the first year after liberalizing. In the second and third years after liberalization this number is 10 of 11 and 8 of 11 respectively. The mean growth rate of private investment in the three...
Urea is the most commonly used nitrogen fertilizer worldwide. The overused urea in agricultural fields may affect the soil organisms especially, the earthworms which are known well for their role in soil fertility. Earthworms are typically inferred as soil indicators without which soil fertility cannot be measured directly. An acute toxicity test of urea to earthworm (Eisenia fetida) was perfor...
By ingesting soil and organic matter in different horizons depositing casts on surface, anecic earthworms have large influence ecological processes. However, we still a limited understanding of the consequences earthworm casting activity nematode communities, role played by land use this relationship. Therefore, main objective study was to compare effect Amynthas adexilis (Thai, 1984) structure...
This study was conducted to evaluate the effect of different fresh feed supplemented to commercial diet on growth and survival of Oscar fish (Astronauts ocellatus) (initial weight: 1.58-1.70 g) during 60-day period. The husbandry environment consisted of glass aquariums appropriate to growth with a photoperiod cycle of 12 L: 12 D. The water temperature was kept at 28 ±1°C. 360 fries of Oscar (i...
Ecological niche theory asserts that invading species become established only if introduced propagules survive stochastic mortality and can exploit resources unconsumed by resident species. Because their transportation is not controlled by plant health or biosecurity regulations, soil macrofauna decomposers, including earthworms are probably introduced frequently into non-native soils. Yet even...
