Earthworm fibrinolytic enzyme component A, a protein which functions both as a direct fibrinolytic enzyme and a plasminogen activator, was purified from the earthworm Eisenia fetida. Diffraction-quality single crystals of the protein were grown by the hanging-drop vapour-diffusion technique with ammonium sulfate as a precipitant. The crystals belong to the orthorhombic space group P2(1)2(1)2(1)...

The introduction of invasive earthworms initiates physical and chemical alterations in previously earthworm-free forest soils, which triggers an ecological cascade. most apparent step is the shift herbaceous plant community composition. However, some species, such as Arisaema triphyllum (jack-in-the-pulpit), persist where are present. It has been hypothesized that A. produces insoluble oxalate,...

Biological sensitivity to contaminant concentrations may vary substantially from species to species and the mode of toxic action may be highly selective and impair specific biological functions of the organisms. Physiological activities i.e. respiration, metabolism, feeding, breeding etc, of aquatic invertebrates are inhibited by the effects of pesticides [1]. Various workers have shown that ea...

We prove that the distance between two reflected Brownian motions outside a sphere in a 3-dimensional flat torus does not converge to 0, a.s., if the radius of the sphere is sufficiently small, relative to the size of the torus.

Negligible amounts of urea were excreted by fresh’ earthworms &urnbricus terrestris) ; however, on fasting, the quantity of urea in the excreta increased.notably (1). The oral administration of arginine was followed by an increased elimination of urea. The excretion of urea was also augmented, to a lesser extent, by the ingestion of citrulline with certain other amino acids. The data presented ...

Merchants of Houston contributed handsomely to make the prize list read like an invent...

In 1986, the Harvard Educational Review published Jim Cummins’s article “Empowering Minority Students: A Framework for Intervention,” which offered a theoretical framework for addressing the achievement gap of minority students. Despite considerable attention to this issue, educators have seen little encouraging progress. Even now, fifteen years after its original publication, Cummins’s article...
