The degradation of two oxime carbamate pesticides, oxamyl and methomyl, was investigated in anoxic solutions containing various metal ions and reducing agents. In reagent-free solutions, these carbamates degrade slowly via base-catalyzed elimination. Rates of carbamate degradation are accelerated by Fe(II)

This is a case report and literature review of a 30.8 pound cystosarcoma phyllodes tumor resected in a 54-year-old female. Starting at age 19, the patient had noted a small breast tumor that continued to grow over the years. Pathology
Structural modifications were made to a previously described acyl dipeptide caspase inhibitor, leading to the oxamyl dipeptide series. Subsequent SAR studies directed toward the warhead, P2, and P4 regions of this novel peptidomimetic are described herein.

The concept of B-esterase buffering against anti-cholinesterase (ChE) insecticide toxicity has been extensively researched in mammalian species. Presumably due to relatively low levels of anti-ChE detoxifying enzyme activity in birds, however, avian species are often more susceptible to the toxic
Acetylcholinesterase (AChE) activity has been used to test the exposure of mollusk bivalves to pesticides and other pollutants. The Pacific oyster Crassostrea gigas is a species with a worldwide distribution, and it has a high commercial value. The use of
