Serially diluted and agitated (SAD) drugs available commercially are in use with great faith because of the astonishing results they produce. The scientific viewpoint attached to the centuries-old therapy with SAD drugs, as in homeopathy, remained doubtful for want of appropriate research and insufficient evidence base. The conflicting points related to SAD drug mostly related to the level of c...

We analyze the patent filing strategies of foreign pharmaceutical companies in Chile distinguishing between "primary" (active ingredient) and "secondary" patents (patents on modified compounds, formulations, dosages, particular medical uses, etc.). There is prior evidence that secondary patents are used by pharmaceutical originator companies in the U.S. and Europe to extend patent protection on...

A gene has been introduced into soybeans to confer tolerance to glyphosate, the active ingredient in the herbicide, Roundup (Monsanto Co., St. Louis, Mo.) 1,2 Soybean varieties expressing this trait will enable farmers to use Roundup herbicide within the crop during the growing season. Previous studies have confirmed the safety of the introduced protein (5-enolpyruvylshikimate-3-phosphate synth...

This paper demonstrates the effectiveness of a new antimicrobial suture coating. An amphiphilic polymer, poly[(aminoethyl methacrylate)-co-(butyl methacrylate)] (PAMBM), inspired by antimicrobial peptides, was bactericidal against S. aureus in time-kill experiments. PAMBM was then evaluated in a variety of polymer blends using the Japanese Industrial Standard (JIS) method and showed excellent...

Ultrasonography allows the quantification of dermal density and echogenicity changes during the physiological senescence process. Some active ingredients are able to slow down the tissular degeneration and disorganization process. The purpose of this study was to assess the cutaneous changes induced by the topical use of products containing Viniferol(®) as active ingredient, using high-frequenc...

Blackbirds cause locally serious losses to rice. The Denver Wildlife Research Center, U. S. Fish and Wildlife Service, and the Rice Research Station, Louisiana State University Agricultural Center have been cooperating in tests to determine the efficacy of methiocarb seed treatments for protecting sprouting rice in Louisiana from blackbird damage. Results from four field tests (1980, 1982, 1983...

A new formulation of clomazone (the active ingredient in Command herbicide) was evaluated at four locations in 2010. The trade name of this product is Alert® and it was developed by Cheminova. The level of crop response and barnyardgrass control observed with Alert was similar to that of Command herbicide. Furthermore the rate structure and level of control observed by soil type appears to be t...

The decline in amphibians across the globe has sparked a search for the causes, and recent evidence suggests a connection with pesticides. However, for most pesticides, tests on amphibians are rare and conducted only for short durations (1 to 4 days) and without natural stressors. Recent studies have discovered that the stress of predator cues in the water can make insecticides much more lethal...

The insect growth regulator pyriproxyfen was evaluated as a surface treatment for control of three stored-product psocid pests Liposcelis bostrychophila Badonnel, Liposcelis decolor (Pearman), and Liposcelis paeta Pearman (Psocoptera: Liposcelididae). Nymphs were exposed for 35 d on a concrete surface treated with 2.3 mg of active ingredient/m2 pyriproxyfen. Exposure to pyriproxyfen significant...

Glyphosate, the active ingredient in the herbicide RoundUp, has increased dramatically in use over the past decade and constitutes a potent anthropogenic source of selection. In the southeastern United States, weedy morning glories have begun to develop tolerance to glyphosate, representing a unique opportunity to examine the evolutionary genetics of a novel trait. We found genetic variation fo...
