Topical becaplermin improves outcomes in work related fingertip injuries.

Background: Fingertip injuries are common and bear significant costs associated with treatment, lost work, and functional impairment. This study compared these factors in occupationally related fingertip injuries treated with becaplermin, a recombinant human platelet-derived growth factor, and those treated with surgical reconstruction.

Methods: This was a prospective controlled trial involving occupationally related fingertip injuries.

Trifolitoxin Production Increases Nodulation Competitiveness of Rhizobium etli CE3 under Agricultural Conditions.

A major barrier to the use of nitrogen-fixing inoculum strains for the enhancement of legume productivity is the inability of commercially available strains to compete with indigenous rhizobia for nodule formation. Despite extensive research on nodulation competitiveness, there are no examples of field efficacy studies of strains that have been genetically improved for nodulation competitiveness. We have shown previously that production of the peptide antibiotic trifolitoxin (TFX) by Rhizobium etli results in significantly increased nodule occupancy values in nonsterile soil in growth chamber experiments (E.

Population Dynamics of Phialophora gregata in Soybean Residue.

Brown stem rot frequently is more severe in no-till cropping systems. Population density of Phialophora gregata was monitored in soybean residue positioned below and on the soil surface. Current season residue was confined in nylon mesh bags that were placed in the field in the fall.

Impact of Planting 'Bell', a Soybean Cultivar Resistant to Heterodera glycines, in Wisconsin.

Although the soybean cyst nematode (SCN), Heterodera glycines, has been known to exist in Wisconsin for at least 14 years, relatively few growers sample for SCN or use host resistance as a means to manage this nematode. The benefit of planting the SCN-resistant cultivar Bell on a sandy soil in Wisconsin was evaluated in 1992 and 1993. A range of SCN population densities was achieved by planting 11 crops with varying degrees of susceptibility for 1 or 2 years before the evaluation.
