The demand for uniformly sized and shaped produce that are aesthetically pleasing results in significant food waste throughout the world. Cucumber waste is a major agricultural waste product in a number of countries, especially areas with high pickle production. Opportunity exists for wastewater treatment plants containing anaerobic digesters to utilize cucumber agricultural and industrial waste for biogas production.

Glycerol was systematically added to the primary digester from 0% to 60% of the organic loading rate (OLR). The optimum glycerol loading range was from 25% to 60% OLR.

The endogenous expression of these growth factors in response to brain injury is not well understood. We have utilized the Swiss-Webster mouse, treated with the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), and a quantitative polymerase chain reaction assay to examine changes in endogenous synthesis of mRNA for both aFGF and bFGF in the striatum and substantia nigra.

Hershey Medical Center, 48 patients; Southeastern Cancer Study Group [SECSG], 162 patients). As the criteria for patient selection and drugs used were similar, we have pooled the data to analyze the effects of these two treatments.

Forty-one patients (27 females and 14 males) with biopsy-proven granulomatous inflammation were seen at an orbital clinic between 1978 and 1989. The mean age at presentation was 40.
