A small 2, 271-1 (600-gallon) prototype recirculating marine water system was designed and evaluated (26 months). The system employed a quaternary (mechanical, algal, bacterial and chemical) series of processing units with the aim of achieving long-t

The literature dealing with the use of ozone in wastewater treatment is extensive, but its reported applications to aquaculture are limited. The major limiting factors appear to be ozone toxicity and the cost of high-output ozone generators. Ozone to

The use of ozone as an oxidative supplement to biological filtration and to control epizootic microbial outbreaks coincident with maintaining a biological filter was investigated in a 2,271-1 (600 gallon) closed marine-water system. Under conditions

The acute in vitro actions of two potent melanocytolytic agents, hydroquinone (HQ) and β-mercaptoethanolamine (MEA), were determined in the B-16, Cloudman S-91 and Harding-Passey (HP) murine melanomas grown in vivo. Drug treated melanoma dice (5–4

Radioactive and nonradioactive methods used in the past for marking insects, and their applicability to orthopterous insects (sens. lat.), are evaluated on the basis of experimentation, prior field and laboratory experience, and critical analysis of

The acute in vitro action of adrenocorticotropin (ACTH) and corticosterone alone and in combination were determined in the Cloudman S-91 melanoma grown in vivo. Hormone-treated melanoma dice (5-240 min) were analyzed for tyrosinase activity (EC 1.14.

Serum tyrosinase activity in many persons with metastatic diseases was found to be significantly higher than activity in normal persons. The highest activity was observed in melanoma and breast carcinoma. The electrophoretic patterns of serum tyrosin

A number of biochemical aspects of melanogenesis were studied in 15 variously melanized human melanomas. The tryosinase activity was correlated with the degree of melanoma varied from 3,667 to 46,183 tryosinase units, in partially melanotic melanoma
