Accurate interpretation and correlation of tissue spectroscopy with pathological conditions requires disease-specific tissue metabolite databases; however, specimens for research are often kept in frozen storage for various lengths of time. Whether such frozen storage results in alterations to the measured metabolites is a critical but largely unknown issue. In this study, human prostate tissue...

A variety of transplantable mouse, rat, hamster, and ehieken tumors have been suecessfully stored at 7 6 ~ C. (dry-ice chest) for a period of 1 year. These tumors are seven sarcomas, a mammary carcinoma, a skin carcinoma, a bladder carcinoma, a lung carcinoma, two lymphosarcomas, a glioma, a leukemia, a virus leukemia, a pancreatic tumor, and a small intestine tumor. Transplantability of a majo...

The effect of irradiation on color, lipid oxidation, and volatile production of precooked, irradiated turkey breast during frozen storage was studied. Turkey breast muscles were precooked, aerobically or vacuum-packaged, irradiated at 0, 2.5, or 5.0 kGy using a linear accelerator (electron beam), and then frozen-stored at -40 C. Lipid oxidation, volatiles, color values, gas production, and oxid...

This work deals with changes in functional and sensory properties during freezing and frozen storage of Atlantic mackerel pre-treated by high hydrostatic pressure processing (HPP)....

The effect of aqueous solution of citric acid (CA) on the lipid stability of the European catfish (Silurus glanis) fillets during frozen storage (up to 6 months) was investigated. Rancidity development was measured by several biochemical indices (free fatty acids, peroxides and TBA) and complemented by the measurement of expressible moisture and sensory evaluation (flesh odor, consistency and f...

The U.S. Department of Agriculture's tertiary Pathogen Modeling Program (PMP) model for survival and growth of Salmonella enterica ser. Typhimurium definitive type 104 (DT104) on chicken skin stored for 0 to 8 h at 5 to 50°C was evaluated for its ability to predict survival and growth of the same organism on chicken skin after frozen storage for 6 days at -20°C. Experimental design and methods ...

AIMS To determine the suitability of primary gel separation tubes for the storage of frozen sera intended for serological testing. METHODS Blood samples from 102 patients were collected into gel separation tubes. The sera from these samples were split between the primary gel separation tubes and conventional plastic storage tubes and frozen. A year later, the tubes were thawed and anti-rubell...
