BACKGROUND Stored red cells undergo progressive structural and functional changes over time. We tested the hypothesis that serious complications and mortality after cardiac surgery are increased when transfused red cells are stored for more than 2 weeks. METHODS We examined data from patients given red-cell transfusions during coronary-artery bypass grafting, heart-valve surgery, or both betw...

The study was designed to investigate the effect of duration of frozen storage on the proximate profile of fishes lizadussmieri, sparidae, sciaenide and platycephalidae. The fishes were subjected to sixty days of frozen storage. Protein decreases with increasing duration of frozen storage; with the fresh samples (not frozen) having the highest protein content (13.02 ± 0.09%). while the least (1...

Changes in essential oils (EOs) content and composition of lemon verbena leave at different packaging methods (packaged with air, nitrogen, or under vacuum) and during storage period (0, 2, 4, 6 and 8 months) were determined. All the samples were hydrodistilled every 2 months during storage for EO content evaluation. EO composition was determined by gas chromatography and gas chromatography-mas...

This study was conducted to evaluate how acom size (small, medium and large) and acorn storage duration (0, 5 and 17 months) influenced Quercus petraea (Mattuschka) moisture content and germination. Acorn size and storage duration did not significantly affect acorn moisture content, but they significantly affected acorn germination performance. When averaged for three acorn sizes, loss of germi...
