Livers cold preserved during variable periods of ischemia suffer functional, morphological and hemodynamic alteration, which are exacerbated when they are reperfused. One important injury is glycogen depletion during cold ischemia/ reperfusion. How liver can restore their energy during reperfusion is related with the preservation time, nutritional status of the donor, and the preservation solut...

It has been documented that the serum complement activities measured by hemolytic assay (CH50) are decreased after storage of sera at a low temperature in some patients with chronic hepatitis C. However, the mechanism of this phenomenon has not been identified yet. Here, we tried to elucidate factors involved in the cold activation of complement (CAC). To clarify what pathway is activated in CA...
BACKGROUND Preservative effect of melanin-free extract of Sepia esculenta ink (MFESI) on Sparus latus fillet has been verified in our previous work. This study aims to further approach the mechanism of MFESI for extending the shelf-life of fish fillet during cold storage. Tilapia fillets were treated with different dosage of MFESI (0, 15, 25 and 35 mg/ml) and packed with preservative film for s...
The distribution channel of meat by-products from the pig farm to the final consumer can include a meat processor, wholesale market, wholesaler, retailer, and butcher shop. Bacterial contamination at any of these steps remains to be a serious public health concern. The aim of this study was to evaluate the distribution channel and microbial characteristics of pig by-products in Korea. Upon eval...
In this research, the survival of probiotic microorganisms in yogurts stored at room temperature (cold chain interruption conditions) was studied. Milk inoculated with yogurt bacteria (mixed culture of Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus) and a single probiotic culture (L. acidophilus LA-5 or Bifidobacterium lactis Bb- 12 or L. rhamnosus HN001 or L. paracase...
Litchi is a non-climacteric subtropical fruit of high commercial value. The shelf life of litchi fruit under ambient conditions (AC) is approximately 4-6 days. Post-harvest cold storage prolongs the life of litchi fruit for up to 30 days with few changes in pericarp browning and total soluble solids. However, the shelf life of litchi fruits at ambient temperatures after pre-cold storage (PCS) i...
The effect of cold storage (5 C, 24 h) and heat treatment (60 C, 5 min) of milk on activities of free and membrane-bound xanthine oxidase has been studied. Both treatments enhanced total xanthine oxidase activity in milk. Activity of membrane-bound xanthine oxidase increased and free xanthine oxidase decreased in buttermilk while it increased in skim milk on cold storage. Heat of milk increased...
BACKGROUND This study compared the use of static cold storage versus continuous hypothermic machine perfusion in a cohort of kidney transplant recipients at high risk for delayed graft function (DGF). METHODS In this national, multicenter, and controlled trial, 80 pairs of kidneys recovered from brain-dead deceased donors were randomized to cold storage or machine perfusion, transplanted, and...
paste of big head carp fish was prepared based on three formulas and was selected base on organoleptic properties test results. the product was then divided into three portions of: sample 1 (control), sample 2 (containing 0.01% butylated hydroxy anisole bha antioxidant) and sample 3 (containing 0.02% antioxidant bha). to determine the shelf life, the samples were frozen and kept in cold storage...
