This study examined the effects of long-term frozen storage (-20 °C for 5 months) of free amino acids (FAAs) and nucleotide-related compounds (NRCs) in muscle and hepatopancreas of the coconut crab Birgus latro. Although long-term frozen storage had little effect on FAA composition in muscle, the amounts of several FAAs increased in the hepatopancreas that may be the result of protein decom...

This study was undertaken to compare the efficiency of fresh and frozen-thawed buck semen on in vitro fertilization (IVF) of goat oocytes. Cumulus oocytes complexes (COCs) were collected by aspiration of 2-6 mm diameter follicles, which were obtained from slaughterhouse. Upon grading, only normal quality COCs were maturated in TCM-199 for 48 hours. The percentage of COCs reached to the M-II sta...

This is a retrospective quality assurance study of all frozen sections done at The Aga Khan University Hospital during a six year period (1986 to 1991). There were 1,031 frozen sections out of a cumulative total of 42,985 surgical specimens (2.39%). Nine hundred and severity-six (94.66%) were concordant. In 92 (8.9%) fresh specimens were brought from other hospitals of Karachi, in 37 cases (3.5...

background: the purpose of the study was to compare clinical pregnancy and delivery rates with fresh and frozen embryo transfer in patients admitted to shiraz- human assisted reproductive center with ovarian hyperstimulation syndrome (ohss). methods: ohss patients randomly divided in two groups, group a (n=50) with fresh embryo transfer and group b (n=50) with frozen embryo transfer. we used vi...

  The effect of gamma radiation (1, 3 and 5 kGy) on microbial quality of farmed rainbow trout (Oncorhynchus mykiss) fillets which were stored under frozen conditions (-20° C) was studied by measuring microbiological changes in 5 months. Gamma irradiation and increasing of frozen storage time had significant effects (P < /i>

Background: Several studies have recently investigated the role of leptin, the polypeptide hormone secreted primarily by white adipose tissue, in the reproduction of rodents, humans, and domestic animals. Materials and Methods: To investigate the in vitro effect of leptin on buffalo semen quality in equilibrated and frozen thawed semen, five healthy buffalo bulls (5 ejaculates from each bull) w...

Determining thawing times of frozen foods is a challenging problem as the thermophysical properties of the product change during thawing. A number of calculation models and solutions have been developed. The proposed solutions range from relatively simple analytical equations based on a number of assumptions to a group of empirical approaches that sometimes require complex calculations. In this...

the edible leafy vegetables contain nutritional ingredients that are necessary for human health and it is important that nutrients protection be monitored during processing and storage. the aim of this study was to study some organoleptic attributes of a very popular iranian meal named coco-sabzi, which was prepared with a mixture of edible grinded leafy vegetable pre-stored at different frozen...
