Squid Todarodes pacificus
suwari gels, set at various temperatures and times, and acid-induced kamaboko gel, which was prepared by soaking suwari gel in 5% acetic acid for 20 h, were studied to evaluate the mechanical properties that are affected by setting conditions.
Unset squid meat paste did not form a gel when soaked in acetic acid. The breaking strength of both suwari gel and acid-induced kamaboko gel showed a tendency to increase with setting temperature and time. SDS-PAGE analysis of suwari gel and acid-induced kamaboko gel, which were set at various temperatures and times, showed that myosin heavy chain (MHC)
was observed at 30°C only for the first hour. The intensity of the MHC band at 30°C gradually decreased with setting time,
while the intensity of the polymer band gradually increased with setting time. These results suggest that the protein-protein
bonds in suwari gel affect the final texture of acid-induced kamaboko gel. Based on the analysis of the mechanical properties, and in consideration
of the fact that the purpose of this experiment was to reduce energy usage, the best setting condition was determined to be
40°C for 3 h. 相似文献

A 32-year-old woman attempted suicide by ingesting Gloriosa bulbs and died approximately 2 days later. Toxicological examination revealed a potentially fatal blood concentration of colchicine (0.096 mg/L). In addition to the increased mitotic figures in the gastrointestinal mucosa, a unique finding for acute colchicine intoxication, pathological examination showed microvesicular lipid droplets in the liver, kidney, heart, and conduction system. Furthermore, central chromatolysis of neurons was observed in the pontine nucleus, medial accessory olivary nucleus, nucleus of the solitary tract, and nucleus ambiguus. Grumose degeneration of the cerebellar dentate nucleus was also evident. These pathological findings may help identify colchicine intoxication, even in the absence of evidence suggesting ingestion during autopsy. Moreover, pathological changes in the heart and central nervous system may be associated with the development of serious complications of acute colchicine intoxication. 相似文献

We tested whether the predation dynamics of chub mackerel Scomber japonicus and spotted mackerel S. australasicus on young anchovy Engraulis japonicus relates to individual growth characteristics of the prey and could account for the growth-selective survival predicted by
recruitment hypotheses. Juvenile and adult mackerel were sampled along with their young anchovy prey field in 2004 (juvenile
mackerel and larval anchovy) and 2005 (adult mackerel and juvenile anchovy) off the Pacific coast of Honshu, Japan. The recent
5-day mean growth rate of larval and juvenile survivors and prey found in the stomach of mackerel was estimated from the otolith
microstructure. No significant difference was found between the recent growth of larval or juvenile survivors and that of
preyed individuals. We conclude that despite a relatively small body size, the high activity level and predation skills displayed
by mackerel prevent fast-growing larvae and early juveniles from benefitting in terms of the expected survival advantage over
slow-growers. Hence, growth-selective predation mortality of larval fish would depend on the feeding ecology of the predator
rather than predator size. Selection for fast growth is more likely to occur under predation pressure from invertebrate organisms
and small pelagic fish specialized on zooplankton, such as herring and anchovy. 相似文献

The nasal conchae of the pika and volcano rabbit were studied by gross examination and by serial histological sections stained with hematoxylin. The organization of the nasal conchae were compared with those of the domestic rabbit, with the goal of providing data for the determination of taxonomic relationship of the pika and the volcano rabbit to the domestic rabbit. This relationship is of interest because of a recent classification of these animals as Lagomorphs. 相似文献

The concentration of parvalbumin was determined in various types of chicken muscle by immunological analysis and was compared with that of myoglobin. Parvalbumin was present specifically in skeletal muscle and absent in cardiac and gizzard muscle; exceptionally, neither parvalbumin nor myoglobin was detected in white breast muscle. The wing and leg red muscles, which had larger amounts of myoglobin, contained smaller quantities of parvalbumin. In these muscles, the concentration of parvalbumin was inversely related to that of myoglobin (correlation coefficient = -0.69). Both myoglobin and parvalbumin were observed in the legs of 18-d-old embryos; the parvalbumin content exceeded that of myoglobin until the birds were 4 to 6 weeks old, but the relationship was reversed thereafter. Myoglobin in gizzard muscle was present in 18-d-old embryos and increased markedly at hatching; it was already present in cardiac muscle at an early embryonic stage, increasing gradually until 14 weeks after hatching. 相似文献
