    Notes: To most effectively utilize the valuable functional properties of soy protein isolates (SPI), it is necessary to study their functional behavior in complex systems where interaction with other components (e.g., proteins, fats, carbohydrates, etc.) is expected to occur. The effect of mixing SPI and sodium caseinates (SC) on SPI emulsion stabilizing properties (ESP) was evaluated by determining emulsion stability, % adsorption of proteins onto the oil globule surface and SDS-polyacrylamide gel electrophoretic analysis. In emulsions prepared using the shearing force method, the high ESP (77%) of SPI was decreased to a low level (15%)–the same as that for SC–by mixing SC with the SPI. The main reason for this phenomenon is the initial coating of the oil globules with a thin layer of SC which prevents adsorption of SPI.

    Notes: A highly significant association of an amino acid sequence, ‘70Q71R72R73A74A’ located on the DRβ-1 chain, with rheumatoid arthritis (RA) was confirmed in Japanese patients using polymerase chain reaction. The ‘70QRRA74A’ is the most plausible candidate of susceptibility epitope in Japanese RA patients. The patients carrying the sequence showed slightly higher but not significant familial incidence. The positivity of the ‘QRRAA’ showed no effect on the positivity of the rheumatoid factor, rheumatoid nodules, and extra-articular signs. Also no significant differences in other clinical parameters (ESR, CRP, Hb, A/G) and age at onset were observed regarding the positivity. The risk that the ‘QRRAA’ positive subjects would suffer from RA was estimated to be about 1.3% which meant 7.2 times easier to get RA than those without ‘QRRAA’.

    Notes: Otolith microstructure of 308 juvenile jack mackerel Trachurus japonicus sampled in the southern Sea of Japan between June and September 2002 were examined by light microscopy. Hatch-date distribution indicated a protracted spawning season from 16 January to 30 May 2002. The first secondary primordium (SP) was formed at ages 19–54 days, with a mean ± s.d. of 30·4 ± 6·1. The number of SP in an otolith ranged from two to 15, with a mean of 6·1 ± 1·7. Age of the first SP formation, number of SP and increment width varied with hatch date. In general, late-hatched fish were younger when the first SP formed, and had a higher number of SP and wider increments, than early-hatched fish. As increment width is a linear function of somatic growth and formation of the first SP is associated with metamorphosis in jack mackerel, these variations in otolith microstructure indicated that rates of growth (as inferred from wider increments) and development (as inferred by younger age of first SP formation) were higher in late-hatched fish relative to early-hatched fish. Higher temperature experienced by late-hatched fish during early life stages may contribute critically to their higher growth and development rates compared to early-hatched fish.

    Notes: The daily periodicity of growth increment formation in sagittal otoliths of jack mackerel Trachurus japonicus was validated by marking otoliths with alizarin complexone (ALC). Analysis of otoliths of known-age juveniles confirmed that the first increment formed on day 3 after hatching, and was associated with first feeding. A total of 198 specimens, ranging from 2·6 to 49·2 mm in body length (notochord length or standard length) and from 7 to 78 days in age, were collected in the East China Sea and Tosa Bay, and used to examine the association between otolith morphological development and ontogenetic development. The relationship between body length (L) and otolith radius (R) was significantly described by the linear function L = 2·65 + 0·0425R(n = 198, r2 = 0·99, P 〈 0·001), indicating that somatic growth history can be reconstructed from otolith growth patterns. The otolith was primarily spherical in the preflexion larval stage, and became elongated with notochord flexion. The first secondary primordium formed at c. 25 days, during the middle postflexion stage, and was associated with metamorphosis. By c. 42 days the sagittal otolith was adult-like in morphology, with the primary growth zone enclosed by the marginal growth zone, except in the anterior rostrum area. Thus age, growth and developmental stages were recorded in sagittal otoliths during the larval and early juvenile stages of jack mackerel.

    Notes: Larval and early juvenile growth was backcalculated for individual Japanese sardines Sardinops melanostictus using the biological intercept method based on the allometric relationship between otolith radii and fish lengths. Sardines grew at 0·81 mm day−1 during the larval stage. In the early juvenile stage, they grew from 32·3 to 45·4 mm fork length (L) over a 20-day period (0·64mm day−1). Using the observed relationship between L and wet body weight (W), W = 0·00942 L2.99, W of the sardine juveniles was calculated to increase from 306 to 832 mg during the 20-day period. The carbon (C) requirement to achieve this growth in weight was estimated to increase from 5·7 to 9·6 mg day−1. Stomach contents of the sardines were composed mostly of copepods (73%) and larvaceans (25%). Wet stomach content weight (Ws) was expressed by a power function of the W, Ws=0·731 W0·658. Carbon and nitrogen constituted 41·7 ± 1·5 and 10·0 ± 0·4% of the dry Ws, respectively. Stomach C content increased from 2·0 to 3·9 mg during the 20-day period. Three to four cycles of the daily turnover of stomach contents during the 16 h of daytime, corresponding to a gastric evacuation rate of 0·2–0·3 h−1 under continuous feeding, met the C requirement to achieve the backcalculated growth in early juvenile sardines. The Kuroshio frontal waters seem to provide Japanese sardine juveniles with favourable growth conditions.

    Notes: The marginal increment growth in sagittal otoliths of the myctophid larvae Diaphus slender-type spp. collected in the north-eastern East China Sea was examined based on specimens collected at different times of the day. The calcification of the incremental zone began after midnight and took place throughout the day, and the discontinuous zone was formed only around midnight. These results indicate that otolith increments are formed daily.
