    Abstract This study was designed to estimate the optimal dietary protein level for juvenile Pacific threadfin fed two levels of dietary lipid. Ten semi-purified diets were formulated to contain five levels of dietary protein (25, 30, 35, 40 and 45%) at either 10 or 14% dietary lipid. A commercial diet containing 14% lipid and 50% protein was fed as a reference treatment. Juvenile threadfin (initial body weight, 3.4g) were hand fed these diets at 7% body weight/day for 8weeks with 3 replications per dietary treatment. Fish were cultured in an indoor flow-through system with 31‰ seawater at 26°C. There were 20 fish per replicate. The dietary lipid levels did not cause significant changes in growth performance or body composition (P>0.05). In contrast, the diet with 25% protein resulted in significantly (P<0.05) lower weight gain and higher feed conversion ratios (FCR) than the diets with 30–45% protein. The lowest FCR occurred in fish fed diets containing 35% protein and 10% lipid or 30% protein and 14% lipid. Increased dietary protein level resulted in decreased protein efficiency ratio, hepatosomatic index, and lipid level in carcass or whole fish. Protein and energy retentions in carcass or whole fish were negatively correlated to dietary protein levels. Estimation using a polynomial model, 41% protein supported maximum growth of Pacific threadfin under these experimental conditions. Fish fed the test diets containing 35% protein, however, had similar growth performance but better protein utilization than fish fed either the commercial feed or the diet with 40% protein. These results demonstrate the possibility of reducing protein content in commercial feeds and thus lowing feed costs needed for Pacific threadfin culture.

    Abstract The objectives of this study were to develop an amino acid test diet for Pacific threadfin ( Polydactylus sexfilis) and estimate its lysine (Lys) requirement based on growth performance. A basal test diet was formulated using Pacific threadfin muscle and a mixture of precoated crystalline amino acids as the protein sources to achieve the same amino acid profile as in Pacific threadfin muscle with the exception of Lys. An 8-week growth trial was conducted with juvenile fish (initial body weight, 3.0±0.1g) fed eight isonitrogenous (35% crude protein) and isoenergetic (19.1MJ/kg diet) semi-purified diets containing 1.26% to 2.91% Lys. The fish were cultured in an indoor flow-through system with 31‰ seawater at 25°C. There were three replicate groups per dietary treatment. No mortalities occurred during the growth trial. Fish fed diets containing 2.23-2.43% Lys had higher specific growth rate, feed efficiency, protein efficiency ratio and protein retention than those fed diets containing less than 1.69% Lys. Excess dietary Lys also decreased growth of fish significantly. The basal diet (1.26% of Lys) resulted in higher liver but lower carcass to body weight ratio. Fish fed the diet containing 1.26% Lys showed significantly higher whole-body lipid and energy levels but lower moisture and protein levels than those fish fed the other diets. Broken-line analysis of the growth data indicated that the Lys requirement was 1.79% of diet (5.1% protein) under current culture conditions.

    Abstract The relationship between dietary intake and systemic availability of retinol is likely to be complex because although retinol is an essential nutrient, it is toxic at high levels. The present study determined whether rates of transapical retinol absorption are modulated so that availability is increased at low dietary levels, but decreased when dietary intake is excessive. Juvenile hybrid striped bass were fed for 6 wk diets with 568 (below), 1657 (approximating the requirement) and 40,244 (excessive) micro g/kg dry diet of trans retinol. Proximal small intestine segments were used to measure rates of retinol absorption and tissue concentrations. Initial and final body mass did not differ among groups; deficiency and toxicity symptoms were not observed. Uptake of tracer retinol was inhibited by unlabeled retinol, indicating the presence of saturable, carrier-mediated absorption. Increasing dietary levels of retinol increased the rates of absorption measured at 0.05 mmol/L [8.04 +/- 0.65; 15.2 +/- 1.53; 25.1 +/- 3.4 pmol/(mg. min) for below, approximating and exceeding the retinol requirement; P < 0.0001]; this resulted in higher tissue concentrations of all-trans retinol (0.21 +/- 0.03, 0.49 +/- 0.21 and 338 +/- 89 pmol/g; P < 0.0001) and dehydro-retinol (0.11 +/- 0.04, 0.91 +/- 0.04, and 454 +/- 109 pmol/g; P < 0.001). These findings suggest that the systemic availability of various dietary levels of retinol is modulated after transapical absorption.

    Abstract Unconventional T cells such as γδ T cells, natural killer T cells (NKT cells) and mucosal-associated invariant T cells (MAIT cells) are a major component of the immune system; however, the cytokine signaling pathways that control their development and function in humans are unknown. Primary immunodeficiencies caused by single gene mutations provide a unique opportunity to investigate the role of specific molecules in regulating human lymphocyte development and function. We found that individuals with loss-of-function mutations in STAT3 had reduced numbers of peripheral blood MAIT and NKT but not γδ T cells. Analysis of STAT3 mosaic individuals revealed that this effect was cell intrinsic. Surprisingly, the residual STAT3-deficient MAIT cells expressed normal levels of the transcription factor RORγt. Despite this, they displayed a deficiency in secretion of IL-17A and IL-17F, but were able to secrete normal levels of cytokines such as IFNγ and TNF. The deficiency in MAIT and NKT cells in STAT3-deficient patients was mirrored by loss-of-function mutations in IL12RB1 and IL21R, respectively. Thus, these results reveal for the first time the essential role of STAT3 signaling downstream of IL-23R and IL-21R in controlling human MAIT and NKT cell numbers.
