fish larvae have a high requirement of amino acid (aa) for energy production and growth. this study was aimed to increase knowledge of aa profile during feral carp larval ontogeny and estimate larval aa requirements. larvae were collected randomly at 1, 3, 7, 11, 15, 19, 26 and 33 days post hatch for growth and aa analysis. the composition of total aa changed significantly during ontogeny. the ...

643 In everyday life, we operate on a very broad range of time scales, from sub-milliseconds to years. For instance, we perceive two clicks that are closer together than 50 milliseconds as a single event, even though we detect the timing differences. (We use them to localize sounds in space and to discriminate between syllables in speech.) If the same clicks are presented repetitively at interv...

Background: Alopecia Areata (AA) is a recurrent non-scarring type of hair loss that can affect any hair-bearing area. Prognosis of AA is unpredictable and most patients experience more than one episode of hair loss. The purpose of this study was to investigate the relationship between the severity of AA with respect to age of onset, nail involvement, family history, number of recurrences and du...
