Femoral shaft fracture in children is a frequently encountered problem. Residual leg length discrepancy persisting at skeletal maturity is the most common complication. In this study, a positive correlation was found between the amount of bone fragments overlap and the overgrowth phenomenon. When comparing final leg-length discrepancy with initial fragments overlap, 9.3 mm was found to be the m...

Menticirrhus americanus were sampled (n = 393) from two beaches (P1 is an estuarine beach near the mouth of Paranaguá Estuarine Complex, and P2 a adjacent to Complex) in subtropical region western South Atlantic waters between August 2015 June 2016. This study aimed identify spawning season age structure for M. using sampling methods. For at P1 beach, seine, line, pole used, while samples obtai...

Among fruit-fly species of the genus Drosophila there is remarkable variation in sperm length, with some species producing gigantic sperm (e.g., > 10 times total male body length). These flies are also unusual in that males of some species exhibit a prolonged adult nonreproductive phase. We document sperm length, body size, and sex-specific ages of reproductive maturity for 42 species of Drosop...

The reproductive biology of the tarwhine Rhabdosargus sarba has been studied in three very di¡erent environments in Western Australia, namely the lower reaches of the Swan River Estuary and marine waters at the same latitude, i.e. *328S, and a large subtropical marine embayment (Shark Bay) approximately 800 km further north. A macroscopic and histological examination of the gonads demonstrated ...

Reproductive characteristics of a fish stock provide important tools for assessing population health. Change in length-at-maturity ( L 50 ) is potential indicator exploited populations but when criteria determining maturity classifications are inconsistent, it difficult to accurately assess change over time and space. Etelis coruscans commercially eteline snapper found throughout the Indo-Pacif...
