The study evaluated the role of different substrates on water quality, growth and survival of Labeo victorianus fry. Random sampling was used to select 225 fry, stocked at 100/mp>3p> and fed on shell free artemiap>®p> (40% - 60% crude protein). Each treatment was carried out in triplicates using gravel and sand as substrates and water media without substrate (control). Growth and survival of the fry was monitored over 4 weeks period at a hatchery set-up. physicochemical parameters were measured weekly while mortality was documented daily. Substrate type had an effect on water quality, growth and survival of fry. Dissolved Oxygen, growth and survival was higher in tanks under gravel substrate than sand and control while mortality was higher (22%) for sand (p ≤ 0.05) than gravel and sand treatments. Fry in gravel substrate had the best growth response (1.77 ± 0.92 g) while control and sand recorded 1.57 ± 0.90 g and 1.45 ± 0.97 g respectively. In contrast, growth was homogenous during the first 2 weeks of the trial but gravel substrate fry significantly out-grew sand and control in the remaining 3 weeks. However, fry in sand and control experienced compensatory growth towards the end of the study. Therefore, gravel substrate enhances L. victorianus performance and is recommended in the introduction of the species into aquaculture and re-stocking back to the wild.

已往的研究对于实验室应用的各种啮齿类动物,如大鼠和小鼠骨骼肌蛋白表达的特性已有报道。然而,至今不清楚其它啮齿类动物如野生鼠骨骼肌蛋白的表达或性双态性的特征,而这些野生鼠的行为学、形态学及生理学特点均已有报道。已知骨骼肌的肌球蛋白重链( MHC)成分与其功能特性有关。我们研究了草原田鼠的肱三头肌、胫骨前肌、腓肠肌和比目鱼肌MHC蛋白表达的性别特性。应用SDS聚丙烯酰胺凝胶电泳法测定MHCⅠ型、Ⅱa型、Ⅱd/x和Ⅱb型的蛋白表达相对含量。结果表明:与雌鼠相比,雄鼠的比目鱼肌湿重较大,胫骨前肌的MHCⅡa蛋白量表达较高。未见骨骼肌重量及MHC蛋白表达含量在雌雄鼠间的性别差异。血中睾酮的浓度差异可能不影响外周骨骼肌蛋白的表达特性。然而,与过去在大鼠、兔和小鼠中的已报道的结果相比,草原田鼠骨骼肌MHC的表达显示了更多异质性。推测这可能与草原田鼠和其它小型哺乳类动物生存的自然环境和功能需要有关。

Body Composition and performance Capabilities Based on protein Intake in Collegiate Dancers： A pilot Study

Journal of Sports Science 2017年第4期5卷 189-197页

作者： Ann Frost Brown Christopher William Bach Giuliana De Almeida Shawn leonard Tom Welsh Michael James Ormsbee Institute of Sports Sciences and Medicine Department of Nutrition Food and Exercise Sciences Florida State UniversityTallahassee FL 32306 USA Department of Movement Sciences University of Idaho Moscow ID 83843 USA University of Nebraska-Lincoln Nebraska Athletic Performance Laboratory Lincoln NE 68588 USA School of Dance Florida State University Tallahassee FL 32306 USA Department of Biokinetics Exercise and Leisure Sciences University of KwaZulu-Natal Durban 4000 South Africa

The aesthetic nature of dance places pressure on the athlete to have low body weight and fat and despite data showing higher protein intake improving body composition in numerous populations, a paucity of data exists on dancers. Therefore, the purpose of this study was to examine associations between protein intake, body composition and performance among dancers. Female dancers （n = 25; age 20.7 ± 1.8 years; mean ± SD） completed three-day diet logs, body composition （DXA）, and performance testing. protein intake was expressed as g/kg/day and three equal tertiles were created （Low protein： Lp, 〈 1.2 g/kg/day; Moderate protein： Mp, 1.2-1.6 g/kg/day; High protein： Hp, 〉 1.6 g/kg/day）. Data were analyzed using one-way ANOVA to compare group means with significance at p 〈 0.05. protein and energy intake were greater in Hp compared to Lp （p = 0.001, 0.033, respectively）. The only performance difference observed was peak horizontal force （AMTI force platform） which was significantly greater in Hp compared to Lp （Lp： 295.7 ± 111.1N, Hp： 419.9 ± 76.7N; p = 0.029）. In conclusion, no significant differences were found between protein tertiles and body composition. Nevertheless, protein intake may be physiologically important to dancers when combined with evidence from other athletic .populations indicating high protein and energy intake may be beneficial to body composition.
