| Abstract Background Sperm contains a wealth of cell surface receptors and ion channels that are required for most of its basic functions such as motility and acrosome reaction. Conversely, animal venoms are enriched in bioactive compounds that primarily target those ion channels and cell surface receptors. We hypothesized, therefore, that animal venoms should be rich enough in sperm-modulating compounds for a drug discovery program. Our objective was to demonstrate this fact by using a sperm-based phenotypic screening to identify positive modulators from the venom of Walterinnesia aegyptia. Methods Herein, as proof of concept that venoms contain interesting compounds for sperm physiology, we fractionated Walterinnesia aegyptia snake venom by RP-HPLC and... |

| Background Originating from Northeast Asia, the Pacific oyster Crassostrea gigas has been introduced into a large number of countries for aquaculture purpose. Following introduction, the Pacific oyster has turned into an invasive species in an increasing number of coastal areas, notably recently in Northern Europe. Methods To explore potential adaptation of reproductive traits in populations with different histories, we set up a common garden experiment based on the comparison of progenies from two populations of Pacific oyster sampled in France and Denmark and their hybrids. Sex ratio, condition index and microarray gene expression in gonads, were analyzed in each progeny (n = 60). Results A female-biased sex-ratio and a higher condition index were... |

| The reproductive success of the oriental peach moth was evaluated in four experiments: 1) assessment of the mating duration, fecundity, fertility and longevity of females paired with virgin and immediately mated males; 2) mating duration, spermatophore size, fecundity, fertility and longevity in females paired with virgin and up to four times mated males; 3) receptivity of females to additional copulations after mating with virgin or mated males, and the effects of this behavior in female fecundity, fertility and longevity; 4) influence of insects age in the reproductive output. Males (33%) could copulate immediately after a previous copula. They were fertile until the fourth mating, but only in the first copula they transferred the longest (1.43 ± 0.10... |

| The age at menarche is an indicator of racial, geographical and nutritional patterns of different societies. This cross-sectional study conducted on 1223 girls aged 14-20 in the Markazi (Central) Province, Iran in 2010. In this research, the age at menarche, as the main variable, was determined for each city and compared between different cities. The statistical analyses included c2 test for determining statistically significant differences, variance analysis for determining the difference between groups, and Pearson correlation coefficient for determining the relationship between variables. The average age of first menstruation was 13.21±1.33 years in the Markazi Province, with no significant difference among the cities of the province. This age is... |

| Biochar land application research in elevated rainfall areas (980 millimeters of annual rainfall) of the U.S. Pacific Northwest is lacking. A proof-of-concept field study examined the effects of spruce-pine-fir wood chip biochar (slow pyrolysis; 450-500 degrees Celsius; 35 megagrams per hectare), dairy manure compost (105 megagrams per hectare), compost + biochar (35 and 105 megagrams per hectare, respectively), and a control (no biochar or compost) on glacially altered soil (sandy or loamy skeletal, isotonic, mesic humic or aquic Dystroxerepts) chemical properties and growth characteristics of vetch and sweet corn over a growing season. In-season liming (5.4 megagrams per hectare) occurred to raise the soil pH for adequate crop growth. Biochar, alone... |

| Avaliacao da eficiencia e efeito residual de diversos fosfatos em Latossolo Vermelho Amarelo do submedio Sao Francisco. Constituiu-se de dois experimentos, o primeiro foi avaliada a eficiencia dos seguintes fosfatos na produtividade do milho var. Centralmex: catalao moido, catalao 350, catalao 600, catalao tratado termicamente, patos moidos; patos 250, patos 600, patos tratado termicamente, araxa moido e araxa tratado termicamente. Foi avaliado, tambem, o efeito residual desses fosfatos atraves de dois ciclos da cultura do milho. O segundo expeimento foi realizado com as mesmas caracteristicas do anterior. Como fontes de fosforo foram usados os seguintes produtos: termofosfato goisfertil; fosfato RNC, dapinho, fosfatos parcialmente acidulados fosforico. |

| Atraves da analise de solo, foi realizada uma avaliacao da fertilidade do solo em uma area de 1.100 ha do perimetro irrigado do Projeto de Irrigacao de Bebedouro, apos 13 anos de exploracao. Os dados dos elementos obtidos, foram comparados com os do solo virgem e classificados em niveis baixo, medio e alto. Quando comparado o solo em estudo com o solo virgem, houve aumento nos teores de potassio, fosforo, calcio, magnesio e da condutividade eletrica, e um decrescimo do teor de sodio, e o valor do pH praticamente nao se alterou. No que se refere a classificacao dos niveis, constatou-se que a maior parte da area do Projeto apresentou niveis altos de potassio, niveis medios de fosforo, calcio, magnesio e pH e niveis baixos de aluminio e da Capacidade de Troca... |
