The importance of genes of major effect for evolutionary trajectories within and among natural populations has long been the subject of intense debate. For example, if allelic variation at a major-effect locus fundamentally alters the structure of quantitative trait variation, then fixation of a single locus can have rapid and profound effects on the rate or direction of subsequent evolutionary...

Tea is one of the most widely consumed beverages all over the world due to its beneficial health effects and special flavor and taste. Tagetes erecta, Telosma minor, Ixora coccinea, Nelumbo nucifera, Antigonon leptopus, Hibiscus rosa-sinensis, Bougainvillea glabra and Senna siamea are used as traditional edible and medicinal materials in Thailand. In this study, the total phenolic content and a...

This article reports the breaking of ethological barriers through the constitution of soma-germ line chimeras between species of the melanogaster subgroup of Drosophila, which are ethologically isolated. Female Drosophila yakuba and D. teissieri germ cells in a D. melanogaster ovary produced functional oocytes that, when fertilized by D. melanogaster sperm, gave rise to sterile yakuba-melanogas...

HYPOTHESIS Traumatic inferior shoulder dislocation (luxatio erecta) injuries are rare, comprising less than 0.5% of all shoulder dislocations. Few cases have been reported, and the outcome of treatment has been ill defined. MATERIALS AND METHODS Between 1968 and 2000, 18 patients (20 shoulders) with luxatio erecta were evaluated at our institution. Two patients (2 shoulders) were lost to foll...

conclusions these extracts can be used as antibacterial agents in treating infectious diseases. further studies are needed for considering this plant as an antibacterial plant and benefit from its clinical applications for routine use. background tagetes genus contains 56 species and is native in north and south america, but some have become widespread around the world. objectives this study wa...

La luxation de l'épaule, est définie par une perte de contact totale et permanente de la tête humérale avec la cavité glénoïde de la scapula, se produisant au décours d'un traumatisme. C'est une des urgences en chirurgie orthopédique dans le sens où l'intervention doit intervenir rapidement. D'une part pour le risque de compression d'éléments nobles, mais aussi pour l'avenir de l'articulation (...

The Arabidopsis genome contains three ERECTA-family genes, ERECTA (ER), ERECTA-LIKE 1 (ERL1) and ERL2 that encode leucine-rich repeat receptor-like kinases. This gene family acts synergistically to coordinate cell proliferation and growth during above-ground organogenesis with the major player, ER, masking the loss-of-function phenotypes of the other two members. To uncover the specific develop...

Arabidopsis trichomes are single-celled epidermal hairs that serve as a useful model for the study of plant cell differentiation. An examination of the distribution of trichomes early in their development revealed that developing trichomes occur adjacent to another trichome much less frequently than would be expected by chance. Clonal analysis of epidermal cell lineages ruled out a role for cel...

Abstract The species of Pugilina cochlidium (Linnaeus, 1758) and P. erecta (Vermeij & Raben, 2009) has been studied in the present study. female can be differentiated from male by absence cephalic penis a complicated genital aparatus visible through mantle skirt both sexes. In other aspects external features are quite to males. digestive system was similar with few differences structure bet...

The popularity of natural dyes is steadily increasing due to their properties such as soothing colors, non-carcinogenic & non-hazardous nature, and also being safe for the environment. Some have been reported antibacterial properties. This study was performed explore efficiency selected plant products that were used in dyeing fabric. Flowers Butea monosperma Tagetes erecta dye extraction. Banan...
