A COMPREHENSIVE MOLECULAR PHYLOGENY OF DALYTYPHLOPLANIDA (PLATYHELMINTHES: RHABDOCOELA) REVEALS MULTIPLE ESCAPES FROM THE MARINE ENVIRONMENT AND ORIGINS OF SYMBIOTIC RELATIONSHIPS.

In this study we elaborate the phylogeny of Dalytyphloplanida based on complete 18S rDNA (156 sequences) and partial 28S rDNA (125 sequences), using a Maximum Likelihood and a Bayesian Inference approach, in order to investigate the origin of a limnic or limnoterrestrial and of a symbiotic lifestyle in this large group of rhabditophoran flatworms.T

Abstract Particle filtering is a numerical Bayesian technique that has great potential for solving Scarf sequential estimation problems involving non-linear and non-Gaussian models.Since the estimation accuracy achieved by particle filters improves as the number of particles increases, it is natural to consider as many particles as possible.MapRedu

Abstract Background "Evergreening" refers to the numerous strategies whereby owners of pharmaceutical products use patent laws and minor drug modifications to extend their monopoly privileges on the drug.We aimed to evaluate the impact of evergreening through the case study of the antidepressant citalopram and its chiral switch form escitalopram by

Abstract Background A premature luteinizing hormone (LH) surge refers to an endogenous Body Cleanser LH peak that occurs before follicle maturation or human chorionic gonadotropin injection in the process of controlled ovarian hyperstimulation.The effect of premature LH surge on pregnancy outcomes in fresh embryo transfer cycles is still controvers
