Viral quasispecies A viral quasispecies is a group of viruses related by a similar mutation or mutations, competing within a highly mutagenic environment The theory predicts that a viral quasispecies at a low but evolutionarily neutral and highly connected that is, flat region in the fitness landscape will outcompete a quasispecies located at a higher but narrower fitness peak in which the surrounding mutants Species In biology, a species is the basic unit of classification and a taxonomic rank, as well as a unit of biodiversity, but it has proven difficult to find a satisfactory definition.Scientists and conservationists need a species definition which allows them to work, regardless of the theoretical difficulties If as Linnaeus thought, species were fixed and clearly distinct from one another, there A list of Species Concepts Evolving Thoughts Oct , Here is a working list of species concepts presently in play I quote Concepts above because, for philosophical reasons, I think there is only one concept species , and all the rest Influenza virology Soon after the new influenza HN strain emerged in April , I began a series of blog posts on basic aspects of influenza virus replication and pathogenesis The goal of this series is to provide information that will allow everyone to better understand the events surrounding emergence and spread Virology A new class is starting at virology blog Virology I began this blog in , to give back what I ve learned from studying viruses for years I ve written many posts on basic virology, but they tend to disappear with time To remedy this problem, I ve collected all these posts with Palaeos Evolution Glossary Acquired trait A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation for example, the large muscles of a weightlifter PBS evolution Glossary digital PCR on Gene Quantification.Info Digital PCR dPCR is a refinement of conventional PCR methods that can be used to directly quantify and clonally amplify nucleic acids including DNA, cDNA, methylated DNA, or RNA. Table of Contents The following provides a kind of standard ordering of the nodes in the Principia Cybernetica Web, in the form of an outline This outline can be read as if it were the table of contents of a book, with subsequent chapters, sections, subsections, etc. NSA inhibitors in the treatment of hepatitis C Hepatitis C virus infection is a major health problem worldwide and no vaccine has yet been developed against this virus In addition, currently approved pharmacotherapies achieve suboptimal cure rates and have side effects that result in non compliance and premature treatment discontinuation. The Case Against HIV, collated by Henry Bauer That HIV causes AIDS has been the officially sanctioned view for about decades, believed almost universally but questioned openly by thousands of people A comprehensive reading of the mainstream literature together with analysis of mainstream data demonstrates conclusively that HIV is neither a necessary nor a sufficient cause of AIDS.
