Because more people are dying at very advanced ages with multiple system failure, it’s often harder for physicians to pinpoint the specific underlying cause, but using “old age” as a catch-all term could make mortality data less meaningful, the article said. An upcoming revision of the International Classification of Diseases might provide some guidance: “Each revision of the ICD is the right moment to reconsider this question,” the co-head of the ICD’s mortality statistics committee told the Post.

Consequently, many precancerous lesions are simply not recognized as such, and cannot be included in clinical trials that assess the effectiveness of precancer treatments.For example, lymphoma experts do not use the terms "precancer" or "prelymphoma" [prelymphomas are lesions that precede the development of lymphomas].In a recent article, Elaine Jaffe discussed a condition that can be detected by flow cytometry in which monoclonal populations of CD5+ B-cells are found in 3% of healthy adults over the age of 40.Jaffe ES.

Salmonella identification below species level is most often limited to phenotypic typing methods such as biochemical and serological identification, which are costly, time-consuming and do not always reflect the evolution of Salmonella groups. Newer methods for Salmonella typing and subtyping include genome-based methods such as pulsed field gel electrophoresis (PFGE), Multiple Loci VNTR Analysis (MLVA), Multilocus sequence typing (MLST) and (multiplex-) PCR-based methods. In the last years further mo...

Gerlach writing in Salmonella: From Genome to Function:Most Salmonella strains contain prophages or remnant phages and release them spontaneously. Special bacteriophages were developed and used in phage typing systems for epidemiological work all over the world since 1947 to control salmonellosis. This method provides fast and inexpensive characterization of frequent serovars such as S. Typhimurium or S. Typhi on the sub-serovar level and is especially useful for primary analysis before investigation by other, more expensive molecular techniques such as sequencing. Prophages are themselves not only variable elements in a chromosome but also variable by module exchange within the...

For the higher taxa there even is no official nomenclature: the rules of the International Code of Nomenclature of Prokaryotes do not cover taxa above the rank of class. The most commonly accepted division of the prokaryotes in two "subkingdoms" or "domains" (Bacteria and Archaea) and the classification of their species with validly published names in respectively 27 and 2 "phyla" or "divisions" (as of November 2009) is primarily based on 16S rRNA sequence comparisons. This type of classification was adopted in the latest edition of Bergey's Manual of Systematic Bacteriology. Alternative classifications have been proposed as well, based e.g. on the structure of the cell wall. Some 16S rRNA sequence-based phyla unite prokaryotes of similar...

Reports on social inequalities in female mortality and is the first official compilation of detailed mortality statistics for women based on the NS-SEC. The results demonstrate a strong socio-economic effect on the mortality of women in all regions.

Over 30 years ago virologist David Baltimore devised an alternative classification scheme that takes into account the nature of the viral nucleic acid. One of the most significant advances in virology of the past 30 years has been the understanding of how viral genomes are expressed. Cellular genes are encoded in dsDNA, from which mRNAs are produced to direct the synthesis of protein. Francis Crick conceptualized this flow of information as the central dogma of molecular biology: DNA —> RNA —> protein All viruses must direct the synthesis of mRNA to produce proteins. No viral genome e... virology blog blogs http://www.medworm.com/rss/comments.php?id=2726973 Wed, 12 Aug 2009 16:12:08 +0100 2726973 http://www.medworm.com/index.php?rid=2741080&cid=t_172235_139_f&fid=38879&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2FVirologyBlog%2F%7E3%2FcEH9tDc1aKQ%2F For the first 60 years of virus discovery, there was no system for classifying viruses. Consequently viruses were named haphazardly, a practice that continues today. Vertebrate viruses may be named according to the associated diseases (poliovirus, rabies), the type of disease caused (murine leukemia virus), or the sites in the body affected or from which the virus was first isolated (rhinovirus, adenovirus). Some viruses are named for where they were first isolated (Sendai virus, Coxsackievirus), for the scientists who discovered them (Epstein-Barr virus), or for the way people imagined they were contracted (dengue = ‘evil spirit’; influenza = ‘influence’ of bad air). By the early 1960s, new viruses were being discovered and studied by electron microscopy.

It also contains a large number of unclassified neoplasm terms as addendum items. It is, by far and away, the world's largest neoplasm nomenclature. The classification is available in XML, RDF and flat-file formats. Here is the preface text distributed with each formatted version:"This file was prepared by Jules J. Berman.
