It is unlikely that any serious attempt will be made to standardize bacterial nomenclature on a national or international scale until the implementation of the proposed revision of the International Code of Nomenclature of Bacteria on 1 January 1980. In the meantime, the lack of such standardization poses major problems in communication between the laboratory and the clinican and also causes di...
The male fertility restorer (RF) proteins belong to extended protein families associated with the cytoplasmic male sterility in higher plants. Up till now, there is no devised nomenclature for naming the RF proteins. The systematic sequencing of new plant species in recent years has uncovered the existence of several novel RF genes and their encoded proteins. Their naming has been simply arbitr...
Guidelines for human gene nomenclature were first published in 1979 [1], when the Human Gene Nomenclature Committee was first given the authority to approve and implement human gene names and symbols. Updates of these guidelines were published in 1987 [2], 1995 [3], and 1997 [4]. With the recent publications of the complete human genome sequence there is an estimated total of 26,000–40,000 gene...

The hypoplastic left heart syndrome encompasses a spectrum of cardiac malformations that are characterized by significant underdevelopment of the components of the left heart and the aorta, including the left ventricular cavity and mass. At the severe end of the spectrum is found the combination of aortic and mitral atresia, when the left ventricle can be close to non-existent. At the mild end ...
An essential component of microtubules, α-tubulin is also a multigene family in many species. An orthology-based nomenclature for this gene family has previously been difficult to assign due to incomplete genome builds and the high degree of sequence similarity between members of this family. Using the current genome builds, sequence analysis of human, mouse, and rat α-tubulin genes has enabled...
An algorithm for translating directly from chemical names to molecular formulas is described. The validity of the algorithm was tested both manually and by computer. Molecular formulas of several hundred randomly selected chemicals were calculated successfully, verifying the linguistic analyses and the logic of the computer program. The algorithm for manual human translation consists of eight s...
با استفاده از شواهد مورفولوژیک و جغرافیایی، نشان داده می شود که hesperis leucoclada boiss. و pseudofortuynia esfandiarii hedge مترادف اند. ترکیب جدید pseudofortuynia leucoclada boiss. (khosravi) نام صحیح تاکسون است. قرابت pseudofortuynia مورد بحث قرار می گیرد.
his issue of Emerging Infectious Diseases contains 2 independent reports of Rickettsia sibirica infections in Spain and Portugal. The authors identify the agent both as a subspecies (1) and as a strain (2). This inconsistency refl ects a lack of consensus regarding the use of subspe-cies designations for Rickettsia taxa, so appropriate designation of these pathogens as strains or subspecies rem...
