BMC Health Services Research is abstracted and indexed in PubMed, MEDLINE, Chemical Abstracts Service, EMBASE, Scopus, CINAHL, Current Contents, and CAB International.The journal is included in the Web of Science and according to the Journal Citation Reports has a 2018 impact factor of 1.932.
Terpenoids are modified terpenes, [7] wherein methyl groups have been moved or removed, or oxygen atoms added. Some authors use the term "terpene" more broadly, to include the terpenoids. Just like terpenes, the terpenoids can be classified according to the number of isoprene units that comprise the parent terpene:
The journal covers research, methods, and concepts related to the financing, organization, delivery, evaluation, and outcomes of health services. According to the Journal Citation Reports , the journal has a 2020 impact factor of 3.402, ranking it 18th out of 88 journals in the category "Health Policy" [ 1 ] and 38th out of 108 in "Health Care ...
Terpenes are classified by the number of carbons: monoterpenes (C 10), sesquiterpenes (C 15), diterpenes (C 20), as examples. The terpene alpha-pinene is a major component of the common solvent, turpentine. The one terpene that has major applications is natural rubber (i.e., polyisoprene).
Because impact factor is commonly accepted as a proxy for research quality, some journals adopt editorial policies and practices, some acceptable and some of dubious purpose, to increase its impact factor. [38] [39] For example, journals may publish a larger percentage of review articles which generally are cited more than research reports. [8]
Monoterpenes are a class of terpenes that consist of two isoprene units and have the molecular formula C 10 H 16. Monoterpenes may be linear (acyclic) or contain rings (monocyclic and bicyclic). Modified terpenes, such as those containing oxygen functionality or missing a methyl group, are called monoterpenoids. Monoterpenes and monoterpenoids ...
Although a wide range of terpene structures exist, few of them are biologically significant; by contrast, diterpenoids possess a rich pharmacology and include important compounds such as retinol, phytol or taxadiene.
The vast heterogeneity of structures underlying this class of compounds makes generalizations difficult; they're a subclass of terpenoids, oxygenated derivatives of terpene hydrocarbons. Terpenes in turn are formally made up of five-carbon isoprene units (The alternate steroid base is a terpene missing a few carbon atoms). Derivatives are ...
