The genus Rickettsia (Rickettsiales: Rickettsiaceae) consists of small, obligately intracellular Gram-negative bacteria that have been studied principally as established and newly emerging human pathogens transmitted by specific blood-feeding arthropods [1], [2].
Brands are applied to animals principally to establish ownership, but they are also used widely for keeping records of purebred lines and for identification in disease control and age differentiation.
The British National Space Centre was established principally to work on the problem.
Electric Masada plays the Masada songbook, established principally by Mr. Zorn's acoustic jazz quartet; while the quartet is often described in shorthand as Jewish-sounding early Ornette Coleman, the larger electric sextet gets grander, more cinematic ideas.

Developmental roles have been established principally for some of the "endogenous" CYPs.
The knowledge about the damage induced by environmental agents at epigenetic level is well established principally at DNA level, in spite of the fact that the role of noncoding RNAs has become visible more recently.
The benefit of mammographic screening was established principally from mortality data on women screened at age 50 or older, and while comparable data in younger women are available from some of the RCTs, none included sufficient numbers to reliably estimate the mortality effect.
